To be sure, the work of Ziehen is very far from supplying all that

the pedagogue needs. We have in this work a vast mass of valuable

observations, which will have to be elaborated in a manner that accords

with the needs of pedagogy, if this science is to derive any material

profit from psychiatry. For the bibliography of this subject we shall

refer the reader to a former correspondence of ours (_The Monist_ II,

103), and select at present for examination one province only,—a province

which is deserving of especial consideration, inasmuch as the phenomena

which occur in it are phenomena which most frequently confront the

pedagogist, and are most likely to be overlooked by the untrained eye.

We refer to the _psychopathic subsidiary phenomena_ of DR. KOCH, by which

expression this author comprises all the psychical irregularities, be

they natural or acquired, affecting the life of the human personality,

which, though not even in the severest cases amounting to actual mental

disorders, yet in the most favorable instances so affect the persons

afflicted that they appear as lacking the full possession of mental

normality and capacity. The second part of Koch’s work, mentioned in _The

Monist_ in the place above cited, has just now appeared. (Ratisbon, 1892,

Otto Maier). Having discussed in the first part of his work inherited

and chronic psychopathic subsidiary phenomena, the author now proceeds

to discuss acquired subsidiary factors, and holds out the prospect of a

third part, on the appearance of which we shall have occasion again to

discuss the entire work from a different point of view. For the present,

only the pedagogic aspect of the question interests us. On many readers,

Koch’s book must have made the impression,—to judge from his concluding

remarks,—that the author shares Lombroso’s point of view, and to very

many pedagogues such a position would be, from the very outset, a bad

recommendation, for it would necessarily, in the very nature of the case,

involve the pedagogue in great embarrassment, in the same way as it has

involved the philosophical jurist. But embarrassment is no reason why

we should close our ears to the truth, and if Lombroso should be right

in all his teachings, pedagogy would also be obliged to accommodate

its doctrines to his. Upon the whole, however, Koch is opposed to him.

Thus when he says: “What I commend Lombroso for is that he has observed

much, has collected rich materials, and has been the source of great

incentives in many directions, and has worked suggestively in many ways;

what I reproach him with is that he has confounded the healthy with

the diseased, and has brought under one and the same category without

sufficient and appropriate tests, psychotic phenomena and phenomena which

are psychopathically merely of a subsidiary order; what I reject is his

theory of degeneration and his peculiar views of philosophy.”

Material, such as Koch and others offer, must first be elaborated

into a pedagogic psychopathology—or better still into a pedagogic

pathopsychology—before pedagogy, as a whole, can assume in this

direction the proper form. Though we consider, now, this preparatory work

as indispensable, we can, nevertheless, not think of denying the value

of works which, without any profession of far-reaching psychological

analysis, put in effective and available form for pedagogy the diseased

phenomena of the mental life of children. The first German work of this

kind, so far as we know, is from the pen of a Leipsic teacher, GUSTAV

SIEGERT, and bears the title _Problematische Kindesnaturen_.[48] This

little work is now followed by a more comprehensive treatise, published

by a Bremen alienist, Dr. SCHOLZ, already known to the readers of _The

Monist_ (II, 104), and bearing the title _Die Characterfehler des Kindes,

eine Erziehungslehre für Schule und Haus_.[49] Such books are valuable

not only for the observations they offer and the isolated explanations

and pedagogic advice they present, but also for the suggestions which the

attentive and psychologically cultivated reader can always receive from

them.

Like Siegert, Scholz principally shows us isolated child-types wherein

diseased qualities play a more or less pronounced rôle. But while the

former’s presentation is somewhat journalistic in style, that of the

latter is more didactic; although this tendency is not an absolutely

rigid one, as the author counts mothers as readers of his book. But

if the form of presentation leads one to infer greater profundity in

Scholz than in Siegert, this is in still higher degree the case with the

arrangement of the material. While Siegert strings his child-pictures

loosely together, Scholz arranges them according to real psychological

points of view, so that (remarkable to say) the faults of children are

discussed, first, in the province of feeling and sentiment, then in

that of representation, and finally in that of volition and action. The

introductory and concluding chapters show, also, that Scholz attempts

to enter more profoundly into the subject than Siegert proposes, and we

cherish the hope that, now that this popular work has appeared, Scholz

will very soon present us with a strictly scientific book, in which he

shall have occasion to deal with some particular points, such as, for

instance, falsehood and unchastity, more comprehensively than was perhaps

possible in a book intended for his present circle of readers.

