CHAPTER VIII.

THE GERMAN ILLUMINATION.

%1. The Contemporaries of Leibnitz.%

The period between Kepler and Leibnitz in Germany was very poor in

noteworthy philosophical phenomena. The physicist, Christoph Sturm[1] of

Altdorf (died 1703), was a follower of Descartes, Joachim Jungius[2] (died

1657) a follower of Bacon, though not denying with the latter the value of

the mathematical method in natural science. Hieronymus Hirnhaym, Abbot at

Prague (_The Plague of the Human Race, or the Vanity of Human Learning_,

1676), declared the thirst for knowledge of his age a dangerous disease,

knowledge uncertain, since no reliance can be placed on sense-perception

and the principles of thought contradict the doctrines of faith, and

harmful, since it contributes nothing to salvation, but makes its

possessors proud and draws them away from piety. He maintained, further,

that divine authority is the only refuge for man, and moral life the true

science. Side by side with such skepticism Hirnhaym's contemporary, the

poet Angelus Silesius (Joh. Scheffler, died 1667), defended mysticism.

The teacher of natural law, Samuel Pufendorf[3] (1632-94, professor in

Heidelberg and Lund, died in Berlin), aimed to mediate between Grotius and

Hobbes. Natural law is demonstrable, its real ground is the will of God,

its noëtical ground (not revelation, but) reason and observation of the

(social) nature of man, and the fundamental law the promotion of universal

good. The individual must not violate the interests of society in

satisfying his impulse to self-preservation, because his own interests

require social existence, and, consequently, respect for its conditions.

Imperii Germanici_, 1667, under the pseudonym Monzambano; _De Jure Natures

et Gentium_ 1672, and an abstract of this, _De Officio Hominis et Civis_,

1673.]

Pufendorf was followed by Christian Thomasius[1] (1655-1728; professor of

law at the University of Halle from its foundation in 1694). He was

the first instructor who ventured to deliver lectures in the German

language--in Leipsic from 1687--and at the same time was the editor of the

first learned journal in German (_Teutsche Monate, Geschichte der Weisheit

und Thorheit_). In Thomasius the characteristic features of the German

Illumination first came out in full distinctness, namely, the avoidance of

scholasticism in expression and argument, the direct relation of knowledge

to life, sober rationality in thinking, heedless eclecticism, and the

demand for religious tolerance. Philosophy must be generally intelligible,

and practically useful, knowledge of the world (not of God); its form, free

and tasteful ratiocination; its object, man and morals; its first duty,

culture, not learning; its highest aim, happiness; its organ and the

criterion of every truth, common sense. He alone gains true knowledge who

frees his understanding from prejudice and judges only after examining for

himself; the joy of mental peace is given to no one who does not free his

heart from foolish desires and vehement passions, and devote it to virtue,

to "rational love." The positive doctrines of Thomasius have less interest

than this general standpoint, which prefigured the succeeding period. He

divides practical philosophy into natural law which treats of the _justum_,

politics which treats of the _decorum_, and ethics which treats of the

_honestum_. Justice bids us, Do not to others what you would not that

others should do to you; decorum, Do to others as you would that they

should do to you; and morality, Do to yourself as you would that others

should do to themselves. The first two laws relate to external, the third

to internal, peace; legal duties may be enforced by compulsion, moral

duties not.

[Footnote 1: Thomasius: _Institutionum Jurisprudentiae Divinae Libri Tres_,

1688; _Fundamenta Juris Naturae et Gentium_, 1705, both in Latin; in

German, appeared in 1691-96 the _Introduction and Application of Rational

and Moral Philosophy_.]

If Thomasius was the leader of those popular philosophers who, unconcerned

about systematic continuity, discussed every question separately before

the tribunal of common sense, and found in their lack of allegiance to

any philosophical sect a sufficient guarantee of the unprejudicedness

and impartiality of their reflections, Count Walter von Tschirnhausen

(1651-1708; _Medecina Mentis sive Artis Inveniendi Praecepta Generalia_,

1687), a friend of Spinoza and Leibnitz, became the prototype of another

group of the philosophers of the Illumination. This group favored

eclecticism of a more scientific kind, by starting from considerations

of method and seeking to overcome the antithesis between rationalism and

empiricism. While fully persuaded of the validity and necessity of the

mathematical method in philosophical investigations, as well as elsewhere,

Tschirnhausen still holds it indispensable that the deductions, on the one

hand, start from empirical facts, and, on the other, that they be confirmed

by experiments. Inner experience gives us four primal facts, of which the

chief is the certainty of self-consciousness. The second, that many things

affect us agreeably and many disagreeably, is the basis of morals; the

third, that some things are comprehensible to us and others not, the

basis of logic; the fourth, that through the senses we passively receive

impressions from without, the basis of the empirical sciences, in

particular, of physics. Consequently consciousness, will, understanding,

and sensuous representation _(imaginatio)_, together with corporeality,

are our fundamental concepts. Not perception _(perceptio)_, but conception

_(conceptio)_ alone gives science; that which we can "conceive" is true;

the understanding as such cannot err, but undoubtedly the imagination can

lead us to confuse the merely perceived with that which is conceived. The

method of science is geometrical demonstration, which starts from

(genetic) definitions, and from their analysis obtains axioms, from their

combination, theorems. That which is thus proved _a priori_ must, as

already remarked, be confirmed _a posteriori_. The highest of all sciences

is natural philosophy, since it considers not sense-objects only, not (like

mathematics) the objects of reason only, but the actual itself in its true

character. Hence it is the divine science, while the human sciences busy

themselves only with our ideas or the relations of things to us.

