Famous quotes containing the words source and/or heat:

    Thought is the work of the intellect, reverie is its self-indulgence. To substitute day-dreaming for thought is to confuse a poison with a source of nourishment.
    Victor Hugo (1802–1885)

    For my part, when I enter most intimately into what I call myself, I always stumble on some particular perception or other, of heat or cold, light or shade, love or hatred, pain or pleasure. I never can catch myself at any time without a perception, and never can observe anything but the perception.
    David Hume (1711–1776)
