Here’s a zinger in the sense that you can tell somebody that we know more now than Jesus did or the writers of the Christian bible:

“I don’t think that we can go back at all, either to the secularism of Odysseus or to the days of Mohammed or to the days of Christ or the days of Abraham. We know much more than any of these prophets and heroes and visionaries knew. We have accumulated more experience than they had. We are not closer to any universal truth than they are. We are not closer to anything transcendent than they were. We are simply more experienced, more able to see what will cause harm and what might do good. So I don’t think that it’s a question of returning, it’s a question of constantly attempting to make the future still more different from the past.”
