From forthcoming book Believing Bullshit. Warning: this excerpt is 7,400 words.When someone’s claim is challenged, and they find themselves struggling to come up with a rational reply, they will often say resort to saying, “Look, I just know!”
How reasonable a response is “I just know”? It depends. Sometimes, by “I just know”, people mean you should just take their word for it, perhaps because time is short and the evidence supporting their belief too complex to present in a convenient sound-bite.
Suppose, for example, I’m asked how I know Tom can be trusted to pay back the five dollars you just lent him. I could spend five minutes rehearsing several bits of evidence that would, together, show my claim was reasonable, but that would take time and effort. So, instead I say, “Look, I just know, okay!” To which I might add, “Take my word for it!” And, if you know me to be a pretty good judge of character, you’ll probably be justified in doing so.
Another situation in which it might be appropriate for me to say “I just know” is to flag up that, rather than coming to a belief on the basis of evidence, I can, say, just see, clearly and directly, that such-and-such is the case.
Suppose I’m looking out the window and see our good friend Frank. You’re convinced Frank is away on vacation, so you ask me I’m sure. I might say, “Look, I just know it’s Frank”. What I’m trying to convey is that I can see, very clearly, that it really is Frank. I’m not just hazarding a guess that it’s Frank on the basis of some passing resemblance (the shape of the back of his head, say). Again, knowing me to be a reliable witness, you would probably be justified in taking my word for it.
So saying “I just know” isn’t always an inappropriate thing to say in response to requests for supporting evidence. But then suppose I am asked how I know that God exists, or whether crystals really can cure people. Why can’t it be appropriate and reasonable for me to say, “Look, I just know!” in such situations too?
Maybe, just as I might directly experience Frank walking down the path to my front door, so I might directly experience God. I might just see, as it were, very clearly, that God really does exist. And if it’s reasonable for you to take my word about Frank, then why isn’t reasonable for you take my word about God?
Or, if I have a wealth of evidence that crystals really do have miraculous healing properties, but it would take considerable effort to organize it into a cogent argument – effort I can’t reasonably be expected to make under the circumstances – why isn’t it appropriate for me to say, “Look I just know crystals have these powers”? And if it’s reasonable for you to take my word for it about Tom’s trustworthiness, why not about the healing power of crystals?
We can now begin to see why saying “I just know!” offers those who believe conspiracy theories, wacky religious claims, psychic powers, and so on a potential a “get out of jail free” card. Suppose you find your belief in such things running up against a stiff challenge. Say, “Look, I just know, okay” and you may succeed in putting your critic on the back foot. Make them feel that the onus is now very much on them to demonstrate that you don’t “just know”. Then make quick your escape, head held high, continuing to maintain the superior wisdom that they have failed to show you don’t have.
In this chapter we will be taking a closer look at this sort of appeal to “I just know” to befuddle critics and shut down debate.
When saying “I just know” won’t doWhile “Look, I just know” is sometimes an appropriate thing to say in response to a challenge to your belief, often, it isn’t.
Note, first of all, while there are circumstances in which it might be unreasonable to expect someone to set out the evidence supporting their claim, there are other circumstances in which this excuse won’t wash. If someone is writing a book on a subject, a book in which they have ample time and space available to properly set out their evidence, it obviously won’t do for them to say, “Look, I just know.”
The same is true of important political debates. Politicians are rightly expected to set out their case for raising taxes or invading another country clearly and in detail. Short of their decision being based on, say, top-secret information regarding national security, they have no legitimate excuse for not doing so.
“I just know” is an expression that also crops up at the race track. Suppose Jane puts her money on a horse, and says “I just know it’s going to win.” She says this even though the evidence – the betting odds and so on – suggest it probably won’t win. Even if Jane’s horse does happen to win, we’ll usually be inclined to think that not only did Jane not “just know”, it wasn’t reasonable for her to suppose she did.
Deciding “with your gut”We all go with our gut, intuition, or instinct on occasion. Sometimes it’s unavoidable. Suppose I don’t know whether I should employ someone. The evidence concerning their reliability is somewhat mixed. I’ve received some very positive reports, but also some negative ones. I need to make a snap decision. Under such circumstances, I may just have to go with my gut. It’s that or toss a coin.
