My PhD thesis titled 'On what matters in assessing concepts' is in conceptual ethics, exploring various questions at the intersection of philosophy of language, social philosophy, and value theory. It addresses the following questions:
What can conceptual ethicists gain by appealing to the teleological features of concepts?
What is the connection between the existence of concepts in a language and the values of linguistic communities using them?
How can conceptual ethicists avoid unduly imposing their own local standards for assessing concepts on other cultures, while also remaining attentive to the cross-cultural applicability of their assessments?
How defective must concepts be for it to be justified to stop using them?
Can practical and epistemic considerations about the value of concepts be non-arbitrarily weighed on a balance?
