Factions are a sign of illness in a party.

Socialist democracy is not, a luxury and its need is not limited to the most advanced industrial countries.

You cannot make a socialist revolution without really trying.

You need a vanguard organization in order to overcome the dangerous potential brought about by the uneven development of class militancy and class consciousness.

Periodically, the workers do revolt against bourgeois society, not by a hundred, five hundred, or a thousand, but by the millions.

Only under conditions of revolutionary crises do you have the highest level of self-organization; this is the Soviet type of organization, which is to say, workers' councils, people's councils, call them what you want, popular committees.

Revolution is an instrument, like a party is an instrument.
