It has been justly observed, that discord generally operates in little things; it is inflamed to its utmost vehemence by contrariety of taste, oftener than of principles
--Johnson, Rambler 99
I had a girlfriend once who liked her eggs scrambled hard. I liked mine scrambled loose. Instead of saying that we liked our eggs cooked differently, she insisted that she scrambled eggs correctly; I scrambled them wrong. From this I derived the Scrambled Egg Principle: Do not elevate differences of taste into differences of principle. I see that, as usual, Johnson has anticipated me.
