Contemporary research concerning the cognitive links between perception, language, and action — see for instance Talmy's works — have revolutionized the dominating traditions of formal semantics. They have led to what Husserl already called in Erfahrung and Urteil a genealogy of logic, a perceptive genealogy of cognitive symbolic structures. Such a Gestalt-like perspective on symbolic structures raises a lot of new problems. It makes traditional simple — and even trivial — problems appear as complex, non trivial, ones.
