The Fear of Reason: In defense of rational argument

by Leon Wieseltier

New Republic
June 23, 2011

“I just want to point out,” declared the student at the far end of the seminar table, “that when Maimonides offers a proof of God’s existence, he is not saying that he has really proved it. What he’s saying is: This works for me, and if it works for you, great.” I was teaching a graduate seminar on The Guide of the Perplexed at a fine American university, and I was pleased to see my students warming to my insistence that the old masterpiece is still alive, and one of the most formidable obstacles ever erected against a thoughtless existence. We returned repeatedly to the question of what medievals can teach moderns about the indispensability of a worldview, and about the proper methods for justifying one. But the young man’s comment about the subjectivism of Maimonides’s proof—anyway the least interesting part of the book--startled me. It was so American and so wrong. After explaining why it was not just historically correct, but also philosophically respectable, to conclude from the text that its author really could have believed that a proof was possible, I proposed that we quit the twelfth century and put a little pressure on the talismanic words “and if it works for you, great.” I began a discussion of the shortcomings of pragmatism, which allowed me to launch into a withering—and of course intellectually devastating—analysis of the ideas of Richard Rorty and their poisonous impact upon thinking in America. My students offered surprisingly little resistance; but then they had signed up for a winter of rationalism and religion--this countercultural band was not ashamed of its interest in the idea of truth. Yet the Rortyan shrug was still there in the young man’s comment, and so I asked him for his opinion about reason. He said that it frightened him and discouraged him. The problem with reason, he explained, was that it claimed to settle matters once and for all, and that this was arrogant, and that it left him with nothing more to say. Rationalism made him feel excluded and late. I replied that he had it backward. It is not reason, but unreason, that shuts things down. You cannot argue against an emotion, but you can argue against an argument. That is why we were still contending with Maimonides, and why he was still contending with Aristotle. A reasoned discussion is always open and a reasoned intervention is always timely. Unreason is more arrogant, more impatient, more cruel, than reason. Since reason is general, it is inclusive. Reason, I said, is strict but fragile, forever hounded, forever distracted, the minority cause, provisional, fair, curious, fallible, public—not tyrannical but heroic, in its lonely insurrection against the happy and popular hegemony of passions and interests. I told my students about Maimonides’s life, the persecution, the tragedy, the depression, the paranoia, so that they would see the creatureliness of the rationalist, and honor his confidence in the mind as a human triumph. Reason is even poignant.

Extraverts More Likely to Believe in Free Will

Miller-McCune
June 8, 2011

Philosophers’ views on freedom and moral responsibility are influenced by inherited personality traits. If they can’t be objective, can anyone?

Philosophers are trained to think things through logically and reach conclusions based solely on reason. But as science provides increasing evidence for the interconnectivity of mind, body and emotions, is that sort of intellectual objectivity truly possible?

A newly published study suggests the answer is no — at least when it comes to addressing one fundamental issue. It finds deep thinkers with a specific type of personality — warm and extraverted — are more likely to believe that free will remains a viable concept, even in the light of research suggesting our behavior is largely determined by unconscious impulses.

While this may sound like a theoretical argument, the researchers, led by Eric Schulz of the Max Planck Institute for Human Development in Berlin, argue it has potentially profound implications. If expert opinion is partly a matter of personality, it negates the notion that trained specialists can and do provide cool, clear-minded assessments of the facts — a concept that is at the foundation of our legal system.

“Even highly skilled professionals such as lawyers, judges, ethicists and philosophers may not be immune to the influence of their different personalities,” they write in the journal Consciousness and Cognition. One could easily add other experts to that list, including economists, sociologists — and journalists.

Rational After All: Toward an Improved Theory of Rationality in Economics

by Yulie Foka-Kavalieraki and Aristides N. Hatzis

Revue de Philosophie Economique
Vol. 12, No. 1, June 2011

In this paper we critically review the literature on rational choice theory (RCT) and the critical approaches to it. We will present a concise description of the theory as defended by Gary Becker, Richard Posner and James Coleman (as well as others) at the University of Chicago from the mid-1970s to the early 1990s, we will discuss its epistemological assumptions and predictions and we will also examine the most important arguments against it. We will give our main emphasis on the critique coming from behavioral economics and we will try to see if humans’ supposed cognitive constraints lead to a failure of rationality or if they constitute rational responses to the scarcity of information, time and energy. In our discussion we will use findings from experimental economics and the sciences of the brain, especially evolutionary psychology and neuroeconomics. Our intention is to present an improved theory of rational choice that, informed from the above discussion, will be descriptively more accurate but without losing its predicting power. Moreover, we will conclude by trying to answer the most important related policy question: when rationality seems to fail, does this necessarily imply that agents should be paternalistically protected against themselves? We will briefly defend the thesis that, in the long-run, it is much better for them and the society at large for the individual decision makers to be let alone to develop rational responses to their cognitive constraints.

