"Remember Lenin, who (be it said for all
Popperian lovers of ‘falsification’) alloted to error a privileged role in the process of the rectification of knowledge, to the point where
he conferred on it, with respect to scientific experiment and political
practice, a kind of heuristic primacy over ‘truth’: how many times
did he repeat that it is worse to blind yourself and keep silent about
a defeat than to suffer it, that it is worse to close your eyes to an
error than to commit it" - Louis Althusser, "Unfinished History"
