The man who is fit to handle pig iron is not fit to handle the management of pig iron.
——1945年4月接到希特勒已死的消息时说
Every seed we plant today is a promise to future generations.
没有完美的知识可以称为我们与生俱来的；唯有从经验中获得的知识才是真正的知识。
The essence of modernity is psychologism, the experiencing and interpretation of the world in terms of the reactions of our inner life and indeed as an inner world, the dissolution of fixed contents in the fluid element of the soul, from which all that is substantive is filtered and whose forms are merely forms of motion.
世界是一面镜子，反映出我们带给它的东西。
