If you happen to know about evolutionary peaks, good. If not I will briefly try to explain it though it is best if you know about evolutionary theory.

An evolutionary peak is a possible genome in the vicinity of which there is no other more fit genome. All mutations that could happen would result in a less fit genome (i.e. genes that replicate less than the genes in the peak genome). If evolution reaches a peak, it will stay there as it does not ‘have foresight’ (or ‘sight’) to move down the hill to another and higher peak even if there is one relatively nearby. Evolution is blind. The genome is evolutionary stable once at the hill. This continues until a change in the environment happens and another genome becomes more fit. Then evolution continues to change the genome to whatever is more fit. It is rare that a mutation occurs and thus gives evolution an opportunity to evolve change the genome into a more fit one. Evolution takes lots of time. It is even more rare that multiple mutations arise at a time.

Consider now webs of belief. A person’s web of belief is the entirety of all his beliefs. A web of belief may be more justified/warranted/better than another web of belief for a number of reasons (simplicity, coherency, lack of contradictions, mutual support, etc.). A person may change (at will but not completely free at will) his web of belief by changing its parts, either one belief at a time or many beliefs at a time. It is rare that a person changes his belief, if it is in the middle of his web of belief (=connected with many other beliefs). It is even more rarely that a person changes a lot of beliefs at one time.

The analogy is this:

Part of evolution Part of web of belief
Genome Web of belief
Fitness Justifiedness, warrantedness, goodness
Mutation Change in belief
Evolutionary peak The web of belief that is more justified than all other nearby webs of belief

Do you see the analogy? It is quite interesting I think. Similarly to evolution not having ‘foresight’/'sight’, most people do not have the necessary foresight/sight to see that another web of belief although a bit away from their current web of belief is better than their current one. And if they are at a peak or close to a peak, they will not move towards a higher peak if it is a bit away and they only change a few belief at a time. In a way it is rational to change one’s web of belief toward the nearest peak one can spot. Though ultimately it is more rational to try to spot the highest peak and then move towards it. But it is so hard to spot the highest peak (=discover which web of beliefs is the best), that we for all practical purposes cannot do so and thus stay near a local web of belief. Further, it is not humanly possible to discover with a high degree of certainty which webs of belief are the peaks and which are not. There is no known formula in which one can input all one’s beliefs (there are too many of them too) and in the output is the web of belief’s goodness rating.

But if we cannot do this with much certainty, how should we be able to say that another person has a worse web of belief than we have with much certainty? We cannot. Though we can do rough analyses and make somewhat justified claims about other people’s webs of belief. It is vary hard if not impossible for two rational and sophisticated people to discover which of them has the best web of belief. If their webs of belief are very different and are both near a local peak, then there is no way for one of them to move towards the other while continuously getting a better web of belief. He would need to change many/a lot of beliefs at once, and this very rarely happens. Arguments usually only change a single/small number of belief(s) in a person at a time. What would need to be done to change one’s web of belief so drastically, rationally, is an evaluation of all relevant arguments ‘viewed’ from both webs of belief. In the case of atheism/theism, doing so will take at least several years. It would be much better if one simply found oneself closer to the atheism peak to begin with (I did), or changed to moving toward the atheism peak without first moving towards the theism peak. But then, a person who happened to be a theist (because of, say, his parents) would most probably first move towards the theist peak than the atheist peak. That is the most rational way given a conservative principle like “change as little beliefs at a time as possible to continue gaining a better web of belief.”.

Still, given the above, I’m relatively sure that, say, a thomist (in fact it was a thomist that inspired me to write this essay) has a worse web of belief than I do and that the highest thomism peak is much lower than the highest atheism peak. But I should not claim much certainty about this.

Kennethamy:

What is it for something to be logical?

So many threads ask whether this or that is logical. Is probability logical? Are moral arguments logical? And so on. I never know what it is being asked by such questions. Is there something clear and specific that is being asked by the question, is X logical? What is it?

Emil [Reply to Kennethamy]:

I feel the same way.

Fast [Reply to Kennethamy]:

I think “logical” is being used in different ways. Here’s a little brainstorming:

Sometimes, it’s just a synonym for “reasonable.” A wet ground was a logical consequence of rain. Hence, it was reasonable to expect a wet ground given that it was raining.

Someone who takes a systematic approach to solving a problem may be said to be approaching a problem logically.

A valid argument (even if the premises are false) may be considered a logical argument.

Also, it may be used to differentiate. She just randomly looked through the hey in search of the needle, but he was very methodical as he took a logical approach.

Kennethamy [Reply to Fast]:

Is there nothing in common in all these different uses of “logical”? Why, then, do we use the same term?

Kroni [Reply to Kennethamy's first post]:

Maybe they’re asking if it can be identified through premises and conclusions…Or maybe they are trying to figure out if abstract concepts like morality follow some kind of mathematical pattern or have a logical purpose for existing.

