The meaning of justice can be defined according to a juridical, human, theological, ethical, biomedical, or social perspective. It should guarantee the protection of life and health, personal, civil, political, economic, and religious rights, as well as non-discrimination, inclusion, protection, and access to care. In this review, we deal with three theoretical concepts that define justice in all its aspects. (1) The utilitarian theory, which justifies moral statements on the basis of the evaluation of the consequences that an action produces, elaborating a pragmatic model of medical science. (2) The libertarian theory, which considers freedom as the highest political aim, thus absolutizing the rights of the individual; here, the principle of self-determination, with respect to which the principle of permission/consent is the fundamental presupposition, plays a central role in the definition of the person. (3) The iusnaturalist theory, in which man’s moral freedom is identified with the ability to act by choosing what the intellect indicates to him as good; the natural moral law that drives every conscience to do good is therefore realized in respect for the person in the fullness of his rights. In conclusion, different forms and conceptions of justice correspond to different organizations of society and different ways of addressing ethical issues in the biomedical domain.
