I believe you are proving my point. For example, the goal of much ancient philosophy was exactly what it meant to live a good life, and the theory of such was very well developed. Most of the culture you take for granted as 'common sense' is directly based on this philosophical development.

STEM at best tells you how to do something, but can never tell you what to do, or why to do it. For that you need philosophy, much more than philosophy of science.
