Ernesto Che Guevara fue un dirigente central de la vanguardia comunista de la Revolución Cubana forjada políticamente por Fidel Castro.

It's essential for working people to win state power, Che writes. "Then there's the second stage, maybe more difficult than the first"--the transition from dog-eat-dog capitalism to socialism. That includes moving from work as a compulsory condition of survival, to voluntary social labor through which we express our common humanity.

In the footsteps of Marx and Lenin, Che's efforts to lay the economic foundations of this historic transformation were hammered out in revolutionary struggle. They chart a road for working people everywhere to join in the fight for a socialist world. And, above all, to transform ourselves in the process.
