Let us compare painting and science…… "The scientist observes the world as if from outside or above, he or she 'manipulates things and gives up living in (or with) them', By focusing on abstract objects that can be known by a transcendental observer, science loses touch with the real world in which our lives unfold.
Alternately, science sometimes unfolds (as in cybernetics) as an absolute mechanism or artificialism, turning any successful technique in one region loose on others, without ever asking why the technique works here, but not there. This operational thinking is a genuine threat to humanity—since human nature is existentially created, science threatens to turn us in to 'human machines' by destroying the expressive Being-in-the-world and essentially inter-corporeal being that we are.
The only protection is to identify and refuse the pensee de survol by returning to the 'there is' of the concrete world as the place of our lives. A genuine philosophy (metaphysics) must begin with the phenomenololgical world of the things themselves, and not the scientific world of the things in general.
Art, and 'especially painting', begins from precisely this 'fabric of brute (primeval) meaning', that is the lived world. The painter is charged with no other task than to capture the appearing of things themselves, taking up the world through and from the visible, and this, Merleau-Ponty suggests, is the 'fundamental of all painting, perhaps of all culture.'"
