Diodorus Cronus
Diodorus Cronus ( el, Διόδωρος Κρόνος; died c. 284 BC) was a Greek philosopher and dialectician connected to the Megarian school. He was most notable for logic innovations, including his master argument formulated in response to Aristotle's discussion of future contingents. Life Diodorus was the son of Ameinias of Iasus in Caria. He lived in the court of Alexandria in the reign of Ptolemy I Soter, who is said to have given him the surname of Cronus ("old fogey") on account of his inability to solve at once some dialectic problem proposed by Stilpo, when the two philosophers were dining with the king. Diodorus is said to have taken that disgrace so much to heart that after his return from the meal, and writing a treatise on the problem, he died in despair. However, according to Strabo, Diodorus himself adopted the surname of Cronus from his teacher, Apollonius Cronus. Diodorus is thought to have died around 284 BC; his date of birth is unknown. It was once thought tha ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic period and the colonization of the Mediterranean Basin. This was followed by the age of Classical G ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Stoicism
Stoicism is a school of Hellenistic philosophy founded by Zeno of Citium in Athens in the early 3rd century Common Era, BCE. It is a philosophy of personal virtue ethics informed by its system of logic and its views on the natural world, asserting that the practice of virtue is both necessary and sufficient to achieve Eudaimonia, (happiness, ): one flourishes by living an Ethics, ethical life. The Stoics identified the path to with a life spent practicing the cardinal virtues and living in accordance with nature. The Stoics are especially known for teaching that "virtue is the only good" for human beings, and that external things, such as health, wealth, and pleasure, are not good or called in themselves (''adiaphora'') but have value as "material for virtue to act upon". Alongside Aristotelian ethics, the Stoic tradition forms one of the major founding approaches to virtue ethics. The Stoics also held that certain destructive emotions resulted from errors of judgment, and th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Chrysippus
Chrysippus of Soli (; grc-gre, Χρύσιππος ὁ Σολεύς, ; ) 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. Chrysippus excelled in logic, the theory of knowledge, ethics, and physics. He created an original system of propositional logic in order to better understand the workings of the universe and role of humanity within it. He adhered to a deterministic view of fate, but nevertheless sought a role for personal freedom in thought and action. Ethics, he thought, depended on understanding the nature of the universe, and he taught a therapy of extirpating the unrul ...

Antipater Of Tarsus
Antipater of Tarsus ( el, Ἀντίπατρος ὁ Ταρσεύς; died 130/129 BC) was a Stoic philosopher. He was the pupil and successor of Diogenes of Babylon as leader of the Stoic school, and was the teacher of Panaetius. He wrote works on the gods and on divination, and in ethics he took a higher moral ground than that of his teacher Diogenes. Life Very little is known about Antipater's life, except that he was the disciple and successor of Diogenes of Babylon as leader of the Stoic school in Athens, and he was the teacher of Panaetius. The few extant accounts of his philosophical opinions would not be sufficient grounds for any great reputation, if it were not for the testimony of ancient authors to his merit. Plutarch speaks of him with Zeno, Cleanthes, and Chrysippus, as one of the principal Stoic philosophers, and Cicero mentions him as remarkable for acuteness. He seems to have taken the lead during his lifetime in the disputes constantly recurring between his own scho ...

Cleanthes
Cleanthes (; grc-gre, Κλεάνθης; c. 330 BC – c. 230 BC), of Assos, was a Greek Stoic philosopher and boxer who was the successor to Zeno of Citium as the second head (''scholarch'') of the Stoic school in Athens. Originally a boxer, he came to Athens where he took up philosophy, listening to Zeno's lectures. He supported himself by working as a water-carrier at night. After the death of Zeno, c. 262 BC, he became the head of the school, a post he held for the next 32 years. Cleanthes successfully preserved and developed Zeno's doctrines. He originated new ideas in Stoic physics, and developed Stoicism in accordance with the principles of materialism and pantheism. Among the fragments of Cleanthes' writings which have come down to us, the largest is a ''Hymn to Zeus''. His pupil was Chrysippus who became one of the most important Stoic thinkers. Life Cleanthes was born in Assos in the Troad, about 330 BC. According to Diogenes Laërtius, he was the son of Phanias, and ear ...

Panthoides
Panthoides ( el, Πανθοίδης; fl. c. 275 BC) was a dialectician and philosopher of the Megarian school. He concerned himself with "the logical part of philosophy", and at some point taught the Peripatetic philosopher Lyco of Troas. He wrote a book called ''On Ambiguities'', against which the Stoic philosopher Chrysippus wrote a treatise. He disagreed with Diodorus Cronus concerning his ''Master Argument'', arguing that something is possible which can never be true, and that the impossible can never be the consequence of the possible, and that therefore not everything that has happened is necessarily true Logical truth is one of the most fundamental concepts in logic. Broadly speaking, a logical truth is a statement which is true regardless of the truth or falsity of its constituent propositions. In other words, a logical truth is a statement whic .... Diodorus' view was that everything that has happened must be true, and that therefore nothing is possible which can never b ...

