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.
Philo of Larissa was a Greek philosopher. It is very probable that his actual name was Philio - with a second iota. He was a pupil of Clitomachus, whom he succeeded as head of the Academy. During the Mithridatic Wars which would see the destruction of the Academy, he travelled to Rome where Cicero heard him lecture. None of his writings survive. He was an Academic sceptic, like Clitomachus and Carneades before him, but he offered a more moderate view of skepticism than that of his teachers, permitting provisional beliefs without certainty.
Panaetius of Rhodes was an ancient Greek Stoic philosopher. He was a pupil of Diogenes of Babylon and Antipater of Tarsus in Athens, before moving to Rome where he did much to introduce Stoic doctrines to the city, thanks to the patronage of Scipio Aemilianus. After the death of Scipio in 129 BC, he returned to the Stoic school in Athens, and was its last undisputed scholarch. With Panaetius, Stoicism became much more eclectic. His most famous work was his On Duties, the principal source used by Cicero in his own work of the same name.
Middle Platonism is the modern name given to a stage in the development of Platonic philosophy, lasting from about 90 BC – when Antiochus of Ascalon rejected the scepticism of the new Academy – until the development of neoplatonism under Plotinus in the 3rd century. Middle Platonism absorbed many doctrines from the rival Peripatetic and Stoic schools. The pre-eminent philosopher in this period, Plutarch, defended the freedom of the will and the immortality of the soul. He sought to show that God, in creating the world, had transformed matter, as the receptacle of evil, into the divine soul of the world, where it continued to operate as the source of all evil. God is a transcendent being, who operates through divine intermediaries, which are the gods and daemons of popular religion. Numenius of Apamea combined Platonism with neopythagoreanism and other eastern philosophies, in a move which would prefigure the development of neoplatonism.
Platonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism has had a profound effect on Western thought. At the most fundamental level, Platonism affirms the existence of abstract objects, which are asserted to exist in a third realm distinct from both the sensible external world and from the internal world of consciousness, and is the opposite of nominalism. This can apply to properties, types, propositions, meanings, numbers, sets, truth values, and so on. Philosophers who affirm the existence of abstract objects are sometimes called Platonists; those who deny their existence are sometimes called nominalists. The terms "Platonism" and "nominalism" also have established senses in the history of philosophy. They denote positions that have little to do with the modern notion of an abstract object.
Antiochus of Ascalon was a 1st-century BC Platonist philosopher. He rejected skepticism, blended Stoic doctrines with Platonism, and was the first philosopher in the tradition of Middle Platonism.
The Academy, variously known as Plato's Academy, the Platonic Academy, and the Academic School, was founded at Athens by Plato circa 387 BC. Aristotle studied there for twenty years before founding his own school, the Lyceum. The Academy persisted throughout the Hellenistic period as a skeptical school, until coming to an end after the death of Philo of Larissa in 83 BC. The Platonic Academy was destroyed by the Roman dictator Sulla in 86 BC.
Ancient Roman philosophy is philosophy as it was practiced in the Roman Republic and its successor state, the Roman Empire. Roman philosophy includes not only philosophy written in Latin, but also philosophy written in Greek in the late Republic and Roman Empire. Important early Latin-language writers include Lucretius, Cicero, and Seneca the Younger. Greek was a popular language for writing about philosophy, so much so that the Roman Emperor Marcus Aurelius chose to write his Meditations in Greek.
Hellenistic philosophy is Ancient Greek philosophy corresponding to the Hellenistic period in Ancient Greece, from the death of Alexander the Great in 323 BC to the Battle of Actium in 31 BC. The dominant schools of this period were the Stoics, the Epicureans and the Skeptics.
Mnesarchus or Mnesarch, of Athens, was a Stoic philosopher, who lived c. 160 – c. 85 BC.
Diodotus was a Stoic philosopher, and was a friend of Cicero.

Eudorus of Alexandria was an ancient Greek philosopher, and a representative of Middle Platonism. He attempted to reconstruct Plato's philosophy in terms of Pythagoreanism.
