Theaetetus

"The Theaetetus" by Plato is a philosophical dialogue likely written in the late 4th century BC. The work explores the nature of knowledge through an exchange between Socrates, the protagonist, and a young mathematician named Theaetetus, as they dissect various definitions and theories regarding the essence of knowledge. At the start of the dialogue, we learn of Theaetetus's unfortunate condition, having been wounded and brought back from battle, which sets a reflective tone surrounding his potential. Socrates directly engages Theaetetus, leading him in a dialectical examination that begins with the definition of knowledge as "sensible perception," drawing on Protagorean thought. The conversation unfolds into deeper explorations involving perception, opinion, and falsehoods, revealing the complexities behind defining knowledge itself, while showcasing Socrates’s midwifery-like role in drawing out ideas from Theaetetus. This opening section sets the foundation for a rigorous philosophical inquiry that probes the limits of human understanding and cognition. (This is an automatically generated summary.)

Plato, born Aristocles, was an ancient Greek philosopher of the Classical period who is considered a foundational thinker in Western philosophy and an innovator of the written dialogue and dialectic forms. He raised problems for what became all the major areas of both theoretical philosophy and practical philosophy, and was the founder of the Platonic Academy, a philosophical school in Athens where Plato taught the doctrines that would later become known as Platonism.
