That Queen Anne is dead is a 'general fact', not a fact about Queen Anne [Prior,AN]
|
|
Full Idea:
The fact that Queen Anne has been dead for some years is not, in the strict sense of 'about', a fact about Queen Anne; it is not a fact about anyone or anything - it is a general fact.
|
|
From:
Arthur N. Prior (Changes in Events and Changes in Things [1968], p.13), quoted by Robin Le Poidevin - Past, Present and Future of Debate about Tense 1 b
|
|
A reaction:
He distinguishes 'general facts' (states of affairs, I think) from 'individual facts', involving some specific object. General facts seem to be what are expressed by negative existential truths, such as 'there is no Loch Ness Monster'. Useful.

If 'red' is vague, then membership of the set of red things is vague, so there is no set of red things [Sainsbury]
|
|
Full Idea:
Sets have sharp boundaries, or are sharp objects; an object either definitely belongs to a set, or it does not. But 'red' is vague; there objects which are neither definitely red nor definitely not red. Hence there is no set of red things.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §2)
|
|
A reaction:
Presumably that will entail that there IS a set of things which can be described as 'definitely red'. If we describe something as 'definitely having a hint of red about it', will that put it in a set? In fact will the applicability of 'definitely' do?

We should abandon classifying by pigeon-holes, and classify around paradigms [Sainsbury]
|
|
Full Idea:
We must reject the classical picture of classification by pigeon-holes, and think in other terms: classifying can be, and often is, clustering round paradigms.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §8)
|
|
A reaction:
His conclusion to a discussion of the problem of vagueness, where it is identified with concepts which have no boundaries. Pigeon-holes are a nice exemplar of the Enlightenment desire to get everything right. I prefer Aristotle's categories, Idea 3311.
|
|
8984
|
If concepts are vague, people avoid boundaries, can't spot them, and don't want them [Sainsbury]
|
|
Full Idea:
Vague concepts are boundaryless, ...and the manifestations are an unwillingness to draw any such boundaries, the impossibility of identifying such boundaries, and needlessness and even disutility of such boundaries.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §5)
|
|
A reaction:
People have a very fine-tuned notion of whether the sharp boundary of a concept is worth discussing. The interesting exception are legal people, who are often forced to find precision where everyone else hates it. Who deserves to inherit the big house?

Boundaryless concepts tend to come in pairs, such as child/adult, hot/cold [Sainsbury]
|
|
Full Idea:
Boundaryless concepts tend to come in systems of contraries: opposed pairs like child/adult, hot/cold, weak/strong, true/false, and complex systems of colour terms. ..Only a contrast with 'adult' will show what 'child' excludes.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §5)
|
|
A reaction:
This might be expected. It all comes down to the sorites problem, of when one thing turns into something else. If it won't merge into another category, then presumably the isolated concept stays applicable (until reality terminates it? End of sheep..).

In causation there are three problems of relata, and three metaphysical problems [Schaffer,J]
|
|
Full Idea:
The questions about causation concern their relata (in space-time, how fine-grained, how many?) and the metaphysics (distinguish causal sequences from others, the direction of causation, selecting causes among pre-conditions?).
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], Intro)
|
|
A reaction:
A very nice map (which has got me thinking about restructuring this database). I can't think of a better way to do philosophy than this (let's hear it for analysis - but the greatest role models for the approach are Aristotle and Aquinas).

Causation may not be transitive; the last event may follow from the first, but not be caused by it [Schaffer,J]
|
|
Full Idea:
It is not clear whether causation is transitive. For example, if a boulder roll's towards a hiker's head, causing the hiker to duck, which causes the hiker to survive, it does not seem that the rolling boulder causes the survival of the hiker.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1.2)
|
|
A reaction:
Maybe survival is not an event or an effect. How many times have I survived in my life? We could, though, say that the hiker strained a muscle as he or she ducked. But then it is unclear whether the boulder caused the muscle-strain.
|