Emil [Reply to Kroni]:

What does “logical purpose” mean?

Kennethamy [Reply to Emil]:

I imagine it might be asking whether the purpose is something that can be accomplished, or whether the purpose is worth accomplishing. The trouble is that it can mean so many different things that the question, is it logical? does not convey anything really being asked.

So, rather than simply ask whether X is logical, why not, instead, ask about the problem you have in mind when you asked the question. And, maybe if you think about what the problem is, and cannot come up with anything specific or clear, maybe you will wait to ask the question, or maybe not ask the question at all.

Emil [Reply to Kennethamy]:

Basically the analytic principle of questions. Always start by analyzing the question.

The Principle

This is a principle worth noting and it seems to be a general principle followed by those that are analytic thinkers or philosophers. When posed with some question that one cannot quickly answer or does not quickly see a way to answer in principle, then analyze the question. For it is often the case that it is the question that there is something wrong with. It may be vague, unclear or otherwise misleading.

And perhaps also: Don’t ask questions that are vague or unclear. At least in philosophical contexts.

Philosophy as a Blood Sport

Preface

This essay was written for a Festschrift for David Zimmerman, on the occasion of his fiftieth birthday.

Festschriften are, by custom, celebratory in nature. And so I must ask indulgence in my offering this somber, downbeat, essay. I am sure that David will not take it amiss. It is certainly not my desire to rain on David’s parade. Indeed, knowing of his intense sense of fairness, I suspect that he might even agree with some of what I have written. In any event, I have been talking about these matters with several colleagues in the Department over a period of many months, and it is time I put some of this in writing. This Festschrift provides only the occasion. I assure everyone that I had no particular philosophers, save the one faulted in the first paragraph, in mind when I wrote it.

It was back in the spring of 1965. I was a graduate student at Indiana University and the Western Division of the American Philosophical Association was holding its annual convention in Chicago. I and a few of my classmates drove from the campus at Bloomington to Chicago for the weekend meetings. At those meetings I witnessed the rudest, the most ill-mannered, performance I have ever seen by a philosopher. Robert Imlay read a paper, “Do I Really Ever Raise My Arm?” G*** B*** was in the audience. Immediately when Imlay had finished speaking, B*** was on his feet, usurping the meeting’s Chair of his scheduled role. B*** fumed: “You have got it all wrong. I am going to tell you what you should have said. Then, when I have said that, I will leave this room because I do not care how you will reply.” Whereupon B*** did just as he announced. He gave an impromptu talk of a few minutes, standing at his place in the audience, and then he turned and strode out of the room. Grover Maxwell, who was chairing the meeting, recovered admirably, and – pretending that none of this had happened at all – said, eloquently, “And now let us begin.”1

To this young graduate student, terribly naive about professional courtesies and mores, the incident was, although incredible, not particularly disturbing. It was titillating; it had a taste of scandale.

But with the perspective acquired over more than twenty-five ensuing years, having been involved both as spectator of, and participant in, numerous further public exchanges between philosophers, I now see that spontaneous piece of theater not as an isolated aberration but, sorrowfully, as only my first exposure to a number of such incidents.

Philosophers, of course, are supposed to be critical. We have trained, and daily refine our skills, at exposing the errors in others’ work. But while the exposing of error is an essential part of the doing of philosophy, it is not all there is to doing philosophy. Far too much of the practice of philosophy, both written and dialogical, has become one-sided: finding what is wrong in someone else’s work and failing to find what is right, useful, and meritorious in that work.

It is revelatory to attend the colloquia of academics and researchers outside of philosophy. The ambience is often, indeed almost invariably, radically different from meetings of philosophers. Philosophers have much to learn from those examples.

I remember when as an undergraduate, a year before I was to switch my career to philosophy, I took a summer job at the General Electric Research Laboratory, a scientific mecca which, at that time at least, was the largest privately funded research lab in the world. Every Friday afternoon there was a visiting researcher scheduled to deliver a talk in the auditorium explaining his latest research.2 These sessions were well-attended and keenly anticipated. The discussions following the talks were animated and exciting. And they were totally unlike much of what I have experienced in philosophy. To the best of my recollection, there was not a single instance at GE of anyone’s ever challenging the speaker on anything said. Instead these sessions were made up entirely of replies of this nature: “I’m working on such-and-such. Do you think I could adopt your techniques for what I am doing?”; or, “I think I can help you with so-and-so aspect of your problem. Let’s get together on this.”; or, “Have you heard of x’s results (/techniques)? I think his results (/techniques) could be useful to you.”; etc.

In other words, the discussions were invariably, and wholly, given over to trying to enhance, and make use of, one another’s work, to a cooperativeness, and selflessness that was natural, easy, and uninhibited. No one tried to ‘score any points’ off anybody else; no one tried to attack any other person’s work.

