We live in an information age, but it is increasingly difficult to know which information to trust; most of could stand to be more perceptive, more critical, and more judicious readers. After laying out general principles of reading nonfiction, Thomas Foster—who is indeed a professor—offers advice here for specific reading strategies in various genres from histories and biographies to science and technology to social media. Arguing that we can be better citizens through better reading, Foster clarifies the best methods for understanding writers' biases, interrogating claims, analyzing arguments, remaining wary of broad assertions and easy answers, and thinking critically about written and spoken materials.
