In her essay, “The Other Six Deadly Sins,” (collected in Creed or Chaos) Dorothy Sayers writes:
There are two main reasons for which people fall into the sin of Luxuria [lust]. It may be through sheer exuberance of animal spirits: in which case a sharp application of the curb may be all that is needed to bring the body into subjection and remind it of its proper place in the scheme of man’s twofold nature. Or—and this commonly happens in periods of disillusionment like our own, when philosophies are bankrupt and life appears without hope—men and women may turn to lust in sheer boredom and discontent, trying to find in it some stimulus which is not provided by the drab discomfort of their mental and physical surroundings. When that is the case, stern rebukes and restrictions are worse than useless. It is as though one were to endeavour to cure anaemia by bleeding; it only reduces further an already impoverished vitality. The mournful and medical aspect of twentieth-century pornography and promiscuity strongly suggests that we have reached one of these periods of spiritual depression, where people go to bed because they have nothing better to do. In other words, the “regrettable moral laxity” of which respectable people complain may have its root cause not in Luxuria at all, but in some other of the sins of society, and may automatically begin to cure itself when that root cause is removed.
