In Book III, which deals with morals, I have also passed over some things but for a different reason. Ever since I served as an infantryman in the First World War, I have had a great dislike of people who, themselves in ease and safety, issue exhortations to men in the front line. As a result I have a reluctance to say much about temptations to which I myself am not exposed. No man, I suppose, is tempted to every sin...I have...said nothing about birth control. I am not a woman or even a married man, nor am I a priest. I did not think it my place to take a firm line about pains, dangers and expenses from which I am protected; having no pastoral office which obliged me to do so.
