The argument given above shows that the method of trial and error holds a much more fundamental place in the methods of adaptation. The argument shows, in fact, that when the organism has to adapt (to get its essential variables within physiological limits) by working through an environment that is of the nature of a Black Box, then the process of trial and error is necessary, for only such a process can elicit the required information. The process of trial and error can thus be viewed from two very different points of view. On the one hand it can be regarded as simply an attempt at success; so that when it fails we give zero marks for success. From this point of view it is merely a second- rate way of getting to success. There is, however, the other point of view that gives it an altogether higher status, for the process may be playing the invaluable part of gathering information, information that is absolutely necessary if adaptation is to be successfully achieved. It is for this reason that the process must enter into the kitten's adaptation. 7/5. As the kitten proceeds by trial and error, its final behaviour will depend on the outcome of the trials, on how the essential variables have been affected. This is equivalent to saying that the essential variables are to have an effect on which behaviour the kitten will produce; and this is * Env • equivalent, to saying that in the diagram of immediate effects there must be a channel from the essential variables to the parameters S; so it will resemble Figure 7/5/1. The organism that can adapt thus has a motor output to the environment and two feedback loops. The first loop was shown in Figure 7/2/1; it consists of the ordinary sensory input from eye, ear, joi