Since then I have witnessed the same friendly collegiality numerous times among other academics, and by ‘other’ I mean ‘non-philosophers’. Granted there have been occasions when I have seen philosophers behave in a similarly admirable manner. But I have also seen too many occasions when philosophers have ‘gone for the jugular’.

Is the blood lust I am speaking-of the cause of the underrepresentation of women in our profession? Does our very manner – collectively speaking of course, there are many individual exceptions – of doing philosophy repel the gentler, kinder, souls among our students? Have we adopted a collective personality which perpetuates itself by driving away those students who do not share our aggressiveness? These questions are, of course, sociological ones, ones whose answers call upon empirical research, and – as philosophers – we do not much ourselves conduct empirical research. But we must not fall back upon a priori answers.

As a father of a daughter who is pursuing a Ph.D. degree in philosophy, I have been afforded a rare opportunity to see academic philosophers from the outside, through someone else’s eyes. But it is not just, or even especially, Diane’s views which have troubled me. It is, rather, that she has been the catalyst for my seeking to learn from my own students how they view philosophers and, along with that, the contemporary practice of philosophy. Many of my women students, having finally been invited to offer their opinions and to relate their experiences, have been forthcoming. And what stories I have heard.

What so many persons currently practicing philosophy, currently serving as role models and mentors to students, find exhilarating – the cut and thrust of verbal battle – antagonizes, indeed offends, many students. Colloquia are viewed by these students – especially women – as the academic counterparts of courtroom battles. (Is there something of F. Lee Bailey, Louis Nizer, and Melvin Belli in many of us?) My students tell me that there is a palpable feeling of combat in philosophy paper readings and colloquia. And with their having alerted me to it, I, too, have come to sense it. Moreover, certain anecdotal evidence suggests that aggressive challenging of guest speakers’ theses has chilling effects on many of our students. For example, my best student of a year or two ago, a student with a real flair for philosophy, told me that she wanted no part of the hostility she felt at colloquia, and, despite my trying to convince her otherwise, was determined to leave philosophy. So far as I know, she has.3

It is not only in meetings. I find something of the same ruthlessness in many journal articles, and to an even greater extent in the reports that journal referees write about others’ work. I have, in various capacities, had opportunity to read a fair number of referees’ reports. Many of them leave me incredulous. What is there about writing an anonymous report on another’s work that empties the spleen of so many philosophers? Time and again, I have had to edit referees’ reports so as to make them, simply, civil. (Steven Davis, who sees far more referees’ reports than I do, has told me that he, too, finds many of them outrageously hostile.)

I am not remotely suggesting that we not attend to, still less desist from, the uncovering of error in philosophical work. But there are ways of doing this that are humane and honorable, and other ways that are insulting and unseemly. A person’s stature as a philosopher is not diminished by generosity and sensitivity. One thinks, for example, of Carl Hempel. Those who have known him personally (I have not) invariably speak of his kindness, and that humanity reflects in his writings: we look in vain there for a ‘put down’ of other philosophers. In Hempel’s work we see how it is possible to do philosophy extremely well without savagery. (Happily many other names come to mind as well.) But, by and large, or at any rate, to a greater extent than is warranted, philosophy has a vicious streak. If we really care about our profession, we need to reverse its destructive tendencies.

To be sure, what I have expressed here are opinions. You well may disagree with me. But if you are inclined to dismiss what I have written, do try to elicit views from students, not just those who have cast their lot with us, viz. the senior undergraduates and graduates, but from beginning students, most of whom abandon philosophy courses after initial exposure. It is easy to explain the attrition as being due to students’ inability to meet the high standards of the profession. But ought we to be sure that that is the principal reason? Might there be something else which disaffects students? Something not about philosophy itself, so much as about philosophers themselves?

Selected readers’ comments.

Notes

  1. Robert Imlay recalls the incident exactly as I do and has provided me with some additional information. It turns out that the meeting was the first time Imlay had ever read a paper in public. To this day, he regards B***’s onslaught as the most traumatic episode of his professional career.
  2. This was the early 1960s. I do not recall even one woman as guest speaker that entire summer.
  3. There is as well a significant further category of loss. Susan Wendell speaks of this in a note (25/07/92) she wrote me on reading a draft of this paper: “In addition to the consequences you point out, I think that the performance-under-fire aspect of presenting and hearing papers gives our students a false picture of philosophy. After all, a philosophic position is not proven false just because Jane Q. Philosopher can not instantly think of a good rebuttal to a criticism from the audience, nor is Jane thus proven to be a bad philosopher. Unfortunately, uncharitable opinions of precisely these sorts often are fostered in such circumstances. Even what looks to be a devastating criticism is sometimes seen to be smoke-and-mirrors after a few hours of hard thought. Many students, however, come to value the quick and clever point too highly. I have seen too many smart alecks, who have no significant ability to listen, produced by a philosophical education.”
