Theaetetus BC BC Most of what we know of Theaetetus's life comes from the writing of Plato. It is clear that Plato held Theaetetus in the highest regard and he wrote two dialogues which had Theaetetus as the principal character. He was sent to Athens to be educated at the Academy there under Plato. He died of wounds he received in the battle between Athens and Corinth around 369 BC Theaetetus made very important contributions to mathematics, despite none of his writing having survived. Books 10 and 13 of Euclid's Elements are almost certainly a description of Theaetetus's work. This means that it was Theaetetus's work on irrational lengths which is described in the Book 10, thought by many to be the finest work of the Elements. Theaetetus was no doubt inspired by the work of Theodorus to work on incommensurables, and that he made major contributions to the theory. Given two magnitudes a and b, then the medial is ab, the binomial is a+b, and the apotome is a-b. It was also Theaetetus who "assigned the medial line to geometry, the binomial to arithmetic and the apotome to harmony". He was the first to generalize Theodorus's proof that 3, 5, ..., 17 were irrational to all non-square numbers, which he called oblong numbers. Theaetetus is also thought to be the author of the theory of proportion which appears in Eudoxus's work. Theaetetus was the first to study the octahedron and the icosahedron, the other 3 Platonic solids being studied by the Pythagoreans.

Roster As-D Return to index to rosters Augustine of Hippo Cleisthenes Athenian statesman, from the famous family of Alcmaeonids. Late in the tyranny of Hippias Cleisthenes was banished from Athens. He was said to have bribed the priestess at Delphi into guaranteeing that the oracle would advise all Spartans to overthrow the tyranny in Athens. (See Pisistratus .) Delphi, in return, got Cleisthenes' promise to help bankroll the renovation of the temple. The priestess took the bribe, the Spartans took the advice, Hippias was overthrown and Cleisthenes returned to Athens (511/10 B.C.E. to head one of two aristocratic factions. When the rival faction, headed by Isagoras, got the upperhand, the ever resourceful Cleisthenes appealed to the people and succeeded in passing a sweeping set of democratic reforms that included redefinition of the tribes of Athens (a sort of ancient gerrymandering), granting of sweeping powers to the Council of 500 ( BOULE ,) empowering of the Assembly of all citizens ( EKKLESIA ,) and instituting ostracism , the curious Athenian law by which the citizens could vote to excile for ten years, with or without cause, one of their fellow citizens.

Any of these arrangements may suggest new views to the student of Plato; none of them can lay claim to an exclusive probability in its favour. The Theaetetus is one of the narrated dialogues of Plato, and is the only one which is supposed to have been written down. In a short introductory scene, Euclides and Terpsion are described as meeting before the door of Euclides' house in Megara. This may have been a spot familiar to Plato (for Megara was within a walk of Athens), but no importance can be attached to the accidental introduction of the founder of the Megarian philosophy. The real intention of the preface is to create an interest about the person of Theaetetus, who has just been carried up from the army at Corinth in a dying state. The expectation of his death recalls the promise of his youth, and especially the famous conversation which Socrates had with him when he was quite young, a few days before his own trial and death, as we are once more reminded at the e Reviews Be the first to review this title!

Socrates: Midwife to Our Souls By W. T. S. Thackara Part I Although philosophy often conjures a picture of dry semantics and intellectual debate, it was not so for Socrates or Plato. Their common goal was to help bring forth our innately human and divine qualities in an everyday, wonderful, and inspiring quest they called philosophy . For them philosophy was what the word literally denotes. It is about love and wisdom, and, by extension, all else that is important and meaningful in life: truth, goodness, beauty, justice, virtue, friendship, and not least of all happiness. As with many of the world's great teachers, Socrates wrote little if anything; and it is principally through Plato's Dialogues that the world knows him. Other far briefer and less well-known accounts exist, such as those of Plato's contemporary, Xenophon and, some 600 years later, of Diogenes Laertius, whose biography attempted to synthesize all known Socratic lore. There is also Aristophanes' parody in The Clouds which tells us little about Socrates, except perhaps something of his early career, before the Oracle's famous utterance which so profoundly changed his life. Plato's account, on the other hand, portrays a mentor and friend by his own admission an idealized rendering, making it difficult to determine what is uniquely Socrates' teaching and what is Plato's. But the problem is not so important, for their aim was essentially the same. When Plato writes of Socrates as a midwife, he tells a story about the relationship between teacher and student, about education, and about the birth of spiritual-intellectual fire in the soul. Plato's choice of the dialogue as his principal literary vehicle serves many purposes. Besides illustrating Socrates' good-natured but persistently one-pointed method of inquiry, it provides insight into the nature and goals of the teacher-student collaboration. At a deeper level, the Dialogues themselves invite us to participate with Socrates in our own unfolding search for truth.

If society is not based on the commitment to discover and know the complex domain, and hence, to make decisions based on universal principles and a commitment to the Good, it will begin to degenerate, as Plato's Athens did. Above: Parthenon, Acropolis, Athens; Inset: Plato Plato's dialogues encompass an historical sweep of time, f rom Athens at its height in 450 B.C to its defeat in the Peloponnesian War, to the death of Socrates in 399 B.C and beyond. That more than half-century witnessed the self-destruction of Athens, as its imperial ambitions brought it into conflict with its neighboring city-states, especially Sparta, thus precipitating the Peloponnesian war in 432. A series of disasterous decisions led to Athens' ultimate defeat in 404. Against this backdrop, Plato sketched the tragedy of Athens, peopling his dialogues with the very political and military leaders, and pseudo-philosophers, who, step-by-step, led Athens to its doom.

