Marxism is scientific truth and fears no criticism. If it did, and if it could be overthrown by criticism, it would be worthless. In fact, aren’t the idealists criticizing Marxism every day and in every way? And those who harbour bourgeois and petty-bourgeois ideas and do not wish to change — aren’t they also criticizing Marxism in every way? Marxists should not be afraid of criticism from any quarter. Quite the contrary, they need to temper and develop themselves and win new positions in the teeth of criticism and in the storm and stress of struggle. Fighting against wrong ideas is like being vaccinated — a man develops greater immunity from disease as a result of vaccination.
− Mao
‘An open mind is like a fortress with its gate unbarred and unguarded.’
‘Blessed is the mind too small for doubt.’
Im leaving my butthole unguarded
‘Courage comes from duty.’
