What is source?

Famous quotes containing the word source:

    You have never by a word or a deed given me one moment’s uneasiness; on the contrary I have felt perpetual gratitude to heaven for having given me, in you, a source of so much pure and unmixed happiness.
    Thomas Jefferson (1743–1826)

    The child knows only that he engages in play because it is enjoyable. He isn’t aware of his need to play—a need which has its source in the pressure of unsolved problems. Nor does he know that his pleasure in playing comes from a deep sense of well-being that is the direct result of feeling in control of things, in contrast to the rest of his life, which is managed by his parents or other adults.
    Bruno Bettelheim (20th century)

    The family: I believe more unhappiness comes from this source than from any other—I mean the attempt to prolong family connection unduly, and to make people hang together artificially who would never naturally do so.
    Samuel Butler (1835–1902)
