Au-Dela des Descriptions Geometriques et Logiques de L'espace

Which is the best way of describing spatial prepositions? Even though geometry and logic provide rigorous and useful tools for this undertaking, I will show that they fall short from describing completely these prepositions. A complete description must take into consideration the movement and the function of their prepositional terms as well as cognitive notions like access to perception, potential meeting, the relationship container/ contained, etc. General orientation, a family resemblance concept whose main features are the frontal direction, the direction of movement and the line of sight, is also needed.
