This is the more approachable, theological (as opposed to philosophical) brother to The Abolition of Man. Very cleverly written, thoughtful, and worth the read. But me telling you about it is no fun, so let me just give you some illustrative quotes instead.
“If you look for truth, you may find comfort in the end: if you look for comfort, you will not get either comfort or truth–only soft soap and wishful thinking to begin with and, in the end, despair.” 32
“I feel a strong desire to tell you—and I expect you feel a strong desire to tell me–which of these two errors is the worse. That is the devil getting at us.” 186
“Good people know about both good and evil: bad people do not know about either.” 93
“Much as you admire your husband, would you not say that his chief failing is his tendency not to stick up for his rights and yours against the neighbors as vigorously as you would like? A bit of an Appeaser?” 114
