Tehran, Iran Reza Davari Ardakani Professor of Islamic Azad University. Science and Research Branch. Tehran, Iran Journal Article 2017 11 28 All kinds of identity are typical, genus, and numerical identity. This predication that is the basis of the propositional language of Aristotle is the condition of speaking and use of categories and general concepts in the realm of beings. Because of this, these categories are called categories of being. Before we can speak of prediction, everything must be self-identical. So we have now the best known and logical form of the principle of identity i.e. A=A. Aristotle with formulating the logic and with a concentrate on the numerical identity leads to a kind of concept of the world i.e. conceptual-logical world. The world, after that, is the world of mind and logical thought. With the superiority of the numerical identity and constitution of the principle of identity, the nature of categories is logical-Mindy nature. The definition of identity as A=A give rise to man solely directed at the logical form of this principle and will wipe out of ontological sense. So this particular view about identity leads to a formulation of logical-mindy nature of categories. All kinds of identity are typical, genus, and numerical identity.
