Dissident thought takes many forms in opposition to dominance and consensus to promote social good. It includes challenging established doctrines through civil disobedience, protest, or subversive acts. In the Soviet Union, samizdat involved hand copying and distributing censored publications. Dissidence also occurs through public intellectualism and critique of power structures. It has a long history dating back to Russian nihilism and takes inspiration from philosophers like Nietzsche who disrupted traditional Western thought. Dissident thought is enabled by disagreement and negation as a condition of discourse.
