The political press is chortling at BuzzFeed’s story that Ben Carson believes Egypt’s pyramids were built for grain storage, not as burial chambers. “My own personal theory is that Joseph built the pyramids to store grain,” he said in a 1998 commencement speech, referring to Genesis 41, which tells of Joseph storing Egypt’s grain during the “years of plenty” for the coming famine. Carson confirmed to CBS yesterday that he still believes this, but I’m not sure why this is such a big story. Before Wednesday, we knew that Ben Carson takes the Bible literally. After Wednesday, we knew the exact same thing. Frankly, I don’t care whether the president believes the pyramids were built by Joseph, aliens or the Egyptians themselves levitating the stones into place. What matters are the ideas — and that’s where the focus should be with Carson, since it’s clear he has no idea what he’s talking about.
