How to Think Critically begins with the premise that we are all, every day, engaged in critical thinking. But just as we may develop bad habits in daily life if we don't scrutinize our practices, so we are apt to develop bad habits in critical thinking if we are careless in our reasoning. Readers are presented with a traditional step-by-step method for analysis that can be applied to all argument forms. Hundreds of exercises (with solutions) are included, as are several random statement generators which can be used to create thousands of additional examples. Venn diagrams, truth tables, and other essential concepts are presented not as definitions for academic study but as tools for better thinking and living. This second edition is substantially revised and improved throughout, and includes an all-new chapter on the applications of critical thinking in online contexts.
