Artificial Intelligence Chalmers I 185
Artificial Intelligence/Chalmers: Suppose we had an artificial system that rationally reflects what it perceives. Would this system have a concept of consciousness? It would certainly have a concept of the self, it could differ from the rest of the world, and have a more direct access to its own cognitive contents than to that of others. So it would have a certain kind of self-awareness. This system will not say about itself, that it would have no idea how it is to see a red triangle. Nor does it need access to its elements on a deeper level (Hofstadter 1979 1, Winograd 1972 2). N.B.: such a system would have a similar attitude to its inner life as we do to ours.
Cf. >Artificial consciousness, >Self-consciousness, >Self-knowledge,
>Self-identification, >Knowing how.
I 186
Behavioral explanation/Chalmers: to explain the behavior of such systems, we never need to attribute consciousness. Perhaps such systems have consciousness, or not, but the explanation of their behavior is independent of this. >Behavior, >Explanation.
I 313
Artificial Intelligence/VsArtificial Intelligence/Chalmers: DreyfusVsArtificial Intelligence: (Dreyfus 1972 7): Machines cannot achieve the flexible and creative behavior of humans. LucasVsArtificial Intelligence/PenroseVsArtificial Intelligence/Chalmers: (Lucas 1961 3, Penrose, 1989 4): Computers can never reach the mathematical understanding of humans because they are limited by Goedel's Theorem in a way in which humans are not. Chalmers: these are external objections. The internal objections are more interesting:
VsArtificial intelligence: internal argument: conscious machines cannot develop a mind.
>Mind/Chalmers.
SearleVsArtificial Intelligence: > Chinese Room Argument. (Searle 1980 5). According to that, a computer is at best a simulation of consciousness, a zombie.
>Chinese Room, >Zombies, >Intentionality/Searle.
Artificial Intelligence/ChalmersVsSearle/ChalmersVsPenrose/ChalmersVsDreyfus: it is not obvious that certain physical structures in the computer lead to consciousness, the same applies to the structures in the brain.
>Consciousness/Chalmers.
I 314
Definition Strong Artificial Intelligence/Searle/Chalmers: Thesis: There is a non-empty class of computations so that the implementation of each operation from this class is sufficient for a mind and especially for conscious experiences. This is only true with natural necessity, because it is logically possible that any compuation can do without consciousness, but this also applies to brains. >Strong Artificial Intelligence.
I 315
Implementation/Chalmers: this term is needed as a bridge for the connection between abstract computations and concrete physical systems in the world. We also sometimes say that our brain implements calculations. Cf. >Thinking/World, >World, >Reality, >Computation, >Computer Model.
Implementation/Searle: (Searle 1990b 6): Thesis is an observational-relativistic term. If you want, you can consider every system as implementing, for example: a wall.
ChalmersVsSearle: one has to specify the implementation, then this problem is avoided.
I 318
For example, a combinatorial state machine has quite different implementation conditions than a finite state machine. The causal interaction between the elements is differently fine-grained. >Fine-grained/coarse-grained.
In addition, combinatorial automats can reflect various other automats, like...
I 319
...Turing-machines and cellular automats, as opposed to finite or infinite state automats. >Turing-machine, >Vending machine/Dennett.
ChalmersVsSearle: each system implements one or the other computation. Only not every type (e.g., a combinational state machine) is implemented by each system. Observational relativity remains, but it does not threaten the possibility of artificial intelligence.
I 320
This does not say much about the nature of the causal relations. >Observation, >Observer relativity.

Behavior Peacocke I 51
Perception/behavior explanation/behavior/Peacocke: Our perceptions are always much finer than the possibly resulting actions. >Overdetermination, >Indeterminacy, >Behavioral explanation,

Epistemic/ontologic Field II 102
Behavioral explanation/real possibility/epistemic/Stalnaker: behavior must be explained in terms of genuine (non-epistemic) possibility. Intelligent behavior/Stalnaker: may only be explained in terms of possibilities that represent these possibilities.
Field: without using the concept of "meaning".
>Meaning.
II 105
Epistemic/Field: E.g. epistemic term of truth conditions: "is verified in the long term". FieldVs: this is not a good definition of truth conditions. With this, truth is defined in terms of verification.
>Truth conditions, >Verification.
II 286
Epistemic Theory/Vagueness/Field: Epistemic Theory: accepts facts. >Facts.
Non-epistemic theory: can assert that it is conceptually impossible in certain cases that we can decide. - For example, if something is a borderline case of a property. >Vagueness, >Sorites.

Explanation Peacocke I 71
Explanation/behavior/Peacocke: assuming, the spatial relations of a subject determine its settings. Problem: then we could explain the behavior solely from the accepted beliefs of the subject without mentioning the spatial relations.
>Belief attitudes, >Spatial localization, >Behavior, >Behavioral explanation.
I 81
Narrow explanation/Peacocke: E.g. someone has only the terms "there is an F", "there are two Fs", "There are three Fs" and "the Fs are numerically equivalent to the Gs". Then operations with higher numbers are explainable with these few terms.
>Numerical equality.
E.g. He actually arranges 20 pebbles and pieces of gold one to one.
Then there is no difference in his intentional actions without one which is formulated with its few terms.
>Intentions.
Problem: such an unstructured ability would then be necessary and a priori. "Numerically equivalent"/numerical equality: can be treated as an unstructured operator of 2nd order.
>Operators, >Description levels, >Levels/order, >Second Order Logic.
I 133ff
Explanation/Peacocke/Nozick: must rely on the nature of the object, not on the manner of givenness. - ((s) intension: is virtually equated with appearance- "nature" with "real object".) >Way of givenness, >Intensions.
I 185
Action explanation/Peacocke: by properties of objects - explanation of thoughts: by specific markings - better: by the object itself. ---
I 192
Action explanation/Peacocke: in the case of properties no specific object is meant: E.g. "red lamp", not "John's favorite color" - demonstrative: specific object, descriptively: can also be another object.
