The party must fight with all its power and with every necessary strategy against the attempt to isolate it and throw its energy back upon itself. Th… - James Patrick Cannon

Without revolutionary theory, the workers, even with the best will in the world, cannot fight the capitalist system successfully. This statement holds good, not merely in the question of the final revolutionary struggle for power, it applies equally in every aspect of the daily struggle. Workers who have no understanding of the theory of revolution cannot follow a consistent line of action that leads toward it. Behind every action aimed at the bourgeoisie, there must be the theory of the revolutionary overthrow of the bourgeoisie. False policies in the ranks of the workers, whereby even their own good will and energy is transformed into a force operating against their own interests, spring in the first place from false theory. Only by an understanding of the revolutionary nature of their struggle, and of the necessity of shaping their actions in the light of this theory and adapting them to the execution of it, can the workers follow a systematic policy of opposition to the bourgeoisie and of defense of their own interests. Revolutionary theory is not something separate from action, but is the guiding principle of all revolutionary action.

Trotskyism is not a new movement, a new doctrine, but the restoration, the revival of genuine Marxism as it was expounded and practiced in the Russian revolution and in the early days of the Communist International.

Recoiling against the cult of Stalin, which caused such devastation in the American radical movement, some people now describe all reference to the Marxist authorities as the cult of Marx, the cult of Lenin, or the cult of Trotsky. Those who used to forbid themselves to say anything until it was first said by Stalin, or even to think any thoughts which had not first been thought for them by Stalin, have suddenly decided that the cure for this mental, moral and political prostration is to listen to nothing that is said and to read nothing that has been written outside the borders of the fifty states.
