The post I’m about to respond to came in on my google alerts today. It was so packed with common objections and misconceptions that I decided to answer.
Evidentialism v. Presuppositionalism
I have noticed a worrying trend among some Christians. It is the turn away from evidentialist apologetics toward presuppositionalist apologetics.
Let’s start our presuppositional examination right here. From the get-go, presup is a “worrying” trend. Second, the author is apparently unaware of the link between Sola Scriptura and Covenantal apologetics. As I have said quite often on this blog, and in our chat channel, Covenantal apologetics is Sola Scriptura in an apologetic context.
Evidentialism holds that belief should rest on evidence.
Presuppositionalism holds that belief rests on presuppositions.
What would have been both accurate and useful would be to explain what we do believe about evidence, and to cite something, anything, from the primary sources concerning what the actual discussion hinges on. Namely, that your presuppositional commitments determine both what is considered to be evidence, and how this evidence is interpreted. This is a common problem with evidentialist and unbelieving critiques. For instance: “Nor can we disagree with [Warfield] when he says that the Christian faith is not a blind faith but is faith based on evidence.”  “I see induction and analytical reasoning as part of one process of interpretation. I would therefore engage in historical apologetics. (I do not personally do a great deal of this because my colleagues in the other departments of the Seminary in which I teach are doing it better than I could do it.) Every bit of historical investigation, whether it be in the directly biblical field, archaeology, or in general history, is bound to confirm the truth of the claims of the Christian position. But I would not talk endlessly about facts and more facts without challenging the unbeliever’s philosophy of fact. A really fruitful historical apologetic argues that every fact is and must be such as proves the truth of the Christian position. 
Evidentialist apologetics attempts to bring converts by revealing the evidence behind Christianity. Evidentialists say that scientific evidence actually supports Young Earth Creationism, that archeology has proven the truth of the Bible, both new testament and old, and that the evidence for Christ’s historic existence is overwhelming.
I would simply point out that vanishingly few evidentialists argue for YEC at this point in time. Further, they would not argue that it was “proven”, but that there is a greater probability for the truth of the Bible and/or Christ’s historic existence, as a rule. I would humbly submit to you that their “philosophy of fact”, as Van Til would say, has brought them to this point.
Presuppositionalist apologetics attempts to bring coverts by arguing that the only rational, coherent worldview is that which begins by presupposing the divinity of the Bible, the existence of God, and the reality of Christ’s sacrifice. In other words, presuppositionalists say that one must presuppose Christianity, and that trying to convince someone based on evidence is flawed.
We don’t argue for the “divinity” of the Bible. We don’t believe in a quadrinity, a la Fristianity. We don’t argue that the Bible is equal to Christ, as the Word, either. One must presuppose Christianity to be making an intelligible argument, obviously; but it might behoove the author to do a bit more research into what exactly is being said on this point. If the author means “convincing someone based on evidence” as if “evidence” was something everyone agreed upon, as if it was some sort of neutral ground, sure. Obviously, Scripture says that we and world consider each other to be foolish. It’s hardly the case that we should be expected to see eye to eye on what is, or is not, “the facts”. Hence, Van Til’s discussion of “brute fact”, which the author would be well-served to study, in my humble opinion. We don’t “attempt to bring converts” by this method. We, after all, are Reformed. As such, we are divine monergists, not synergists or human monergists, so conversion is quite obviously the work of the Holy Spirit in regeneration, according to election. Neither “the facts” nor a transcendental argument will save – God saves, not man. Sure, they won’t hear without a preacher – but as the name “Yeshua” points out, salvation is of the Lord.
Evidentialist apologetics is traditionally associated with evangelicalism and fundamentalism while presuppositionalist apologetics is associated with more reformed traditions. This actually makes a lot of sense given that arminianism emphasizes free will while calvinism emphasizes predestination. It also makes sense given that Cornelius Van Til and Francis Schaeffer, both reformed, are the major luminaries who developed presuppositionalist apologetics. More and more these days this approach is spreading beyond reformed circles and into evangelicalism and fundamentalism in general.
