About Wilhelm Dilthey:
Wilhelm Dilthey was a German historian, psychologist, sociologist, and hermeneutic philosopher, who held Hegel's Chair in Philosophy at the University of Berlin. As a polymathic philosopher, working in a modern research university, Dilthey's research interests revolved around questions of scientific methodology, historical evidence and history's status as a science. He could be considered an empiricist, in contrast to the idealism prevalent in Germany at the time, but his account of what constitutes the empirical and experiential differs from British empiricism and positivism in its central epistemological and ontological assumptions, which are drawn from German literary and philosophical traditions.
All science is experiential; but all experience must be related back to and derives its its validity from the conditions and context of consciousness in which it arises, i.e., the totality of our nature.Wilhelm Dilthey
If we conceive all the changes in the physical world as reducible to the motion of atoms, motions generated by means of the fixed nuclear forces of those atoms, the whole of the world could thus be known by means of the natural sciences.Wilhelm Dilthey
