If on one day we find the fast-spreading recognition of popular rights accompanied by a silent, growing perception of the rights of women, we also find it accompanied by a tendency towards a system of non-coercive education--that is, towards a practical illustration of the rights of children.

What, then, do they want a government for? Not to regulate commerce; not to educate the people; not to teach religion, not to administer charity; not to make roads and railways; but simply to defend the natural rights of man -- to protect person and property -- to prevent the aggressions of the powerful upon the weak -- in a word, to administer justice.
