Historical science is, like philology or psychology, still conceived

in different senses by experts. Very often history is wrongly taken

to mean the record of events that have occurred in the course of the

development of civilized life--the history of peoples and states

(humorously described as "the history of the world"), of civilization,

of morals, etc. This is merely an anthropocentric feeling that in

the strictly scientific sense "history" can only be used for the

record of man's doings. In this sense history is opposed to nature,

the one dealing with the province of morally free phenomena (with

preconceived aim), and the other comprising the province of natural

law (without preconceived aim). As if there were no "natural history,"

or as if cosmogony, geology, ontogeny, and phytogeny were not

historical sciences! Although this dualistic and anthropistic view

still prevails in our universities, and state and Church protect the

venerable tradition, there can be no doubt that sooner or later it

will be replaced by a purely monistic philosophy of history. Modern

anthropogeny shows us the intimate connection between the evolution of

the human individual and that of the race; and by means of prehistoric

and phylogenetic research it joins what is called the history of the

world to the stem-history of the vertebrates.

Medicine belongs to the front rank of practical or applied sciences. In

its long and interesting history it teaches how it is only a monistic

knowledge of nature, not a dualistic notion of revelation, that affords

the foundations of true science and the profitable application of

this to the most important aspects of practical life. Medicine was

originally the business of the priests, and for thousands of years

it was under the influence of mystic and superstitious ideas which

were connected with religious dogmas. However, two thousand years ago

the great physicians of classic antiquity made a serious effort to

provide a solid base for medical practice by a thorough anatomic and

physiological study of the human frame. But in the general reaction

of the Middle Ages superstitious and miraculous ideas once more

defeated independent scientific investigation. Disease was supposed

to be the work of evil spirits (as Christ thought) which had to be

exorcised. Miracles are still thought to take place, even in cultured

circles. I need only mention the wonders of patent medicines, magnetic

cures, Christian Science, and other charlatanry. However, the great

development of science in the nineteenth century, especially the

astonishing advance of biology about the middle of the century,

gradually shaped medicine into the monistic science which assuages so

much pain and suffering in humanity to-day. Pathology, the science

of disease, and therapeutics, the rational science of healing, are

grounded now on the safe methods of physics and chemistry and a

thorough knowledge of the human organism. Disease is no longer regarded

as a special entity that comes on the body like an evil spirit or

mysterious organism, but is conceived as a baneful disturbance of its

normal activity. Pathology is only a branch of physiology; it studies

the changes that take place in the tissues and cells under abnormal and

dangerous conditions. When the causes of these changes are poisons or

foreign organisms (such as bacteria or amœbæ), the art of healing

has to remove them and restore the normal equilibrium of the functions.

The science of mental disease is a special branch of medicine; it has

the same relation to it as psychology has to physiology. However, as

pathological psychology it deserves special consideration, not only

on account of its extreme practical importance, but also because of

its theoretical interest. The misleading dualist idea of body and soul

that has perverted our notions of mental life from the oldest times

has led people to regard mental disorders as special phenomena, at one

time directly as evil spirits that enter from without into the human

body, at another time as mysterious dynamic occurrences affecting the

mystic being of the soul (independently of the body). These dualistic

and still wide-spread and mischievous errors have caused the most

fatal mistakes in the treatment of mental disease; they have had the

most unfortunate effect on juristic and social and other aspects of

practical life. But the ground has been cut from under these irrational

and superstitious ideas by modern psychiatry, which regards all mental

disease as a disorder of the brain, and traces it to changes in the

cortex that lie at the root of all psychoses (delusions, lunacy,

etc.). As we call this central organ of mind the phronema, we may say:

Psychiatry is the pathology and therapeutics of the phronema. In many

disorders we have already succeeded in anatomically and chemically

tracing the changes in the psychic or phronetal cells (the neurona

in the phronema). These acquisitions of the pathological anatomy and

physiology of the phronema have a great philosophic interest, because

they throw a good deal of light on the monistic conception of psychic

life. As the greater part (sixty to ninety per cent.) of these diseases

are hereditary, and they have mostly been acquired gradually by the

ancestors of the patient, they also afford clear proof of progressive

heredity, or the inheritance of acquired characters.

