Start at the Beginning

This post will have two kinds of readers:

1) The few who have read the posts on this blog from the beginning, in chronological order, and who are now reading this one simply because it is the only one you have not read yet.

2) The vast majority who did not do the above.

For the first category, I don’t have any particular suggestion at the moment. Well done. That is the right way of reading this blog.

For the second category, you would do much better to stop right here in the middle of this post (without even finishing it), go back to the beginning, and read every post in chronological order.

….

So you are now in the first category? No? Since obviously you did not take my advice, let me explain both why you should, and why you will not.

It is possible to understand something through arguments, even if manipulating symbols may be an even more common result. And since conclusions follow from premises, you can only do this by thinking about the premises first, and the conclusions second. Since my own interest is in understanding things, I intentionally organize the blog in this way. Of course, since the concrete historical process of an individual coming to understand some particular thing is messier and more complicated than a single argument or even than multiple arguments, the order isn’t an exact representation of my own history or someone else’s potential history. But it is certainly closer to that than any other order of reading would be.

You will object that you do not have the time to read 300 blog posts. Fine. But then why do you have time to read this one? Even if you are definitely committed to reading a small number of posts, you would do better to read a small number from the beginning. If you are committed to reading not more than one post a week, you would do better to read the 300 posts over the next six years, rather than reading the posts that are current.

You might think of other similar objections, but they will all fail in similar ways. If you are actually interested in understanding something from your reading, chronological order is the right order.

Of course, other blog authors might well argue in similar ways, but the number of people who actually do this, on any blog, is tiny. Instead, people read a few recent posts, and perhaps a few others if there are a chain of links that lead them there. But they do not, in the vast majority of cases, read from the beginning, whether to read all or only a part.

So let me explain why you will not take this advice, despite the fact that it is irrefutably correct. In The Elephant in the Brain, Robin Hanson and Kevin Simler remark in a chapter on conversation:

This view of talking—as a way of showing off one’s “backpack”—explains the puzzles we encountered earlier, the ones that the reciprocal-exchange theory had trouble with. For example, it explains why we see people jockeying to speak rather than sitting back and “selfishly” listening—because the spoils of conversation don’t lie primarily in the information being exchanged, but rather in the subtextual value of finding good allies and advertising oneself as an ally. And in order to get credit in this game, you have to speak up; you have to show off your “tools.”

…

But why do speakers need to be relevant in conversation? If speakers deliver high-quality information, why should listeners care whether the information is related to the current topic? A plausible answer is that it’s simply too easy to rattle off memorized trivia. You can recite random facts from the encyclopedia until you’re blue in the face, but that does little to advertise your generic facility with information.

Similarly, when you meet someone for the first time, you’re more eager to sniff each other out for this generic skill, rather than to exchange the most important information each of you has gathered to this point in your lives. In other words, listeners generally prefer speakers who can impress them wherever a conversation happens to lead, rather than speakers who steer conversations to specific topics where they already know what to say.

Hanson and Simler are trying to explain various characteristics of conversation, such as the fact that people are typically more interested in speaking than in listening, as well as the requirement that conversational participants “stick to the topic.”

Later, they associate this with people’s interest in news:

Why have humans long been so obsessed with news? When asked to justify our strong interest, we often point to the virtues of staying apprised of the important issues of the day. During a 1945 newspaper strike in New York, for example, when the sociologist Bernard Berelson asked his fellow citizens, “Is it very important that people read the newspaper?” almost everyone answered with a “strong ‘yes,’ ” and most people cited the “ ‘serious’ world of public affairs.”

…

Now, it did make some sense for our ancestors to track news as a way to get practical information, such as we do today for movies, stocks, and the weather. After all, they couldn’t just go easily search for such things on Google like we can. But notice that our access to Google hasn’t made much of a dent in our hunger for news; if anything we read more news now that we have social media feeds, even though we can find a practical use for only a tiny fraction of the news we consume.

There are other clues that we aren’t mainly using the news to be good citizens (despite our high-minded rhetoric). For example, voters tend to show little interest in the kinds of information most useful for voting, including details about specific policies, the arguments for and against them, and the positions each politician has taken on each policy. Instead, voters seem to treat elections more like horse races, rooting for or against different candidates rather than spending much effort to figure out who should win. (See Chapter 16 for a more detailed discussion on politics.)

