LibertarianismLibertarianism (from libertaire, "libertarian"; from libertas, "freedom") is a political philosophy that upholds liberty as a core value. Libertarians seek to maximize autonomy and political freedom, and minimize the state's encroachment on and violations of individual liberties; emphasizing the rule of law, pluralism, cosmopolitanism, cooperation, civil and political rights, bodily autonomy, freedom of association, free trade, freedom of expression, freedom of choice, freedom of movement, individualism, and voluntary association.
Negative and positive rightsThe right of person A to obligate (enforce an obligation on) person B to refrain from (causal) physical interference with, in particular a purely interfering negligence tort against, some object or thing is called a negative right. So a negative right is a claim right. If a claim right is not a negative right, it is called a positive right. To every claim right of person A to obligate person B corresponds the obligation on B, so the obligation corresponding to a negative right is called a 'negative obligation' and an obligation corresponding to positive right a 'positive obligation'.
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.
Non-aggression principleThe non-aggression principle (NAP), also called the non-aggression axiom, is a concept in which aggression, defined as initiating or threatening any forceful interference (violating or breaching conduct) against an individual, their property, or promises (contracts) for which the aggressor is liable and in which the individual is a counterparty, is inherently wrong. There is no single or universal interpretation or definition of the NAP, with different definitions varying in regards to how to treat intellectual property, force, abortion, and other topics.
LibertyLiberty is the state of being free within society from oppressive restrictions imposed by authority on one’s way of life, behavior, or political views. In theology, liberty is freedom from the effects of "sin, spiritual servitude, [or] worldly ties". In economics, liberty means free, fair, and open competition, often referred to as a free market. Sometimes liberty is differentiated from freedom by using the word "freedom" primarily, if not exclusively, to mean the ability to do as one wills and what one has the power to do; and using the word "liberty" to mean the absence of arbitrary restraints, taking into account the rights of all involved.
