Abstract

There are things we should do, and other things we should not. Some choices are ­permitted, others are required, and others are impermissible. Some behavior is appropriate, some feelings unwarranted. Happiness is good. Nazis are bad. Italian fascists are also bad, but Nazis are worse. Some think eating meat is immoral; others, that mentioning such beliefs in the presence of the Thanksgiving turkey is impolite. Double-parking is illegal; so is murder, even murder of a Nazi.
