My Psychosis, My Bicycle, and I

The following is a passage from:

My plan is to chew up this passage and have it spat out
by one of the characters in "Mad Schoolhouse,"
but I don't know which character should spout it, yet.

You see, I can't decide if this passage sounds too insane
to be spoken by the main character,
in which case it should be spoken by one of his
prisoners, i.e.-someone more insane than the main character.

"Should one wish to bring the Cartesian model of cognition and world view together, it must first be ascertained that Descartes starts from a world that is as it is. It has been created by God in the same way that a machine is constructed and assembled by an engineer. Its parts are separate things whose characteristics cannot be traced back to each other. This machine runs, but its mechanisms are static and unchangeable. The correlation of these objects, which by nature exist independent from each other, is determined by mechanical laws. Cause and effect are combined in such a way that the cause determines the effect. The mind striving for cognition stands opposite this machine. In principle its observations have no effect on the material processes being observed. The rules of mechanics in the outside world correspond to the rules of reason inside. The truth can only be found by following these rules. Cognition is, when successful, a reproduction of reality. The aim is to make this clockwork world calculable and predictable."

Fritz B. Simon.

What do you think?

Is it too insane for a main character to say? What about to think?
