There is no short-cut no patent tram-road, to wisdom. After all the centuries of invention, the soul's path lies through the thorny wilderness which must still be trodden in solitude, with bleeding feet, with sobs for help, as it was trodden by them of old time.
. . . for the growing good of the world is partly dependent on unhistoric acts; and that things are not so ill with you and me as they might have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited tombs.
George Eliot (1819 - 1880)
