"Why, those are petty passions, by which, on the contrary, man must not let himself be enthralled. Man must make sacrifices for a great idea, a great cause!" A "great idea," a "good cause," is, it may be, the honor of God, for which innumerable people have met death; Christianity, which has found its willing martyrs; the Holy Catholic Church, which has greedily demanded sacrifices of heretics; liberty and equality, which were waited on by bloody guillotines. He who lives for a great idea, a good cause, a doctrine, a system, a lofty calling, may not let any worldly lusts, any self-seeking interest, spring up in him. Here we have the concept of _clericalism_, or, as it may also be called in its pedagogic activity, school-masterliness; for the idealists play the schoolmaster over us. The clergyman is especially called to live to the idea and to work for the idea, the truly good cause. Therefore the people feel how little it befits him to show worldly haughtiness, to desire good living, to join in such pleasures as dancing and gaming,--in short, to have any other than a "sacred interest." Hence too, doubtless, is derived the scanty salary of teachers, who are to feel themselves repaid by the sacredness of their calling alone, and to "renounce" other enjoyments. Even a directory of the sacred ideas, one or more of which man is to look upon as his calling, is not lacking. Family, fatherland, science, etc., may find in man a servant faithful to his calling. Here we come upon the old, old craze of the world which has not yet learned to do without clericalism,--that to live and work _for an idea_ is man's calling, and according to the faithfulness of its fulfilment his _human_ worth is measured. This is the dominion of the idea; in other words, it is clericalism. _E. g._, Robespierre, St. Just, etc., were priests through and through, inspired by the idea, enthusiasts, consistent instruments of this idea, idealistic men. So St. Just exclaims in a speech, "There is something terrible in the sacred love of country; it is so exclusive that it sacrifices everything to the public interest without mercy, without fear, without human consideration. It hurls Manlius down the precipice; it sacrifices its private inclinations; it leads Regulus to Carthage, throws a Roman into the chasm, and sets Marat, as a victim of his devotion, in the Pantheon." Now, over against these representatives of ideal or sacred interests stands a world of innumerable "personal" profane interests. No idea, no system, no sacred cause is so great as never to be outrivaled and modified by these personal interests. Even if they are silent momentarily, and in times of rage and fanaticism, yet they soon come uppermost again through "the sound sense of the people." Those ideas do not completely conquer till they are no longer hostile to personal interests, _i. e._ till they satisfy egoism.
