I've seen there's discussion on LW about rationality, namely, about what it means. I don't think a satisfactory answer can be found without defining what rationality is not. And this seems to be a problem. As far as I know, rationality on LW does not include systematic methods for categorizing and analyzing irrational things. Instead, the discussion seems to draw a circle around rationality. Everyone on LW is excepted to be inside this circle - think of it as a set in a Venn diagram. On the border of the circle there is a sign saying: "Here be dragons". And beyond the circle there is irrationality.
How can we differentiate the irrational from the rational, if we do not know what the irrational is?
But how can we approach the irrational, if we want to be rational?
It seems to me there is no way to give a satisfactory account of rationality from within rationality itself. If we presuppose rationality is the only way to attain justification, and then try to find justification for rationalism (the doctrine according to which we should strive for rationality), we are simply making a circular argument. We already presupposed rationalism before trying to find justification for doing so.
Therefore it seems to me we ought to make a metatheory of rationality in order to find out what is rational and what is irrational. The metatheory itself has to be as rational as possible. That would include having an analytically defined structure, which permits us to at least examine whether the metatheory is logically consistent or inconsistent. This would also allow us to also examine whether the metatheory is mathematically elegant, or whether the same thing could be expressed in a simpler form. The metatheory should also correspond with our actual observations so that we could figure out whether it contradicts empirical findings or not.
How much interest is there for such a metatheory?
I think the most you can hope for is a model of rationality and irrationality that can model mysticists or religious people as well as rationalists. I don't think you can expect everyone to grok that model. That model may not be expressible in a mysticist's model of reality.
Irrationality is just less instrumentally rational - less likely to win. You seem to have split rational and irrational into two categories, and I think this is just a methodological mistake. To understand and compare the two, you need to put both on the same scale, and then show how they have different measures on that scale.
Also, now that I look at more of your responses, it seems that you have your own highly developed theory, with your own highly developed language, and you're speaking that language to us. We don't speak your language. If you're going to try to talk to people in a new language, you need to start simple, like "this is a ball", so that we have some meaningful context from which to understand "I hit the ball."
Quickly thereafter, you have to demonstrate, and not just assert, some value to your language to motivate any readers you have to continue learning your language.
Agree. The Pirahã could not use my model because abstract concepts are banned in their culture. I read from New Scientist that white man tried to teach them numbers so that they wouldn't be cheated in trade so much, but upon getting some insight of what a number is, they refused to t... (read more)
