Hence the sterile, uninspiring futility of a great many theoretical discussions of ethics, and the resentment which many people feel towards such discussions: moral principles remain in their minds as floating abstractions, offering them a goal they cannot grasp and demanding that they reshape their souls in its image, thus leaving them with a burden of undefinable moral guilt.

The only proper, moral purpose of a government is to protect man's rights, which means: to protect him from physical violence - to protect his right to his own life, to his own liberty, to his own property and to the pursuit of his own happiness.
