Time is the most valuable thing a man can spend. ”

Theophrastus (372 BC – 287 BC)
Greek philosopher


Theophrastus (GreekΘεόφραστος; c. 371 – c. 287 BC[1]), a Greek native of Eresos in Lesbos, was the successor toAristotle in the Peripatetic school. He came to Athens at a young age, and initially studied in Plato’s school. After Plato’s death he attached himself to Aristotle. Aristotle bequeathed to Theophrastus his writings, and designated him as his successor at the Lyceum. Theophrastus presided over the Peripatetic school for thirty-six years, during which time the school flourished greatly. After his death, the Athenians honoured him with a public funeral. His successor as head of the school was Strato of Lampsacus.

The interests of Theophrastus were wide-ranging, extending from biology and physics to ethics and metaphysics. His two surviving botanical works, Enquiry into Plants[2] and On the Causes of Plants, were an important influence on medievalscience. There are also surviving works On Moral CharactersOn SensationOn Stones, and fragments on Physics andMetaphysics all written in Greek. 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 onvirtue, and famously said that “life is ruled by fortune, not wisdom.”
