“We should begin thinking of events as the primary realities and of time as an abstraction from them—a concept derived mainly from regular repeating events, such as the ticking of clocks. Events are perceived, but time is not (Gibson, 1975).”

“If you add up all the wars, genocides, and terrorist acts that occurred since 1973, the death toll is a staggering twelve million. Prior to its eradication, smallpox killed 1.5 to 3 million people every year, so by preventing these deaths for over forty years, its eradication has effectively saved somewhere between 60 and 120 million lives. The eradication of smallpox is one success story from aid, saving five times as many lives as world peace would have done.”

“But, actually, an affordance is neither an objective property nor a subjective property; or it is both if you like. An affordance cuts across the dichotomy of subjective-objective and helps us to understand its inadequacy. It is equally a fact of the environment and a fact of behavior. It is both physical and psychical, yet neither. An affordance points both ways, to the environment and to the observer.”

“I believe consciousness is simply what it feels like to have a neocortex.”
