'Pure experience' is the name I gave to the immediate flux of life which furnishes the material to our later reflection with its conceptual categories.

True to her inveterate habit, rationalism reverts to 'principles,' and thinks that when an abstraction once is named, we own an oracular solution.

The absolute things, the last things, the overlapping things, are the truly philosophic concerns; all superior minds feel seriously about them, and the mind with the shortest views is simply the mind of the more shallow man.

It is only by risking our persons from one hour to another that we live at all. And often enough our faith beforehand in an uncertified result is the only thing that makes the result come true.

The self-same atoms which, chaotically dispersed, made the nebula, now, jammed and temporarily caught in peculiar positions, form our brains; and the 'evolution' of brains, if understood, would be simply the account of how the atoms came to be so caught and jammed.

Ideas are so much flat psychological surface unless some mirrored matter gives them cognitive lustre. This is why as a pragmatistI have so carefully posited 'reality' ab initio, and why throughout my whole discussion, I remain an epistemologist realist.

Habit is a second nature, or rather, it is 'ten times nature'.
