A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and of many others; the pains and pleasures of his species must become his own.
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 ShelleyThe great secret of morals is love; or a going out of our nature, and an identification of ourselves with the beautiful which exists in thought, action, or person, not our own. A man, to be greatly good, must imagine intensely and comprehensively; he must put himself in the place of another and of many others; the pains and pleasure of his species must become his own. The great instrument of moral good is the imagination.
