Top Down Bottom Up

“In the designs I have been involved in, and which have not involved too many people, I have not been able to identify whether these have been ‘top-down’ or ‘bottom-up’. They seem to me to be more like frame stressing,”

Strange Consciousness

“My belief is that the explanations of emergent phenomena in our brains — for instance, ideas, hopes, images, analogies, and finally consciousness and free will — are based on a kind of Strange Loop, an interaction between levels in which the top loop reaches back down towards the bottom level and influences it, while at the same time being itself determined by the bottom level. In other words, a self-reinforcing resonance between different levels.”

Top and Bottom

“Talking about where one starts is, I think, perhaps a slight lie. One starts in fact with the grand conception, including the top and the bottom.”

It From Bit

“It from bit symbolizes the idea that every item of the physical world has at bottom — at a very deep bottom, in most instances — an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes-no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe.”