…

These patterns in behavior may be puzzling when we think of news as a source of useful information. But they make sense if we treat news as a larger “conversation” that extends our small-scale conversation habits. Just as one must talk on the current topic in face-to-face conversation, our larger news conversation also maintains a few “hot” topics—a focus so strong and so narrow that policy wonks say that there’s little point in releasing policy reports on topics not in the news in the last two weeks. (This is the criterion of relevance we saw earlier.)

The argument here suggests that blog readers will tend to prefer reading current posts to old ones because this is to remain more “relevant,” and that such relevance is necessary in order to impress other conversational participants. This, I suggest, is why you will not take my advice, despite its rightness. If you think this is an insulting explanation, just bear in mind that blog authors are even more insulted by Hanson’s and Simler’s explanations, since the reader at least is listening.

Ezekiel Bulver on Descartes

C.S. Lewis writes:

In other words, you must show that a man is wrong before you start explaining why he is wrong. The modern method is to assume without discussion that he is wrong and then distract his attention from this (the only real issue) by busily explaining how he became to be so silly. In the course of the last fifteen years I have found this vice so common that I have had to invent a name for it. I call it “Bulverism.” Some day I am going the write the biography of its imaginary inventor, Ezekiel Bulver, whose destiny was determined at the age of five when he heard his mother say to his father – who had been maintaining that two sides of a triangle were together greater than the third – “Oh, you say that because you are a man.” “At that moment,” E. Bulver assures us, “there flashed across my opening mind the great truth that refutation is no necessary part of argument. Assume your opponent is wrong, and then explain his error, and the world will be at your feet. Attempt to prove that he is wrong or (worse still) try to find out whether he is wrong or right, and the national dynamism of our age will thrust you to the wall.” That is how Bulver became one of the makers of the Twentieth Century.

In the post linked above, we mainly discussed “explaining how he came to be so silly” in terms of motivations. But Ezekiel Bulver has a still more insidious way of explaining people’s mistakes. Here is his explanation of the mistakes of Descartes (fictional, of course, like the rest of Bulver’s life):

Descartes was obsessed with proving the immortality of the soul and the existence of God. This is clear enough from his own statements regarding the purpose of the Meditations. This is why he makes, “I think, therefore I am,” the fundamental principle of his entire system. And he derives everything from this single principle.

Someone who derives everything from such a thought, of course, is almost sure to be wrong about everything, since not much can actually follow from that thought, and in any case it is fundamentally misguided to derive conclusions about the world from our ideas about knowledge, rather than deriving conclusions about knowledge from our knowledge of the world.

While Bulver includes here a reference to a motive, namely the desire to prove the immortality of the soul and the existence of God, his main argument is that Descartes is mistaken due to the flawed order of his argument.

As I suggested above, this is even more insidious than the imputation of motives. As I pointed out in the original discussion of Bulverism, having a motive for a belief does not exclude the possibility of having an argument, nor does it exclude the possibility the argument is a strong one, nor does it exclude the possibility that one’s belief is true. But in the case under consideration, Bulver is not giving a cause rather than a reason; he is saying that Descartes has reasons, but that they are necessarily flawed ones, because they do not respect the natural order of knowing. The basic principle is the same: assume that a man is wrong, and then explain how he got to be wrong. The process appears more reasonable insofar as reasons are imputed to the person, but they are more exclusive of the person’s real reasons, while motives do not exclude any reasons.

As we have seen, Bulver is mistaken about Descartes. Descartes does not actually suppose that he derives his knowledge of the world from his knowledge of thought, even if he organizes his book that way.

 

Image and Reality

A number of the issues we have discussed can be considered in parallel. There are significant differences between them, but we have given three situations where there was one understanding, at least in the early Church and sometimes later, and after time there was a different understanding. The three issues are the genre of Genesis, the time of the end of the world, and the number of the saved.

The cases differ significantly. In regard to Genesis, it is fairly certain that it was interpreted mainly literally throughout most of Christian history, but there were also some exceptions, at least for some passages. There are literary reasons for supposing that it should not be interpreted in this way, and I presented some of them in the linked post, but in practice the change in understanding came about because the facts were inconsistent with supposing that it was a literal historical account. Fr. Harrison objects exactly for this reason: according to him, it is completely unreasonable to change your understanding of the text to conform to the facts. Nor is the change universal; many ordinary Christians and Catholics would still understand the text in a historically literal way. But this is surely not the current understanding of the Magisterium, nor is it objectively reasonable.

