Philosophy is indispensable for understanding the foundational issues in many disciplines. Many important questions about a discipline, such as the nature of its concepts and its relation to other disciplines, are philosophical in nature. Philosophy of science, for instance, is needed to supplement the understanding of the natural and social sciences which one derives from doing scientific work itself. Similarly, philosophy of law, biomedical ethics, or history of philosophy gives you training in the sort of cross-disciplinary thinking important in today's fast-changing and interrelated careers. It can also help you do well in non- philosophy courses and in other majors or minors.
