" The prophetic element in Marx’s creed was dominant in the minds of his followers. It swept everything else aside, banishing the power of cool and critical judgement and destroying the belief that by the use of reason we may change the world. All that remained of Marx’s teaching was the oracular philosophy of Hegel, which in its Marxist trappings threatens to paralyse the struggle for the open society. "
