No: computers can't be conscious [6]

Machines can't have subjective experiences. Machines can't consciously perceive, feel, or remember anything. And, because consciousness is necessary for thought, machines can't think either.

Robert Horn Map 6: Do Computers Have to be Conscious to Think?
A full-sized version of the original can be ordered here.

The questions explored on Map 6 – Do computers have to be conscious to think? are:

  • Can computers be conscious?
  • Is consciousness necessary for thought?
  • Is the consciousness requirement solipsistic?
  • Can higher-order representations produce consciousness?
  • Can functional states generate consciousness?
  • Does physicalism show that computers can be conscious?
  • Does the connection principle show that consciousness is necessary for thought?

Note: The relation between consciousness, thinking and mentality is itself a subject of debate, some of which is represented in the argumentation around this position.