It’s been suggested that our gut feelings can be insightful. Police officers often have to make rapid decisions about, say, who is most likely to be armed in a rapidly unfolding and dangerous situation. There’s no time to assess the evidence properly. Officers often just have to go with their instincts. But their instincts are, it’s claimed, surprisingly accurate. They make fairly reliable judgements, despite not engaging in any conscious deliberation or evidence-weighing at all.
So there’s not necessarily anything wrong with going with your gut in certain situations. However, none of this is to say that it’s sensible to go with your gut feeling when you don’t need to, because, say, there’s ample and decisive evidence available. We are also ill-advised to trust the instincts of someone whose particular gut has a poor track record, or to trust our own gut feelings in areas where we know that gut feeling has proved to be unreliable.
Bush’s gutNotoriously, during George W. Bush’s presidency, Bush’s gut became the oracle of the State. Bush was distrustful of book learning and those with established expertise in a given area. When Bush made the decision to invade Iraq, and was subsequently confronted by a skeptical audience, Bush said that ultimately, he just knew in his gut that invading was the right thing to do. As writer Rich Procter noted prior to the invasion:
Now we're preparing to invade a country in the middle of the most volatile "powder-keg" region on earth. We're going to toss out our history of using military force only when provoked. We're going to launch a "pre-emptive" invasion that violates two hundred-plus years of American history and culture. We're on the verge of becoming a fundamentally different kind of nation - an aggressive, "go-it-alone" rogue state - based on Bush's gut… The invasion went ahead. A few months later, Senator Joe Biden told Bush of his growing worries about the aftermath. In response, Bush again appealed to the reliability of his “instincts”, as Ron Suskind here reports:
''I was in the Oval Office a few months after we swept into Baghdad,'' [Biden] began, ''and I was telling the president of my many concerns'' - concerns about growing problems winning the peace, the explosive mix of Shiite and Sunni, the disbanding of the Iraqi Army and problems securing the oil fields. Bush, Biden recalled, just looked at him, unflappably sure that the United States was on the right course and that all was well. '''Mr. President,' I finally said, 'How can you be so sure when you know you don't know the facts?''' Biden said that Bush stood up and put his hand on the senator's shoulder. ''My instincts,'' he said. ''My instincts.'' …The Delaware senator was, in fact, hearing what Bush's top deputies - from cabinet members like Paul O'Neill, Christine Todd Whitman and Colin Powell to generals fighting in Iraq - have been told for years when they requested explanations for many of the president's decisions, policies that often seemed to collide with accepted facts. The president would say that he relied on his ''gut'' or his ''instinct'' to guide the ship of state… How did Bush suppose his gut was able to steer the ship of state? He supposed it was functioning as a sort of God-sensing faculty. Bush believed that by means of his gut he could sense what God wanted of him. But how reasonable was it for Bush, or anyone else, to trust what his gut was telling him?
What is knowledge?Interestingly, a theory of knowledge developed over the last half century or so would seem to have the consequence that it is at least in principle possible (notice I don’t say likely) that some psychics, religious gurus and so on might “just know” things by means of some sort of psychic or divinely-given sense. They might “just know” these things even if they don’t have any evidence to support what they believe. In which case, perhaps Bush might “just know” what God wants of him by means of his gut? Let’s make a short detour of a few pages into contemporary theory of knowledge to look more closely at these ideas.
What is knowledge? Under what circumstances can someone correctly be described as knowing that so-and-so? The classic definition of knowledge comes from the Ancient Greek philosopher Plato, who thought that, in order to know that so-and-so, three conditions must be satisfied:
First, the person in question must believe that so-and-so. In order to know that, say, the battle of Hastings was in 1066, or that there is a pen on my desk, I must believe it.
Second, the belief must be true. I can’t know what isn’t true. If there’s no pen on my desk, then I cannot know that there is (though of course I might still believe it).
Thirdly, Plato thought that, in order to know that so-and-so, I need to be justified in believing that so-and-so. In order to know that the battle of Hastings was in 1066, or that there’s a pen on my desk, I need to be justified in believing these things.
Up until the mid-Twentieth century, this account of knowledge was widely accepted.
