Zeno was an ancient Greek philosopher from the city of Elea, known for founding the philosophical school of Eleaticism. He lived around the 5th century BCE and is best known for his paradoxes, which challenge our understanding of motion and change. His most famous paradoxes include the Achilles and the Tortoise and the Dichotomy Paradox, which argue that motion is impossible because it requires completing an infinite number of tasks. Zeno's work aimed to defend the teachings of his mentor, Parmenides, who argued that reality is unchanging and that our perceptions of change are illusory. Although none of Zeno's writings survive in complete form, his ideas have significantly influenced later philosophers and mathematicians, including Aristotle and Kant.
