Reasoning by Presupposition: The Bahnsen-Smith Debate

I was perusing the apologetic blogs a few months back when I came across a comment by an atheist who claimed Christians never refer to the Bahnsen-Smith debate (although that interchange was more a moderated conversation than a debate). Well, that claim is not true. To rebut that claim, here is a link to the audio of that debate. A transcript of the audio can be found here. Another post of the dialog can be found here. This dialog is well worth studying to understand Bahnsen's use of the presuppositional apologetic. Apparently, that atheist thought Smith bested Bahnsen in that encounter. Incredible! Such an opinion, as we will see below, betrays superficiality and an unstudied philosophic naivete. Smith,and a caller-in named Max, clearly had no clue as to what hit them. Bahnsen's irenic answers rebutted all of Smith's claims.

One particular point, that has prompted the title of this article, was when Max charged that Bahnsen merely presupposed God.  Of course, it is not the case that we merely do so (as if, the presupposition of Christianity is a fideistic and unargued assumption). Bahnsen's reply that atheists presuppose atheism was priceless.  This is a perennial blind spot of atheists -- they think they are devoid of presuppositions and are staunch advocates of non-circular reasoning. Nothing could be further from the truth.  Atheists, in fact, argue presupposing atheism (consequently, this atheist's charge against Christians commits the fallacy of special pleading, sometimes called "the double standard fallacy"). However, the fact that both sides have presuppositions does not reduce the debate to a stand off. Not all presuppositions are "created equal." The problem for the atheists is that they have a multitude of unintelligible contradictory assumptions and viciously circular arguments, none of which are mutually coherent, and none which they can make good. This fact renders the atheist's presupposition(s) false and destroys his pretense to knowledge of any sort. This fact is evident in the many debates of presuppositionalists with atheists. Some atheists will even admit (on the basis of their assumptions, of course!) there is no certain knowledge or express doubt that knowledge is possible (not realizing the inherent self contradiction in such claims -- since they must know something in order for their language to intelligibly express their doubt. To put it ironically: "Why should anyone listen to someone who believes he doesn't know what he's saying?") On the other hand, the Christian presupposition is intelligible and provides the necessary grounds for knowledge and for the intelligibility of all of human experience. So again, there is no "stand off."

Here are a few more of the high points in the dialog:

• Max claimed reason is "natural!"  Another priceless moment.  Bahnsen pressed the point that abstract entities are not natural.¹  All Max said by way of "rebuttal" was a repeated "Oh boy!"  Bahnsen challenged atheists to live according to their presuppositions -- something they never do.
• Smith assimilated physical causation and logical laws (logical "law of identity" for instance).  Bahnsen succinctly pointed out that such is a major philosophical error.²  For starters, matter does not move according to abstract laws of rational thought (logic) -- matter obeys inviolable physical laws based on the properties of matter. The material universe is completely oblivious to abstract laws of logic. Laws of logic are standards of rational thought -- laws that can be violated by flawed reasoning.  As we have mentioned repeatedly, laws of logic presuppose minds with rational freedom (independent of material causation) and mental causal efficacy -- something totally antithetical to a universe composed solely of matter moving according to chance and causally inviolable physical laws. (In the materialist universe the only causality is, de facto, physical.) To put it another way, laws of logic are necessary and non-contingent; on the other hand, the physical world is contingent and the laws of physics are not necessary. (If they were, empirical science and experiment would be unnecessary.) This is usually stated succinctly by the phrase "logic says nothing about the contingent world." We should also point out that physicists can construct a multitude of consistent theoretical models of the material universe with existing and hypothetical entities, differing mathematical structures, different causal interactions, different values of fundamental constants, and so on. All of which show that the actual physical reality in which we live is not necessitated by logic. To summarize, logic and physics are categorially distinct. Contra Smith, logic cannot be reduced to physics.
• Smith trotted out the tired and fallacious "Euthyphro dilemma" to counter Christian moral claims.  Bahnsen succinctly rebuffed Smith by pointing out that Christian moral claims are rooted in the character of God Himself.  In Christian theism, God is ne plus ultra³. There is no "super-reality" above God; no laws above God.⁴  