Actually, evidentialism initially comes from Romanism, as has been carried along with the rest of the Romanist doctrine still held to by Arminianism and general Evangelicalism (to include the modern fundamentalist movement). I’d invite the author and her readers to take a gander at classical Thomism, and see what exactly the difference is supposed to be. The Reformation, of course, was a movement to “restore” Christianity. To restore it back to its historical orthodoxy. A walk back through history, and through the development of the doctrine of Sola Scriptura, will show the intrinsic link between a practical use of Sola Scriptura and a presuppositional methodology. Van Til’s contribution to “Semper Reformanda” was the Reformation of apologetic methodology to the principle of Sola Scriptura. This understanding is positively vital to understand what is actually being said, and what it comes from. Most objections along these lines are not truly to presuppositional methodology; but to the doctrine of Sola Scriptura. To answer these objections, and to accurately make objections in the first place, requires an understanding of this, and the proper relationship to be found there. General evangelicalism is attracted to covenantal apologetics in spite of itself, to be frank. The methodology does not lend itself to an Arminian, Romanist, or Dispensational hermeneutic. There are too many preconditions that are simply missing for it to be consistently and coherently used. As such, there will be a host of problems in execution, principle, understanding, and doctrinal compatibility that kill the method aborning, if you try to adapt it in some way. This is not to say that every group listed above is equally inconsistent, or that every individual is equally inconsistent; however, there is a specific doctrinal basis that it springs from, and without which, it simply does not have the framework in which to operate. Those varying inconsistencies crop up at various and sundry points – but keep in mind, please, that a truly Covenantal apologetic argues on the level of worldviews – and that it argues all of Christianity versus its antithesis; and that part of that expression of Christianity plainly states that there are but two worldviews.
I was raised on evidentialist apologetics (not surprising given that my parents were strong arminians). My parents were fond of telling the story of Josh McDowell, who started out as an atheist attempting to disprove the truth of Christianity and ended up concluding, based on evidence, that Christianity was actually true. I was taught to follow the evidence, and assured that evidence led directly to Christ.
This is actually fairly typical. Note, however, that there is usually a decided de-emphasis on the work of the Spirit in the use and presentation of evidence (not to mention the philosophy of evidence) in this apologetic methodology. Let’s be frank. If the Spirit is mentioned at all, it’s usually in a touchy-feely “invitation” at the end, after God is “proven” by means of “higher probability”. What the Spirit’s work is, as stated in Scripture, is practically never mentioned, and if it is, it bears practically no resemblance to the Scriptural testimony. The emphasis is more likely on the target’s will, and intellect – and practically never on that same person’s moral guilt before the holy God, which both affects and taints everything about that will and intellect. On the contrary, Reformed doctrine requires that the unbeliever be confronted with their sinfulness before God and their inability to reason, will, or act in any righteousness before God whatsoever. This is a confrontation that is just as much evangelical as it is apologetical. They are, after all, two sides of the same coin. The emphasis in evidentialism and evangelical doctrine, rather than on the Triune God’s monergistic work of salvation – in election, atonement, and regeneration – is on the synergistic work of man in reasoning, willing, and acting rightly of themselves, to “meet God” in the middle.
Having been raised on evidentialist apologetics, when I arrived at college and found new evidence I had never heard of as a child, I didn’t simply reject that evidence. Instead, I researched and read and studied and reevaluated my beliefs based on new evidence. I found, for example, that the evidence does not actually indicate that Young Earth Creationism took place (quite the opposite), that archeology has actually contradicted the Bible in many places, and that the Bible actually does contain historical errors and contradictions. This process of reevaluation started a long spiritual journey, and even today I continue to strive to follow evidence, and I work to make sure I take into account any new evidence I encounter.
In other words, having been raised in evidentialism, and the freewheeling doctrinal imprecision of arminian/evangelical churches, the author was never taught to 1) Think Biblically or 2) Think about what “evidence” means, or is predicated on. Since “evidence” is considered to be a neutral ground between believer and unbeliever upon which we have a point of contact, and since she was never taught how to deal with evidences on the level of their presuppositional commitments, she was caught between a rock and a hard place. If you are stuck between fundamentalist evangelicals and fundamentalist secularists, you will be either be grist for the mill, or “bail” in one direction or the other on any given “fact” that is presented. The “fact”, or how it is presented and interpreted, is never really examined. It “just is”, as if it is on the level of the self-existent God. Instead of interpreting “the facts” through Biblical presuppositions, “the facts” are, in reality, being interpreted through secular presuppositions that state that it is flatly impossible that the world could have come into being as the Bible said it did. If we are never taught to “dig beneath” the level of “brute fact”, we are simply fodder for the antithetical worldview, raised against the knowledge of God. “Striving to follow evidence”, then, is mere slavish adherence to secularist presuppositions concerning the nature and meaning of evidence.
The goal of evidentialist apologetics is to convince others of the truth of Christianity by using evidence. It assumes that anyone who honestly looks at the facts will arrive at the truth of Christianity, and that the facts support the truth of Christianity. In the last few years, my parents have been moving toward presuppositionalism. This makes sense, given that the evidentialist approach actually led me away from their beliefs and that Vision Forum is actually openly and proudly presuppositionalist.
