In a striking passage, Bruno explains that evil is relative. “Nothing is absolutely bad,” he says; “because the viper is not deadly and poisonous to the viper, nor the lion to the lion, nor dragon to dragon, nor bear to bear; but each thing is bad in respect to some other, just as you, virtuous gods, are evil towards the vicious.” Again he says, “Nobody is to-day the same as yesterday.” The immanence of the universal soul in the animal world he illustrated thus: “With what understanding the ant gnaws her grain of wheat, lest it should sprout in her underground habitation! The fool says this is instinct, but we say it is a species of understanding.” These are some of Bruno’s characteristic opinions. Their influence upon subsequent philosophers has been much discussed. His conception of the universe as an “animal” corresponds with Kepler’s well-known view. Spinoza, the great pantheist of the following century, took from him the idea of an immanent God, and the distinction between _natura naturans_ and _natura naturata_. Schelling, who acknowledged Bruno as his master, found in him the principle of the indifference of contraries; Hegel, that of the absolute identity of subject and object, of the real and the ideal, of thought and things. La Croze discovers in Bruno the germs of most of Leibnitz’s theories, beginning with the monad. Symonds declares that “he anticipated Descartes’s position of the identity of mind and being. The modern theory of evolution was enunciated by him in pretty plain terms. He had grasped the physical law of the conservation of energy. He solved the problem of evil by defining it to be a relative condition of imperfect energy.... We have indeed reason to marvel how many of Bruno’s intuitions have formed the stuff of later, more elaborated systems, and still remain the best which these contain. We have reason to wonder how many of his divinations have worked themselves into the common fund of modern beliefs, and have become philosophical truisms.”[32] Hallam, who strangely undervalued Bruno, states that he understood the principle of compound forces. After making due allowance for the common tendency to read back into men’s opinions interpretations they never dreamed of, we shall find that much solid substance still remains to Bruno’s credit. He is, above all, suggestive. [32] From J. A. Symonds’s _Renaissance in Italy: The Catholic Reaction_, chap. ix. III
