Our present troubles are not due to Nature. They are entirely artificial, genuinely horne-made. The very arts and sciences which we have used to conquer Nature have turned on their creators and are now conquering us. The present crisis is of our own making; we have brought it on ourselves by allowing our mechanical and agricultural science to develop more rapidly than our economic science. We cannot buy \vhat we produce and are therefore compelled to keep our factories idle and let our fields lie fallow. Millions are hungry, but wheat has to be thrown into the sea. This is where, at the moment, science has brought us.
