61. THEAETETUS with Socrates enquiring of the visiting geometer, theodorus of cyrene, He bids Theodorus and Theaetetus farewell, and entreats them to join him http://caae.phil.cmu.edu/Cavalier/80250/Plato/Theatetus/Theat.html

THE PATH OF KNOWLEDGE: THE THEAETETUS The Theaetetus can be considered a Socratic dialogue, since in it we do not arrive at any definitive answers to the questions which are posed. Its central concern is the problem of knowledge, yet its main conclusions all serve to show us what knowledge is not. Be this as it may, the Theaeteus rightfully belongs to the later set of dialogues since it prepares the way for the truly Platonic analyses of knowledge which are found in the Sophist. The Theaeteus, by clearing away many false opinions, allows Plato to introduce his own full-blown theory, a theory which connects the problem of knowledge with the realm of the Forms. Because of this interconnection between the two dialogues, and because the analyses of the Sophist presuppose the negative critiques of the Theaeteus, we shall begin our path of knowledge with the Socratic problem. The dialogue opens with a brief prologue which serves to date the time of the supposed conversation. An introduction then guides the reader into the setting for the discussions which were to have taken place between an aging Socrates and a youthful Theaetetus. It ishere that the dialogue is given its direction through the posing of its central question: "What is the nature of knowledge?" Theaetetus makes three general attempts to answer this question, and his responses form the major divisions of the work. The first attempt tries to equate knowledge with sense perception; the second speaks of knowledge as true judgement (but how do we know that a judgement is true?); the third response augments the second by saying that knowledge is true Judgement accompanied by an explanation. Yet Socrates is able to show Theaetetus that each attempt to arrive at an absolute answer to the problem of knowledge is fatally flawed. In the end, we are left with an awareness of our ignorance concerning the nature of knowledge (and the way is prepared for the more thoroughgolng analyses of the Sophist).

The Peripatetics called God the locus rerum to/poj pa/ntwn , the "locality and the area of all things;" that is, the being in whom all else was contained. [This prayer of Arnobius is surely worthy of admiration.] Diagoras of Melos and Theodorus of Cyrene, called the Atheists. The former flourished about B.C. 430, the latter about B.C. 310. See Cic., Nat. Deor. , i. 2. [Note the universal faith, cap. 34, infra Protagoras of Abdera, b. B.C. 480, d. 411. Democritus of Abdera, b. B.C. 460, and Epicurus, b. B.C. 342, d. 270.

So the ms.; for which Meursius would read, nobis vobisque, communis esset (for cessat )- "is to us and to you, the anger of the gods would be shared in common." So Ursinus, followed by most edd., for the reading of the ms. Fenta Fatua , cf. v. 18. A later writer has corrected the ms. Fanda , which, Rigaltius says, an old gloss renders "mother." So restored by Salmasius for Dioscuri , and understood by him as meaning Dea Syria, i.e. Venus, because it is said that a large egg having been found by the fish in the Euphrates, was pushed up by them to the dry land, when a dove came down, and sat upon it until the goddess came forth. Such was the form of the legend according to Nigidius; but Eratosthenes spoke of both Venus and Cupid as being produced in this manner. The Syrian deities were therefore Venus, Cupid, and perhaps Adonis. It should be remembered, however, that the Syrians paid reverence to pigeons and fish as gods. (Xen.

ANF04. Fathers of the Third Century: Tertullian, Part Fourth; Minucius Felix; Commodian; Origen, Parts First and Second Minicius Felix Minucius Felix Introductory Note to Minucius Felix. a.d. 210.] Though Tertullian is the founder of Latin Christianity, his contemporary Minucius Felix gives to Christian thought its earliest clothing in Latinity. The harshness and provincialism, with the Graecisms, if not the mere Tertullianism , of Tertullian, deprive him of high claims to be classed among Latin writers, as such; but in Minucius we find, at the very fountain-head of Christian Latinity, a disciple of Cicero and a precursor of Lactantius in the graces of style. The question of his originality is earnestly debated among moderns, as it was in some degree with the ancients. It turns upon the doubt as to his place with respect to Tertullian, whose Apology he seems to quote, or rather to abridge. But to me it seems evident that his argument reflects so strikingly that of Tertullian’s Testimony of the Soul , coincident though it be with portions of the Apology, that we must make the date of the Testimony the pivot of our inquiry concerning Minucius. Now, Tertullian’s

