1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
One system has properties, powers, events, similarity and substance [Shoemaker]
     Full Idea: There is a system of internally related concepts containing the notion of a property, the notion of a causal power, the concept of an event, the concept of similarity, and the concept of a persisting substance.
     From: Sydney Shoemaker (Causality and Properties [1980], §07)
     A reaction: A nice example of a modern metaphysical system, one which I find fairly congenial. His notion of events is Kim's, which involves his properties. The persisting substance is the one I am least clear about.
1. Philosophy / F. Analytic Philosophy / 4. Conceptual Analysis
Analysis aims at internal relationships, not reduction [Shoemaker]
     Full Idea: The goal of philosophical analysis should not be reductive analysis but rather the charting of internal relationships.
     From: Sydney Shoemaker (Causality and Properties [1980], §07)
     A reaction: See Idea 8558 for an attempt by Shoemaker himself. The idea that there has never been a successful analysis has become a truism among pessimistic analytic philosophers. But there are wonderful relationship maps (Quine, Davidson, Lewis, Lowe).
2. Reason / A. Nature of Reason / 8. Naturalising Reason
A standard naturalist view is realist, externalist, and computationalist, and believes in rationality [Fodor]
     Full Idea: There seems to be an emerging naturalist consensus that is Realist in ontology and epistemology, externalist in semantics, and computationalist in cognitive psychology, which nicely allows us to retain our understanding of ourselves as rational creatures.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
3. Truth / A. Truth Problems / 5. Truth Bearers
Psychology has to include the idea that mental processes are typically truth-preserving [Fodor]
     Full Idea: A psychology that can't make sense of such facts as that mental processes are typically truth-preserving is ipso facto dead in the water.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3)
3. Truth / B. Truthmakers / 5. What Makes Truths / a. What makes truths
We might use 'facta' to refer to the truth-makers for facts [Mellor, by Schaffer,J]
     Full Idea: Mellor offers a distinction between 'facts' and 'facta' (the latter being the truth-makers for facts).
     From: report of D.H. Mellor (The Facts of Causation [1995]) by Jonathan Schaffer - The Metaphysics of Causation 1.1
     A reaction: The idea is that 'facta' can do the work in causation, because 'facts' are not part of the world. This seems a very helpful terminology, which should be encouraged, since 'fact' is plainly ambiguous in current usage.
5. Theory of Logic / A. Overview of Logic / 4. Pure Logic
Inferences are surely part of the causal structure of the world [Fodor]
     Full Idea: Inferences are surely part of the causal structure of the world.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §3)
8. Modes of Existence / B. Properties / 1. Nature of Properties
Formerly I said properties are individuated by essential causal powers and causing instantiation [Shoemaker, by Shoemaker]
     Full Idea: My 1980 paper said properties are individuated by causal features - the contribution they make to the causal powers of things, and also how their instantiation can be caused. Collectively, these causal features are the essence of a property.
     From: report of Sydney Shoemaker (Causality and Properties [1980], I) by Sydney Shoemaker - Causal and Metaphysical Necessity
     A reaction: The later paper worries about uncertainty over individuation. The view I favour is that 'powers' is a much better term for what is basic, and this allows 'properties' to be the complex notion we use in real life, as innumberable power-combinations.
8. Modes of Existence / B. Properties / 5. Natural Properties
Genuine properties are closely related to genuine changes [Shoemaker]
     Full Idea: Our intuitions as to what are, and what are not, genuine properties are closely related to our intuitions as to what are, and what are not, genuine changes.
     From: Sydney Shoemaker (Causality and Properties [1980], §02)
     A reaction: A simple but brilliant insight. Somehow we must hack through the plethora of bogus properties and get to the real ones, cutting nature at the joints. Here we have the principle needed for the task.
Properties must be essentially causal if we can know and speak about them [Shoemaker]
     Full Idea: Only if some causal theory of properties is true can it be explained how properties are capable of engaging our knowledge, and our language, in the way they do.
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: Exactly. This also the reason why epiphenomenalism doesn't make sense about consciousness (Idea 7379). The fact that something has causal powers doesn't mean that it just IS a causal power. A bomb isn't an explosion.
