Who Was Zeno of Elea?
Zeno lived around 490-430 BC and was a student of Parmenides. He lived in Elea (now a region of Italy). He is best known for defending the work of Parmenides, who argued that all change was illusory (not real). The meaning of Zeno was his work throughout his life, centring around the invention of the dialectic. This is a method of argument in which you can uncover the truth, according to Zeno, by contradicting and reasoning against the accepted way of thinking. Doing this allowed him to ‘falsify’ accepted beliefs within his time.
There are no surviving copies of Zeno’s literature. Despite this, at least some of his work is explained to us by later philosophers who were friends or students of Zeno, particularly Aristotle.
What Was the Meaning of Zeno?
Zeno is best known for his paradoxes (a statement that appears false but is instead true). These are philosophical challenges that challenge human notions. Zeno used these to support Parmenides‘ claim that reality is unchanging. Some important examples are:
The Dichotomy Paradox:
To reach any destination, you must at some point be halfway there. You must also have been halfway to the halfway point, and so on. Motion seems impossible, as there are an infinite number of steps in the process to getting there.
Achilles and the Tortoise:
In a race, Achilles gives a tortoise a head start. Every time he reaches the tortoise’s previous position, it has moved forward some. Therefore, Achilles can never catch up with the tortoise. Obviously however, he does.
The Arrow Paradox:
An arrow in flight is always motionless at any specific point in time. If time is made up of specific moments, and in each moment the arrow does not move, then motion is a myth.
The Meaning of Zeno Stadium Paradox:
Objects moving at the same speed in opposite directions appear to pass each other faster than they should. This means relative assumptions of motion and time are incorrect.
Although Zeno’s paradoxes seem bizarre, they had meaning in questioning notions of time, motion and divisiblity.
The Meaning of Zeno in Philosophical Thought
The meaning of Zeno (and his work) lies in his use of logic to challenge common sense. By constructing the above paradoxes, he revealed the limits and inconsistency of our understandings of space and time. His paradoxes influenced numerous philosophers and mathematicians, including Aristotle, Kant, and 20th Century thinkers too, such as Bertrand Russell and Alfred North Whitehead. They helped in the development of physics and maths, particularly when questioning continuity, or infinite divisibility.
Zeno’s paradoxes invite us to think deeper about preconceived ‘truths’ – making us question our understandings of how the world works.
If you want to read about Zeno’s paradoxes further, I would recommend A Brief Guide to Smart Thinking by James M. Russell – which you can purchase at this link to support small bookshops in the UK.
