“Our differences with [Joseph] Stalin are entirely of a strategical character.”

Only in the Fall of 1924 did [Joseph] Stalin discover that it is especially Russia, as distinguished from other countries, which can by its own forces build up a socialist society.

From being a patriotic myth, the Russian people have become an awful reality.

Once again, he who ignores the problems of revolutionary strategy would do better not to talk about revolutions at all.

Where force is necessary, there it must be applied boldly, decisively and completely.

If we had more time for discussion we should probably have made a great many more mistakes.

When one runs with the wolves, one must howl with the pack.

Under all conditions, well-organized violence seems to him the shortest distance between two points.

He who slanders the victim aids the executioner.

In a country where the sole employer is the State, opposition means death by slow starvation. The old principle: who does not work shall not eat, has been replaced by a new one: who does not obey shall not eat.

The fundamental flaw of vulgar thought lies in the fact that it wishes to content itself with motionless imprints of a reality which consists of eternal motion.

Workers – men and women – of all countries, place yourselves under the banner of the Fourth International. It is the banner of your approaching victory!

As long as human labor power, and, consequently, life itself, remain articles of sale and purchase, of exploitation and robbery, the principle of the “sacredness of human life” remains a shameful lie, uttered with the object of keeping the oppressed slaves in their chains.

You are pitiful isolated individuals; you are bankrupts; your role is played out. Go where you belong from now on – into the dustbin of history!

Fascism is nothing but capitalist reaction.

It is also false that the revolution ripens and comes to development only in the national soil.

‎The party that leans upon the workers but serves the bourgeoisie, in the period of the greatest sharpening of the class struggle, cannot but sense the smells wafted from the waiting grave.