In regard to the time of the end, it is likely that the understanding that it would be soon was nearly universal in the early Church, but this cannot be demonstrated with certainty, since this understanding had to change very quickly in order to remain in conformity with experience. The changed understanding itself would thus be universal, although some take this farther than others; thus James Chastek in the linked post argued that the Second Coming is something that happens after human history has already been concluded, but not everyone would say this.

In regard to the number of the saved, the issue was surely much less important. Christ himself at least on one occasion seems to have refused to answer the question: one should not be concerned about how many are saved, but to strive for salvation. And the idea that most people are lost was surely not universal. Origen for example argued that all will be saved. And likewise, I have given only the example of Pope Benedict XVI currently arguing that most people are saved, while it is not clear how common this opinion is. Nonetheless, I have included this because of significant similarities. The Catholic doctrine of the Last Judgement implies that there is a deep truth behind the human tendency to divide people into good people and bad people. According to the doctrine, people will in fact be divided in this way, and the division will last for all eternity. But the human tendency is a bit different. As I suggested in the linked post, people frequently tend to make such a division on the basis of religion and politics and similar matters. Democrats might say that Republicans are heartless evil people; Christians might say that atheists are sinful and immoral people who have rebelled against God. Such a division is sometimes even taken so far that it is incorporated into a person’s idea of religious doctrine: thus for example some people hold a rigid understanding of the idea that there is no salvation outside the Church, and some Muslims say that all non-Muslims go to hell.

In this sense, the natural human tendency is surely deeply flawed. Just because people do not agree with you, or just because they do not belong to your communities, does not mean that they are evil people. If anything, it is obvious that most people are not deeply evil. On the one hand, this provides ammunition for people who would engage in Bulverism against the Christian doctrine; they can say that the doctrine may simply be a result of this flawed tendency. On the other hand, it provides an argument in favor of Pope Benedict XVI’s position, and in fact it is more or less the argument that he makes. This is why I have included it: Christ said certain things, which understood in a fairly simple way seem to imply certain things about the time of the end and the number of the saved. Likewise, Genesis says things which similarly can be taken to imply certain facts about the history of the world. Over time, everyone realized that what seemed implied about the time of the end, simply could not be the case. Many people realized that what seemed implied about the history of the world could not be the case, and at least some people realized that what seemed implied about the number of the saved is unlikely to be the case.

These surely differ in their doctrinal weight. The number of the saved is probably unimportant in a doctrinal sense, even if it might be important to us personally. The other two seem somewhat more important, but it not difficult to argue that such changes do not involve the substance of any doctrine. As I have said previously, one would not describe a contradiction as such as a development. So “the world will not end soon” cannot be a development of “the world will end soon,” but it would not be unreasonable to say that Christians went from one to the other through an improved understanding of the meaning and history of the Church, even if it was one that was forced upon them by the facts. In this sense, it is not unreasonable to understand all of these things in conformity with Newman’s idea of development of doctrine.

But something seems missing here. All of the facts may be consistent with Newman’s idea, but that does not mean that they are not consistent with anything else. And if anything, they seem more suggestive of the hypothesis that Newman rejects, that “Christianity has ever changed from the first and ever accommodates itself to the circumstances of times and seasons,” and which seems to imply that Christianity is not supernatural. To a non-Christian, these facts look like the early Christians were just ignorant, and their ignorance was overcome through the normal progress in the knowledge of truth. And to the extent that they received their religion from Christ, and even to some extent apparently these specific ideas, it looks like Christ was ignorant as well.

Pope Benedict XVI discusses a similar situation in his homilies on Genesis, published as the book In the Beginning:

These words, with which Holy Scripture begins, always have the effect on me of the solemn tolling of a great old bell, which stirs the heart from afar with its beauty and dignity and gives it an inkling of the mystery of eternity. For many of us, moreover, these words recall the memory of our first encounter with Gods holy book, the Bible, which was opened for us at this spot. It at once brought us out of our small child’s world, captivated us with its poetry, and gave us a feeling for the immeasurability of creation and its Creator.

Yet these words give rise to a certain conflict. They are beautiful and familiar, but are they also true? Everything seems to speak against it, for science has long since disposed of the concepts that we have just now heard of – the idea of a world that is completely comprehensible in terms of space and time, and the idea that creation was built up piece by piece over the course of seven days. Instead of this we now face measurements that transcend all comprehension. Today we hear of the Big Bang, which happened billions of years ago and with which the universe began its expansion – an expansion that continues to occur without interruption. And it was not in neat succession that the stars were hung and the green of the fields created; it was rather in complex ways and over vast periods of time that the earth and the universe were constructed as we now know them.

