Rappard has written a stimulating chapter raising so many issues that a commentary doing justice to all of them would have to be as long as the chapter itself. Unfortunately, I do not have an overall account of the implications of the history of psychology for theoretical psychology that I could offer as an alternative to Rappard's viewpoint. I have, therefore, decided to focus on three separate issues that do not bear any obvious systematic relationship to each other, except that they all came to my mind while reading Rappard's essay.
