The construction of philosophical family trees for Nietzsche has ever been one of the favorite pastimes of his critics and interpreters. Thus Dr. Oscar Levy, editor of the English translation of his works, makes him the heir of Goethe and Stendhal, and the culminating figure of the "Second Renaissance" launched by the latter, who was "the first man to cry halt to the Kantian philosophy which had flooded all Europe."[1] Dr. M. A. Mügge agrees with this genealogy so far as it goes, but points out that Nietzsche was also the intellectual descendant of certain pre-Socratic Greeks, particularly Heracleitus, and of Spinoza and Stirner.[2] Alfred Fouillée, the Frenchman, is another who gives him Greek blood, but in seeking his later forebears Fouillée passes over the four named by Levy and Mügge and puts Hobbes, Schopenhauer, Darwin, Rousseau and Diderot in place of them.[3] Again, Thomas Common says that "perhaps Nietzsche is most indebted to Chamfort and Schopenhauer," but also allows a considerable influence to Hobbes, and endeavors to show how Nietzsche carried on, consciously and unconsciously, certain ideas originating with Darwin and developed by Huxley, Spencer and the other evolutionists.[4] Dr. Alexander Tille has written a whole volume upon this latter relationship.[5] Finally, Paul Elmer More, the American, taking the cue from Fouillée, finds the germs of many of Nietzsche's doctrines in Hobbes, and then proceeds to a somewhat elaborate discussion of the mutations of ethical theory during the past two centuries, showing how Hume superimposed the idea of sympathy as a motive upon Hobbes' idea of self-interest, and how this sympathy theory prevailed over that of self-interest, and degenerated into sentimentalism, and so opened the way for Socialism and other such delusions, and how Nietzsche instituted a sort of Hobbesian revival.[6] Many more speculations of that sort, some of them very ingenious and some merely ingenuous, might be rehearsed. By one critic or another Nietzsche has been accused of more or less frank borrowings from Xenophanes, Democritus, Pythagoras, Callicles, Parmenides, Arcelaus, Empedocles, Pyrrho, Hegesippus, the Eleatic Zeno, Machiavelli, Comte, Montaigne, Mandeville, La Bruyère, Fontenelle, Voltaire, Kant, La Rochefoucauld, Helvétius, Adam Smith, Malthus, Butler, Blake, Proudhon, Paul Rée, Flaubert, Taine, Gobineau, Renan, and even from Karl Marx!--a long catalogue of meaningless names, an exhaustive roster of pathfinders and protestants. A Frenchman, Jules de Gaultier, has devoted a whole book to the fascinating subject.[7]
