Oh, I see. Well, I guess you have a point there if you consider necessary/basal assumptions in a process as presuppositions. The difference I see though is that these "presuppositions" as used in science and the scientific method are in turn validated by their use in a way that isn't possible with a presupposition of a creator deity in any context you choose otherwise. Is there any presuppositions like this in science?
Well, Science doesn't interpret data, let alone assume anything on it - people do that. I disagree with you on not being able to prove/disprove scientific realism though, it can be demonstrated, and that demonstration is the evidence (though not absolute proof) of its validity. We make the same basal assumptions for syllogistic logic in philosophy, and I would imagine you accept that as being effective, no? The data from most scientific experiments are generally freely available so you can interpret the raw data yourself if you understand what you're looking at. The method used to acquire that data is what you seem to have issues with - and again, the basal assumptions used in the scientific method, are validated by their use in the same way syllogistic logic is validated by its use - are they not? We benefit from the practical applications of science all the time so I'd assume you would agree with that - but correct me if I'm mistaken.
Right, Wheeler's PAP isn't a scientific theory, nor is it considered in the scientific method as practiced so not sure why you think this is some sort of issue for science - the scientific method when applied to a problem generally produces meaningful and practically applicable results we can use. The "billions of years" are one such result borne out of the data from such scientific pursuits irrespective of such ideas as Wheeler's PAP, but instead is built on a well-established line of concordant foundational results that came before it. That's not to say it's infallible, but that the method (and any assumptions that came with it) have been extensively validated and is therefore most likely concordant with reality. If we come about information that upsets this paradigm, then the theories and data that came from them are revisited and/or refined to be more accurate. In some extreme cases, a theory might be discarded and/or replaced with a better theory.
In all this talk, it seems you have a problem with reality - do you not agree that we share this one and only reality we experience? Do you not agree that we can know things about it? Are you a solipsist?
Well, I haven't read up on McFadden's "Quantum Evolution" and don't intend to anytime soon, so I'll have to take it under advisement, I'm certainly not at the pointy end of that field...
well Sure, it continues to give us practical useable results all the time, so why not?
