Alike in the details of his propaganda and in the temper of his utterance, Bruno expresses from first to last the spirit of freethought and free speech. Libertas philosophica[205] is the breath of his nostrils; and by his life and his death alike he upholds the ideal for men as no other before him did. The wariness of Rabelais and the non-committal skepticism of Montaigne are alike alien to him; he is too lacking in reticence, too explosive, to give due heed even to the common-sense amenities of life, much more to hedge his meaning with safeguarding qualifications. And it was doubtless as much by the contagion of his mood as by his lore that he impressed men.
His personal and literary influence was probably most powerful in respect of his eager propaganda of the Copernican doctrine, which he of his own force vitally expanded and made part of a pantheistic conception of the universe.[206] Where Copernicus adhered by implication to the idea of an external and limitary sphere—the last of the eight of the Ptolemaic theory—Bruno reverted boldly to the doctrine of Anaximandros, and declared firmly for the infinity of space and of the series of the worlds. In regard to biology he makes an equivalent advance, starting from the thought of Empedocles and Lucretius, and substituting an idea of natural selection for that of creative providence.[207] The conception is definitely thought out, and marks him as one of the renovators of scientific no less than of philosophic thought for the modern world; though the special paralysis of science under Christian theology kept his ideas on this side pretty much a dead letter for his own day. And indeed it was to the universal and not the particular that his thought chiefly and most enthusiastically turned. A philosophic poet rather than a philosopher or man of science, he yet set abroad for the modern world that conception of the physical infinity of the universe which, once psychologically assimilated, makes an end of the medieval theory of things. On this head he was eagerly affirmative; and the merely Pyrrhonic skeptics he assailed as he did the “asinine” orthodox, though he insisted on doubt as the beginning of wisdom.
Of his extensive literary output not much is stamped with lasting scientific fitness or literary charm; and some of his treatises, as those on mnemonics, have no more value than the product of his didactic model, Raymond Lully. As a writer he is at his best in the sweeping expatiation of his more general philosophic treatises, where he attains a lifting ardour of inspiration, a fervour of soaring outlook, that puts him in the front rank of the thinkers of his age. And if his literary character is at times open to severe criticism in respect of his lack of balance, sobriety, and self-command, his final courage atones for such shortcomings.
His case, indeed, serves to remind us that at certain junctures it is only the unbalanced types that aid humanity’s advance. The perfectly prudent and self-sufficing man does not achieve revolutions, does not revolt against tyrannies; he wisely adapts himself and subsists, letting the evil prevail as it may. It is the more impatient and unreticent, the eager and hot-brained—in a word, the faulty—who clash with oppression and break a way for quieter spirits through the hedges of enthroned authority. The serenely contemplative spirit is rather a possession than a possessor for his fellows; he may inform and enlighten, but is not in himself a countering or inspiriting force: a Shelley avails more than a Goethe against tyrannous power. And it may be that the battling enthusiast in his own way wins liberation for himself from “fear of fortune and death,” as he wins for others liberty of action.[208] Even such a liberator, bearing other men’s griefs and taking stripes that they might be kept whole, was Bruno.
And though he quailed at the first shock of capture and torture, when the end came he vindicated human nature as worthily as could any quietist. It was a long-drawn test. Charged on the traitor’s testimony with many “blasphemies,” he denied them all,[209] but stood to his published writings[210] and vividly expounded his theories,[211] professing in the usual manner to believe in conformity with the Church’s teachings, whatever he might write on philosophy. It is impossible to trust the Inquisition records as to his words of self-humiliation;[212] though on the other hand no blame can rationally attach to anyone who, in his place, should try to deceive such enemies, morally on a level with hostile savages. It is certain that the Inquisitors frequently wrung recantations by torture.[213]
What is historically certain is that Bruno was not released, but sent on to Rome, and was kept there in prison for seven years. He was not the sort of heretic likely to be released; though the fact of his being a Dominican, and the desire to maintain the Church’s intellectual credit, delayed so long his execution. Certainly not an atheist (he called himself in several of his book-titles Philotheus; he consigns insano ateismo to perdition;[214] and his quasi-pantheism or monism often lapses into theistic modes),[215] he yet was from first to last essentially though not professedly anti-Christian in his view of the universe. If the Church had cause to fear any philosophic teaching, it was his, preached with the ardour of a prophet and the eloquence of a poet. His doctrine that the worlds in space are innumerable was as offensive to orthodox ears as his specific negations of Christian dogma, outgoing as it did the later idea of Kepler and Galileo. He had, moreover, finally refused to make any fresh recantation; and the only detailed document extant concerning his final trial describes him as saying to his judges: “With more fear, perchance, do you pass sentence on me than I receive it.”[216] According to all accessible records, he was burned alive at Rome in February, 1600, in the Field of Flowers, near where his statue now stands. As was probably customary, they tied his tongue before leading him to the stake, lest he should speak to the people;[217] and his martyrdom was an edifying spectacle for the vast multitude of pilgrims who had come from all parts of Christendom for the jubilee of the pope.[218] At the stake, when he was at the point of death, there was duly presented to him the crucifix, and he duly put it aside.