%2. Christian Wolff.%

Christian Wolff was born at Breslau in 1679, studied theology at Jena, and

in addition mathematics and philosophy, habilitated at Leipsic in 1703,

and obtained, through the instrumentality of Leibnitz, a professorship of

mathematics at Halle, in 1706. His lectures, which soon extended themselves

over all philosophical disciplines, met with great success. This

popularity, as well as the rationalistic tendency of his thinking, aroused

the disfavor of the pietists, Francke and Lange, who succeeded, in 1723, in

securing from King Frederick William I. his removal from his chair and his

expulsion from the kingdom. Finding a refuge in Marburg, he was called back

to Halle by Frederick the Great a short time after the latter's ascension

of the throne. Here he taught and wrote zealously until his death in 1754.

In his lectures, as well as in half of his writings,[1] he followed the

example of Thomasius in using the German language, which he prepared in

a most praiseworthy manner for the expression of philosophical ideas and

furnished with a large part of the technical terms current to-day. Thus

the terms _Verhältniss_ (relation), _Vorstellung_ (representation, idea),

_Bewusstsein_ (consciousness), _stetig (continuus)_, come from Wolff, as

well as the distinction between _Kraft_ (power) and _Vermögen_ (faculty),

and between _Grund_ (ground) and _Ursache_ (cause),[2] Another great

service consisted in the reduction of the philosophy of Leibnitz to a

systematic form, by which he secured a dissemination for it which otherwise

it would scarcely have obtained. But he did not possess sufficient

originality to contribute anything remarkable of his own, and it showed

little self-knowledge when he became indignant at the designation

Leibnitzio-Wolffian philosophy, which was first used by his pupil,

Bilfinger. The alterations which he made in the doctrines of Leibnitz are

far from being improvements, and the parts which he rejected are just the

most characteristic and thoughtful of all. Such at least is the opinion

of thinkers to-day, though this mutilation and leveling down of the most

daring of Leibnitz's hypotheses was perhaps entirely advantageous for

Wolff's impression on his contemporaries; what appeared questionable to him

would no doubt have repelled them also. Leibnitz's two leading ideas, the

theory of monads and the pre-established harmony, were most of all affected

by this process of toning down. Wolff weakens the former by attributing

a representative power only to actual souls, which are capable of

consciousness, although he holds that bodies are compounded of simple

beings and that the latter are endowed with (a not further defined) force.

He limits the application of the pre-established harmony to the relation of

body and soul, which to Leibnitz was only a case especially favorable for

the illustration of the hypothesis. By such trifling the real meaning of

both these ideas is sacrificed and their bloom rubbed off.--While depth

is lacking in Wolff's thinking, he is remarkable for his power of

systematization, his persevering diligence, and his logical earnestness,

so that the praise bestowed on him by Kant, that he was the author of the

spirit of thoroughness in Germany, was well deserved. He, too, finds

the end of philosophy in the enlightenment of the understanding, the

improvement of the heart, and, ultimately, in the promotion of the

happiness of mankind. But while Thomasius demanded as a condition of such

universal intelligibility and usefulness that, discarding the scholastic

garb, philosophy should appear in the form of easy ratiocination, Wolff, on

the other hand, regards methodical procedure and certainty in results as

indispensable to its usefulness, and, in order to this certainty,

insists on distinctness of conception and cogency of proof. He demands

a _philosophia et certa et utilis_. If, finally, his methodical

deliberateness, especially in his later works, leads him into wearisome

diffuseness, this pedantry is made good by his genuinely German, honest

spirit, which manifests itself agreeably in his judgment on practical

questions.

[Footnote 1: _Reasonable Thoughts on the Powers of the Human

Understanding_, 1712; _Reasonable Thoughts on God, the World, and the

Soul of Man, also on All Things in General_, 1719 (_Notes_ to this 1724);

_Reasonable Thoughts on the Conduct of Man_, 1720; _Reasonable Thoughts on

the Social Life of Man_, 1721; _Reasonable Thoughts on the Operations of

Nature_, 1723; _Reasonable Thoughts on the Purposes of Natural Things_,

1724; _Reasonable Thoughts on the Parts of Man, Animals, and Plants_, 1725,

all in German. Besides these there are extensive Latin treatises (1728-53)

on Logic, Ontology, Cosmology, Empirical and Rational Psychology, Natural

Theology, and all branches of Practical Philosophy. Detailed extracts may

be found in Erdmann's _Versuch einer wissenschaftlichen Darstellung_, ii.

2. The best account of the Wolffian philosophy has been given by Zeller

(pp. 211-273).]

[Footnote 2: Eucken, _Geschichte der Terminologie_^ pp. 133-134.]

Wolff reaches his division of the sciences by combining the two

psychological antitheses--the higher (rational) and lower (sensuous)

faculties of cognition and appetition. On the first is based the

distinction between the rational and the empirical or historical method of

treatment. The latter concerns itself with the actual, the former with the

possible and necessary, or the grounds of the actual; the one observes and

describes, the other deduces. The antithesis of cognition and appetition

gives the basis for the division into theoretical and practical philosophy.

