ABSTRACT
One of the central ideas of this book is that much of what is regarded as psychopathology is not equivalent to medical notions of disease or illness. For example, are subordinate animals, who show high levels of fear and defensive arousal, ill or diseased? Does the yielding subroutine constitute an illness? Of course, much depends on the definitions of disease and illness (Kendell 1975). What we sometimes regard as pathology may represent the activation of brain states that have evolved as potential states; i.e. they are part of various psychobiological prepared options. This leads us to Hill's (1968) distinction of the differences between posture, reaction and disease.
