Girolamo Cardano Quotes on Knowledge

Girolamo Cardano (1501–1576), the Milanese physician, mathematician, and natural philosopher, was one of the most prolific Renaissance polymaths and the author of the autobiographical De Vita Propria. The major philosophical works — De Subtilitate (1550) and De Rerum Varietate (1557) — present a Renaissance natural philosophy in which mathematical, astrological, medical, and metaphysical inquiry are systematically interconnected, and the Liber de ludo aleae gave the first systematic treatment of probability. The framework exemplifies the polymathic conception of natural knowledge that the seventeenth century would partition into the specialized disciplines of the modern sciences.