Do these words, then, count for anything? In fact a theologian said not long ago that creation has become an unreal concept. If one is to be intellectually honest one ought to speak no longer of creation but rather of mutation and selection. Are these words true? Or have they perhaps, along with the entire Word of God and the whole biblical tradition, come out of the reveries of the infant age of human history, for which we occasionally experience homesickness but to which we can nevertheless not return, inasmuch as we cannot live on nostalgia? Is there an answer to this that we can claim for ourselves in this day and age?

He is discussing the specific issue of the truth of Genesis, and thus his response is tailored to this:

One answer was already worked out some time ago, as the scientific view of the world was gradually crystallizing; many of you probably came across it in your religious instruction. It says that the Bible is not a natural science textbook, nor does it intend to be such. It is a religious book, and consequently one cannot obtain information about the natural sciences from it. One cannot get from it a scientific explanation of how the world arose; one can only glean religious experience from it. Anything else is an image and a way of describing things whose aim is to make profound realities graspable to human beings. One must distinguish between the form of portrayal and the content that is portrayed. The form would have been chosen from what was understandable at the time – from the images which surrounded the people who lived then, which they used in speaking and thinking, and thanks to which they were able to understand the greater realities. And only the reality that shines through these images would be what was intended and what was truly enduring. Thus Scripture would not wish to inform us about how the different species of plant life gradually appeared or how the sun and the moon and the stars were established. Its purpose ultimately would be to say one thing: God created the world. The world is not, as people used to think then, a chaos of mutually opposed forces; nor is it the dwelling of demonic powers from which human beings must protect themselves. The sun and the moon are not deities that rule over them, and the sky that stretches over their heads is not full of mysterious and adversary divinities. Rather, all of this comes from one power, from God’s eternal Reason, which became – in the Word – the power of creation. All of this comes from the same Word of God that we meet in the act of faith. Thus, insofar as human beings realized that the world came from the Word, they ceased to care about the gods and demons. In addition, the world was freed so that reason might lift itself up to God and so that human beings might approach this God fearlessly. In this Word they experienced the true enlightenment that does away with the gods and the mysterious powers and that reveals to them that there is only one power everywhere and that we are in his hands. This is the living God, and this same power (which created the earth and the stars and which bears the whole universe) is the very one whom we meet in the Word of Holy Scripture. In this Word we come into contact with the real primordial force of the world and with the power that is above all powers.

After this description of a response to the problem, he says that there is still a problem:

I believe that this view is correct, but it is not enough. For when we are told that we have to distinguish between the images themselves and what those images mean, then we can ask in turn: Why wasn’t that said earlier? Evidently it must have been taught differently at one time or else Galileo would never have been put on trial. And so the suspicion grows that ultimately perhaps this way of viewing things is only a trick of the church and of theologians who have run out of solutions but do not want to admit it, and now they are looking for something to hide behind. And on the whole the impression is given that the history of Christianity in the last four hundred years has been a constant rearguard action as the assertions of the faith and of theology have been dismantled piece by piece. People have, it is true, always found tricks as a way of getting out of difficulties. But there is an almost ineluctable fear that we will gradually end up in emptiness and that the time will come when there will be nothing left to defend and hide behind, that the whole landscape of Scripture and of the faith will be overrun by a kind of “reason” that will no longer be able to take any of this seriously.

Along with this there is another disquieting consideration. For one can ask: If theologians or even the church can shift the boundaries here between image and intention, between what lies buried in the past and what is of enduring value, why can they not do so elsewhere – as, for instance, with respect to Jesus’ miracles? And if there, why not also with respect to what is absolutely central – the cross and the resurrection of the Lord? This would be an operation whose aim would be, supposedly, to defend the faith, inasmuch as it would say: Behind what is there, which we can no longer defend, there is something more real. Such an operation often ends up by putting the faith itself in doubt, by raising the question of the honesty of those who are interpreting it and of whether anything at all there is enduring. As far as theological views of this sort are concerned, finally, quite a number of people have the abiding impression that the church’s faith is like a jellyfish: no one can get a grip on it and it has no firm center. It is on the many halfhearted interpretations of the biblical Word that can be found everywhere that a sickly Christianity takes its stand – a Christianity that is no longer true to itself and that consequently cannot radiate encouragement and enthusiasm. It gives, instead, the impression of being an organization that keeps on talking although it has nothing else to say, because twisted words are not convincing and are only concerned to hide their emptiness.

