Evaluate primary possibility from some world, and secondary possibility from this world [Chalmers, by Vaidya]
|
|
Full Idea:
For Chalmers, that water is XYZ is 'primary possible' (a priori, or conceptually), because it is true in some world considered as actual. It is 'secondary impossible', when it is evaluated from the Earth as actual.

From:
report of David J.Chalmers (Does Conceivability Entail Possibility? [2002]) by Anand Vaidya - Understanding and Essence Intro
|
|
A reaction:
[compressed] This is Chalmers' account of how we can know possibility from conceivability, via his two-dimensional semantics (see alphabetical themes).

We imagine small and large objects scaled to the same size, suggesting a fixed capacity for imagination [Lavers]
|
|
Full Idea:
If we think of a pea, and then of the Eiffel Tower, they seem to occupy the same space in our consciousness, suggesting that we scale our images to fit the available hardware, just as computer imagery is limited by the screen and memory available.

Michael Lavers (talk [2003]), quoted by PG - Db (ideas)

A reaction:
Nice point. It is especially good because it reinforces a physicalist view of the mind from introspection, where most other evidence is external observation of brains (as Nietzsche reinforces determinism by introspection).