The former, called metaphysics, is divided into a general part, which

treats of being in general whether it be of a corporeal or a spiritual

nature, and three special parts, according to their principal subjects, the

world, the soul, and God,--hence into ontology, cosmology, psychology, and

theology. The science which establishes rules for action and regards man as

an individual being, as a citizen, and as the head or member of a family,

is divided (after Aristotle) into ethics, politics, and economics, which

are preceded by practical philosophy in general, and by natural law. The

introduction to the two principal parts is furnished by formal logic.

Philosophy is the science of the possible, _i.e._, of that which contains

no contradiction; it is science from concepts, its principle, the law of

identity, its form, demonstration, and its instrument, analysis, which in

the predicate explicates the determinations contained in the concept of the

subject. In order to confirm that which has been deduced from pure concepts

by the facts of experience, _psychologia rationalis_ is supplemented by

_psychologia empirica_, rational cosmology by empirical physics, and

speculative theology by an experimental doctrine of God (teleology). Wolff

gives no explanation how it comes about that the deliverances of the

reason agree so beautifully with the facts of experience; in his naïve,

unquestioning belief in the infallibility of the reason he is a typical

dogmatist.

A closer examination of the Wolffian philosophy seems unnecessary, since

its most essential portions have already been discussed under Leibnitz and

since it will be necessary to recur to certain points in our chapter on

Kant. Therefore, referring the reader to the detailed accounts in Erdmann

and Zeller, we shall only note that Wolff's ethics opposes the principle

of perfection to the English principle of happiness (that is good which

perfects man's condition, and this is life in conformity with nature or

reason, with which happiness is necessarily connected); that he makes the

will determined by the understanding, and assigns ignorance as the cause of

sin; that his philosophy of religion, which argues for a natural religion

in addition to revealed religion (experiential and rational proofs for the

existence of God, and a deduction of his attributes), and sets up certain

tests for the genuineness of revelation, favors a rationalism which was

flexible enough to allow his pupils either to take part in orthodox

movements or to advance to a deism hostile to the Church.

Among the followers of Wolff, Alexander Baumgarten (1714-62) deserves

the first place, as the founder of German aesthetics _(Aesthetica_, 1750

_seq_.). He perceives a gap in the system of the philosophical sciences.

This contains in ethics a guide to right volition, and in logic a guide

to correct thinking, but there are no directions for correct feeling, no

aesthetic. The beautiful would form the subject of this discipline. For the

perfection (the harmonious unity of a manifold, which is pleasant to the

spectator), which manifests itself to the will as the good and to the

clear thinking of the understanding as the true, appears--according to

Leibnitz--to confused sensuous perception as beauty. From this on the name

aesthetics was established for the theory of the beautiful, though in

Kant's great work it is used in its literal meaning as the doctrine of

sense, of the faculty of sensations or intuitions. Baumgarten's pupils

and followers, the aesthetic writer G.F. Meier at Halle, Baumeister, and

others, contributed like himself to the dissemination of the Wolffian

system by their manuals on different branches of philosophy. To this school

belong also the following: Thümmig (_Institutiones Philosophia Wolfianae_,

1725-26); the theologian Siegmund Baumgarten at Halle, the elder brother

of the aesthete; the mathematician Martin Knutzen, Kant's teacher;[1] the

literary historian Gottsched [2] at Leipsic; and G. Ploucquet, who in

his _Methodus Calculandi in Logicis_, with a _Commentatio de Arte

Characteristica Universali_ appended to his _Principia de Substantiis et

Phaenomenis_, 1753, took up again Leibnitz's cherished plan for a logical

calculus and a universal symbolic language. The psychologist Kasimir von

Creuz (_Essay on the Soul_, in two parts, 1753-54), and J.H. Lambert,[3]

whom Kant deemed worthy of a detailed correspondence, take up a more

independent position, both demanding that the Wolffian rationalism be

supplemented by the empiricism of Locke, and the latter, moreover, in

anticipation of the Critique of Reason, pointing very definitely to the

distinction between content and form as the salient point in the theory of

knowledge.

[Footnote 3: Lambert: _Cosmological Letters_, 1761; _New Organon_, 1764;

_Groundwork of Architectonics_, 1771. Bernoulli edited some of Lambert's

papers and his correspondence.]

Among the opponents of the Wolffian philosophy, all of whom favor

eclecticism, A. Rüdiger[1] and Chr. Aug. Crusius,[2] who was influenced by

Rüdiger, and, like him, a professor at Leipsic, are the most important.