The third condition needs a little explanation, perhaps. Justification can take various forms. Perhaps the most obvious way in which you might be justified in believing something is if you have good evidence that what you believe is true. Incidentally, those who sign up to this definition of knowledge don’t normally mean that your justification must guarantee the truth of your belief. They typically allow that you can be justified in believing something even if you are mistaken. For example, surely you are justified in supposing that John is an expert on chemistry after him having shown you round a chemistry laboratory and seen various credentials hanging on his study wall, even though it still remains possible (if unlikely) that John is a con-man and you are the victim of some elaborate, Mission Impossible type fraud.
EvidentialismLet’s now quickly turn to a well-known claim about evidence made by the philosopher W.K. Clifford. Clifford claimed that
it is wrong, always and everywhere, to believe anything on insufficient evidence. People who believe despite not possessing good evidence that their belief is true are being downright irresponsible, thought Clifford. This quotation is often used to condemn those who believe in such things as the Loch Ness monster, angels, fairies and even God. Such beliefs, it is suggested, are not well-supported by the evidence. So it is wrong for people to believe them.
The idea that it is, at the very least, unwise to accept claims for which we possess little or no supporting evidence is certainly widespread. Richard Dawkins, for example, writes:
Next time somebody tells you something that sounds important, think to yourself: ‘Is this the kind of thing that people probably know because of evidence? Or is it the kind of thing that people only believe because of tradition, authority or revelation?’ And next time somebody tells you that something is true, why not say to them: ‘What kind of evidence is there for that?’ And if they can’t give you a good answer, I hope you’ll think very carefully before you believe a word they say. Let’s call the view that we ought not to accept any belief not well-supported by evidence evidentialism. Is evidentialism true?
Probably not. Evidentialism faces some obvious difficulties. Perhaps the most glaring is this. Suppose I believe some claim A because I suppose I have supporting evidence B. But now ought I to believe that evidence B obtains? If evidentialism is true, it seems I ought to believe B obtains only if I posses, in turn, evidence for that – C, say. But then I should believe that C obtains only if there is, in turn, evidence for that, and so on ad infinitum. Evidentialism seems to entail that, before I adopt any belief, I must first acquire evidence to support an infinite number of beliefs – which, as a finite being, I can’t do. In short, Clifford’s injunction that I ought not to believe anything on the basis of insufficient evidence appears to have the disastrous consequence that I ought not to believe anything at all!
A problem for Plato’s theoryLet’s now return for a moment to Plato’s theory that knowledge is justified true belief. It is widely supposed that Plato’s theory runs into a similar problem. The theory says that, in order to know that so-and-so, my belief must be justified. But if my justification is supplied by another belief of mine, then, presumably, I am only justified in believing the first belief if I am justified in believing the second. But then the second belief will require a third belief to justify it, and so on ad infinitum. So, in order to justify even one belief I will have to justify an infinite number. Being a finite being, I cannot justify an infinite series of beliefs. It seems, then, that I cannot justify any belief, and thus cannot know anything at all!
How do we escape from this conclusion? The theory of knowledge known as reliabilism provides one solution.
ReliabilismHere is a simple reliabilist theory of knowledge. In order for person a to know that P,
(i) P must be true
(ii) a must believe that P
(iii) A’s belief that P must be brought about by the fact that P via a reliable mechanism
You will notice that the first two conditions are the same as for Plato’s definition of knowledge. But the third is different, and requires a little explanation.
What’s meant by a “reliable mechanism”? A reliable mechanism is a mechanism that tends to produce true beliefs. My sense of sight is a fairly reliable belief-producing mechanism. It allows my beliefs fairly reliably to track how things are in my environment.
Suppose, for example, someone puts an orange on the table in front of me. Light bounces off the orange into me eyes, which in turn causes certain cells to fire in my retina, which causes a pattern of electrical impulses to pass down my optic nerves into my brain, eventually bringing it about that I believe there’s an orange before me. Remove the orange and that will in turn cause me, by means of the same mechanism, to believe the orange has gone.
The same goes for my other senses – they are fairly reliable belief-producing mechanisms. Blindfold me and put me in a crowded street and my ears, nose will, in response to the sound of car horns and the odour of hot dogs, cause me to believe I am in a crowded street. Move me to a fragrant garden filled with singing birds and those same senses will cause me to believe I am in such a garden. My senses of sight, touch, smell, hearing and taste cause me to hold beliefs that tend accurately to reflect how things actually are around me.
I don’t say our senses are one hundred percent reliable, of course. Sometimes we get things wrong. They are occasionally prone to illusion. But they are fairly reliable.
