Locke’s departs from the characteristics of human being and of the natural life to construct his political thought. In this thought, human individual is not created to live alone: s/he has to live in a society. The first society is constituted of the relationship between women and men. The society of parents and children follows the former, and the society of masters and slaves comes. These societies, however, differ from political societies in their aims and the responsibilities of their members. Human being, as a social being, is naturally equal and free. Locke claims that reason in the natural state teach all individuals that they are equal and free, and that they must not harm each other’s freedom, life, welfare and property. Individuals are also a part of God’s creation, and God directs them to good. Human beings, differently from any other animals, have reason and conscience. Human nature, therefore, is a virtuous combination of many elements, potentially: Moral, reasonable, egoist, and social elements.
