No mistake is more to be deplored than the conception that a system of morals and religion should derive any portion of its authority either from the circumstance of its novelty or its antiquity, that it should be judged excellent, not because it is reasonable or true, but because no person has ever thought of it before, or because it has been thought of from the beginning of time.
Percy Bysshe ShelleyWe rest; a dream has power to poison sleep. We rise; one wand'ring thought pollutes the day. We feel, conceive, or reason; laugh or weep, Embrace fond woe, or cast our cares away; It is the same: for, be it joy or sorrow, The path of its departure still is free. Man's yesterday may ne'er be like his morrow; Nought may endure but Mutability!
Percy Bysshe ShelleyWhen you can discover where the fresh colors of the faded flower abide, or the music of the broken lyre, seek life among the dead. Such are the anxious and fearful contemplations of the common observer, though the popular religion often prevents him from confessing them even to himself.
Percy Bysshe ShelleyIf all the thought which had been expended on the construction of engines of agony and death - the modes of aggression and defence, the raising of armies, and the acquirement of those arts of tyranny and falsehood without which mixed multitudes could neither be led nor governed - had been employed to promote the true welfare and extend the real empire of man, how different would have been the present situation of human society!