Let’s now apply our reliabilist definition of knowledge. Suppose someone puts an orange on the table in front of me. I look at the orange, and so come to believe there’s an orange there. Do I know there’s an orange on the table?
According to our reliabilist, I do. The simple reliabilist theory says that if (i) it’s true that there’s an orange there, (ii) I believe there’s an orange there, and (iii) my belief is produced via a reliable mechanism, e.g. sight, by the presence of an orange there, then I know there’s an orange there.
Now here is an interesting twist to this theory – a twist that will prove relevant to our discussion of psychic powers and George Bush’s gut. Notice, that, according to reliablism, in order to know there’s an orange on the table, I need not infer there’s an orange there. I need not arrive at my belief on the basis of good grounds or evidence. No evidence is required. All that’s required is that I hold the belief and that it be produced in the right sort of way – by a reliable mechanism.
Also notice that if, by saying that a belief is “justified”, we mean we have good grounds for believing it, then reliabilism says that we can know without justification. In which case, the regress problem with Plato’s theory that knowledge is justified true belief is also sidestepped by reliabilism.
Reliabilism and psychic powersMany contemporary philosophers accept some form of reliabilism (though they have developed it in various ways). You can now see why reliabilism might also appeal to, say, a psychic who believes she “just knows” things about the dead.
Suppose a psychic (notice that by “psychic” I mean someone who is supposed to have psychic powers, whether or not they actually do) – call her Mary – finds herself believing that her dead Aunt Sarah is currently in the room with her. Also suppose, for the sake of argument, that Mary really does have some sort of reliable psychic sense, that dead Aunt Sarah really is in the room with Mary, and that Mary’s psychic sense is what is causing Mary to believe Aunt Sarah is present. Then, says our reliabilist theory, Mary knows that Aunt Sarah is in the room with her.
Notice that Mary doesn’t infer that Aunt Sarah is present on the basis of evidence. Mary just finds herself stuck with that belief that Aunt Sarah is present, caused as it is by her reliable psychic sense. Yet, says our reliabilist, despite the fact that Mary doesn’t possess any evidence that Aunt Sarah is present, Mary knows Aunt Sarah is there. In fact, were Mary to claim that she “just knows” that Mary is in the room with her right now, she’d be right!
Of course, that they do “just know” such things despite not having any publicly available evidence is a claim psychics make on a daily basis. So, while few psychics will have heard of reliabilism, reliabilism nevertheless opens up at least the possibility that these psychics are actually correct – they do know, despite not possessing any evidence.
“But hang on” you may object. “Even if reliabilism is correct and Mary does know her dead Aunt is in the room with her, that is not something she ought to believe. The fact is, Mary is being downright irresponsible in just accepting at face value this belief that happens to have popped into her head. Clifford is still correct – she shouldn’t believe it. It’s still unwise for her to believe it.”
In her own defence, a Mary might appeal to a further principle. Surely, Mary may insist, If something seems very clearly and obviously to be the case, then, other things being equal, it’s reasonable to believe it’s true. It’s reasonable to take appearance at face value. For example, if it seems clear and obvious to me that there’s on orange on the table before me, then surely it’s reasonable for me to believe there’s an orange there.
This principle does seem intuitively plausible. And it entails that, if it seems just clearly and obviously true to Mary that her dead Aunt is in the room with her, then, other things being equal, it is reasonable for Mary to hold that belief. Whether or not she can provide any publicly available evidence.
Reliabilism and religious experienceLet’s now return to George Bush’s gut. Bush believes he can directly know, by means of his gut, what God wants him to do.
Many people believe that they “just know” directly, rather than on the basis of evidence, that God exists and that, say, the Bible is true. Ask them why they believe, and they may give reasons and justifications of one sort or another. But typically, even if such grounds are provided, not much weight is placed on them. Most Theists will say that they don’t believe on the basis of evidence. Rather, they “just know” God exists. They believe they directly experience God, perhaps in something like the way I just directly experience that orange on the table in front of me. To them, it seems perfectly clear and obvious that God exists.
Reliabilism seems to open up the possibility that some people might, indeed, “just know” that God exists. Suppose God has provided us with a sort of sensus divinitatis – a reliable, God-sensing faculty (in Bush’s case, that would be his gut). On the reliabilist view, it seems that a sensus diviniatis could provide such knowledge.
