But general considerations like these are always the weakest in their influence on mankind. Most people will find it enough to shrug their shoulders and say, "As if anything great and pure has ever been able to maintain itself on this earth without some concession to human vulgarity! Would you rather the state persecuted philosophers than paid them for official services?" Without answering this last question, I will merely say that these "concessions" of philosophy to the state go rather far at present. In the first place, the state chooses its own philosophical servants, as many as its institutions require; it therefore pretends to be able to distinguish the good and the bad philosophers, and even assumes there must be a sufficient supply of good ones to fill all the chairs. The state is the authority not only for their goodness but their numbers. Secondly, it confines those it has chosen to a definite place and a definite activity among particular men; they must instruct every undergraduate who wants instruction, daily, at stated hours. The question is whether a philosopher can bind himself, with a good conscience, to have something to teach every day, to any one who wishes to listen. Must he not appear to know more than he does, and speak, before an unknown audience, of things that he could mention without risk only to his most intimate friends? And above all, does he not surrender the precious freedom of following his genius when and wherever it call him, by the mere fact of being bound to think at stated times on a fixed subject? And before young men, too! Is not such thinking in its nature emasculate? And suppose he felt some day that he had no ideas just then--and yet must be in his place and appear to be thinking! What then?
