There is an abstract "thinking", just as there is abstract "feeling", "sensation" and "intuition". Abstract thinking singles out the rational, logical qualities ... Abstract feeling does the same with ... its feeling-values. ... I put abstract feelings on the same level as abstract thoughts. ... Abstract sensation would be aesthetic as opposed to sensuous "sensation" and abstract intuition would be symbolic as opposed to fantastic "intuition". (Jung, [1921] (1971):par. 678).
