A reader writes:
Sam Harris' critique was anticipated, and dealt with, by Paul almost 2000 yrs ago:
"For we preach Christ crucified, a stumbling block to Jews, and foolishness to Greeks, but to those who are called, both Jews and Greeks, Christ the power and wisdom of God."
This doesn't mean Paul ignores Sam Harris, for whom the gospel is plainly "foolishness." Far from it. He went to the Areopagus in Athens and debated with the philosophers all day. And Acts very interestingly records the simple fact that upon hearing Paul, some thought he was foolish, others wanted to hear more, and some became believers and their lives were changed. Christians will do the same: debate with all, and know that some will find us to be fools, while others will find the miracle of faith.
