Fusionism is an American political term for the philosophical and political combination or "fusion" of traditionalist and social conservatism with political and economic right-libertarianism. The philosophy is most closely associated with Frank Meyer.
The philosophy of "fusionism" was developed at National Review magazine during the 1950s under the editorship of William F. Buckley, Jr. and is most identified with his associate editor Frank Meyer. As Buckley recounted the founding he "brokered" between "an extraordinary mix" of libertarians, traditional conservatives, anti-communists and even an anarchist to produce the ideas and writings that produced modern conservatism. He identified Meyer's synthesis as the most likely best solution of defining conservatism.
In his most influential book, In Defense of Freedom, Meyer defined freedom in what Isaiah Berlin would label "negative" terms as the minimization of the use of coercion by the state in its essential role of preventing one person's freedom from intruding upon another's. The state should protect freedom but otherwise leave virtue to individuals. The state has only three legitimate functions – police, military and operating a legal system, all necessary to control coercion, which is immoral if not restricted. Virtue is critical for society and freedom must be balanced by responsibility but both are inherently individual in form. Coerced values cannot be virtuous. Freedom by itself has no goal, no intrinsic end. Freedom is not abstract or utopian as with the utilitarians, who also make freedom an end rather than a means. In a real society traditional order and freedom can only exist together. The solution is a philosophical synthesis of both freedom and tradition, the solution to the dilemma is "grasping it by both horns" and accepting the tension between the two.
Fusionism's most famous advocate was Ronald Reagan as an early admirer of National Review and associate of both editors. On assuming the presidency in 1981, he met with conservative leaders around the country in Washington and reminded them of their intellectual roots. After listing "intellectual leaders like Russell Kirk, Friedrich Hayek, Henry Hazlitt, Milton Friedman, James Burnham, [and] Ludwig von Mises" as the ones who "shaped so much of our thoughts," he discussed only one of these influences at length:
