Paracelsus, as presented in the poem, is a man of pre-eminent genius, passionate intellect, and inordinate intellectual ambition. If it is meant that he should be the type of the modern man of science, Browning has missed his mark, for Paracelsus is in fact almost as much the poet as the man of science; but it is true that the cautious habits of the inductive student of nature were rare among the enthusiastic speculators of Renaissance days, and the Italian successor of Paracelsus—Giordano Bruno—was in reality, in large measure, what Browning has here conceived and exhibited. Paracelsus is a great revolutionary spirit in an epoch of intellectual revolution; it is as much his task to destroy as to build up; he has broken with the past, and gazes with wild-eyed hopes into the future, expecting the era of intellectual liberty to dawn suddenly with the year One, and seeing in himself the protagonist of revolution. Such men as Paracelsus, whether their sphere be in the political, the religious, or the intellectual world, are men of faith; a task has been laid on each of them; a summons, a divine mandate, has been heard. But is the summons authentic? is the mandate indeed divine? In the quiet garden at Wuerzburg, while the autumn sun sinks behind St Saviour’s spire, Festus—the faithful Horatio to this Hamlet of science—puts his questions and raises his doubts first as to the end and aim of Paracelsus, his aspiration towards absolute knowledge, and secondly, as to the means proposed for its attainment—means which reject the service of all predecessors in the paths of knowledge; which depart so widely from the methods of his contemporaries; which seek for truth through strange and casual revelations; which leave so much to chance. Very nobly has Browning represented the overmastering force of that faith which genius has in itself, and which indeed is needed to sustain it in the struggle with an incredulous or indifferent world. The end itself is justified by the mandate
