I'm not sure what it is you mean by "philosophies" in this context. Things like stoicism, epicureanism, etc. seem closer to "lifestyles" than philosophy as it is used in a modern context. Under that use many self help or psychological theories could apply. But if you're talking about Philosophy as it is generally meant then rational philosophies could include: materialism, epistemology, logic, and a lot of other things.
Hello all,
I'm working on a top-level post about how Stoicism is an instrumentally useful philosophy to adopt, and figured I should give other philosophies a fair shake as well. Does anyone know of any other philosophies out there that seem to be practically useful or otherwise provide strategies and thought patterns that have practical value? A solid grounding in experimental research is of course desirable.
