Biblical Logic: In Theory and In Practice by Joel McDurmon

Biblical Logic: In Theory and In Practice review by Mike Robinson

Don’t care if you’re an apologetic enthusiast or an indolent irrationalist. Don’t care if you’re just a semester away from a degree in epistemology. Don’t care if you’re William Lane Craig and have won every public debate against atheism you have participated in. Don’t care if you have towering IQ and can read Plato in classical Greek. All communication presupposes and requires the utilization of the laws of logic (Law of Identity: LOI; Law of Non-contradiction: LNC). Thus:
You’re stuck
You’re bond
You’re tethered
You’re fixed, connected, attached to and You’re epistemologically glued to the Laws of Logic (LL).

As a nominalist, relativist, anti-realist, irrationalist, or a strict materialistic atheist try as you may, but there’s no escape.
And in his innovative fresh book, Biblical Logic: In Theory and In Practice, Joel McDurmon builds a strong case that real logic must be built upon and spring from the nature of God and His revealed Word. The author rightly notes that “Logic, being part of creation, cannot act as the standard for judging all of reality, especially not truth about God Himself. Logic has limits. Does this mean it has no place in the Christian life? Certainly not. In fact, only the nature (including the omniscience and omnipotence) of the Creator God can guarantee that logic works and correlates with reality… Logical laws are necessary tools…” (p. 32).

The author encourages Christians to study logic, informal and formal fallacies, and critical thinking as the reader is trained to resist the anti-rational and non-biblical notions of truth displayed in our culture.

“The `laws of logic’ determine the forms which valid or invalid arguments can take” (p. 14).

In Biblical Logic the reader learns about:

• Critical thinking
• The Theological Foundations for Logic
• Fallacies of Worldview
• Fallacies of Representation
• Hidden Presumptions
• Fallacies of Property
• Fallacies of Relevance
• Fallacies of Time
• And much more within the pages of this instructive, yet alluring volume.

The author summarizes the ontic necessity of God to account for the Laws of Logic: “From the biblical point of view we learn that God makes orderly experience possible because of His own self-consistent, self-authoritative, and faithful nature… Man must think God’s thoughts after Him…” (p. 30).
This page-turner educates the reader with powerful concepts made simple as the author calls Christians to base their worldview, philosophy, and method of logic on God’s infallible word; by this standard one can know and account for logic and truth. Following Van Til’s lead the author recognizes that “the God of the Bible … alone makes truth and logic possible” (p. 33).

Logic … presupposes that our thoughts correspond to reality and this requires that reality be objective… Reality, in other words, must stand true independently of man and cannot depend on man for meaning… This in turn requires some Source of objectively, which we find in the self-consistency of the Creator who upholds all things by the word of His power (Heb. 1:3), who Himself does not change (James 1:12, 17; Numbers 23:19), and who creates and orderly creation (p. 27).

McDurmon adds that “the proper understanding of logic requires a proper understanding of theology” (p. 21). Inasmuch as “reasoning will show that only the Christian Trinity fills all of the requirements of human experience, and thus this Trinitarian God must exist before human experience can mean anything… Given this, the ultimate source of human knowledge abides in God’s Revelation to mankind—a revelation of Himself found generally in nature and man himself, and specially in Scripture” (p. 396).

Furthermore McDurmon discusses the views and methods of logic from thinkers such as:

• Aristotle
• Gordon Clark
• John Frame
• Cornelius Van Til

• Vern Poythress (McDurmon quotes Poythress: “Human reason and the use of logic are dependent on knowledge of God and are guided by it. … This dependence becomes more obvious when we root logic in the Trinitarian character of God” (p. 38).

This is a fine book for the busy minister, scholar, seminary student, and budding apologist.

NOTE: The author discusses the Laws of Logic (LOI & LNC) in some detail but not exhaustively.

Book Review of Greg Bahnsen’s Presuppositional Apologetics: Stated and Defended

 

greg bahnsen stated defended reviewThe publishers bequeath eager Van Tilians a new and superb offering from the late Dr. Greg L. Bahnsen. Bahnsen, as a formal debater, was regarded as the “man atheists feared the most.” This new book, “Presuppositional Apologetics: Stated and Defended,” demonstrates some of the reasons for such an assessment. The author has been deeply missed and this volume of systematic apologetics is a blessing to all who sought a fresh resource that would be compatible with his earlier books. This precise and orderly defense of the faith was not available because it was lost. It was only recently discovered and brought to press. Bahnsen’s philosophical labor is clear, succinct, and commanding. The editors supply the brilliance of Bahnsen’s apologetic in a methodical and lucid manner (Joel McDurmon put in a lot of hard toil as Editor). This is a brand new publication that helps make Van Til’s remarkable thought accessible to ordinary believers as well as the most widely read scholars.

In this volume we have apologetic clarity and a philosophical depth illuminating issues surrounding a faithful defense of Christian theism. I encourage all to purchase this stupendous edition of Bahnsen’s scholarly toil to help equip the church to proclaim and defend the truth of the ontological Trinity.

 

Bahnsen offers many unique gems in this never-before-published volume including powerful and lengthy critiques of the apologetic systems of:

- Gordon H. Clark
- Edward Carnell
- Francis Schaeffer
- Ronald Nash (this one is brief but convincing).

Additionally he provides a plethora of Vantilian type quotes from Clark (2 ½ pages), Carnell, and Schaeffer. This alone makes “PASD” worth much more than the cost. This is an absolutely necessary apologetic resource for the active apologist.

