The poet goes on to make the solitary man say, "My right there is none to dispute." The condition of Alexander Selkirk was unquestionably one of absolute liberty. His rights were not measured by his duties. He had all rights and no duties. Many writers on the origin of society have held that man, upon entering into union with his fellow-men, and submitting, as a necessary consequence of this union, to the restraints of law and government, sacrifices a portion of his liberty, or natural power, for the security of that power which remains to him. No such agreement amongst mankind could ever have possibly taken place; for man is by his nature, and without any agreement, a social being. He is a being whose rights are balanced by the uncontrollable force of their relation to the rights of others. The succour which the infant man requires from its parents, to an extent, and for a duration, so much exceeding that required for the nurture of other creatures, is the natural beginning of the social state, established insensibly and by degrees. The liberty which the social man is thus compelled by the force of circumstances to renounce amounts only to a restraint upon his brute power of doing injury to his fellow-men: and for this sacrifice, in itself the cause of the highest individual and therefore general good, he obtains that dominion over every other being, and that control over the productive forces of nature, which alone can render him the monarch of all he surveys. The poor sailor, who for four years was cut off from human aid, and left alone to struggle for the means of supporting existence, was an exception, and a very rare one, to the condition of our species all over the world. His absolute rights placed him in the condition of uncontrolled feebleness; if he had become social, he would have put on the regulated strength of rights balanced by duties.
