Famous quotes containing the word support:

    “There are so many intellectual and moral angels battling for rationalism, good citizenship, and pure spirituality; so many and such eminent ones, so very vocal and authoritative! The poor devil in man needs all the support and advocacy he can get. The artist is his natural champion. When an artist deserts to the side of the angels, it is the most odious of treasons.”
    —Aldous Huxley (1894–1963)
