“I find it difficult to excite myself very much over right and wrong in practice. I have, e.g., no clear idea of what people have in mind when they say that they labour under a sense of sin; . . . A healthy appetite for righteousness, kept in due control by good manners, is an excellent thing; but to ‘hunger and thirst after’ it is often merely a symptom of spiritual diabetes.”--C.D. Broad, Five Types of Ethical Theory (1930), paperback edition (Littlefield, Adams, 1959), p. 2.
