The remarkable achievements that modern science has made in physics, chemistry, biology, medicine, and engineering contrast sharply with our limited knowledge of the human mind and behavior. A major reason for this slow progress, claims Gary Cziko, is that with few exceptions, behavioral and cognitive scientists continue to apply a Newtonian-inspired view of animate behavior as an organism's output determined by environmental input.
"The fish's streamlined shape reveals functional knowledge ofthe physical properties of water.... The deadly effectiveness of the cobra's venom shows useful knowledge of the physiology of its prey.... Indeed, knowledge itself may be broadly conceived as the fit of some aspect of an organism to some aspect of its environment,whether it be the fit of the butterfly's long siphon of a mouth to theflowers from which it feeds or the fit of the astrophysicist's theories to the structure of the universe.... But how did such remarkable instances of fit arise?
