Neither man nor his community possesses any _absolute_ rights; they are all conditioned on how they are exercised. If they are not so conditioned they become privilege, which is a right not subject to conditions, and privilege is one of the things republicanism and democracy and every other effort towards human emancipation have set themselves up to destroy. Even the "right to life, liberty and the pursuit of happiness" is conditioned by the manner of use, and the same is true of every other and unspecified right. I do not propose to speak here of more than one aspect of this self-evident truth, but the single instance I cite is one that bears closely on the question of our industrial and economic situation; it is the responsibility to society of property or capital on the one hand and of labour on the other, when both invoke their "rights" to justify them in oppressing the general public in the pursuit of their own natural interests. During the Middle Ages, just as the political theory maintained that while a king ruled by divine right, this right gave him no authority to govern wrong, so the social theory held that while a man had a right to private property he had no right to use it against society, nor could the labourer use his own rights to the injury of the same institution. Power, property and labour must be used as a _function_, i.e., "an activity which embodies and expresses the idea of social purpose." Unless I am mistaken, this is at the basis of our "common law."
