M Ted:

"The things, moreover, that do not have intelligence do not tend toward a result unless directed by some one knowing and intelligent; just as an arrow is sent by an archer. Therefore there is something intelligent by which all natural things are arranged in accordance with a plan---and this we call God."

I think that this point, which is assumed, can be argued.

Is water intelligent? Does it run downhill, as oppoesed to uphill? And where is the intelligent direction?
