I agree, and yet I hesitate. People who have taken one or two philosophy classes are often insufferable and not least to themselves (or so I suspect). E.g., there's no broadly accepted 'answer' in epistemology (can we know things? What does it mean to say we know something?), and in an intro class you're only likely to be introduced to the problem and a few of the historically popular responses. These may lead you to conclude that philosophy is a lot of sound and bespectacled fury, signifying nothing or else that your newfound cynicism about knowledge constitutes an important superiority over naive mortals.

Epistemology is just one example. Whatever tickles your brain in an introduction to philosophy--whether arousing your curiosity, 'clicking' with something long felt, or leading you almost to despair--you should treat as a diagnosis. Valuable information, no doubt, but almost worthless to you unless you go on to seek treatment, that is, to study it further.
