哲学 (zhé xué) is the formal term for the academic discipline of philosophy as a field of study. It differs from 哲理 (zhé lǐ), which refers to a specific philosophical principle or profound truth, and from 理念 (lǐ niàn), which means a guiding concept or philosophy of an organization. 人文 (rén wén) is a broader term for the humanities as a whole, which includes philosophy.
