Inner Courage
And whereas men's courage will be tremendously increased by outer culture, air vehicles and other technological attainments, at the same time life will be considered to be of little value. Men will be overcome by deep sadness and melancholy, and the number of suicides will rise sharply. While outer courage is growing in sensory life, inner courage will necessarily decline and give way to a disguised cowardice. Men become ever more materialistic and don't want to know anything about the soul and spirit. Angels inspired Kant to set up his limits to knowledge, so that men could develop outer courage. But just as a compressed rubber ball springs back, so this will produce a reaction in souls, and then men's courage will want to turn to the attainment of knowledge of spiritual worlds again. -Rudolf Steiner
