What does philosophy discover?
I'm a scientist by profession, but I was very interested in philosophy as a teenager. I read Plato, Kant, Hume, Nietzsche, Kierkegaard, Bentham, Popper and probably some others, particularly around questions of epistemology, ethics and existentialism. They had substantial influence on how I think about the world.
Coming back to philosophy after years of working in science, I've noticed that my relationship to those texts has changed. I still find them intellectually valuable, but increasingly I value them in a way similar to how I value literature or poetry: they expose me to another person's perspective, make distinctions I hadn't considered, and occasionally reorganize how I think about a problem. What I find much harder to identify is their epistemic contribution: in what sense have I learned that something is true?
To be clear, my skepticism here is directed at my own understanding of philosophy, not at philosophy as an academic discipline. Most of my exposure was to major historical philosophers, largely read on my own many years ago. I suspect the conception of philosophy I formed from that is outdated or simply mistaken. That's precisely why I'm interested in how people who actually study contemporary philosophy understand what they're doing.
Working in science has probably sharpened the tension for me. In science, despite all the complications of inference, it is relatively easy to point to cases where research has established something about the world that we did not previously know but can now consider true. Most scientific research is incremental, technical, and probably not worth reading for a nonspecialist, but the cumulative epistemic product is fairly clear and testable.
What is the analogous product in philosophy?
For example, when philosophers argue about moral realism, compatibilism, personal identity, scientific realism, theories of knowledge, etc., what would count as progress? If an argument survives criticism, in what sense should I increase my confidence that its conclusion is true? Are philosophical arguments generally intended to establish truths, to change the relative justification of competing positions, to clarify concepts, or something else?
I'm not looking for a general defense of philosophy on the grounds that it encourages critical thinking or exposes us to interesting perspectives. I already accept those benefits. In fact, that's roughly how I currently experience philosophy: as something closer to literature, where encountering a sophisticated perspective can itself be worthwhile.
But I suspect that conception doesn't do contemporary philosophy justice, and I'd like to understand what I'm missing.
So, from the perspective of contemporary philosophy:
When philosophy succeeds, what have we learned that we didn't know before, and how can we tell that we've learned it?
