"One must not fear criticism, or gloss over shortcomings; on the contrary, it is necessary to help to make them known and to see nothing discreditable in doing so. Only he can be discredited who conceals his shortcomings, who is unwilling to fight against evils, that is, precisely the man who ought to be discredited. It is necessary to be able to see the truth and to imbibe it from the masses and from all who are taking part in production. There is nothing worse than self-praise and self-satisfaction. It is possible to go forward only when, step by step, evils are sought out and overcome."
