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. Critical thinking confers many benefits, including the ability to solve problems, to live independently, and to discover truth.

Reason, Emotion, and Watching Star Trek during the Pandemic

Preference can even at times trump solid evidence that points to the truth of an alternative conclusion.…

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.

Think Again: Logic vs. Passion

  Do you know that it’s possible to engage in a vigorous argument without your face turning red, your jugular vein popping out, or raising your voice?

Think Again: Logic’s Golden Question

What’s the point? That is the essential question to ask when critically examining arguments. In logic, the point is always what the argument’s conclusion indicates. Thus, the conclusion is also called the central point of the argument. It is what the arguer is attempting to prove and encourage others to accept. The sooner you identify the point of the argument,…
