All totalitarianism of the twentieth century were predicated on a systematic, anti-individualistic collectivism. In the case of Marxist-Leninism, the source was classical Marxism. [Giovanni] Gentile had carefully dissected the neo-Hegelian roots of that collectivism. What he found missing in the collectivism of Marx was ethical concern. He sought to provide that concern to the collectivism of Fascism—a collectivism that shared a common intellectual origin with Marxism and Marxism-Leninism.
