 Italian philosophers were also influential in the development of the non-Marxist liberal socialism philosophy, including Carlo Rosselli, Norberto Bobbio, Piero Gobetti and Aldo Capitini.In the 1960s, many Italian left-wing activists adopted the anti-authoritarian pro-working class leftist theories that would become known as autonomism and "operaismo".Early and important Italian feminists include Sibilla Aleramo, Alaide Gualberta Beccari, and Anna Maria Mozzoni, though proto-feminist philosophies had previously been touched upon by earlier Italian writers such as Christine de Pizan, Moderata Fonte, and Lucrezia Marinella.