This concern is much like that of Ross Douthat in his comments regarding communion for divorced and remarried couples.

I will give Ratzinger’s response to these issues, and offer some comments on it, in the next post, or possibly later.

C.S. Lewis on Bulverism

C.S. Lewis begins his essay on Bulverism:

It is a disastrous discovery, as Emerson says somewhere, that we exist. I mean, it is disastrous when instead of merely attending to a rose we are forced to think of ourselves looking at the rose, with a certain type of mind and a certain type of eyes. It is disastrous because, if you are not very careful, the color of the rose gets attributed to our optic nerves and its scent to our noses, and in the end there is no rose left. The professional philosophers have been bothered about this universal black-out for over two hundred years, and the world has not much listened to them. But the same disaster is now occurring on a level we can all understand.

We have recently “discovered that we exist” in two new senses. The Freudians have discovered that we exist as bundles of complexes. The Marxians have discovered that we exist as members of some economic class. In the old days it was supposed that if a thing seemed obviously true to a hundred men, then it was probably true in fact. Nowadays the Freudian will tell you to go and analyze the hundred: you will find that they all think Elizabeth [I] a great queen because they all have a mother-complex. Their thoughts are psychologically tainted at the source. And the Marxist will tell you to go and examine the economic interests of the hundred; you will find that they all think freedom a good thing because they are all members of the bourgeoisie whose prosperity is increased by a policy of laissez-faire. Their thoughts are “ideologically tainted” at the source.

The person probably most known for making the first point, about sensation, is John Locke. He says in his Essay Concerning Human Understanding:

9. Primary qualities of bodies. Qualities thus considered in bodies are,

First, such as are utterly inseparable from the body, in what state soever it be; and such as in all the alterations and changes it suffers, all the force can be used upon it, it constantly keeps; and such as sense constantly finds in every particle of matter which has bulk enough to be perceived; and the mind finds inseparable from every particle of matter, though less than to make itself singly be perceived by our senses: v.g. Take a grain of wheat, divide it into two parts; each part has still solidity, extension, figure, and mobility: divide it again, and it retains still the same qualities; and so divide it on, till the parts become insensible; they must retain still each of them all those qualities. For division (which is all that a mill, or pestle, or any other body, does upon another, in reducing it to insensible parts) can never take away either solidity, extension, figure, or mobility from any body, but only makes two or more distinct separate masses of matter, of that which was but one before; all which distinct masses, reckoned as so many distinct bodies, after division, make a certain number. These I call original or primary qualities of body, which I think we may observe to produce simple ideas in us, viz. solidity, extension, figure, motion or rest, and number.

10. Secondary qualities of bodies. Secondly, such qualities which in truth are nothing in the objects themselves but powers to produce various sensations in us by their primary qualities, i.e. by the bulk, figure, texture, and motion of their insensible parts, as colours, sounds, tastes, &c. These I call secondary qualities. To these might be added a third sort, which are allowed to be barely powers; though they are as much real qualities in the subject as those which I, to comply with the common way of speaking, call qualities, but for distinction, secondary qualities. For the power in fire to produce a new colour, or consistency, in wax or clay — by its primary qualities, is as much a quality in fire, as the power it has to produce in me a new idea or sensation of warmth or burning, which I felt not before — by the same primary qualities, viz. the bulk, texture, and motion of its insensible parts.

It is possible that this is actually mostly true, and mostly consistent with the philosophy of Aristotle, even though Locke would likely wish that the latter were not the case. Aristotle says in On the Soul:

