Firstly, by analysing its biological function, I show
that there is a best possible form of cognition, which gives
greatest fitness. The results of this optimal cognition can be
calculated in any domain -- such as foraging, navigation, vision,
or conditioning. Secondly, internal representations and symbols
emerge as a feature of near-optimal cognition. This gives a
biological basis for cognitivism. Finally, we do not expect brains
to evolve to the precise optimum. However, there are indications
that animal cognition usually comes close to optimum efficiency,
while today's cognitive models (such as neural nets or
reinforcement learning models) have a wide range of efficiencies.
