"What makes the difference between objectification and non-objectification
is the presence or absence of LOF."
Isn't that amazing? Okay, to back up and give you the context and meaning for "LOF" Catholic philosopher Colleen McCluskey's essay, Lust and Chastity is located within this thick book, Virtues and Their Vices. The book has a number of essays from Christian thinkers engaging this topic. If you are a geek and you are interested in philosophical scholarship that tackles virtues and vices, this book is for you.
I wanted to highlight for you this one thought from Colleen McCluskey in her chapter on lust and chastity. In this essay, she brings together chastity as proposed by Thomas Aquinas, and lust, proposed by Simon Blackburn in his book titled simply, Lust. She particularly explores Aquinas' views of chastity as it pertains to sex within marriage. Aquinas heavily favored the idea that sex was for procreation, not for pleasure. Aquinas, according to McCluskey, lust was an inappropriate desire for the pleasures of sex.
