"In calm retrospect we can appreciate better the disastrous effects of the poison of falsehood, whether officially, semi-officially, or privately manufactured. It has been rightly said that the injection of the poison of hatred into men's minds by means of falsehood is a greater evil in war-time than the actual loss of life. The defilement of the human soul is worse than the destruction of the human body. A fuller realization of this is essential."
