Not a belief. Not an authority. A fact: right now, you are having an experience. Try to deny it — the denial is itself an experience.

From that single point, with nothing assumed and nothing imported, the argument moves one verifiable step at a time. Experience is always of something. It has a here and a there. It moves through time. Each moment leans on the one before it.

You don't have to take any of this on my word. You can walk the first seven steps yourself — right now, in about five minutes.
