Top-Down Engineering of AI

The philosophers’ fascination with propositions was mirrored in good old-fashioned AI, the AI of John McCarthy, early Marvin Minsky, and Allen Newell, Herbert Simon, and Cliff Shaw. It was the idea that the way to make an intelligent agent was from the top down. You have a set of propositions in some proprietary formulation. It’s not going to be English—well, maybe LISP or something like that, where you define all the predicates and the operators. Then, you have this huge database that is bea...

 Teaching Children About Death

In a discussion on my blog regarding teaching kids about death, one of my readers commented that he uses a book called Lifetimes, by Bryan Mellonie. He explained that the book describes the lifetimes of various living things and focuses on the life that happens in between birth and death. He explained, “I tell my kids that they do continue, not only in the life matter and lineage cycle, but as part of the world/universe per se. ‘The world produced life and us along with it. We are not separa...

 Computer Programming Brings Complex Thought to the Masses

Omni: Does that limit the number of people who can contribute, or even understand what's being done? Feynman: Or else somebody will develop a way of thinking about the problems so that we can understand them more easily. Maybe they'll just teach it earlier and earlier. You know, it's not true that what is called "abstruse" math is so difficult. Take something like computer programming, and the careful logic needed for that--the kind of thinking that mama and papa would have said was only for ...

 The Perspectives Game

I got a kick, when I was a boy, [out] of my father telling me things, so I tried to tell my son things that were interesting about the world. When he was very small we used to rock him to bed, you know, and tell him stories, and I'd make up a story about little people that were about so high [who] would walk along and they would go on picnics and so on and they lived in the ventilator; and they'd go through these woods which had great big long tall blue things like trees, but without leaves a...

 Science is Patient Observation

I think it is very important--at least it was to me--that if you are going to teach people to make observations, you should show that something wonderful can come from them. I learned then what science was about. It was patience. If you looked, and you watched, and you paid attention, you got a great reward from it (although possible not every time). As a result, when I became a more mature man, I would painstakingly, hour after hour, for years, work on problems--sometimes many years, sometim...
