Johann Friedrich Herbart (; 4 May 1776 – 14 August 1841) was a German philosopher, psychologist and founder of pedagogy as an academic discipline.

Herbart is now remembered amongst the post-Kantian philosophers mostly as making the greatest contrast to Hegel—in particular in relation to aesthetics. His educational philosophy is known as Herbartianism.

Life

Herbart was born on 4 May 1776 in Oldenburg. Growing up as a fragile child because of an unfortunate accident, Herbart was taught by his mother at home until the age of 12. He continued his schooling at the Gymnasium for six years, and showed interest in philosophy, logic and Kant's work involving the nature of knowledge obtained from experience with reality. His education then continued at Jena, whereupon he studied philosophy and came to disagree with his teacher Fichte precisely because Fichte had taught him to think in a logical manner. He composed a few essays, which he had given to Fichte during his years at Jena, criticising the works of Schelling.

Leaving Jena after three years, he tutored the children of Herr von Steiger, who was the Governor of Interlaken. During these three years, his tutoring job sparked his interest in educational reform. While tutoring in Switzerland, Herbart met and came to know Pestalozzi, the Swiss educator involved with issues of reform in the schools. Resigning from his tutoring position, Herbart went on to study Greek and mathematics at Bremen for three years, and then eventually moved on to attend Göttingen from 1801 to 1809. While there, he received a privat-docent for his endeavours in educational studies after receiving his doctoral degree. He gave his first philosophical lectures at Göttingen around 1805, whence he removed in 1809 to occupy the chair formerly held by Kant at Königsberg. Here he also established and conducted a seminary of pedagogy till 1833, when he returned once more to Göttingen, and remained there as professor of philosophy till his death. Herbart gave his last lecture in perfectly good health and then unexpectedly died two days later from apoplexy. He is buried in Albanifriedhof Cemetery in Göttingen.

Herbart was very much focused on his studies, and "he barely saw the world outside his study and the classrooms" making "his world the world of books and only books". Regardless of his relentless studying, he met an eighteen-year-old English girl named Mary Drake one night when playing a game of charades. He became acquainted with her and asked her for her hand in marriage. They lived a happy life with Mary supporting all of her husband's pursuits and contributions to the fields of pedagogy and psychology.

Philosophy

Philosophy, according to Herbart, begins with reflection upon our empirical conceptions, and consists in the reformation and elaboration of these, its three primary divisions being determined by as many distinct forms of elaboration. Logic, which stands first, has to render our conceptions and the judgments and reasonings arising from them clear and distinct. But some conceptions are such that the more distinct they are made the more contradictory their elements become; so to change and supplement these as to make them at length thinkable is the problem of the second part of philosophy, or metaphysics. There is still a class of conceptions requiring more than a logical treatment, but differing from the last in not involving latent contradictions, and in being independent of the reality of their objects, the conceptions that embody our judgments of approval and disapproval; the philosophic treatment of these conceptions falls under aesthetics.

Logic

In Herbart's writings logic receives comparatively meagre notice; he insisted strongly on its purely formal character and expressed himself in the main at one with Kantians such as Fries and Krug.

Metaphysics

As a metaphysician, he starts from what he terms the higher scepticism of the Humean–Kantian sphere of thought, the beginnings of which he discerns in Locke's perplexity about the idea of substance. The validity of even the forms of experience is called in question on account of the contradictions they are found to involve. And yet that these forms are given to us, as truly as sensations are, follows beyond doubt when we consider that we are as little able to control the one as the other. To attempt at this stage a psychological inquiry into the origin of these conceptions would be doubly a mistake; for we should have to use these illegitimate conceptions in the course of it, and the task of clearing up their contradictions would still remain, whether we succeeded in our enquiry or not.

But how are we to set about this task? We have given to us a conception A uniting among its constituent marks two that prove to be contradictory, say M and N; and we can neither deny the unity nor reject one of the contradictory members. For to do either is forbidden by experience; and yet to do nothing is forbidden by logic. We are thus driven to the assumption that the conception is contradictory because incomplete; but how are we to supplement it? What we have must point the way to what we want, or our procedure will be arbitrary. Experience asserts that M is the same (i.e. a mark of the same concept) as N, while logic denies it; and so it being impossible for one and the same M to sustain these contradictory positions there is but one way open to us; we must posit several Ms. But even now we cannot say one of these Ms is the same as N, another is not; for every M must be both thinkable and valid. We may, however, take the Ms not singly but together; and again, no other course being open to us, this is what we must do; we must assume that N results from a combination of Ms. This is Herbart's method of relations, the counterpart in his system of the Hegelian dialectic.

