Humane Quotes (page 12)
Humans! They lived in the world where the grass continued to be green and the sun rose every day and flowers regularly turned into fruit, and what impressed them? Weeping statues. And wine made out of water! A mere quantum-mechanistic tunnel effect, that'd happen anyway if you were prepared to wait zillions of years. As if the turning of sunlight into wine, by means of vines and grapes and time and anzymes, wasn't a thousand times more impressive and happened all the time...
Terry Prachett
Human manners are wildly inconsistent; plenty of people have said so. But this one takes the cake: the manner in which we're allowed to steal from future generations, while commanding them not to do that to us, and rolling our eyes at anyone who is tediously PC enough to point that out. The conspicious consumption of limited resources has yet to be accepted widely as a spirtual error, or even bad manners.
Barbara Kingsolver
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