In summary, Bahnsen  began the dialog by engaging Smith on the three fundamental areas of philosophy: (1) What exists? What is real? What are the constituents of reality? (Metaphysics/ontology); (2) How does one know what one knows? (Epistemology) and (3) How should we lead our lives? (Ethics).  Beyond Smith's philosophical naivete and reasoning errors, Smith, like all atheists, did not even begin to provide intelligible answers, based on his godless reality, in any of these areas. Smith's materialist atheism is: (1) metaphysical irrationalism (espousing the ultimate chance nature of reality); (2) provides no self-attesting theory of knowledge (rendering knowledge impossible, and thereby, Smith has no ground from which to criticize anyhthing); and (3) provides no basis for the existence of absolute morality or ethical truth (morality is not a property of material systems).  All through the debate, Smith argued in vicious circles and merely assumed the existence of human rational freedom (which is incompatible with the assumption of material monism), logic, moral laws, abstractions, conceptual reasoning -- all of which inexplicably spring out of chance and physical (material) causation (or, alternatively as in platonistic pluralism, are an incoherent plurality of independent and ultimate brute entities suspended in the "void").  As Bahnsen pointed out, all of these are problems in Smith's atheist universe, but not for Christianity. (In fact, Smith is assuming facts that are borrowed from Christian theism.) Smith's atheist presuppositions thus have been shown to be incoherent and self-contradictory on the atheist's own ground, while the Christian presupposition and Christianity is vindicated.  

Postscript

During the call-in section, Smith responded to a question regarding the Bible. Smith responded, "Well, I mean there are some decent things in the Bible, sure. There are some elegantly expressed moral maxims, that sort of thing." (emph. added.) Bahnsen, probably due to lack of time, didn't respond to this but the reply to this sort of remark is: "On what standard does Smith rely to determine morals?" Would he claim that standard is absolute and knowable? On Smith's view the moral statements of Christ would be no more authoritative than those of any other; merely subjective opinion and non-absolute. The fact that Smith likes some of them is not a basis for absolute morality. Some people like Coke, others Pepsi. Smith, like all unbelievers, is his own ultimate, and arbitrary, standard.

1 Abstract entities, such as the laws of logic, are immaterial and not extended in space. As, such they are not empirically accessible; they are not natural objects perceived by the senses. For example, the law of deduction called "modus ponens" cannot be seen with the eyes. The question of the reality of abstract entities (especially universal and invariant concepts such as mathematics and logic) and conceptual knowledge lies at the root of the well known failures of rationalism, on the one hand, and empiricism, on the other, to provide a foundation for human knowledge. Both schools ended in skepticism regarding human knowledge. One should also consider that the modern phrase "logical empirical method" merely linguistically conjoins the two philosophical schools and thereby glosses the problems of both without solution, yet admits the distinction between the abstract and the natural. Stated in other terms, this dichotomy is also the distinction of deduction (necessary truths of reason) versus induction (contingent truths derived from generalizations of particular sense data). Bahnsen's point is that the atheist "universe" provides no intelligible account for either reason (human rational autonomy and conscious thought independent of material causation, existence and reality of universal laws of logic, etc.) or empirical knowledge/induction (given the atheist's commitment to ultimate chance and the irrational nature of the universe as embodied in quantum mechanics). On the atheist view, there is no bridging of the gap between the immaterial transcendent and unchanging truths of, say, logic or arithmetic, and the immanent and ever changing world of material flux. The problem that the atheist has with providing a justification of induction is well known -- it is a principle that cannot be deduced nor inductively derived (which is vicious circular reasoning and question begging). On the other hand, the transcendent God of Christian theism provides the intelligible answer to both deduction/reason (man is created in the image of God, the ultimate rational being and the source of man's reason -- behind the mind of man is the mind of the eternal God) and induction (God has created and faithfully sustains the cosmos ("...in Christ all things consist." Colossians 1:16-7). Further the existence of universal abstract entities, in that they are the contents of thought, are not eternal self-existent things existing in a mind-independent platonic world of ideas, but rather, the thoughts of the eternal God. They are real; and man, as the rational image of God, is to "think God's thoughts after Him," as Van Til has said. ^↩
2 Smith fallaciously used the example of the "Law of Identity" as "support" for his claim. Rather than the law of identity, one might think that the material conditional of logic ("if P then Q") would provide a more plausible support. However, it is generally known that the material conditional does not represent the concept of causality. See, for example, Paradoxes of Material Implication (in particular, see the example of switches in a series circuit in the section on "Simplification"), Material Conditional; and Causality (section titled, "Causality contrasted with conditionals"). Incredibly, Rudolph Carnap (a logical positivist) makes the philosophical error of representing causal laws via the material conditional in chapters 1 and 20 of An Introduction to the Philosophy of Science. ^↩
3 Latin, literally,"no more beyond." ^↩
4 Amazingly, Michael Martin also fatuously uses a version of the "Euthyphro dilemma" in his flawed TANG ("Transcendental Argument for the Non-existence of God").  The Euthyphro dilemma presupposes a mythological platonic reality of ultimate abstract moral laws to which all the "gods" and man are equally subject (and of which laws they somehow have knowledge) -- as such, it is contrary to the claim of Christian theism that God is ultimate.  Thus Martin's counter does not apply -- it is a straw man. It is a logical fallacy of the most egregious type to assume the truth of "not A" to refute "A." TANG as a refutation of TAG is an utter failure. TANG is not even analogous to TAG. To be analogous, TANG would need to show: (1) that the Christian conception of God is contradictory and (2) that atheism (whether materialist or platonic pluralism) provides the necessary and coherent conditions for all of human experience -- including intelligible accounts of possibility of knowledge and existence of moral absolutes.  This, of course, is something that neither Martin nor millennia of failed atheist philosophy and science has done.  In short,  TANG is not a transcendental argument and Michael Martin does not understand transcendental argumentation (at least, he fails to understand TAG).  ^↩

