While most other courses will teach you how to think about a particular subject, philosophy is unique in that it questions the process of thinking itself: By what logic do we arrive at answers? What is the foundation of answers, and the meaning of questions? How is it that we “know” something? What does it mean to “exist”, and what is the foundation of meaning itself?
Without examining these things you can be quite successful in life, but you’ll always be operating on a base of assumptions about life and thought that will limit how far you can go in your understanding of it. If this means nothing to you, you probably don’t need any philosophy; but if you’d like to discover more from life than just eating, sleeping and death, then it’s all the things we hold to be true, automatically and for granted, that demand our intense scrutiny.
