Specific cognitions are designated by those sense organs and objects. How? “He smells with the nose,” “he sees with the eye,” “he tastes with the tongue”; and “olfactory cognition,” “visual cognition,” “gustatory cognition,” “cognition of smell,” “cognition of color,” and “cognition of taste.” And cognition becomes fivefold according to the distinction of the sense organs and objects. Therefore, contact between the sense organ and the object has preeminence. //28
