   • 1902, William James, The Varieties of Religious Experience, Lecture 3:

     The opinion opposed to mysticism in philosophy is sometimes spoken of as rationalism. Rationalism insists that all our beliefs ought ultimately to find for themselves articulate grounds. Such grounds, for rationalism, must consist of four things: (1) definitely statable abstract principles; (2) definite facts of sensation; (3) definite hypotheses based on such facts; and (4) definite inferences logically drawn.

4. Elaboration of theories by use of reason alone without appeal to experience, such as in mathematical systems.
