"This text is exactly as advertised: an excellent introduction to both formal, sentential logic and informal, inductive reasoning ("critical thinking"). Of the numerous introductory "reasoning" texts that I have surveyed this one remains, to date, the only one currently on the market which extensively covers both deductive and inductive reasoning while remaining highly readable (i.e., does not read like a "math text") – no small feat."
— Michael Fletcher Maumus, Brooklyn College, City University of New York
"Merrilee Salmon's text wonderfully demonstrates the fact that both formal deductive logic and informal reasoning (critical thinking) are linked." "the text accomplishes what other logic books always force the instructor to develop on their own: a way to render philosophy and logic relevant to any student in any discipline while simultaneously demonstrating the importance of using language prudently."
— Philip Cronce,Chicago State University
"It covers the range of tools that you should want to give to a critical thinker. It also presents wonderful, real-life examples of both the good and the bad in human thought, giving the student a chance to reflect and respond."
— John Burn, Wayne State University
