@hawkeye10,
Must a methodology provide answers to be useful?
In this sense, philosophy is broad in scope, as we saw Aristotle wrote on ethics, rhetoric, politics, physics, etc. I personally have an affinity for French existentialism, and I see "practical" applications of Sartre's work in my everyday life. Any particular philosophical stream can help us organize our thoughts about the world, force introspection and self-reflection about the beliefs we hold, and challenge the legitimacy of the beliefs of others. In its most "useful" form, philosophy provides a groundwork for challenging political beliefs, which is eminently important and practical. For example, philosophical debate can challenge (or reinforce) different political systems, ideologies, and the practical effects of political decisions by state actors. It's not controversial to point out that the Canadian Charter of Rights and Freedoms is based philosophically on liberal theories of the individual and protection from the state. John Stuart Mill, therefore, played an important role in modern legal theory in Canada.
The questions are what are most important. If you aren't asking questions, then you are standing still.
