ABSTRACT

In 1977 Skinner complained: ‘When one has published nine books setting forth a scientific position it is disconcerting to find it misunderstood. To be misunderstood by a former student and present colleague is especially puzzling’ (p. 1006). In a similar vein I find my colleague’s comments puzzling and welcome this opportunity to ‘… try to set the record straight’ (p. 1006).
