The Hexameter Poem by Parmenides

Parmenides was securely identified with his city of elea, and his followers were often called the eleatics. According to parmenides, everything that exists is one; nothing ever changes or moves. Multiplicity of every sort is an illusion, whether it be the multiplicity of different objects, different colors, or different events happening at different times. All this is shown in his poem with a relentless chain of argument, which proceeds on the basis of pure reason rather than observations about the world around us.
