These things are known to be real by sheer common sense; the fact that materialism rejects them as the effects of solely physical processes seriously undercuts the ideology’s ability to make sense of the world.

There was a time when the newspapers said that only twelve men understood the theory of relativity. I do not believe there ever was such a time. There might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper, a lot of people understood the theory of relativity in some way or other, certainly more than twelve. On the other hand, I think I can safely say that nobody understands quantum mechanics.