To ascertain genuine properties, examine the object directly [Shoemaker]
     Full Idea: There is a plausible way of distinguishing genuine and mere-Cambridge properties. To decide whether an emerald is green the thing to do is to examine it, but a mere-Cambridge property is settled by observations at a remote time and place.
     From: Sydney Shoemaker (Causality and Properties [1980], §06)
     A reaction: Scientific essentialism is beautifully simple! Schoemaker is good at connecting the epistemology to the ontology. If you examined a mirror, you might think it contained reflections.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
We should abandon the idea that properties are the meanings of predicate expressions [Shoemaker]
     Full Idea: I think we should abandon the idea that properties are the meanings of predicate expressions.
     From: Sydney Shoemaker (Causality and Properties [1980], §04)
     A reaction: Right. I have Shoemaker on my side, and he is a distinguished and senior member of the philosophical community. I don't just prefer not to use 'predicate' and 'property' indistinguishably - philosophers should really really give it up!
Some truths are not because of a thing's properties, but because of the properties of related things [Shoemaker]
     Full Idea: Sometimes a predicate is true of a thing, not because (or only because) of any properties it has, but because something else, perhaps something related to it in certain ways, has certain properties.
     From: Sydney Shoemaker (Causality and Properties [1980], §02)
     A reaction: I'm on mission to prize predicates and properties apart, and the strategy is to focus on what is true of something, given that this may not ascribe a property to the thing.
8. Modes of Existence / C. Powers and Dispositions / 3. Powers as Derived
Things have powers in virtue of (which are entailed by) their properties [Shoemaker]
     Full Idea: There is a distinction between powers, and the properties in virtue of which things have they powers they have (n8: 'in virtue of' means that there is a lawlike truth, which turns out to be the properties entailing the powers).
     From: Sydney Shoemaker (Causality and Properties [1980], §03)
     A reaction: To me this is an ontology which rests something very clear (a power) on something very indeterminate (a 'property').
One power can come from different properties; a thing's powers come from its properties [Shoemaker]
     Full Idea: It is possible to have the same power (e.g. being poisonous) in virtue of having very different properties. ..So it is in virtue of a thing's properties that the thing has the powers that it has.
     From: Sydney Shoemaker (Causality and Properties [1980], §03)
     A reaction: This strikes me as an accurate and helpful picture. It means that true properties give rise to powers, and categorial or relational or whimsical properties must have their ontological status judged by that standard.
Properties are functions producing powers, and powers are functions producing effects [Shoemaker]
     Full Idea: Powers are functions from circumstances to causal effects, and properties (on which powers depend) can be thought of as functions from sets of properties to sets of powers. Maybe we should call properties 'second-order powers', as they produce powers.
     From: Sydney Shoemaker (Causality and Properties [1980], §04)
     A reaction: He presents property as both a function, and a component of the function. This is the core picture on which modern scientific essentialism is built. See under Natural Theory|Laws of Nature.
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Shoemaker says all genuine properties are dispositional [Shoemaker, by Ellis]
     Full Idea: I am against Shoemaker's strong dispositionalism, according to which all genuine properties are dispositional.
     From: report of Sydney Shoemaker (Causality and Properties [1980]) by Brian Ellis - The Metaphysics of Scientific Realism 3
     A reaction: This is because Ellis argues that some properties are categorical, and are needed to underly the active dispositional ones. I think I side with Shoemaker, but this needs more thought.
A causal theory of properties focuses on change, not (say) on abstract properties of numbers [Shoemaker]
     Full Idea: My account of properties concerns those with respect to which change is possible; it is not intended to apply to such properties of numbers as being even and being prime.
     From: Sydney Shoemaker (Causality and Properties [1980], §02)
     A reaction: You could argue that while these properties may not cause change, they are abstract powers. Being even allows division by 2, and being prime blocks it. I say patterns are the basis, and dividing groups of physical objects is involved.
'Square', 'round' and 'made of copper' show that not all properties are dispositional [Shoemaker]
     Full Idea: Surely we make a distinction beween dispositional and nondispositional properties, and can mention paradigms of both sorts. ....It seems plain that predicates like 'square', 'round' and 'made of copper' are not dispositional.
