Mountaineering with Jung

 "In order to orient ourselves, we must have a function which ascertains that something is there (sensation); a second function which establishes what it is (thinking); a third function which states whether it suits us or not, whether we wish to accept it or not (feeling); and a fourth function which indicates where it came from and where it is going (intuition)." 

 Jung, Carl. Collected works, Vol. 11, Part IV, "The Problem of the Fourth."

    Jung               Aristotle      

   Sensation ≡  Material Cause

Thinking  ≡ Formal Cause

      Feeling ≡ Efficient Cause

Intuition  ≡  Final Cause

N.B. In Peirce’s The Doctrine of Necessity Examined, he is describing how Democritus is thinking about one cause, but the pre-Socratic philosophers were thinking about three causes, pre Aristotle. He links Democritus’ understanding of efficient cause with external compulsion; without any notion of material cause: the main association (unnecessarily) with scientific determinism. This notion, analogously, of Feeling with an external compulsion seems particularly relevant to modern notions justice, which ironically Peirce indicates with his remarks on Stoicism.
