1/12 DESIGN FOR A BRAIN 



generally. We commence with the concepts that the organism 

 is mechanistic in action, that it is composed of parts, and that 

 the behaviour of the whole is the outcome of the compounded 

 actions of the parts. Organisms change their behaviour by 

 learning, and change it so that the later behaviour is better 

 adapted to their environment than the earlier. Our problem is, 

 first, to identify the nature of the change which shows as learning, 

 and secondly, to find why such changes should tend to cause 

 better adaptation for the whole organism.