Rüdiger divides philosophy according to its objects, "wisdom, justice,

prudence," into three parts--the science of nature (which must avoid

one-sided mechanical views, and employ ether, air, and spirit as principles

of explanation); the science of duty (which, as metaphysics, treats of

duties toward God, as natural law, of duties to our neighbor, and deduces

both from the primary duty of obedience to the will of God); and the

science of the good (in which Rüdiger follows the treatise of the Spaniard,

Gracian, on practical wisdom). Crusius agrees with Rüdiger that mathematics

is the science of the possible, and philosophy the science of the actual,

and that the latter, instead of imitating to its own disadvantage the

deductive-analytical method of geometry, must, with the aid of experience

and with attention to the probability of its conclusions, rise to the

highest principles synthetically. Besides its deduction the determinism

of the Wolffian philosophy gave offense, for it was believed to endanger

morals, justice, and religion. The will, the special fundamental power of

the soul (consisting of the impulses to perfection, love, and knowledge),

is far from being determined by ideas; it is rather they which depend on

the will. The application of the principle of sufficient reason, which is

wrongly held to admit of no exception, must be restricted in favor of

freedom. For the rest, we may note concerning Crusius that he derives the

principle of sufficient reason (everything which is now, and before was

not, has a cause) and the principle of contingency from the principles of

contradiction, inseparability, and incompatibility, and these latter from

the principle of conceivability; that he rejects the ontological argument,

and makes the ground of obligation in morality consist in obedience toward

God, and its content in perfection. Among the other opponents of the

Wolffian philosophy, we may mention the theologian Budde(us)[3]

_(Institutiones Philosophiae Eclecticae_, 1705); Darjes (who taught in Jena

and Frankfort-on-the-Oder; _The Way to Truth_, 1755); and Crousaz (1744).

Sensione_, 1704; _Philosophia Synthetica_, 1707; _Physica Divina_, 1716;

ethics), 1744; _A Sketch of the Necessary Truths of Reason_, 1745; _Way to

the Certainty and Trustworthiness of Human Knowledge_, 1747.]

[Footnote 3: J.J. Brucker _(Historia Critica Philosophiae_, 5 vols.,

1742-44; 2d ed., 6 vols., 1766-67) was a pupil of Budde.]

%3. The Illumination as Scientific and as Popular Philosophy.%

After a demand for the union of Leibnitz and Locke, of rationalism and

empiricism, had been raised within the Wolffian school itself, and still

more directly in the camp of its opponents, under the increasing influence

of the empirical philosophy of England,[1] eclecticism in the spirit of

Thomasius took full possession of the stage in the Illumination period.

There was the less hesitation in combining principles derived from entirely

different postulates without regard to their systematic connection, as

the interest in scholastic investigation gave place more and more to the

interest in practical and reassuring results. Metaphysics, noëtics, and

natural philosophy were laid aside as useless subtleties, and, as in the

period succeeding Aristotle, man as an individual and whatever directly

relates to his welfare--the constitution of his inner nature, his duties,

the immortality of the soul, and the existence of God--became the exclusive

subjects of reflection. The fact that, besides ethics and religion,

psychology was chosen as a favorite field, is in complete harmony with the

general temper of an age for which self-observation and the enjoyment of

tender and elevated feelings in long, delightfully friendly letters and

sentimental diaries had become a favorite habit. Hand in hand with this

narrowing of the content of philosophy went a change in the form of

presentation. As thinkers now addressed themselves to all cultivated

people, intelligibility and agreeableness were made the prime requisites;

the style became light and flowing, the method of treatment facile and

often superficial. This is true not only of the popular philosophers

proper--who, as Windelband pertinently remarks (vol. i. p. 563), did not

seek after the truth, but believed that they already possessed it, and

desired only to disseminate it; who did not aim at the promotion of

investigation, but the instruction of the public--but to a certain extent,

also, of those who were conscious of laboring in the service of science.

Among the representatives of the more polite tendency belong, Moses

Mendelssohn[2] (1729-86); Thomas Abbt (_On Death for the Fatherland_, 1761;

_On Merit_, 1765); J.J. Engel (_The philosopher for the World_, 1775); G.S.

Steinbart (_The Christian Doctrine of Happiness_, 1778); Ernst Platner

(_Philosophical Aphorisms_, 1776, 1782; on Platner cf. M. Heinze, 1880);

G.C. Lichtenberg (died 1799; _Miscellaneous Writings_, 1800 _seq_.; a

selection is given in _Reclam's Bibliothek_); Christian Garve (died 1798;

_Essays_, 1792 _seq.; Translations from the Ethical Works of Aristotle,

Cicero, and Ferguson_); and Friedrich Nicolai[3] (died 1811). Eberhard,

Feder, and Meiners will be mentioned later among the opponents of the

Kantian philosophy.

philosophy of the eighteenth century is discussed by Gustav Zart, 1881.]

the Existence of God_, 1785; _To the Friends of Lessing_ (against Jacobi),

the Most Recent German Literature_, from 1759; _Universal German Library_,

Among the psychologists J.N. Tetens, whose _Philosophical Essays on Human

Nature_, 1776-77, show a remarkable similarity to the views of Kant,[1]

takes the first rank. The two thinkers evidently influenced each other. The

three fold division of the activities of the soul, "knowing, feeling,

and willing," which has now become popular and which appears to us

self-evident, is to be referred to Tetens, from whom Kant took it; in

opposition to the twofold division of Aristotle and Wolff into "cognition

and appetition," he established the equal rights of the faculty of

feeling--which had previously been defended by Sulzer (1751), the aesthetic

writer, and by Mendelssohn (1755, 1763, 1785). Besides Tetens, the

following should be mentioned among the psychologists: Tetens's opponent,

Johann Lossius (1775), an adherent of Bonnet; D. Tiedemann (_Inquiries

concerning Man_, from 1777), who was estimable also as a historian of

philosophy (_Spirit of Speculative Philosophy_, 1791-97); Von Irwing

(1772 _seq_.; 2d ed., 1777); and K. Ph. Moriz (_Magazin zur

Erfahrungsseelenlehre_, from 1785). Basedow (died 1790), Campe (died 1818),

and J.H. Pestalozzi (1745-1827) did valuable work in pedagogics.