More on TAG

A correspondent has asked, "Is 'logic' a premise of TAG (The Transcendental Argument for God)?"¹

This question underscores the typical unbeliever's inability to grasp the issues in the debate between totally antithetical worldviews. It also suggests a general unfamiliarity with transcendental argumentation -- as it construes TAG as a deductive argument, and it seems to lapse into a standard "deductivist" view of proof, so prevalent among many unbelievers.

First, TAG is not formally a deductive argument. Deductive arguments necessarily presuppose logic. Without logic, deductive arguments could not even get off the ground. So, the answer is, no, logic per se is not a premise of TAG.² In the presuppositional defense of Christianity, we do not presuppose a merely abstract and autonomous logic, nor do we posit it as a premise of a deductive argument leading to a conclusion of a God of indeterminate character or an abstract "God of the philosophers."

Second, when it comes to the issues of the existence of logic, abstract objects, and conceptual reasoning, in general, the point of TAG is that the godless reality of atheism, on the basis of its own metaphysical presuppositions, cannot account for their existence. For instance, the existence of logic and material monism are contradictory. Laws of matter and the ultimacy of chance do not produce mentally free, conscious beings who are capable of abstract thought. Materialism cannot account for the existence of immaterial abstract entities of any type (be it logic, mathematics, or moral laws).³ The existence of logic, then, is a problem, and failure, of the atheist worldview. As I have written before, atheists cannot give a "reason for reason." As such, atheists have no metaphysical ground for their presupposition of logic. Atheists, being "epistemological loafers" as Van Til put it, will not acknowledge this. Even in the face of continued prodding, they continue to use a merely assumed autonomous logic and reason, that is, just "take it for granted." But that is question begging and an intellectually empty response. Yet, on the other hand, they will assert that man and his mind was produced by (and thereby, still ruled by) ultimately random material processes. Atheism -- by asserting the autonomy of man (and thereby, the ultimacy of the human mind) along with the ultimately chance nature of temporal facts -- is self-contradictory. Atheism provides no grounds for any of its beliefs (articles of faith, as it were); it can only be adhered to by a willful intellectual blindness.

The positive presupposition of TAG is the existence of the Triune God of Christianity who has revealed Himself in the Bible, in nature, and within man himself. God is the metaphysical ground from which all human experience is intelligible. Logic (and other abstract objects) is not a problem for the Christian theist. Behind man's reasoning is the mind of God.

To reiterate the point: logic is a problem for atheists and agnostics; it is no problem for the Christian theist.

In response to the correspondent's question, I pointed out the following as an example of presuppositions: The laws of logic are laws of rational thought; as such logic presupposes a thinking mind. In Christian theism, that ultimate mind is the mind of the eternal and personal God. Though this may be wrongly interpreted as if it were a deductive argument, it is not. It is an illustration of a presupposition that underlies and is the metaphysical ground of human logic.

