This is what they claim to be the origin and nature of justice; – it is a means or a compromise between the best of all, which consists in doing evil and not being punished, and the worst of all, which is to suffer injustice without the power of reprisals; and justice, which is at the center between the two, is tolerated not as a good, but as the lesser evil and honored because of the inability of people to do evil. For no man worthy of being called human would ever submit to such an agreement if he were able to resist; he would be angry if he did. This is the surviving account, Socrates, about the nature and origin of justice.  Pierre-Joseph Proudhon (1809-1865) advocated a conception of the social contract in which no individual surrenders his sovereignty to others. According to him, the social contract did not exist between individuals and the state, but between individuals who fail to force or govern each other, each retaining full sovereignty over themselves: according to the testamentary theory of contract, a contract is considered valid only if all parties voluntarily, tacitly or explicitly accept it. without coercion. Lysander Spooner, a lawyer from the 19th century. A strong advocate of a right to contract between individuals, he argued in his essay No Treason that a so-called social contract cannot be used to justify government measures such as taxes because the government will inject violence against anyone who does not want to enter into such a contract. Therefore, such an agreement is not voluntary and therefore cannot be considered a legitimate contract at all.
