Libertarianismevignette|Manifestation du Tea Party, un mouvement libertarien américain, en septembre 2009 à Washington Le libertarianisme, aussi appelé libertarisme, est une philosophie politique développée aux États-Unis. Elle repose sur l'idée qu'une société juste respecte et protège la liberté de chaque individu. Le libertarianisme repose sur l'émancipation qui s'oppose à l'assujettissement, d'où découlent une philosophie et une organisation de la vie en société permettant à chaque individu de jouir d'un maximum de liberté.
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.
Principe de non-agressionThe 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.
LibertéDe façon générale, la liberté est un terme qui désigne la possibilité d'action ou de mouvement. Pour le sens commun, la liberté s'applique principalement aux individus et s'oppose à la notion d'enfermement ou de séquestration. Une personne qui vient de sortir de prison est dite libre. Le sens original du mot liberté est d'ailleurs assez proche : l'homme libre est celui qui n'a pas le statut d'esclave. La liberté est un sujet difficile. Bien que tous aspirent à être libres, il y a presque autant de définitions de la liberté qu’il y a d’individus.
