Home Ancient Greek Scientists AGRICULTURALISTS ARCHITECTS ... PHYSICISTS MATHEMATICIAN ZENO OF ELEA (fl. 490 - 430 BC) Life Zeno was born in Elea, in Magna Graecia (south Italy). He was a disciple of Parmenides, the founder of the Eleatic School, whom he later succeeded as its head. His pupils included Pericles and later, in Athens, where he and Parmenides both went to teach, Socrates. He is cited by Plato, Heraclides Ponticus, Hermippus, Antisthenes, Stobaeus, Aristotle, Plutarch, Eudemus, Philo and Suidas. Work Zeno taught that there is no movement, and he proved it by 4 arguments, which are quoted by Aristotle in his "Physics". The first holds that, in order to cover a distance one must first cover half the distance, but in order to do that one must first cover half of that first half, and so on ad infinitum. This demonstrates that one can, therefore, never reach the goal, and in fact that there is no movement at all. The second is the example of Achilles, who can never catch up with the tortoise because he must first reach the point the tortoise started from, by which time the tortoise has moved on, and so forth. The third is the example of the arrow released from the bow, which is "proven" not to move at all, because each moment of time is made up of an infinite number of instants, indivisible and infinitely small. The fourth is the example of the two rows of bodies in the stadium, which he proposed as a mathematical proof of the non-existence of motion. Aristotle refuted Zeno's arguments, pointing out that "time is not made up of indivisible instants, any more than is any other magnitude".

This paradox makes a deluded classical presumption that reality is both an infinitely divisible spatial extensity and that infinitesimal reductions of that infinitely divisible extensity are demarcable by ideal 'dimensionless' classical 'points' and that a moving object can 'stop' at classically demarcated points. (Classically 'stop' means zero momentum Another way to make our statement is that this, Zeno's first, paradox assumes that classical motion and time are subject to analyticity.

Zeno met the young Socrates in 449 when he accompanied his teacher Parmenides to Athens. Zeno was tortured to death ( c. 435) for taking part in a political conspiracy against the city's tyrant Nearchus. Zeno's Race Course Infinite Sum Principle is valid, but either one of the premises is invalid or the premises are valid and the argument is unsound.

Zeno I interviewed the famous Zeno of Elea and talked to him about his life and mathematical achievements. He told me about his paradoxes. The interview follows this paragraph. Drew: So Zeno, if I may call you Zeno, where were you born and when? Zeno: Well Drew, I was born in the Greek Colony of Elea which is situated in southern Italy. I was born in about the year 495 B.C. Drew: So Zeno, did you have any real teachers or did you come up with your paradoxes on your own? Zeno: Actually, my first teacher was Parmenides, who was a philosopher. And with him I traveled to Athens where I met Socrates and eventually got into Plato's book Parmenides . Actually apart from what many think I am not a mathematician but a philosopher and logician. Drew: Then I guess we will have to change our column title, huh. Well back to math, what do you think is your best stumper for mathematicians? Zeno: Well, I would have to say that The Achilles is the best stumper. Drew: And how exactly does that go? Zeno: Well if you start a tortoise ahead of Achilles in a race, then Achilles will never get ahead of the tortoise. Drew: How is that possible? Isn't Achilles the fastest runner?

document.write(""); ZENO OF ELEA ZENGG(Hungarian, Zeng; Croatian, Senj; Italian, Segna), a royal free town of Hungary, in the county of Lika-Krbava, Croatia-Slavonia, 34 m. SE. of Fiume, on the Adriatic Sea. Pop. (1900) 3182. Zengg lies at the entrance to a long cleft among the Velebit Mountains, down which the bora, or N.N.E. wind, sweeps with such violence as often to render the harbour unsafe, although the Austrian Lloyd steamers call regularly. Apart from the cathedral of its Roman Catholic bishop, a gymnasium, and some ancient fortifications, the town contains little of interest. It carries on a small trade in tobacco, fish and salt. The island of Veglia faces the town and the port of San Giorgio lies 5 m. S. The captaincy of Zengg was established, in the 15th century, by King Matthias Corvinus of Hungary, as a check upon the Turks; and subsequently, until 1617, the town became famous as the stronghold of the Uskoks. ZENITH (from the Arabic), the point directly overhead; its direction is defined by that of the plumb-line. ZENJAN, or ZANJAN, a town of Persia, capital of the Khamseh province, about 205 m. N.W. of Teheran, on the high road thence to Tabriz, at an elevation of 5180 ft. It has a population of about 25,000 and post and telegraph offices, and was one of the original strongholds of the BábI sectarians, who held it against a large Persian force from May 1850 to the end of the year, when most of them were massacred. It has extensive gardens, well watered by the Zanjaneh river, which flows south of it. The well-stocked bazaar supplies the neighbouring d,istricts.

