• Psychiatric syndromes are defined psychologically. Why then has Holzman written that psychiatry maintains a wall between itself and psychology? Why does the Archives publish so few articles on psychological topics? And why does psychiatry neglect psychology in other ways? Holzman has suggested that chauvinism is at fault, but for Archives this is not the case. It seems more likely that the problem reflects difficulties with our understanding of the nature of teleonomic explanations.
