“The soul active sees absolute truth; and utters truth, or creates.”

Context: Science makes no pretension to eternal truth or absolute truth; some of its rivals do. That science is in some respects inhuman may be the secret of its success in alleviating human misery and mitigating human stupidity.

Context: 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.
