A Logic Book to Help You Think for Yourself

Learning to think rigorously for oneself is one of the most important intellectual duties in life.

Think Again: The Danger of Preferential Reasoning

There seems to be a tendency in human beings to draw the logical conclusion that each of us prefers to be true. So when it comes to evaluating arguments for reasonableness and explanatory power, preference tends to weigh heavily in our final assessment. Preference can even at times trump solid evidence that points to the truth of an alternative conclusion.…

Think Again: Christianity’s Relationship to Reason

Are Christians well known for their careful thinking, or does faith do damage to reason? While skeptics sometimes question whether historic Christianity comports with a vigorous logical outlook on life and the world, the truth of the matter is that many advancements in the area of logic have come from the work of Christian scholars.
