M2: Everything is true.
GP: Even false things?
M2: Even false things are true.
GP: How can that be?
M2: I don't know man, I didn't do it.
M2: Indeed! But do not reject these teaching as false because I am crazy. The reason that I am crazy is because they are true.
M2: Something inside my brain said that, so it must be true.
I'm surprised wikipedia doesn't have that theory.
The trivium was rhetoric, grammar, and logic - the basic tools of reasoning and argument. It formed a basis for further study; the quadrivium relied on knowledge of the trivium, and consisted of astronomy, geometry, arithmetic and music.
The trivium was "trivial" because it was "Knowledge 101" - a foundation course, as it were.
A proposition is trivially true if it can be seen to be true merely by inspecting the proposition, and without reference to real-world facts. If all statements are true by definition, you don't even need to inspect them. So I guess "trivialism" is the position that all statements are trivially true.
