Q: Passage: Some civil disobedients feel it is incumbent upon them to accept punishment because of their belief in the validity of the social contract, which is held to bind all to obey the laws that a government meeting certain standards of legitimacy has established, or else suffer the penalties set out in the law. Other civil disobedients who favor the existence of government still don't believe in the legitimacy of their particular government, or don't believe in the legitimacy of a particular law it has enacted. And still other civil disobedients, being anarchists, don't believe in the legitimacy of any government, and therefore see no need to accept punishment for a violation of criminal law that does not infringe the rights of others. Question: What do some civil disobedient people feel the need to acknowledge.
A:
punishment
