The first of the four benefits of society conferred by Rousseau's Social Contract is that we are all equals and shall be treated as such. In this, he describes a general will which dictates the actions of the individual and basically the good of the whole is the good of its parts. Rousseau says, "Each of us puts in common his person and his whole power under the supreme direction of the general will; and in return we receive every member as an indivisible part of the whole" (Rousseau, p. 144).

According to Rousseau, once our minds are opened to this "new freedom", our own natural instincts will be developed and we shall finally become that which we were in the beginning, intelligent human beings.
