Famous quotes containing the words challenge and/or rules:
“The very best reason parents are so special . . . is because we are the holders of a priceless gift, a gift we received from countless generations we never knew, a gift that only we now possess and only we can give to our children. That unique gift, of course, is the gift of ourselves. Whatever we can do to give that gift, and to help others receive it, is worth the challenge of all our human endeavor.”
—Fred Rogers (20th century)
“One might get the impression that I recommend a new methodology which replaces induction by counterinduction and uses a multiplicity of theories, metaphysical views, fairy tales, instead of the customary pair theory/observation. This impression would certainly be mistaken. My intention is not to replace one set of general rules by another such set: my intention is rather to convince the reader that all methodologies, even the most obvious ones, have their limits.”
—Paul Feyerabend (19241994)
