On intelligence

February 8, 2007

Consider my auto-repair man, again. He had a habit of telling me jokes whenever he saw me. One time he raised his head from under the automobile hood to say: “Doc, a deaf-and-mute guy went into a hardware store to ask for some nails. He put two fingers together on the counter and made hammering motions with the other hand. The clerk brought him a hammer. He shook his head and pointed to the two fingers he was hammering. The clerk brought him nails. He picked out the sizes he wanted, and left. Well, doc, the next guy who came in was a blind man. He wanted scissors. How do you suppose he asked for them?”

Indulgently, I lifted by right hand and made scissoring motions with my first two fingers. Whereupon my auto-repair man laughed raucously and said, “Why, you dumb jerk, He used his voice and asked for them.” Then he said smugly, “I’ve been trying that on all my customers today.” “Did you catch many?” I asked. “Quite a few,” he said, “but I knew for sure I’d catch you.” “Why is that?” I asked. “Because you’re so goddamned educated, doc, I knew you couldn’t be very smart.”

And I have an uneasy feeling he had something there.

From Isaac Asimov‘s What is Intelligence, anyway? (via MTA).

On systems approach to biology

February 8, 2007

Nature is running a web focus called Connections:

From cell biologists to quantum physicists, researchers are struggling to work out how systems involving large numbers of interacting entities work as a whole. In this collection of Essays, scientists explain how a systems approach, in parallel with the reductionism that dominated twentieth-century science, promises to yield fresh insight, and in some cases, to challenge the most widely held concepts of their field.

This editorial explains the idea behind the series. Two essays have been published in the series so far. While this essay calls for

a revision of such concepts as organism, species, and evolution itself,

this one argues that

By its very nature, life is both contingent and particular, each organism the product of eons of tinkering, of building on what had accumulated over the course of a particular evolutionary trajectory. Of course, the laws of physics and chemistry are crucial. But, beyond such laws, biological generalizations (with the possible exception of natural selection) may need to be provisional because of evolution, and because of the historical contingencies on which both the emergence of life and its elaboration depended.

Take a look!
