Virtually all our emotional and sensory experience is something subjective and its sum total is not comprehensible in any strictly scientifically quantifiable way
Agree to disagree, I suppose. A huge chunk of how those mechanisms work and function together is well studied and largely understood. Where we have to agree to disagree is whether or not we're satisfied with what the scientific community has to say about it. There are certainly parts of it that aren't entirely understood, but hypotheses regarding these things are ultimately testable and measurable -- we just aren't done with that portion. The ability to vet a hypotheses against working models of the known principals and forces of the perceptible universe, however small or mundane, is the distinction that sets science apart from the other modes of study one can engage in to investigate phenomena. If a hypothesis can't be vetted within those terms, then it's not a scientific hypothesis.
The question we've come upon, several times, is whether or not that matters.
yet we also know that it is an inescapable and vital part of our life experience without which we could accomplish almost nothing ( including science/
I can see how people arrive at this conclusion. I've encountered it many times during raids on the forums when I was a regular over at Atheist.net. In my experience, there is no real way to discuss this without it unraveling into a debate, but I'll try.
Science goes beyond the senses to make observation. Science uses tools to process data, which we otherwise would be unable to detect, into information we are capable of perceiving. Math is one of these tools, but I am also speaking of chemicals and physical, technological devices. Science isn't empirical in a
common sense way. Science doesn't believe in common sense. In science, all must be vetted; further, all must be vetted beyond the limitation of the five senses, by whatever relevant means, and the resulting data must then be converted into a system of data that can be processed by the senses. This is why we know of things like viruses, DNA sequences, super novas, jet streams, tectonic plates, and on and on. These things are not readily observable by the five sense, but they are detectable by mechanisms and procedures that can turn the imperceptible data into something a human being can process. Science doesn't work the way every day experience and perception works -- it just doesn't -- if it did, we wouldn't really know most of what we know beyond what we can touch, taste, smell, hear and see with the naked senses.
Coupled with our ability to reason, these abilities give us plenty of reasons on a daily basis to make accurate decisions including ones like, "I saw an object, and think I may know what I saw." In fact we go much further than that and simply assume that most of the time what we think we see is what is actually there,
Again, you're talking about
common sense reasoning, which is science kryptonite. Common sense, as an idea, is the antithesis to the scientific method.
The common sense method is hypothesis --> presumption based on personal experience --> conclusion.
The scientific method is hypothesis --> control-based experimentation --> re-evaluation, weighing data against working models --> revised hypothesis --> control-based experimentation --> confirmation, weighing data against working models --> peer-review, including non-biased, second and third-party, control-based experimentation --> re-evaluation, weighing data against new working models and/or missed information --> working theory/new working model --> continued experimentation
These two concepts aren't in the same ballpark, in regards to what we're talking about.
Again, though, it comes down to how important you think science is in these types of situations. We seem to part ways philosophically when it comes to this.
and that process has worked so well for us over the millennia that it has facilitated our evolution into what we are now.
Which, after having discovered that fact, science has made strides to overcome. It's the very reason the scientific method exists -- our evolution-based, common sense deductions are weak tools in determining "truth." Science is well aware that, up until now, we've never had any use for such types of "truth."
And this process has no doubt also involved countless examples of previously unidentified things. So it isn't reasonable that after literally billions and billions of examples that have led us to where we are today, for science to suddenly step in during the last tenth of a second of this process and declare it invalid because it doesn't meet the "rigors of the scientific method".
But it is, for all the reasons you've just expressed.
If we based our knowledge of the universe on the things we were only able to discern using exclusively the
common sense deriving tools that evolution gave us, we wouldn't be having this conversation. Our ancestors had no need for these "truths," as I've said. They were largely satisfied with just making shit up, based on common sense observation (see: Creationism), and calling it a day. To reiterate, science doesn't believe in common sense.
