O'Toole's Commentary:

"Murphy was an optimist."

I'd say some of his observations sound pessimistic (sometimes even wierd); but they are surprisingly realistic.

Here's probably all the Murphyisms you could ever want or need

I apologize. Perhaps the spacing I used made it difficult to recognize the context I was giving.

The phrase 'Murphy was an optimist' is the 'law' called O'Toole's Commentary. As you yourself pointed out, the hypothetical original Murphy would seem to have been somewhat, if not severely, pessimistic. So how pessimistic must O'Toole's outlook have been?

How 'bout the 3 laws of thermodynamics re-phrased:
1) You can't win
2) You can't break even
3) You can't get out of the game.

Murphy fought entropy and entropy won

I guess that would be pessmistic beyond the realms of reality.

Capitalism is based on the false assumption you can win (but government prevents that)

Socialism is based on the false assumption that you can break even.

Mysticism and Transcendental Meditation are based on the false assumption that you can quit the game.
