Quote from ‘Syllabus: Syllabus of a course of Lectures at the Lowell Institute beginning 1903, Nov. 23. On Some Topics of Logic’
Idioscopy has two wings: (α) the Physical Sciences; and (β) the Psychical, or Human Sciences.
Psychical science borrows principles continually from the physical sciences; the latter very little from the former.
