I'm a college student, hoping to enter a PhD program and specialize in philosophy of mind and language. I'm deciding if I should spend my electives on mathematics. My experience with math tells me that it furnishes the mind with superior logic, clarity of thought, and a solid scaffolding that helps me reach higher ideas. Often I find myself framing my philosophical ideas, lessons, and questions in ways that mathematics has taught me, not philosophy (although I think this owes to my longer experience with math). So I've been wondering, how much mathematics should an aspiring philosopher study, especially if he or she would like to delve into one of the more analytic sub-fields? I'm good at math, and I do not mind taking a number of advanced math courses, but frankly, I'd rather spend the extra course slots on subjects I prefer, like more philosophy or a foreign language.
