You just finished arguing that "useful" is situation-dependent and now you want me to explain how philosophy is useful to
everyone? It isn't -- or, at least, it isn't useful in the same way to everyone in every circumstance. Philosophy is useful to the extent that it has a use. For a philosopher, philosophy has many uses. For an auto mechanic, not so much.
Really, you're asking the wrong question. Whether philosophy is "useful" or not doesn't yield any worthwhile answers. What you really want to know is whether philosophy is
valuable in an absolute sense. In other words, you want to know, in William James's term, what the cash value of philosophy is.
