By the independence of his mental processes he was thrown quite upon his own resources, and his nature, already dignified and reserved, was made more introspective and self-conscious. In this way he developed strains of vanity and egotism which led him at times to the bombastic self-laudation of a Paracelsus. He had nothing but disgust for the common people and the sort of scholars (pedants) whom they admired. The vulgar mind was more influenced by sophisms, by appearance, by failure to distinguish between the shadow and the substance. Take but two or three of Bruno's conceptions:—
He perhaps first during the middle ages taught the transformation of lower into higher organisms, following the Greeks who first enunciated the doctrine of evolution, which it remained for Darwin and Wallace to edit and illustrate as that law of the organic continuity of life, which we call evolution. He further wrote of the human hand as a factor in the evolution of the human race, in a way which should have commended him to the author of the Bridgewater treatise. He wrote of the changes on the earth's surface brought about by natural processes, which have changed not only the external configuration of the same but the fate and destiny of nations; of the identity of matter throughout the universe; of the universal movement of matter. Long before Lessing he showed how myths may contain the germs of great truths, and should be regarded as indications thereof. In this way, he told us, the Bible was to be regarded, holding its more or less historical statements to be quite subordinate to its moral teachings.
When we realize how to such highly developed reasoning powers as Bruno possessed, were added a phenomenal memory, a tremendous power of assimilation, a developed imagination, a poetic nature, the gift of easy and accurate speech and a temperament easily excited to fervor in attack or defense, we may the better appreciate his dominating greatness as well as his trifling weakness; the former being entirely to his own credit while the latter are ascribed largely to the faults of his time, and the fact that he was really living far ahead of his day and generation. He was not only the forerunner of modern science, he was the prototype of the modern biblical critic, foreshadowing the modern higher criticism, albeit in veiled terms, and as a matter of esoteric teaching; because the biblical critic of those days was burned at the stake, while to-day he is barely ostracized by the shallow and narrow minded, with whom he has at best nothing mentally in common. So much have four centuries of labor and vicarious suffering accomplished for the emancipation of the human mind.
Bruno had a creed, but it was too simple for his times. He rejected certain orthodox dogmas, (e. g. the Trinity, the Immaculate Conception) which commend themselves still less to the emancipated and cultivated minds of to-day. He absolutely rejected authority, which was a step toward reason comparable to the freeing of the slaves or serfs. He evolved a theory of evolution from a priori concepts, which it remained for Darwin to complete and demonstrate. He believed in the natural history of religions. His motives were of the loftiest, though his methods were not always those of to-day. He believed that the essence of truth inhered in those differences which kept men apart, and still sever them. He believed the law of love and that it sprang from God, which is the Father of All, that it was in harmony with nature, and that by love we may be transformed into something of His likeness. As Bruno himself says:—"This is the religion, above controversy or dispute, which I observe from the belief of my own mind, and from the custom of my fatherland and my race." (McIntyre, p. 110).
And yet this sublime man was burned as a heretic! Let us stop when we hereafter pass through the Campo dei Fiori, as I have done many a time, and take off our hats to the memory of this great man, who, while small in some human traits, yet was the greatest thinker in Italy during the sixteenth century, whose memory may help us to forget some of the hypocrisies and cant so generally prevalent during the age which and among the men who condemned him. Let us also thank God that there is no Tribunal of the Inquisition to-day, to pass misguided judgment upon us for having gone further than Bruno ever dreamed, though along the same lines, and to condemn us therefore to the Flames.
This paper has already been prolonged, perhaps tiresomely, nevertheless I cannot refrain from quoting a few paragraphs from that most versatile student of this period, Symonds, whose estimate of Bruno is as follows:—(Renaissance in Italy; Catholic Reaction, II Chap. ix).
"Bruno appears before us as the man who most vitally and comprehensively grasped the leading tendencies of his age in their intellectual essence. He left behind him the mediaeval conception of an extra-mundane God, creating a finite world, of which this globe is the center, and the principal episode in the history of which is the series of events from the Fall, through the Incarnation and Crucifixion, to the Last Judgment. He substituted the conception of an ever-living, ever-acting, ever-self-effectuating God, immanent in an infinite universe, to the contemplation of whose attributes the mind of man ascends by the study of Nature and interrogation of his conscience.
"Bolder even than Copernicus, and nearer in his intuition to the truth, he denied that the universe had "flaming walls" or any walls at all. That "immaginata circonferenza," "quella margine immaginata del cielo," on which antique science and Christian theology alike reposed, was the object of his ceaseless satire, his oft-repeated polemic. What, then, rendered Bruno the precursor of modern thought in its various manifestations, was that he grasped the fundamental truth upon which modern science rests, and foresaw the conclusions which must be drawn from it. He speculated boldly, incoherently, vehemently; but he speculated with a clear conception of the universe, as we still apprehend it. Through the course of three centuries we have been engaged in verifying the guesses, deepening, broadening and solidifying the hypotheses, which Bruno's extension of the Copernican theory, and his application of it to pure thought suggested to his penetrating and audacious intellect."
Bruno was convinced that religion in its higher essence would not sufferer from the new philosophy. Larger horizons extended before the human intellect. The soul expanded in more exhilarating regions than the old theologies had offered.
