An introductory course in philosophy begins with Plato's Apology. Here Socrates famously states that ‘the unexamined life is not worth living for man’. The professor lingers on the idea. In this first week of the course they have already struck upon a justification for all of the torturous analyzing, arguing, and thought-experimenting that will follow in the next few months. Without these vehicles of ‘examination’, our lives are not worth living! The students may have experienced enthusiastic defenses of the value of academic disciplines from other professors, but this guy is selling the idea that philosophy is necessary for a meaningful life.