Contact Us Your Location: Home Essays Philosophy Essays Plato's Critique of the Pre-Socratic Philosophers Plato's Critique of the Pre-Socratic Philosophers Written by Steve Giardina Tuesday, 10 February 2004 Throughout the ancient Greek civilization, there were numerous philosophers that attempted to gain knowledge of reality and man’s place in it. Specifically, before the famous philosopher, Plato, there were essentially two groups of ancient Greek philosophers: the “pre-Socratics” and the sophists. According to their doctrines, the pre-Socratics were primarily concerned with understanding the fundamental unit of reality, that which underlies all of reality and makes it be (referred to as cosmos in Greek). The sophists however were primarily concerned with the study of man’s nature as a human being (referred to as anthropos in Greek). Years later, when Plato came to prominence, he heavily criticized the philosophies of the pre-Socratics and the sophists. Specifically, in such works as Phaedo Republic , and Theaetetus , Plato came to reject the pre-Socratic account of causes that arose from their study of cosmos as well as the relativism and skepticism of the sophists that arose out of their study of anthropos. Most importantly, through his own doctrine, he came to integrate cosmos and anthropos into one complete philosophy.

93. PART II COURSES One is on the set text, and will contain questions on the theaetetus, athens and Sparta, themselves both different from each other and in their own ways http://www.classics.cam.ac.uk/undergrad_handbook/partII.html

PART II COURSES Introduction Within Classics Part II, you can choose to specialise within one discipline or you may spread yourself out more widely, or indeed very widely, across several. The basic rule is that for everyone taking Part II in one year (i.e. almost everyone), two out of your four papers should come from a single area of study (A, B, C, D, E or X). There is also a large range of papers - the O papers - offered by other faculties from which you can choose one. For details of the current O papers, see p. 102. You can also substitute for one paper a thesis of your own devising on any subject within the field of Classics. A full statement of the relevant regulations for the thesis can be found on pp. 113-115, with further advice on p. 120. All papers in the examination carry equal weight, and a thesis, if you offer one, carries the same weight as a paper. You should therefore ordinarily expect to divide your time more or less equally between your four papers, or your three papers and thesis. The Faculty advises that for each of the four this means a norm of five supervisions for which substantial pieces of written work are prepared. For some of the O papers however, a different number of supervisions is recommended; for details, you should consult your Director of Studies, or the Undergraduate Adviser. Part II offers you the opportunity to explore in depth whatever subjects you take on and to engage with them critically. Your supervisors will expect a greater range of reading both in classical texts and in the modern scholarly literature, and they will be hoping for more ambitious essay work. If you have not already penetrated the collections of the University Library, now is the time to do so. It will be important to prepare carefully for the relatively few Faculty lectures and classes provided for the options you have chosen, to be able to contribute to discussion as well as to derive maximum benefit yourself. In general, Part II gives you the chance to take responsibility for your own learning with the support of those teaching you.

THE GOLDEN AGE AND THE GOLDEN MEAN The second half of the 5th century B.C. was the Golden Age of Greece. This was the period of her most beautiful art and architecture, and some of her wisest thinkers besides. Both owed much to the popular new study of geometry. By the start of the next century, geometry itself was entering its own classic age with a series of great developments, including the Golden Mean. The times were glorious in many ways. The Persian invaders had been driven out of Hellas forever, and Pericles was rebuilding Athens into the most beautiful city in the world. At his invitation, Greek mathematicians from elsewhere flocked into the new capital. From Ionia came Anaxa- goras, nicknamed "the mind." From southern Italy and Sicily came learned Pythagoreans and the noted Zeno of Elea. And their influence was felt over all Athens. High on the hill of the Acropolis rose new marble temples and bronze and painted statues. Crowds thronged the vast new open-air theater nearby, to hear immortal tragedies and comedies by the greatest Greek playwrights. These splendid public works were completed under the direction of the sculptor Phidias and several architects, all of whom knew and used the principles of geometry and optics. "Success in art," they insisted, "is achieved by meticulous accuracy in a multitude of mathematical proportions." And their buildings had a dazzling perfection never seen before-the beauty of calculated geometric harmony.

Next Plato’s Theaetetus Plato’s Theaetetus is a dialogue between Socrates (an Athenian philosopher), Theodorus (a mathematician), and Theaetetus (a young aristocrat). The dialogue is mainly concerned with the question of what is knowledge and with the question of what is the difference between knowledge and perception. Theodorus introduces Theaetetus to Socrates, and Socrates asks Theaetetus if he is learning geometry and astronomy from Theodorus. Theaetetus replies that he is, and Socrates asks him if learning about a field of study is the same as becoming wiser about that field of study (145d). Theaetetus agrees with this proposition, and he is then asked by Socrates if wisdom is the same as knowledge (145e). Theaetetus agrees that it is, and Socrates then asks him to define the meaning of the term 'knowledge.' Theaetetus replies that geometry, astronomy, mathematics, and other disciplines are branches of knowledge, and that they constitute knowledge (146d). However, Socrates explains that this answer does not define the meaning of the term 'knowledge.' Theaetetus answers that knowledge is the same as perception (151e). However, Socrates replies that different people may have different perceptions of the same object, and that their perceptions of an object may be based on the appearance of that object. The appearance of an object may change without any change in the object itself. The appearance of an object may be either real or illusory, and the way in which an object may be perceived may change according to the subjective condition of the perceiver.
