A Quote by Elliott Sober
The indispensability argument seeks to assimilate the epistemology of metaphysical statements to the epistemology of statements that are obviously empirical. I think it fails to achieve this goal. The argument does not refute the Carnapian thesis that scientific theories and metaphysical claims differ epistemologically - observations can provide evidence for the former, but not for the latter.

Dawkins’s problem is that he doesn’t know the difference between probabilistic empirical theorizing and strict metaphysical demonstration, and thus misreads an attempt at the latter as if it were the former. That is not to say that Aquinas might not be mistaken at some point in the argument – though obviously I don’t think he is – but if you’re going to show that he is, you first need to understand what kind of argument he is giving, and thus what kind of mistake he’d be making if he’s made one at all.
The indispensability argument says (roughly) that if you have ample reason to accept an empirical scientific theory that makes indispensable use of mathematics, and that theory entails that numbers exist, then you have ample reason to accept that numbers exist. The argument affirms the antecedent of this conditional, and concludes that you have ample reason to believe that numbers exist. What is striking about this argument is that it seems to show that the empirical reasons that suffice for accepting a scientific theory also suffice for accepting a metaphysical claim.
"Methodological naturalism" and "metaphysical naturalism" are terms that often surface in the continuing battle between evolutionary biology and creationism/intelligent design. The methodological thesis says that scientific theories shouldn't postulate supernatural entities; the metaphysical thesis says that no such entities exist. In this debate, God is the supernatural entity at issue; the question isn't whether science gets to talk about mathematical entities if Platonism is correct.
The quality of the human that precludes identifying the individual with the class is 'metaphysical' and has no place in empiricist epistemology. The pigeon hole into which a man is shoved circumscribes his fate.
There will be well-testable theories, hardly testable theories, and non-testable theories. Those which are non-testable are of no interest to empirical scientists. They may be described as metaphysical.
Some think to avoid the influence of metaphysical errors, by paying no attention to metaphysics; but experience shows that these men beyond all others are held in an iron vice of metaphysical theory, because by theories that they have never called in question.
To reject revelational epistemology is to commit yourself to defending the truth of autonomous epistemology.
Bealer argues that the kind of naturalistic view which Quine holds will rob him of the ability to make the normative claims which (many) naturalists wish to make in epistemology. I don't think this is right about Quine, but I'm certain it's not right about my own view. To the extent that I can show that talk of knowledge is firmly rooted within empirical theories where it plays an important explanatory role, I thereby demonstrate its naturalistic credentials.
I think Martin Luther correctly distinguished between what he called the magisterial and ministerial uses of reason. The magisterial use of reason occurs when reason stands over and above the gospel like a magistrate and judges it on the basis of argument and evidence. The ministerial use of reason occurs when reason submits to and serves the gospel…. Should a conflict arise between the witness of the Holy Spirit to the fundamental truth of the Christian faith and beliefs based on argument and evidence, then it is the former which must take precedence over the latter.
It can be a necessary conceptual truth that pains are painful without this ruling out the physicalist thesis that immaterial minds are impossible or the thesis that conscious states supervene on physical states. The necessity involved in these claims is nomological necessity, not metaphysical necessity (assuming that these are different).
Epistemology now flourishes with various complementary approaches. This includes formal epistemology, experimental philosophy, cognitive science and psychology, including relevant brain science, and other philosophical subfields, such as metaphysics, action theory, language, and mind. It is not as though all questions of armchair, traditional epistemology are already settled conclusively, with unanimity or even consensus. We still need to reason our way together to a better view of those issues.
If man has learned to see and know what really is, he will act in accordance with truth, Epistemology is in itself ethics, and ethics is epistemology.
If you have a very commanding argument that you cannot refute, not to accept the argument is to act irrationally.
Water is two parts hydrogen and one part oxygen. What if someone says, “Well, that’s not how I choose to think about water.”? All we can do is appeal to scientific values. And if he doesn’t share those values, the conversation is over. If someone doesn’t value evidence, what evidence are you going to provide to prove they should value it? If someone doesn’t value logic, what logical argument could you provide to show the importance of logic?
Should a conflict arise between the witness of the Holy Spirit to the fundamental truth of the Christian faith and beliefs based on argument and evidence, then it is the former which must take precedence over the latter.
Many witnesses to the shooting of Michael Brown made statements inconsistent with other statements they made and also conflicted with the physical evidence. Some were completely refuted by the physical evidence.
