“It is not the truth of Marxism that explains the willingness of 
intellectuals to believe it, but the power that it confers on 
intellectuals, in their attempts to control the world. And since...it is 
futile to reason someone out of a thing that he was not reasoned into, 
we can conclude that Marxism owes its remarkable power to survive every 
criticism to the fact that it is not a truth-directed but a 
power-directed system of thought.”
Sir Roger Scruton
