Logical Fallacies: Introduction by Dr. Jason Lisle
Whenever I hear people debating some issue (abortion, gun control, origins, religion, politics, etc.), I often spot a number of mistakes in their arguments. Mistakes in reasoning are called “logical fallacies,” and they abound in origins debates. I have often thought it would be fun to carry a little buzzer that I could push when someone makes a fundamental mistake in reasoning. Of course, that would be impolite.

Logic (the study of correct and incorrect reasoning) has become a lost skill in our culture. And that is a shame. It is a very valuable tool, particularly for the Christian who wants to defend his or her faith better.