The first two sentences are a more or less accurate restatement of evidentialism. The second two are more or less well-poisoning concerning presuppositionalism. Let’s notice two things about the former. First, she is talking about persuasion, not proof. As we’ve already mentioned, there’s a doctrinal divide there. Persuasion, in Reformed doctrine, comes only when the regenerate encounter the truths of Scripture, and believe them as it is given them to do so. This is separate from proof, which also has a fundamental divide in view. For the Christian, apart from the Triune God of Scripture, you can’t prove anything. For the non-Christian, proof is determined by their own presuppositional commitments as to what a valid “proof” consists of. Secondly, it is “assumed” that a) anyone who b) honestly looks at c) the facts will arrive at the truth of Christianity, and that those facts support the truth of Christianity. Let’s look at a) for a moment.
First, there is a lack of any sort of Biblical notion of election, or division between sheep or goats, or the effects of sin, or of the necessity for regeneration. This is a doctrinal issue, at base. Let’s look at b). Arminianism, following Romanism, considers men to be able to choose good, to be intellectually honest, or to act in such a way as to properly respond to the truths of God – of themselves. This is vastly different from the historical orthodoxy the Reformation sought to return to, following Scripture, which teaches that men, in and of themselves, are evil, and they do the work of their master, Satan. They are slaves to sin, and unable to break those chains. Only the regeneration of the Spirit can break those chains, given men a new heart and mind, and give them the faith which which they believe the Gospel. This is a fundamental disconnect, and cannot be overemphasized. As for c), we simply point out that God is truly and exhaustively Sovereign. This is also a fundamental disconnect from the insistence on libertarian free will that stems from Romanist/Arminian/Evangelical doctrine. I’d also point out that it differs not a whit from the insistence of the world on their own self-determination in the realm of the intellect, the will, and their own actions. This is also a doctrinal issue. As Reformed believers, we stress, with much insistence, the Biblical testimony to the exhaustive sovereignty of God over all things whatsoever that come to pass. Given this doctrine, all facts are God’s facts. I’ll repeat this; All facts are God’s facts. If all facts are truly God’s facts; if God ordains both ends and means, and every single relationship thereof, in a truly exhaustive fashion, then there is no room for “the facts” as they are presented to us by the Evangelical/Secularist position. All facts are, given what God has revealed to us in His Word, guaranteed to us by His Spirit, and shown to us in ourselves, and in the creation surrounding us, actually evidence for the truth of Christianity. It is not neutral evidence. It is a hostile witness against a rebellious subject.
Presuppositionalism argues that the evidence we experience in the world is simply facts and pieces of data that must be interpreted through an interpretive framework, or worldview, and that the only way to consistently interpret these facts is through the Christian worldview.
The first part is wrong; the second part is right. Here’s why, and it will be expanded below. It ignores that “all facts are God’s facts”, as we just explained. As she will say below, she assumes exactly the opposite of what we believe, and inserts that in our position. It is not the case that “facts and pieces of data” are “simply” that, and merely need to be “interpreted” – it is actually the case that the only framework through which facts are even intelligible is that which is revealed to us by the ordainer and the creator of all that is to be filtered through that framework, and of the framework itself. Facts are not neutral.
In other words, a person looking at facts and evidence will not necessarily be led to Christ; rather, one must start by assuming the truth of the Bible in order to find Christ. You can see the influence of calvinism here. Presuppositionalist apologetics, then, focuses on pointing out inconsistencies of other worldviews and arguing that Christianity is the only coherent worldview, the only way to explain the existence of reason and logic. In fact, presuppositionalism literally goes so far as to argue that evidence-based apologetics – as opposed to apologetics based on contrasting worldviews – is contra-Biblical.
Actually, we go quite a bit farther. The Shepherd finds His sheep – we don’t “find” Him, because we aren’t the One looking. Yes, Calvinism is in view here, but I’m not sure how much the author really has studied Calvinism as a complete system. The point isn’t that we “assume the truth of the Bible to find Christ” – it’s that the Spirit’s regenerative work, and the gift of faith and repentance are the preconditions for our salvation; that the work of Christ in His atoning work for His people propitiates the just wrath of the Father, and that the electing grace of the Father, who draws men to Christ is the precondition for it all. In short, it’s not anywhere near this simplistic presentation. The Spirit grants us faith – and the new heart and mind to accompany it, so we believe and/or trust the Author of Scripture as we ought. The focus of Covenantal apologetics is two-fold, actually, not singular. It “pushes the antithesis” between Christianity and it’s opposite, to show that a) Christianity, as revealed by the Creator of all things, is the sole possible precondition for the intelligibility of all things; and b) that it’s opposite is impossible. It’s a two-step method, not a one-step method. “The first step is to lay out the Christian worldview in terms of which human experience is intelligible and the objection of the unbeliever can be contextually defeated. The second step is to show that within the unbeliever’s worldview, nothing is intelligible – not even objections to the Christian’s viewpoint.”
