"Invisible bodies, no doubt by definition, can be done away with much more easily than visible ones. Since...ghosts...and the like take up no physical space in our empirical world, the liquidation of them involves no bloodletting, leaves no corpses and calls for no official inquiry." (William La Fleur in Gordon, 1997, p.143)

It is as easy to deny the existence of ghosts as it is to assert it. But, as Derrida asks, what is a ghost? Stephen Dedalus argues that a ghost is one who has faded into impalpability - their presence is made manifest through an absence of touch. It is their signature.

On this estimation, then, we live in a world riddled with ghosts. Every exchange stripped of tactility is an instance of a spectral encounter.

Ghosts are neither here nor there. And neither are we.
