If some facts 'logically supervene' on some others, they just redescribe them, adding nothing [Lynch/Glasgow]
|
|
Full Idea:
Logical supervenience, restricted to individuals, seems to imply strong reduction. It is said that where the B-facts logically supervene on the A-facts, the B-facts simply re-describe what the A-facts describe, and the B-facts come along 'for free'.

From:
Lynch,MP/Glasgow,JM (The Impossibility of Superdupervenience [2003], C)
|
|
A reaction:
This seems to be taking 'logically' to mean 'analytically'. Presumably an entailment is logically supervenient on its premisses, and may therefore be very revealing, even if some people think such things are analytic.

A notebook counts as memory, if is available to consciousness and guides our actions [Clark/Chalmers]
|
|
Full Idea:
Beliefs are partly constituted by features of the environment. ....a notebook plays for one person the same role that memory plays for another. ...The information is reliably there, available to consciousness, and to guide action, just as belief is.
|
|
From:
A Clark / D Chalmers (The Extended Mind [1998], §4)
|
|
A reaction:
This is the modern externalist approach to beliefs (along with broad content and external cognition systems). Not quite what we used to mean by beliefs, but we'll get used to it. I believe Plato wrote what it said in his books. Is memory just a role?

Facts should be deducible from the theory and initial conditions, and prefer the simpler theory [Osiander, by Harré/Madden]
|
|
Full Idea:
The two positivist criteria for a scientific theory are that the facts must be deducible from the theory together with initial conditions, and if there is more than one theory the simplest must be chosen.
|
|
From:
report of Andreas Osiander (Preface to 'De Revolutionibus' [1543]) by Harré,R./Madden,E.H. - Causal Powers 7.I
|
|
A reaction:
Harré and Madden cite this as a famous early statement of positivism. It seems to combine Hempel and Lewis very concisely. Wrong, of course. It does not, though, appear to mention 'laws'.

If something in the world could equally have been a mental process, it is part of our cognition [Clark/Chalmers]
|
|
Full Idea:
If, as we confront some task, a part of the world functions as a process which, were it done in the head, we would have no hesitation in recognising as part of the cognitive process, then that part of the world is part of the cognitive process.
|
|
From:
A Clark / D Chalmers (The Extended Mind [1998], §2)
|
|
A reaction:
In some sense they are obviously right that our cognitive activities spill out into books, calculators, record-keeping. It seems more like an invitation to shift the meaning of the word 'mind', than a proof that we have got it wrong.

Consciousness may not extend beyond the head, but cognition need not be conscious [Clark/Chalmers]
|
|
Full Idea:
Many identify the cognitive with the conscious, and it seems far from plausible that consciousness extends outside the head in these cases. But not every cognitive process, at least on standard usage, is a conscious process.
|
|
From:
A Clark / D Chalmers (The Extended Mind [1998], §3)
|
|
A reaction:
This gives you two sorts of externalism about mind to consider. No, three, if you say there is extended conceptual content, then extended cognition processes, then extended consciousness. Depends what you mean by 'consciousness'.
