The assertion that we are left with only axiological concerns after the "end of metaphysics" is a perspective that some philosophers have entertained, but it's not universally accepted. It depends on how one interprets the idea of the end of metaphysics and the implications it carries.
For some thinkers, the end of metaphysics implies a shift in focus away from speculative inquiries about the ultimate nature of reality towards more concrete concerns related to human values, ethics, and practical living. In this view, questions about the nature of reality, existence, and ultimate truth may be deemed unanswerable or irrelevant, leaving ethical and aesthetic considerations as primary philosophical concerns.
This perspective can be seen in certain existentialist philosophies, which emphasize the importance of individual choice, responsibility, and authenticity in the absence of metaphysical foundations. Existentialists like Jean-Paul Sartre and Albert Camus, for example, argued that in a world devoid of inherent meaning or purpose, human beings must create their own values and meaning through their actions and choices.
Similarly, pragmatist philosophers like Richard Rorty have suggested that after the end of metaphysics, philosophy should focus on practical concerns and the improvement of human well-being rather than engaging in speculative metaphysical inquiries.
However, it's essential to note that not all philosophers agree with this view. Some argue that even after the end of traditional metaphysics, philosophical inquiry can still engage with questions about reality, existence, and knowledge, albeit in a different manner or within different conceptual frameworks. Additionally, critics may argue that reducing philosophy to solely axiological concerns overlooks the continued relevance of other philosophical domains, such as epistemology, logic, and the philosophy of science.
Overall, while the idea that we are left with only axiological concerns after the end of metaphysics is a valid perspective within certain philosophical traditions, it is not the only interpretation of the implications of the end of metaphysics, and it remains subject to debate and discussion among philosophers.
