Firstly, theories are never proven. Only supported.
Secondly, not the same observations. But rather more observations. Preferably, by prediction.
Again quibbling on terms though, but mea culpa. Yes, supported.
The problem here is you would support theories by things derived from those theories. You say bombs that work or planes flying, support theories - but they were made or designed based on observations utilised to make them. So these are examples of the 'same observations' merely repeated, not more observations. You are being inconsistent.
Further, if I use astrological tables to investigate the position of the stars at my birth, I'd have found my birth-sign. Further I can predict vague enough traits associated with certain heavenly bodies that can then be applied to my life, creating a semblance or appearance of accuracy. Does this support Astrology? Didn't its predictions thus bear out as a system?
But anyway, yes that is how Empiricism functions, via observations. You still have not shown it valid therefore though. This is still a petitio principii, that a system reinforces itself by its own rules. For more observations does not really show anything new to something already based on taking observations - you aren't supporting the method, merely applying it further. Further observation merely refines the argument, but doesn't show its validity.
I don't "assume" the validity of empricism. I conclude it. I base it on its track record.
Empiricism demonstrably works. It is through empirical inquiry that we advance in our knowledge about reality. It's how we succeeded in building machines of several tons that nonetheless are capable of flying and even escaping earth's gravity.
Do you know of a better method?
Petitio Principii again. You must assume it valid to conclude it is, if you are doing so by Empirical means.
You are anyway assuming reality equates to materialism alone here, confusing ontological naturalism to methodological naturalism, and seeming to confuse Scientific Method with all of Epistemological investigation itself. All of this is again a Petitio Principii. This is quite a litany of, almost creedal, things that need to be taken solely on faith. It reminds me of the fundamentalist saying that I know the holy books are true because they say they are.
They support the theories.
Yes, they do. Exactly. They support theories we think wrong. It is simply hubris to think our theories today aren't of similar ilk; and we can somehow conclude our supports thus make our theories 'closer to truth' than their supports made theirs.
As I said, Galenic physiology is thought wrong, but it could succesfully treat some diseases and make succesful predictions (like arterial wave form). So it was better supported than the logikoi classical physicians it replaced - yet from our perspective a 'step away from truth', if we conclude our modern beliefs to be closer. It held sway for a thousand years, but clearly shows the lie that what is better supported is necessarily 'closer to truth' or that what can make succesful material predictions necessarily is either.
So, in your opinion, what does scientific advancement mean?
You don't think the general arrow of scientific advancement points to ever-more accurate models of reality - regardless of potential bumps or sidetracks along the way?
I really wonder how you can say such with a straight face while living in the digital information age where the idea of colonies on Mars aren't actually that far fetched... (if that is indeed what you are saying... and if it isn't, then what are you saying??)
No, what I am saying is Science doesn't presume what is reality, nor what is truth.
It uses methodological naturalism to investigate the natural world, hence its old name of Natural Philosophy. It constructs models seeking to understand the natural world, which it is continually building upon and making more coherent. At no point does it assume those models are anything but that - abstract models. If the entirety of it becomes incoherent or unsound, it will be discarded. To assume they are 'ever more accurate models of reality' is gross hubris and assumption, especially in light thereof that we had rejected many such well-developed models in the past and readopted previously discarded ones.
Well, yes....... and it is exactly thanks to that practice that we continously zero-in on the truth.
I don't think you fully grasp how Science actually works. At risk of seeming condescending, you make an hypothesis and test against it, seeking to falsify the same. This is then used to make new Hypotheses and the cycle repeats. It is however not a linear process. Many hypotheses are proferred, sometimes contradictory, that may pass current attempts at falsification. Other times new evidence unravels an hypothesis upon which hundreds of others were based, but it is not immediately apparent, as that hypothesis is nested deep within a whole collection of hypotheses considered plausible and scientific dogma (think of how quantum theory unravels so much as a quick example). It is a flawed human construct, with multiple intermeshed hypotheses that don't necessarily work with one another (quantum theory and relativity theory being incongruent for instance, hence the need for a theory of Everything). So it doesn't 'zero in on truth', but tries to construct a coherent and valid model based on empiric evidence, with varying degrees of success; but to assume this equates to truth, you are seriously overstepping the boundaries of Scientific Method and undermining its philosophical undercurrent of sceptical inquiry. It is because it is free to doubt, to change its mind, to go back on itself, to discard and pick up again, that it is so useful, durable and succesful. To presume cumulative advancement toward, and that present knowledge is closer to, some unknown endpoint of Truth, is simply fallacious and unscientific.
This is why what you describe is pseudo-science, something masquerading as if Scientific. It goes against the very writ of Scientific Method, which is built upon scepticism, even and especially of itself, that anything can truly be known with certainty. Scientific Method is just that - a method, a practical application of radical scepticism to assess claims. Not some system to determine truth, but a system to look for falsehood, so that amongst what remains, valence can be drawn based on current knowledge. The very structure of Science precludes ever reaching something 'true' and this includes determining if something is truly false. That is simply not how it works.
Defending the scientific method by insinuating that the scientific method doesn't lead to a better understanding of reality.
Owkay then.
Donkey.
Yes. I am defending it against ignorance of what it really is. It is about garnering a better understanding, but not about presuming what is reality though. Again, Methodological Naturalism as opposed to the Ontological variety.
You did something very similar in the past if I recall, where you misrepresented and misunderstood Occam's razor - another mediaeval philosophic invention. As that discussion ultimately went nowhere, I'd be a fool to repeat futile efforts here further too. I'd strongly suggest you read up on these things though, for the pseudoscientific worldview you espouse is profoundly stultifying to Scientific progress. But you can lead a horse to water, you can't make it drink.
I am done with this discussion. I bid you good day.
