Mariana Juan de (1536–1624), Spanish Jesuit historian and political philosopher. Born in Talavera de la Reina, he studied at Alcalá de Henares and taught at Rome, Sicily, and Paris. His political ideas are contained in De rege et regis institutione (‘On Kingship,’ 1599) and De monetae mutatione (‘On Currency,’ 1609). Mariana held that political power rests on the community of citizens, and the power of the monarch derives from the people. The natural state of humanity did not include, as Vitoria held, government and other political institutions. The state of nature was one of justice in which all possessions were held in common, and cooperation characterized human relations. Private property is the result of technological advances that produced jealousy and strife. Antedating both Hobbes and Rousseau, Mariana argued that humans made a contract and delegated their political power to leaders in order to eliminate injustice and strife. However, only the people have the right to change the law. A monarch who does not follow the law and ceases to act for the citizens’ welfare may be forcibly removed. Tyrannicide is thus justifiable under some circumstances. See also CONTRACTARIANISM , POLITICAL PHILOSO – PH. J.J.E.G. Maritain, Jacques (1882–1973), French Catholic philosopher whose innovative interpretation of Aquinas’s philosophy made him a central figure in Neo-Thomism. Bergson’s teaching saved him from metaphysical despair and a suicide pact with his fiancée. After his discovery of Aquinas, he rejected Bergsonism for a realistic account of the concept and a unified theory of knowledge, aligning the empirical sciences with the philosophy of nature, metaphysics, theology, and mysticism in Distinguish to Unite or The Degrees of Knowledge (1932). Maritain opposed the skepticism and idealism that severed the mind from sensibility, typified by the ‘angelism’ of Descartes’s intuitionism. Maritain traced the practical effects of angelism in art, politics, and religion. His Art and Scholasticism (1920) employs ancient and medieval notions of art as a virtue and beauty as a transcendental aspect of being. In politics, especially Man and the State (1961), Maritain stressed the distinction between the person and the individual, the ontological foundation of natural rights, the religious origins of the democratic ideal, and the importance of the common good. He also argued for the possibility of philosophy informed by the data of revelation without compromising its integrity, and an Integral Humanism (1936) that affirms the political order while upholding the eternal destiny of the human person.
