I became mentally bifocal, and so I learned early to understand that there is no such condition in human affairs as absolute truth. There is only truth as people see it, and truth, even in fact, may be kaleidoscopic in its variety. The damage such perception did to me I have felt ever since, although damage may be too dark a word, for it merely meant that I could never belong entirely to one side of any question. To be a Communist would be absurd to me, as absurd as to be entirely anything and equally impossible. I straddled the globe too young.
