Redeeming Reason

Vern S. Poythress Explains the Laws of Human Reasoning and How to Apply Them in Light of the Gospel

Humans use reasoning to understand and order the world around us. We apply this logic in a variety of contexts, from classifying simple objects to considering complex philosophies. But how should our identity as Christians—made in the image of God (Gen. 1:26–27) with minds renewed by the Holy Spirit (Rom. 12:1–2)—inform our reasoning?

Vern S. Poythress explains how all human reasoning reflects God's nature. Providing a foundational understanding of God as the source of rationality, Poythress details the 3 fundamental laws of logic—identity, contradiction, and excluded middle—with a strong focus on analogical reasoning. This robust guide explains types of analogy, ethics applied to logic, the use of analogies in the doctrines of God, and more to give readers a renewed perspective on how to use reason as a follower of God.
