If ‘common sense’ in this philosophy means only unintelligent opinion, as opposed to the judgments of thinkers, Reid’s response to the sceptic may well be regarded as an arrest of intelligence,—blind dogmatism instead of philosophy. But candid critics interpret words in the meaning intended by those who use them. This appeal to the judgments named those of the common sense, is intended as an appeal to reason itself—reason, that is to say, in its final form in a finite intelligence, whose experience of the universe is incomplete, and working under conditions imposed upon its exercise in intelligent beings who are not omniscient. Reid’s Common Sense is the final perception of a being who can know the universe of reality only in part, and is therefore needed by man in that intermediate position in which an absolute beginning or end of things must be to him incomprehensible. It is an appeal to that which must in reason be final, in an intelligence that only partly shares in divine omniscient reason. Although its judgments are not evolved from premises, they are nevertheless what all men, except infants and lunatics, more or less distinctly acknowledge in their individual actions, although they may misconstrue them in their uneducated opinions, or spoil them by indulgence in purely speculative systems. The divine inspiration of the common sense is therefore man’s final support, amidst the so-called ‘contingencies’ of temporal change in himself and his surroundings. A philosophical appeal to it is of practical importance in reference to what, at the human point of view, are contingent truths of moral reasoning: the necessary truths of abstract thought, it has been well said, ‘sufficiently guard themselves.’
