Revery, which is thought in its nebulous state, borders closely upon the land of sleep, by which it is bounded as by a natural frontier.
Victor HugoSuperstitions, bigotries, hypocrisies, prejudices, these phantoms, phantoms though they be, cling to life; they have teeth and nails in their shadowy substance, and we must grapple with them individually and make war on them without truce; for it is one of humanity's inevitabilities to be condemned to eternal struggle with phantoms.
Victor Hugo
