Thinking 12:2 Style with The First Principles: The Principle of Logic

This past Monday night, being on Truth Matters and discussing logic and critical thinking, has sparked a thought for me to resurrect the series we did a few years ago on the other blog. So this is an oldie but fresh posting of a necessary series that should be kept before our eyes in a culture that so easily listens with its eyes and thinks with its feelings.

Some time ago, I had just concluded some lecture material on naturalism, atheism, and humanism.  Part of that material was a reminder of what constitutes a solid worldview by sharing with them what is known as The First Principles.

As I was working through them with the class, I was prompted into thinking that a subject like this might provide a short blog series.  So with that in mind, I would like to once again, share with you these First Principles with biblical references following.  

The ancient philosopher Aristotle showed how every science begins with certain obvious metaphysical truths that he referred to as first principles. Aristotle explained how these first principles form the very foundations upon which all knowledge rests.

These First Principles are the fundamental truths from which inferences are made and conclusions are based. They are considered to be self-evident truths which can be thought of as the underlying and the governing principles that shape a solidly cohesive worldview.

First Principle of Logic

WHAT IS THE FIRST PRINCIPLE OF LOGIC?

The first principle of all knowledge is the law of noncontradictionThis foundational first principle of logic states that opposite claims cannot both be true at the same time and in the same sense.

Biblical References Showing the Law of Non Contradiction

Matthew 21:25, “The baptism of John was from what source, from heaven or from men?” – Some questions only have a yes or no answer (either from heaven or from men).

2 Corinthians 1:18, “But as God is faithful, our word to you is not yes and no” – In order for a statement or message to be valid, it must be either “yes” or “no” and not “yes” and “no.”

Trying to refute to the law of noncontradiction is like saying that one ended sticks exist, or I cannot speak or in this case type a word of English. Violations of the law of non contradiction can easily be refuted by turning the claim on itself to show it to self implode.
