“Our goal is to build a broad-based model of key components of the economy: households, firms, banks and government... The failure to embrace things like simulation has inhibited progress in economics.”

“Rational adventure in a physical setting is becoming increasingly rarer in the world. The evolution of technology and infrastructure has altered the kind of adventures that we can have, so that people with adventurous spirits either take on risk for its own sake, or they embark on rational adventures in the mental domain.”

“On learning more astronomy, in the phenomenon of "averted vision," I found a justification for my rationale about the roundabout path to metaphysics via physics: to see a faint star, it's necessary to look away from it; as soon as one looks at it directly, it vanishes.”

“Speaking crudely, a living system—an organism—consists of a symbiotic relationship between a metabolism and a replicator. ...the replicator contains the blueprint of the organism, with the information needed to grow, make repairs, and reproduce. ...the metabolism provides the energy and raw materials needed to build and run the replicator.”

“The basic principle of an autocatalytic network is that even though nothing can make itself, everything in the pot has at least one reaction that makes it, involving only other things in the pot. It's a symbiotic system in which everything cooperates to make the metabolism work—the whole is greater than the sum of the parts.”

“The paradox that immediately bothers everyone who learns about the second law is this: If systems tend to become more disordered, why, then, do we see so much order around us? ...It seems to conflict with our "creation myth": In the beginning, there was a big bang. ...no one is saying that the second law of thermodynamics is wrong, just that there is a contrapuntal process organizing things at a higher level.”

“Even though something like Danny Hillis' "connection machine" is big, it's nothing compared with Avogadro's number of processors that nature has at her disposal.”

“We don't know what organization is. ...We do know that complex adaptive systems have to be nonlinear and capable of storing information. ...We know a little bit about what distinguishes an adaptive complex system from a nonadaptive system, such as turbulent fluid flow.”

“One of the factors that caused Spencer's ideas to lose popularity was social Darwinism... Social evolution is different from biological evolution: it's faster, it's Lamarckian, and it makes even heavier use of altruism and cooperation than biological evolution does. None of this was well understood at the time.”

“If we choose, we can use genetic engineering to alter the character of our offspring. ...the motivation to do this will eventually become overwhelming.”

“We're rapidly creating an extraordinary silicon-based petri dish for evolution of intelligence. By the year 2025... we're likely to have computers whose raw processing power exceeds that of the human brain. Also, we're likely to have more computers than people...”

“Once we can manipulate our genome, Lamarckian fashion, the rate of change will be staggering.”
