Famous quotes containing the words magic and/or number:

    Until it is kindled by a spirit as flamingly alive as the one which gave it birth a book is dead to us. Words divested of their magic are but dead hieroglyphs.
    Henry Miller (1891–1980)

    The poetic act consists of suddenly seeing that an idea splits up into a number of equal motifs and of grouping them; they rhyme.