If it is true that the movement, both the acting and the being acted upon, is to be found in that which is acted upon, both the sound and the hearing so far as it is actual must be found in that which has the faculty of hearing; for it is in the passive factor that the actuality of the active or motive factor is realized; that is why that which causes movement may be at rest. Now the actuality of that which can sound is just sound or sounding, and the actuality of that which can hear is hearing or hearkening; ‘sound’ and ‘hearing’ are both ambiguous. The same account applies to the other senses and their objects. For as the-acting-and-being-acted-upon is to be found in the passive, not in the active factor, so also the actuality of the sensible object and that of the sensitive subject are both realized in the latter. But while in some cases each aspect of the total actuality has a distinct name, e.g. sounding and hearkening, in some one or other is nameless, e.g. the actuality of sight is called seeing, but the actuality of colour has no name: the actuality of the faculty of taste is called tasting, but the actuality of flavour has no name. Since the actualities of the sensible object and of the sensitive faculty are one actuality in spite of the difference between their modes of being, actual hearing and actual sounding appear and disappear from existence at one and the same moment, and so actual savour and actual tasting, &c., while as potentialities one of them may exist without the other. The earlier students of nature were mistaken in their view that without sight there was no white or black, without taste no savour. This statement of theirs is partly true, partly false: ‘sense’ and ‘the sensible object’ are ambiguous terms, i.e. may denote either potentialities or actualities: the statement is true of the latter, false of the former. This ambiguity they wholly failed to notice.

Saying the sound and color are a “potentiality” when they are not being sensed, and actualized when they are being sensed, suggests very much the same thing as Locke when he says that sensible qualities are “such qualities which in truth are nothing in the objects themselves but powers to produce various sensations in us.”

However, by using the terms of “primary” and “secondary,” and saying that sensible qualities are “nothing in the objects themselves but…”, Locke suggests that there is something especially unreal about qualities such as color and odor, as Lewis mentions in his opening paragraph. This at least is a mistake on Locke’s part, since he failed to notice that there is no huge distinction between the aspects of a body that he calls “primary” and the ones that he calls “secondary.” Just as the color of an object appears differently in different lighting and so on, so a body looks larger or smaller depending on where it is situated relative to me. Likewise an elliptical object appears to have a different shape depending on my point of view. In other words, if there is reason to think that color is “nothing but the ability to look colored,” then there is an equal reason to think that shape is “nothing but the power to appear shaped.”

And I would say that both of these are true in a certain way, and false in a certain way, just as Aristotle did about the existence of white and black. They are false, if they are taken to mean that “grass is green,” is a false statement, or that is a subjective one. It is a true statement, and an objective fact about grass. They are true, if they mean that what we know about greenness is basically what we know from sensing it, and that being green means having the possibility of being sensed in this way. And the like is equally true of shape, size, quantity, hardness, and the other aspects that Locke calls primary.

C.S. Lewis is using this as a comparison with a critical analysis of people’s thought processes. Just as analyzing the causality involved in sensation can lead someone to say that sensible things don’t have an objective existence, so analyzing people’s thought processes could lead someone to believe that nothing is true. Thus he continues:

Now this is obviously great fun; but it has not always been noticed that there is a bill to pay for it. There are two questions that people who say this kind of thing ought to be asked. The first is, are all thoughts thus tainted at the source, or only some? The second is, does the taint invalidate the tainted thought – in the sense of making it untrue – or not?

If they say that all thoughts are thus tainted, then, of course, we must remind them that Freudianism and Marxism are as much systems of thought as Christian theology or philosophical idealism. The Freudian and Marxian are in the same boat with all the rest of us, and cannot criticize us from outside. They have sawn off the branch they were sitting on. If, on the other hand, they say that the taint need not invalidate their thinking, then neither need it invalidate ours. In which case they have saved their own branch, but also saved ours along with it.

The only line they can really take is to say that some thoughts are tainted and others are not – which has the advantage (if Freudians and Marxians regard it as an advantage) of being what every sane man has always believed. But if that is so, we must then ask how you find out which are tainted and which are not. It is no earthly use saying that those are tainted which agree with the secret wishes of the thinker. Some of the things I should like to believe must in fact be true; it is impossible to arrange a universe which contradicts everyone’s wishes, in every respect, at every moment. Suppose I think, after doing my accounts, that I have a large balance at the bank. And suppose you want to find out whether this belief of mine is “wishful thinking.” You can never come to any conclusion by examining my psychological condition. Your only chance of finding out is to sit down and work through the sum yourself. When you have checked my figures, then, and then only, will you know whether I have that balance or not. If you find my arithmetic correct, then no amount of vapouring about my psychological condition can be anything but a waste of time. If you find my arithmetic wrong, then it may be relevant to explain psychologically how I came to be so bad at my arithmetic, and the doctrine of the concealed wish will become relevant – but only after you have yourself done the sum and discovered me to be wrong on purely arithmetical grounds. It is the same with all thinking and all systems of thought. If you try to find out which are tainted by speculating about the wishes of the thinkers, you are merely making a fool of yourself. You must find out on purely logical grounds which of them do, in fact, break down as arguments. Afterwards, if you like, go on and discover the psychological causes of the error.

