He appears just as uninspired in comparison with Hegel in his treatment of the antithesis of good and evil. "One thinks he is saying something great," Hegel remarks "if one says that mankind is by nature good, but it is forgotten that one says something far greater in the words 'man is by nature evil.'" According to Hegel, evil is the form in which the mechanical power of evolution shows itself, and indeed in this lies the double idea that each new step forward appears as an outrage against a sacred thing, as rebellion against the old, dying, but through custom, sanctified, circumstances, and on the other hand that since the rising of class antagonism, the evil passions of men, greed and imperiousness serve as the levers of historical progress, of which, for example, the history of feudalism and the bourgeoisie affords a conspicuous proof. But Feuerbach does not trouble himself to examine the role of moral evil. History is to him a particularly barren and unwonted field. Even his statement, "Man as he sprang from nature originally was only a mere creature, not a man." "Man is a product of human society, of education, and of history." Even this statement remains from his standpoint absolutely unproductive. What Feuerbach communicates to us respecting morals must therefore be exceedingly narrow. The desire for happiness is born within man and must hence be the foundation of all morality. But the desire for happiness is limited in two ways; first, through the natural results of our acts; after the dissipation comes the headache, as a result of habitual excess, sickness; in the second place, through its results upon society, if we do not respect the similar desire for happiness on the part of other people, they resist us and spoil our pursuit of happiness. It follows, therefore, that in order to enjoy our pursuit of happiness, the result of our acts must be rightly appreciated, and, on the other hand, must allow of the carrying out of the same acts on the part of others. Practical self-control with regard to ourselves and love, always love, in our intercourse with others are therefore the foundation rules of Feuerbach's morality, from which all others lead, and neither the enthusiastic periods of Feuerbach nor the loud praises of Starcke can set off the thinness and flatness of this pair of utterances.
