On the contrary. I pointed out the previous commenter's hidden assumption that "it works" equals "it is valuable". If you believe they are equal, you need to justify your belief. I also pointed out that "it works" most certainly is not equal to "we know", unless you have a good justification to believe that this is the case. The goal of philosophy is to uncover hidden assumptions and question them.

No, it's concerned with truth, including the truth of good utility. But utility is never the primary concern, even among utilitarians and pragmatists.

Truth is a utility.
