As I am to prove morality to you, I accept the burden of proof; but you are not on that account totally without responsibility in the matter. As you must not stop your ears, or close your bodily eyes, so you must not shut the eye of the mind, or harden your heart. Were you to adopt such an attitude I should be compelled to set argument aside, and resort to such practical measures as might shock or entice you into reasonableness. Or, I might abandon you as incorrigible. It is {42} clear that I can as little show reasons to a man who will not think them with me, as I can show the road to one who will not look where I point it out. A very large amount of moral exhortation consists in the attempt to overcome apathy and inattention. Such exhortation cannot in the nature of the case be logical, because the subject's logical organ is not as yet functioning. I doubt if there is any discussion of moral matters in common life in which this form of appeal is not present in a measure sufficient to obscure the merits of the question at issue. I desire for present purposes to eliminate as far as possible all conflict and prejudices, and thus to dispense with zeal and eloquence. I shall assume, therefore, that you propose to be reasonable concerning this moral affair. By this I mean simply that you shall directly observe the facts of life, report candidly on these facts, and fully accept the implications of any judgment to which you may commit yourself. I may phrase your pledge of reasonableness thus: "Show what is right, and that it is right, and I will accept it. I mean my action to be good, and ask only to have the good demonstrated to me, that I may intelligently adopt it." {43} II It is commonly believed that whereas the logic of _prudence_ is unimpeachable, there is a hiatus between this level of morality and those above. To drink one's self to death is a species of folly that the poorest intelligence can understand; but the folly in meanness, injustice, or impiety is a harder matter. Believing as I do that the folly is equally demonstrable in all of these cases, I propose not to accept your ready assent in the simpler case until its grounds have been made as clear and definite as possible. I feel convinced that prudence is not so simple a matter as appears; in fact that it involves the whole ethical dialectic.
