I’ve thought this for a long time about Math.

Math (and science, to a degree) is perfect. It is a universe with perfect lines.

It is NOT real. It is completely manufactured. It is completely defined. Nothing that math can do is without meaning.

and that’s because it was invented.

My PMP stuff is the same. It is a universe of perfectly defined terms. The books constantly says, “You may THINK you know, but you don’t know until we say you know.”

It is a world of defined terms…words that, in fact, may have a meaning competely different outside itself, but a meaning which must be abandoned at the door.

Because anything that doesn’t match it is rejected.
