This is a big enough deal that I'd like to give it its own post.
Information gets from the real world into our brains through the senses. We observe. Is there really any doubt about this?
For Christians, is the information about God simply beamed directly into your brain by God himself? If so, why is there a Bible that requires you to use your senses to read it?
Can we finally agree once and for all that we can obtain no information about the real world except through observation?