[Footnote 1: Sensation gives the content, and the understanding

spontaneously produces the form, of knowledge. The only objectivity of

knowledge which we can attain consists in the subjective necessity of the

forms of thought or the ideas of relation. Perception enables us to cognize

phenomena only, not the true essence of things and of ourselves, etc.]

One of the clearest and most acute minds among the philosophers of the

Illumination was the deist Hermann Samuel Reimarus[1] (1694-1768), from

1728 professor in Hamburg. He attacks atheism, in whatever form it may

present itself, with as much zeal and conviction as he shows in breaking

down the belief in revelation by his inexorable criticism (in his

_Defense_, communicated in manuscript to a few friends only). He obtains

his weapons for this double battle from the Wolffian philosophy. The

existence of an extramundane deity is proved by the purposive arrangement

of the world, especially of organisms, which aims at the good--not merely

of man, as the majority of the physico-theologists have believed, but--of

all living creatures. To believe in a special revelation, _i.e._, a

miracle, in addition to such a revelation of God as this, which is granted

to all men, and is alone necessary to salvation, is to deny the perfection

of God, and to do violence to the immutability of his providence. To these

general considerations against the credibility of positive revelation

are to be added, as special arguments against the Jewish and Christian

revelations, the untrustworthiness of human testimony in general, the

contradictions in the biblical writings, the uncertainty of their meaning,

and the moral character of the persons regarded as messengers of God, whose

teachings, precepts, and deeds in no wise correspond to their high mission.

Jewish history is a "tissue of sheer follies, shameful deeds, deceptions,

and cruelties, the chief motives of which were self-interest and lust for

power." The New Testament is also the work of man; all talk of divine

inspiration, an idle delusion, the resurrection of Christ, a fabrication of

the disciples; and the Protestant system, with its dogmas of the Trinity,

the fall of man, original sin, the incarnation, vicarious atonement, and

eternal punishment, contrary to reason. The advance of Reimarus beyond

Wolff consists in the consistent application of the criteria for the divine

character of revelation, which Wolff had set up without making a positive,

not to speak of a negative, use of them. His weakness[2] consists in the

fact that, on the one hand, he contented himself with a rationalistic

interpretation of the biblical narratives, instead of pushing on--as Semler

did after him at Halle (1725-91)--to a historical criticism of the sources,

and, on the other, held fast to the alternative common to all the deists,

"Either divine or human, either an actual event or a fabrication," without

any suspicion of that great intermediate region of religious myth, of the

involuntary and pregnant inventions of the popular fancy.

[Footnote 1: H.S. Reimarus: _Discussions on the Chief Truths of Natural

Religion_, 1754; _General Consideration of the Instincts of Animals_, 1762;

_Apology or Defense for the Rational Worshipers of God_. Fragments of the

last of these works, which was kept secret during its author's life, were

published by Lessing (the well-known "Wolffenbüttel Fragments," from

1774). A detailed table of contents is to be found in _Reimarus und seine

Schutzschrift_, 1862, by D. Fr. Strauss, included in the fifth volume of

his _Gesammelte Schriften_.]

[Footnote 2: Cf. O. Pfleiderer, _Philosophy of Religion_, vol. i. p. 102,

p. 106 _seq_.]

The philosophico-religious standpoint of G.E. Lessing (1729-81), in whom

the Illumination reached its best fruitage, was less one-sided. Apart from

the important aesthetic impulses which flowed from the _Laocoon_ (1766) and

the _Hamburg Dramaturgy_ (1767-69), his philosophical significance rests

on two ideas, which have had important consequences for the religious

conceptions of the nineteenth century: the speculative interpretation of

certain dogmas (the Trinity, etc.), and the application of the Leibnitzian

idea of development to the history of the positive religions. By both of

these he prepared the way for Hegel. In regard to his relation to his

predecessors, Lessing sought to mediate between the pantheism of Spinoza

and the individualism of Leibnitz; and in his comprehension of the latter

showed himself far superior to the Wolffians. He can be called a Spinozist

only by those who, like Jacobi, have this title ready for everyone

who expresses himself against a transcendent, personal God, and the

unconditional freedom of the will. Moreover, in view of his critical and

dialectical, rather than systematic, method of thinking, we must guard

against laying too great stress on isolated statements by him.[1]

[Footnote 1: A caution which Gideon Spicker (_Lessings Weltanschauung_,

1883) counsels us not to forget, even in view of the oft cited avowal of

determinism, "I thank God that I must, and that I must the best." Among the

numerous treatises on Lessing we may note those by G.E. Schwarz (1854), and

Zeller (in Sybel's _Historische Zeitschrift_, 1870, incorporated in the

second collection of Zeller's _Vorträge und Abhandlungen_, 1877); and on

his theological position, that of K. Fischer on Lessing's _Nathan der

Weise_, 1864, as well as J.H. Witte's _Philosophie unserer Dichterheroen_,

vol. i. _(Lessing and Herder_), 1880. [Cf. in English, Sime, 2 vols., 1877,

and _Encyclopedia Britannica_, vol. xiv. pp, 478-482.--TR.]]

