Out of all which we may define, that is to say determine, what that is, which is meant by this word “reason,” when we reckon it amongst the faculties of the mind. For “reason,” in this sense, is nothing but “reckoning,” that is adding and subtracting, of the consequences of general names agreed upon for the “marking” and “signifying” of our thoughts; I say “marking” them when we reckon by ourselves, and “signifying,” when we demonstrate or approve our reckonings to other men.
