It is my experience that you understand a thing thoroughly only when you can state, simply and compellingly, the fundamental idea on which all else depends. Here are some things I know.
First Law: Everyone believes their own bullshit.
Second Law: The truth is made up.
The Framing Dilemma (Corollary to the Second Law): A picture is worth a thousand lies.Third Law: Every road leads to the end of the road.
Fourth Law: Most problems are caused by solutions.
Fifth Law: The Devil works both sides.
The Thermodynamic Conundrum: Uselessness always increases.
