(In reply to Tracy's mail [below] regarding the football coach who used statistics). Tracy, there are several points that your mail raises. This reply is only concerned with the Paul Brown example. Let's imagine two coaches: one who keeps stats on his or her players (and looks for trends), and another other who doesn't. Let's call one Paul Brown and the other Phil Jackson. For simplicity's sake, let's assume both are coaching the same sport (football). Note that the issue isn't whether one of the coaches sees patterns or trends -- for surely they both do. The issue, rather, is what kind of cognition (or personality type) one relies upon to make sense of the activity. One doesn't need stats to see the dynamic nature of Jim Brown. Many experts could see the trends in production that your stats purport to show simply because they have developed "a trained eye." That is, they have developed "connoisseur sense." In fact, by the time one becomes a connoisseur, they have ascended to the point where they can see through (or govern) stats. (See Wittgenstein on aesthetics, "seeing as" and imponderable evidence). Here's what the issue boils down to: what are you using the stats for? If the answer is for memory, this says more about psychology than it does epistemology. If the answer is "analysis," this suggests that the logic of judgment is beyond our control for some reason. This is fine when humans lack judgmental capacity for some reason -- when information is poor, e.g., or when we ourselves are simply not connoisseurs of the activity. As I said before, statistical analysis is best when our experience and perception of the thing in question is poor. If I knew nothing of football, I would indeed want to know what a rushing average was for X before I decided to place him or her in the game. Just take a look at fantasy football: that's what the entire activity is (who's better at making those judgments). But if I'm a connoisseur, the rushing average is something that looks to ME for correctness. I say what is significant (or not) about it. I can tell you its flaws and why it either does or does not correctly report the happenstance. And so, my sense is that the Paul Brown stuff is more relevant to personality type than to the secret of coaching. In fact, I don't know if you realize this, but your argument seems to be an endorsement for analytic formalism. What is more important to knowing: analysis or meaning? For a period of time in philosophy, people thought analysis was king. Wittgenstein showed us, however, that meaning is more important. Wittgensteinians are anti-formalistic across the board -- we dislike it as much in language as we do numbers. Wittgenstein didn't change course: he simply transcended analyticity. It's like the moth turning into the butterfly. Culture is what ultimately is king. This doesn't mean analysis or formalism is bad; it only means that it can never be unto itself. It's always there as a servant. Politics is no different from football. Those who think that quantitative statistical analysis of behavior reveals "the truth" are no different than those who understand football as a fantasy league. (Or those who say, e.g., "the numbers tell you that you must run the ball more than 12 times to win in the Super Bowl"). The real masters are those who have fostered a acute connoisseur sense and who, therefore, have a keen eye for the aesthetic. These people will tell you when it's time to stop running. (I'll send one more mail tomorrow that address your other points) Regards and thanks. (P.S. -- sent to Wittrs) Dr. Sean Wilson, Esq.

Why did Paul Brown always see that Jim Brown carried the ball twice as much as Leroy Kelly, despite that indisputable fact Kelly was a great running back? Because Brown, probably the most data driven coach in football history (and, coincidentally, one of the greatest) kept stats and knew that Brown was more likely to a) carry the ball for a higher average and b) consistently get more long runs. He also knew that Frank Ryan was consistently better throwing the ball when Brown had the other side occupied. Was this something he could see in games? Sure, but the deciding factor was the stats, just like it is for almost every winning football coach in the business these days. I'm sorry, but it simply isn't true that our perceptions can deliver the same kind of information as a careful analysis of data can. Also, the experience of researchers is not the final check on the analysis; the data is. The hallmark of good scientific work is that it is counterintuitive. 2. Most "facts" in most sciences are, at bottom, stochastic. That's why our perceptions are less use then we usually think. As to "constructing what you show": all sciences do that. The stochastic nature of events forces us to impose an order on them in order to understand them. This does not compromise the picture; it creates it and makes it useful. Ludwig was good on this point, but I doubt he would have gone as far as you have here. 3. Surely you aren't claiming that certain states of affairs are easier to "scientize" then others? Now we are straying into an area where the actual character of science is being mythologized. Different states of affairs require different kinds of science. What you seem to be claiming here (if I'm not mistaken) is that there is only one kind of science: what Freeman Dyson calls "Athenian" science. That isn't the case. The scientific method must be applied differently in - say - meteorology, quantum mechanics, and political science since the subjects analyzed and the purposes of the analysis differ so greatly. But it is still recognizable as science in each of these fields. As to the methods used, I'm as leery of the maths as the next guy, but only because parsing out of errors is important to know what the models tell us. As to the rest, GBS put it best, "If experience was the only teacher, then the stones of London would be wiser than the wisest man." Well, enough.
