Such facts as these prove that this department of philosophy is not superfluous. The question next arises whether this part alone is sufficient to make men wise. The problem shall be treated at the proper time; but at present, omitting all arguments, is it not clear that we need someone whom we may call upon as our preceptor in opposition to the precepts of men in general?
