The First Principle of Logic


by Rob Lundberg

WHAT IS THE FIRST PRINCIPLE OF LOGIC?

The first principle of all knowledge is the law of noncontradiction. This 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. It is like saying, “my parents did not have any children that lived.” I guess I must not exist. But wait, I am typing this!

As you can see already, that violations of the law of non contradiction can easily be refuted by turning the claim on itself to show it to self implode.

The First Principle of Truth

What follows from the first principle of logic is its product known as truth. Of course if you have logical principles or laws of logic, then truth must follow. Truth is that what is or that which corresponds to reality. But when addressing the First Principles, what is this First Principle of Truth?  That is what this post is going to summarize.
