Intelligent behaviour will result from correct reasoning with correct representation
Adaptive behaviour is the product of closed-loop control
“What am I supposed to do with these things? All I know about is first-order predicate calculus!”
This is a simple demonstration of the basic mechanical, electrical, and control system working together
in the world
“Much of what we think will of course prove to be mistaken; that is one advantage of real experiments over thought experiments.”
(Dennett on the Cog project)
“How is intentionality possible? How is it that states of mind can be about the world? How are symbols grounded?”
“A clear and well-defined causal story can be told about how sentences in Ludwig’s memory come to be there. The story starts with the state of the world, moves on to how this causes electrical signals in the robot’s sensors, and concludes with computational processes that transform these into representations. The abductive account spells out exactly the sense in which the resulting representations are correct.”
“What are propositional attitiudes? What are beliefs, desires, and intentions, and what part do they play in a (functionalist) theory of mind?”
“A precise causal story can be told about how representations in Ludwig’s memory arrive there, interact with each other, and issue in robot actions. The story involves well-defined computational processes of sensor data assimilation and planning through logical inference.
(You don’t seriously think the human mind is like this do you?)”
“The natural world as we know it ... is thoroughly conditioned by [certain] features: our experience is essentially experience of a spatio-temporal world of law-governed objects conceived of as distinct from our temporally successive experiences of them” (Strawson on Kant)
“Ludwig’s background theory must contain axioms about time, action, change, space, and shape, and the hypotheses that explain sensor data are therefore constrained to be expressed in those terms.”
“But what is the nature of consciousness? How does it arise in physical matter?”
“What? Hmmm, well, let me take a step back…”
Machine consciousness and cognitive robotics: two research agendas or one?
Two agendas with a very large area of overlap
