" Man's potentialities are still more important, infinitely more important, than all his present achievements. This was so at the beginning and it still holds. His greatest problem has been how to selectively organize and consciously direct both the internal and external agents of the mind, so that they form more coherent and more intelligible wholes. Technics played a constructive part in solving this problem; but instruments of stone and wood and fiber could not be put to work on a sufficient scale until man had succeeded in inventing other impalpable tools wrought out of the very stuff of his own body, and not visible in any other form. "

― Lewis Mumford , Technics and Human Development (The Myth of the Machine, Vol 1)