The correspondent responded with the question, "Why can't that mind be mine?" Indeed, that is the question for him to answer based on a presumed godless reality! Many questions come to mind. For example, where or from what did his mind originate? Did immaterial minds irrationally spring forth de novo from matter in motion (If indeed there be minds as opposed to mere physically determined material brains)? Was there a first mind? Or, is there an infinite past of finite individual minds begetting new minds, (coming into being at birth, then vanishing into nothingness at death)? Is his mind ultimate? If not, what produced his mind? Is his mind free from physical determination (i.e., does he have rational freedom and volition)? How many unrelated (material and perhaps non-material) causal principles does the unbeliever invent to account for the existence of minds? Are those causal properties, along with matter and minds, of which they are properties, eternal, uncreated, ultimate constituents of reality?  In addition, for a materialist the question is (a) how all the biochemistry going on in every human skull (different processes in different locations) gives rise to objective non-material abstractions, such as logic, or, if not a materialist, (b) from whence all these contingent minds emerged equipped with innate and invariant logic. Those are just a few problems for starters.

Again, the question remains for atheists and agnostics to answer on the foundation of their metaphysical presuppositions. Answers that millennia of atheist philosophies have failed to supply.

I've already given the Christian answer: Mind is not his alone. The ultimate mind is the mind of the eternal God of Christian theism.

1 The historical connection of logic to TAG stems from Greg Bahnsen's use of the presuppositional apologetic in his debate with atheist Gordon Stein where Stein couldn't support the existence of, or use and reliability of, logic on the basis of his materialism. This was a defining moment for public awareness of presuppositionalism. In a way, it is a bit unfortunate that the debate paved the way for some, including Christians, to think that the existence of logic is the only or main element of TAG (thereby focusing attention mainly on logic in conjunction with TAG). But such is not the case. TAGs challenge to unbelief is that it cannot make sense (on its own presuppositions) of any fact of human experience. Thus, one can start with logic, or language, or mathematics or moral laws (among others) to expose the unbeliever's internal contradictions and refute the unbeliever's worldview or total view of reality. ^↩

2 What is at issue in the debate between Christians and unbelievers is not merely "logic," but the conception of logic that each participant in the debate holds. Logical reasoning is necessary -- for both parties -- in the encounter of belief with unbelief. When we reason with unbelievers we, of course, employ our God-given capacity for logical thinking. The unbeliever will likewise employ logic in the debate while all along denying God. However, the unbeliever typically does not question his capacity to reason, nor ask what is the metaphysical ground of the human ability to think and reason according to abstract laws of logic. The "logic" to which the unbeliever appeals (and which is his ultimate authority) is an autonomous "logic" that exists in a void. So an appeal to a common conception of "logic" is illusory. The totally antithetical conceptions of logic (among a host of other things) are at the core of the debate. Van Til addresses this issue:

"It appears then that if there is to be any intelligible encounter between the Christian and the non-Christian, it must be in terms of the two mutually exclusive visions that each entertains. To appeal to the law of contradiction and/or to facts or to a combination of these apart from the relation that these sustain to the totality-vision of either, the believer or the unbeliever, is to beat the air. It is well to say that he who would reason must presuppose the validity of the laws of logic. But if we say nothing more basic than this, then we are still beating the air. The ultimate question deals with the foundation of the validity of the laws of logic. We have not reached bottom until we have seen that every logical activity in which any man engages is in the service of his totality-vision." (Emph. added) Cornelius Van Til, The Case for Calvinism. The Presbyterian and Reformed Publishing Company: Philadelphia, 1964. (Quoted from The Works of Cornelius Van Til, Logos Digital Edition).

As to the question of logic in the debate between totally antithetical worldviews Bahnsen writes:

"The antithesis (in principle) between the philosophical systems of unbelievers and the philosophical system of believers is so broad and basic that it even affects the way they deal with central philosophical notions like logic, possibility, and objectivity (to mention but a few). This observation should not be misunderstood. The presuppositionalist does not say that Christians and non-Christians inevitably accept and operate with completely different, specific laws of logic in their practical exercises of reasoning. Yet they do clearly disagree with each other concerning the nature, source, and authority of the laws of logic. Both worldviews may endorse and utilize the disjunctive syllogism or De Morgan's theorems, but when we inquire into what they are talking about, the evidence that is appropriate or persuasive for their claims (about syllogisms, theorems, etc.), or the necessity of the truths about logic, we get radically different answers -- which almost always betray differing convictions regarding metaphysics." (Greg Bahnsen, Van Til's Apologetic: Readings and Analysis, The Presbyterian and Reformed Publishing Company: Philadelphia, 1998. p. 280)^↩