Thousands of years ago, when barbaric races began to adapt themselves

to civilized life, they had a concern for their bodily health and

strength. In classic antiquity the care of the body by baths, gymnastic

exercises, etc., was greatly developed, and connected with religious

ceremonies. The splendid aqueducts and baths of Greece and Rome show

how much importance they attached to the external and internal use of

water. The Middle Ages brought reaction in this province like so many

others. As Christianity depreciated this life and said it was merely a

preparation for the life to come, it led to a disdain of culture and

of nature; and as it regarded man's body only as the temporary prison

of his immortal soul, it attached no importance to the care of it. The

frightful plagues that swept away millions of men in the Middle Ages

were only fought with prayer, processions, and other superstitious

devices, instead of with rational hygienic and sanitary measures. We

have only gradually learned to discard this superstition. It was not

until the second half of the nineteenth century that a sound knowledge

of the physiological functions and environment of the organism induced

people once more to have a concern for bodily culture. All that modern

hygiene now does for the public health, especially the improvement of

the dwellings and food of the poorer classes, the prevention of disease

by healthier habits, baths, athletics, etc., can be traced to the

monistic teaching or reason, and is altogether opposed to the Christian

belief in Providence and the dualism connected therewith. The maxim of

modern hygiene is: God helps those who help themselves.

The remarkable progress of technical science in the nineteenth

century, which has stamped our age as "an age of machinery," is a

direct consequence of the immense advance of theoretical science.

All the privileges and comforts which modern life gives us are due

to scientific discoveries, especially in physics and chemistry.

We need only recall the enormous importance of steam and electric

machinery, modern mining, agriculture, and so on. If by these means

modern industry and international commerce have prospered beyond all

expectations, we owe this to the practical application of empirical

truths. "Mental science" and metaphysical speculation have had nothing

to do with it. There is no need of further proof that all the technical

sciences have a purely monistic character, like their exact sources,

physics and chemistry.

The scientific development of education is one of the greatest tasks

of modern civilization. The ideas that are impressed on the mind in

early youth are most persistent, and generally determine the direction

of thought and conduct for the whole of life. Hence we find the

struggle between the two philosophic tendencies assuming the greatest

practical importance in this department. As the priests were, thousands

of years ago, in the first stages of civilization, the sole trainers

of the growing mind, they had charge of the school as well as of

medicine. Religion was made the chief foundation of instruction, and

its doctrines were the moral guide for the whole of life. The isolated

attempts that were made by monistic philosophy in ancient times to

destroy this theistic superstition had no effect on the education of

the young. In this the dualistic principles of Plato and Aristotle

prevailed, their metaphysical theories being blended with the teaching

of the Church. In the Middle Ages the power of the Roman priesthood

enforced them everywhere. And, although a good deal of this teaching

lost its prestige at the Reformation, the influence of the Church on

the school was maintained down to our own time. The spiritual power of

the Church finds a useful ally in this in the conservative attitude

of most governments. Throne and altar support each other; both dread

the advance of scientific inquiry. In face of this powerful dualistic

alliance, supported by the mental apathy of the masses and a convenient

blind submission to authority, the monistic system has a difficult

position to maintain. It will only gain solid ground in education when

the school is divorced from the Church and scientific knowledge is made

the foundation of the curriculum. I have pointed out in the nineteenth

chapter of the _Riddle_ the guiding principles to be followed in this

reform of education in opposition to the influence of Church and state.

As we have dealt in the eighteenth chapter with morals and their

development from habit and adaptation, we need only mention here the

contradiction that we still find between the monistic claims of pure

reason and the dualistic claims of practical reason. This has been

largely sustained by Kant's teaching, but his categorical imperative

has been completely refuted by modern science. The metaphysical

grounding of morality on free will and ethical intuitions (_a

priori_) must be replaced by a physiological ethic, based on monistic

psychology. As this can no more recognize a moral order of the world

in history than a loving Providence in the life of the individual,

the monistic morality of the future must be reducible to the laws of

biology, and especially of evolution.

