CHAPTER III
HYGIENIC SEQUENCE IN DEVELOPMENT
As I shall have to speak of artificial as contrasted with natural movements, of tools (physical and intellectual) which it is natural to use as contrasted with those the use of which is artificial, I must begin by explaining that I entirely recognize the principle 'habit is second nature.'
