Whatever humans have learned had to be learned as a consequence only of trial and error experience. Humans have learned only through mistakes.
R. Buckminster FullerYou do not belong to you. You belong to the universe. The significance of you will remain forever obscure to you, but you may assume you are fulfilling your significance if you apply yourself to converting all you experience to highest advantage to others. Make the world work, for 100% of humanity, in the shortest possible time, through spontaneous cooperation, without ecological offense or the disadvantage of anyone.
R. Buckminster FullerEvery time man makes a new experiment he always learns more. He cannot learn less.
