Arcesilaus
Arcesilaus (; grc-gre, Ἀρκεσίλαος; 316/5–241/0 BC) was a Greek Hellenistic philosopher. He was the founder of Academic Skepticism and what is variously called the Second or Middle or New Academy – the phase of the Platonic Academy in which it embraced philosophical skepticism. Arcesilaus succeeded Crates of Athens as the sixth scholarch of the Academy around 264 BC. He did not preserve his thoughts in writing, so his opinions can only be gleaned second-hand from what is preserved by later writers. In Athens Arcesilaus interacted with the Pyrrhonist philosopher, Timon of Phlius, whose philosophy appears to have influenced Arcesilaus to become the first Academic to adopt a position of philosophical skepticism, that is, he doubted the ability of the senses to discover truth about the world, although he may have continued to believe in the existence of truth itself. This brought in the skeptical phase of the Academy. His chief opponent was his contemporary, Z ...

Academic Skepticism
Academic skepticism refers to the skeptical period of ancient Platonism dating from around 266 BCE, when Arcesilaus became scholarch of the Platonic Academy, 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. Overview Greek p ...

Platonic Academy
The Academy ( Ancient Greek: Ἀκαδημία) was founded by Plato in c. 387 BC in Athens. Aristotle studied there for twenty years (367–347 BC) 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. Site The ''Akademia'' was a school outside the city walls of ancient Athens. It was located in or beside a grove of olive trees dedicated to the goddess Athena, which was on the site even before Cimon enclosed the precincts with a wall. The archaic name for the site was ''Ἑκαδήμεια'' (''Hekademia''), which by classical times evolved into Ἀκαδημία (''Akademia''), which was explained, at least as early as the beginning of the 6th century BC, by linking it to "Akademos", a legendary Athenian hero. The site of the Academy was sacred to A ...

Western Philosophy
Western philosophy encompasses the philosophy, philosophical thought and work of the Western world. Historically, the term refers to the philosophical thinking of Western culture, beginning with the ancient Greek philosophy of the Pre-Socratic philosophy, pre-Socratics. The word ''philosophy'' itself originated from the Ancient Greek (φιλοσοφία), literally, "the love of wisdom" grc, φιλεῖν , "to love" and σοφία ''Sophia (wisdom), sophía'', "wisdom"). History Ancient The scope of ancient Western philosophy included the problems of philosophy as they are understood today; but it also included many other disciplines, such as pure mathematics and natural sciences such as physics, astronomy, and biology (Aristotle, for example, wrote on all of these topics). Pre-Socratics The pre-Socratic philosophers were interested in cosmology; the nature and origin of the universe, while rejecting Greek mythology, mythical answers to such questions. They were spe ...

Pyrrhonism
Pyrrhonism is a school of philosophical skepticism founded by Pyrrho in the fourth century BCE. It is best known through the surviving works of Sextus Empiricus, writing in the late second century or early third century CE. History Pyrrho of Elis (c. 360 – c. 270 BCE) and his teacher Anaxarchus, both Democritean philosophers, traveled to India with Alexander the Great's army where Pyrrho was said to have studied with the magi and the gymnosophists, and where he was influenced by Buddhist teachings, most particularly the three marks of existence. After returning to Greece, Pyrrho started a new line of philosophy now known as "Pyrrhonism." His teachings were recorded by his student Timon of Phlius, most of whose works have been lost. Pyrrhonism as a school was either revitalized or re-founded by Aenesidemus in the first century BCE. This phase of Pyrrhonism, starting with Aenesidemus and going through the last known Pyrrhonist of antiquity, Saturninus, is sometimes referred ...

Carneades
Carneades (; el, Καρνεάδης, ''Karneadēs'', "of Carnea"; 214/3–129/8 BC) was a Greek philosopher and perhaps the most prominent head of the Skeptical Academy in ancient Greece. He was born in Cyrene. By the year 159 BC, he had begun to attack many previous dogmatic doctrines, especially Stoicism and even the Epicureans whom previous skeptics had spared . As scholarch (leader) of the Academy, he was one of three philosophers sent to Rome in 155 BC where his lectures on the uncertainty of justice caused consternation among leading politicians. He left no writings. Many of his opinions are known only via his successor Clitomachus. He seems to have doubted the ability not just of the senses but of reason too in acquiring truth. His skepticism was, however, moderated by the belief that we can, nevertheless, ascertain probabilities (not in the sense of statistical probability, but in the sense of persuasiveness) of truth, to enable us to act. Biography Carneade ...

