10. Now in this, whether you agree with me or not, let me be at least sure you understand me. Σοφία, I say, is the virtue, μωρία is the vice, of all the three faculties of art, science, and literature. There is for each of them a negative and a positive side, as well as a zero. There is a nescience for zero in science--with wise science on one side, foolish science on the other: ἀτεχνία for zero in art, with wise art on one side, foolish art on the other; and ἄνοια for zero in νοῦς, with wise νοῦς on one side, foolish νοῦς on the other. 11. You will smile at that last expression, 'foolish νοῦς.' Yet it is, of all foolish things, the commonest and deadliest. We continually complain of men, much more of women, for reasoning ill. But it does not matter how they reason, if they don't conceive basely. Not one person in a hundred is capable of seriously reasoning; the difference between man and man is in the quickness and quality, the accipitrine intensity, the olfactory choice, of his νοῦς. Does he hawk at game or carrion? What you choose to grasp with your mind is the question;--not how you handle it afterwards. What does it matter how you build, if you have bad bricks to build with; or how you reason, if every idea with which you begin is foul or false? And in general all fatal false reasoning proceeds from people's having some one false notion in their hearts, with which they are resolved that their reasoning _shall_ comply. But, for better illustration, I will now take my own special subject out of the three;--τέχνη. I have said that we have, for its zero, ἀτεχνία, or artlessness--in Latin, 'inertia,' opposed to 'ars.' Well, then, we have, from that zero, wise art on the one side, foolish art on the other; and the finer the art, the more it is capable of this living increase, or deadly defect. I will take, for example, first, a very simple art, then a finer one; but both of them arts with which most of you are thoroughly acquainted.