Moreover, a religious person might add, just as, if it seems clearly and obviously true to me that there’s an orange on the table, then it is reasonable for me to suppose there’s an orange there, so if it seems clearly and obviously true to someone that God exists, then it’s reasonable for them to believe God exists. There’s certainly nothing wrong, or irresponsible, about them taking their experience at face value.
This view about religious experience has been developed by several contemporary Christian philosophers, chief among whom is Alvin Plantinga. Plantinga’s version is detailed, but the gist is essentially this, that something like reliabilism is essentially correct, that God has indeed given everyone of us a God-sensing faculty or sensus divinitatis, and that consequently, some of us can know, directly and without evidence, that God exists. Indeed, that God exists is an entirely reasonable thing for such people to believe if that’s very much how things clearly and obviously seem to them even after careful reflection.
Plantinga adds that, if there is a God, he probably would want us to know of his existence directly by means of such a reliable God-sensing faculty. So, if there is a God, then some of us probably do know by such means that God exists.
You may be wondering: “But if we all have a sensus divinitatis, as Plantinga supposes, why don’t we all enjoy such clear and unambiguous God experiences?” Because, Plantinga explains, in many cases our sensus divinitatis has been damaged by sin:
Were it not for sin and its effects, God’s presence and glory would be as obvious and uncontroversial to us all as the presence of other minds, physical objects and the past. Like any cognitive process, however, the sensus divinitatis can malfunction; as a result of sin, it has been damaged. The reason I don’t have such God experiences, then, is because my sensus divinitatis has been damaged by sin. Obviously, it doesn’t follow that, if I don’t have such experiences, then others aren’t, by means of them, able to know that God exists. To draw that conclusion would be analogous to me, having poked my eyes out and so blinded myself to the orange on the table in front of me, defiantly claiming, “I don’t see any orange on the table, so – even if there is– you certainly don’t know there’s any orange there!”
Assessing psychic and religious claims to “just know”We have seen how the reliabilist theory of knowledge seems to open up the possibility that some people might “just know” that their dead relative is in the room with them, or “just know” that God exists. We have also seen that evidentialism has been challenged, and that, according to Plantinga and others, it can be entirely reasonable for people to take their religious experiences at face value. If it seems just clearly and obviously true to them that God exists, then it can entirely reasonable for them to believe God exists, whether or not they possess any evidence. Psychics might say much the same thing about their psychic experiences. Let’s now begin to assess these various claims.
Let me say at the outset that I find reliabilism plausible. I suspect that some version of reliabilism may well be correct. Let me also be clear that I do not rule out in principle the possibility that some people might be equipped with reliable psychic powers, or a sensus divinitatis, or whatever.
I also agree that evidentialism is probably false, and that, generally speaking, it is indeed reasonable for us to take appearances at face value. If it seems just clearly and obviously the case that there’s an orange on the table in front of me, well then, other things being equal, it’s reasonable for me to believe there’s an orange on the table in front of me.
However, I remain entirely unconvinced that anyone who claims to “just know” that the dead walk among us, or that God exists, knows any such thing. Not only do I think the rest of us have good grounds for doubting their experience, I don’t believe it’s reasonable for them to take their own experience at face value either. I’ll explain why by means of what I call the case of the mad, fruit-fixated brain scientist.
The case of the mad, fruit-fixated brain scientistSuppose Jane is shown what appears, quite clearly and obviously, to be an orange on the table in front of her. Surely then, it is, other things being equal, reasonable for Jane to believe there’s an orange there.
But now suppose the orange is presented to Jane in a rather unusual situation. Jane is one of several visitors to the laboratory of a mad brain scientist with a weird fruit fixation. She, like the other visitors, is wearing an electronic helmet that can influence what happens in her brain. From his central computer terminal, the mad brain scientist can, by means of these helmets, control what people are experiencing. He can create vivid and convincing hallucinations.
The scientist demonstrates by causing one of the visitors to hallucinate an apple. There’s much hilarity as the victim tries to grab for the fruit that’s not there. The visitors are then invited to wander round the lab where, the scientist tells them, they may experience several other virtual fruit. Jane then comes across what appears to be an orange on a table. Now, as a matter of fact, it is a real orange – one that fell out of someone’s packed lunch bag. Jane’s faculty of sight is functioning normally and reliably. This is no hallucination.
