The skills of Critical Thinking are important whatever subject you are studying. They enable you to assess what s been said or written by asking the right questions: What does this mean? What else could it mean? What other evidence do I need? With your answers, you can suggest other explanations or scenarios: Perhaps it s this rather than that . As a creative, enquiring thinker, you can then move on to produce well-argued material of your own. This new edition has been totally updated, but it continues in the tradition of the earlier editions in that it is invaluable for all students, whether you re doing a course in Critical Thinking (like the AS-level) or not. It quite simply covers everything you need to become a skilled Critical Thinker.