The great importance that attaches to the new science of sociology is

due to its close relations to theoretical anthropology and psychology

on the one hand, and to practical politics and law on the other. When

we take it in the wider sense, human sociology joins on to that of

the nearest mammals. The family life, marriage, and care of the young

in the mammals, the formation of herds in the carnivora and ungulates

and of troops in the social apes, lead on to the looser associations

of savages and barbarians, and from these to the beginnings of

civilization. The history of these associations is connected with

the social rules that govern the intercourse of smaller and larger

communities. In the biological reduction of social rules to the natural

laws of heredity and adaptation, dynamic sociology (as Lester Ward

has called it) proceeds on purely monistic lines, while in social

intercourse itself we still find a good deal of dualism. How little

truth and nature count for in our cultured society, how much hypocrisy

and insincerity have to do with social rules, has been well shown by

Max Nordau in his _Conventional Lies of Civilization_.

Politics is closely connected with sociology on the one hand and

law on the other. As internal politics it controls the organization

of the state by a constitution; as external or foreign politics it

directs the relations of states to each other. In my opinion, pure

reason should prevail in both departments; the relations of the

citizens to each other and to the whole should be regulated by the

same ethical principles that we recognize in personal intercourse. We

are, unfortunately, very far from this ideal in the life of a modern

state. Brutal egoism rules in foreign politics; every nation thinks

only of its own advantage, and furthers it with all its military and

other resources. Domestic politics is still largely directed by the

barbaric prejudices of the Middle Ages. Great struggles are in progress

between the central government and the mass of the people. Both parties

spend themselves in fruitless conflicts; yet reason in the life of the

state suffers more than its special political complexion. "Whether the

state shall be a monarchy or a republic, aristocratic or democratic,

are subordinate questions. The great question is: Shall the modern

state be spiritual or secular? Shall it be governed _theocratically_ by

irrational beliefs and clerical arbitrariness, or _nomocratically_ by

rational laws and civic right?" (_Riddle_, chapter i.).

In the science of law, too, we find the prevalence of the dualistic

principles that have come down from the Middle Ages and antiquity, and

have acquired a certain sacredness by blending with the teaching of

the Church. Kant's dualism is again found to be at work, influencing

the ideas of jurists and statesmen. With it we find in our codes many

carefully preserved relics of mediæval superstition. A great deal of

harm is done by this religious influence. Every day we read in the

papers of curious deliverances in the lower and higher courts at which

every thoughtful man can only shake his head. Here also there will be

no solid improvement until the education of jurists includes a thorough

training in anthropology and psychology as well as in the code.

Theology has stood at the head of the four venerable "faculties" at

our universities for centuries. It still holds this place of honor,

as the Church, the organ of practical theology, continues to exercise

a profound influence on life. In fact, most of the other branches

of applied science--especially jurisprudence, politics, ethics, and

pedagogics--are still more or less affected by religious prejudices.

The chief of these is the idea of God conceived in some form or other

as the Supreme Being; as Goethe says, "Every one calls the best he

knows his God." However, the idea of God is not the chief feature

of all religions. The three greatest Asiatic religions--Buddhism,

Brahmanism, and Confucianism--were at first purely atheistic; Buddhism

was at once idealistic and pessimistic, whence Schopenhauer regarded

it as the highest of all religions. On the other hand, belief in a

personal God is the central feature of the three great Mediterranean

religions. This anthropomorphic God is conceived in a hundred forms in

the various sects of the Mosaic, Christian, and Mohammedan religions,

but his existence remains one of the chief articles of faith. No

evidence of his existence is to be found; this was very ably shown by

Kant, although he thought that practical reason postulated it. All that

revelation is supposed to teach us on the matter belongs to the region

of fiction. The whole field of theology, especially dogmatic theology,

and the whole of the Church teaching based on it, are based on

dualistic metaphysics and superstitious traditions. It is no longer a

serious subject of scientific treatment. On the other hand, comparative

religion is a very important branch of theoretical theology. It deals

with the origin, development, and significance of religion on the

basis of modern anthropology, ethnology, psychology, and history. When

we study without prejudice the results of these sciences bearing on

religion, theology turns out to be pantheism, in the sense of Spinoza

and Goethe, and thus monism becomes a connecting link between religion

and science.

