Parmenides

Parmenides - Plato - Plato is a Classical Greek philosopher, mathematician, student of Socrates, writer of philosophical dialogues, and founder of the Academy in Athens, the first institution of higher learning in the Western world. Along with his mentor, Socrates, and his student, Aristotle, Plato helped to lay the foundations of Western philosophy and science.

Plato is one of the most important Western philosophers, exerting influence on virtually every figure in philosophy after him. His dialogue The Republic is known as the first comprehensive work on political philosophy. Plato also contributed foundationally to ethics, metaphysics, and epistemology. His student, Aristotle, is also an extremely influential philosopher and the tutor of Alexander the Great of Macedonia

Plato is widely considered a pivotal figure in the history of Ancient Greek and Western philosophy, along with his teacher, Socrates, and his most famous student, Aristotle. He has often been cited as one of the founders of Western religion and spirituality. The so-called neoplatonism of philosophers, such as Plotinus and Porphyry, greatly influenced Christianity through Church Fathers such as Augustine. Alfred North Whitehead once noted: "the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato."

Plato was an innovator of the written dialogue and dialectic forms in philosophy. Plato is also considered the founder of Western political philosophy. His most famous contribution is the theory of Forms known by pure reason, in which Plato presents a solution to the problem of universals known as Platonism (also ambiguously called either Platonic realism or Platonic idealism). He is also the namesake of Platonic love and the Platonic solids.

His own most decisive philosophical influences are usually thought to have been, along with Socrates, the pre-Socratics Pythagoras, Heraclitus and Parmenides, although few of his predecessors' works remain extant and much of what we know about these figures today derives from Plato himself. Unlike the work of nearly all of his contemporaries, Plato's entire body of work is believed to have survived intact for over 2,400 years. Although their popularity has fluctuated, Plato's works have consistently been read and
studied.

Little can be known about Plato's early life and education due to the very limited accounts. Plato came from one of the wealthiest and most politically active families in Athens. Ancient sources describe him as a bright though modest boy who excelled in his studies. His father contributed everything necessary to give to his son a good education, and Plato therefore must have been instructed in grammar, music, gymnastics and philosophy by some of the most distinguished teachers of his era.
