Extractions: Xenocrates of Chalcedon was a student of Plato who entered the Academy in Athens in about 376 BC. In about 367 BC Xenocrates accompanied Plato on his journey to Syracuse following the death of Dionysius I . Xenocrates left Athens with Aristotle after Plato 's death in 347 BC when they were both invited to Assos. Xenocrates remained for around five years in Assos. Plato 's nephew Speusippus had become head of the Academy on Plato 's death, but in 340 BC he sent for Xenocrates to return to Athens to prepare to become his successor. Despite Xenocrates having been chosen to head the Academy by Speusippus, an election took place to find a successor to Speusippus after his death. It was a close battle between Xenocrates, Menedemus of Pyrrha and Heraclides Ponticus but Xenocrates triumphed by just a few votes. Although Xenocrates had been many years in Athens he had refused to become a citizen of that state since he did not approve of its close relations with Macedonia. In this respect he contrasted strongly with his predecessor Speusippus who had strongly supported the political ties between Athens and Macedonia. It is clear that the Academy at this time was far from what many picture it as, namely an institution where scholars sat thinking, isolated from the world around them. On the contrary, the

Extractions: Aristotle was not primarily a mathematician but made important contributions by systematising deductive logic. He wrote on physical subjects: some parts of his Analytica posteriora show an unusual grasp of the mathematical method. Primarily, however, he is important in the development of all knowledge for, as the authors of [2] write:- Aristotle, more than any other thinker, determined the orientation and the content of Western intellectual history. He was the author of a philosophical and scientific system that through the centuries became the support and vehicle for both medieval Christian and Islamic scholastic thought: until the end of the 17 th century, Western culture was Aristotelian. And, even after the intellectual revolutions of centuries to follow, Aristotelian concepts and ideas remained embedded in Western thinking. Aristotle was born in Stagirus, or Stagira, or Stageirus, on the Chalcidic peninsula of northern Greece. His father was Nicomachus, a medical doctor, while his mother was named Phaestis. Nicomachus was certainly living in Chalcidice when Aristotle was born and he had probably been born in that region. Aristotle's mother, Phaestis, came from Chalcis in Euboea and her family owned property there.

Extractions: Previous (Alphabetically) Next Welcome page Xenocrates was a student of Plato who left Athens with Aristotle after Plato 's death in 347 BC, returning in 339 BC when he was elected as head of the Academy. He remained at the Academy in Athens for the rest of his life. Xenocrates wrote on philosophy and mathematics. All his books are lost and it would appear that there only ever existed a single copy of each in his own hand. Xenocrates believed that matter is composed of indivisible units, so he may be regarded as an early believer in the atomic theory. He agreed with Pythagoras regarding the importance of numbers in philosophy and attributed to Pythagoras an atomic view of acoustics where sound, perceived as a single entity, consists of discrete sounds. Xenocrates believed in human beings having threefold existence, mind, body and soul. It is not clear whether he was the instigator of this belief. He also believed that people die twice, once on Earth, then for a second time on the Moon when the mind separates from the soul and travels to the Sun.

Extractions: XENOCRATES XENOCRATES of Chalcedon attached himself to Plato, whom he accompanied in his journey to Dionysus, in Sicily. The greater part of his life was spent in the Academy, over which he presided after the death of Plato's pupil, Speusippus, for twenty-five yearsB.C. 339-314. He was noted for gravity of demeanour, for temperance, veracity, and integrity, and is frequently praised and cited by Cicero . When sent as a member of the Athenian embassy to Philip of Macedon, he stood alone in inflexible refusal to receive bribe or favour; and he maintained the same character in his embassy to Antipator. He was a voluminous writer, but nothing except the catalogue of his works has come down to us. He died at the age of 82. His position in philosophy is that of an immediate successor to Plato, who developed the Platonic system, especially in its tendency to Monotheism as the basis of a purer and stronger moral life.

Extractions: PLATO (428-348 B.C.) P lato of Athens (428-348), also combined the genius of Socrates with all the principles established by earlier philosophers, in so far as they had been legitimate, and developed the whole of this material into the unity of a comprehensive system. The groundwork of Plato's scheme, though nowhere expressly stated by him, is the threefold division of philosophy into dialectic ethics , and physics ; its central point is the theory of forms or ideas . This theory is a combination of the Eleatic doctrine of the One with Heraclitus's theory of a perpetual flux and with the Socratic method of concepts . The multitude of objects of sense, being involved in perpetual change, are thereby deprived of all genuine existence. The only true being in them is founded upon the ideas, the eternal unchangeable (independent of all that is accidental, and therefore perfect) types, of which the particular objects of sense are imperfect copies . The quantity of the forms is defined by the number of universal concepts which can be derived from the particular objects of sense. The highest idea is that of the Good , which is the ultimate basis of the rest, and the first cause of being and knowledge. Apprehensions derived from the impression of sense can never give us the knowledge of true being i.e. of the forms. It can only be obtained by the

Extractions: "In pure mathematics [Hipparchus] is said to have considered a problem in permutations and combinations, the problem of finding the number of different possible combinations of 10 axioms or assumptions, which he made to be 103049 (v.l. 101049) or 310952 according as the axioms were affirmed or denied. It seems impossible to make anything of these figures." Heath , History of Greek Mathematics According to [ST97] Plutarch (50-120 AD) said "Chrysippus says that the number of compound propositions that can be made from only ten simple propositions exceeds a million. (Hipparchus, to be sure, refuted this by showing that on the affirmative side there are 103049 compound statements, and on the negative side 310952.)"