     From: Sydney Shoemaker (Causality and Properties [1980], §03)
     A reaction: It might be possible to account for squareness and roundness in dispositional ways, and it is certainly plausible to say that 'made of copper' is not a property (even when it is a true predicate).
The identity of a property concerns its causal powers [Shoemaker]
     Full Idea: What makes a property the property it is, what determines its identity, is its potential for contributing to the causal powers of the things that have it.
     From: Sydney Shoemaker (Causality and Properties [1980], §04)
     A reaction: Does this mean that the 'potential' to act is the essence of the property, or is a property of the property, or is wholly identical with the property? Or is this just epistemological - whatever individuates the property for observers?
Properties are clusters of conditional powers [Shoemaker]
     Full Idea: A thing has a 'conditional power' when it has a power conditionally upon the possession of certain properties. ...We can then express my view by saying that properties are clusters of conditional powers.
     From: Sydney Shoemaker (Causality and Properties [1980], §04)
     A reaction: His example is a knife-shaped thing, which conditionally cuts wood if it is made of steel. Shoemaker rejected this in 1998. Mumford/Anjum prefer the earlier view. Which is fundamental? Powers are simple and primitive. Properties are complex.
Could properties change without the powers changing, or powers change without the properties changing? [Shoemaker]
     Full Idea: Could a thing undergo radical change with respect to its properties without undergoing any change in its causal powers, or undergo radical change in its causal powers without undergoing any change in the properties that underlie these powers?
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: I don't accept properties underlying powers, but these two questions at least force us to see how closely the two are linked.
If properties are separated from causal powers, this invites total elimination [Shoemaker]
     Full Idea: The disassociation of property identity from causal potentiality is an invitation to eliminate reference to properties from our explanatory hypotheses altogether.
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: Just as epiphenomenalism about consciousness is a step towards eliminativism. This seems to describe Quine's reaction to Goodman, in moving from predicate nominalism to elimination of properties. I agree with Shoemaker.
The notions of property and of causal power are parts of a single system of related concepts [Shoemaker]
     Full Idea: The notion of a property and the notion of a causal power belong to a system of internally related concepts, no one of which can be explicated without the use of the other.
     From: Sydney Shoemaker (Causality and Properties [1980], §07)
     A reaction: Sounds good. It is hard to conceive of a property which has no causal powers, or a causal power that doesn't arise from a property.
Actually, properties are individuated by causes as well as effects [Shoemaker]
     Full Idea: I should probably modify my view, and say that properties are individuated by their possible causes as well as by their possible effects.
     From: Sydney Shoemaker (Causality and Properties [1980], §11)
     A reaction: (This is in an afterword responding to criticism by Richard Boyd) He doesn't use the word 'individuate' in the essay. That term always strikes me as smacking too much of epistemology, and not enough of ontology. Who cares how you individuate something?
8. Modes of Existence / C. Powers and Dispositions / 6. Dispositions / b. Dispositions and powers
Dispositional predicates ascribe powers, and the rest ascribe properties [Shoemaker]
     Full Idea: By and large, dispositional predicates ascribe powers while nondispositional monadic predicates ascribe properties that are not powers in the same sense.
     From: Sydney Shoemaker (Causality and Properties [1980], §03)
     A reaction: The powers are where the properties come into contact with the rest of the world, so you would expect dispositions to be found at that level, rather than at the deeper level of properties. Sounds good to me.
8. Modes of Existence / D. Universals / 2. Need for Universals
Universals concern how things are, and how they could be [Shoemaker, by Bird]
     Full Idea: Shoemaker contends that universals concern the way things could be, not merely the way any things actually are.
     From: report of Sydney Shoemaker (Causality and Properties [1980]) by Alexander Bird - Nature's Metaphysics 3.2.2
     A reaction: If you want to retain universals within a scientific essentialist view (and I would rather not), then this seems like the only way to go.
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
Triangular and trilateral are coextensive, but different concepts; but powers and properties are the same [Shoemaker]
     Full Idea: It is natural to say that 'being triangular' and 'being trilateral', though necessarily coextensive, are different properties. But what are distinct are the concepts and meanings. If properties are not meanings of predicates, these are identical.
     From: Sydney Shoemaker (Causality and Properties [1980], §04)
     A reaction: A good test example. Being renate (kidney) and being cordate (heart) are different, because being cordate produces a thumping noise. Shoemaker's example is pretty much Phosphorus/Hesperus.
