Aristotle

384–322 BC · Greek philosopher and the first systematic biologist

Aristotle joined Plato’s Academy in Athens at about seventeen and stayed close to twenty years; later, barred as a foreigner from owning property, he rented the buildings known as the Lyceum and ran his own school there. Biology takes up a large share of his surviving work — History of Animals, Generation of Animals, Parts of Animals — and much of it rests on first-hand observation, including a stretch of zoological fieldwork around Lesbos. Parts of Animals is where he stops mid-treatise to argue that the humblest creature repays study, and this sentence is the hinge of that argument.
