Politics

for mankind always act in order to obtain that which they think good.

But justice is the bond of men in states,

and man is the only animal whom she has endowed with the gift of speech.

(for their nature attains to the perception of pleasure and pain and the intimation of them to one another, and no further),

The proof that the state is a creation of nature and prior to the individual is that the individual, when isolated, is not self-sufficing; and therefore he is like a part in relation to the whole.
