Chapter Outline

Introduction

You have likely heard the term “critical thinking” and have probably been instructed to become a “good critical thinker.” Unfortunately, you are probably also unclear what exactly this means because the term is poorly defined and infrequently taught. “But I know how to think,” you might say, and that is certainly true. Critical thinking, however, is a specific skill. This chapter is an informal and practical guide to critical thinking and will also guide you in how to conduct research, reading, and writing for philosophy classes.

Critical thinking is a set of skills, habits, and attitudes that promote reflective, clear reasoning. Studying philosophy can be particularly helpful for developing good critical thinking skills, but often the connection between the two is not made clear. This chapter will approach critical thinking from a practical standpoint, with the goal of helping you become more aware of some of the pitfalls of everyday thinking and making you a better philosophy student.

While you may have learned research, reading, and writing skills in other classes—for instance, in a typical English composition course—the intellectual demands in a philosophy class are different. Here you will find useful advice about how to approach research, reading, and writing in philosophy.
