I have been careful not to use either of the terms, 'emotional' or 'affective'. I have been equally careful not to invoke the notion of 'cognition'. The classic distinction which separates these two constructs has, in the manner of most classic distinctions that once were useful, become a barrier to sensitive psychological inquiry. When one so divides the experience of man, it becomes difficult to make the most of the holistic aspirations that may infuse the science of psychology with new life, and may replace the classicism now implicit even in the most 'behaviouristic' research.
