The question is there, whether we answer it or not.[/b]
On the other hand, it is still after we answer it too. And all that this implies.
Whatever one may think about the possibility of a designer, the prevailing doctrine—that the appearance of life from dead matter and its evolution through accidental mutation and natural selection to its present forms has involved nothing but the operation of physical law—cannot be regarded as unassailable. It is an assumption governing the scientific project rather than a well-confirmed scientific hypothesis.
No getting around that, right, Mr. Skeptic?
To put it schematically, the claim “Everything is subjective” must be nonsense, for it would itself have to be either subjective or objective. But it can’t be objective, since in that case it would be false if true. And it can’t be subjective, because then it would not rule out any objective claim, including the claim that it is objectively false.”
Cue [among others] Ludwig Wittgenstein.
A comprehensively reductive conception is favored by the belief that the propensity for the development of organisms with a subjective view must have been there from the beginning, just as the propensity for the formation of atoms, molecules, galaxies, and organic compounds must have been there from the beginning.
I know: HOW comprehensively reductive?
Are there any alternatives? Well, there is the hypothesis that this universe is not unique, but that all possible universes exist, and we find ourselves, not surprisingly, in one that contains life. But that is a cop-out, which dispenses with the attempt to explain anything. And without the hypothesis of multiple universes, the observation that if life hadn’t come into existence we wouldn’t be here has no significance. One doesn’t show that something doesn’t require explanation by pointing out that it is a condition of one’s existence. If I ask for an explanation of the fact that the air pressure in the transcontinental jet is close to that at sea level, it is no answer to point out that if it weren’t, I’d be dead.
Let’s just assume that, as with so many other things like this, we really don’t have a fucking clue. As to how. As to why.
But although realism does not add anything to the catalogue of entities or properties that a subjectivist believes to exist in the world, it does hold that certain truths that subjectivists think have to be grounded in something else do not have to be so grounded, but are just true in their own right. After all, whatever one’s philosophical views, so long as there is such a thing as truth there must be some truths that don’t have to be grounded in anything else. Disagreement over which truths these are defines some of the deepest fault lines of philosophy. To philosophers of an idealist persuasion it is self-evident that physical facts can’t just be true in themselves, but must be explained in terms of actual or possible experience, just as it is self-evident to those of a materialist persuasion that mental facts can’t just be true in themselves, but must be explained in terms of actual or possible behavior, functional organization, or physiology. The issue over moral realism is of the same kind.
So, given that, is it or is it not okay to, among other things, abort a human fetus?
