Evolutionary game theory is a way of thinking about evolution at the phenotypic level when the fitnesses of particular phenotypes depend on their frequencies in the population.

Societies depend on agreed rules.

Scientific theories tell us what is possible; myths tell us what is desirable. Both are needed to guide proper action.

Language changes very fast.

So far, we have been able to study only one evolving system and we cannot wait for interstellar flight to provide us with a second. If we want to discover generalizations about evolving systems, we will have to look at artificial ones.

Mathematics without natural history is sterile, but natural history without mathematics is muddled.