3 It is true that there are some atheists who are not material monists -- but they are few and far between. There are idealistic monists (mind is the fundamental stuff of reality) and there are others usually referred to as "pluralists" who believe in a plurality of co-ultimate things (Roger Penrose, for example). But, in the case of the pluralists, merely asserting the existence of minds and a plurality of immaterial "platonic" entities with no coherent unity among them is question begging and provides no intelligible ground for human knowledge. In addition to being no answer to the problem of the one and the many, no atheist has given the account of what bridges the gap between the particulars of the atheist's material world with its basic chance characteristics and their eternal unchanging realm of universal "platonic" entities. As mentioned above, the existence of human minds in this worldview is also a major problem -- especially on the macro evolutionary account that human minds are no more than material brains assembled by (and thereby still controlled by) random physical processes. The dual atheist principles of human autonomy and the ultimacy of chance are contradictory.

The many problems of a platonistic conception of reality are well known, which explains why few advocate it, and won't be dealt with here. As to the idealists, which were more in vogue during Van Til's time, Van Til's writings, in particular A Survey of Christian Epistemology, provide a wealth of information on the internal contradictions of the idealists. ^↩

Conversations with Atheist Unbelievers

"For we must all appear before the judgment seat of Christ; that every one may receive the things done in his body, according to that he hath done, whether it be good or bad.  Knowing therefore the terror of the Lord, we persuade men;" (2 Cor. 5:10-11a)

In our apologetic endeavors in conversation with unbelievers, we both defend the faith and proclaim the truth of God to lost souls. The true situation is that we are both creatures of God and that the unbeliever is in need of a Savior. The conversation is meaningful, rational and intelligible.

To the atheist unbeliever, we are all matter-in-motion, assembled by chance, a mere piece of the universe, yet (somehow) free from the universe -- in need of nothing. In this case, the conversation would be meaningless and unintelligible.

Our apologetic is built on the fact that we are both creatures of God, and we should not compromise this truth by way of a method that lends credence to the unbeliever's pretension to the contrary.  On the atheist's view, the fact of a rational conversation itself is inexplicable.

Remarks on Transcendental Arguments

Choosing Hats posted a link to a new web site discussing transcendental argument (TAs).  That posting, which can be found here, has prompted me to add my proverbial 2 cents to the discussion.

In reflecting on TAG (Transcendental Argument for God) and its use over the years, I have come to realize that many are unable to recognize a transcendental argument.  There are probably several reasons for this, but one reason may be that most people who have exposure to logic are reared on the classic syllogistic form. TAs are not properly syllogistic and thus cannot be written as such.  (Though syllogistic schema have been employed.)
 
Transcendental arguments have a self-reflective property.  Typically, they consist of statements for which the speaker is under pain of self contradiction when uttered.  Some perennial examples are the so-called liar's paradox: "I always lie."  That statement, if true, would necessarily be false, and so it must be false.  The person speaking such is a liar -- just not a constant one!  Another example, pronounced a few months ago by my favorite agnostic, is: "There are no answers to Big Questions." That statement is an answer to a "Big Question," and thus self-refuting.   Finally, Descartes' dictum, "I think, therefore I am" is, in my mind, more forceful when stated transcendentally as,"I don't exist" --  a blatant self-contradiction.

The above TAs I will call "first-order" transcendental arguments, since they consist of statements that are directly self-referencing and self-refuting.   This type of argument is sometimes called "retortion."   TAs were recognized as destructing the very foundations of Logical Positivism which scoffed at "metaphysical" inquiry (one should raise an eyebrow immediately) and tried to base its epistemology (without metaphysics!) on the premise that all truth is either empirical or logically derived (i.e., tautology).   All else was metaphysical nonsense. The problem, of course, is that the foundational premise of Logical Positivism is neither a tautology nor an empirical truth.  Thus, Logical Positivism is metaphysical nonsense of the very sort they decried.  

Let's consider TAG.  In a nutshell, TAG is the statement that "There is no God" is self-refuting.  This is not direct retortion since it is not directly self-refuting, but the unbeliever carries a host of beliefs that would only be true in the Christian worldview, and thus when he utters "there is no God," he should abandon any of his beliefs that are only true in Christianity.  Some examples of those beliefs would be morality, the invariant laws of logic, justice, human independence from physical determination, and so on.  The list is long.  The unbeliever's worldview is ontologically, epistemological and ethically self-contradictory.  Since the unbeliever holds to contradictory thought, his worldview is irrational.

