All ages have said and repeated that one should strive to know one's self. This is a strange demand which no one up to now has measured up to and, strictly considered, no one should. With all their study and effort, people are directed to what is outside, to the world about them, and they are kept busy coming to know this and to master it to the extent that their purposes require. . . . How can you come to know yourself? Never by thinking, always by doing. Try to do your duty, and you'll know right away what you amount to. And what is your duty? Whatever the day calls for.
Johann Wolfgang von GoetheLet everyone sweep in front of his own door, and the whole world will be clean.
Johann Wolfgang von GoetheMust it ever be thus-that the source of our happiness must also be the fountain of our misery? The full and ardent sentiment which animated my heart with the love of nature, overwhelming me with a torrent of delight, and which brought all paradise before me, has now become an insupportable torment, a demon which perpetually pursues and harrasses me.
Johann Wolfgang von Goethe
