Since the doctrine was propounded in an intellectual environment where such statements were not commonplaces, where in fact a logic was reigning which challenged these convictions at every point, it is not surprising that it was put forth with a controversial coloring, being directed particularly at the dominant idealistic logic. The point of contact and hence the point of conflict between the logic set forth and the idealistic logic are not far to seek. The logic based on idealism had, as a matter of fact, treated knowledge from the standpoint of an account of thought--of thought in the sense of conception, judgment, and inferential reasoning. But while it had inherited this view from the older rationalism, it had also learned from Hume, via Kant, that direct sense or perceptual material must be taken into account. Hence it had, in effect, formulated the problem of logic as the problem of the connection of logical thought with sense-material, and had attempted to set forth a metaphysics of reality based upon various ascending stages of the completeness of the rationalization or idealization of given, brute, fragmentary sense material by synthetic activity of thought. While considerations of a much less formal kind were chiefly influential in bringing idealism to its modern vogue, such as the conciliation of a scientific with a religious and moral point of view and the need of rationalizing social and historic institutions so as to explain their cultural effect, yet this logic constituted the _technique_ of idealism--its strictly intellectual claim for acceptance.