The fact that the unbeliever adheres to belief in the concepts mentioned above is another aspect of transcendental arguments: the idea of the stolen concept.

The unbeliever rails against God using beliefs -- such as morality -- that would not exist in the atheist world.  The claim that Christianity holds to beliefs that are immoral is an old line of attack, and one which Bertrand Russell attempted in "Why I Am Not a Christian."   It is a fallacious and self-defeating argument which also has been continued by some of the "new atheists," such as Christopher Hitchens, who attempt to use the concept of "evil" to deny God.  These arguments fail because "evil" would not even exist in an atheistic world, for there would be no such thing (!). As Bahnsen pointed out against Russell's "Why I Am Not a Christian" (and which holds equally against Hitchens et al.):

     "On what basis, then, could Russell issue his moral evaluations and judgments? In terms of what view of reality and knowledge did he assume that there was anything like an objective criterion of morality by which to find Christ, Christians, and the church lacking? 

       Russell was embarrassingly arbitrary in this regard. He just took it for granted, as an unargued philosophical bias, that there was a moral standard to apply, and that he could presume to be the spokesman and judge who applies it." [Always Ready, p.156]

In fact, I recently corresponded with an agnostic who railed against God because he thought it seemed "unjust" that God would send a "good" atheist to hell.  His example was an atheist who did all sorts of "good" but only failed to believe in Christ.  That example is, of course, a specious argument since it conveniently ignores the issue of the evil acts of the hypothetical perfect atheist.  But regardless of that glaring oversight, the question that must be pressed is where does an agnostic's idea or standard of absolute "good," "evil" and "justice" come from?  There simply is no such thing in the atheistic world -- they are "stolen" concepts (or as Van Til said, "the borrowed capital of Christian theism") and thus that argument fails!

Then we have the case of Prof. William Provine, a material monist, who thinks he is "rationally" asserting that there is no human free will. Provine, as I previously pointed out, is consistent with his material monism when he reasons that human beings -- being no more than physical systems propelled by inviolable physical forces --  cannot be autonomous.  Yet, rationality presupposes freedom to be guided by violable laws of logic.   We have the picture of irrational physical forces compelling  "free" and "rational" actions -- actions that Provine has claimed are not possible!  Thus, Provine is self-refuting by way of a TA.  

I recently discovered that Epicurus stated the original transcendental refutation of Provine many years ago. Epicurus stated that one cannot rationally deny free will, since rationality (i.e., adherence to laws of logic) presupposes free will.  The argument as stated on the Internet Encyclopedia of Philosophy ( link) is:

"Transcendental arguments can be characterized as demonstrations that the skeptic’s articulation of her own position is self-defeating in some way. These arguments imply that the skeptic cannot even coherently articulate a given position. Epicurus is reported to have argued that, without free choice, one assents to propositions only because one is determined to do so. Without free choice, then, it would be impossible to rationally assent to any proposition—that is, to assent to it because one has good reasons to think it is true, rather than because one must. The proposition that one has no free choice is thus self-stultifying, in that, if true, it cannot be warranted. This reasoning implies the following argument:

    (1) I am able to rationally assent to the proposition that there is no free choice.
    (2) I could not rationally assent to any proposition if there were no free choice.
    (3) Hence, there is free choice."

"That which cannot be true, must be false," and that is exactly what atheism is!  It asserts an impossibility.  It is a world that fails ontologically, ethically, and epistemologically. It is a world without rationality, ethics, or human freedom, yet the atheist presupposes such must be.  And since atheism is impossible, then agnosticism, too, is untenable.  The agnostic should immediately abandon his skepticism regarding God, since the skeptical agnostic essentially asserts that God's existence is unknowable and, thereby, it is possible that there is no God.  We might wonder just what metaphysical law of "possibility" exists that would demand such! If the only possibilities are dictated by the physics of material monism, then one has a most baldly vicious circular argument.

