Thus Spake Zarathustra ― A Book for All and None

People commended unto Zarathustra a wise man, as one who could discourse well about sleep and virtue: greatly was he honoured and rewarded for it, and all the youths sat before his chair. To him went Zarathustra, and sat among the youths before his chair. And thus spake the wise man: Respect and modesty in presence of sleep! That is the first thing! And to go out of the way of all who sleep badly and keep awake at night! Modest is even the thief in presence of sleep: he always stealeth softly through the night. Immodest, however, is the night-watchman; immodestly he carrieth his horn. No small art is it to sleep: it is necessary for that purpose to keep awake all day. Ten times a day must thou overcome thyself: that causeth wholesome weariness, and is poppy to the soul. Ten times must thou reconcile again with thyself; for overcoming is bitterness, and badly sleep the unreconciled. Ten truths must thou find during the day; otherwise wilt thou seek truth during the night, and thy soul will have been hungry.
