I've never read CS Lewis, but I understand he was a Christian philosopher.

But you have to keep in mind, even though he may have been a wise man, and have much of value to contribute, he has exactly the same knowledge of the universe that you do. No more, no less. Only his interpretation and perspective is different.

I was really impressed with Alan Watts when I read him as a young man. Watts was a leading authority on Zen Buddhism, although he was also an Episcopal priest.

Remember, we all see different universes around us, but they are really all the same universe. We simply see them through different filters, and interpret them in different ways, using different metaphors.

And remember, there is no Truth, except for trivial things like mathematical expressions of physical law. None of those things make any real emotional or spiritual difference to us, unless we're designing circuits or undertaking some other purely mechanical operation. When it comes to what's going on in our heads, or the heads of those around us, or our communities, or history, we're all on our own. Mr Lewis or Mr Watts may have something to teach is, but we can't really count on it.
