“A party which is always right must constantly define the correct line between sectarianism and opportunism. Where is this line situated? At an equal distance between the twin pitfalls of opportunism and sectarianism. But these pitfalls were themselves originally placed in relation to the correct line. The only way out of the vicious circle is a decree by the central authority which defines truth and error alike. And this decree is inevitably arbitrary, since it is made by a man who decides autocratically between individuals and groups; the disparity between the world as it would be if the original doctrine were true, and the world as it is, subordinates the truth to the equivocal and inscrutable decisions of an interpreter whose only qualification is his power.”
