In MR's case, I think that he likes feeling that reality isn't all safely categorized in little boxes (even if they are scientific), that it still contains things that are amazing, unexpected and wondrous. To him, ufos and ghosts and whatever suggest that the universe exceeds and transcends the conventional conceptual categories, suggesting that our current understanding isn't the last word on everything. It's why other people embrace religion. (MR has the strongest sense of the miraculous of any atheist I've ever met.)
And I think that MR does like poking sacred cows with a stick. It isn't "animus against science". (Since when is disbelief in ufos 'science'?) It's because some of the people around here seem to him to be as doctrinaire as Biblical fundies. (I feel much the same way. One naturally wants to pop the smug self-satisfied balloons.)
As for me, I have mixed emotions. I think that many of the things that MR promotes aren't particularly credible. But I sympathize very strongly with what I take to be his motivation. It's just that I think that he's looking in the wrong place. I find my own sense of mystery in contemplating philosophical problems.
One of the things I dislike about Sciforums is the way that it's populated by people who go on and on about "evidence", "reason" and "reality", about the science/pseudoscience distinction, and about how everyone needs to employ the "scientific method" -- while seemingly having no feeling at all for the deep and difficult questions that all of those topics raise.
Whenever I think about science, I'm confronted by an almost endless succession of philosophical questions: The atheism/theism discussions. The assumptions of physicalism, whether methodological or metaphysical. The nature of evidence and how evidence is used to confirm hypotheses. Understanding deductive inference. What is truth? What does it mean to explain something? Problems of scientific methodology. Are there limits on what humans can know? Is anything absolutely certain? What are necessity and possibility? Does every event have a cause? What is the place of purpose and free-will in a physical universe? What is 'consciousness'? What are phenomenal properties like 'red'? What is meaning and how do words acquire it? What kind of reality do abstract objects like numbers have and how do we know about them? Is our knowledge of the physical world based solely on sense-perception? Can qualitatively new kinds of phenomena 'emerge' unexpectedly from complex systems? What is 'life'? What different kinds of life might there potentially be? What does quantum mechanics tell us about the nature of physical reality? What is the relationship between scientific theory and the reality it models? How do scientific theories change as science progresses?
And on and on... The questions are never ending. If we think about even the most familiar aspects of our lives for more than a minute or two, we are suddenly at the frontiers of human knowledge. We are surrounded by the unknown at every moment. It's the intellectual air we breathe.
It doesn't require a journey to CERN or to an astronomical observatory to approach the mysteries. It doesn't require scripture or a visit to a soaring cathedral. It doesn't take MR's ufo incursions or ghost hauntings.
It just takes a little thought.
Nice post: In many respects I agree....I'm sure the universe is even more amazing, unexpected and wondrous then we can imagine, but as yet we still do not have the extraordinary evidence available to validate the existence of ETL, as much as I would dearly love for that to be evident before I kick the bucket.
I'm also not sure why you expect a forum that is first and foremost a science forum, to not apply scientific scrutiny to all claims, even those in the supernatural/paranormal/ghosts/UFO sections.
Life imvho most certainly exists off this Earth, but the facts remain as facts: and that is as of this time, we have no convincing or extraordinary evidence to validate that position, other then the indirect evidence of near infinite extent and content of the universe, and the stuff of life being everywhere we look.
You ask what is the relationship between scientific theory and the reality it models? and how do scientific theories change as science progresses?
My take on that is that scientists model as best as they can, what we observe and aligning with the results of those experiments: The reality is not the prime objective, but if they happen to hit on that reality, all well and good.
And obviously theories are changed, modified and improved as our observations are extended and improved, and as our technological abilities are enhanced.
And while it certainly does not require a journey to CERN or to an astronomical observatory to approach the mysteries of the universe that surrounds us, to write off such state of the art technology is plainly stupid.
I once while laying back on an isolated beach in Fiji, with my simple pair of 7x50's, saw the three of the four Galilean Satellites orbiting Jupiter: A defining moment in my life, which thrilled me to bits!
And again to repeat myself, I have also seen a UFO, and to this day that's what it remains.
The undeniable facts, that seem to upset MR whenever they are put to him, are never the less, legitimate facts.
I'm speaking of the many other explanations that could be seen to apply to any of his highlighted situations...delusions and illusions [people do suffer from them] Atmospheric disturbances and anomalies that also certainly take place, mirages being one, trickery and games by others looking for a weird sense of fun. These all can possibly be applied.
Could ETI have visited Earth? Certainly it could have: but as yet no extraordinary evidence of any such visitation is available.
In concluding, MR seems to want immunity to any scientific scrutiny applied to his beliefs: Other times, he denies he is stating anything as fact, but simply putting it out there for all to see, but then strangely, rejecting all other possible reasons for that scenario.
Then we have of course the extremism of river and his claims of a nuclear war on Mars and the sinister overtones of the supposed face on Mars, because, wait for it! He read it in a book!
What MR claims re UFO's and some of the reported sightings, may very well be true, but equally, they maybe false and simply innocent or willful fabrication in peoples minds for the reasons I have previously given.