Presuppositionalists don’t deal with evidence, because they argue that evidence and facts are neutral and can be used to support any worldview, because they are interpreted through that worldview’s lens. In other words, if someone presupposes a world without God, that’s what they’ll see; if someone presupposes a Christian world, that’s what they’ll see; if someone presupposes a Muslim world, that’s what they’ll see; etc. That is why presuppositionalists spend their time not on the evidence but rather on trying to show that their worldview is only rational, coherent worldview in existence, and that every other worldview is internally contradictory. Evidence doesn’t matter; what one chooses to believe is what matters.
This is catastrophically wrong. It is absolutely opposite to what we believe, in fact. First, I categorically deny that evidence and facts are neutral. In fact, I have specifically stated that they are not. On every single point the Christian and non-Christian are fundamentally at odds. There is no point in our respective worldviews where we have any neutral ground whatsoever. If that isn’t clear enough, I’ll spend as much time as it takes to make it clear. This statement is absolutely, unequivocally false. There are two worldviews, and they take antithetical positions on every fact whatsoever. It is the case that facts are not neutral, and can only be intelligible when the Christian worldview is presupposed. It is not the case that facts are neutral and can be interpreted differently, depending on which worldview you happen to hold. Additionally, please take note of the usage of “worldview” here. I have said, several times, that we believe there are two worldviews. We are not saying that there are three, or any higher number. There are two, and only two. There are many practically inconsistent variations of the non-Christian worldview; just as there are inconsistencies in the Christian worldview of many actual (or putative) Christians. Yet, there are only two worldviews. I’ll leave you to research the principle/practice dichotomy Van Til presents.
We don’t spend our time on “trying to show that their worldview is only rational, coherent worldview in existence, and that every other worldview is internally contradictory” because “evidence doesn’t matter”; we spend time proving that the Christian worldview is the only possible worldview by demonstrating that the contrary worldview is impossible – it does not provide the preconditions for intelligibility. We do this because it is actually the case that the non-Christian worldview does not provide those preconditions. Not because “evidence doesn’t matter” – but because evidence is unintelligible unless our worldview is presupposed. The last sentence is the real problem with the author’s view of presuppositionalism. “What one chooses to believe” is predicated on what you presuppose. What you presuppose is directly consonant with whether you are regenerate, or unregenerate. It is that clear cut. Are you a “slave to sin” or are you “Christ’s slave”?
The problem with these people is that you can’t argue with them. They’re going to believe it because they believe it, and nothing else matters. As an example, Answers in Genesis, a Young Earth Creationist group that runs the Creationist Museum in Kentucky and has recently embraced presuppositional apologetics wholeheartedly, is actually completely open about the fact that it simply rejects evidence that contradicts their interpretation of the Biblical account of creation. It’s not about the evidence. It’s about the presupposition. And no matter what you say, you’re not going to change their minds.
“These people” seems to indicate what the author thinks of those who adhere to this method. Instructive, indeed. Far from not being argued with, I can personally attest to the fact that I am argued with constantly by objections from unbelievers as well as putative believers. Once again, the distinction between persuasion and proof is not being addressed. An argument is a proof. Acceptance of it as true is persuasion. It is not that they “can’t argue with these people” – it is that they a) aren’t persuading us and b) are not being persuaded. As we have already stated, this is both accounted for by the Scriptures, and expected. God changes hearts and minds, not us. As to the attempted well-poisoning concerning AiG – I’d like to present this as evidence. If the author would like to share some substantiation of their statement, I’d love to see it. My suspicion is that it is yet another example of a confusion between a) proof and persuasion or b) the author’s misunderstanding of our position concerning evidence. What the author is doing with the continual drumbeat about “evidence” is simply confusing what we actually have to say concerning evidence. It’s not simply about evidence. We have no intention of being that superficial and unreflective concerning the nature of the discussion. What we are doing, however, is addressing the philosophy of evidence along with the evidence itself. If the author would like to show how she has done anything remotely similar in addressing this subject, I’d love to see it. What the author has done is to demonstrate the importance of what we are actually saying; a sort of demonstration concerning the law of unintended consequences. Unless she addresses the philosophy of evidence along with the evidence, she is simply assuming her own position vis a vis her philosophy of evidence, and demanding that others accept it. If others do not kowtow to her wishes, she dismisses them, and says “you can’t argue with these people”. “These people” would beg to differ, and would invite the author to address the philosophy of fact, or evidence, along with the facts and evidence.