9. Objects / D. Essence of Objects / 15. Against Essentialism
There is no subset of properties which guarantee a thing's identity [Shoemaker]
     Full Idea: There is, putting aside historical properties and 'identity properties', no subset of the properties of a thing which constitutes an individual essence, so that having those properties is necessary and sufficient for being that particular thing.
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: He asserts this rather dogmatically. If he says a thing can lose its essence, I agree, but it seems to me that there must be a group of features which will guarantee that (if they are present) it has that identity.
10. Modality / B. Possibility / 1. Possibility
Possible difference across worlds depends on difference across time in the actual world [Shoemaker]
     Full Idea: The ways in which a given thing can be different in different possible worlds depend on the ways in which such a thing can be different at different times in the actual world.
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: Where change in a thing is possible across time in the actual world seems to require a combination of experiment and imagination. Unimaginability does not entail necessity, but it may be the best guide we have got.
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / a. Conceivable as possible
'Conceivable' is either not-provably-false, or compatible with what we know? [Shoemaker]
     Full Idea: We could use 'conceivable' to say it is not provable that it is not the case, or we could use it to say that it is compatible with what we know.
     From: Sydney Shoemaker (Causality and Properties [1980], §10)
     A reaction: Rather significant, since the first one would seem to allow in a great deal that the second one would rule out. Any disproof of some natural possibility founders on the remark that 'you never know'.
10. Modality / D. Knowledge of Modality / 4. Conceivable as Possible / b. Conceivable but impossible
It is possible to conceive what is not possible [Shoemaker]
     Full Idea: It is possible to conceive what is not possible.
     From: Sydney Shoemaker (Causality and Properties [1980], §10)
     A reaction: The point here is that, while we cannot clearly conceive the impossible in a world like mathematics, we can conceive of impossible perceptions in the physical world, such as a bonfire burning under water.
13. Knowledge Criteria / C. External Justification / 5. Controlling Beliefs
Control of belief is possible if you know truth conditions and what causes beliefs [Fodor]
     Full Idea: Premeditated cognitive management is possible if knowing the contents of one's thoughts would tell you what would make them true and what would cause you to have them.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: I love the idea of 'cognitive management'. Since belief is fairly involuntary, I subject myself to the newspapers, books, TV and conversation which will create the style of beliefs to which I aspire. Why?
14. Science / A. Basis of Science / 3. Experiment
We can deliberately cause ourselves to have true thoughts - hence the value of experiments [Fodor]
     Full Idea: A creature that knows what makes its thoughts true and what would cause it to have them, could therefore cause itself to have true thoughts. …This would explain why experimentation is so close to the heart of our cognitive style.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
Interrogation and experiment submit us to having beliefs caused [Fodor]
     Full Idea: You can put yourself into a situation where you may be caused to believe that P. Putting a question to someone who is in the know is one species of this behaviour, and putting a question to Nature (an experiment) is another.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
Participation in an experiment requires agreement about what the outcome will mean [Fodor]
     Full Idea: To be in the audience for an experiment you have to believe what the experimenter believes about what the outcome would mean, but not necessarily what the outcome will be.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
An experiment is a deliberate version of what informal thinking does all the time [Fodor]
     Full Idea: Experimentation is an occasional and more or less self-conscious exercise in what informal thinking does all the time without thinking about it.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
14. Science / B. Scientific Theories / 1. Scientific Theory
Theories are links in the causal chain between the environment and our beliefs [Fodor]
     Full Idea: Theories function as links in the causal chains that run from environmental outcomes to the beliefs that they cause the inquirer to have.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
Grueness is not, unlike green and blue, associated with causal potential [Shoemaker]
     Full Idea: Grueness, as defined by Goodman, is not associated in the way greenness and blueness are with causal potentialities.
     From: Sydney Shoemaker (Causality and Properties [1980], §06)
     A reaction: Expressed rather more simply in Idea 7296. 'Grue' is a characteristic production of a predicate nominalist (i.e. Goodman), and that theory is just wrong. The account of properties must mesh with the account of induction.
