Are these not reflected in your comment?

For unrelated reasons (looking up the author of a quote in the bsd fortune file) I was looking at François de La Rochefoucauld's wikipedia page and learned that he wrote this in the intro for his book of maxims on human behavior:

"... the best approach for the reader to take would be to put in his mind right from the start that none of these maxims apply to himself in particular, and that he is the sole exception, even though they appear to be generalities. After that I guarantee that he will be the first to endorse them and he will believe that they do credit to the human spirit."
