God / Theism

Is God Real? Are the Laws of Logic Simply Human Conventions?

Are the Laws of Logic Simply Human ConventionsAll rational discussions (even those related to the existence or non-existence of God) are directed and restrained by the Laws of Logic. Only theism, however, can adequately account for the existence of these transcendent laws. If God exists, He is the absolute, objective, transcendent standard of truth; the Laws of Logic are simply a reflection of His nature. They exist as an extension of His rational thinking, and for this reason, they are as eternal as God Himself. Is God real? Without God as a source for the transcendent Laws of Logic, this question (and any logical journey toward the answer) would be impossible to engage.

As an atheist, I rejected the existence of God and offered a number of objections and alternative explanations in an effort to account for the Laws of Logic. We’ve been examining the theistic explanation for these laws and several naturalistic objections to see if atheism might offer a viable alternative. If the Laws of Logic aren’t simply a “brute reality” of our universe, could they merely be a matter of human agreement?

Objection:
Aren’t the Laws of Logic simply human conventions?

By “convention,” most people typically mean “a principle everyone has agreed on”. If Laws of Logic are simply ideas about truth people have agreed on, two things would be required before we could ever have a single Law of Logic: people, and agreement. But the Law of Identity (for example) existed before people were here to think about it. Prior to the existence of people “A” was still “A” and could not be “Non-A”. In addition, people disagree about what is true (or untrue) all the time, and our positions often contradict one another. How then, can the Laws of Logic be transcendent unless they exist for all of us, whether we agree with them or not? If the Laws of Logic are merely accepted human conventions, they would, in essence, be subject to a “vote”; the laws could be changed if enough people agreed.

Objection:
If God created the Laws of Logic, they are dependent on God. They are not necessary truths but contingent truths, and this means they are not foundational to the universe. And if God created the Laws of Logic, wouldn’t this mean He could change them whenever He wanted? Couldn’t God arrange things so “A” is also “Non-A”? After all, He created the Laws; He should be able to change them. But, the proposition “A” is also “Non-A” is irrational. If God is unable to change such a law, the Laws of Logic don’t appear to be dependent on God at all.

God did not create the Laws of Logic. These laws are simply a reflection of the thoughts and logical character of God, and as such, they reveal His logical, perfect nature. God, in His perfection, will not (and cannot) do anything to violate His own nature; He is not self-contradictory. Just as there is no such thing as a “square circle” (because this violates the nature of circularity), God cannot exist outside His nature, including the nature of His logical thoughts. Logic is foundational simply because God is foundational. The Laws of Logic are objective, unchangeable, internally consistent and transcendent because they reflect the nature of God.

Objection:
Aren’t there different kinds of Logic? If there are a variety of differing views and laws, the idea of transcendence is inaccurate. There is no need, therefore, for a transcendent source of these Laws.

While it is true that there are different categories of Logic applying to different aspects of propositional truth, mathematics and reasoning, the basic underlying principles of Logic remain intact and foundational. In addition, while many “laws of thought” have been proposed over time by great thinkers (i.e. Plato, Aristotle, Locke, Leibniz, Schopenhauer, Boole, Welton, and even Russell), these laws merely reflect, in one way or another, the same universal, pre-existent, objective logical axioms. In essence, we continue to find ourselves restating and reformulating the same Laws of Logic over and over again. When someone says “there are different kinds of logic” they are failing to recognize the objective, unchanging, underlying axioms. These foundational Laws of Logic remain constant within each system.

In order to live consistently within our worldview, each of us must examine the basis for our rational claims. If I don’t believe something, yet act consistently as though I do, my life is contradictory. If I reject astrology, but purchase a lottery ticket today based on the numbers provided in today’s horoscope, I’ve acted inconsistently. When I used to argue against the existence of God, I employed Laws of Logic my atheistic worldview could not provide. I had to borrow these concepts from the very worldview I was trying to defeat. Today, as a theist, I have an adequate foundation for these logical axioms. I can respond to objections in a way that is consistent with my worldview.

For more information about the scientific and philosophical evidence pointing to a Divine Creator, please read God’s Crime Scene: A Cold-Case Detective Examines the Evidence for a Divinely Created Universe. This book employs a simple crime scene strategy to investigate eight pieces of evidence in the universe to determine the most reasonable explanation. The book is accompanied by an eight-session God’s Crime Scene DVD Set (and Participant’s Guide) to help individuals or small groups examine the evidence and make the case.

    This is interesting…with all of these laws how do you reconcile that god cannot violate them, yet it seems like claiming Jesus is God and man at the same time would be in conflict with at least on if not all of them? Would you have to say Jesus couldn’t be God or not God, or Jesus cannot be both God and Man according to these laws? I would like your input because I am seeking truth but seem to find all these obstacles to simply “believe Christianity (Catholicism to be exact)
