“But we defend Jacobinism against the attacks, the calumny, and the stupid vituperations of anaemic, phlegmatic liberalism. The bourgeoisie has shamefully betrayed all the traditions of its historical youth, and its present hirelings dishonour the graves of its ancestors and scoff at the ashes of their ideals. The proletariat has taken the honour of the revolutionary past of the bourgeoisie under its protection. The proletariat, however radically it may have, in practice, broken with the revolutionary traditions of the bourgeoisie, nevertheless preserves them, as a sacred heritage of great passions, heroism and initiative, and its heart beats in sympathy with the speeches and acts of the Jacobin Convention.”

— Leon Trotsky, Results and Prospects (1906)
