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]
