Marxism must abhor nothing so much as the possibility that it becomes congealed in its current form. It is at its best when butting heads in self-criticism, and in historical thunder and lightning, it retains its strength.

The most revolutionary thing one can do is always to proclaim loudly what is happening.

There is no democracy without socialism, and no socialism without democracy.

Those who do not move, do not notice their chains.

Freedom is always the freedom of dissenters.

Bourgeois society stands at the crossroads, either transition to socialism or regression into barbarism.

Freedom only for supporters of the government, only for the members of one party - however numerous they may be - is no freedom at all. Freedom is always and exclusively freedom for the one who thinks differently. Not because of any fanatical concept of 'justice' but because all that is instructive, wholesome and purifying in political freedom depends on this essential characteristic, and its effectiveness vanishes when 'freedom' becomes a special privilege.
