AB,
The jig saw is a good analogy.
I know, but not in the way you think it is.
Human scientific investigation…
What other kind is there? Anyway…
... has provided some of the pieces (which I do not deny or contradict),
Yes you do – about evolutionary theory for example.
…but in all honesty we do not know what is missing or how much is missing from the complete picture.
Yes I know. That’s why people called scientists keep doing science - to find more of the missing pieces.
We have both attempted to fill in the missing pieces.
You haven’t. You’ve just thrown up your hands, said it’s all “beyond human understanding” and walked away. Your stance is essentially regressive – living in fearful ignorance by asserting “it’s all god’s will” or some such is the abnegation of learning and progress. It’s precisely because some people haven’t settled for that non-answer and instead have investigated, tested and invented that we have the fruits of scientific endeavour now.
In your case, you have filled in pieces…
Not “you” – reason and science and honest engagement with the evidence but ok…
which give a very different picture from what we actually perceive to be our reality,
Yes. Cogent reasoning and hard evidence tend to do that in many cases. That’s because evolution has no remit to enable us to intuit an objective reality just by living in it – rather it’s given us abilities that best confer survival advantages, but no more. “What we actually perceive to be our reality” is in other words only that – a perception – whereas a more rigorous approach tells us that our perceptions are often wrong at an explanatory level.
…but you seem to insist that your attempt to fill in the missing pieces offers a truer picture than what we perceive.
Again, not “your” – reason and evidence and science do that, and absolutely yes. “What we perceive” is a highly unreliable, subjective, essentially arbitrary way to understand reality. That’s where you keep going wrong remember? “Free will feels free to me, therefore it is free” is epistemically worthless whichever way you look at it.
…but I have more faith in our own perception of reality,…
Yes, we know you have “faith”. The problem is, that’s all you have – and your faith beliefs are often demonstrably wrong too.
…and have attempted to fill in pieces which can offer confirmation of our perception rather than contradict it,…
Yes, folklore and myth tends to do that – “the branch of the tree hit me, therefore a malevolent spirit lives inside it” etc. Through history we’ve shaped and formed these myths to fit with our subjective perceptions of reality. Since the ancient Greeks though some at least have had the sense to delve deeper than just perception and have developed more robust, logically consistent, functionally useful understandings of reality that dispel the non-answers of the superstitionists.
…while at the same time not contradicting the science discovered to date.
Utter bollocks. First you have no idea what science has discovered to date. The many corrections you’re given when you get the science wrong is evidence of that. Second, you dismiss at a stroke all of the scientific disciplines painstakingly piecing together our understanding of consciousness in particular, and you insert magic agencies into evolutionary theory so as to fit your circular reasoning mistake. Third, your mindless, unqualified, non-investigable claims and assertions are the very antithesis of the scientific method – that is, you remain rooted firmly in the “not even wrong” territory of intellectual gibberish.
Apart from all that though…
So again: why do you think a jig-saw with no pieces is more likely to give an accurate picture than a jig-saw with some of the pieces?
