I liked this textbook so much that I went back after the class was over to finish reading it. One would think the topics covered would be common sense, and many of them are, but there are a lot of philosophical and logical principles being covered. Also, it helps to actually sit down and think about "common sense" topics sometimes. We don't do that enough.
Would recommend this book as a critical thinking textbook. Useful information. Found a questionable source cited, when the book was warning about questionable sources - that's a bit sad. Overall very recommended for clearer thinking.
