The height of wisdom seems to me br That of a child; br So let my ageing vision be br Serene and mild. br The depth of folly, I aver, br Is to fish deep br In that dark pool of science where br Truth-demons sleep. br br Let me not be a bearded sage br Seeing too clear; br In issues of the atom age br Man-doom I fear. br So long as living's outward show br To me is fair, br What lies behind I do not know, br And do not care. br br Of woeful fears of future ill br That earth-folk haunt, br Let me, as radiant meadow rill, br Be ignorant.
