_Commerce and Nobility._—Buying and selling is now regarded as something ordinary, like the art of reading and writing; everyone is now trained to it even when he is not a tradesman, exercising himself daily in the art; precisely as formerly in the period of uncivilised humanity, everyone was a hunter and exercised himself day by day in the art of hunting. Hunting was then something common: but just as this finally became a privilege of the powerful and noble, and thereby lost the character of the commonplace and the ordinary—by ceasing to be necessary and by becoming an affair of fancy and luxury:—so it might become the same some day with buying and selling. Conditions of society are imaginable in which there will be no selling and buying, and in which the necessity for this art will become quite lost; perhaps it may then happen that individuals who are less subjected to the law of the prevailing condition of things will indulge in buying and selling as a _luxury of sentiment_. It is then only that commerce would acquire nobility, and the noble would then perhaps occupy themselves just as readily with commerce as they have done hitherto with war and politics: while on the other hand the valuation of politics might then have entirely altered. Already even politics ceases to be the business of a gentleman; and it is possible that one day it may be found to be so vulgar as to be brought, like all party literature and daily literature, under the rubric: "Prostitution of the intellect." 32. _Undesirable Disciples._—What shall I do with these two youths! called out a philosopher dejectedly, who "corrupted" youths, as Socrates had once corrupted them,—they are unwelcome disciples to me. One of them cannot say "Nay," and the other says "Half and half" to everything. Provided they grasped my doctrine, the former would _suffer_ too much, for my mode of thinking requires a martial soul, willingness to cause pain, delight in denying, and a hard skin,—he would succumb by open wounds and internal injuries. And the other will choose the mediocre in everything he represents, and thus make a mediocrity of the whole,—I should like my enemy to have such a disciple. 33. _Outside the Lecture-room._—"In order to prove that man after all belongs to the good-natured animals, I would remind you how credulous he has been for so long a time. It is now only, quite late, and after an immense self-conquest, that he has become a _distrustful_ animal,—yes! man is now more wicked than ever."—I do not understand this; why should man now be more distrustful and more wicked?—"Because he now has science,—because he needs to have it!"— 34.
