Spiritual men have _taken into their head_ something that is to be realized. They have _concepts_ of love, goodness, and the like, which they would like to see _realized_; therefore they want to set up a kingdom of love on earth, in which no one any longer acts from selfishness, but each one "from love." Love is to _rule_. What they have taken into their head, what shall we call it but--_fixed idea_? Why, "their head is _haunted_." The most oppressive spook is _Man_. Think of the proverb, "The road to ruin is paved with good intentions." The intention to realize humanity altogether in oneself, to become altogether man, is of such ruinous kind; here belong the intentions to become good, noble, loving, etc. In the sixth part of the "_Denkwuerdigkeiten_" p. 7, Bruno Bauer says: "That middle class, which was to receive such a terrible importance for modern history is capable of no self-sacrificing action, no enthusiasm for an idea, no exaltation; it devotes itself to nothing but the interests of its mediocrity; _i. e._ it remains always limited to itself, and conquers at last only through its bulk, with which it has succeeded in tiring out the efforts of passion, enthusiasm, consistency,--through its surface, into which it absorbs a part of the new ideas." And (p. 6) "It has turned the revolutionary ideas, for which not it, but unselfish or impassioned men sacrificed themselves, solely to its own profit, has turned spirit into money.--That is, to be sure, after it had taken away from those ideas their point, their consistency, their destructive seriousness, fanatical against all egoism." These people, then, are not self-sacrificing, not enthusiastic, not idealistic, not consistent, not zealots; they are egoists in the usual sense, selfish people, looking out for their advantage, sober, calculating, etc. Who, then, is "self-sacrificing"?[49] In the full sense, surely, he who ventures everything else for _one thing_, one object, one will, one passion, etc. Is not the lover self-sacrificing who forsakes father and mother, endures all dangers and privations, to reach his goal? Or the ambitious man, who offers up all his desires, wishes, and satisfactions to the single passion, or the avaricious man who denies himself everything to gather treasures, or the pleasure-seeker, etc.? He is ruled by a passion to which he brings the rest as sacrifices. And are these self-sacrificing people perchance not selfish, not egoists? As they have only one ruling passion, so they provide for only one satisfaction, but for this the more strenuously; they are wholly absorbed in it. Their entire activity is egoistic, but it is a one-sided, unopened, narrow egoism; it is possessedness.