Now ask yourself two questions: (i) does Jane know there’s an orange on the table? And (ii) is it reasonable for Jane to suppose there’s an orange on the table?
Intuitively, it seems Jane doesn’t know there’s an orange present. After all, for all Jane knows, it could be one of the many hallucinatory fruit she knows about. But what would a reliabilist say? Well, sight is generally a reliable belief producing mechanism, and sight is what’s producing her belief. So some reliabilists may say that, yes, Jane does know. On the other hand, very many reliabilists say that, while in a standard environment, sight is reliable, it isn’t reliable in other kinds of environment, e.g. the kind of environment in which we will often as not be deceived by visual hallucinations. But then it follows that, because she is in just such an environment, Jane doesn’t know.
Now let’s turn to question (ii), which is the pivotal question: is it reasonable for Jane to believe there’s an orange before her?
Surely not. Given Jane knows that she is in an environment (the mad brain scientist’s laboratory) in which people regularly have compelling fruit hallucinations (indistinguishable from real fruit experiences), Jane should remain rather skeptical about her own fruit experience. For all she can tell, she’s probably having a mad-scientist-induced fruit hallucination.
I draw two morals for religious experience:
First of all, even if reliabilism is true, and even if some of us do have God-experiences produced by a sensus divinitatis, it remains debatable whether such people know that God exists. If human beings are highly prone to delusional religious experiences that they nevertheless find entirely convincing, then, even if, as a matter of fact, I happen to be having a wholly accurate religious experience revealing that, say, the Judeo-Christian God exists, it’s by no means clear I can be said to know the Judeo-Christian God exists, any more than Jane, coming upon a real orange in the brain scientist’s lab, can be said to know that there’s an orange on the table in front of her.
Second, and more importantly, even if it’s true, because of my religious experience, that I do know that the Judeo-Christian God exists, surely it still isn’t reasonable for me to take my experience at face value. For I find myself in a situation much like Jane finds herself in the brain scientist’s lab. Even though it looks to Jane clearly and obviously to be true that there’s an orange on the table in front of her, Jane should, surely, remain pretty skeptical about whether there’s actually an orange there, given that, for all she knows, she might very easily be having one of the many delusional fruit experiences currently being generated in the lab. Jane would be foolish to take appearance at face value. Similarly, if I have good evidence that many religious experiences are delusional – even the most compelling examples – then surely I should be equally skeptical about my own religious experiences, no matter how compelling those experiences might be. I would be foolish for me to take my experiences at face value.
A similar morals might be drawn about psychic experiences. If most – including even the most compelling examples – are delusional, then it’s debatable whether the psychic can be said to know. However, even if the psychic can be said to know, if they’re aware that many such experiences are delusional, then it surely isn’t reasonable for such a person to take their experience at face value. They would be foolish to do so.
The dubious nature of religious experienceThe above argument presupposes that there is good evidence that most psychic and religious experiences are delusional – even the most compelling examples. Which of course there is. Let’s focus on religious experience. We know that:
(i) Religious experiences tend to be culturally specific. Christians experience the guiding hand of Jesus, while Muslims experience Allah. Just like experiences of alien abduction (reports of alien abduction pretty much stop at certain national borders), the character of religious experiences often changes at national borders. In Catholic countries, the Virgin Mary is often seen, but not over the border in a predominantly Muslim country. This strongly suggests that to a significant degree religious experiences are shaped by our cultural expectations – by the power of suggestion (see Piling Up The Anecdotes). And once we know that a large part of what is experienced is a result of the power of suggestion, we immediately have grounds for being somewhat suspicious about what remains.
(ii) Religious experiences often contradict each other. George W. Bush’s gut told him God wanted war with Iraq. However, the religious antenna of other believers – including other Christians – tell them God wanted peace. Some religious people claim to know by virtue of a revelatory experience that Christ is divine and was resurrected. Muslims, relying instead on the religious revelations of the prophet Mohammad, deny this. Religious experience reveals that some Gods are cruel and vengeful, some even requiring the blood of children (The Mayan and Aztec gods, for example), while others are loving and kind. The religious experiences of some Buddhists reveal there’s no personal God, whereas those of many Christians Jews and Muslims reveal that there is but one personal God. Other religions have a pantheon of Gods. Take a step back and look at the sweep of human history, and you find an extraordinary range of such experiences. Religious revelation has produced a vast hodge-podge of contradictory claims, many of which must, therefore, be false. Even those who believe they have had things directly revealed to them by God must acknowledge that a great many equally-convinced people are deluded about what has supposedly been revealed to them.
