[explaining happenings in terms of another mode of existence]

19 ideas
Events are just interpretations of groups of appearances [Nietzsche]
     Full Idea: There is no event in itself. What happens is a group of appearances selected and summarised by an interpreting being.
     From: Friedrich Nietzsche (Unpublished Notebooks 1885-86 [1886], 1[115])
     A reaction: Since innumerable events are nested within one another, such as the events at a carnival, this is obviously true. A primitive 'Kim event' (an object changes a property) might have objective existence. Carnivals happen, though.
Explaining events just by bodies can't explain two events identical in space-time [Quine]
     Full Idea: An account of events just in terms of physical bodies does not distinguish between events that happen to take up just the same portion of space-time. A man's whistling and walking would be identified with the same temporal segment of the man.
     From: Willard Quine (On Multiplying Entities [1974], p.260)
     A reaction: We wouldn't want to make his 'walking' and his 'strolling' two events. Whistling and walking are different because different objects are involved (lips and legs). Hence a man is not (ontologically) a single object.
A physical event is any change of distribution of energy [Ellis]
     Full Idea: We may define a physical event as any change of distribution of energy in any of its forms.
     From: Brian Ellis (The Metaphysics of Scientific Realism [2009], 2)
     A reaction: This seems to result in an awful lot of events. My own (new this morning) definition is: 'An event is a process which can be individuated in time'. Now you just have to work out what a 'process' is, but that's easier than understanding an 'event'.
Events are fast changes which are of interest to us [O'Connor]
     Full Idea: The standard cases of events are physical changes which happen sufficiently fast to be observed as changes, and which are of sufficient interest to us to be noticed or commented on.
     From: D.J. O'Connor (The Correspondence Theory of Truth [1975], Ch.7)
Events are made of other things, and are not fundamental to ontology [Bennett]
     Full Idea: Events are not basic items in the universe; they should not be included in any fundamental ontology...all the truths about them are entailed by and explained and made true by truths that do not involve the event concept.
     From: Jonathan Bennett (Events and Their Names [1988], p.12), quoted by Peter Simons - Events 3.1
     A reaction: Given the variable time spans of events, their ability to coincide, their ability to contain no motion, their blatantly conventional component, and their recalcitrance to individuation, I say Bennett is right.
The claim that events are individuated by their causal relations to other events is circular [Lowe on Davidson]
     Full Idea: Davidson has urged that events are individuated by the causal relations which they bear to one another, in accordance with the principle that events are identical just in case they have the same causes and effects. But the principle is viciously circular.
     From: comment on Donald Davidson (The Individuation of Events [1969]) by E.J. Lowe - The Possibility of Metaphysics 7.4
     A reaction: You wouldn't want to identify a person just by their relationships, even though those will certainly be unique. Generally it is what I am (right now) naming as the Functional Fallacy: believing that specifying the function of x explains x.
How fine-grained Kim's events are depends on how finely properties are individuated [Kim, by Schaffer,J]
     Full Idea: How fine-grained Kim's events are depends on how finely properties are individuated.
     From: report of Jaegwon Kim (Events as property exemplifications [1976]) by Jonathan Schaffer - The Metaphysics of Causation 1.2
     A reaction: I don't actually buy the idea that an event could just be an 'exemplification'. Change seems to be required, and processes, or something like them, must be mentioned. Degrees of fine-graining sound good, though, for processes too.
Events are composed of an object with an attribute at a time [Kim, by Simons]
     Full Idea: Kim's events are exemplifications by an object of an attribute at a time...It does not make events basic entities, as the three constituents are more basic, but it gives identity conditions (two events are the same if object, attribute and time the same).
     From: report of Jaegwon Kim (Events as property exemplifications [1976]) by Peter Simons - Events 2.1
     A reaction: [Aristotle is said to be behind this] I am more sympathetic to this view than the claim that events are primitive. If a pebble is ellipsoid for a million years, is that an event? I think the concept of a 'process' is the most fruitful one to investigate.
Events cannot be merely ordered triples, but must specify the link between the elements [Kim, by Simons]
     Full Idea: Kim's events cannot just be the ordered triple of , since many such triples do not yield events, such as . Kim has to specify that the object actually has that property at that time.
     From: report of Jaegwon Kim (Events as property exemplifications [1976]) by Peter Simons - Events 2.1
     A reaction: Why should they even be in that particular order? This requirement rather messes up Kim's plan for a very streamlined, Ockhamised ontology. Circles have symmetry at all times. Is 'near Trafalgar Square' a property?