15. Nature of Minds / A. Nature of Mind / 1. Mind / e. Questions about mind
I say psychology is intentional, semantics is informational, and thinking is computation [Fodor]
     Full Idea: I hold that psychological laws are intentional, that semantics is purely informational, and that thinking is computation (and that it is possible to hold all of these assumptions at once).
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: When he puts it baldly like that, it doesn't sound terribly persuasive. Thinking is 'computation'? Raw experience is irrelevant? What is it 'like' to spot an interesting connection between two propositions or concepts? It's not like adding 7 and 5.
15. Nature of Minds / B. Features of Minds / 1. Consciousness / f. Higher-order thought
We are probably the only creatures that can think about our own thoughts [Fodor]
     Full Idea: I think it is likely that we are the only creatures that can think about the contents of our thoughts.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: I think this is a major idea. If you ask me the traditional question - what is the essential difference between us and other animals? - this is my answer (not language, or reason). We are the metathinkers.
17. Mind and Body / A. Mind-Body Dualism / 2. Interactionism
Semantics v syntax is the interaction problem all over again [Fodor]
     Full Idea: The question how mental representations could be both semantic, like propositions, and causal, like rocks, trees, and neural firings, is arguably just the interaction problem all over again.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: Interesting way of presenting the problem. If you seem to be confronting the interaction problem, you have probably drifted into a bogus dualist way of thinking. Retreat, and reformulate you questions and conceptual apparatus, till the question vanishes.
Cartesians consider interaction to be a miracle [Fodor]
     Full Idea: The Cartesian view is that the interaction problem does arise, but is unsolvable because interaction is miraculous.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: A rather unsympathetic statement of the position. Cartesians might think that God could explain to us how interaction works. Cartesians are not mysterians, I think, but they see no sign of any theory of interaction.
17. Mind and Body / E. Mind as Physical / 1. Physical Mind
Type physicalism equates mental kinds with physical kinds [Fodor]
     Full Idea: Type physicalism is, roughly, the doctrine that psychological kinds are identical to neurological kinds.
     From: Jerry A. Fodor (The Elm and the Expert [1993], App A n.1)
     A reaction: This gets my general support, leaving open the nature of 'kinds'. Presumably the identity is strict, as in 'Hesperus is identical to Phosphorus'. It seems unlikely that if you and I think the 'same' thought, that we have strictly identical brain states.
17. Mind and Body / E. Mind as Physical / 4. Connectionism
Hume has no theory of the co-ordination of the mind [Fodor]
     Full Idea: What Hume didn't see was that the causal and representational properties of mental symbols have somehow to be coordinated if the coherence of mental life is to be accounted for.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: Certainly the idea that it all somehow becomes magic at the point where the brain represents the world is incoherent - but it is a bit magical. How can the whole of my garden be in my brain? Weird.
18. Thought / A. Modes of Thought / 2. Propositional Attitudes
Propositional attitudes are propositions presented in a certain way [Fodor]
     Full Idea: Propositional attitudes are really three-place relations, between a creature, a proposition, and a mode of presentation (which are sentences of Mentalese).
     From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II)
     A reaction: I'm not sure about 'really'! Why do we need a creature? Isn't 'hoping it will rain' a propositional attitude which some creature may or may not have? Fodor wants it to be physical, but it's abstract?
18. Thought / A. Modes of Thought / 5. Rationality / a. Rationality
Rationality has mental properties - autonomy, productivity, experiment [Fodor]
     Full Idea: Mentalism isn't gratuitous; you need it to explain rationality. Mental causation buys you behaviours that are unlike reflexes in at least three ways: they're autonomous, they're productive, and they're experimental.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: He makes his three ways sound all-or-nothing, which is (I believe) the single biggest danger when thinking about the mind. "Either you are conscious, or you are not..."
18. Thought / C. Content / 5. Twin Earth
XYZ (Twin Earth 'water') is an impossibility [Fodor]
     Full Idea: There isn't any XYZ, and there couldn't be any, and so we don't have to worry about it.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I)
     A reaction: Jadeite and Nephrite are real enough, which are virtually indistinguishable variants of jade. You just need Twin Jewellers instead of Twin Earths. We could build them, and employ twins to work there.