Pyrrho
Pyrrho of Elis (; grc, Πύρρων ὁ Ἠλεῖος, Pyrrhо̄n ho Ēleios; ), born in Elis, Greece, was a Greek philosopher of Classical antiquity, credited as being the first Greek skeptic philosopher and founder of Pyrrhonism. Life Pyrrho of Elis is estimated to have lived from around 365/360 until 275/270 BCE. Pyrrho was from Elis, on the Ionian Sea. He was likely a member of the Klytidiai, a clan of seers in Elis who interpreted the oracles of the Temple of Zeus at Olympia where Pyrrho served as a high priest. The Klytidiai were descendants of Klytios, who was the son of Alcmaeon and the grandson of Amphiaraus. In the ''Python'', Pyrrho's student Timon of Phlius describes first meeting Pyrrho on the grounds of an Amphiareion, i.e., a temple of Amphiaraus, while they were both on a pilgrimage to Delphi. Diogenes Laërtius, quoting from Apollodorus of Athens, says that Pyrrho was at first a painter, and that pictures by him were exhibited in the gymnasium a ...

Lacydes Of Cyrene
Lacydes of Cyrene ( grc-gre, Λακύδης ὁ Κυρηναῖος), Academic Skeptic philosopher, was head of the Platonic Academy at Athens in succession to Arcesilaus from 241 BC. He was forced to resign c. 215 BC due to ill-health, and he died c. 205 BC. Nothing survives of his works. Life He was born in Cyrene, the son of Alexander. In his youth he was poor, but remarkable for his industry, as well as for his affable and engaging manners. He moved to Athens, and attached himself to the Middle Academy, according to a silly story quoted by Eusebius Eusebius, '' Praeparatio Evangelica'' xiv. 7. from Numenius, because the ease with which his servants robbed him without being detected, convinced him that no reliance could be placed on the evidence of the senses. He was a disciple of Arcesilaus, and succeeded him as head ( scholarch) of the school in 241 BC, over which he presided for 26 years. The place where his instructions were delivered was a garden, named the ''Lacydeum ...

Socrates
Socrates (; ; –399 BC) was a Greek philosopher from Athens who is credited as the founder of Western philosophy and among the first moral philosophers of the ethical tradition of thought. 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. Contradictory accounts of Socrates make a reconstruction of his philosophy nearly impossible, a situation known as the Socratic problem. Socrates was a polarizing figure in Athenian society. In 399 BC, he was accused of impiety and corrupting the youth. After a trial that lasted a day, he was sentenced to death. He spent his last day in prison, refusing offers to help him escape. Plato's dialogues are among the most ...

Hellenistic Philosophy
Hellenistic philosophy is a time-frame for Western philosophy and Ancient Greek philosophy corresponding to the Hellenistic period. It is purely external and encompasses disparate intellectual content. There is no single philosophical school or current that is either representative or dominating for the period. Background The classical period in Ancient Greek philosophy had begun with Socrates (c. 470–399 BC), whose student Plato had taught Aristotle, who, in turn, had tutored Alexander. The period began with the death of Alexander in 323 BC (followed by the death of Aristotle the next year in 322 BC). While the classical thinkers were mostly based in Athens, at end of the Hellenistic period philosophers relocated at Rome or Alexandria. The shift followed Rome's military victories from the middle of the second century. Sulla's capture of Athens in 87 led to destructions and the shipping of Aristotle's manuscripts to Rome. The end of the Hellenistic period does not correspo ...

Pitane (Aeolis)
Pitane ( grc, Πιτάνη), near Çandarlı, Turkey, was an ancient Greek town of the ancient region of Aeolis, in Asia Minor. It was situated near the mouth of the river Evenus on the bay of Elaea. It was one of the eleven ancient Aeolian settlements, and possessed considerable commercial advantages in having two harbours. It was the birthplace of the academic philosopher Arcesilaus, and in the reign of Titus it suffered severely from an earthquake. The town is still mentioned by Hierocles. Pliny the Elder mentions in its vicinity a river Canaius, which is not noticed by any other writer; but it may possibly be the river Pitanes, spoken of by Ptolemy, and which seems to derive its name from the town of Pitane. Its site is near modern Çandarlı, Asiatic Turkey. History Excavations in the necropolis of Pitane revealed ceramic finds from the Mycenaean, protogeometric, geometric, orientalizing and the Archaic Greek periods. Pitane is believed to be the northernmost point ...

Philosophical Skepticism
Philosophical 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. This distinction is modeled after the differences between the Academic skeptics and the Pyrrhonian skeptics in ancient Greek philosophy. In the latter sense, skepticism is understood as a way of life that helps the practitioner achieve inner peace. Some types of philosophical skepticism reject all forms of knowledge while others limit this rejection to certain fields, for example, to knowledge about moral doctrines or about the external world. Some theorists c ...

Epistemology
Epistemology (; ), or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the ...
