テオフラストゥス、Theophrastus (Greek: Θεόφραστος; 371 – c. 287 BC), a native of Eressos in Lesbos,[1] was the successor of Aristotle in the Peripatetic school. His interests were wide-ranging, extending from biology and physics to ethics and metaphysics. His two surviving botanical works, Enquiry into Plants and On the Causes of Plants, were an important influence on medieval science. There are also surviving works On Moral Characters, On Sensation, On Stones, and fragments on Physics and Metaphysics. In philosophy, he studied grammar and language, and continued Aristotle's work on logic. He also regarded space as the mere arrangement and position of bodies, time as an accident of motion, and motion as a necessary consequence of all activity. In ethics, he regarded happiness as depending on external influences as well as on virtue, and famously said that "life is ruled by fortune, not wisdom."wikipedia |
