Famous quotes containing the word decay:

    One of the most striking signs of the decay of art is the intermixing of different genres.
    Johann Wolfgang Von Goethe (1749–1832)

    But I must needs take my petulance, contrasting it with my accustomed morning hopefulness, as a sign of the ageing of appetite, of a decay in the very capacity of enjoyment. We need some imaginative stimulus, some not impossible ideal which may shape vague hope, and transform it into effective desire, to carry us year after year, without disgust, through the routine- work which is so large a part of life.
    Walter Pater (1839–1894)

    It had been a moving, tranquil apotheosis, immersed in the transfiguring sunset glow of decline and decay and extinction. An old family, already grown too weary and too noble for life and action, had reached the end of its history, and its last utterances were sounds of music: a few violin notes, full of the sad insight which is ripeness for death.
    Thomas Mann (1875–1955)
