A-G, I'm sure that is the case with many people who object to the suggestion that there is anything at all immaterial about our Universe. But it seems to me the objection just doesn't hold up.
I mean, think about it: Matter is universal, ubiquitous, and homogeneous, generally speaking. Everything in the world is made out of the same "stuff," to put it very crudely. It seems to me that what makes an entity the thing it is, given the ubiquity and "sameness" of matter, is how the matter is put together, how it is assembled -- its "instruction set." But now we are talking about an entity's information content -- and this is not a material thing.
Just a little speculation I've been thinking through lately....
Thanks so much for writing, A-G. Hugs!
