Actual idealism is a form of idealism, developed by Giovanni Gentile, that grew into a "grounded" idealism, contrasting the transcendental idealism of Immanuel Kant, and the absolute idealism of G. W. F. Hegel. To Gentile, who considered himself the "philosopher of fascism" while simultaneously describing himself as liberal and socialist, actualism was presented the sole remedy to philosophically preserving free agency, by making the act of thinking self-creative and, therefore, without any contingency and not in the potency of any other fact.

Giovanni Gentile was an Italian philosopher, fascist politician, and pedagogue.
