Transcript Roger Penrose`s Argument Against Though Compuation

Roger Penrose’s Argument
Against Though Computation
Quantum Mechanics Doesn’t Cover
It All
• Penrose believes that if recreating human
thought is even possible then laws of
physics, especially quantum mechanics
must be rewritten
• We must account for what Penrose calls
“quantum gravity”
Quantum Gravity
• Most physicists do not believe that
quantum theory needs to change when it
is united with general relativity
• They argue that on such a small scale the
effects of quantum gravity is totally
insignificant
• Penrose disagrees and feels that
Einstein’s space-time theory effects
quantum mechanics
(Penrose “Emperor’s New Mind” 348 – 349)
Penrose and His Three Worlds
• These three worlds make
up our world
• The Physical world can
be expressed in terms of
mathematics
• The Mental world
possesses our
consciousness
• The Platonic world only
encompasses a small
portion of the Physical
world
(Penrose “The Large” 97 – 98)
Strong Artificial Intelligence
• Claim that some forms of artificial intelligence
can reason and solve problems. Strong-AI
states that it is possible for machines to become
self-aware, however they may or may-not exhibit
human-like thought processes.
• John Searle shares this belief. He uses his
Chinese room example to discredit this through
the failure to discredit the Turing Test
(Searle “Minds, Brains”)
Penrose and Searle
• Penrose and Searle agree that the Chinese room give a
convincing case against the Strong AI position that
computation alone can even suggest conscious
mentality
• However Penrose believes that the Chinese room
argument is entirely negative and does not provide us
with any real clue as to what is actually going on with
consciousness nor does it indicate any direction in which
we should proceed if we are to attempt to move towards
a scientific basis for mentality
(Penrose “The Large” 173 – 174)
