idealism i imagine depends on whose version you are referring too...the test i took is a standard personality profile, a lot like what employers use to decide who are good workers and who are not...but philosophy is personal perception, interpretation and opinion...so to say one thing is actually is rather incorrect, there's nothing actual about philosophy, that would be saying that there's something actual to personal thought. My example...

that's from dictionary.com...it's all open to perception.
