This paper is a reflexion about the relation of our society to the edges and limits and the general tendance to transgression. We introduce a division between the "hard" and the "soft" pole into the contemporary approach of limits.
These poles correspond to two categories of valors, but within of either of them extremities are researched. In despite of their opposition the two poles are equally narcissic.
In opposition to them, we situate three kinds of experience given to us by psychotherapy, art and the play/game because all invite humans to reflect their relation to limits for redefining them.
