His writings cover a broad range of subjects spanning the natural sciences, philosophy, linguistics, economics, politics, psychology, and the arts. As the founder of the Peripatetic school of philosophy in the Lyceum in Athens, he began the wider Aristotelian tradition that followed, which set the groundwork for the development of modern science.

Plato ( ; Greek: , ; born  BC, died 348/347 BC) was an ancient Greek philosopher of Classical Athens who is most commonly considered the foundational thinker of the Western philosophical tradition.

Socrates (; ; – 399 BC) was an ancient Greek philosopher from Classical Athens, perhaps the first Western moral philosopher, and a major inspiration on his student Plato, who largely founded the tradition of Western philosophy. An enigmatic figure, Socrates authored no texts and is known mainly through the posthumous accounts of classical writers, particularly his students Plato and Xenophon. These accounts are written as dialogues, in which Socrates and his interlocutors examine a subject in the style of question and answer; they gave rise to the Socratic dialogue literary genre.

Epicurus (, ; ; 341–270 BC) was an ancient Greek philosopher who founded Epicureanism, a highly influential school of philosophy; it asserted that philosophy's purpose is to attain as well as to help others attain tranquil lives, characterized by freedom from fear and the absence of pain.

Protagoras ( ; ; ) was a pre-Socratic Greek philosopher and rhetorical theorist. He is numbered as one of the sophists by Plato. In his dialogue Protagoras, Plato credits him with inventing the role of the professional sophist.

Theophrastus (; ; c. 371 – c. 287 BC) was an ancient Greek philosopher and naturalist. A native of Eresos in Lesbos, he was Aristotle's close colleague and successor as head of the Lyceum, the Peripatetic school of philosophy in Athens. Theophrastus wrote numerous treatises across all areas of philosophy, working to support, improve, expand, and develop the Aristotelian system. He made significant contributions to various fields, including ethics, metaphysics, botany, and natural history. Often considered the "father of botany" for his groundbreaking works "Enquiry into Plants" () and "On the

Greek philosopher, founder of Stoicism

Antisthenes (; , ; 446 366 BCE) was a Greek philosopher and a pupil of Socrates. Antisthenes first learned rhetoric under Gorgias before becoming an ardent disciple of Socrates. He adopted and developed the ethical side of Socrates' teachings, advocating an ascetic life lived in accordance with virtue. Later writers regarded him as the founder of Cynic philosophy.

Aristippus of Cyrene (; ; c. 435 – c. 356 BCE) was a hedonistic Greek philosopher and the founder of the Cyrenaic school of philosophy. He was a pupil of Socrates, but adopted a different philosophical outlook, teaching that the goal of life was to seek pleasure by adapting circumstances to oneself and by maintaining proper control over both adversity and prosperity. His view that pleasure is the only good came to be called ethical hedonism. Due to the ideological and philosophical differences between Socrates and himself, Aristippus faced backlash from Socrates and many of his fellow pupils.

Chrysippus of Soli (; , ; ) was a Greek Stoic philosopher. He was a native of Soli, Cilicia, but moved to Athens as a young man, where he became a pupil of the Stoic philosopher Cleanthes. When Cleanthes died, around 230 BC, Chrysippus became the third head of the Stoic school. A prolific writer, Chrysippus expanded the fundamental doctrines of Cleanthes' mentor Zeno of Citium, the founder and first head of the school, which earned him the title of the Second Founder of Stoicism.
