我自己的感觉是，现代世界很难获得自我知识。越来越多的人生活在广阔的城市环境中，被其他人类和人类的创造所包围。自然世界是传统的自我意识来源，越来越没有。
(My own sense is that the acquisition of self knowledge has been made difficult by the modern world. More and more human beings live in vast urban environments, surrounded by other human beings and the creations of human beings. The natural world, the traditional source of self-awareness, is increasingly absent.)