This brief survey of the twenty chief branches of modern science

and their relation to monism and dualism shows that we are face to

face with great contradictions, and that we are still far from the

harmonious and successful adjustment of these differences. They are

partly due to a real antinomy of reason in the Kantist sense--an

antithesis in ideas, in which the positive seems to be just as

capable of proof as its contradictory. But, for the most part, this

unfortunate antinomy in the sciences is connected with their historical

development. Pure reason, the highest quality of civilized man, was

gradually evolved from the intelligence of the savage, and this in turn

from the instincts of the apes and lower mammals; and many relics of

its former lower condition remain to-day, and have, through practical

reason, a most prejudicial influence on science. These dualistic

prejudices and irrational dogmas--intellectual residua of the primitive

condition of the race, fossil ideas and rudimentary instincts--still

pervade the whole of modern theology, jurisprudence, politics, ethics,

psychology, and anthropology. If we glance at the whole field of modern

science at the beginning of the twentieth century in this connection,

we can distribute its twenty sections into three groups--rational

(purely monistic), semi-dogmatic (half-monistic), and dogmatic

(predominantly dualistic) disciplines.

The following may be classed as rational or purely monistic sciences,

in which no competent and thoroughly expert representative now admits

dualistic considerations: of the pure or theoretical sciences, physics,

chemistry, mathematics, astronomy, and geology; of the applied or

practical sciences, medicine, hygiene, and technology. On the other

hand, in the semi-dogmatic sciences we still find a mixture of

monistic and dualistic ideas in the appreciation of their aims and

objects, one or the other prevailing according to the party position

or personal training of the individual representative. This is the

case with most of the biological sciences, biology (in the broadest

sense), anthropology, psychology, philology, history, psychiatry;

and of the applied sciences, pedagogics and ethics. The two latter

sciences form a transition to the four purely dogmatic sciences in

which the traditional dualism is still paramount: sociology, politics,

jurisprudence, and theology. In these branches of science mediæval

traditions retain a good deal of their power. Most of their official

representatives cling to prejudices and superstitions of all sorts,

and very slowly and gradually admit the acquisitions of pure reason as

embodied in monistic anthropology and psychology. The intellectual life

was in many respects more advanced at the beginning of the nineteenth

than of the twentieth century.

This classification of the chief branches of knowledge in their

relation to philosophy, the comprehensive science of general truths,

is naturally only a provisional and personal sketch. It is especially

difficult from the circumstance that all the sciences have very complex

relations to each other, and have undergone many changes as to their

aims and subjects in the course of their historical development. I

will only point out that a good deal of science--in fact, the rational

sciences with exact mathematical basis--have now been completely won

over to monism; and in the semi-dogmatic sciences it is gaining ground

from day to day, so that we may hope sooner or later to see the four

dogmatic sciences also, the strong bulwarks of dualism--sociology,

politics, jurisprudence, and theology--succumb to monism. For the

ultimate aim of all the sciences can only be the unity of their

underlying principles, or their harmonious unification by pure reason.

It is now more and more generally acknowledged in educated countries

that a complete reform of our educational curriculum is needed,

both in elementary and secondary schools and at the universities.

The great struggle between two different tendencies assumes larger

proportions every day. On the one hand, most governments, following

their conservative instinct, cling as far as possible to mediæval

traditions, and find support in the dogmatic teaching of theology

and jurisprudence. On the other hand, the representatives of pure

reason seek to get rid of these fetters, and to introduce the

empirical and critical methods of modern science and medicine into

what are called the mental sciences. The opposition between the two

parties is accentuated by their different sociological tendencies.

Liberal humanists claim that the freedom and education of all men is

the aim of progressive evolution, in the conviction that the free

development of the personality of each individual is the surest

guarantee of happiness. To conservative governments this is a matter of

indifference; they look on the individual citizens, in accordance with

the manifold division of labor, merely as so many screws and wheels in

the great organism of the state. The "upper ten thousand" naturally

think of their own welfare first, and desire to keep all higher

education to themselves. But in the light of pure reason the state is

not an end in itself; it is a means to insure the prosperity of the

citizens. To each of these, whatever their condition, the opportunity

should be afforded of acquiring the higher education and developing

their talents. Hence in education we should impart a general outlook

on all the sides of human life. Each should acquire the elements of

science, not only of physics and chemistry, but also of biology and

anthropology. On the other hand, the predominance of the classical

training over modern ought to be restricted. Every student and every

faculty should be occupied with only philosophy and science in the

first sessions, and not take up special studies until afterwards.

