Famous quotes containing the words magic and/or number:

    There is no magic decoding ring that will help us read our young adolescent’s feelings. Rather, what we need to do is hold out our antennae in the hope that we’ll pick up the right signals.
    —The Lions Clubs International and the Quest Nation. The Surprising Years, III, ch.4 (1985)

    The said truth is that it is the greatest happiness of the greatest number that is the measure of right and wrong.
