Take the issue of aesthetics. We all know that matters of taste are different from matters of fact—that standards of right and wrong apply to facts but not to preferences. Indeed, we are somehow able to sort this out very early in life. Even young children understand that it’s not okay if you think the sky is blue and I think the sky is green, but totally okay if your favorite color is blue and my favorite color is green. Yet it is comically easy to find examples of full-grown adults acting like their own taste is the gospel truth.
