In case it is at all unclear, I would like to take a second to, once again, thank the majority of posters in this thread for their clear, rational, non-acrimonious postings.
Even though some particular post may not have swayed my particular opinion, I (for one) do appreciate the well-thought-out objections to my opinion. I don't believe that there is anything incongruous with holding an opinion, and simultaneously being willing to accept that your opinion may not be correct.
There is a difference between stating "This is what I believe" and "This is what I believe, and I also believe I cannot be wrong in that belief." I should think that obvious, but I realize that there are some few for whom it is not.
Let me use a couple of semi-absurd examples that I hope will illustrate my point:
Let us say that I have never seen a shade of green that did not utterly disgust me. I would then, naturally, hold the opinion that all shades of green are disgusting to me. I would hold that opinion very strongly. Were you to say, "I have a shade of green you will love", I would be unlikely to accept it is true without strong evidence, and, depending upon the effort required to actually obtain that evidence, I might dismiss the claim outright as being highly unlikely.
But I could be wrong. There could be a shade of green out there so dazzling to my eyes that, not only do I love it, but I find that I can now tolerate (or even enjoy) other shades of green through my appreciation of that particular shade.
Another clear example is the smoking example. I have a great deal of second-hand evidence that suggests smoking is harmful, and a reasonable amount of first-hand evidence that suggests the same. It is, therefore, likely that I will conclude that smoking is harmful. Now, it may also be true that my grandfather smoked, and lived with good health until his late 80s. It may be true that your grandmother smokes, is 127, and is still going strong. But neither of these isolated statements is likely to make me believe that smoking is not harmful, and that they could not have lived longer/be healthier without it.
But, again, I could be wrong. It is entirely possible that the anti-smoking lobby, for whatever reason, has doctored the evidence, intentionally or not, to fit their bias. My first-hand experiences could be coincidental.
But I would be foolish, in either the green or smoking example, to assume that I was wrong, or even assume that it was reasonably likely that I was wrong.
Anyway, I again wanted to offer a real heart-felt thank you to the majority of posters. Even where I disagree with you, I appreciate the additional material/arguments to ponder. Rational arguments are something that can be considered, answered, accepted, or rejected. Even where arguments are ultimately rejected, the consideration of them allows for real growth.
I have said it before in this thread, and I will say it again: Simply because I argue/believe one way, it shouldn't make anyone change what they are doing unless they find the argument compelling and not incongruous with his or her experience. Otherwise, the guy on the ground floor who argues that the window is a perfectly fine way to leave a house is going to lead a lot of people on the 10th floor astray. Especially if that guy has said, again and again, that he has never seen a house with more than one floor, and isn't at all certain that they exist.
And to those people who are on the other side, have provided stimulating posts again and again, and haven't taken offense that I haven't agreed with them, a special thanks. It is people like you that make EN World great!
(And, on this thread, that's quite a few people)
