Good sense is the most equitably distributed thing in the world, for each man considers himself so well provided with it that even those who are most difficult to satisfy in everything else do not usually wish to have more of it than they have already. It is not likely that everyone is, mistaken in this; it shows, rather, that the ability to judge rightly and separate the true from the false, which is essentially what is called good sense or reason, is by nature equal in all men, and thus that our opinions differ not because some men are better endowed with reason than others, but only because we direct our thoughts along different paths, and do not consider the same things, for it is not enough to have a good mind: what is most important is to apply it rightly. The greatest souls are capable of the greatest vices; and those who walk very slowly can advance much further, if they always keep to the direct road, than those who run and go astray.

For my part, I have never presumed my mind to be more perfect than average in any way; I have, in fact, often wished that my thoughts were as quick, or my imagination as precise and distinct, or my memory as capacious or prompt, as those of some other men.
And I know of no other qualities than these which make for the perfection of the mind; for as to reason, or good sense, inasmuch as it alone makes us men and distinguishes us from the beasts, I am quite willing to believe that it is whole and entire in each of us, and to follow in the common opinion of the philosophers who say that there are differences of more or less only among the accidents, and not among the forms, or natures, of the individuals of a single species.
