Justice in philosophy, is the concept of the proper proportion between a person’s deserts (what is merited) and the good and bad things that befall or are allotted to him or her.

For him (Aristotle), the key elements of justice is treating like cases alike, an idea that has set later thinkers the task of working out which similarities (need, desert, talent) are relevant.The concept of the justice is as old as the origin and growth of human society.