18. Thought / C. Content / 6. Broad Content
Truth conditions require a broad concept of content [Fodor]
     Full Idea: We need the idea of broad content to make sense of the fact that thoughts have the truth-conditions that they do.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §2.II)
     A reaction: There seems to be (as Dummett points out) a potential circularity here, as you can hardly know the truth-conditions of something if you don't already know its content.
18. Thought / C. Content / 7. Narrow Content
Concepts aren't linked to stuff; they are what is caused by stuff [Fodor]
     Full Idea: If the words of 'Swamp Man' (spontaneously created, with concepts) are about XYZ on Twin Earth, it is not because he's causally connected to the stuff, but because XYZ would cause his 'water' tokens (in the absence of H2O).
     From: Jerry A. Fodor (The Elm and the Expert [1993], App B)
     A reaction: The sight of the Eiffel tower causes my 'France' tokens, so is my word "France" about the Eiffel Tower? What would cause my 'nothing' tokens?
18. Thought / C. Content / 10. Causal Semantics
Knowing the cause of a thought is almost knowing its content [Fodor]
     Full Idea: If you know the content of a thought, you know quite a lot about what would cause you to have it.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: I'm not sure where this fits into the great jigsaw of the mind, but it strikes me as an acute and important observation. The truth of a thought is not essential to make you have it. Ask Othello.
18. Thought / C. Content / 12. Informational Semantics
Is content basically information, fixed externally? [Fodor]
     Full Idea: I assume intentional content reduces (in some way) to information. …The content of a thought depends on its external relations; on the way that the thought is related to the world, not the way that it is related to other thoughts.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2)
     A reaction: Does this make Fodor a 'weak' functionalist? The 'strong' version would say a thought is merely a location in a flow diagram, but Fodor's 'mentalism' includes a further 'content' in each diagram box.
18. Thought / D. Concepts / 3. Ontology of Concepts / b. Concepts as abilities
In the information view, concepts are potentials for making distinctions [Fodor]
     Full Idea: Semantics, according to the informational view, is mostly about counterfactuals; what counts for the identity of my concepts is not what I do distinguish but what I could distinguish if I cared to (even using instruments and experts).
     From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I)
     A reaction: We all differ in our discriminations (and awareness of expertise), so our concepts would differ, which is bad news for communication (see Idea 223). The view has some plausibility, though.
19. Language / A. Nature of Meaning / 1. Meaning
Semantic externalism says the concept 'elm' needs no further beliefs or inferences [Fodor]
     Full Idea: It is the essence of semantic externalism that there is nothing that you have to believe, there are no inferences that you have to accept, to have the concept 'elm'.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §2.I)
     A reaction: [REMINDER: broad content is filed in 18.C.7, under 'Thought' rather than under language. That is because I am a philospher of thought, rather than of language.
If meaning is information, that establishes the causal link between the state of the world and our beliefs [Fodor]
     Full Idea: It is the causal connection between the state of the world and the contents of beliefs that the reduction of meaning to information is designed to insure.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: I'm not clear why characterising the contents of a belief in terms of its information has to amount to a 'reduction'. A cup of tea isn't reduced to tea. Connections imply duality.
19. Language / A. Nature of Meaning / 4. Meaning as Truth-Conditions
To know the content of a thought is to know what would make it true [Fodor]
     Full Idea: If you know the content of a thought, you thereby know what would make the thought true.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: The truthmaker might by physically impossible, and careful thought might show it to be contradictory - but that wouldn't destroy the meaning.
19. Language / A. Nature of Meaning / 7. Meaning Holism / b. Language holism
For holists no two thoughts are ever quite the same, which destroys faith in meaning [Fodor]
     Full Idea: If what you are thinking depends on all of what you believe, then nobody ever thinks the same thing twice. …That is why so many semantic holists (Quine, Putnam, Rorty, Churchland, probably Wittgenstein) end up being semantic eliminativists.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b)
     A reaction: If linguistic holism is nonsense, this is easily settled. What I say about breakfast is not changed by reading some Gibbon yesterday.
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
It is claimed that reference doesn't fix sense (Jocasta), and sense doesn't fix reference (Twin Earth) [Fodor]
     Full Idea: The standard view is that Frege cases [knowing Jocasta but not mother] show that reference doesn't determine sense, and Twin cases [knowing water but not H2O] show that sense doesn't determine reference.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.3)
     A reaction: How about 'references don't contain much information', and 'descriptions may not fix what they are referring to'? Simple really.
