...the end result of the adoption of permaculture strategies in any country or region will be to dramatically reduce the area of the agricultural environment needed by the households and the settlements of people, and to release much of the landscape for the sole use of wildlife and for re-occupation by endemic flora.
Bill Mollison
Not only must weapons be bought and paid for out of surpluses of capital and labour, but they must also be put to use. For this is the only means that capitalism has at its disposal to achieve the level of devaluation now required. The idea is dreadful in its implications. What better reason could there be to declare that it is time for capitalism to be gone, to give way to some saner mode of production?
David Harvey
The very general occurrence of the homosexual in ancient Greece, and its wide occurrence today in some cultures in which such activity is not taboo suggests that the capacity of an individual to respond erotically to any sort of stimulus, whether it is provided by another person of the same or opposite sex, is basic in the species.
Alfred Kinsey
I can remember how when I was young I believed death to be a phenomenon of the body now I know it to be merely a function of the mind -- and that of the minds who suffer the bereavement. The nihilists say it is the end the fundamentalists, the beginning when in reality it is no more than a single tenant or family moving out of a tenement or a town.
William Faulkner
The more we learn of the true nature of non-human animals, especially those with complex brains and corresponding complex social behavior, the more ethical concerns are raised regarding their use in the service of man - whether this be in entertainment, as "pets," for food, in research laboratories, or any of the other uses to which we subject them.
Jane Goodall
