The liberal socialism is the theorethical-political formula that Carlo Rosselli (1899-1937) worked out between the 20´s and the 30´s, after a careful and the doctrines of the Italian socialism.
With Rosselli, socialism and liberalism came to a meeting point through a harsh criticism of marxism and by claiming democratic, pluralistic and voluntary character of socialism.
