Approximately Quotes (page 2)
Human knowledge is not (or does not follow) a straight line, but a curve, which endlessly approximates a series of circles, a spiral. Any fragment, segment, section of this curve can be transformed (transformed one-sidedly) into an independent, complete, straight line, which then (if one does not see the wood for the trees) leads into the quagmire, into clerical obscurantism (where it is anchored by the class interests of the ruling classes).
Vladimir Lenin
[However], the sufferer from depression has no option, and therefore finds himself, like a walking casualty of war, thrust into the most intolerable social and family situations. There he must ... present a face approximating the one associated with ordinary events and companionship. He must try to utter small talk and be responsive to questions, and knowingly nod, and frown and, God help him, even smile.
William Styron
