“[...two main divisions of philosophy.] The questions in the first group, the questions about being and becoming, have to do with what is or happens in the world. Such questions belong to the division of philosophy that is called theoretical or speculative. The questions in the second group, the questions concerning good and evil, or right and wrong, have to do with what ought to be done or sought, and they belong to the division of philosophy that is sometimes called practical, and is more accurately called normative.
