Clitomachus (philosopher)Clitomachus or Cleitomachus (Κλειτόμαχος, Kleitómakhos; 187/6–110/9 BC) was a Greek philosopher, originally from Carthage, who came to Athens in 163/2 BC and studied philosophy under Carneades. He became head of the Academy around 127/6 BC. He was an Academic skeptic like his master. Nothing survives of his writings, which were dedicated to making known the views of Carneades, but Cicero made use of them for some of his works. Clitomachus was born in Carthage in 187/6 BC as Hasdrubal (Ἀσδρούβας, Hasdroúbas; 𐤏𐤆𐤓𐤁𐤏𐤋, ʿAzrubaʿal, "Help of Baal").
PlutarchPlutarch (ˈpluːtɑrk; Πλούταρχος, Ploútarchos; ˈplúːtarkhos; AD 46 – after AD 119) was a Greek Middle Platonist philosopher, historian, biographer, essayist, and priest at the Temple of Apollo in Delphi. He is known primarily for his Parallel Lives, a series of biographies of illustrious Greeks and Romans, and Moralia, a collection of essays and speeches. Upon becoming a Roman citizen, he was possibly named Lucius Mestrius Plutarchus (Λούκιος Μέστριος Πλούταρχος).
AenesidemusAenesidemus (Αἰνησίδημος or Αἰνεσίδημος) was a 1st-century BC Greek Pyrrhonist philosopher from Knossos who revived the doctrines of Pyrrho and introduced ten skeptical "modes" (tropai) for the suspension of judgment. He broke with the Academic Skepticism that was predominant in his time, synthesizing the teachings of Heraclitus and Timon of Phlius with philosophical skepticism. Although his primary work, the Pyrrhonian Discourses, has been lost, an outline of the work survives from the later Byzantine empire, and the description of the modes has been preserved by few ancient sources.
Philosophical skepticismPhilosophical skepticism (UK spelling: scepticism; from Greek σκέψις skepsis, "inquiry") is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence.
PlatonismPlatonism is the philosophy of Plato and philosophical systems closely derived from it, though contemporary Platonists do not necessarily accept all doctrines of Plato. Platonism had a profound effect on Western thought. In its most basic fundamentals, 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.
CiceroMarcus Tullius Cicero (ˈsɪsəroʊ ; ˈmaːrkʊs ˈtʊlli.ʊs ˈkɪkɛroː; 3 January 106 BC – 7 December 43 BC) was a Roman statesman, lawyer, scholar, philosopher, writer and Academic skeptic, who tried to uphold optimate principles during the political crises that led to the establishment of the Roman Empire. His extensive writings include treatises on rhetoric, philosophy and politics. He is considered one of Rome's greatest orators and prose stylists and the innovator of what became known as "Ciceronian rhetoric".
