Reply? To which part? I have trouble just following you sometimes.

I never said the process of discovering the answers is simple. Nor would any real scientist be stupid enough to claim certainty that he had found the final and absolute truth at the end of a quest. Still, when you find out how the universe and humanity works at a basic level, the answers you do find are often simple ones.

Many religions have cooked the rules for human interaction down to the Golden Rule. And it often works. But this kind of thinking wouldn't employ many clerics.

Ayn Rand, as part of a challenge, once explained her basic philosophy while standing on one leg. I'd like to see some of the other philosophers try that.

"There Ain't No Such Thing As A Free Lunch" covers a lot of economics. "No man should be another man's property" covers most of the rest.

You make a very good point--assuming I got it right--that the obvious answer is not always the true one. Occam sometimes falls flat on his face. Then again, nothing says that a simple truth has to be obvious, or they wouldn't be so hard to find sometimes.

But you know what? In the real world, sometimes the obvious answer is close enough, even if it isn't the truth.

To add to your example of the Solar System, look at the idea that the Earth is round. Throughout history, probably 99 percent of people operated on the basis that the Earth was flat, and within their own realm (the local village, the farm, the city, the other town three days travel away) the model served perfectly well. Only in certain fields, like ocean navigation and others, did the model need serious work. Sherlock Holmes knew nothing of Copernican astronomy, and was proud of it. It didn't matter in his field of work.

Hey, in your everyday life, is there a single thing you do that you would do differently if the Earth actually were flat? Closest thing I could think of was I wouldn't have to change my watch when I flew to the Midwest.

In the same way, real-world (engineering) physics is usually handled as though Einstein never existed, and only Newton matters.

Frankly, as long as people are left to do their jobs, raise their families, and are protected from the really bad stuff, most folks could care less about politics, philosophy, and the Deep Questions. Experience and common sense are usually enough, if nothing rocks the boat. It's when the boat gets rocked, or the ship doesn't fall off the edge of the Earth, that you have to really start working on the premises.