There are similar reasons for supposing the bulk of psychic experiences are also delusional. What is revealed to psychics is often wrong, often contradicted by what other psychics claim, and so on.
For these reasons, then, it’s not reasonable for me to take my psychic or religious experience at face value – not even if it’s very vivid and convincing. It might be genuinely revelatory. But, under the circumstances, it would be rather foolish of me to assume that it is. Those who, like George W. Bush, place a simple trusting faith in their gut, or wherever else they think their sensus divinitatis is located, are being irresponsible and foolish.
Notice that it would be particularly foolhardy for, say, someone who believes in an all-powerful, all-knowing and all-good God, but who is confronted with the evidential problem of evil, to sweep the problem to one side, saying, “But look, I just know in my heart [or gut, or wherever] that my God exists!” While it might remain a theoretical possibility that they do “just know”, it’s certainly not reasonable for them to maintain this – not if they have been presented with both (i) good evidence that many such experiences are delusional, and (ii) powerful empirical evidence that what they believe is false. To insist one “just knows” under these circumstances is very unreasonable indeed.
The common core of religious experience – “ineffable transcendence”?Some will say that it is unfair to lump all religious experiences together. There is a certain kind of experience - the sort enjoyed by the mystics of many different religions down through the centuries - that is essentially the same. What is this experiential common denominator? According to Karen Armstrong, it is an experience of “indescribable transcendence”. As we saw in Moving The Goalposts, Armstrong’s view is that “God” is merely a symbol for this transcendence. Once we strip away the cultural artifacts peculiar to the different mainstream religions, we find they all have this common, experiential core.
According to Armstrong, such experiences of indescribable transcendence typically don’t just happen. Usually, they emerge only after subjects have committed themselves over an extended period of time to a particular sort of lifestyle – a religious lifestyle. Religion, on Armstrong’s way of thinking, is not a body of doctrine (how could it be, if that towards which religion is orientated is ineffable?) but an activity: the kind of activity that produces experiences of this sort. Religion, says Armstrong, is
a practical discipline, and its insights are not derived from abstract speculation but from spiritual exercises and a dedicated lifestyle. By engaging in certain religious practices and forms of life, maintains Armstrong, people can come to live “on a higher, divine or godlike plane and thus wake up their true selves.”
Some noteworthy features of religious practiceSuppose, then, that having immersed themselves in such a lifestyle, someone claims to “just know” that there is indeed such an ineffable transcendence? Is it reasonable for us, or for them, to suppose they’ve achieved awareness of Armstrong’s “sacred reality”?
I don’t believe so. As Armstrong acknowledges, religious practice takes many forms involving a variety of activities. An interesting feature of many of these activities is that we know they can induce interesting – sometimes rather beneficial – psychological states, even outside of a religious setting. Let’s look at some examples:
Meditation and prayer. Consider meditation. It has proven effects on both our psychology and physiology. It can reduce stress, lower blood pressure and induce feelings of calm and contentment. Even atheists meditate to gain these benefits. Prayer can be a form of meditation, of course. Sometimes prayer and other devotional activities are accompanied by repetitive swaying or rocking motions known to induce a sense of well-being – the so-called “jogger’s high” (though this is not, as is widely believed, a result of releasing endorphins).
Isolation. Isolation can have a powerful psychological effect on people. It can render them more easily psychologically manipulated (which is why isolation is a favourite tool of interrogators) and can produce hallucinations and other altered states of consciousness. Many religions encourage periods of isolation for spiritual purposes – several days in the wilderness say.
Fasting. Fasting, too, is known to produce some peculiar psychological states, including hallucinations, even outside of a religious setting.
Collective singing/chanting. Coming together in a large group to chant or sing can also be a very intoxicating experience, as anyone who has sat on a football terrace can testify.
Architecture. If you have ever entered a large cave by torchlight, you will know that it too can induce a powerful emotional experience. The darkness, echoing sounds, and glimpses of magnificent structures making one fearful and yet excited all at the same time – leading us to start talking in whispers. The echoing grandeur of many places of worship has a similar psychological effect.
