Logic is the study of good reasoning and thinking. We do this intuitively all the time. But we can also formalize what we're doing and study it. Doing so tends to improve one's reasoning and thinking. Being able to construct a valid argument makes one less vulnerable to criticism and less likely to be seduced by bad arguments. These are learnable skills and highly sought after. They also find useful application in the myriad graduate school entrance exams (like the GRE, LSAT, MCAT, and GMAT) that involve logic games/puzzles and critical reading questions. Finally, it turns out also to be quite satisfying to be able to PROVE things. Logic is fun! Thus, you should take PHIL 103: Logic, taught by Professor Matthew Slater.