web hosting domain names photo sharing CHRONOLOGY OF THE SQUAREGATE (MATHEMATICS BEHIND "CANDY MISER'S PUZZLE") Mathematicians and students today extensively apply the right triangle in geometry and trigonometry using the "Pythagorean Formula" to relate lengths of the triangle's SIDES ( a, b ) and DIAGONAL ( c ): a + b = c . However, Pythagoras did not discover this formula, but apparently learned it in his travels through Egypt and Mesopotamia. Nevertheless, Knowledge of Egyptian mathematics derives from two artifacts, The Rhynd Papyrus (named for its donor to The British Museum) and The Moscow Papyrus (now in Museum of Fine Arts, Moscow, Russia). Both apparently derive from a period between 2000 B.C. and 1580 B.C. They describe ability to solve linear (first degree) equations in one unknown , but no evidence of solving second degree equations or formulas such as "The Pythagorean". The Egyptians deal with fractions by adding unit fractions , such as 1/2, 1/3, 1/4, 1/5, etc. (You use "Egyptian fractions" nearly every day in "making change in commercial transactions". Thus, a penny = $1/100; a nickel = $1/20; a dime = $1/10; a quarter = $1/4; a fifty-cent piece = $1/2.) Later we'll see how the "Egyptian fraction" format extends to the best test of irrationality of numberness The "Pythagorean" formula was discovered circa 2000 B.C. in Babylonia or Egypt or both. We know about its Babylonian origin from approximately half of a million clay Babylonian tablets engraved in their written

The focus is on what new subjects arise from analyzing philosophical criticisms and defenses - even iterated. The value of a creative process of iteration is without question in either the history of philosophy or of mathematics. But the pursuit of these subjects without the foundational "philosophical approach" of attempting to establish the Truth about the particular matter is of less value. That is, it is essential to the iterative process that someone be trying to establish a truth which would come under the heading of Philosophy. > Just giving it their best shot, hoping that their views and criticisms will stand the test of time.

Lack of popular consensus on a work does not mean it is of no value. But we shall agree to differ. Indeed, many classical texts in philosophy have lots of "permanent value" in this ENTIRELY DIFFERENT sense , entirely different than *permanent-value-as-knowledge* > As for Godel, yes I am perfectly aware of his work and its place in the literature, but the impression I get is there is nowadays a distinct movement against attributing any great philosophical significance to it. After all there are still formalists and Maddy/Yablo-esque "semi-formalists".

71. Pythagoras He may have stumbled on the fact that the square root of two is a surd, but weknow that it was left for Plato s friends, theodorus of cyrene and Theaetetus http://www.omhros.gr/Kat/History/Greek/Tc/Pythagoras.htm

Pythagoras b. c. 580 BC,, Samos, Ionia d. c. 500,, Metapontum, Lucania Greek philosopher, mathematician, and founder of the Pythagorean brotherhood that, although religious in nature, formulated principles that influenced the thought of Plato and Aristotle and contributed to the development of mathematics and Western rational philosophy (see Pythagoreanism Pythagoras migrated to southern Italy about 532 BC, apparently to escape Samos' tyrannical rule, and established his ethico-political academy at Croton (now Crotona). It is difficult to distinguish Pythagoras' teachings from those of his disciples. None of his writings has survived, and Pythagoreans invariably supported their doctrines by indiscriminately citing their master's authority. Pythagoras, however, is generally credited with the theory of the functional significance of numbers in the objective world and in music. Other discoveries often attributed to him (e.g., the incommensurability of the side and diagonal of a square, and the Pythagorean theorem for right triangles) were probably developed only later by the Pythagorean school. More probably the bulk of the intellectual tradition originating with Pythagoras himself belongs to mystical wisdom rather than to scientific scholarship. (C) 2000 Britannica.com Inc.

72. Ancient Scepticism And Ancient Religion theodorus of cyrene is often invoked, on hazier grounds. Critias is cited for adebunking speech in a play. Cicero, at De Natura Deorum 2, cites Diagoras, http://www.u.arizona.edu/~jannas/forth/Assos1.htm

Ancient scepticism and ancient religion Julia Annas Religion figures in the ancient Pyrrhonist claim that scepticism does not lead to conflict with the living of ordinary life. In Diogenes Laertius’ Life of Pyrrho we find, among the stories illustrating the idea that Pyrrho lived, consistently with his philosophy, a normal life, the claim that he became a high priest in his home town of Elis. (Also, though I shall not be talking about the Academics, it is interesting that Cicero in his dialogue The Nature of the Gods puts forward, to attack arguments for the existence of the gods, Aurelius Cotta, who is a prominent priest and who says that ‘no words from any person, whether learned or unlearned, will ever budge me from the views which I inherited from our ancestors concerning the worship of the immortal gods.’ ) Sextus twice gives arguments for and against the existence of the gods, at M IX 11-194 and PH III 2-12, and each time claims that the sceptic, who is led to suspension of judgement on this, will lead an ordinary religious life At M IX 49 he says that perhaps the sceptic will be safer than other philosophers, since ‘in conformity with his ancestral customs and the laws he declares that the Gods exist, and performs everything which contributes to their worship and veneration, but, so far as concerns philosophic investigation, declines to commit himself rashly.’

