Consciousness Metzinger II 458
Consciousness/Block: is a mixed concept of "phenomenal consciousness" (P consciousness/terminology) and "access consciousness" (Z consciousness).
Def Z Consciousness/Terminology/Block: Being aware of a fact z means that the information for rational inferring is available. (Functional concept)
Consciousness/Burge: (VsBlock): P consciousness Prerequisite for Z Consciousness.
Phenomenality is not the same as consciousness! Phenomenal states can also be unconscious.
II 524
Blindsight/Block: Patients who cannot see in part of their visual field can still give true verbal descriptions upon request.
      This suggests that consciousness must have a function that is effective in survival, reporting, and behavioral control.
II 530
Access Awareness/Block: I call its basis the information-processing function of the phenomenal consciousness in >Schacter's model. (s) part or basis as a counterpart).
II 531
Def P Consciousness/Phenomenal Consciousness/Block: experience. It cannot be described non-circularly! But that's no shortcoming!
P-conscious properties are distinguished from any cognitive, intentional, or functional property. Although functionalism is wrong with respect to P consciousness, functionalism can accept many of my points.
II 535
Def Z Consciousness/Access Consciousness/Block: a state is z conscious if by virtue of being in the state a representation of its content
1) is inferentially unbound, i.e. is available as a premise for considering
2) is available for rational control of actions
3) is available for rational language control (not necessary, even chimpanzees can be p conscious).
      P consciousness and Z consciousness interact: Background can become foreground. E.g. feeling the shirt feels at the neck.
Fallacy/Block: it is a mistake, however, to go unnoticed from one consciousness to the other.
Mistake: To conclude from the example blindsight that it is the function of the P consciousness to enable rational control of action.
P Consciousness/Block: not functional! Sensations.
Z Consciousness/Block: functional. Typical: "propositional attitudes".
Pain/Block: its representational content is too primitive to play a role in inferring. Pain is not conceptually mediated, after all, dogs can also feel pain.
Summary: P Consciousness can be consciousness of and consciousness of does not need to be Z consciousness.
II 555
Consciousness/Dennett:
1) Cultural construct!
2) You cannot have consciousness without having the concept of consciousness.
3) Consciousness is a "cerebral celebrity": only those contents are conscious that are persistent, that monopolize the resources long enough to achieve certain typical and "symptomatic" effects.
BlockVsDennett:
Ad 1) this is a merging of several concepts of consciousness.
2) Consciousness cannot be a cultural product.
Also probably not the Z consciousness: many lower creatures have it, even without such a concept.
Ad 3) But that is a biological fact and not a cultural one.
II 568
Fallacy/BlockVsSearle: Question: why the thirsty blindsight patient in the example does not reach for the water: he lacks both P consciousness and Z consciousness. That's right.
But it is a mistake to go from a function of the machinery of Z consciousness to any function of P consciousness.
     Fallacy: to prematurely draw the conclusion that P consciousness has a certain function from the premise that "consciousness" is missing (without being clear what kind of consciousness).
