Imagine God behind a screen and us in front of it. Kant says we have invented the screen upon which we project the world. God is unknowable behind it. Heidegger says God made the screen, but in an odd twist he says the screen projects or creates us.God is equally hidden behind the screen.
These are the antecedents of contemporary philosophy, and its introspection and irrelevant God. I am still struggling with its impact on the visual arts, but starting with Foucault.
Critique of Foucault is like attacking a fog. Armed and alarmed, I wield simile and metaphor extended, spinning and kicking, hoping a knife will pierce the heart of the fog.
