We ought… to think of the art of discourse just as we think of the other arts, and not to form opposite judgments about similar things, nor show ourselves intolerant toward that power which, of all the faculties which belong to the nature of man, is the source of most of our blessings. For in the other powers which we possess, … we are in no respect superior to other living creatures; nay, we are inferior to many in swiftness and in strength and in other resources; but, because there has been implanted in us the power to persuade each other and to make clear to each other whatever we desire, not only have we escaped the life of wild beasts, but we have come together and founded cities and made laws and invented arts; and generally speaking, there is no institution devised by man which the power of speech has not helped us to establish. For this it is which has laid down laws concerning things just and unjust, and things honorable and base; and if it were not for these ordinances we should not be able to live with one another. It is by this also that we confute the bad and extol the good. Through this we educate the ignorant and appraise the wise; for the power to speak well is taken as the surest index of a sound understanding, and discourse which is true and lawful and just is the outward image of a good and faithful soul.