Greg Bahnsen wrote that the unbeliever “has no intelligible place to stand, no consistent epistemology, no justification for meaningful discourse, predication, or argumentation.” Other than that, you’re fine! Bahnsen goes on to lay bare anti-theism: he writes that “the Christian worldview is true because of the impossibility of the contrary. When the perspective of God’s revelation is rejected, then the unbeliever is left in foolish ignorance because his philosophy does not provide the preconditions for knowledge and meaningful experience.” Only Christian theism can supply the pre-essentials needed for debate, evidence, and knowledge. Bahnsen asserts that “the proof that Christianity is true is that if it were not, we could not be able to prove anything.”

Bahnsen was once described as “the man atheists fear most” because of the controversy surrounding the Bahnsen-Martin debate, which was cancelled by Michael Martin.

Some quotes: “In various forms, the fundamental argument advanced by the Christian apologist is that the Christian worldview is true because of the impossibility of the contrary. When the perspective of God’s revelation is rejected, then the unbeliever is left in foolish ignorance because his philosophy does not provide the preconditions of knowledge and meaningful experience. To put it another way: the proof that Christianity is true is that if it were not, we would not be able to prove anything.” “An unbeliever is not simply an unbeliever at separate points; his antagonism is rooted in an overall philosophy (Col. 2.8) which is according to the world’s tradition; thus is an enemy of God in his mind (Col. 1.21; Jam. 4.4) and uses his mind to nullify or obviate God’s word (Mk. 7.8-13).”

“In what way does knowledge go beyond belief? Knowledge includes having justification or good reason to support whatever it is you believe. Imagine that I believe there are thirty-seven square miles in a particular city, and imagine also that it just so happens that this claim is accurate – but imagine as well that I simply got this answer by guessing (rather than doing measurements, mathematics or checking an almanac, etc.). I believed something which happened to be true, but we would not say that I had ‘knowledge’ in this case because I had no justification for what I believed. When we claim to know that something is true, we are thereby claiming to have adequate evidence, proof or good reason for it.”

“Imagine a person who comes in here tonight and argues ‘no air exists’ but continues to breathe air while he argues. Now intellectually, atheists continue to breathe – they continue to use reason and draw scientific conclusions [which assumes an orderly universe], to make moral judgments [which assumes absolute values] – but the atheistic view of things would in theory make such ‘breathing’ impossible. They are breathing God’s air all the time they are arguing against him.”

I would add: Suppose my wife took my i-pod off our dinning table and put it on an obscure shelf before she ate lunch. When I returned home and found it missing on the table, I phoned my wife. She said that she needed space to eat and so she put my iPod away. I asked her how I could find my iPod now that she moved it to an unknown location. She told me that she had put a post-it note on the iPod. That, of course, would not have done me, her befuddled husband any good. The portable stereo would have been hidden, and a note on a hidden stereo was lost to me until my wife informed me where she put it. Such is the problem of an unsaved person. He is lost, and cannot use his own reason or experience to find his way to truth. He is lost, and his autonomous reason is lost with him. The only way he can find the truth is through an objective, unchanging source. The God of the Bible is the unchanging rational bedrock and fountainhead.

The biblical God is the pre-necessity for self-knowledge and the intelligibility of the world. Without God, man is lost, holding his own note of a man-made holy book. Only through Yahweh and His revelation can a man be found and have an objective basis for truth. God is the absolute and transcendental necessity for the intelligibility of all human apprehension. He is the precondition for the grounding and understanding of knowledge. Buddhism, Hinduism, and atheism cannot justify knowledge or truth. If you do not presuppose the truth of God in Christ, you cannot make sense out of the cosmos and all of reality. Christianity is true not because it makes better sense, but because it alone supplies the foundation for logic; it is true because without it you cannot make sense of anything.

All other religions, philosophies, and worldviews lack the transcendentally required precondition (Yahweh) for predication, intelligibility, logic, ethics, and truth. Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me” (John 14:6). Only the transcendent, aphysical, invariant, and multi-personal-unified God can provide the necessary preconditions for the transcendent, aphysical, invariant, and multi-unified laws of logic. I argue from the shoulders of giants as I press the truth that there is “absolutely certain proof for the existence of God and the truth of Christian theism.

Even non-Christians presuppose its truth while they verbally reject it.” We ask the nonbeliever “what are the conditions that make thought possible?” Only the Triune God can furnish those preconditions to establish the rational flooring for intelligibility. Van Til called this truth “the method of implication into the truth of God a transcendental method. That is, we must seek to determine what presuppositions are necessary to any object of knowledge in order that it may be intelligible to us.” Transcendental scrutiny of anti-theism demonstrates that it is self-destructive inasmuch as it fails to give what it does not possess. Man is devoid of eternal omniscience, aseity, sovereignty, and omnipotence.

Bahnsen set forth transcendental analysis as that “which asks what the preconditions are for the intelligibility of human experience. Under what conditions is it possible, or what would also need to be true in order for it to be possible, to make sense of one’s experience of the world? To seek the transcendental conditions for knowing is to ask what is presupposed by any intelligent experience whatsoever.” Humankind does not need to exist for the intelligibility of the universe. Mere men cannot supply the transcendental conditions that are needed for the laws of logic, love, and morality.

Van Til contended that “the general precedes the particular” in our reality. This implies that the anthropology of atheism cannot supply the general and universal realities that must be present, for the necessary and unavoidable transcendental conditions listed above.

Dr. Greg L. Bahnsen had heart valve implant surgery on December 5, 1995. After the completion of the operation, serious complications developed within twenty-four hours. He then became comatose for several days and died on December 11, 1995 at the age of forty-seven.
