HOW DOES THE BRAIN GENERATE COMPUTATION?

[12.2.01]

"For humans, Chomsky's insights into the computational mechanisms underlying language really revolutionized the field, even though not all would agree with the approach he has taken. Nonetheless, the fact that he pointed to the universality of many linguistic features, and the poverty of the input for the child acquiring language, suggested that an innate computational mechanism must be at play. This insight revolutionized the field of linguistics, and set much of the cognitive sciences in motion. That's a verbal claim, and as Chomsky himself would quickly recognize, we really don't know how the brain generates such computation."

THE COMPUTATIONAL PERSPECTIVE

Daniel C. Dennett
[11.17.01]

"There are going to be things that meet those conditions that are not interestingly computational by anybody's standards, and there are things that are going to fail to meet the standards, which nevertheless you see are significantly like the things that you want to consider computational. So how do you deal with that? By ignoring it, by ignoring the issue of definition, that's my suggestion. Same as with life! You don't want to argue about whether viruses are alive or not; in some ways they're alive, in some ways they're not. Some processes are obviously computational. Others are obviously not computational. Where does the computational perspective illuminate? Well, that depends on who's looking at the illumination."

SOFTWARE IS A CULTURAL SOLVENT

How Our Artifacts Will Be Able To Interact With Our Biological Forms
Jordan Pollack
[4.10.01]

"I work on developing an understanding of biological complexity and how we can create it, because the limits of software engineering have been clear now for two decades. The biggest programs anyone can build are about ten million lines of code. A real biological object — a creature, an ecosystem, a brain — is something with the same complexity as ten billion lines of code. And how do we get there?"
