On the one hand this critique of knowledge applies to the empirical knowledge of Locke, which asserts itself to be grounded on experience, and, on the other hand, it also deals with what claims to be on the whole a more metaphysical kind of philosophy - the Wolffian and German - which had also taken up the line of proceeding on the more empiric method which has been depicted.

But this last has at the same time kept itself separate from the merely empiric method, inasmuch as its main efforts have been directed towards making such categories of thought as those of potentiality, actuality, God, &c., have as their foundation categories of the understanding, and then reasoning from them. The Kantian philosophy is in the first instance directed against both. Kant takes away the objective significance of the determinations of the Wolffian metaphysics, and shows how they must be ascribed to subjective thought alone. At the same time Jacobi likewise declared himself against this metaphysic, but since he started more especially from the standpoint of the French and Germans, his point of view was different: he asserts that our finite thought can set forth finite determinations alone, and thus can only consider God and Spirit in accordance with finite relationships. On the practical side there reigned at that time the so-called happiness theory, since man’s inherent Notion and the way to realize this Notion was apprehended in morality as a satisfaction of his desires. As against this Kant has very rightly shown that it involves a heteronomy and not an autonomy of reason - a determination through nature and consequently an absence of freedom. But because the rational principle of Kant was formal, and his successors could not make any further progress with reason, and yet morality had to receive a content, Fries and others must still be called Hedonists though they avoid giving themselves the name.

In the third place, as regards the relation of the categories to the material which is given through experience, there is according to Kant already inherent in the subjective determinations of thought, e.g. in those of cause and effect, the capacity of themselves to bind together the differences which are present in that material. Kant considers thought as in great measure a synthetic activity, and hence he represents the main question of Philosophy to be this, “How are synthetic judgments a priori possible?”(4) Judgment signifies the combination of thought-determinations as subject and predicate. Synthetic judgments a priori are nothing else than a connection of opposites through themselves, or the absolute Notion, i.e. the relations of different determinations such as those of cause and effect, given not through experience but through thought. Space and time likewise form the connecting element; they are thus a priori, i.e. in self-consciousness. Since Kant shows that thought has synthetic judgments a priori which are not derived from perception, he shows that thought is so to speak concrete in itself. The idea which is present here is a great one, but, on the other hand, quite an ordinary signification is given it, for it is worked out from points of view which are inherently rude and empirical, and a scientific form is the last thing that can be claimed for it. In the presentation of it there is a lack of philosophical abstraction, and it is expressed in the most commonplace way; to say nothing more of the barbarous terminology, Kant remains restricted and confined by his psychological point of view and empirical methods.

To mention one example only of big barbarous expressions, Kant calls his philosophy (Kritik der reinen Vernunft, p. 19) a Transcendental philosophy, i.e. a system of principles of pure reason which demonstrate the universal and necessary elements in the self-conscious understanding, without occupying themselves with objects or inquiring what universality and necessity are; this last would be transcendent. Transcendent and transcendental have accordingly to be clearly distinguished. Transcendent mathematics signifies the mathematics in which the determination of infinitude is made use of in a preeminent degree: in this sphere of mathematics we say, for instance, that the circle consists of an infinitude of straight lines; the periphery is represented as straight, and since the curve is represented as straight this passes beyond the geometric category and is consequently transcendent. Kant, on the contrary, defines the transcendental philosophy as not a philosophy which by means of categories passes beyond its own sphere, but one which points out in subjective thought, in consciousness, the sources of what may become transcendent. Thought would thus be transcendent if the categories of universality, of cause and effect, were predicated of the object, for in this way men would from the subjective element ‘transcend’ into another sphere. We are not justified in so doing as regards the result nor even to begin with, since we merely contemplate thought within thought itself. Thus we do not desire to consider the categories in their objective sense, but in so far as thought is the source of such synthetic relationships; the necessary and universal thus here receive the significance of resting in our faculties of knowledge.
