( fl. 5th century bc), Greek philosopher. A member of the Eleatic school, he defended Parmenides' theories by formulating paradoxes that appeared to demonstrate the impossibility of motion.
His arguments are said to be more impressive than any that Parmenides created.
His conclusions are ridiculous...But it is hard to find any fault with his arguments.
Zeno argues that you can never get from one place to another. The "halving" argument. If you are always going half-way, you never reach your destination. Same argument - you can never actually even start for the wall. Because you need to go halfway... There is no motion. There is no change. The appearance of change is an illusion.
