Lewis Vaughn is the author or coauthor of numerous books, including Bioethics, Fifth Edition (2022), The Power of Critical Thinking, Seventh Edition, (2021), Philosophy Here and Now, fourth Edition (2021), and Living Philosophy, third Edition (2020), all published by Oxford University Press.  He also publishes Doing Ethics, Fifth Edition (2018) with W.W. Norton.

The book is comprehensive in taking up crucial aspects of critical thinking. I particularly applaud the inclusion of chapter two to help readers grasp the all-too-easy to make mistakes that impede critical thinking. The opening chapter does a great job of giving students a clear sense of not only what the rest of the book offers but also a clear sense of the meaning and purview of critical thinking. The last chapter is also vital, as ethics is all too often ignored as a vital component of critical thinking." -Jeffrey Nall
