It's true, of course, that not many people become professional philosophers. But neither do most history majors become historians or English majors go on to become novelists. The fact is that most students don't pick a major because they plan to make their living in that field. They choose a major based on their interests and on how well it will prepare them for the widest possible number of occupations after college. Let me explain.
Philosophy deals with theories about the most basic beliefs and values that people have.
These include topics like the nature of reality and human nature, the nature and sources of knowledge and morality, the proper structure for society and government, and the nature of religious belief. It also studies theories about the nature of science, art, language, and law. In this way, every philosophy major is exposed to the most influential interpretations of the most important issues people face across the entire spectrum of human experience. But more than simply learning about these issues, philosophy includes a keen training in logic and critical thinking - in the ability to argue and debate the truth of the various theories and viewpoints that are studied. It sharpens one's ability to spot difficulties, pose questions, and to weigh the evidence for and against the reasons given for any view on any topic.
