Theophrastus
Greek philosopher (c.371-c.287 BC)
Biography
Theophrastus (c. 371-287 BC) was an ancient Greek philosopher and naturalist known for his influential work in natural science and philosophy. He was born Tyrtamos in Eresos, on the island of Lesbos, and later took the name Theophrastus, meaning 'divine speaker,' reportedly given by Aristotle, reflecting his exceptional speaking skills. This ability helped him succeed as a teacher and philosopher.
He went to Athens as a young man and studied at Plato's Academy before becoming closely associated with Aristotle. When Aristotle had to leave Athens in 323 BC after Alexander the Great's death, Theophrastus became the head of the Lyceum and the Peripatetic school. He led for thirty-six years, during which the school grew significantly, attracting students from all over Greece and becoming a leading center of learning.
Theophrastus made important contributions to botany, earning the title of the father of botanical science. His major works, 'Enquiry into Plants' and 'On the Causes of Plants,' recorded over 500 plant species. He established basic principles of plant classification, growth, and reproduction, going beyond description to explore the causes of plant phenomena. His studies covered plant anatomy, reproduction, distribution, and medicinal properties.
In addition to botany, Theophrastus wrote on ethics, metaphysics, physics, and psychology. His 'Characters' depicted thirty personality types in vivid and sometimes humorous sketches, influencing literature for centuries. His writings 'On Sense Perception' and 'Metaphysics' engaged with Aristotelian theories while also offering his own ideas, showing his skill in both preserving and advancing Aristotelian thought.
Theophrastus died in Athens around 287 BC at about eighty-five years old. The Athenians gave him a public funeral, showing their respect for him. His death marked the end of an era for the Peripatetic school, but his influence continued through his successor Strato of Lampsacus and the many students he had taught.
Before Fame
Theophrastus grew up in an intellectually rich environment on Lesbos at a time when Greek philosophy was shifting from earlier metaphysical ideas to more hands-on studies of nature. He probably started with the usual Greek subjects like rhetoric, math, and literature before making the big move to Athens, the heartbeat of intellectual life in Greece.
He first studied at Plato's Academy, which gave him a grounding in philosophical techniques and metaphysical thought. But his real growth began when he joined Aristotle’s group, where he found a mentor whose organized way of studying nature matched his own interest in observation and classification. This mentorship was crucial, as Aristotle's impact guided Theophrastus's methods and pushed him to research botanical and ethical questions on his own.
