But either these treaties and agreements distributed wealth equally, as did the original communism (the only method of distribution with which the barbarians were acquainted, and the only form of justice of which they could conceive; and then the question of origin assumes this form: how did equality afterwards disappear ?)--or else these treaties and agreements were forced by the strong upon the weak, and in that case they are null; the tacit consent of posterity does not make them valid, and we live in a permanent condition of iniquity and fraud.
We never can conceive how the equality of conditions, having once existed, could afterwards have passed away.

What was the cause of such degeneration?
The instincts of the animals are unchangeable, as well as the differences of species; to suppose original equality in human society is to admit by implication that the present inequality is a degeneration from the nature of this society,--a thing which the defenders of property cannot explain.

But I infer therefrom that, if Providence placed the first human beings in a condition of equality, it was an indication of its desires, a model that it wished them to realize in other forms; just as the religious sentiment, which it planted in their hearts, has developed and manifested itself in various ways.

Man has but one nature, constant and unalterable: he pursues it through instinct, he wanders from it through reflection, he returns to it through judgment; who shall say that we are not returning now?
According to Grotius, man has abandoned equality; according to me, he will yet return to it.

How came he to abandon it?
Why will he return to it?
These are questions for future consideration.