With respect, now, to all systematic presentations of pedagogy,

psychopathology can, as we have before indicated, never attain in them

its proper position, until the above-mentioned preparatory work has been

completed. But this fact should not preclude one’s calling especial

attention to the importance of this province, at least in some incidental

manner.

In such a work as the _Allgemeine Pädagogik_ of ZILLER,[50] for instance,

the third edition of which has just been published by F. Mattes of

Leipsic, there surely was abundant opportunity to do this—an opportunity

which one might say almost amounted to obligation. For Ziller treats

hereditary and acquired characteristics in great detail, and such

treatment remains necessarily a one-sided one, if abnormal traits are

not considered in it. Ziller, with Herbart, demands that individuality

always be taken as the starting-point. But how many child-individualities

are there, which, in the different periods of their development, may be

regarded as fully normal!

The reason of this omission must be looked for partly in the

circumstance, that Ziller, as well as the new editor of this otherwise

valuable work, belongs to the Herbartian school. If, namely, we

compare the psychological literature of the Herbartian school with the

publications of French, English, and American writers, or even with

the works which in recent times have issued from other philosophical

quarters of Germany, it will be unmistakably seen that the pathological

conditions of the mind have been little considered by the followers of

Herbart. Nor have voices been wanting, that would make Herbart himself

responsible for this error. He did not, they say, sufficiently appreciate

the importance of the pathological phenomena of mind, and his pupils

were in this respect influenced by him. But this reproach will be found,

on close examination, to be untenable. Herbart, it is true, did express

himself repeatedly against the overestimation of “rare and curious

phenomena,” unusual mental states and such things,[51] and his warning

is applicable also to our epoch, which produces many psychological works

in which remarkable things are to be read but which contribute nothing

worth mentioning towards the explanation of even comparatively simple

events. Herbart holds, that the psychology of the normal and ordinary

states should be the first and principal object of scientific attention;

the explanation of much that is extraordinary will then follow. With

regard to this latter point, he remarks very positively: “I do not,

however, wish by this, to gainsay the value of any real psychological

observation. There must be a welcome place in science for every

experience.” It will be seen, therefore, that Herbart is not at all far

from the point of view of Maudsley and other investigators. We find, in

fact, that he mentions repeatedly abnormal mental conditions, and also

systematically treats them, even quoting such celebrated alienists as

Reil and Pinel (_Text-book of Psychology_, §§ 142-149). The probability

is, therefore, that psychopathology would have been properly employed in

Herbart’s psychology, if it had been at all elaborated in his day, and

its influence would through Herbart have been directly felt in pedagogy,

as no pedagogist has made better or more careful use of psychology than

he.

But Herbart’s pupils have done no further work in the province pointed

out by him. It is true, his psychology has been made use of by physicians

like Griesinger and Spielmann, and recently also to some extent by

Krafft-Ebing, but the works of these men have had no influence on the

psychological text-books of the Herbartian school, and consequently the

science has up to the present day exerted no noticeable influence on

pedagogy, either in Waitz, in Stoy, or in Ziller. In other pedagogic

schools, this has, it is true, also been the case; but in these, who make

no pretensions of relying on the teachings of psychology, the sin is

more easily pardoned. But this is not the only respect in which Ziller’s

_Pedagogy_ is not up to the times. Ziller defined pedagogy as the

influences, formed according to ethical points of view, which are brought

to bear on the mind of the pupil, and would not admit influences brought

to bear on the body, in so far as such should enter into the pedagogic

system. This misconception also springs from Ziller’s adherence to the

Herbartian school, which represents, as we well know, a metaphysical

pluralism; but it is in a still higher degree due to the fact, that

in Ziller’s day both the intimate relation between physiological and

psychological processes had not been satisfactorily established, and also

were not sufficiently known to him. If it were otherwise, his pluralism

need by no means have necessarily led him into such one-sidedness, for

this metaphysical pluralism does not exclude a monistic conception of

_phenomena_; even assuming this doctrine, one may say that motion and

feeling are two different but inseparable sides of the same phenomenon.

