Certainly, I didn't mean to go so far as to say what we can see and touch might not be real. As far as I'm concerned, that's covered in the "common observances"

Certainly, I didn't mean to go so far as to say what we can see and touch might not be real. As far as I'm concerned, that's covered in the "common observances" I mentioned in my previous comment. The "truths" I was referring to are things we can't verify ourselves (due to practicality or lack of knowledge), yet are commonly believed or taken for granted. Some examples: - World maps - Authorship (of music, books, etc.) - Photos (see #bowwowchallenge for a good laugh) - News - The immutability of physics :)