Lessing conceives the Deity as the supreme, all-comprehensive, living

unity, which excludes neither a certain kind of plurality nor even a

certain kind of change; without life and action, without the experience of

changing states, the life of God would be miserably wearisome. Things are

not out of, but in him; nevertheless (as "contingent") they are distinct

from him. The Trinity must be understood in the sense of immanent

distinctions. God has conceived himself, or his perfections, in a twofold

manner: he conceived them as united and himself as their sum, and he

conceived them as single. Now God's thinking is creation, his ideas

actualities. By conceiving his perfections united he created his eternal

image, the Son of God; the bond between God representing and God

represented, between Father and Son, is the Holy Spirit. But when he

conceived his perfections singly he created the world, in which these

manifest themselves divided among a continuous series of particular beings.

Every individual is an isolated divine perfection; the things in the world

are limited gods, all living, all with souls, and of a spiritual nature,

though in different degrees. Development is everywhere; at present the soul

has five senses, but very probably it once had less than five, and in

the future it will have more. At first the actions of men were guided by

obscure instinct; gradually the reason obtained influence over the will,

and one day will govern it completely through its clear and distinct

cognitions. Thus freedom is attained in the course of history--the rational

and virtuous man consciously obeys the divine order of the world, while he

who is unfree obeys unconsciously.

Lessing shares with the deistic Illumination the belief in a religion of

reason, whose basis and essential content are formed by morality; but he

rises far above this level in that he regards the religion of reason not

as the beginning but as the goal of the development, and the positive

religions as necessary transition stages in its attainment. As natural

religion differs in each individual according to his feelings and powers,

without positive enactments there would be no unity and community in

religious matters. Nevertheless the statutory and historical element is

not a graft from without, but a shell organically grown around natural

religion, indispensable for its development, and to be removed but

gradually and by layers--when the inclosed kernel has become ripe and firm.

The history of religions is an _education of the human race through divine

revelation_; so teaches his small but thoughtful treatise of 1780.[1] As

the education of the individual man puts nothing extraneous into him, but

only gives him more quickly and easily that which he could have reached of

himself, so human reason is illuminated by revelation concerning things

to which it could have itself attained, only that without God's help the

process would have been longer and more difficult--perhaps it would have

wandered about for many millions of years in the errors of polytheism, if

God had not been pleased by a single stroke (his revelation to Moses) to

give it a better direction. And as the teacher does not impart everything

to the pupil at once, but considers the state of development reached by him

at each given period, so God in his revelation observes a certain order and

measure. To the rude Jewish people he revealed himself first as a national

God, as the God of their fathers; they had to wait for the Persians to

teach them that the God whom they had hitherto worshiped as the most

powerful among other gods was the only one. Although this lowest stage in

the development of religion lacked the belief in immortality, yet it must

not be lightly valued; let us acknowledge that it was an heroic obedience

for men to observe the laws of God simply because they are the laws of God,

and not because of temporal or future rewards! The first practical teacher

of immortality was Christ; with him the second age of religion begins: the

first good book of elementary instruction, the Old Testament, from which

man had hitherto learned, was followed by the second, better one, the New

Testament. As we now can dispense with the first primer in regard to the

doctrine of the unity of God, and as we gradually begin to be able to

dispense with the second in regard to the doctrine of the immortality of

the soul, so this New Testament may easily contain still further truths,

which for the present we wonder at as revelations, until the reason shall

learn to derive them from other truths already established. Lessing himself

makes an attempt at a philosophical interpretation of the dogmas of the

Trinity (see above), of original sin, and of atonement. Such an advance

from faith to knowledge, such a development of revealed truths into proved

truths of reason, is absolutely necessary. We cannot dispense with the

truths of revelation, but we must not remain content with simply believing

them, but must endeavor to comprehend them; for they have been revealed in

order that they may become rational. They are, as it were, the sum which

the teacher of arithmetic tells his pupils beforehand so that they

may guide themselves by it; but if they content themselves with this

solution--which was given merely as a guide--they would never learn to

calculate. Hand in hand with the advance of the understanding goes the

progress of the will. Future recompenses, which the New Testament promises

as rewards of virtue, are means of education, and will gradually fall into

disuse: in the highest stage, the stage of purity of heart, virtue will

be loved and practiced for its own sake, and no longer for the sake of

heavenly rewards. Slowly but surely, along devious paths which are yet

salutary, we are being led toward that great goal. It will surely come, the

time of consummation, when man will do the good because it is good, this

time of the new, eternal Gospel, this third age, this "Christianity of

reason." Continue, Eternal Providence, thine imperceptible march; let me

not despair of thee because it is imperceptible, not even when to me thy

steps seem to lead backward. It is not true that the straight line is

always the shortest.

[Footnote 1: _Die Erziehung des Menschengeschlects_.]

With the thought that every individual must traverse the same course as

that by which the race attains its perfection, Lessing connects the idea

of the transmigration of souls. Why may not the individual man have been

present in this world more than once? Is this hypothesis so ridiculous

because it is the oldest?

If Lessing abandoned the ranks of the deists by his recognition of the

fact that the positive religions contain truth in a gradual process of

purification, by his free criticism, on the other hand, he broke with

the orthodox, whose idolatrous reverence for the Bible was to him an

abomination. The letter is not the spirit, the Bible is not religion, nor

yet its foundation, but only its records. Contingent historical truths can

never serve as a proof of the necessary truths of reason. Christianity is

older than the New Testament.