The “real things” produce by their interaction, simultaneously and of

necessity, both an inner side and an outer; for which reason one of our

foremost psychologists, Volkmann of Volkmar, explicitly terms Herbart’s

psychology monistic (_Text-book of Psychology_, second edition, I, 63).

A psychologico-physiological work, from which the new editor of Ziller’s

_Pedagogy_ might have extracted many valuable things, is the book of

the Italian MOSSO, _On Fatigue_, which has just been translated into

German,[52] and which will excite much attention owing to the present

active discussion of the question of overwork.

Supplementary to this work I will also mention a little tract by DR.

BURGERSTEIN of Vienna, entitled _Die Arbeitskurve einer Schulstunde_.[53]

This tract is a lecture, which the author gave at the Seventh

International Congress for Hygiene and Demography at London, and in

which he seeks to find by statistical methods, the duration of a

“school-period”—a very laboriously composed treatise and one difficult

to read, but possessed of high interest in psychological and pedagogic

respects.

From pedagogy to evolution is but a step, at least it is in Ziller’s

development of Herbart’s ideas. It is true, Ziller has taken a decided

stand against Darwinism, for Ziller works with two contradictory

ideas; but his theory of education possesses points of resemblance

and analogy to the Darwin-Haeckel theory of development. According

to Ziller, each individual passes, also intellectually, through all

the stages of development that mankind at large has passed through,

only in a shorter time; and it is in conformity with such succession

that the order of the various courses of a pedagogical system is to be

arranged. Following Ziller’s precedent, PROFESSOR VAIHINGER, of Halle,

in his treatise _Naturforschung und Schule_ (Science and the Schools),

has taken up the school-reform initiated by Professor Preyer, and has

expressly transferred the fundamental law of biogenesis to pedagogy.

How instruction is to be arranged under this point of view, cannot be

explained in this letter, which is already long enough. We shall simply

remark that the idea has found in Germany a large number of both friends

and opponents.

The opponents have recently been joined by a natural scientist, DR.

HAMANN, professor of zoology in Göttingen, who has just published a

book under the title _Entwicklungslehre und Darwinismus_ (Evolution and

Darwinism),[54] in which he does not combat the theory of evolution

itself, but simply the Darwin-Haeckelian form of that theory, placing

himself in the ranks of His and Hensen. The book appeared almost

simultaneously with the fourth edition of HAECKEL’S _Anthropogeny_,[55]

but the author, nevertheless, in his supplementary remarks, discusses

the “apology” which Haeckel subjoined to his work. Haeckel’s book needs

no recommendation in scientific circles; it will be sufficient to state

that the work has been subjected to essential alterations, but that its

fundamental features have remained the same.

A new psychology, on the Darwinian basis, by Prof. FRITZ SCHULTZE of

Dresden, is now in course of publication, entitled _Vergleichende

Seelenkunde_ (Comparative Psychology[56]). The first part, which treats

of the fundamental principles of physiological psychology, has already

appeared. On the completion of the work we shall have occasion to return

to it.

CRITICISMS AND DISCUSSIONS.

A LETTER FROM MR. HERBERT SPENCER.

_To the Editor of The Monist_:

As I feel it a duty to reserve, for other purposes, the very small

power of work now left to me, I am obliged to decline entering upon

a controversy. I must leave readers to examine for themselves—little

hoping, however, that they will do so.

One point only I wish to note. The use of the expression “forms of

thought,” instead of “forms of intuition,” was simply an inadvertence;

as will be manifest on observing that though I have used the wrong

expression in the note, I have used the right expression in the text

(p. 203), as also throughout my criticism of Kant’s doctrine in _The

Principles of Psychology_, Part VII, Chapter IV, “The Reasonings of

Metaphysicians,” § 399.

