Thanks, Nick, you describe an interesting way of establishing a life-view. Not quite sure how to answer, except to say that if I have faith in anything, it is in evidence. If I have accrued a sufficient pile of evidence that supports a conclusion about some observation, then I'll probably believe it.
If my collected evidence is such that the inescapable conclusion is that nothing is constant, then I suppose I'd eventually come around to believe that, so long as I had a constant framework from which to corroborate and verify the inconsistencies. Otherwise, I'd continue to look for the missing pieces of the puzzle (a reference to the cosmological artifacts I sent you earlier). As to religion: for me it's a big "No thank you" to any cult mindthink that requires brainless acceptance of a supernatural homo-centric benevolent/malevolent boogyman. And that goes double for one particular cult whose belief system is predicated upon "hieroglyph"-inscribed disappearing golden tablets. Oh, and I guess that goes triple for any cult that attempts to dictate what kind of skivies I must wear to become a member of the club. I guess you could say that it would take a *miracle* to get me to assent to becoming a member of any of the existing flocks of theist-following sheep out there. In retrospect, I suppose I do have faith in one other fairly immutable quality -- the accuracy of my bullshit detector. --Doug On Tue, Mar 27, 2012 at 11:47 AM, Nicholas Thompson < nickthomp...@earthlink.net> wrote: > Dear Doug, **** > > ** ** > > I am afraid that the black hole example is already too technologically > dense for me, so I am going to punt on the project of luring you inside my > walls and slaughtering you there, and just out-right tell you what I think > **** > > . **** > > The argument began with my detecting in you (perhaps wrongly) the belief > that you, unlike the religious, can get along without some sort of faith in > your life.