Giving. Helping others in face-to-face situation can be an immensely powerful psychological experience - often a deeply gratifying and positive experience, whether or not you happen to do it in a religious setting.
Ritual. Engaging in ritualistic activity often has a calming and beneficial effect, whether or not performed within a religious setting. For example, sportsmen and women often engage in rituals before competing (and can become very disturbed if for some reason the ritual cannot be performed because e.g. their lucky shirt has been lost).
Religious practice typically involves at least some of, and usually, many of, these activities. Activities we know can have a powerful psychological effect even outside of any religious setting. If people collectively engage in such activities with intensity of purpose over a long period of time, this might very well have a marked psychological effect. It might well produce some interesting, and quite possibly beneficial, psychological states.
If we then mix into this heady and intoxicating brew the suggestion that what people are experiencing or becoming psychological attuned to as a result of long term engagement in such regime is some sort of ineffable transcendence, then, given the power of suggestion (see Piling Up The Anecdotes, p xxx), many will probably become quite convinced that this is what’s going on.
The experiences and insights that, as a result of the regime, then coalesce under the label “God” will no doubt be complex and difficult to articulate. There probably is a sense in which someone who has never been through such a regime will not fully appreciate what the experience is actually like for the subject, “from the inside” as it were. Those who have had such an experience will no doubt struggle to communicate its character in much same way that someone who has been through, say, a war or childbirth may struggle. They may well have to resort to poetry or music or other art forms in order to convey its unique intensity.
Armstrong says,
[i]t is clear that the meditation, yoga and rituals that work aesthetically on a congregation have, when practised assiduously over a lifetime, a marked effect on the personality – an effect that is another form of natural theology. There is no ‘born again’ conversion, but a slow, incremental and imperceptible transformation… The effect of these practices cannot give us concrete information about God; it is certainly not a scientific ‘proof’. But something indefinable happens to people who involve themselves in these disciplines with commitment and talent. The ‘something’ remains opaque, however, to those who do not undergo these disciplines… While it may indeed be difficult for those of us that have not been through such a process to appreciate exactly what it’s like to be in the kind of psychological state it can produce, surely we have pretty good grounds for doubting that what is experienced is some sort of transcendent reality. Given what we know about human psychology, it’s likely that people put through such an intense regime over an extended period of time will think they have become attuned to such a reality anyway, whether or not any such reality exists, and whether or not they have obtained any sort of genuine insight into it.
I don’t wish to deny there is value in engaging in meditation, yoga, and so on. It may well be that those who engage in such practices gain some valuable insights into themselves and the human condition as a result. Certainly, there may be some positive psychological effects, such as a lasting sense of peace and contentment, from determinedly engaging in such activities over a long period of time, effects that will undoubtedly by magnified by the accompanying thought that what they are becoming attuned to is “God”.
But the claim that they have thereby become attuned to some sort of “sacred reality” is dubious to say the least. Surely, given our understanding of human psychology, by far the best explanation of what people experience after having engaged in religious practice with dedication over long periods of time is not that they have become attuned to some sort of ineffable transcendence, but that they have succeeded in altering their own psychology by fairly well-understood mechanisms common to both the religious and non-religious spheres, and that they have then mistakenly interpreted this alteration as their becoming attuned to such a reality.
ConclusionAs we have seen, “I just know” isn’t always unreasonable thing to say. But sometimes it is. Indeed, sometimes it’s a foolish thing to say.
Consider these two examples:
… sometimes I see images and I just know something terrible has happened to them. Psychic Margaret Solis quoted in “The Scots psychic helping Hollywood stars - and hunting down murder victims”, Daily Record, 14th September, 2010
How do I know when God is talking to me? I just know. Internet comment.
Suppose these individuals claiming to “just know” can’t provide any sort of publicly available evidence or rational argument to back up what they claim to “just know”. We have seen that, if reliabilism is true, then the fact that they don’t have any such evidence or argument does not rule out the possibility that they “just know”. However, given what we, and presumably they, know about the unreliability of such psychic and religious experiences generally, surely it’s not reasonable for either us, or them, to take such seemingly revelatory experiences at face value. It’s not reasonable for them to insist they “just know”.
