The document discusses the importance of critical reading for critical writing. It defines critical reading as making judgments about how a text is argued by reflecting on the thinking and research that has already been done on the subject. The keys to critical reading are to read looking for ways of thinking about the subject matter rather than just for information. When reading, the reader should avoid simply extracting facts and instead ask how the text works, how it is argued, how it reaches its conclusions, and how it can help develop their own argument.
