Rowan --
I wish I could reply with something other than a knowing "yep," but I think there's no way to do that! Interestingly, I just looked up "politics" in the dictionary and was intrigued that it is defined as the art *or* science of government. As an investor who has had occasion to wonder which of the two I practice, It's rather refreshing to learn I'm not alone.
As an aside, it's somewhat disheartening to find that "investing" is defined primarily in the medieval sense.

Cheers, all best, and thanks for prompting my wonderings!
