| Abstract: | From a paean of praise to the innovator : When you first brought these trees and told us we should grow them, we scoffed at you and said ‘We have plenty of trees already; what use are these new ones?’ But now we see we were wrong: money grows on those trees. On the indivisibility of systems : No one part of the model-system is more important than any other part. We may consider each model as a vital link in a communications system. We may identify feedback effects. Every change in technology or change in aspiration levels will lead to a re-appraisal of the environment. Every movement of knowledge over space will need to be checked against environment and environment itself will change as a result of the decisions made. Changes in social structure may lead to changes in organizational behaviour and so on. |
