The Roots of the Absolute Non-Existent Paradox in Greek Philosophy

For Different thinkers، throughout history، ‘The unknowable non-existent’ has had different meanings. However، despite these differences، the ordinary absolute non-existent in Muslim philosophy (ma‘dūm muṭlaq; non-existent in both the external world and in the mind)، can be expressed in this way: absolute non-existent is never existed in external world or in mind (rather it is impossible to be conceived in the mind)، neither detailedly nor un-detailedly، neither in perception nor in imagination and intellect. ‘The absolute non-existent’ leads us to a paradox which is usually called the paradox of informing from absolute non-existent; suppose that (P) is ‘The absolute nonexistent is unknowable’، since the very P is a kind of knowledge or information about the absolute nonexistent، so we are encountered to a paradox. In this paper I explore the roots of the ‘absolute nonexistent’ and the paradox in Greek philosophy; actually in Parmenides and Plato.
