Analysis of concept and components of equality principle in light of philosophical thoughts

Human beings have always sought to fight injustice and create equality for all in all areas of human life, including social, political, economic, religious, educational, and so on. Equality principle is one of the principles that contribute to realization of human aspirations. In philosophical and legal schools, the equality principle has been used to eliminate discrimination. One of the important influences of philosophical thought was its contribution to theoretical realization of the principle of equality, that is, it has applied this principle in different fields. Different philosophical theorists have tried to analyze this argument from their own point of view. The main objective of the paper is to examine the concept and components of equality principle in the light of philosophical thoughts, in order to illuminate its institutionalization in human rights instruments. The subject of the research is examined by a descriptive-analytical approach. Findings of the research show that philosophical ideas due to an important role playing in emergence and advancement of new legal institutions are considered as elements paving the way to institutionalize the principle of equality in legal systems and human rights instruments.