Already, in the case of Lessing, we may doubt, in view of his historical

temper and of certain speculative tendencies, whether he is to be included

among the Illuminati. In the case of Kant a decided protest must be

raised against such a classification. When Hegel numbers him among the

philosophers of the Illumination, on account of his lack of rational

intuition, and some theologians on account of his religious rationalism,

the answer to the former is that Kant did not lack the speculative gift,

but only that it was surpassed by his gift of reflection, and, to the

latter, that in regard to the positive element in religion he judged very

differently from the deists and appreciated the historical element more

justly than they--if not to the same extent as Lessing and Herder. We

do not need to lay great stress on the fact that Kant had a lively

consciousness that he was making a contribution to thought, and that the

Illumination contemplated this new doctrine without comprehending it, in

order to recognize that the difference between his efforts and achievements

and those of the Illumination is far greater than their kinship. For

although Kant is upon common ground with it, in so far as he adheres to its

motto, "Have courage to use thine own understanding, become a man, cease

to trust thyself to the guidance of others, and free thyself in all fields

from the yoke of authority," and, although besides such formal injunctions

to freedom of thought, he also shares in certain material tendencies and

convictions (the turning from the world to man, the attempt at a synthesis

of reason and experience, and the belief in a religion of reason); yet in

method and results, he stands like a giant among a race of dwarfs, like one

instructed, who judges from principles, among men of opinion, who merely

stick results together, a methodical systematizer among well-meaning but

impotent eclectics. The philosophy of the Illumination is related to

that of Kant as argument to science, as halting mediation to principiant

resolution, as patchwork to creation out of full resources, yet at the same

time as wish to deed and as negative preparation to positive achievement.

It was undeniably of great value to the Kantian criticism that the

Illumination had created a point of intersection for the various tendencies

of thought, and had brought about the approximation and mutual contact of

the opposing systems which then existed, while, at the same time, it had

crumbled them to pieces, and thus awakened the need for a new, more firmly

and more deeply founded system.

%4. The Faith Philosophy.%

The philosophers of feeling or faith stand in the same relation to the

German Illumination as Rousseau to the French. Here also the rights of

feeling are vindicated against those of the knowing reason. Among the

distinguished representatives of this anti-rationalistic tendency Hamann

led the way, Herder was the most prolific, and Jacobi the clearest. That

the fountain of certitude is to be sought not in discriminating thought,

but in intuition, experience, revelation, and tradition; that the highest

truths can be felt only and not proved; that all existing things are

incomprehensible, because individual--these are convictions which, before

Jacobi defended them as based on scientific principles, had been vehemently

proclaimed by that singular man, J.G. Hamann (died 1788) of Königsberg.

From an unprinted review by Hamann, Herder drew the objections which his

"Metacritique" raises against Kant's Critique of Reason--that the division

of matter and form, of sensibility and understanding, is inadmissible;

that Kant misunderstood the significance of language, which is just where

sensibility and understanding unite, etc.

In Herder[1] (1744-1803: after 1776 Superintendent-General in Weimar) the

philosophy of feeling gained a finer, more perspicuous and harmonious

nature, who shared Lessing's interest in history and his tendency to

hold fast equally to pantheism and to individualism. God is the all-one,

infinite, spiritual (non-personal) primal force, which wholly reveals

itself in each thing _(God: Dialogues on the System of Spinoza_, 1787).

To the life, power, wisdom, and goodness of God correspond the life and

perfection of the universe and of individual creatures, each of which

possesses its own irreplaceable value and bears in itself its future in

germ. Everywhere, one and the same life in an ascending series of powers

and forms with imperceptible transitions. Always, an inner and an outer

together; no power without organ, no spirit without a body. As thought is

only a higher stage of sensation, which develops from the lower by means of

language--reason, like sense, is not a productive but a receptive faculty

of knowing, perceiving ("_Vernehmen_")--so the free process of history is

only the continuation and completion of the nature-process (_Ideas for the

Philosophy of the History of Mankind_, 1784 _seq_.). Man, the last child of

nature and her first freedman, is the nodal point where the physical series

of events changes into the ethical; the last member of the organisms of

earth is at the same time the first in the spiritual development. The

mission of history is the unfolding of all the powers which nature

has concentrated in man as the compendium of the world; its law, that

everywhere on our earth everything be realized that can be realized there;

its end, humanity and the harmonious development of all our capacities. As

nature forms a single great organism, and from the stone to man describes

a connected development, so humanity is a one great individual which passes

through its several ages, from infancy (the Orient), through boyhood

(Eygpt and Phoenicia), youth (Greece), and manhood (Rome), to old age (the

Christian world). The spirit stands in the closest dependence upon nature,

and nature is concerned in history throughout. The finer organization of

his brain, the possession of hands, above all, his erect position, make

man, man and endow him with reason. Similarly it is natural conditions,

climate, the character of the soil, the surrounding animal and vegetable

life, etc., that play an essential part in determining the manners, the

characters, and the destinies of nations. The connection of nature with

history by means of the concept of development and through the idea that

the two merely represent different stages of the same fundamental process,

made Herder the forerunner of Schelling.