If events are ordered triples of items, such things seem to be sets, and hence abstract [Simons on Kim]
     Full Idea: If Kim's events are just the ordered triple of is that such things are standardly conceived as abstract entities, usually sets, whereas events are concretely located in space and time.
     From: comment on Jaegwon Kim (Events as property exemplifications [1976]) by Peter Simons - Events 2.1
     A reaction: You might reply that the object, and maybe the attribute, are concrete, and the time is natural, but the combination really is an abstraction, even though it is located (like the equator). Where is the set of my books located?
Since properties like self-identity and being 2+2=4 are timeless, Kim must restrict his properties [Simons on Kim]
     Full Idea: Since some tautologously universal properties such as self-identity or being such that 2+2=4 apply to all things at all times, that is stretching Kim's events too far. Candidate properties need to be realistically restricted, and it is unclear how.
     From: comment on Jaegwon Kim (Events as property exemplifications [1976]) by Peter Simons - Events 2.1
     A reaction: You could deploy Schoemaker's concept of natural properties in terms of the source of causal powers, but the problem would be that you were probably hoping to then use Kim's events to define causation. Answer: treat causation as the primitive.
Kim's theory results in too many events [Simons on Kim]
     Full Idea: The criticism most frequently levelled against Kim's theory is that it results in an unacceptable plurality of finely differentiated events, because of the requirement for identity of the constituent property.
     From: comment on Jaegwon Kim (Events as property exemplifications [1976]) by Peter Simons - Events 4.4
     A reaction: This may mean that the Battle of Waterloo was several trillion events, which seems daft to the historian, but it doesn't to the physicist. A cannon firing is indeed an accumulation of lots of little events.
For Kim, events are exemplifications of properties by objects at particular times [Kim, by Psillos]
     Full Idea: A dominant view, attributed mainly to Kim, is that events are exemplifications of properties by objects at particular times.
     From: report of Jaegwon Kim (Causes and Events: Mackie on causation [1971]) by Stathis Psillos - Causation and Explanation §2.6
     A reaction: The obvious thought is that we might not describe something as an 'event' just because a property was exemplified (seeing red?). And WWII was an event, but a bit more than a 'property exemplification'.
The induction problem fades if you work with things, rather than with events [Harré/Madden]
     Full Idea: By a shift from events to things we claim to make the big problem of induction tractable.
     From: Harré,R./Madden,E.H. (Causal Powers [1975], 4.II)
     A reaction: [You'll have to read their chapter to get the whole picture] The idea of basing a metaphysics on 'events' gives me the creeps, given the difficulty of individuating an event. Events are not primitive; even animals can analyse their components.
An event is a property of a unique space-time region [Lewis]
     Full Idea: I propose to identify an event with a property, or in other words with a class, a unique spatio-temporal region corresponding to where that event occurs.
     From: David Lewis (Events [1986], II)
     A reaction: [I've run together two separate bits, on p.244 and 245] Lewis cites Montague's similar view, that events are properties of times.
An event is a change in or to an object [Lombard, by Mumford]
     Full Idea: Lombard holds that an event is a change in or to an object.
     From: report of Lawrence B. Lombard (Events [1986]) by Stephen Mumford - Laws in Nature 2.1
     A reaction: This strikes me as more plausible than Davidson's view that events are primitive, or Kim's that they are exemplifications of properties. Events then exist just insofar as we wish to (or are able to) discriminate them.
Events are trope-sequences, in which tropes replace one another [Campbell,K]
     Full Idea: Events are widely acknowledged to be particulars, but they are plainly not ordinary concrete particulars. They are best viewed as trope-sequences, in which one condition gives way to another. They are changes in which tropes replace one another.
     From: Keith Campbell (The Metaphysic of Abstract Particulars [1981], §3)
     A reaction: If nothing exists except bundles of tropes, it is worth asking WHY one trope would replace another. Some tropes are active (i.e. they are best described as 'powers').
Maybe an event is the exemplification of a property at a time [Lowe]
     Full Idea: Maybe an event is the exemplification of a property at a time.
     From: E.J. Lowe (A Survey of Metaphysics [2002], p.229)
     A reaction: What exactly would 'exemplify' mean here? This probably turns out to be circular when you attempt to explain what a property is.
Events are changes in the properties of or relations between things [Lowe]
     Full Idea: My own preference is for a conception of events which reduces them to changes in the properties of or relations between things.
     From: E.J. Lowe (A Survey of Metaphysics [2002], p.245)
     A reaction: Changes of property and changes of relations are two very different things. Is a 'near miss' an event? If so, is any movement an event? If movement is relative, then so are events.