We also have the skeptic.  The global skeptic claims "nothing is knowable," and as shown above, he has been summarily defeated by a first-order transcendental argument. "I don't know anything" is refuted by the unintelligibility of the utterance.  So, what we really have is the relentless unbeliever who doubts everything except the power of his autonomous reason from which he launches his skeptical attacks.  He ought to wonder why his own reason is immune (!), and if he will admit that it is not, he ought to wonder why he busies himself with his skeptical arguments against Christian theism, all the while acting as if "his" reason is the ultimate authority!  In the last case, we see another person who should shut his mouth.  The fact that he does not is a testimony to foolish pride of the agnostic's heart and his reliance on his supposed self-sufficient autonomy.

In summary, all unbelievers have a prideful, irrational adherence to the power of their own autonomy and their autonomous reason. But such autonomous rationality would not exist in a reality wherein all acts are no more than the compelled effects of ultimate irrational quantum mechanical chance events. According to the atheist, man himself is nothing more than a manifestation of that ultimate irrationality and, thereby, the metaphysical equivalent of "sock puppets."

TAG at 25

As 2010 draws to a close, it seems hard to believe that it has been 25 years since Greg Bahnsen’s presuppositional apologetic first laid waste to atheistic philosophy in his debate with Gordon Stein. It was in that debate that Bahnsen referred to Van Til’s presuppositional approach as the "Transcendental Argument for God" or TAG.  The short sloganized version of the argument is Van Til’s statement that the Christian God exists because of the impossibility of the contrary.

Since that time there has been plenty written about TAG – a lot of it more noise and confusion based on a total misapprehension of the issues involved in the argument. To understate it, TAG is misunderstood by many. In fact, a lot of the noise surrounding TAG has come from Christian apologists of the so-called “classical” and "evidentialist" schools of apologetics. The most frequent of these charges is that TAG is circular. As well, this is a charge that occasionally comes from the man-in-the-street as a first-blush objection.

To dispel the mistaken charge of circularity, we should note first that historically Bahnsen’s debate opponents, Gordon Stein and Michael Martin, never made such a charge. Stein, for one, realized he had no answer to TAG and after the debate stated that he was working on a rebuttal; Stein never published a rebuttal. If the rebuttal were that TAG was circular, it is rather remarkable that an educated and intelligent man such as Stein never produced it. Then there is the professional philosopher, Michael Martin.  Martin has not charged TAG with circularity. If it were, Martin, too, would have had no problem producing the proof of circularity.

An oft-quoted aphorism states that imitation is the sincerest form of flattery. Martin, in fact, attempted to mimic TAG with his failed TANG (Transcendental Argument for the Non-existence of God). TANG, though not properly transcendental, attempted to be – and, as such, is a testament that Martin clearly understood the issues involved in TAG and recognized TAG’s power. But TANG, as Martin stated it, is intended to be a “counterexample” to TAG that thereby “logically” establishes that TAG is unsound. Therein lies the rub. Providing a supposed counterexample is not a transcendental refutation and is rather simply a restatement of an opposing worldview. To construct a transcendental argument, we must ask what are the contents of a worldview, and are they coherent, intelligible and not self-contradictory or self-refuting? In short, do they withstand the transcendental critique of being internally consistent (non-self contradictory) and non-arbitrary. Indeed Martin's worldview contents do not!  In fact the pluralistic godless world of Martin's TANG describes an impossible world which, in turn, proves God's existence!

In Martin’s case, his worldview is atheistic pluralism which he posits as the “necessary preconditions” for the non-existence of God. Of course, if God does not exist, he has no properties whatsoever (or whatever properties Martin wants God to have so that he would not exist under the postulates of his atheistic pluralism). The co-ultimate components of Martin’s pluralistic universe are nature, logic and morality. The God Martin describes in TANG is like one who awoke after an eternal nap and discovered himself surrounded by nature, logic and morality. In other words, physics, logic and morality are all ultimate and God is not. Such a God is not the God of Christian theism. The God of Christian theism is the ultimate being – and He is as He has revealed himself. To construct a counterexample based on a being who is not ultimate is simply a straw man, a logical fallacy, and misrepresents Bahnsen's point. So much for TANG being a counterexample to TAG and invalidating TAG!

So in the end, we have that TAG is not circular in the trivial manner that is charged – and this from the examples of atheists of repute among atheists.

