4194 | Metaphysics is concerned with the fundamental structure of reality as a whole [Lowe] |
Full Idea: Metaphysics is concerned with the fundamental structure of reality as a whole. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.2) | |
A reaction: I think it is vital to hang on to this big definition, focusing on ontology, and not retreat (like Kant) to the epistemological question of how humans happen to see reality, even if we are stuck with being humans. |
4214 | Maybe such concepts as causation, identity and existence are primitive and irreducible [Lowe] |
Full Idea: It may well be that after all our attempts at analysis, we have to accept the notions of causality, identity and existence as being primitive and irreducible. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.191) | |
A reaction: They may be irreducible, but it seems possible that the relationships between them might be revealed (as between Platonic Forms). To exist is to have identity and causal powers? |
11159 | My account shows how the concept works, rather than giving an analysis [Fine,K] |
Full Idea: My assimilation of essence to definition ...may not provide us with an analysis of the concept, but it does provide us with a good model of how the concept works. | |
From: Kit Fine (Essence and Modality [1994], p. 3) | |
A reaction: An example of the modern shift in analytic philosophy, away from the dream of given a complete analysis of a concept, towards giving an account of the concepts relationships. Compare Shoemaker in Idea 8559. |
4222 | If all that exists is what is being measured, what about the people and instruments doing the measuring? [Lowe] |
Full Idea: If we think, in a positivistic spirit, that only measurements and observations exist, this is strikingly naïve. The scientists and their instruments can't be composed merely of measurements. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.234) | |
A reaction: A strong rebuff to crude positivism and 'operationalism'. Such mistakes are the usual confusion of epistemology and ontology. |
4217 | It is more extravagant, in general, to revise one's logic than to augment one's ontology [Lowe] |
Full Idea: It is more extravagant, in general, to revise one's logic than to augment one's ontology. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.219) | |
A reaction: Meaning there are stronger principles of thought which can trump Ockham's Razor. A few more entities won't hurt. Sound right. |
11157 | Modern philosophy has largely abandoned real definitions, apart from sortals [Fine,K] |
Full Idea: In modern analytic philosophy we find that, as a result of sustained empiricist critique, the idea of real definition has been more or less given up (unless it be taken to be vestigially present in the notion of a sortal). | |
From: Kit Fine (Essence and Modality [1994], p. 3) | |
A reaction: The account of essences as falling under sortals (roughly, categorising terms) is associated with David Wiggins. Kit Fine is in the business of reviving Aristotelian real definitions, as are fans of scientific essentialism (see under 'Nature'). |
11171 | Defining a term and giving the essence of an object don't just resemble - they are the same [Fine,K] |
Full Idea: There is an analogy between defining a term and giving the essence of an object. ..However, I am inclined to think that the two cases are not merely parallel but are, at bottom, the same. | |
From: Kit Fine (Essence and Modality [1994], p.13) | |
A reaction: The proposal is something like the meaning of a concept being the essence of the concept. And essence is definition. The parallel is that they both lead to necessities, either derived from objects or from concepts. Sounds good to me. |
4229 | An infinite series of tasks can't be completed because it has no last member [Lowe] |
Full Idea: It appears to be impossible to complete an infinite series of tasks, since such a series has, by definition, no last member. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.290) | |
A reaction: This pinpoints the problem. So are there infinite tasks in a paradox of subdivision like the Achilles? |
4240 | It might be argued that mathematics does not, or should not, aim at truth [Lowe] |
Full Idea: It might be argued that mathematics does not, or should not, aim at truth. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.375) | |
A reaction: Intriguing. Sounds wrong to me. At least maths seems to need the idea of the 'correct' answer. If, however, maths is a huge pattern, there is no correctness, just the pattern. We can be wrong, but maths can't be wrong. Ah, I see…! |
4241 | If there are infinite numbers and finite concrete objects, this implies that numbers are abstract objects [Lowe] |
Full Idea: The Peano postulates imply an infinity of numbers, but there are probably not infinitely many concrete objects in existence, so natural numbers must be abstract objects. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.375) | |
A reaction: Presumably they are abstract objects even if they aren't universals. 'Abstract' is an essential term in our ontological vocabulary to cover such cases. Perhaps possible concrete objects are infinite. |
4239 | Nominalists deny abstract objects, because we can have no reason to believe in their existence [Lowe] |
Full Idea: Nominalists tend to deny the existence of abstract objects since, given their purported nature (non-causal), we can have no reason to believe in their existence. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.372) | |
A reaction: A good point. Aristotle worried about the causal inadequacy of the Forms. My mind can conceive of a 'thing' with no causal powers, just sitting there. |
4202 | Change can be of composition (the component parts), or quality (properties), or substance [Lowe] |
Full Idea: There seem to be three kinds of change: compositional change (of component parts), qualitative change (of properties), or substantial change (when underlying essence begins or ceases). | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.59) | |
A reaction: Notice this gives 'components' a more prominent ontological status than usual. Is this computer a component of my study? |
4201 | Four theories of qualitative change are 'a is F now', or 'a is F-at-t', or 'a-at-t is F', or 'a is-at-t F' [Lowe, by PG] |
Full Idea: Qualitative change is seen as either (i) 'Presentism' - 'a is F now', or (ii) 'relational properties' - 'a is F-at-t', or (iii) 'temporal parts' - 'a-at-t is F', or (iv) 'adverbial' - 'a is-a-t F'. | |
From: report of E.J. Lowe (A Survey of Metaphysics [2002], p.44) by PG - Db (ideas) | |
A reaction: The traditional view would let a stay the same over time, and change its property (ii). Lewis favours (iii). My suspicion is that thinking collapses if you abandon the tradtional view. |
4219 | Numerically distinct events of the same kind (like two battles) can coincide in space and time [Lowe] |
