Men are fools. We cannot talk to them with our language, neither can we make them understand. Had we answered their questions, they would tell us that it was not the answers they were looking for. Had we given them the proofs, they would demand more proofs. Had we revealed all to them, they would collapse in that instance before they could even understand one tenth of what we were about to reveal. So we made the wise among them spoke in their tongue [the language of fools], guide the many of them who were lost, and through the wise we revealed the truths gradually. One at a time.
