Hawking contra Philosophy | Philosophy Now - 0 views
-
Science has always included a large philosophical component, whether at the level of basic presuppositions concerning evidence, causality, theory-construction, valid inference, hypothesis-testing, and so forth, or at the speculative stage where scientists ignore the guidance offered by well-informed philosophers only at risk of falling into various beguiling fallacies or fictions.

this diagnosis, or something like it, applies to a great many of the speculative notions nowadays advanced by theoretical physicists including proponents of string theory (Hawking among them) and some of the more way-out quantum conjectures. These thinkers appear unworried – blithely unfazed, one is tempted to say – by the fact that their theories are incapable of proof or confirmation, or indeed of falsification as required by Karl Popper and his followers. After all, it is the peculiar feature of such theories that they posit the existence of that which at present, and perhaps forever, eludes any form of confirmation by observation or experiment.

reliance on theoretical commitments that exceed the utmost scope of empirical testing is something that some philosophers would attribute even to basic physical laws or widely taken-for-granted scientific truths. On their view there is no such thing as plain empirical self-evidence, since observations are always to some degree theoretically informed. By the same token, scientific theories are always ‘underdetermined’ by the best evidence to hand, meaning that the evidence is always open to other, equally rational interpretations given some adjustment of this or that ‘auxiliary hypothesis’ or negotiable element of background belief.
