Frank Wilson passes on this thought from Joe Orton: “The kind of people who always go on about whether a thing is in good taste invariably have very bad taste.”
This sounds right, but it also sounds like the response of someone who has been thoroughly criticized.
Along the lines of good and bad taste, I stumbled across a series of videos by Roger Scruton on beauty. http://www.raysawhill.com/blog/2009/12/30/roger-scruton-on-beauty.html