At the close of the _Riddle_ I brought out in clear relief the

antagonism between modern monism and traditional dualism, but also

pointed out that

this strenuous opposition may be toned down to a certain degree

on clear and logical reflection--may, indeed, be converted into a

friendly harmony. In a thoroughly logical mind, applying the highest

principles with equal force in the entire field of the cosmos--in

both organic and inorganic nature--the antithetical positions of

theism and pantheism, vitalism and mechanism, approach until they

touch each other. Unfortunately, consecutive thought is a rare

phenomenon in nature.

This conciliatory disposition has grown stronger and stronger in

me. Every year increases my belief that the dualism of Kant and the

prevalent metaphysical school must give way to the monism of Goethe and

the rising pantheistic tendency. In this we do not lose sight of our

ideals. On the contrary, our "realist philosophy of life" teaches us

that they are rooted deep in human nature. While occupying ourselves

with the ideal world in art and poetry, and cultivating the play of

emotion, we persist, nevertheless, in thinking that the real world,

the object of science, can be truly known only by experience and pure

reason. Truth and poetry are then united in the perfect harmony of

monism.

THE END

FOOTNOTES:

[1] The English translation met with almost equal success. Nearly

one hundred thousand copies of the cheap edition have already been

sold.--TRANS.

[2] Further particulars about the relations of the thought-centres to

the sense-centres will be found in the tenth chapter of _The Riddle of

the Universe_.

[3] English readers who are acquainted with Romanes's posthumous

_Thoughts on Religion_ will recognize the justice of this analysis.

Romanes speaks expressly of the acceptance of Christianity entailing

"the sacrifice of his intellect."--TRANS.

[4] This refers almost entirely to Germany. The reader will remember

that, when Lord Kelvin endeavored to make theosophic capital out

of this temporary confusion in German science, he was immediately

silenced by the leading biologists of this country, Professor E.

Ray-Lankester (for zoology), Sir W. T. Thiselton-Dyer (for botany),

and Sir J. Burdon-Sanderson (for physiology), who sharply rejected

vitalism.--TRANS.

[5] The German word _wunder_ corresponds equally to the English

"miracle" and "wonder." It has seemed necessary to translate it

"wonder" in the title of the work, but frequently as "miracle" in this

chapter.--TRANS.

[6] The English reader may usefully be reminded that Professor Loofs,

Haeckel's chief critic, and one of the foremost German theologians,

rejects these articles of the Creed no less than Haeckel does. A glance

at the pertinent articles in the _Encyclopædia Biblica_ will show how

widely theologians now discard these beliefs.--TRANS.

[7] Compare the opinion of the distinguished American psychologist,

Münsterberg "Science opposes to any doctrine of individual immortality

an unbroken and impregnable barrier" (_Psychology and Life_, p.

85).--TRANS.

[8] A translation of the latest edition of the _Anthropogenie_, with

the full number of fresh illustrations (thirty plates and five hundred

and twelve wood-cuts), will be issued very shortly by the Rationalist

Press Association, under the title of _The Evolution of Man_.

[9] I may remind the English reader that the chosen ecclesiastical

champion against Haeckel in this country, the Rev. F. Ballard, made

this extraordinary fallacy the very pith of his "scientific" attack on

monism.--TRANS.

[10] As already stated, it will presently appear in England with the

title, _The Evolution of Man_.--TRANS.

[11] At the moment I translate this, telegrams from Germany announce

that, by the emperor's orders, a number of ladies were excluded from

the opera for not observing this custom.--TRANS.

[12] The English reader will find in this a reply to the foolish notion

which has been circulated that the recent discovery of radioaction

and the composition of the atom from electrons has affected Haeckel's

position. His monism is completely indifferent to changes in the

physicist conception of the nature of matter.--TRANS.

TRANSCRIBER'S NOTES:

--Obvious print and punctuation errors were corrected.

--The large tables at pages 96 and 189 have been splitted into two parts.

--Original work has "CHAPTER I" instead of "CHAPTER VI" at page 121.

Corrected.

--Original work does not have "XI" at the beginning of chapter (page 239).

Added.
