Introduction

Introduction to a new, updated series of “Lessons in Logic” videos.

Why Study Logic?

• Logic is a subset of Epistemology; how we know things.
• Logic helps us think rationally
• Logic helps us understand what we believe and why we believe it
• Logic helps us recognize & refute poor arguments
• Logic helps us contend for the Faith

Types of Logic

Formal

•  The investigation of an argument based upon the construction of the argument itself and the validity of the premise. If these conditions are met, the conclusion necessarily follows.

Informal

•  Addresses arguments in natural language.
• Often involves arguments that are technically valid under the rules of formal logic, but fail because the conclusion doesn’t follow from the premise

You Encounter Logic Every Day

• When you discern whether something is food or not food, healthy or unhealthy, fresh or stale.
• When you put fuel in your car. 
• When you encounter advertising.
• When you watch the news.
• When you hear political debates.
• When you read scripture, or hear presentations by preachers, teachers, or even heretics.

Logic in Scripture

“From any tree of the garden you may eat freely, but from the tree of the knowledge of good and evil you shall not eat, for in the day that you eat from it you will surely die.”

Genesis 2:16b-17

But if there is no resurrection of the dead, not even Christ has been raised; and if Christ has not been raised, then our preaching is in vain, your faith also is in vain. Moreover we are even found to be false witnesses of God, because we testified against God that He raised Christ, whom he did not raise, if in fact the dead are not raised. For if the dead are not raised, not even Christ has been raised; and if Christ has not been raised, your faith is worthless; you are still in your sins. Then those also who have fallen asleep in Christ have perished. If we have hoped in Christ in this life only, we are of all men most to be pitied.

1 Corinthians 15:13-19
