One hundred years after Lenin’s sealed train arrived at Finland Station and set into motion the events that led to Stalin’s gulags, the idea that we should return to this history for inspiration might sound absurd. But there was good reason that the Bolsheviks once called themselves “social democrats.” They were part of a broad movement of growing parties that aimed to fight for greater political democracy and, using the wealth and the new working class created by capitalism, extend democratic rights into the social and economic spheres, which no capitalist would permit.

The early Communist movement never rejected this broad premise. It was born out of a sense of betrayal by the more moderate left-wing parties of the Second International, the alliance of socialist and labor parties from 20 countries that formed in Paris in 1889. Across Europe, party after party did the unthinkable, abandoned their pledges to working-class solidarity for all nations, and backed their respective governments in World War I. Those that remained loyal to the old ideas called themselves Communists to distance themselves from the socialists who had abetted a slaughter that claimed 16 million lives. (Amid the carnage, the Second International itself fell apart in 1916.)

Of course, the Communists’ noble gambit to stop the war and blaze a humane path to modernity in backward Russia ended up seemingly affirming the Burkean notion that any attempt to upturn an unjust order would end up only creating another.

Most socialists have been chastened by the lessons of 20th-century Communism. Today, many who would have cheered on the October Revolution have less confidence about the prospects for radically transforming the world in a single generation. They put an emphasis instead on political pluralism, dissent and diversity.