HERBERT SPENCER.

LOGIC AS RELATION-LORE.

In the French _Revue Philosophique_, in the August and September 1891

numbers of the same, M. George Mouret has an essay entitled “Mathematical

Equality” in the course of which and as though subsidiary to his

ostensible purpose he discourses upon the topics of relations and

concepts and upon the fundamental elements of logic in general. His essay

is really more important as a contribution to logical doctrine than as a

treatment of mathematical equality.

The scope of his discourse will be seen by reference to his closing

paragraphs in which he sums up what he considers to be the results

achieved by him in his essay. Therein, he says that he has “treated of

the general theory of the composition of concepts and relations and set

the foundations of the logic of analysis and the logic of definition.”

I. THE SPENCERIAN AXIOM.

The determining factor of every philosophical dissertation is of course

some very general supposition which is taken as established and which

exercises a controlling influence over all the observations of its author.

In this case this determining supposition is found in what M. Mouret

calls his “_axiom_ of _symmetry_.” The same is thus stated by him “_Two

things which have the same symmetrical relations to a third thing have

between them that same relation._”

M. Mouret is not one of those scholars that lack hospitality for

other writings than those of their own nationality. From this fault

so noticeable in the work of so many of the French scholars M. Mouret

himself seems to be free. Indeed so far as regards the previous work done

in the domain he sets himself to examine, he accords almost exclusive

esteem to the writings of English thinkers. In fact he declares himself

so far as regards his present topic a disciple of Mr. Herbert Spencer

and puts his “axiom of symmetry” as an adaptation of that maxim of his

said master which is of the tenor as follows, viz: “_Things which have

a definite relation to the same thing have a definite relation to one

another._” This maxim, as Mr. Spencer tells us, was suggested to him by

a remark of the late eminent author who is known to the world under the

pseudonym of George Eliot, who herself stated it under the form “_Things

that have a constant relation to the same thing have a constant relation

to each other._”

Those who are well acquainted with the psychology of Mr. Spencer will

recognise that this maxim of his is made by him the very backbone of all

his observations upon reasoning. If it has the validity which he imputes

to it, it has an importance which it will be hard to overestimate, but if

on the contrary, and as we shall submit, it is in every form in which it

has been stated, certainly unsound and misleading, it is high time that

its virtue should be brought into question.

The _dicta_ of the masters whether they first enounce the same or whether

they only give currency thereto by their ratification are always proper

subjects for special scrutiny. There is always found a disposition to

accept them on their mere _ipse dixit_ without any attempt at criticism

or independent observation. This is decisively _not_ the scientific mood

or mode. The spirit of that modern leaven that is currently referred

to under the name of Science is characteristically a critical one, and

one that is considerably irreverent in regard to the authority of mere

personality. In this it is happily distinguished from the spirit that has

marked the past history of what may be called the “regular” schools of

philosophy.

M. Mouret is not alone in his inadvertent esteem for the maxim in

question. In the issue of _Mind_ for October 1891 Mr. L. T. Hobhouse

publishes an article entitled “Induction and Deduction,” in which he

gives an undue appraisal to the worth of the maxim under consideration,

even though the author of the article seems to be well aware that said

maxim stands in much need of qualification.

We venture to say that this maxim in all its forms has gained whatever

currency it has enjoyed in virtue alone of the incompetent comprehension

that too generally prevails in regard to the nature and characteristics

of that sort of things that are relations.

A notable example of this lack of comprehension is supplied in the

logical treatise of Mr. Carveth Read, a work ostensibly founded upon

the significance of the category of relation and yet in which at the

very start the author tells us that a relation is something which is

indefinable.