On ‘Jeopardy!’ Women Take Fewer Risks vs. Men

Miller-McCune
June 2, 2011

A study of contestant behavior on the popular game show “Jeopardy!” suggests women tend to hedge their bets when facing male opponents.

The answer is: It’s a game show that provides surprising clues about sex, social rules and risk-taking.

And the question is: What is Jeopardy!?

Two Swedish researchers, writing in the journal Economics Letters, report an intriguing pattern of behavior by contestants on the popular quiz program. Women, it seems, take fewer risks when their Jeopardy! opponents are men.

Gabriella Sjogren Lindquist and Jenny Save-Soderbergh of the Swedish Institute for Social Research looked at 206 episodes of Jeopardy!, focusing on those moments when one of the three contestants must decide how much to wage on a Daily Double.

For those unfamiliar with the Jeopardy!, Daily Doubles pop up at random during the course of play. Rather than wagering a set amount on whether they will know the answer to a question (the show’s usual format), contestants are given the opportunity to bet as much or as little as they like, up to the amount of money they have accumulated to that point.

The researchers tallied the results of 615 Daily Doubles, featuring 251 male and 65 female contestants. (The same contestant can play several Daily Doubles during the course of the show, and still more if he or she wins and returns the next day.)

The researchers found “no systemic gender differences in performance,” either on the Daily Double questions or the final scores. But they also determined that “male players are more likely to give the correct answer when competing against males only.” Perhaps man-to-man competition, which played a vital role in our evolutionary past, sharpens the male mind.

Most intriguingly, the researchers found females “apply a more conservative wagering strategy” when their two opponents are both male. Compared to instances when they’re up against two women, or a man and a woman, “Women wager 25 percent less of their accumulated score on average” when they’re competing against two men.

“Men do not display this behavior,” they add.

"Athene's theory of everything"....


Αν και αμφίβολης αποδοχής του συγκεκριμένου "ερευνητή" από την επιστημονική κοινότητα, το βιντεάκι αυτό έχει προκαλέσει αρκετό ντόρο στο διαδίκτυο. Πρόκειται για τον Chiren Boumaaza γνωστό και ως Athena (έμαθα ότι έχει υπάρξει δεινός και "ανίκητος" παίχτης του world of warcraft προτού εξαφανιστεί από την ιντερνετική αυτή κοινότητα για να αφοσιωθεί πλήρως στη συγκεκριμένη έρευνα). Υπάρχει και σχετικό blog: athenism.net το οποίο συστήνεται ως "scientific research & self-development activism".

Αναφέρεται σε Einstein's theory of relativity, quantum mechanics & consciousness, neurons, Joseph E. LeDoux, De Broglie equasion κ.α.... και υποστηρίζει ότι "δεν μπορεί να υπάρξει "ελεύθερη επιλογή" ενόσω είμαστε συναισθηματικά συνδεδεμένοι σε ένα σύστημα ιδεών (belief system). Το ερώτημα δεν είναι αν τα πιστεύω μας είναι σωστά ή λάθος αλλά αν το να είμαστε συναισθηματικά δεμένοι με αυτά μπορεί ή όχι να μας ωφελήσει....."

Ο λόγος που το αναρτώ είναι κάποια επιχειρήματά του που αν και δεν έχουν επαληθευτεί, ίσως να γίνουν τροφή για σκέψη για κάποιους από εμάς. Κυρίως όμως με προβλημάτισε το εξής σχετικά με την ίδια την ύπαρξη αυτού του video: Ένας επιστήμονας ερευνητής με αντικείμενο που από τη φύση του προκαλεί πολύ ενδιαφέρον και αντιπαραθέσεις, δημοσιεύει στο ευρύ κοινό (δηλ. όχι ακαδημαϊκή/επιστημονική κοινότητα) τις υποθέσεις ή τα μη επαληθεύσιμα (ακόμα ίσως) επιχειρήματα και συμπεράσματά του (έστω και αν η δημοσίευση γίνει μέσω τρίτου, όπως εν προκειμένω); και αν το κάνει, αυτό γίνεται για να προκληθεί ντόρος ή μήπως πλέον σήμερα η επιστήμη και η διαδικασία της έρευνας (υπόθεση, πείραμα, επιχείρημα, επαλήθευση κλπ) γίνονται "ανοιχτές" και στο μη ακαδημαϊκό κοινό (κυρίως με τη βοήθεια του internet); Τί κινδύνους ή ωφέλειες μπορεί αυτό να σημαίνει;;

Για όσους δεν διαθέτουν πολύ χρόνο να το δουν, προτείνω τα 7:30'...12'...21'...25'...42:40'...44'...47'....
