Parmenides was a Greek philosopher who was born in Elea, Italy. He is best known for his work ‘On Nature’, in which he argues that the only thing that exists is the One.
In fact, Parmenides was born around 515 BC and founded a school of philosophy at Elea, near Naples. He wrote a book called On Nature (also known as The Way of Truth) in which he tried to explain the nature of reality.
Actually, Parmenides believed that there were two kinds of reality: one being eternal and unchanging, and the other being temporary and always changing. He argued that the world we see around us is actually an illusion created by our senses. This theory of perception laid the foundations for Plato’s theory of forms.
According to Parmenides, everything we can perceive through our senses or think about is made up of two things: matter (what we can feel) and form (our ideas). These two things are separate entities; they exist independently from each other but they must go together if anything is going to exist at all. For example, if you see a tree then there must be both a tree-shaped form and matter (the wood) which makes up this form.
