Famous quotes containing the word composition:

    The naive notion that a mother naturally acquires the complex skills of childrearing simply because she has given birth now seems as absurd to me as enrolling in a nine-month class in composition and imagining that at the end of the course you are now prepared to begin writing War and Peace.
    Mary Kay Blakely (20th century)

    Vices enter into the composition of virtues as poisons into the composition of certain medicines. Prudence and common sense mix them together, and make excellent use of them against the misfortunes that attend human life.
    François, Duc De La Rochefoucauld (1613–1680)

    Those Dutchmen had hardly any imagination or fantasy, but their good taste and their scientific knowledge of composition were enormous.
    Vincent Van Gogh (1853–1890)
