Excerpt from A Brief History of Modern Philosophy The subject matter of the history of philosophy consists of the efforts which individual thinkers have made to explain or perchance to solve the ultimate problems Of knowledge and of being. Modern philosophy - i. E. The philosophy of the last three centuries - has been specially concerned with four great problems. These problems, moreover - as I have Shown in my Philosophic Problems (eng. Tr. 190 5)-are intimately related to each other, and there likewise exists a most significant analogy between them, in that the antithesis of continuity and discontinuity is of fundamental importance in each of them, except that it manifests itself under different forms.
