Set immediately prior to the trial and execution of Socrates in 399 BC, Theaetetus shows the great philosopher considering the nature of knowledge itself, in a debate with the geometrician Theodorus and his young follower Theaetetus. Their dialogue covers many questions, such as: is knowledge purely subjective, composed of the ever-changing flow of impressions we receive from the outside world? Is it better thought of as "true belief"? Or is it, as many modern philosophers argue, "justified true belief," in which the belief is supported by argument or evidence? With skill and eloquence, Socrates guides the debate, drawing out the implications of these theories and subjecting them to merciless and mesmerising criticism. One of the founding works of epistemology, this profound discussion of the problem of knowledge continues to intrigue and inspire.

Plato, with Socrates and Aristotle, is the founder of the Western intellectual tradition. Like his mentor Socrates, he was essentially a practical philosopher who found the abstract theory and visionary schemes of many contemporary thinkers misguided and sterile. He was born about 429 BCE in Athens, the son of a prominent family that had long been involved in the city's politics. Extremely little survives of the history of Plato's youth, but he was raised in the shadow of the great Peloponnesian War, and its influence must have caused him to reject the political career open to him and to become a follower of the brilliantly unorthodox Socrates, the self-proclaimed "gadfly" of Athens.
Socrates' death in 399 BCE turned Plato forever from politics, and in the next decade he wrote his first dialogues, among them Apology and Euthyphro. At age 40, Plato visited Italy and Syracuse, and upon his return he founded the Academy-Europe's first university—in a sacred park on the outskirts of Athens. The Academy survived for a millennium, finally closed by the emperor Justinian in 529. Plato hoped his school would train its pupils to carry out a life of service and to investigate questions of science and mathematics. Plato's old age was probably devoted to teaching and writing, he died in Athens in 348 BCE.
