If you know your father, but don't recognise your father veiled, you know and don't know the same person [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'undetected' or 'veiled' paradox of Eubulides says: if you know your father, and don't know the veiled person before you, but that person is your father, you both know and don't know the same person.

|
From:
report of Eubulides (fragments/reports [c.390 BCE]) by R.M. Dancy - Megarian School
|
|
A reaction:
Essentially an uninteresting equivocation on two senses of "know", but this paradox comes into its own when we try to give an account of how linguistic reference works. Frege's distinction of sense and reference tried to sort it out (Idea 4976).

Removing one grain doesn't destroy a heap, so a heap can't be destroyed [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'sorites' paradox of Eubulides says: if you take one grain of sand from a heap (soros), what is left is still a heap; so no matter how many grains of sand you take one by one, the result is always a heap.

From:
report of Eubulides (fragments/reports [c.390 BCE]) by R.M. Dancy - Megarian School
|
|
A reaction:
(also Cic. Acad. 2.49) This is a very nice paradox, which goes to the heart of our bewilderment when we try to fully understand reality. It homes in on problems of identity, as best exemplified in the Ship of Theseus (Ideas 1212 + 1213).

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?

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'.
