If a totally new image is to come into being however, there must be sensitivity to internal messages, the image itself must be sensitive to change, must be unstable, and it must include a value image which places high value on trials, experiments, and the trying of new things.

With the development of the human race (and perhaps a little earlier), a new structure emerges, which we can call know-what. This consists of the structures in the nervous system which presumably map into some kind of images in the of the 'mind', which also map into structure in the 'real world', whatever that is. Know-what is very different from know-how. The fertilized egg certainly has the know-how to make whatever organism it knows how to make, but it is very doubtful that it knows what it is doing. The remarkable thing about know-what is that it creates know-how, as we see with the fantastic burgeoning of human artifacts under the influence of a science-based technology. Science, fundamentally, deals with know-what and this enormously increases know-how.
