Transgressing according to Georges Bataille:
"We are discontinuous beings, individuals who perish in isolation [...] but we yearn for our lost continuity. We find the state of affairs that binds us to our random and ephemeral individuality hard to bear. Along with the tormenting desire that this evanescent thing should last, there stands our obsession with the primal continuity linking us with everything there is."
The ways, in which we move towards the limits of discontinuity into a state close to continuity, Bataille calls transgression.

I look at the skin as a limit, a boundary: a threshold between our isolated discontinuous being and the primal continuity. The skin on the border between life and death, beauty and repulsiveness, private and public, hiding and displaying, inside and outside... How does the skin border function, and what is its place? One way to find out is by the act of transgressing the skin, pushing the limits of our discontinuous Self; through the skin border.

In ecology I also stumble across the term 'transgressing'. Here it means: the sea (or river) transgressing into the land (like a flood?). In Dutch the areas where this phenomenon takes place are called a 'slufter' (a sort of Mangrove). By the act of the water transgressing into land it leaves residues, which can be 'read' as 'data' about the transgression. Could there also be residues left in or around our skin when we transgress it? The slufter is a marginal-, fringe- or peripheral area, with its own 'laws' and 'culture'. Could studying the slufter provide a perspective on transgressing the skin border?