There are at least ten theories about causal connections [Schaffer,J]
|
|
Full Idea:
Theories of causal connection are: nomological subsumption, statistical correlation, counterfactual dependence, agential manipulability, contiguous change, energy flow, physical processes, property transference, primitivism and eliminativism.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1.3.1)
|
|
A reaction:
Schaffer reduces these to probability and process. I prefer the latter. The first two are wrong, the third right but superficial, the fourth wrong, the fifth, sixth and seventh on the right lines, the eighth wrong, the ninth tempting, and the last wrong.
|
|
10377
|
Causation may not be a process, if a crucial part of the process is 'disconnected' [Schaffer,J]
|
|
Full Idea:
One problem case for the process view of causation is 'disconnection'. If a brick breaks a window by being fired from a catapult, a latch is released which was preventing the catapult from firing, so the 'process' is just internal to the catapult.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.1)
|
|
A reaction:
Schaffer says the normal reply is to deny that the catch-releasing is genuinely causal. I would have thought we should go more fine-grained, and identify linked components of the causal process.
|

At least four rivals have challenged the view that causal direction is time direction [Schaffer,J]
|
|
Full Idea:
The traditional view that the direction of causation is the direction of time has been challenged, by the direction of forking, by overdetermination, by independence, and by manipulation, which all seem to be one-directional features.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1.3.1)
|
|
A reaction:
Personally I incline to the view that time is prior, and fixes the direction of causation. I'm not sure that 'backward causation' can be stated coherently, even if it is metaphysically or naturally possible.
|
|
10389
|
Causal order must be temporal, or else causes could be blocked, and time couldn't be explained [Schaffer,J]
|
|
Full Idea:
Reasons for causal order being temporal order are that otherwise the effect might occur but the cause then get prevented, ..and that they must be the same, because the temporal order can only be analysed in terms of the causal order.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.2)
|
|
A reaction:
If one took both time and causation as primitive, then the second argument would be void. The first argument, though, sounds pretty overwhelming to me.
|
|
10390
|
Causal order is not temporal, because of time travel, and simultanous, joint or backward causes [Schaffer,J]
|
|
Full Idea:
Reasons for denying that causal order is temporal order are that time travel seems possible, that cause and effect can be simultaneous, because joint effects have temporal order without causal connection, and because backward causation may exist.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.2)
|
|
A reaction:
The possibility of time travel and backward causation can clearly be doubted, and certainly can't be grounds for one's whole metaphysics. The other two need careful analysis, but I think they can be answered. Causation is temporal.
|
|

|
Causation is primitive; it is too intractable and central to be reduced; all explanations require it [Schaffer,J]
|
|
Full Idea:
Primitivism arises from our failure to reduce causation, but also from causation being too central to reduce. The probability and process accounts are said to be inevitably circular, as they cannot be understood without reference to causation.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
This is very tempting. The primitive view, though, must deal with the direction problem, which may suggest that time is even more primitive. Can we have a hierarchy of primitiveness? To be alive is to be causal.
|
|
10385
|
If causation is just observables, or part of common sense, or vacuous, it can't be primitive [Schaffer,J]
|
|
Full Idea:
The three main objections to causation being primitive are that causation can't be anything more than what we observe, or that such a primitive is too spooky to be acceptable, or that primitivism leads to elimination of causation.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
[summarised] I don't like the first (Humean) view. I suspect that anything which we finally decide has to be primitive (time, for example) is going to be left looking 'spooky', and I suspect that eliminativism is just Humeanism in disguise.
|
|

