Ammonius Hermiae was a Greek philosopher from Alexandria in the eastern Roman empire during Late Antiquity. A Neoplatonist, he was the son of the philosophers Hermias and Aedesia, the brother of Heliodorus of Alexandria and the grandson of Syrianus. Ammonius was a pupil of Proclus in Roman Athens, and taught at Alexandria for most of his life, having obtained a public chair in the 470s.
Anaxagoras was a Pre-Socratic Greek philosopher. Born in Clazomenae at a time when Asia Minor was under the control of the Persian Empire, Anaxagoras came to Athens. In later life he was charged with impiety and went into exile in Lampsacus.
Anaximenes of Miletus was an Ancient Greek, Pre-Socratic philosopher from Miletus in Anatolia. He was the last of the three philosophers of the Milesian School, after Thales and Anaximander. These three are regarded by historians as the first philosophers of the Western world. Anaximenes is known for his belief that air is the arche, or the basic element of the universe from which all things are created. Little is known of Anaximenes' life and work, as all of his original texts are lost. Historians and philosophers have reconstructed information about Anaximenes by interpreting texts about him by later writers. All three Milesian philosophers were monists who believed in a single foundational source of everything: Anaximenes believed it to be air, while Thales and Anaximander believed it to be water and an undefined infinity, respectively. It is generally accepted that Anaximenes was instructed by Anaximander, and many of their philosophical ideas are similar. While Anaximenes was the preeminent Milesian philosopher in Ancient Greece, he is often given lower importance than the others in the modern day.
Empedocles was a Greek pre-Socratic philosopher and a native citizen of Akragas, a Greek city in Sicily. Empedocles' philosophy is best known for originating the cosmogonic theory of the four classical elements. He also proposed forces he called Love and Strife which would mix and separate the elements, respectively.
Heraclitus was an ancient Greek pre-Socratic philosopher from the city of Ephesus, which was then part of the Persian Empire. He exerts a wide influence on ancient and modern Western philosophy, including through the works of Plato, Aristotle, Hegel, and Heidegger.
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.
Parmenides of Elea was a pre-Socratic Greek philosopher from Elea in Magna Graecia.
Pre-Socratic philosophy, also known as Early Greek Philosophy, is ancient Greek philosophy before Socrates. Pre-Socratic philosophers were mostly interested in cosmology, the beginning and the substance of the universe, but the inquiries of these early philosophers spanned the workings of the natural world as well as human society, ethics, and religion. They sought explanations based on natural law rather than the actions of gods. Their work and writing has been almost entirely lost. Knowledge of their views comes from testimonia, i.e. later authors' discussions of the work of pre-Socratics. Philosophy found fertile ground in the ancient Greek world because of the close ties with neighboring civilizations and the rise of autonomous civil entities, poleis.
Ancient Greek philosophy arose in the 6th century BC. Philosophy was used to make sense of the world using reason. It dealt with a wide variety of subjects, including astronomy, epistemology, mathematics, political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric and aesthetics. Greek philosophy continued throughout the Hellenistic period and later evolved into Roman philosophy.
Eduard Gottlob Zeller was a German philosopher and Protestant theologian of the Tübingen School of theology. He was well known for his writings on Ancient Greek philosophy, especially Pre-Socratic Philosophy, and most of all for his celebrated, multi-volume historical treatise The Philosophy of Greeks in their Historical Development (1844–52). Zeller was also a central figure in the revival of neo-Kantianism.
In Ancient Greek philosophy, techne is a philosophical concept that refers to making or doing. Today, while the Ancient Greek definition of techne is similar to the modern definition and use of "practical knowledge", techne can include various fields such as mathematics, geometry, medicine, shoemaking, rhetoric, philosophy, music, and astronomy.
Gregory Vlastos was a preeminent scholar of ancient philosophy, and author of many works on Plato and Socrates. He transformed the analysis of classical philosophy by applying techniques of modern analytic philosophy to restate and evaluate the views of Socrates and Plato.
Nous, from Greek: νοῦς, is a concept from classical philosophy, sometimes equated to intellect or intelligence, for the faculty of the human mind necessary for understanding what is true or real.

It catalogues both pagan beliefs and 33 gnostic Christian systems deemed heretical by Hippolytus, making it a major source of information on contemporary opponents of Christian orthodoxy as understood today.
