7. What then? can a man make this resolve, and so stand up faultless? He cannot; but this much he can—to be ever straining towards faultlessness. For happy it were if, by never relaxing this industrious heed, we shall rid ourselves of at least a few of our faults. But now, when thou sayest, _From to-morrow I shall be heedful_, know that this is what thou art saying:—_To-day I shall be shameless, importunate, abject; it shall be in others’ power to afflict me; to-day I shall be wrathful, envious_. Lo, to how many vices dost thou give place! But if aught be well to-morrow, how much better to-day? if to-morrow suit, how much better to-day? Yea, and for this, too, that thou mayest have the power to-morrow, and not again put it off till the third day. CHAPTER III. ON DISPUTATION. 1. What things a man must have learned in order to be able to reason well have been accurately defined by our philosophers; but in the fitting use of them we are wholly unexercised. Give any one of us whom ye please some ignorant man for a disputant, and he shall find no way to deal with him; but if, when he hath moved him a little, the man answer beside the purpose, he is no longer able to manage him, but either he will revile him, or mock him, and say, _He is an ignorant fellow; nothing can be done with him_. 2. But a guide, when he hath found one straying from the way, leads him into the proper road, and does not mock him or revile him, and then go away. And do thou show such a man the truth, and thou shalt see that he will follow it. But so long as thou dost not show it, mock him not, but be sensible rather of thine own incapacity.
