Famous quotes containing the word basis:

    Brutus. How many times shall Caesar bleed in sport,
    That now on Pompey’s basis lies along,
    No worthier than the dust!
    Cassius. So oft as that shall be,
    So often shall the knot of us be called
    The men that gave their country liberty.
    William Shakespeare (1564–1616)

    Painting dissolves the forms at its command, or tends to; it melts them into color. Drawing, on the other hand, goes about resolving forms, giving edge and essence to things. To see shapes clearly, one outlines them—whether on paper or in the mind. Therefore, Michelangelo, a profoundly cultivated man, called drawing the basis of all knowledge whatsoever.
    Alexander Eliot (b. 1919)

    The basis of shame is not some personal mistake of ours, but the ignominy, the humiliation we feel that we must be what we are without any choice in the matter, and that this humiliation is seen by everyone.
    Milan Kundera (b. 1929)
