“From whence are these "rights of individuals" derived, and why should we care? Unless we presume the existence of some greater power that determines what is good, isn't it arbitrary to posit that human survival is more important than private property rights, an equally artificially construed concept? Isn't it arbitrary to assume that some sort of equality is preferable to a system where, say, the poor are assumed to have bad karma? If these 'rights of individuals' are derived only from shared humanity, then do 'individuals' (a thoroughly meaningless term, by the way), begin to lose them when they act inhumanely? And isn't it totally arbitrary to grant rights to humans rather than other creatures anyway?”

Context: If all men are created equal, that is final. If they are endowed with inalienable rights, that is final. If governments derive their just powers from the consent of the governed, that is final. No advance, no progress can be made beyond these propositions. If anyone wishes to deny their truth or their soundness, the only direction in which he can proceed historically is not forward, but backward toward the time when there was no equality, no rights of the individual, no rule of the people. Those who wish to proceed in that direction can not lay claim to progress. They are reactionary. Their ideas are not more modern, but more ancient, than those of the Revolutionary fathers.

Part I : Declaration, Ch. IV : Mr. Spencer's Confusion as to Rights
A Perplexed Philosopher (1892)
Context: Men must have rights before they can have equal rights. Each man has a right to use the world because he is here and wants to use the world. The equality of this right is merely a limitation arising from the presence of others with like rights. Society, in other words, does not grant, and cannot equitably withhold from any individual, the right to the use of land. That right exists before society and independently of society, belonging at birth to each individual, and ceasing only with his death. Society itself has no original right to the use of land. What right it has with regard to the use of land is simply that which is derived from and is necessary to the determination of the rights of the individuals who compose it. That is to say, the function of society with regard to the use of land only begins where individual rights clash, and is to secure equality between these clashing rights of individuals.

The altruists, Christian or Maoist, agree. A cozy accomodation; and, I submit, a suspicious one. What if this antagonistic intedependence, this reciprocal reliance reflects and conceals an accord? Could egoism be altruism’s loyal opposition?
