Philosophy is a theoretical science with practical applications
Moreover, philosophy is not especially an empirical science as are biology and physics, sociology and psychology. The notion of person, for example, is not discoverable by studying the natural and social worlds or by taking a survey of people’s opinions. Rather the concept person is decided upon, not without considerable discussion and controversy, beforehand and then applied to such concerns as medical ethics, artificial intelligence, and animal rights. Of course, the notion of person becomes refined in the process of its application to changing circumstances. Yet, even biologists step outside that role to become philosophers when they work at defining life and then apply their definition to a virus to see whether it satisfies the definition. And while philosophical reflection might aim at practical concerns, it is really more a theoretical science than a practical science.
