Paracelsus in fact exhibited in his person the union of a quack, a boastful and impudent pretender, with a considerable degree of natural sagacity and shrewdness. Such an union is not uncommon in the present day; but it was more properly in its place, when the cultivation of the faculties of the mind was more restricted than now, and the law of criticism of facts and evidence was nearly unknown. He took advantage of the credulity and love of wonder incident to the generality of our species; and, by dint of imposing on others, succeeded in no small degree in imposing on himself. His intemperance and arrogance of demeanour gave the suitable finish to his character. He therefore carefully cherished in those about him the idea that there was in him a kind of supernatural virtue, and that he had the agents of an invisible world at his command. In particular he gave out that he held conferences with a familiar or demon, whom for the convenience of consulting he was in the habit of carrying about with him in the hilt of his sword. CARDAN. Jerome Cardan, who was only a few years younger than Paracelsus, was a man of a very different character. He had considerable refinement and discrimination, and ranked among the first scholars of his day. He is however most of all distinguished for the Memoirs he has left us of his life, which are characterised by a frankness and unreserve which are almost without a parallel. He had undoubtedly a considerable spice of madness in his composition. He says of himself, that he was liable to extraordinary fits of abstraction and elevation of mind, which by their intenseness became so intolerable, that he gladly had recourse to very severe bodily pain by way of getting rid of them. That in such cases he would bite his lips till they bled, twist his fingers almost to dislocation, and whip his legs with rods, which he found a great relief to him. That he would talk purposely of subjects which he knew were particularly offensive to the company he was in; that he argued on any side of a subject, without caring whether he was right or wrong; and that he would spend whole nights in gaming, often venturing as the stake he played for, the furniture of his house, and his wife's jewels.