73. Atheism_theory The few, however, of whom we can be sure, are people like Diagoras of Melos andtheodorus of cyrene (fifth and fourth centuries BC.). http://www.catholic-church.org/church-unity/ateo_t_e.htm

ATHEISM: A PHILOSOPHICAL EXAMINATION THEORETICAL ATHEISM Historical trends  In examining the phenomenon of theoretical atheism the various philosophical trends or dynamics which were at play through history will be examined first, and then some of the individual representatives of various atheistic theories, systems and doctrines.  The first thing to be noticed in making a brief survey of history is that atheism is primarily a western European phenomenon. In examining it, one can notice that it has evolved and developed into various forms and systems. It has reached a certain maturity, it has been explained and understood very philosophically.  In examining the historical trends, an exploration will be made into the origins, the roots and the development process towards theoretical atheism. At the end of this exploration, it is hoped, that one will be able to understand at least in part of the foundation upon which philosophical atheism stands. 2.1.1. Islamic philosophers Nominalism  C hristendom (the Roman Empire) had suffered the Barbarian invasions of the fifth and sixth centuries. It had been basically devastated. Its universities, its culture, its intelligentsia greatly suffered. Under the influence of Charlemagne the monastic schools were founded and developed, evolving into the great universities of the eleventh and subsequent centuries. Within the university ambient, the philosophies of various Arab (Muslim) and Jewish philosophers were introduced. These philosophers introduced the thought of Aristotle giving it a neo-platonic interpretation.

home index ancient Greece Cyrene and the Cyrenaica Cyrene: Greek city in Libya, modern Shahhat. Cyrenaica: the country surrounding Cyrene. Cyrene was founded in c.630 BCE as a colony of the Greek island town Thera, which had become too crowded. The first colonists settled at an island called Platea in front of the Libyan coast (modern Bomba). Later, they occupied a coastal strip called Aziris, and finally, after concluding a treaty with the native Libyans, they founded the town Cyrene. The leader of the settlers was Aristoteles, but he was called Battus. (Which means 'stammerer' in Greek, but is probably a Libyan royal title.) In the following centuries, Battus' descendants ruled Cyrene. Aristoteles Battus I c.631-c.599 Arcesilas I c.599-c.583 Battus II the Blessed c.583-c.560 Arcesilas II the Tough c.560-c.550 Battus III the Lame c.550-c.530 Arcesilas III c.530-c.514 Battus IV the Fair c.514-c.470 Arcesilas IV c.470-c.440 Although Cyrene was founded after a treaty with the natives, the relations between the Greeks and Libyans were often strained, and the settlers sometimes felt threatened. As a consequence, during the reign of Battus II, new settlers were invited from the homeland. They received Libyan land, which caused great resentment. The Libyans requested the Egyptian king Apries to assist them in a war against the Greeks, but the pharaoh was defeated (570).

var baseDir = '../'; @import url("../style/ie.css"); EGS Home MA in Communication PhD in Communication Admin ... EGS Online Plato Links Biography Plato (circa 428-c. 347 BC) Plato was born around the year 428 BCE in Athens. His father died while Plato was young, and his mother remarried to Pyrilampes, in whose house Plato would grow up. Plato's birth name was Aristocles, and he gained the nickname Platon, meaning broad, because of his broad build. His family had a history in politics, and Plato was destined to a life in keeping with this history. He studied at a gymnasium owned by Dionysios, and at the palaistra of Ariston of Argos. When he was young he studied music and poetry. According to Aristotle, Plato developed the foundations of his metaphysics and epistemology by studying the doctrines of Cratylus, and the work of Pythagoras and Parmenides. When Plato met Socrates, however, he had met his definitive teacher. As Socrates' disciple, Plato adopted his philosophy and style of debate, and directed his studies toward the question of virtue and the formation of a noble character. Plato was in military service from 409 BC to 404 BC. When the Peloponnesian War ended in 404 BC he joined the Athenian oligarchy of the Thirty Tyrants, one of whose leaders was his uncle Charmides. The violence of this group quickly prompted Plato to leave it. In 403 BC, when democracy was restored in Athens, he had hopes of pursuing his original goal of a political career. Socrates' execution in 399 BC had a profound effect on Plato, and was perhaps the final event that would convince him to leave Athenian politics forever.
