Fazio took no trouble to teach his son Latin,[25] though the learned language would have been just as necessary for the study of jurisprudence as for any other liberal calling, and Jerome did not begin to study it systematically till he was past nineteen years of age. Through some whim or prejudice the old man refused for some time to allow the boy to go to the University, and when at last he gave his consent he still fought hard to compel Jerome to qualify himself in jurisprudence; but here he found himself at issue with a will more stubborn than his own. Cardan writes: "From my earliest youth I let every action of mine be regulated in view of the after course of my life, and I deemed that as a career medicine would serve my purpose far better than law, being more appropriate for the end I had in view, of greater interest to the world at large, and likely to last as long as time itself. At the same time I regarded it as a study which embodied the nobler principles, and rested upon the ground of reason (that is upon the eternal laws of Nature) rather than upon the sanction of human opinion. On this account I took up medicine rather than jurisprudence, nay I almost entirely cast aside, or even fled from the company of those friends of mine who followed the law, rejecting at the same time wealth and power and honour. My father, when he heard that I had abandoned the study of law to follow philosophy, wept in my presence, and grieved amain that I would not settle down to the study of his own subject. He deemed it the more salutary discipline--proofs of which opinion he would often bring forward out of Aristotle--that it was better adapted for the acquisition of power and riches; and that it would help me more efficiently in restoring the fortunes of our house. He perceived moreover that the office of teaching in the schools of the city, together with its accompanying salary of a hundred crowns which he had enjoyed for so many years, would not be handed on to me, as he had hoped, and he saw that a stranger would succeed to the same. Nor was that commentary of his destined ever to see the light or to be illustrated by my notes. Earlier in life he had nourished a hope that his name might become illustrious as the emendator of the 'Commentaries of John, Archbishop of Canterbury on Optics and Perspective.'[26] Indeed the following verses were printed thereanent: 'Hoc Cardana viro gaudet domus: omnia novit Unus: habent nullum saecula nostra parem.'