Neoplatonism is a version of Platonic philosophy that emerged in the 3rd century AD against the background of Hellenistic philosophy and religion. The term does not encapsulate a set of ideas as much as a series of thinkers. Among the common ideas it maintains is monism, the doctrine that all of reality can be derived from a single principle, "the One".
De finibus bonorum et malorum is a Socratic dialogue by the Roman orator, politician, and Academic Skeptic philosopher Marcus Tullius Cicero. It consists of three dialogues, over five books, in which Cicero discusses the philosophical views of Epicureanism, Stoicism, and the Platonism of Antiochus of Ascalon. The treatise is structured so that each philosophical system is described in its own book, and then disputed in the following book. The book was developed in the summer of the year 45 BC, and was written over the course of about one and a half months. Together with the Tusculanae Quaestiones written shortly afterwards and the Academica, De finibus bonorum et malorum is one of the most extensive philosophical works of Cicero.
Academic skepticism refers to the skeptical period of the Academy dating from around 266 BCE, when Arcesilaus became scholarch, until around 90 BCE, when Antiochus of Ascalon rejected skepticism, although individual philosophers, such as Favorinus and his teacher Plutarch, continued to defend skepticism after this date. Unlike the existing school of skepticism, the Pyrrhonists, they maintained that knowledge of things is impossible. Ideas or notions are never true; nevertheless, there are degrees of plausibility, and hence degrees of belief, which allow one to act. The school was characterized by its attacks on the Stoics, particularly their dogma that convincing impressions led to true knowledge. The most important Academics were Arcesilaus, Carneades, and Philo of Larissa. The most extensive ancient source of information about Academic skepticism is Academica, written by the Academic skeptic philosopher Cicero.
Many interpreters of Plato held that his writings contain passages with double meanings, called allegories, symbols, or myths, that give the dialogues layers of figurative meaning in addition to their usual literal meaning. These allegorical interpretations of Plato were dominant for more than fifteen hundred years, from about the 1st century CE through the Renaissance and into the 18th century, and were advocated by major Platonist philosophers such as Plotinus, Porphyry, Syrianus, Proclus, and Marsilio Ficino. Beginning with Philo of Alexandria, these views influenced the Jewish, Christian, and Islamic interpretation of these religions' respective sacred scriptures. They spread widely during the Renaissance and contributed to the fashion for allegory among poets such as Dante Alighieri, Edmund Spenser, and William Shakespeare.
On Passions, also translated as On Emotions or On Affections, is a work by the Greek Stoic philosopher Chrysippus dating from the 3rd-century BCE. The book has not survived intact, but around seventy fragments from the work survive in a polemic written against it in the 2nd-century CE by the philosopher-physician Galen. In addition Cicero summarises substantial portions of the work in his 1st-century BCE work Tusculan Disputations. On Passions consisted of four books; of which the first three discussed the Stoic theory of emotions and the fourth book discussed therapy and had a separate title—Therapeutics. Most surviving quotations come from Books 1 and 4, although Galen also provides an account of Book 2 drawn from the 1st-century BCE Stoic philosopher Posidonius. Little or nothing is known about Book 3.
The Academica is work in a fragmentary state written by the Academic Skeptic philosopher Cicero published in two editions. The first edition is referred to as the Academica Priora. It was released in May 45 BCE and comprised two books, known as the Catulus and the Lucullus. The Catulus has been lost. Cicero subsequently extensively revised and expanded the work, releasing a second edition comprising four books. Except for part of Book 1 and 36 fragments, all of the second edition has been lost. The second edition is referred to as Academica Posteriora or Academici Libri or Varro.
Aristus was a philosopher of ancient Greece from Ascalon (Ashkelon), aligned with the "Academic" school of philosophy, also known as Platonism. He was the pupil of and later successor to his brother, the more famous and renowned Academic philosopher Antiochus of Ascalon, and was generally considered to be the inferior philosopher.
