Objectivism and libertarianismAyn Rand's philosophy of Objectivism has been, and continues to be, a major influence on the right-libertarian movement, particularly libertarianism in the United States. Many right-libertarians justify their political views using aspects of Objectivism. Some right-libertarians, including Murray Rothbard and Walter Block, hold the view that the non-aggression principle is an irreducible concept: it is not the logical result of any given ethical philosophy, but rather is self-evident as any other axiom is.
Self-ownershipSelf-ownership, is the concept of property in one's own body, expressed as the moral or natural right of a person to have bodily integrity which means to be the exclusive controller of one's own body including one's life, where 'control' means exerting any physical interference and 'exclusive' means having the right to install and enforce a ban on other people doing this. Since the legal norm of property title claim incapacitates (or bans) other people (except the zygote) from claiming property title over the same resource at the same time, the right to control or interfere with one's own body in any arbitrary way is secured.
Natural rights and legal rightsSome philosophers distinguish two types of rights, natural rights and legal rights. Natural rights are those that are not dependent on the laws or customs of any particular culture or government, and so are universal, fundamental and inalienable (they cannot be repealed by human laws, though one can forfeit their enjoyment through one's actions, such as by violating someone else's rights). Natural law is the law of natural rights. Legal rights are those bestowed onto a person by a given legal system (they can be modified, repealed, and restrained by human laws).
Market anarchismMarket anarchism, also known as free-market anti-capitalism, is the branch of anarchism that advocates a free-market economic system based on voluntary interactions without the involvement of the state. A form of individualist anarchism, and libertarian socialism, it is based on the economic theories of mutualism and individualist anarchism in the United States. Samuel Edward Konkin III's agorism is a strand of left-wing market anarchism that has been associated with left-libertarianism.
Taxation as theftThe position that taxation is theft, and therefore immoral, is found in a number of political philosophies considered radical. It marks a significant departure from conservatism and classical liberalism. This position is often held by anarcho-capitalists, objectivists, most minarchists, anarchists, right-wing libertarians, and voluntaryists. Proponents of this position see taxation as a violation of the non-aggression principle. Under this view, government transgresses property rights by enforcing compulsory tax collection, regardless of what the amount may be.
PropertyProperty is a system of rights that gives people legal control of valuable things, and also refers to the valuable things themselves. Depending on the nature of the property, an owner of property may have the right to consume, alter, share, redefine, rent, mortgage, pawn, sell, exchange, transfer, give away, or destroy it, or to exclude others from doing these things, as well as to perhaps abandon it; whereas regardless of the nature of the property, the owner thereof has the right to properly use it under the granted property rights.
Negative libertyNegative liberty is freedom from interference by other people. Negative liberty is primarily concerned with freedom from external restraint and contrasts with positive liberty (the possession of the power and resources to fulfill one's own potential). The distinction originated with Bentham, was popularized by T.H. Green and Guido De Ruggiero, and is now best known through Isaiah Berlin's 1958 lecture "Two Concepts of Liberty". Stanford Encyclopedia of Philosophy describes negative liberty: "The negative concept of freedom .
Law of equal libertyThe law of equal liberty is the fundamental precept of liberalism and socialism. Stated in various ways by many thinkers, it can be summarized as the view that all individuals must be granted the maximum possible freedom as long as that freedom does not interfere with the freedom of anyone else.
Private defense agencyA private defense agency (PDA) is a theoretical enterprise which would provide personal protection and military defense services to individuals who would pay for its services. PDAs are advocated in anarcho-capitalism as a way of enforcing the system of private property. A PDA is distinguished from a private contractor employed by a state which is usually subsidized. Instead, such agencies would in theory be voluntarily financed primarily by competing insurance and security companies.
Natural-rights libertarianismNatural-rights libertarianism (also known as deontological liberalism, deontological libertarianism, libertarian moralism, natural rights-based libertarianism, philosophical libertarianism or rights-theorist libertarianism) is the theory that all individuals possess certain natural or moral rights, mainly a right of individual sovereignty and that therefore acts of initiation of force and fraud are rights-violations and that is sufficient reason to oppose those acts.
