  Zeno of Elea - Wikipedia, the free encyclopedia
Zeno of Elea should not be confused with Zeno of Citium.
Zeno's arguments are perhaps the first examples of a method of proof called Reductio ad absurdum, also known as proof by contradiction.

He is said to have been concerned in a plot against a tyrant, and on its detection to have borne with exemplary constancy the tortures to which he was subjected; but authorities differ both as to the name and the residence of the tyrant and as to the circumstances and the issue of the enterprise.
In reply to those who thought that Parmenidess theory of the existence of the One involved inconsistencies and absurdities, Zeno tried to show that the assumption of the existence of the Many, that is to say, a plurality of things in time and space, carried with it inconsistencies and absurdities grosser and more numerous.
Of the paradoxes used by Zeno to discredit the belief in plurality and motion, eight survive in the writings of Aristotle and Simplicius.

The chief doctrine of the school was the oneness and immutability of reality and the distrust of sense-knowledge which appears to testify to the existence of multiplicity and change.
Zeno's contribution to the literature of the school consisted of a treatise, now lost, in which, according to Plato, he argued indirectly against the reality of motion and the existence of the manifold.
They earned for Zeno the title of "the first dialectician," and, because they seemed to be an unanswerable challenge to those who relied on the verdict of the senses, they helped to prepare the way for the skepticism of the Sophists.

 Encyclopedia Uselessia -- Zeno of Elea's Paradoxes
Zeno of Elea is famous for his paradoxes.
Zeno's paradoxes are a set of paradoxes devised to support Parmenides' doctrine that "all is one" and that contrary to the evidence of our senses, the belief in plurality and change is mistaken, and in particular that motion is nothing but an illusion.
Zeno's paradox however implies that if Zeno's method is followed to its logical extent, concepts such as velocity lose all meaning and there is no causal agent that is not similarly affected by the paradox that could enable the arrow to progress.

The great Greek philosopher Zeno of Elea (born sometime between 495 and 480 B.C.) proposed four paradoxes in an effort to challenge the accepted notions of space and time that he encountered in various philosophical circles.
Zeno's paradoxes focus on the relation of the discrete to the continuous, an issue that is at the very heart of mathematics.
Zeno's first paradox attacks the notion held by many philosophers of his day that space was infinitely divisible, and that motion was therefore continuous.

 Zeno's Paradoxes
Second, from this Zeno argues that it follows that they do not exist at all; since the result of joining (or removing) a sizeless object to anything is no change at all, he concludes that the thing added (or removed) is literally nothing.
Thus we answer Zeno as follows: the argument assumed that the size of the body was a sum of the sizes of the point parts, but that is not the case; according to modern mathematics, a line is an uncountable infinity of points plus a distance function.
Zeno abolishes motion, saying "What is in motion moves neither in the place it is nor in one in which it is not".

Zeno is most well-known for his four paradoxes of motion, which argue against the possibility of motion as we see it.
Each of Zeno's paradoxes can be explained in some way by more modern concepts of thought and motion, and they have been further explained and analysed from Aristotle's time to the modern day.

According to Plato, Zeno confesses, in response to the dogged questioning of the latter's young Socrates, to have composed in his collection of paradoxes of plurality simply in defense of Parmenides, who had been coming under heavy ridicule for his position regarding the one.

Zeno argues that it is impossible for a runner to traverse a race course.
Since Zeno was generalizing about all motion, his conclusion was either (a) that no motion could be completed or (b) that no motion could be begun.
Aristotle assumed that (b) was what Zeno intended (and he based his refutation on that assumption).

The Paradoxa of Zeno of Elea are an example of ancient Greek abstract reasoning that is even in contradiction to observation.
Zeno bases both the dichotomy paradox and the attack on simple pluralism on the fact that once a thing is divisible, then it is infinitely divisible.
Zeno thinks that we cannot have different results that depend on the observer and thus any movement is an illusion.

Zeno's problem demands some consideration; if all being is in some place, evidently there must be a place of this place, and so on indefinitely.
Zeno presents four arguments concerning motion which involve puzzles to be solved, and the first of these shows that motion does not exist because the moving body must go half the distance before it goes the whole distance; of this we have spoken before (Phys.

 Zeno of Elea [Internet Encyclopedia of Philosophy]
We learn from Plato that Zeno was twenty-five years younger than Parmenides, and he wrote his defense of Parmenides as a young man. Because only a few fragments of Zeno's writings have been found, most of what we know of Zeno comes from what Aristotle said about him in Physics, Book 6, chapter 9.
Both groups of Zeno's arguments, those against multiplicity and those against motion, are variations of one argument that applies equally to space or time.
