Is Tillers Part of a French Revolution?


Is Tillers on the edge of the cusp of a French revolution, an epistemological revolution with American rivulets?

I sincerely hope not!

Just four days after giving a talk called A Rube Goldberg Approach to Factual Inference in Legal Settings, I awakened to a New York Times report that some French cognitive scientists are propounding what they call an "argumentative" theory of reasoning, according to which "lack of logic and other supposed flaws that pollute the stream of reason are instead social adaptations that enable one group to persuade (and defeat) another." In the course of describing this theory the article refers some theorists' views that the brain is a conglomerate of Rube Goldberg contraptions.

I have been musing for some time about the mind's conscious inference procedures as a collection of devices that resembles a Rube Goldberg process. But I would like to say here & now that my take on the seemingly irrational nature of the mind's mechanisms differs sharply from some of the views reported in the newspaper article:
First, I reject an unadulterated consensus theory of truth. (We have had enough of that sort of thing.)
Second, I deny that the evidence marshaling methods I discuss and their interaction are irrational. I say that the interaction of those methods is to a substantial extent mysterious (which is a different claim), that the subconscious workings of the brain determine the interactions of such conscious evidence marshaling strategies, that these non-explicit mental operations connecting the explicit evidence marshaling methods to each other have a lot of rationality to them, and that tools can and should be devised that make some of these tacit mental operations become more explicit and perhaps work better than they presently do.

Rube Goldberg and Factual Proof in Legal Settings

My abstract for a One-Day Workshop on AI & Evidential Inference in Conjunction with ICAIL 2011, Pittsburgh, Pennsylvania, June 10, 2011:

Peter Tillers, "A Rube Goldberg Approach to Fact Investigation, Evidential Inference, and Factual Proof in Legal Settings"

There is no single logical or analytical process that characterizes effective human deliberation about ambiguous, incomplete, and inconclusive evidence about facts. Some or many of the early proponents of AI knew this: They knew or believed that intelligent creatures -- like those who possess mechanisms like our neural brains -- have a variety of distinct information processing mechanisms (e.g., sensory mechanisms, mechanisms for storing sensory data, etc.) that are clumped together and that, taken together, somehow manage to generate sweet inferential and epistemic music. The work that I did with David Schum led me to an analogous conclusion: Investigating factual hypotheses and drawing inferences about factual hypotheses involve a variety of disparate marshaling processes that, despite their distinctiveness (or, perhaps one might even say, incommensurability), work together in a way not specifiable by any kind of recipe or strict logic to produce elegant and frequently accurate factual inferences. However, it does not follow and it is not true that structured deliberation about evidence is pointless.