If being “tainted” means having causes that are not completely correlated with truth, then the true answers to Lewis’s questions are that either all, or nearly all, thoughts are tainted, and no, this does not necessarily mean that they are false. Virtually all thoughts are tainted in this sense because human beings do not usually have only a single motive for things that they choose to do, and this includes the choice to believe certain things. This need not “invalidate” the thoughts because obviously it does not guarantee that the thoughts are false.

Lewis is correct that pointing out that someone’s opinions match his desires does not prove that his opinions are false. However, we saw earlier that a person’s claim is evidence for what is claimed. This will be affected, however, by a person’s motives. If a person is motivated mostly by reasons which make his claim more likely to be true, then his claim is stronger evidence. And likewise, if he is motivated mostly by things which do not make his claim more likely to be true, then his claim is weaker evidence. Consequently, if I point out that such motives are a strong factor in a person’s belief, this is not a waste of time, nor is it irrelevant. It is quite relevant, because it weakens the evidence present in his claim, and consequently it becomes more likely that the thing is actually false.

Lewis continues:

In other words, you must show that a man is wrong before you start explaining why he is wrong. The modern method is to assume without discussion that he is wrong and then distract his attention from this (the only real issue) by busily explaining how he became to be so silly. In the course of the last fifteen years I have found this vice so common that I have had to invent a name for it. I call it “Bulverism.” Some day I am going the write the biography of its imaginary inventor, Ezekiel Bulver, whose destiny was determined at the age of five when he heard his mother say to his father – who had been maintaining that two sides of a triangle were together greater than the third – “Oh, you say that because you are a man.” “At that moment,” E. Bulver assures us, “there flashed across my opening mind the great truth that refutation is no necessary part of argument. Assume your opponent is wrong, and then explain his error, and the world will be at your feet. Attempt to prove that he is wrong or (worse still) try to find out whether he is wrong or right, and the national dynamism of our age will thrust you to the wall.” That is how Bulver became one of the makers of the Twentieth Century.

I find the fruits of his discovery almost everywhere. Thus I see my religion dismissed on the grounds that “the comfortable parson had every reason for assuring the nineteenth century worker that poverty would be rewarded in another world.” Well, no doubt he had. On the assumption that Christianity is an error, I can see clearly enough that some people would still have a motive for inculcating it. I see it so easily that I can, of course, play the game the other way round, by saying that “the modern man has every reason for trying to convince himself that there are no eternal sanctions behind the morality he is rejecting.” For Bulverism is a truly democratic game in the sense that all can play it all day long, and that it give no unfair advantage to the small and offensive minority who reason. But of course it gets us not one inch nearer to deciding whether, as a matter of fact, the Christian religion is true or false. That question remains to be discussed on quite different grounds – a matter of philosophical and historical argument. However it were decided, the improper motives of some people, both for believing it and for disbelieving it, would remain just as they are.

I see Bulverism at work in every political argument. The capitalists must be bad economists because we know why they want capitalism, and equally Communists must be bad economists because we know why they want Communism. Thus, the Bulverists on both sides. In reality, of course, either the doctrines of the capitalists are false, or the doctrines of the Communists, or both; but you can only find out the rights and wrongs by reasoning – never by being rude about your opponent’s psychology.

Until Bulverism is crushed, reason can play no effective part in human affairs. Each side snatches it early as a weapon against the other; but between the two reason itself is discredited. And why should reason not be discredited? It would be easy, in answer, to point to the present state of the world, but the real answer is even more immediate. The forces discrediting reason, themselves depend of reasoning. You must reason even to Bulverize. You are trying to prove that all proofs are invalid. If you fail, you fail. If you succeed, then you fail even more – for the proof that all proofs are invalid must be invalid itself.

Lewis is himself engaging in something very like Bulverism here, or at least he is attempting to get others to do so. In the first place, the very invention of the name “Bulverism” is such an attempt. It has a ridiculous sound, and the only contribution it makes to the discussion is to make it appear that someone is doing something ridiculous. This is part of Lewis’s plan to “crush” Bulverism, namely by making people dismiss it out of hand, just as he says that they dismiss his positions out of hand.

