I've been educating myself with a number of books on Critical Thinking in order to improve my overall thinking, and by applying the techniques and principles to other areas of study - to utimately become a more effective learner. I enjoyed this book for several reasons - the book is very well written, it follows the curriculum of the AS level Critical thinking. The examples and exercises in the book where engaging, well chosen and modern. The skills are highly transferable to other areas, and are taught explicitly. I'm using this book in conjunction with Thinking Skills by J Butterworth and the Art of Reasoning by David Kelly. I'm still absorbing the skills of Critical thinking, since it is a highly practical skill- and hopefully I'll reap the benefits in due course. The journey to becoming a more effective critical thinker is most enjoyable when you encounter a book like this.
