ABSTRACT

The subject o f the Cartesian cogito does not think, he has only the possibility o f thinking, and remains stupid at the heart o f this possibility.

(Deleuze, 1968, 354)

It is impossible to blow open the top of a man’s head, says the judge in R v Moloney ([ 1985] 1 All E R 1025), a case about a man who blows open the top of a man’s head, — to unshell it, as it were, so as to examine his thinking like an oyster, or a watch-spring, or a nut.
