 Loving people requires loving all people without exception, only then is this called loving people. Not loving people does not require loving no people at all; it is (rather) not loving all people without exception, and by this it is called not loving people. Riding horses does not require riding all horses without exception; it is (rather) riding some horses, and by this it is called riding horses. But not riding horses does require riding no horses at all; only by this is it called not riding horses. These are cases in which something applies without exception in one case but not in the other. (Xiao Qu; tr. Graham 2003 [1978])
