Man continually exchanges with man ideas and feelings, products and services.

Every discovery and act in society is necessary to him.

But of this immense quantity of products and ideas, that which each one has to produce and acquire for himself is but an atom in the sun.

Man would not be man were it not for society, and society is supported by the balance and harmony of the powers which compose it.
Society, among the animals, is SIMPLE; with man it is COMPLEX.

Man is associated with man by the same instinct which associates animal with animal; but man is associated differently from the animal, and it is this difference in association which constitutes the difference in morality.
I have proved,--at too great length, perhaps,--both by the spirit of the laws which regard property as the basis of society, and by political economy, that inequality of conditions is justified neither by priority of occupation nor superiority of talent, service, industry, and capacity.