[Footnote 1: On Herder cf. the biography by R. Haym, 2 vols., 1877, 1885;

and the work by Witte which has been referred to above (p. 306, note).]

His polemic against Kant in the _Metacritique_, 1799 (against the _Critique

of Pure Reason_), and the dialogue _Calligone_, 1800 (against the _Critique

of Judgment_), is less pleasing. These are neither dignified in tone nor

essentially of much importance. In the former the distinction between

sensibility and reason is censured, and in the latter the separation of the

beautiful from the true and the good, but Kant's theory of aesthetics is

for the most part grossly misunderstood. The "disinterested" satisfaction

Herder makes a cold satisfaction; the harmonious activity of the cognitive

powers, a tedious, apish sport; the satisfaction "without a concept,"

judgment without ground or cause. The positive elements in his own views

are more valuable. Pleasure in mere form, without a concept, and without

the idea of an end, is impossible. All beauty must mean or express

something, must be a symbol of inner life; its ground is perfection or

adaptation. Beauty is that symmetrical union of the parts of a being, in

virtue of which it feels well itself and gives pleasure to the observer,

who sympathetically shares in this well-being. The charm and value of the

_Calligone_ lie more in the warmth and clearness with which the expressive

beauty of single natural phenomena is described than in the abstract

discussion.

Friedrich Heinrich Jacobi (1743-1819) gave the most detailed statement of

the position of the philosophy of feeling, and the most careful proof of

it. He was born in Düsseldorf, the son of a manufacturer; until 1794 he

lived in his native place and at his country residence in Pempelfort; later

he resided in Holstein, and, from 1805, in Munich, where, in 1807-13, he

was president of the Academy of Sciences. Of his works, collected in five

volumes, 1812-25, we are here chiefly concerned with the letters _On the

Doctrine of Spinoza_, 1785; _David Hume on Faith, or Idealism and Realism_,

1787; and the treatise _On Divine Things_, 1811, which called out

Schelling's merciless response, _Memorial of Jacobi_. Besides Hume and

Spinoza, the sensationalism of Bonnet and the criticism of Kant had made

the most lasting impression on Jacobi. His relation to Kant is neither that

of an opponent nor of a supporter and popularizer. He declares himself in

accord with Kant's critique of the understanding (the understanding is

merely a formal function, one which forms and combines concepts only, but

does not guarantee reality, one to which the material of thought must be

given from elsewhere and for which the suprasensible remains unattainable);

in regard to the critique of reason he raises the objection that it; makes

the Ideas mere postulates, which possess no guarantee for their reality.

The critique of sensibility appears to him still more unsatisfactory, as

it does not explain the origin of sensations. Without the concept of the

"thing-in-itself" one cannot enter the Kantian philosophy, and with it

one cannot remain there. Fichte has drawn the correct conclusion from the

Kantian premises; idealism is the unavoidable result of the Critique of

Reason and foretold by; it as the Messiah was foretold by John the Baptist.

And by the evil fruit we know the evil root: the idealistic theory is

philosophical nihilism, for it denies the reality of the external world, as

the materialism of Spinoza denies a transcendent God and the freedom of

the will. Reality slips away from both these systems--they are the only

consistent ones there are--material reality escaping from the former

and suprasensible reality from the latter; and this must be so, because

reality, of whatever kind it be, cannot be known, but only believed and

felt. The actual, the existence of the noumenal as well as of the external

world, even the existence of our own body, makes itself known to us through

revelation alone; the understanding comprehends relations only; the

certainty that a thing exists is attained only through experience and

faith. Sense and reason are the organs of faith, and hence the true

sources of knowledge; the former apprehends the natural, the latter, the

supernatural, while for the understanding is left only the analysis and

combination of given intuitions.

Philosophy as a science from concepts must necessarily prove atheistic and

fatalistic. Conception and proof mean deduction from conditions. How shall

that which has no cause from which to explain it, the unconditioned, God,

and freedom, be comprehended and proved? Demonstration rises along the

chain of causes to the universe alone, not to a transcendent Creator;

mediate knowledge is confined to the sphere of conditioned being and

mechanical becoming. The intuitive knowledge of feeling alone leads us

beyond this, and along with the wonderful, the inconceivable power of

freedom in ourselves, which is above all nature, shows us the primal source

of all wonders, the transcendent God above us. The inference from our

own spiritual, self-conscious, free personality to that of God is no

unauthorized anthropomorphism--in the knowledge of God we may fearlessly

deify our human existence, because God, when he created man, gave his

divine nature human form. Reason and freedom are the same: the former

is theoretical, the latter practical elevation to the suprasensible.

Nevertheless virtue is not based upon an inflexible, despotic, abstractly,

formal law, but upon an instinct, which, however, does not aim at

happiness. Thus Jacobi attempts to mediate between the ethics of the

Illumination and the ethics of Kant, by agreeing with the former in regard

to the origin of virtue (it arises from a natural impulse), and with the

latter in regard to its nature (it consists in disinterestedness). Hence

with the Illumination he rejects the imperative form, and with Kant the

eudemonistic end. At the same time he endeavors to introduce Herder's idea

of individuality into ethics, by demanding that morality assume a special

form in each man. Schiller and the romantic school take from Jacobi their

ideal of the "beautiful soul," which from natural impulse realizes in its

action, and still more in its being, the good in an individual way.
