This breezy, superficial sketch of mental architecture is the kind of facile generalization with little or no referent that gives psychobabble a bad name. Fear is not the common denominator of all unpleasant emotions anymore than courage is the common denominator of all the more positive ones. Or it may be, if you are using some new meaning for the word, not disclosed in your authoritative revelation. Emotion is a rich blend of cognitive factors, physical states and degrees of affinity (positive or negative) only some of which add up to what fear usually means. I think, therefore, that there is slipshod semantic sloppiness at play in your sage-like assertions, good Hawkster.
