But you - you are trying to do it in a new way: you make no profit, your principles are communist, your ideals are splendid; they are written out so beautifully that you seem to be saints, that you should go to heaven while you are still alive. But can you get things done? We need a test, a real test, not the kind the Central Control Commission makes when it censures somebody and the All-Russia Central Executive Committee imposes some penalty. Yes, we want a real test from the view point of the national economy."

“Rectilinearity and one-sidedness, woodenness and petrification, subjectivism and subjective blindness — voilà the epistemological roots of idealism.”