ZENO of Elea Ancient Greece, c. 449 BC ZENO (concluding): ...And so, through various irrefutable examples, I have succeeded in proving that motion does not exist. MAN: Hold on a second. Motion doesn't exist? ZENO: That's right. You see, if space can be divided into an infinite number of divisions, it will take an infinite amount of time to traverse them all. Therefore, all motion is just an illusion. The Olympic Games ANNOUNCER: And the runners are off! Achilles, the favorite from Parnassus, has taken an early lead...but oh, wait a second! He seems to be taking an infinite amount of time to cross the first yard of the track, as if movement itself were somehow impossible in a non-Parmenidean context! It looks like this veteran sprinter is headed for another heartbreak. ZENO (in the stands): I can't believe I bought tickets for this. The Athenian Senate SENATOR: I move that we adjourn until tomorrow. ZENO: Motion denied. (Giggles.) SENATOR: That's what you always say. In Line at the Multiplex GIRL: This is great I haven't been to the movies since "Schindler's List." Wasn't that film incredibly moving? ZENO: Moving? Mmmmm...No, I don't think so.

Back to Ancient History Sourcebook Ancient History Sourcebook: Zeno of Elea (c.490-after 445 BCE) Paradoxes Space. If there is such a thing as space, it will be in something, for all being is in something, and that which is in something is in some space. So this space will be in a space, and so on ad infinitum. Accordingly, there is no such thing as space. Motion The Arrow in Flight If, Zeno says, everything is at rest when it is in a space equal to itself, and the moving body is always in the present moment in a space equal to itself, then the moving arrow is still. Therefore the arrow in flight is stationary. The Race Course Motion does not exist because the moving body must go half the distance before it goes the whole distance. Achilles and the Tortoise The slow runner will never be overtaken by the swiftest, for it is necessary that the pursuer should first reach the point from which the pursued started, so that necessarily the slower is always somewhat in advance. This argument is the same as the preceding, the only difference being that the distance is not divided each time into halves. The Stadium With reference to equal bodies moving in opposite directions past equal bodies in the stadium with equal speed, some form the end of the stadium, others from the middle, Zeno thinks half the time equal to twice the time.

Zeno Of Elea (c. 495 BC-c. 430 BC), see also Eleaticism Greek philosopher and mathematician, whom Aristotle called the inventor of dialectic . He is especially known for his paradoxes that contributed to the development of logical and mathematical rigour and that were insoluble until the development of precise concepts of continuity and infinity. Zeno was famous for the paradoxes whereby, in order to recommend the Parmenidean doctrine of the existence of "the one" (i.e., indivisible reality), he sought to controvert the common-sense belief in the existence of "the many" (i.e., distinguishable qualities and things capable of motion). Zeno was the son of a certain Teleutagoras and the pupil and friend of Parmenides . In Plato's Parmenides, Socrates , "then very young," converses with Parmenides and Zeno, "a man of about forty"; but it may be doubted whether such a meeting was chronologically possible. Plato's account of Zeno's purpose (Parmenides), however, is presumably accurate. In reply to those who thought that Parmenides' theory of the existence of "the one" involved inconsistencies, Zeno tried to show that the assumption of the existence of a plurality of things in time and space carried with it more serious inconsistencies. In early youth he collected his arguments in a book, which, according to Plato, was put into circulation without his knowledge. Zeno made use of three premises:

Zeno of Elea (fl. c. 450 B.C.) Zeno was a fan of Parmenides and sought to "logically prove" Parmenides' big, stupid idea that All Is One (i.e., that there is but one single, motionless Being). This may be the beginning of the notorious tendency in the history of Philosophy to try to use formal logic to prove the utterly ridiculous. Inspired by Frege and the Principia Mathematica of Russell and Whitehead, the 20th century probably saw more of this crazy tendency than any time since Zeno himself rejoined the "universal Oneness." Daft Zeno stepped forward to say: "Before you can go all the way, You must get to the midpoint, ok? But before you can get quite that far You must first pass the quarterly bar, And before that the eighth, har, har, har! No matter how great your devotion Repeating this recursive notion You can never get started with motion." JSH, "Think Before You Step?" (1998) Return to Main Index z

I: An illusion? Z: Of course. In order to hear you, there would have to be a change from a state of no sound to a state of sound, which, as we all know, is impossible. I: Impossible? Really? How so? Z : Well, imagine a extremely small piece of wood dropping. Does it make a sound? No. So now imagine two extremely small pieces of wood. That would be two simultaneous occurrences, neither of which produce sound. Extend the argument... even a trillion pieces of wood would not make a sound, because one trillion times zero is no greater than two times zero. I: Oh... I see. But then how is it that I hear you and you hear me? Z: It's just an illusion. I: That's very interesting Zeno... Tell me - are there any other illusions other than sound?
