We clutter the earth with our inventions, never dreaming that possibly they are unnecessary - or disadvantageous. We devise astounding means of communication, but do we communicate with one another? We move our bodies to and fro at incredible speeds, but do we really leave the spot we started from? […] What have we achieved in mowing down mountain ranges, harnessing the energy of mighty rivers, or moving whole populations about like chess pieces, if we ourselves remain the same restless, miserable, frustrated creatures we were before? To call such activity progress is utter delusion.
