I was posed a question the other day by a friend who stated: Can you think of anything that is immaterial that you can show exists?
I thought about it for a few minutes and came up with a few answers. I said that consciousness, the laws of logic and information would all answer his question.
He decided to focus on information, and asked for a more in-depth answer. I told him that information isn't bound by space-time limitations and through different quantum mechanical tests it can cause different outcomes simply by being known. He was highly unsatisfied with this answer, and said he still didn’t believe me.
He then rephrased the question to a statement: Give me a thought experiment that demonstrates types of information that exist without a physical medium.
First I’d like to get everyone’s views on if I am correct in the first place with my assessment that consciousness, the laws of logic and information are truly immaterial. Second, I need some help trying to come up with an answer to his statement . Any help would be appreciated as I’m lost for a rational explanation.