|
The notion of causation allows understanding of science, without appearing in equations [Schaffer,J]
|
|
Full Idea:
The concepts of 'event', 'law', 'cause' and 'explanation' are nomic concepts which serve to allow a systematic understanding of science; they do not themselves appear in the equations.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
This is a criticism of Russell's attempt to eliminate causation from science. It shows that there has to be something we can call 'metascience', which is the province of philosophers, since scientists don't have much interest in it.
|
|
10388
|
Causation is utterly essential for numerous philosophical explanations [Schaffer,J]
|
|
Full Idea:
Causation can't be eliminated if it is needed to explain persistence, explanation, disposition, perception, warrant, action, responsibility, mental functional role, conceptual content, and reference. It's elimination would be catastrophic.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
[compressed list] I think I am going to vote for the view that causation is one of the primitives in the metaphysics of nature, so I have to agree with this. Most of the listed items, though, are controversial, so eliminativists are not defeated.
|
|
10384
|
If two different causes are possible in one set of circumstances, causation is primitive [Schaffer,J]
|
|
Full Idea:
Causation seems to be primitive if the same laws and patterns of events might embody three different possible causes, as when two magicians cast the same successful spell, each with a 50% chance of success, and who was successful is unclear.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
I'm cautious when the examples involve magic. It implies that the process that leads to the result will be impossible to observe, but if magic never really happens, then the patterns of events will always be different.
|
|
10386
|
If causation is primitive, it can be experienced in ourselves, or inferred as best explanation [Schaffer,J]
|
|
Full Idea:
The view that causation is primitive can be defended against Humean critics by saying that causation can be directly observed in the will or our bodies, or that it can be inferred as the best explanation.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
I like both views, and have just converted myself to the primitivist view of causation! I can't know the essence of a tree, because I am not a tree, but I can know the essence of causation. The Greek fascination with explaining movement is linked.
|

Events are fairly course-grained (just saying 'hello'), unlike facts (like saying 'hello' loudly) [Schaffer,J]
|
|
Full Idea:
Events are relatively coarse-grained, unlike facts; so the event of John's saying 'hello' seems to be the same event as John's saying 'hello' loudly, while they seem to be different facts.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1)
|
|
A reaction:
The example seems good support for facts, since saying 'hello' loudly could have quite different effects from just saying 'hello'. I also incline temperamentally towards a fine-grained account, because it is more reductivist.
|
|
10360
|
Causal relata are events - or facts, features, tropes, states, situations or aspects [Schaffer,J]
|
|
Full Idea:
The standard view make causal relata events (Davidson, Kim, Lewis), but there is considerable support for facts (Bennett, Mellor), and occasional support for features (Dretske), tropes (Campbell), states of affairs (Armstrong), and situations and aspects.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1)
|
|
A reaction:
An event is presumed to be concrete, while a fact is more abstract (a proposition, perhaps). I'm always drawn to 'processes' (because they are good for discussing the mind), so an event, as a sort of natural process, looks good.
|
|
10368
|
If causal relata must be in nature and fine-grained, neither facts nor events will do [Schaffer,J]
|
|
Full Idea:
Theorists who reject both events and facts as causal relata do so because the relata must be immanent in nature, and thus not facts, but also fine-grained and thus not events.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 1.2)
|
|
A reaction:
Kim, however, offers a fine-grained account of events (as triples), and Bennett individuates them even more finely (as propositions), so events might be saved. Descriptions can be very fine-grained.
|
|
10383
|
The relata of causation (such as events) need properties as explanation, which need causation! [Schaffer,J]
|
|
Full Idea:
The primitivist about causation might say that the notion of an event (or other relata) cannot be understood without reference to causation, because properties themselves are individuated by their causal role.
|
|
From:
Jonathan Schaffer (The Metaphysics of Causation [2007], 2.1.2)
|
|
A reaction:
Having enthusiastically embraced the causal view of properties (see Shoemaker and Ellis), I suddenly realise that I seem required to embrace primitivism about causation, which I hadn't anticipated! I've no immediate problem with that.

'Thank goodness that's over' is not like 'thank goodness that happened on Friday' [Prior,AN]
|
|
Full Idea:
One says 'thank goodness that is over', ..and it says something which it is impossible which any use of any tenseless copula with a date should convey. It certainly doesn't mean the same as 'thank goodness that occured on Friday June 15th 1954'.
|
|
From:
Arthur N. Prior (Changes in Events and Changes in Things [1968]), quoted by Adrian Bardon - Brief History of the Philosophy of Time 4 'Pervasive'
|
|
A reaction:
[Ref uncertain] This seems to be appealing to ordinary usage, in which tenses have huge significance. If we take time (with its past, present and future) as primitive, then tenses can have full weight. Did tenses mean anything at all to Einstein?
