Philosophy 101 is the study of existential crises, ontological anxieties, and ontic dilemmas. It's like the existential version of "What do you mean by that?" but with more navel-gazing.
But don't worry, you don't have to actually understand any of this stuff. Just pretend you're a fancy French dude with a beret and a beret-sized existential crisis.

2. "The Metaphysics" by Aristotle (For when you need to get your mind blown)
3. "The Crying of the Dead" by Edgar Allan Poe (Just for fun)