In ontology, this method is employed to determine what in reality corresponds to the empirical conceptions of substance and cause, or rather of inherence and change. But first we must analyse this notion of reality itself, to which our scepticism had already led us, for, though we could doubt whether the given is what it appears, we cannot doubt that it is something; the conception of the real thus consists of the two conceptions of being and quality. That which we are compelled to posit, which cannot be sublated, is that which is, and in the recognition of this lies the simple conception of being. But when is a thing thus posited? When it is posited as we usually posit the things we see and taste and handle. If we were without sensations, i.e. were never bound against our will to endure the persistence of a presentation, we should never know what being is.

Keeping fast hold of this idea of absolute position, Herbart leads us next to the quality of the real: This must exclude everything negative; for non-A sublates instead of positing, and is not absolute, but relative to A. The real must be absolutely simple; for if it contain two determinations, A and B, then either these are reducible to one, which is the true quality, or they are not, when each is conditioned by the other and their position is no longer absolute. All quantitative conceptions are excluded, for quantity implies parts, and these are incompatible with simplicity. But there may be a plurality of reals, albeit the mere conception of being can tell us nothing as to this.

The doctrine here developed is the first cardinal point of Herbart's system, and the name pluralistic realism has been proposed for it by Otto Pfleiderer.Otto Pfleiderer, The Philosophy of Religion on the Basis of Its History, Volume 2, Williams and Norgate, 1887, pp. 116, 215, 298.

The contradictions he finds in the common-sense conception of inherence, or of a thing with several attributes, will now become obvious. Take some thing, say A, having n attributes, a, b, c ...: we are forced to posit each of these because each is presented in intuition. But in conceiving A we make, not n positions, still less n+1 positions, but one position simply; for common sense removes the absolute position from its original source, sensation. So when we ask, What is the one posited? we are told the possessor of a, b, c or in other words, their seat or substance. But if so, then A, as a real, being simple, must be equal to a; similarly it must be b; and so on.

Now this would be possible if a, b, c ... were only contingent aspects of A, as for example 23, , 4+3+1 are contingent aspects of 8. Such, of course, is not the case, and so we have as many contradictions as there are attributes; for we must say A is a, is not a, is b, is not b, etc. There must then, according to the method of relations, be several As. For a let us assume A1+A1+A1 ... ; for b, A2+A2+A2 ...; and so on for the rest. But now what relation can there be among these several As, which will restore to us the unity of our original A or substance? There is just one; we must assume that the first A of every series is identical, just as the centre is the same point in every radius.

By way of concrete illustration Herbart instances "the common observation that the properties of things exist only under external conditions. Bodies, we say, are coloured, but color is nothing without light, and nothing without eyes. They sound, but only in a vibrating medium, and for healthy ears. Colour and tone present the appearance of inherence, but on looking closer we find they are not really immanent in things but rather presuppose a communion among several." The result then is briefly thus: In place of the one absolute position, which in some unthinkable way the common understanding substitutes for the absolute positions of the n attributes, we have really a series of two or more positions for each attribute, every series, however, beginning with the same (as it were, central) real (hence the unity of substance in a group of attributes), but each being continued by different reals (hence the plurality and difference of attributes in unity of substance). Where there is the appearance of inherence, therefore, there is always a plurality of reals; no such correlative to substance as attribute or accident can be admitted at all. Substantiality is impossible without causality, and to this as its true correlative we now turn.

The common-sense conception of change involves at bottom the same contradiction of opposing qualities in one real. The same A that was a, b, c ... becomes a, b, d ...; and this, which experience thrusts upon us, proves on reflection unthinkable. The metaphysical supplementing is also fundamentally as before. Since c depended on a series of reals A3+A3+A3 ... in connection with A, and d may be said similarly to depend on a series A4+A4+A4 ..., then the change from c to d means, not that the central real A or any real has changed, but that A is now in connection with A4, etc., and no longer in connection with A3, etc.

But to think a number of reals in connection (Zusammensein) will not suffice as an explanation of phenomena; something or other must happen when they are in connection; what is it? The answer to this question is the second hinge-point of Herbart's theoretical philosophy.