An attempt has been made by Professor Desdouits in a pamphlet (La légende tragique de Jordano Bruno; Paris, 1885) to show that there is no evidence that Bruno was burned; and an anonymous writer in the Scottish Review (October, 1888, Art. II), rabidly hostile to Bruno, has maintained the same proposition. Doubt on the subject dates from Bayle. Its main ground is the fewness of the documentary records, of which, further, the genuineness is now called in question. But no good reason is shown for doubting them. They are three.
1. The Latin letter of Gaspar Schopp (Scioppius), dated February 17, 1600, is an eye-witness’s account of the sentencing and burning of Bruno at that date. (See it in full, in the original Latin, in Berti, p. 461 sq., and in App. V to Frith, Life of Bruno, and partly translated in Prof. Adamson’s lectures, as cited. It was rep. by Struvius in his Acta Literaria, tom. v, and by La Croze in his Entretiens sur divers sujets in 1711, p. 287.) It was not printed till 1621, but the grounds urged for its rejection are totally inadequate, and involve assumptions, which are themselves entirely unproved, as to what Scioppius was likely to do. Finally, no intelligible reason is suggested for the forging of such a document. The remarks of Prof. Desdouits on this head have no force whatever. The writer in the Scottish Review (p. 263, and note) suggests as “at least as possible an hypothesis as any other that he [Bruno] was the author of the forged accounts of his own death.” Comment is unnecessary.
2. There are preserved two extracts from Roman news-letters (Avvisi) of the time; one, dated February 12, 1600, commenting on the case; the other, dated February 19, relating the execution on the 17th. (See both in S. R., pp. 264–65. They were first printed by Berti in Documenti intorno a Giordano Bruno, Rome, 1880, and are reprinted in his Vita, ed. 1889, cap. xix; also by Levi, as cited.) Against these testimonies the sole plea is that they mis-state Bruno’s opinions and the duration of his imprisonment—a test which would reduce to mythology the contents of most newspapers in our own day. The writer in the Scottish Review makes the suicidal suggestion that, inasmuch as the errors as to dates occur in Schopp’s letter, “the so-called Schopp was fabricated from these notices, or they from Schopp”—thus admitting one to be historical.
3. There has been found, by a Catholic investigator, a double entry in the books of the Lay Brotherhood of San Giovanni Decollato, whose function was to minister to prisoners under capital sentence, giving a circumstantial account of Bruno’s execution. (See it in S. R., pp. 266, 269, 270.) In this case, the main entry being dated “1600. Thursday. February 16th,” the anonymous writer argues that “the whole thing resolves itself into a make-up,” because February 16 was the Wednesday. The entry refers to the procedure of the Wednesday night and the Thursday morning; and such an error could easily occur in any case. Whatever may be one day proved, the cavils thus far count for nothing. All the while, the records as to Bruno remain in the hands of the Catholic authorities; but, despite the discredit constantly cast on the Church on the score of Bruno’s execution, they offer no official denial of the common statement; while they do officially admit (S. R., p. 252) that on February 8 Bruno was sentenced as an “obstinate heretic,” and “given over to the Secular Court.” On the other hand, the episode is well vouched; and the argument from the silence of ambassadors’ letters is so far void. No pretence is made of tracing Bruno anywhere after February, 1600.
