Long ago an honest scholar, my senior, said to me in reference to one who like himself is now no more, a man so unimpeachably respectable that against him nothing was ever openly said, though among the few something was whispered, ‘Yes, X---- is a nut not to be cracked by the tap of a lady’s fan. You are aware that I am the adherent of no organised religion, much less of any philosophy built into a system. Well, for all that, I think that to try and get into X----, enter his labyrinth, and get out again, without a clue derived from some source other than what is known as _knowledge of the world_, that were hardly possible, at least for me.’ ‘Why,’ said I, ‘X----, however singular a study to some, is yet human, and knowledge of the world assuredly implies the knowledge of human nature, and in most of its varieties.’ ‘Yes, but a superficial knowledge of it, serving ordinary purposes. But for anything deeper, I am not certain whether to know the world and to know human nature be not two distinct branches of knowledge, which while they may coexist in the same heart, yet either may exist with little or nothing of the other. Nay, in an average man of the world, his constant rubbing with it blunts that fine spiritual insight indispensable to the understanding of the essential in certain exceptional characters, whether evil ones or good. In a matter of some importance I have seen a girl wind an old lawyer about her little finger. Nor was it the dotage of senile love. Nothing of the sort. But he knew law better than he knew the girl’s heart. Coke and Blackstone hardly shed so much light into obscure spiritual places as the Hebrew prophets. And who were they? Mostly recluses.’ At the time my inexperience was such that I did not quite see the drift of all this. It may be that I see it now. And, indeed, if that lexicon which is based on Holy Writ were any longer popular, one might with less difficulty define and denominate certain phenomenal men. As it is, one must turn to some authority not liable to the charge of being tinctured with the Biblical element.
