Intelligence is usually a measure of how fast or slow it takes someone to grasp a theory or idea. In the case of religion, however, there is so much anxiety that people are inhibited from thinking intelligently. They have blinds spots. I have invented an intelligence test for religion: What are four solutions to the mind-body problem and four answers to the question of what caused the universe to begin 13 billion years ago? I give myself an IQ of 100. I get 20 points for understanding the mind-body problem and 10 points each for the eight answers. Thomas Nagel has an IQ of 50.
Nagel understands the mind-body problem (20 points), but he only grasps three solutions: dualism, materialism, and idealism (30 points). He doesn’t understand the insight that the mind-body problem is a mystery and humans are embodied spirits, unless by "monism" he means humans are embodied spirits:
Among the traditional candidates for comprehensive understanding of the relation of mind to the physical world, I believe the weight of evidence favors some from of neutral monism over the traditional alternatives of materialism, idealism, and dualism. (location 69 of 1831)
The four answers to what caused the big bang are 1) God did it. 2) An angel did it. 3) The universe is not intelligible. 4) The scientific method will eventually give us an answer. There is no evidence for # 1, but more for # 2 since an angel would have a motive for doing such a thing. The answer judged to be true by rational people is # 4. Nagel gets no credit because he doesn’t know the difference between an angel and God. A stopped clock is right two times a day.
