Machines (Humanly Constructed Artifacts) Cannot Think
Machines (humanly constructed artifacts) cannot think because no machine has a point of view; that is, a unique perspective on the worldly referents of its internal symbolic logic. We, as conscious cognitive observers, look at the output of so-called "thinking machines" and provide our own referents to the symbolic structures spouted by the machine. Of course, despite this limitation, such non-thinking machines have provided an extremely important adjunct to human thought.
