Formalism Quotes
Leninism is orthodox, obdurate, irreducible, but it does not contain so much as a hint of formalism, canon, not bureaucratism. In the struggle, it takes the bull by the horns. To make out of the traditions of Leninism a supra-theoretical guarantee of the infallibility of all the words and thoughts of the interpreters of these traditions, is to scoff at genuine revolutionary tradition and transform it into official bureaucratism. It is ridiculous and pathetic to try to hypnotize a great revolutionary party by repetition of the same formulae, according to which the right line should be sought not in essence of each question, not in the methods of posing and solving this question, but in formation of a biographical character.

After a few encounters of this kind, you got the idea: You had to be able to go back and forth with ease. Yet, in the last analysis, concepts took priority over formalism, the latter was simply an (indispensable) means to an end.
