Excerpt from A History of Philosophy, From Thales to the Present Time, Vol. 1 Kant (critique of Pure Reason, Doctrine of Method, chap. 3) divides knowledge in general, as to its form, into historical (cognitio ex dati's), and rational (cognz'tz'o ea; and the latter again into mathematical (rational cognition through the construction of concepts), and philosophical (rational cognition through concepts as such). Philosophy, in its scho lastic signification, is defined by him as the system of all the branches of philosophical knowledge, but in its cosmical signification, as the science of the relation of all knowledge to the essential ends of human reason (teleologia rationis kamunae).
