In view of the derivation of the forms of thought from the forms of judgment Kant does not stop to give a detailed proof that the categories are concepts, and that they are pure.

" CATEGORIES are either classes under which all our Notions of things may be grouped, or classes under which all our Thoughts of things may be grouped; the former called Logical, we owe to Aristotle, and the latter called Metaphysical, we owe to Kant.

A single example may be given of this conciliatory tendency: space, time, and the categories are not only subjective forms of knowledge, but at the same time objective forms of reality.

The categories and the principles of the understanding were constitutive principles, the Ideas are regulative merely; their function is to guide the understanding, to give it a direction helpful for the connection of knowledge, not to inform it concerning the actual character of things.

These different categories of characters are, as it were, different peculiarities of style in the author, different modes of treating the same material, new combinations of evidence bearing on the same general principles.

The categories remain forever mere functions of thought by which no object can be given to me, but by which I can only think whatever may be given to me in intuition" (Critique of Pure Reason, Max Müller's translation, vol.

Mr. Haldane, for example, in his wonderfully clever Gifford lectures, praises Hegel to the skies, but what he tells of him amounts to little more than this, that 'the categories in which the mind arranges its experiences, and gives meaning to them, the universals in which the particulars are grasped in the individual, are a logical chain, in which the first presupposes the last, and the last is its presupposition and its truth.'
