If we make sacrifices in doing good or in doing ill, it does not alter the ultimate value of our actions; even if we stake our life in the cause, as martyrs do for the sake of our church : it is a sacrifice to our longing for power, or for the purpose of conserving our sense of power.
Friedrich NietzscheQuidquid luce fuit tenebris agit: but also the other way around. What we experience in dreams, so long as we experience it frequently, is in the end just as much a part of the total economy of our soul as anything we "really" experience: because of it we are richer or poorer, are sensitive to one need more or less, and are eventually guided a little by our dream-habits in broad daylight and even in the most cheerful moments occupying our waking spirit.
Friedrich Nietzsche
