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.

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.

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.

Probabilistic causation says C is a cause of E if it increases the chances of E occurring [Mellor, by Tooley]
|
|
Full Idea:
The basic idea of probabilistic causation is that a sufficient condition of C's being a cause of E is that C and E are actual, individual events, and the objective chance of E's occurring is greater given the occurrence of C than it would be without C.
|
|
From:
report of D.H. Mellor (The Facts of Causation [1995]) by Michael Tooley - Causation and Supervenience 5.3
|
|
A reaction:
Mellor has to include objective 'chances' in his ontology to support his theory. As it stands this looks like a weak theory, since the event might not occur despite C happening, and some less likely event might turn out to be the actual cause.
