High Quality Content by WIKIPEDIA articles! Evolutionary Logic is the idea that logical rules can be reduced to biology. It is a theory of rationality in which rational and logical rules emerged for pragmatic reasons, and are therefore not special laws. The formal systems of logic have ordinarily been studied independently, but (continual) progress in evolutionary theory suggests that biology and logic could be intimately interrelated. Evolutionary Logic suggests that the principles of reasoning are neither fixed, absolute, independent, nor elemental. Instead it is the evolutionary dynamic that is elemental.
