Logic: A God-Centered Approach to Foundation of Western Thought by Vern Poythress and published by Crossway.
A full course in logic and its relationship to Christianity Logic: A God Centered Foundation to Western Thought is a remarkable achievement. For the well-rounded Christian looking to improve their critical thinking skills, here is an accessible introduction to the study of logic (parts 1 & 2) as well as an in-depth treatment of the discipline (parts 3 & 4) from a professor with 6 academic degrees and over 30 years experience teaching.
Questions for further reflection are included at the end of each chapter as well as helpful diagrams and charts that are appropriate for use in high school, home school, college, and graduate-level classrooms. Overall, Vern Poythress has undertaken a radical recasting of the study of logic in this revolutionary work from a Christian worldview.
