Genuine motion, rather than variation of position, requires the 'entire presence' of the object [Fine,K]
|
|
Full Idea:
In order to have genuine motion, rather than mere variation in position, it is necessary that the object should be 'entirely present' at each moment of the change. Thus without entire presence, or existence, genuine motion will not be possible.

From:
Kit Fine (In Defence of Three-Dimensionalism [2006], p.6)
|
|
A reaction:
See Idea 4786 for a rival view of motion. Of course, who says we have to have Kit Fine's 'genuine' motion, if some sort of ersatz motion still gets you to work in the morning?

4-D says things are stretched in space and in time, and not entire at a time or at a location [Fine,K]
|
|
Full Idea:
Four-dimensionalists have thought that a material thing is as equally 'stretched out' in time as it is in space, and that there is no special way in which it is entirely present at a moment rather than at a position.
|
|
From:
Kit Fine (In Defence of Three-Dimensionalism [2006], p.1)
|
|
A reaction:
Compare his definition of 3-D in Idea 12295. The 4-D is contrary to our normal way of thinking. Since I don't think the future exists, I presume that if I am a 4-D object then I have to say that I don't yet exist, and I disapprove of such talk.

You can ask when the wedding was, but not (usually) when the bride was [Fine,K, by Simons]
|
|
Full Idea:
Fine says it is acceptable to ask when a wedding was and where it was, and it is acceptable to ask or state where the bride was (at a certain time), but not when she was.
|
|
From:
report of Kit Fine (In Defence of Three-Dimensionalism [2006], p.18) by Peter Simons - Modes of Extension: comment on Fine p.18
|
|
A reaction:
This is aimed at three-dimensionalists who seem to think that a bride is a prolonged event, just as a wedding is. Fine is, interestingly, invoking ordinary language. When did the wedding start and end? When was the bride's birth and death?

Three-dimensionalist can accept temporal parts, as things enduring only for an instant [Fine,K]
|
|
Full Idea:
Even if one is a three-dimensionalist, one might affirm the existence of temporal parts, on the grounds that everything merely endures for an instant.
|
|
From:
Kit Fine (In Defence of Three-Dimensionalism [2006], p.2)
|
|
A reaction:
This seems an important point, as belief in temporal parts is normally equated with four-dimensionalism (see Idea 12296). The idea is that a thing might be 'entirely present' at each instant, only to be replaced by a simulacrum.

'Contingent' means that the cause is unperceived, not that there is no cause [Hobbes]
|
|
Full Idea:
For contingent, men do not mean that which hath no cause, but that which hath not for cause any thing that we perceive, as when a traveller meets a shower, they both had sufficient causes, but they didn't cause one another, so we say it was contingent.
|
|
From:
Thomas Hobbes (Of Liberty and Necessity [1654], §95)
|
|
A reaction:
Contingent nowadays means 'might not have happened', or 'does not happen in all possible worlds'. Personally I share Hobbes' doubts about the concept of contingency, and this is quite a good account of the misunderstanding.

If a blind persons suddenly sees a kestrel, that doesn't make visual and theoretical kestrels different [Papineau on Jackson]
|
|
Full Idea:
An ornithological Mary might know everything theoretical about kestrels, but be blind from birth, then have her sight restored. She now knows "That bird eats mice", so visual kestrels must be ontologically distinct from theoretical ones.

comment on Frank Jackson (Epiphenomenal Qualia [1982]) by David Papineau - Thinking about Consciousness 6.3
|
|
A reaction:
A nice reductio, and I think this pinpoints best what is wrong with the knowledge argument. Knowledge, and the means of acquiring it, are two distinct things. When I see x, I don't acquire knowledge of x, AND knowledge of my seeing x.

Mary learns when she sees colour, so her complete physical information had missed something [Jackson]
|
|
Full Idea:
It seems obvious that Mary will learn something about the world when she is released from her black-and-white room; but then it is inescapable that her previous knowledge was incomplete; she had all the physical information, so there is more to have.
|
|
From:
Frank Jackson (Epiphenomenal Qualia [1982], §1)
|
|
A reaction:
This is Jackson's famous 'knowledge argument', which seems to me misconceived. Since I don't think phenomenal colours are properties of objects (Idea 5456), Mary learns more about herself, and about her means of acquiring knowledge.