What still remains then is the challenge of TAG to unbelievers, such as Martin, who merely posit the existence of one or more of the eternal uniformity of nature, morality, and abstract realities such as logic and mathematics. This is an incoherent mix of eternal impersonal ultimate things with no essential relation to each other. (And this does not include the additional challenge against the metaphysical irrationalism of the atheistic interpretation of quantum mechanics which calls into question any ultimate uniformity of the physical universe.)   Martin's incoherent mixture multiplies unrelated particulars and compounds unexplained irrational mysteries (for example, what is the source or basis of interactions between, physics, logic, and moral laws?).  On top of all this are the internal contradictions that spring from this mixture of "co-ultimates."

Since Martin is unable to provide an intelligible account of his absolutely independent and non-interacting eternal brute facts, he is unable to argue against Christianity on any ground whatsoever – whether it be morality, science, or logic.

For one example, Martin wants to appeal to “abstract logic” in TANG. But logic is a formalization of laws of thought -- that is of valid deduction -- and as such, logic presupposes a mind, and then a thinking being.  To postulate eternal mindless laws of thought is an absurdity.  But Martin doesn’t tell us where, when or how a mind came into being, whether there was always a mind (an eternal personal mind is something that is too close to theism for him, no doubt) or that it was born from matter-in-motion.

If Martin appeals to reality as just eternal matter and that the laws of physics are just expressions of the inherent properties of matter, one should see that the laws of logic are not inherent properties of matter. And if minds sprang out of matter, they are not free, and rather are always subject to the laws of physics – laws of thought nowhere enter the picture.

Without human free agency, one cannot provide an account of how matter obeying physical laws can generate actions that appear to conform to laws of logic, such as modus ponens, as just one example.  If someone would violate a law of logic in an argument and reach a false conclusion (compelled by physics, of course) it would be ridiculous to say the laws of physics were in error.  But such is one of the many contradictions of atheism.  Atheism is still transcendentally refuted by TAG.

An Atheist's Miracle

The miraculous is the suspension or violation of natural laws.    For Christians,  miracles are the result of the supernatural agency of God.  It should go without saying that atheists of the material monist variety -- for which all that exists are material systems obeying natural laws -- deny miracles.  Prominent examples are Richard Dawkins, Christopher Hitchens and the recently discussed William Provine.

Here, we want to examine the atheism of Richard Dawkins.   Dawkins describes himself as a "dyed-in-the-wool monist."  A monist believes there are no "minds," just physical brains, and much like a computer, there are "brain states."  Man, being a purely physical system, must always be subject to purely natural laws.  The brain, too, is a physical system, controlled by the underlying natural laws -- thought being a mere passive epiphenomenon, with no causal agency.   It is a theorem of this worldview then, that man, as such,  cannot be free from natural laws, and, thus, there can be no human freedom.   William Provine can see this easily (as he has said), and -- as an almost-consistent naturalist --  asserts the absence of "free will." To deny this conclusion is to accept a supernatural suspension of natural law -- a miracle -- which Provine, consistent with his unadulterated material monism, rejects.

Which brings us to Richard Dawkins, who says:

"I am very comfortable with the idea that we can override biology with free will. Indeed, I encourage people all the time to do it."  (Counterbalance Foundation Interview) 

What we have here is an unabashed atheist miracle.  After millennia of being subject to physical causation, a physical system called "man" evolved by natural law and then spontaneously broke the shackles of natural law, violated the natural laws, thereby becoming henceforth "free."   Man's brain also became "free" to employ abstract (non-physical) logical principles and to reason.  This is an absurd and irrational miracle.   Dawkins can override biology at will and encourage others to do so, too.   Quite a miracle -- a physical system violating physical laws every second of every day.

Christian miracles are intelligible since God, the rational Being who created and upholds natural law, can intercede according to His will.  Likewise, Christians as dualists (man has both a material body and an immaterial soul), deny man is causally determined by physics.  So then, belief in Christian miracles is rational. . .Dawkins' belief in his atheist miracle of "free will" is irrational.

Richard Dawkins describes Christians as "dyed-in-the-wool-faith-heads" who are "immune to argument." He could not be more wrong -- Dawkins the self-styled "dyed-in-the-wool monist " with a belief that a natural system called man can override biology (which is just physics, after all)  is the one immune to reason.  Dawkins' faith in his atheist creed makes him a "dyed-in-the-wool-faith-head."  He will accept an irrational atheist "miracle," but deny the rational Christian miracles.

And to think Dawkins subtitled his website "...Reason and Science,  A Clear-Thinking Oasis."  Contrary to that slogan, Richard Dawkins is a most muddle-minded irrational "scientist," and that is saying a lot.
