As I use the term, philosophy is critical thinking about fundamental matters, where “critical” includes identifying and evaluating justifications for beliefs about fundamental matters or proposing and defending such justifications. Like the notion of philosophy itself, what counts as fundamental is also contestable, but Phillip Hansen's characterization of its being “about how humans ought to live, about what is good for them” is an apt example. Macpherson certainly does attend to this and similar topics and he castigates his contemporary political scientists for neglecting them.