Problems with presuppositionalism include:
The logic is circular: you prove something is true by assuming it is true.
Presuppositionalism could be used to “prove” any religion, or even atheism.
Please provide an example. This is another common objection, incidentally.
Just because a worldview is coherent doesn’t mean it’s true.
Who ever told you that was our argument? Again, this is a two-step method, not a one-step.
There are many things about the Christian worldview that are arguably not coherent.
This is a great example of uncritical thinking. Do we consider them to be arguable? If not, why are you begging the question in your own favor?
There are other worldviews that also explain the existence of reason and logic.
Please enlighten us 😉
You can’t actually know something is true if you simply discount evidence entirely.
Utterly false description of our position.
Finding truth involves not making presuppositions, but trying to rid yourself of them.
Start with this one, please. We don’t make presuppositions; they are revealed to us. Second, this is really, really bad.
Presuppositionalism holds that everyone starts out with assumptions, and that starting by assuming the Bible is therefore no different than what anyone else is doing. Actually, most people start out with fairly simply assumptions.
No, it doesn’t. Seriously, if you don’t even know what you’re talking about, why are you writing on the subject? That is not even remotely our position. Do you really think the Bible is no different than what anyone else is doing? Do you think any Christian does? If so, why are they Christian, then? If even a fairly liberal type doesn’t even do that, why on earth are you saying Calvinists do, of all people? I can’t believe that you thought this through especially well.
I, as an example, start out by assuming that I can trust my senses and that the world around me is something I can seek to understand. Lest a presuppositionalist argue that these are atheist or materialist assumptions, I would point out that essentially everyone starts out with these assumptions. In fact, I have never met a Christian who didn’t start out with these same assumptions. Assuming that we can trust our senses and learn about the world around us is completely different from assuming the truth and divinity of the Bible or the existence of God.
“Lest” I do or not – those aren’t materialistic assumptions. Materialistic assumptions don’t exist, as assumptions are definitionally immaterial. However, even from another perspective, they don’t belong in materialism (per se) either, because she has no reason whatsoever to trust her senses, or to assume that she should. See, she’s saying next that “we all do it” – but the real question is “what justifies it?” Starting where she starts is purely arbitrary. Second, who says that this is “completely different”? Asserting assertions assertively is not an argument, or even close to one. Plus, she is an atheist. Hence, atheistic assumptions. Is this really that hard?
I have a friend who is a presuppositionalist. I recently asked her what she would do if archaeology directly contradicted a literal reading the Old Testament (it does). She told me that it would not change anything, because she would simply assume that future archaeological finds would clear up the contradiction and line up with the Old Testament. In other words, actual evidence in the here and now does not matter, not one whit. All that matters is her assumption that the Bible is true.
Notice: Facts are once again “brute”. Her philosophy of fact isn’t even examined. Whatever it “is”, is unquestionably. (Don’t look behind that curtain, Dorothy!) I can say to her, in return, “all that matters is your assumption that the facts are true”.
But I have to ask: If you simply assume your beliefs are true and throw out any use of evidence at all, if there is no possible evidence or experience that could disprove your beliefs, how in the world can you actually know they’re true? It would be like me saying that there is an invisible pink unicorn that lives in my room. You can’t touch it or hear it or detect it with any sort of test. You’re not ever going to come to the unicorn’s existence through evidence, and you shouldn’t try to. Rather, you simply have to assume it’s there. But then, if there is no evidence for it and it can’t be disproven, how in the world do I know it’s there in the first place? I don’t: I just assume it. Wha?
This incessant drumbeat on “throwing out evidence” is key to her ideas concerning our methodology. It’s demonstrably false. If she had read any primary source materials concerning our methodology, this would be painfully obvious. Instead, we are treated to one of the most asinine comparisons we’ve ever heard from atheism. As an aside? Using secularist arguments right after you imply your distance from secularism isn’t that great a strategy.
Interestingly, this emphasis on maintaining a persuppositional worldview is is why Vision Forum and others like it see secular colleges and secular sources of knowledge as dangerous. For them, facts and evidence are not neutral, but are interpreted through an assumed worldview. Therefore, a Christian should never study under a non-Christian, because what he will be learning falsehoods, not truth. One can only learn truth by studying under other likeminded Christians. The insularity this produces is overwhelming.
