As a cardinal value of Jewish ethics, humility may be the best antidote to heresy hunting. “Heretics” have often been proved right. If the heresy hunter argues a point of disputed fact — say, regarding the authorship of a particular biblical text — he or she may ultimately be wrong. No amount of intimidation can change what is true to false. On the other hand, of course, the “heretic” may be wrong. For that reason, even the most ungenerous among us should consider such a person mistaken, rather than disloyal to his community.
