Okay. Not to belabor a point, but some examples of what you are talking about would be helpful, if you are suggesting that philosophy would help us be better thinkers. I'm always trying to help people be better thinkers, which is why your statement interested me.
I think it's the highest goal because it's like the rising tide example - where better reasoning uplifts all other goals somebody might have.
Pascale's Wager is fatally flawed. Thats the easiest example to grasp.
Lots of C.S. Lewis' literature is fallacious as he appeals to claims of normativity to make the wider cases he's making, and most of the normativity he's implying is either demonstrably false, or yet to be established.
In other words, in order to prove his overarching claims, he just makes more undemonstrated claims. That's the fatal flaw in most of his literature. Its the type of a lack of discipline I was referencing before.
The good news is that many folks possess the ability to reason properly.
