forfeited the respect of his colleagues. He devoted a large volume
to the relations between the planets and the human face. He was as
expert and absurd as Freud in interpreting dreams, and as firm a
believer in guardian angels as Fra Angelico. Yet he named, as the
ten greatest intellects in history, men not overwhelmingly
Christian: Archimedes, Aristotle, Euclid, Apollonius of Perga,
Archytas of Tarentum, al-Khwarizmi, al-Kindi, Gebir, Duns Scotus,
and Richard Swineshead- all scientists except Duns. Cardan made a
hundred enemies, invited a thousand calumnies, married miserably,
and fought unsuccessfully to save his eldest son from being executed
for poisoning an unfaithful wife. In 1570 he moved to Rome. He was
arrested there for debt or heresy or both; but Gregory XIII released
and pensioned him.
At seventy-four he wrote De vita propria liber ( A Book of My
Own Life )- one of three remarkable autobiographies composed in this
period in Italy. With almost the garrulousness and fidelity of
Montaigne, he analyzes himself- body, mind, character, habits, likes
and dislikes, virtues and vices, honors and dishonors, errors and
prophecies, illnesses, eccentricities, and dreams. He accuses
himself of obstinacy, bitterness, unsociability, hasty judgment,
pugnacity, cheating at gambling, vengefulness, and mentions "the
debaucheries of the Sardanapalian life I led in the year when I was
rector of the University of Padua." `052316 He lists "things in
which I feel that I have failed"- especially the proper rearing of his
sons. But he lists also seventy-three books that mention him; tells of
his many successful cures and predictions, and his invincibility in
debate. He bemoans the persecutions to which he was subjected, and the
hazards "that beset me on account of my unorthodox views." `052317
He asks himself, "What animal do I find more treacherous, vile, and
deceitful than man?" and offers no reply. But he records many things
that give him happiness, including change, food, drink, sailing,
music, puppies, cats, continence, and sleep. "Of all ends that man may
attain, none seems more worthy or more pleasing than the recognition
of truth." `052318 His favorite pursuit was medicine, in which he
achieved many surprising cures.
Medicine was the only science that made any significant progress
in this period of Italy's decline. The greatest scientists of the
