In sum, then, we may say that "philosophy" has come to be understood at least in modern times as a general term covering the various disciplines just enumerated.
The position assigned to logic by Kant is not, in all probability, one which can be defended; indeed, it is hard to see how Kant himself, in consistency with the critical doctrine of knowledge, could have retained many of the older logical theorems, but the precision with which the position was stated, and the sharpness with which logic was marked off from cognate philosophic disciplines, prepared the way for the more thoughtful treatment of the whole question.
It is not till we come to Aristotle - the encyclopaedist of the ancient world - that we find a demarcation of the different philosophic disciplines corresponding, in the main, to that still current.
"Philosophy," as a term of general application, was not, indeed restricted by Aristotle or his successors to the disciplines just enumerated.
The order in which, for clearness of exposition, it will be most convenient to consider these disciplines will be psychology, epistemology or theory of knowledge, and metaphysics, then logic, aesthetics and ethics.