19. Language / C. Assigning Meanings / 2. Semantics
Broad semantics holds that the basic semantic properties are truth and denotation [Fodor]
     Full Idea: Broad semantic theories generally hold that the basic semantic properties of thoughts are truth and denotation.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §1.2b)
     A reaction: I think truth and denotation are the basic semantic properties, but I am dubious about whole-hearted broad semantic theories, so I seem to have gone horribly wrong somewhere.
19. Language / C. Assigning Meanings / 6. Truth-Conditions Semantics
Externalist semantics are necessary to connect the contents of beliefs with how the world is [Fodor]
     Full Idea: You need an externalist semantics to explain why the contents of beliefs should have anything to do with how the world is.
     From: Jerry A. Fodor (The Elm and the Expert [1993], §4)
     A reaction: Since externalist semantics only emerged in the 1970s, that implies that no previous theory had any notion that language had some connection to how the world is. Eh?
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
If causality is between events, there must be reference to the properties involved [Shoemaker]
     Full Idea: Any account of causality as a relation between events should involve, in a central way, reference to the properties of the constituent objects of the events.
     From: Sydney Shoemaker (Causality and Properties [1980], §01)
     A reaction: This remark, with which I wholeheartedly agree, is aimed at Davidson, who seems to think you need know no more about an event than the way in which someone chooses to describe it. Metaphysics must dig deeper, even if science can't.
Causal statements relate facts (which are whatever true propositions express) [Mellor, by Psillos]
     Full Idea: Mellor argues that causal statements relate facts, where facts may be seen as whatever true propositions express.
     From: report of D.H. Mellor (The Facts of Causation [1995]) by Stathis Psillos - Causation and Explanation §2.6
     A reaction: Choose between 'facts', 'objects', 'conserved quantities, 'events' (the usual one) or 'processes'. I rather like processes (Salmon) as they are a better prospect as the building blocks of an ontology.
26. Natural Theory / C. Causation / 8. Particular Causation / e. Probabilistic causation
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.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / b. Scientific necessity
If causal laws describe causal potentialities, the same laws govern properties in all possible worlds [Shoemaker]
     Full Idea: To the extent that causal laws can be viewed as propositions describing the causal potentialities of properties, it is impossible that the same properties should be governed by different causal laws in different possible worlds.
     From: Sydney Shoemaker (Causality and Properties [1980], §08)
     A reaction: [He has just asserted that causal potentialities are essential to properties] This is the dramatic basic claim of scientific essentialism, which grows out of Shoemaker's causal account of properties. Note that the laws are just descriptions.
If properties are causal, then causal necessity is a species of logical necessity [Shoemaker]
     Full Idea: My theory of properties as causal appears to have the consequence that causal laws are logically necessary, and that causal necessity is just a species of logical necessity.
     From: Sydney Shoemaker (Causality and Properties [1980], §09)
     A reaction: Where he writes 'logical' necessity I would claim that he really means 'metaphysical' necessity. The point, I take it, is that given the existence of those properties, certain causal efforts must always follow from them. I agree.
If a world has different causal laws, it must have different properties [Shoemaker]
     Full Idea: If there are worlds in which the causal laws are different from those that prevail in this world, ..then the properties will have to be different as well.
     From: Sydney Shoemaker (Causality and Properties [1980], §09)
     A reaction: The next question is whether the same stuff (e.g. gold or water) could have different properties, and I take the the scientific essentialism answer to be 'no'. So the actual stuff (substances?) would have to be different.
26. Natural Theory / D. Laws of Nature / 8. Scientific Essentialism / d. Knowing essences
It looks as if the immutability of the powers of a property imply essentiality [Shoemaker]
     Full Idea: There is a prima facie case for saying that the immutability of the causal potentialities of a property implies their essentiality. ...If they cannot vary across time, they also cannot vary across possible worlds.
     From: Sydney Shoemaker (Causality and Properties [1980], §05)
     A reaction: This is only the beginning of scientific essentialism, but one of the targets is to save the phenomena. It is also involves unimaginability (of different powers from a given property) implying necessity.
