" This experiment may fail, but if it succeeds it can be the most important event of our time--even more important and consequential than this war we have just fought. (...) I had a wife and three children, and they were put to death because a nation of men turned into beasts. I watched that, and I could not have lived through it unless I believed, always, that what can turn into a beast can also turn into a man. We are neither. But if we go to create man, we must be humble. We are the tool, not the craftsman, and if we succeed, we will be less than the result of our work. "
