Accounting for the 4 Fundamental Laws of Logic

The laws of logic are not relative conventions (or agreed upon principles).
  • They are absolute because they are NOT subject to "vote".
  • They are NOT based on human thinking since human thinking is often contradictory.
  • They are NOT derived through observing natural principles found in nature.
  • They are conceptual realities (they only exist in the mind).
  • They do not describe physical behavior of things since behavior is action and laws of logic are not descriptions of action, but of truth.
  • One has to use logic to try to disprove, refute, or even deny it.
  • Logic is necessary or indispensable in life. One literally can not live without it!
Logic or reason is undeniably true, unavoidable, self-evident and applicable to all coherent discussions. That is, one cannot NOT use logic (at least not so and engage in an intelligible discussion at the same time). Logic is a necessary precondition of all intelligible thinking.

The following are the four primary laws of logic:

1- The Law of Non-Contradiction:
Something cannot be itself and not itself at the same time in the same way and in the same sense. (A cannot be A and not A at the same time.)

2- The Law of Excluded Middle:
A statement is either true or false. Thus the statement "A statement is either true or false" is either true or false. A is either A or not A. (See, e.g., Matthew 12:30.)

3- The Law of Identity:
Something is what it is. Something that exists has a specific nature. A is A or A is identical with A. (e.g., the Christ of the Bible is not the "Christ" of the cults or the occult.)

4- The Law of Logical or Rational Inference:
Law of Sufficient Reason. There should be sufficeint reason to all happenings.
If A=B, and B=C, then A=C.
For example, the word trinity is not found in the Bible, but the concept is found in the Bible.
(see, e.g., Deut. 6:4; Eph. 1:3; John 1:1; 20:28; Acts 5:3-4; and Mark 12:29-30).

The atheistic worldview cannot account for the laws of logic/absolutes, and must borrow from the Christian worldview in order to rationally argue.

We are created in the imago Dei--the image of God. This includes, among other attributes, the ability to reason. This entails the value of evidence and reason.

For example, we are told in 1 Corinthians 10:31 "So whether you eat or drink [or think] or whatever you do, do it all for the glory of God."

We are told in 2 Corinthians 10:3-5 "For though we live in the world, we do not wage war as the world does. The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ." I believe that reasoning well is one of those "weapons."


  1. Thanks for this post. I am writing about "what people believe" and this information is helpful. Isn't it interesting that many people believe that hell does not exist simply because they believe it does not exist?

    1. In lieu of your Hell question/topic: https://medium.com/@ikem_nachi/hell-18a28e2a9097

  2. I would be interested in reading your article "what people beleive" if you would like to share it with me.