II. IMPORTANCE OF RELATION-LORE.

This topic of relations is one that is neglected in a degree that

reflects no credit upon the pretensions of those who undertake to

instruct others in matters logical and philosophical. The thing itself

is in the thinking of every one and the term and its derivations are

in universal use. They are used as though they imported an idea that

no one was liable to misapply or to misunderstand. The truth, however,

is that of all the stock terms in our graver discourse this very word

“relation” and its derivatives are the ones that are oftenest heard and

read without any lucidity of mind concerning their proper intent as a

part of their context. They are used with an assortment of meanings and

non-meanings that are quite distracting to try to follow and quite vain

to try and reconcile. In particular the difference between _relationship_

and _relation_, between the _ground_ or _foundation_ of the relation

and the relation itself, between the plural fact, whether of tendency,

interaction, transition, or _status_, that is a co-condition with the

relations, and the relations that co-condition that same plural fact, is

constantly ignored in thinking and in the expression thereof, to the more

or less confusion in, and inconsequence of, the whole discourse delivered.

It is no slight commendation of the perspicacity of M. Mouret to observe

that he has discovered that the way towards a resolution of the problems

he sets himself to work out lies through what to him appears the

altogether unexplored regions of relation-lore, for it is evident that he

regards himself as a pioneer in this field.

III. WORKS ON RELATION-LORE IN THE ENGLISH LANGUAGE.

In observing this we cannot but hold M. Mouret unfortunate in not having

been put upon better lines of inquiry. He seems to have been wholly

unaware of the treasures of investigation in this domain that exist in

the English language and that for many years have been available for

the student. His case in this respect is seen in the exaltation which

he gives to the semi-popular discourses of Mr. Spencer and Mr. Read, as

contrasted with the profound researches of DeMorgan and Boole and their

disciples. It is evident that he has judged concerning the comparative

quality of the various lines of English research not after an examination

of his own, but after the current popular renown. For example, he speaks

of the work of DeMorgan and Boole as presenting “only a simple mode of

representing some of the logical laws” and as being “surrounded with a

formidable and complicated apparel which disguises the value of their

tentatives.”

Since M. Mouret is manifestly an earnest student of the topic of

relation-lore this language shows that he has at best only a second or

third-hand knowledge of what DeMorgan and Boole really did. He ought

to have known that in the recondite field of research in question all

really competent treatment of the same would be very far from having

any “popular” quality. For a man to discourse of relation-lore in

ignorance of what DeMorgan, the very father of the “Logic of Relatives,”

accomplished is like discoursing of Darwinism in ignorance of “The Origin

of Species.”

We opine that when M. Mouret shall have consulted the great memoir

of DeMorgan in the tenth volume of the “Cambridge Philosophical

Transactions” or better, when he shall have become acquainted with

the more developed work of Mr. C. S. Peirce, to whom beyond question

relation-lore is most indebted for its present state of progress, he

will have a better esteem for the value of the “tentatives” of DeMorgan

and Boole and their disciples. Mr. Peirce has published three principal

papers on the subject in question. The first of these was published in

1870 in the ninth volume of the “Memoirs of the American Academy of Arts

and Sciences.” Then in 1880 and in 1884, while Mr. Peirce was lecturer

on logic at Johns Hopkins University, he published in the _American

Journal of Mathematics_ two papers dealing more or less extensively

with relation-lore. One of these his “_Hauptwerk_” as it is called by

Professor Schroeder of Carlsruhe, appears in the third volume of the

journal mentioned and the other in the seventh volume of the same.

Mr. Peirce was one of the contributors to our new American “Century

Dictionary,” and in that work under the definitions of Relation and

Relativity there appears a summary treatment of the subject which is as

we take it the work of Mr. Peirce and which might have given to M. Mouret

hints which he would have appreciated. Also the editor of this magazine

in his article “Are there Things in Themselves?” in the January 1892

number thereof incidentally touches upon the topic under consideration in

such a way as to correct some of the more inveterate misconceptions.

IV. M. MOURET’S THEORY OF RELATIONS.

The article of M. Mouret is in so many points so excellent a discourse

that the chief reflection one is inclined to make is that upon its own

principles it ought to have been better. He seems to have been widely

awake to the primordial nature of relations as philosophical data.

He says: “Every notion or relation is a _function_ of relations more

directly known and enters as a relational element into other relations

less proximate to the common sources,” and also that “every concept or

notion ought to resolve into a group of relations.”
