Although you're abosolutely correct, there were philosophers who thought that we must go beyond philosophy, seeing philosophy as limited - the big three here are Marx, Nietzche and Freud (considered as a philosopher, anyway) - best put by Marx: "Philosophers have hitherto only interpreted the world in various ways; the point is to change it." - unfortunately, from at least of what I've seen, this kind of thinking has run out of steam in contemporary (especially "analytic") philosophy, and it's a shame.
