Russell: I told him he not simply to state what he thinks true, but to give arguments for it, but he said arguments spoil its beauty, and that he would feel as if was dirtying a flower with muddy hands. He does appear to me – the artist in intellect is so very rare. I told him I hadn’t the heart to say anything against that, and that he had better acquire a slave to state the arguments. I am seriously afraid that no one will see the point of anything he writes, because he won’t recommend it by arguments addressed to a different point of view.
