Although I am not a legalist when it comes to the conquest of power, I am one when it comes to the exercise of power. If parliamentary processes result in our being called upon to exercise power within the framework of existing institutions, we should do so legally and fairly without taking advantage of our presence in government to fraudulently transform the exercise of power into the conquest of power.

Quoted in Jean Lacouture, Léon Blum (1979), p. 206.
