Logic

A Logical Worldview

The Christian worldview is not a mere assumption. It is the worldview that makes knowledge possible (Proverbs 1:7; Colossians 2:3). It alone provides the justification for those things we need for reasoning—such as laws of logic and uniformity.

Introduction to Logical Fallacies

Logic is a very valuable tool, particularly for the Christian who wants to defend his or her faith better. Mistakes in reasoning are called “logical fallacies,” and they abound in origins debates.

The Straw-Man Fallacy

The straw-man fallacy is when a person misrepresents his opponent’s position and then proceeds to refute that misrepresentation rather than what his opponent actually claims.