Of course, as I already stated, Bulverism as defined by Lewis is indeed a bad thing. But this is not because a person’s motives are irrelevant, but because a person may be right despite his motives. And even if a person’s motives may weaken the evidence present in his claim, it would indeed be silly to think that the full response to an argument could be that the person does not have good motives relative to truth. If you are going to refute an argument, you should do that by discussing the matter of the argument. Lewis is quite right on this point.

Regarding Lewis’s last point in this paragraph, it is unlikely that many people actually had the intention to “prove that all proofs are invalid.” People really do have various motives for their beliefs, but this does not prove that their beliefs are false, nor does it show that their arguments do not work.

Lewis concludes the essay:

The alternative then is either sheer self-contradicting idiocy or else some tenacious belief in our power of reasoning, held in the teeth of all the evidence that Bulverists can bring for a “taint” in this or that human reasoner. I am ready to admit, if you like, that this tenacious belief has something transcendental or mystical about it. What then? Would you rather be a lunatic than a mystic?

So we see there is justification for holding on to our belief in Reason. But can this be done without theism? Does “I know” involve that God exists? Everything I know is an inference from sensation (except the present moment). All our knowledge of the universe beyond our immediate experiences depends on inferences from these experiences. If our inferences do not give a genuine insight into reality, then we can know nothing. A theory cannot be accepted if it does not allow our thinking to be a genuine insight, nor if the fact of our knowledge is not explicable in terms of that theory.

But our thoughts can only be accepted as a genuine insight under certain conditions. All beliefs have causes but a distinction must be drawn between (1) ordinary causes and (2) a special kind of cause called “a reason.” Causes are mindless events which can produce other results than belief. Reasons arise from axioms and inferences and affect only beliefs. Bulverism tries to show that the other man has causes and not reasons and that we have reasons and not causes. A belief which can be accounted for entirely in terms of causes is worthless. This principle must not be abandoned when we consider the beliefs which are the basis of others. Our knowledge depends on our certainty about axioms and inferences. If these are the results of causes, then there is no possibility of knowledge. Either we can know nothing or thought has reasons only, and no causes.

“Either we can know nothing or thought has reasons only, and no causes,” indicates that Lewis is confused.

Thoughts surely do have causes, and the efficient cause is generally the human will. Reasons and motives are both “why” people choose to believe things, and consequently are the formal aspect of that efficient cause, or in other words are final causes. It might seem a little strange to say that the fact that two and two make four is the final cause of my belief that if I have two shoes and acquire two more, I will have four shoes. But it only seems strange because we do not notice that final causes themselves come in varieties. And in any case, this is partly a question of framing. If I say, “I think I would have four shoes because to think otherwise would call into question that two and two make four,” then it is clear enough that my belief is for the sake of the truth that two and two make four.

Lewis fails to note the distinction between various types of causes, and so supposes that if thoughts have causes in an ordinary sense, they cannot have reasons, but this does not follow. Reasons are simply one of the causes that thoughts have, but they can have other causes at the same time.

Someone might say that this blog engages in a good deal of what C.S. Lewis calls Bulverism, and this concern is one of the “tainted thoughts” which led me to compose this post. Thus I summarize my response to this concern:

More or less all claims are affected by motives other than truth. But this is not irrelevant, because some claims are more affected by such motives than others, and to the extent that this is the case, this weakens the evidence contained in those claims. Thus I would not consider it irrelevant even if I point out someone’s motives without proving directly that he is mistaken.

Nonetheless, in practice I do not usually do this. Generally if I think that someone is wrong, I will argue this directly, and only reveal someone’s motives in addition, which even Lewis concedes can be relevant in that situation.

There is one possible additional objection, which Lewis does not formulate explicitly, but which he indicates when he says, “The modern method is to assume without discussion that he is wrong and then distract his attention from this (the only real issue) by busily explaining how he became so silly.” The objection would be that whether he is right or wrong is “the only real issue.” So even if you first argue that someone is wrong, proceeding to discuss his motives is inappropriate, since it is no part of the issue, and it seems merely insulting.

I disagree that whether someone is right or wrong is the only real issue. As I have stated before, I do not think I really understand someone until I understand why he says what he does. And real people do not only have reasons for their beliefs, but motives as well. So in order to understand someone as well as possible, it is necessary to know not only his reasons, but also any other motives that he has.

But since people rarely notice their own motives, this suggests that I am saying that frequently people do not even understand themselves. And this is quite true, and in this way St. Paul says that some have “turned to meaningless talk, desiring to be teachers of the law, without understanding either what they are saying or the things about which they make assertions.”
