What is and what is not Parmenides?
Parmenides’ philosophy has been explained with the slogan “whatever is is, and what is not cannot be“. He is also credited with the phrase “out of nothing nothing comes”.

What is the Parmenides about?
Parmenides held that the multiplicity of existing things, their changing forms and motion, are but an appearance of a single eternal reality (“Being”), thus giving rise to the Parmenidean principle that “all is one.” From this concept of Being, he went on to say that all claims of change or of non-Being are illogical.

That is, the consequences contradict either what we have just assumed, or something we already know to be true (or, indeed, both) – we call this a contradiction.
Why do we use proof by contradiction?
