Perhaps the greatest of the many fundamental changes which are inevitable for the man who studies the facts of life is that which is produced in his attitude towards death. This matter has been fully treated elsewhere; here I need state only that the knowledge of the truth about death robs it of all its terror and much of its sorrow, and enables us to see it in its true proportion and to understand its place in the scheme of our evolution. It is perfectly possible to learn to know about all these things instead of accepting beliefs blindly at second-hand, as most people do; and knowledge means power, security and happiness.
