- Concepts by intuition and by postulation
A concept by intuition is one which denotes, and the complete meaning of which is given by, something which is immediately apprehended. Northrop gives blue in "the sense of the sensed color" as an example of a concept by intuition. [...]
The other kind is concepts by postulation. A concept by postulation is one the meaning of which in whole or in part is designated by the postulates of the deductive theory in which it occurs. Blue in the sense of the frequency or wavelength in electromagnetic theory is a concept by postulation.