Epictetus
Epictetus (; grc-gre, Ἐπίκτητος, ''Epíktētos''; 50 135 AD) was a Greek Stoic philosopher. He was born into slavery at Hierapolis, Phrygia (present-day Pamukkale, in western Turkey) and lived in Rome until his banishment, when he went to Nicopolis in northwestern Greece for the rest of his life. His teachings were written down and published by his pupil Arrian in his '' Discourses'' and ''Enchiridion''. Epictetus taught that philosophy is a way of life and not simply a theoretical discipline. To Epictetus, all external events are beyond our control; we should accept whatever happens calmly and dispassionately. However, individuals are responsible for their own actions, which they can examine and control through rigorous self-discipline. Life Epictetus was born around AD 50, presumably at Hierapolis, Phrygia. The name his parents gave him is unknown; the word ''epíktētos'' (ἐπίκτητος) in Greek simply means "gained" or "acquired"; the Greek phil ...

Master Argument
:''See Diodorus Cronus § Master argument for the classical master argument related to the problem of future contingents.'' The master argument is George Berkeley's argument that mind-independent objects do not exist because it is impossible to conceive of them. The argument is against the intuitions that many have and has been widely challenged. The term "Berkeley's master argument" was introduced by Andre Gallois in 1974. His term has firmly become currency of contemporary Berkeley scholarship. Overview In order to determine whether it is possible for a tree to exist outside of the mind, we need to be able to think of an unconceived tree. But as soon as we try to think about this tree, we have conceived it. So we have failed and there is no good reason to believe that trees exist outside of the mind. Criticisms The master argument has been seen by several prominent philosophers as having a crucial mistake; see criticisms of idealism. Bertrand Russell Bertrand Arthur W ...

George Berkeley
George Berkeley (; 12 March 168514 January 1753) – known as Bishop Berkeley (Bishop of Cloyne of the Anglican Church of Ireland) – was an Anglo-Irish philosopher whose primary achievement was the advancement of a theory he called "immaterialism" (later referred to as " subjective idealism" by others). This theory denies the existence of material substance and instead contends that familiar objects like tables and chairs are ideas perceived by the mind and, as a result, cannot exist without being perceived. Berkeley is also known for his critique of abstraction, an important premise in his argument for immaterialism. In 1709, Berkeley published his first major work, '' An Essay Towards a New Theory of Vision'', in which he discussed the limitations of human vision and advanced the theory that the proper objects of sight are not material objects, but light and colour. This foreshadowed his chief philosophical work, ''A Treatise Concerning the Principles of Human Knowledg ...

Alexander of Aphrodisias ( grc-gre, Ἀλέξανδρος ὁ Ἀφροδισιεύς, translit=Alexandros ho Aphrodisieus; AD) was a Peripatetic school, Peripatetic philosopher and the most celebrated of the Ancient Greek Commentaries on Aristotle, commentators on the writings of Aristotle. He was a native of Aphrodisias in Caria, and lived and taught in Athens at the beginning of the 3rd century, where he held a position as head of the Peripatetic school.

George Grote
George Grote (; 17 November 1794 – 18 June 1871) was an English political radical and classical historian. He is now best known for his major work, the voluminous ''History of Greece''. Early life George Grote was born at Clay Hill near Beckenham in Kent. His grandfather, Andreas, originally a Bremen merchant, was one of the founders (on 1 January 1766) of the banking-house of Grote, Prescott & Company in Threadneedle Street, London (the name of Grote did not disappear from the firm until 1879). His father, another George, married (1793) Selina, daughter of Henry Peckwell (1747–1787), minister of Selina, Countess of Huntingdon's chapel in Westminster, and his wife Bella Blosset (descended from a Huguenot officer Salomon Blosset de Loche who left the Dauphiné on the revocation of the Edict of Nantes), and had one daughter and ten sons, of whom George was the eldest. Arthur Grote was a brother. ( John Russell RA painted portraits of Henry Peckwell and Bella Blosset.) Ed ...

Contingency (philosophy)
In philosophy and logic, contingency is the status of propositions that are neither true under every possible valuation (i.e. tautologies) nor false under every possible valuation (i.e. contradictions). A contingent proposition is neither necessarily true nor necessarily false. Overview Propositions that are contingent may be so because they contain logical connectives which, along with the truth value of any of its atomic parts, determine the truth value of the proposition. This is to say that the truth value of the proposition is ''contingent'' upon the truth values of the sentences which comprise it. Contingent propositions depend on the facts, whereas analytic propositions are true without regard to any facts about which they speak. Along with contingent propositions, there are at least three other classes of propositions, some of which overlap: * '' Tautological'' propositions, which ''must'' be true, no matter what the circumstances are or could be (example: "It is the cas ...
