Existential essentialism is not about certainty about the external world, it is expressionism of what really is as a synthetic intuition of the external and internal world. Language construct certainty about the external world. Synthetic intuition express truth of the external and internal world. Look at Edvard Munchs paiting “Autumn Ploughing” 1919. This picture unfold the human soul and the farmers work to bring forth a healthy soil after harvest. It is not a certain picture of what has happen, but an expression of Munchs synthetic intuition. Munch is not only a spectator to the farmers work. He participate in the work bringing his platonic truth into the farmers field of ploughing.
