I can't reasonably predict the weather next week. But either way, I don't choose what to do based on what some Ph.D. will think of it 40 years from now, I choose what to do based on whether it's right or wrong. When it's not that simple, I try to go by what is the best overall solution.
I can see how the way I phrased it brings up the eyes of some Ph.D., but I was thinking more about having a complete picture of things, or new information changing the context of interpretation for things, etc.
Well, I always reserve the right to change my mind when the facts change, or my understanding of them does. I don't like to think I'm locked into a certain viewpoint or worse, that my viewpoint changes to be what's most advantageous for me personally at any given phase in my life. And I do think I have a good understanding of history.
But at the same time I think that a good understanding of history's past failures can enable you to essentially "try again correctly" in the future.
I think all of us agree that civil liberties are important and that a government's protection of its citizens is important. I see it as an area of tension, but not as a bloodfight like some on both sides of that issue.
(I'm thinking that lots of things that seem normal now might not seem so reasonable in 30 years)
