The universal basis of co-operation is the proportioning of benefits received to services rendered. - Herbert Spencer

The education of the child must accord both in mode and arrangement with the education of mankind, considered historically. In other words, the genesis of knowledge in the individual, must follow the same course as the genesis of knowledge in the race. In strictness, this principle may be considered as already expressed by implication; since both being processes of evolution, must conform to those same general laws of evolution... and must therefore agree with each other. Nevertheless this particular parallelism is of value for the specific guidance it affords. To M. Comte we believe society owes the enunciation of it; and we may accept this item of his philosophy without at all committing ourselves to the rest.

As a corollary to the proposition that all institutions must be subordinated to the law of equal freedom, we cannot choose but admit the right of the citizen to adopt a condition of voluntary outlawry. If every man has freedom to do all that he wills, provided he infringes not the equal freedom of any other man, then he is free to drop connection with the state — to relinquish its protection, and to refuse paying towards its support. It is self-evident that in so behaving he in no way trenches upon the liberty of others; for his position is a passive one; and whilst passive he cannot become an aggressor. It is equally selfevident that he cannot be compelled to continue one of a political corporation, without a breach of the moral law, seeing that citizenship involves payment of taxes; and the taking away of a man's property against his will, is an infringement of his rights. Government being simply an agent employed in common by a number of individuals to secure to them certain advantages, the very nature of the connection implies that it is for each to say whether he will employ such an agent or not. If any one of them determines to ignore this mutual-safety confederation, nothing can be said except that he loses all claim to its good offices, and exposes himself to the danger of maltreatment — a thing he is quite at liberty to do if he likes. He cannot be coerced into political combination without a breach of the law of equal freedom; he can withdraw from it without committing any such breach; and he has therefore a right so to withdraw.

Every pleasure raises the tide of life; every pain lowers the tide of life.
