What is relieve oneself?

Famous quotes containing the words oneself and/or relieve:

    Of all the ways of acquiring books, writing them oneself is regarded as the most praiseworthy method.... Writers are really people who write books not because they are poor, but because they are dissatisfied with the books which they could buy but do not like.
    Walter Benjamin (1892–1940)

    The hounding of a dog pursuing a fox or other animal in the horizon may have first suggested the notes of the hunting-horn to alternate with and relieve the lungs of the dog. This natural bugle long resounded in the woods of the ancient world before the horn was invented.
    Henry David Thoreau (1817–1862)
