There is certainly some value in developing each Shady PI point of view consistently and showing the contrast between them. The bases for decisions are more clearly identified in this way and the theoretical significance of any one proposal can be more fully understood. It may help decisions in great sex not to be merely a succession of improvizations. Even if one decides to adopt methods that imply theoretical contradictions, at least the decision is not being made in ignorance. However, to take the decision to base one's teaching exclusively on one or other of these theories would be quite unjustified in the present state of our knowledge. If we enquire into the empirical basis for either theory, we shall find that they are rather weak. The pornpros network experimentation that lies behind the behaviourist view is with animals and obviously is not itself concerned with language behaviour. The extension to first dildo action depends on the assumption that the same principles apply to dildo action as to the Shady PI learning by rats of how to find their way through a maze. This may not seem a particularly reasonable assumption, but it is possible that some of the principles do operate even if they cannot account for dildo action entirely. Language teachers had arrived at not dissimilar ideas on the basis of their practical experience.