Full Idea: Numerically distinct events of the same kind (like two battles) can plausible coincide in space and time. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.225) | |
A reaction: This is certainly discouraging for anyone who wanted to make events ontologically basic. Physicalist need to be able to individuate events in a reductive way. |
4221 | Maybe modern physics requires an event-ontology, rather than a thing-ontology [Lowe] |
Full Idea: It is sometimes said that modern physics requires us to espouse an event-ontology, rather than a thing-ontology. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.233) | |
A reaction: It has to be a mistake to build our philosophical ontology on current physics, because even the physicists say they don't understand the latter very well. |
4220 | 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. |
4225 | 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. |
11151 | An object is dependent if its essence prevents it from existing without some other object [Fine,K] |
Full Idea: One object depends upon another (in one sense of the term) if its essence prevents it from existing without the other object. | |
From: Kit Fine (Essence and Modality [1994], p. 2) | |
A reaction: I take the interest of this to be that essences are usually thought to be intrinsic, but this seems to involve the object in necessary external relations. |
4196 | The main categories of existence are either universal and particular, or abstract and concrete [Lowe] |
Full Idea: Some metaphysicians think the fundamental categories of existence are universals and particulars, while other prefer the division between abstract and concrete. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.15) | |
A reaction: Interestingly, in trying to choose between these, it is tempting to think about the capacities of the brain. Which is the cart and which is the horse? |
4234 | Trope theory says blueness is a real feature of objects, but not the same as an identical blue found elsewhere [Lowe] |
Full Idea: The trope theorist holds that the blueness of a blue chair really exists as much as the chair, but is not identified with the blueness of anything else, even if it resembles it exactly. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.361) | |
A reaction: You are left with explaining how 'resemblance' works if you cannot spot some 'thing' in common. It is an inviting idea, though, because it avoids the ontological baggage of universals. |
4235 | Maybe a cushion is just a bundle of tropes, such as roundness, blueness and softness [Lowe] |
Full Idea: The trope theorist says that a cushion is just a 'bundle' of tropes, such as roundness, blueness and softness. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.362) | |
A reaction: Certainly if you dispense with the idea of substance (which is clearly bad science even if it is good metaphysics), something like this is what remains of a cushion, though it sounds more epistemological than ontological. Only philosophers care about this |
4236 | Tropes seem to be abstract entities, because they can't exist alone, but must come in bundles [Lowe] |
Full Idea: Tropes seem to be abstract entities because, unlike concrete entities, they are ontologically dependent; ..there are no 'free' tropes, and they must always be bundled with other appropriate tropes to exist. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.367) | |
A reaction: Only a Platonist would think that a universal property could 'exist alone'. I presume Aristotle thought universals were real, though bound up with substances. |
4197 | The category of universals can be sub-divided into properties and relations [Lowe] |
Full Idea: One might want to divide the category of 'universals' into two sub-categories of properties and relations. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.15) | |
A reaction: This means a Platonic form like 'horse' ends up as a cluster of properties and relations. Is a substance not also a universal? |
4232 | Nominalists believe that only particulars exist [Lowe] |
Full Idea: Nominalists believe that only particulars exist. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.352) | |
A reaction: A neat definition. Hence they deny universals. I suspect that nominalism is incoherent. Rational thought seems easy to create with universals, impossible with just particulars. Robotics is nominalist, which is why it will fail. |
4205 | 'Is non-self-exemplifying' is a predicate which cannot denote a property (as it would be a contradiction) [Lowe] |
Full Idea: Not every meaningful predicate expresses an existing property; thus 'is non-self-exemplifying' cannot refer to a property, because the property would contradict the predicate. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.100) | |
A reaction: Needs thought. The example is based on Russell's so-called Barber's Paradox. If it can't be a property, can it be a predicate? |
4233 | If 'blueness' is a set of particulars, there is danger of circularity, or using universals, in identifying the set [Lowe] |
Full Idea: If sets are particulars, a nominalist may say that 'blueness' is a set of particulars, but which set? If the particulars 'are blue' this threatens circularity - though resemblance is usually appealed to to avoid this. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.355) | |
A reaction: This supports my suspicion that nominalism is superficially attractive and 'scientific', but when you dig deep into it the theory won't get off the ground without universals. |
4206 | Conventionalists see the world as an amorphous lump without identities, but are we part of the lump? [Lowe] |
Full Idea: For the conventionalist the world is doomed to merge into an amorphous lump with no real individuality or differentiation, ..but we can hardly make our own identity in the world in the way we are supposed to conventionally create identity for objects. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.113) | |
A reaction: Very nice argument! We need to 'cut nature at the joints' (Plato), and one joint is screamingly obvious - that between observer and world. You could try denying this, but it would be a bizarre view. |
4204 | Statues can't survive much change to their shape, unlike lumps of bronze, which must retain material [Lowe] |
Full Idea: A statue is a kind of object which cannot survive much change to its shape, unlike a lump of bronze, which cannot survive any change to its material composition. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.70) | |
A reaction: Also the statue could survive being hollowed out, changing its material composition. Hence a statue is not just a lump of bronze, but we knew that. |
11152 | Essences are either taken as real definitions, or as necessary properties [Fine,K] |
Full Idea: Essence has been conceived either on the model of definition, involving the 'real' as opposed to 'nominal' definitions, or it is elucidated in modal terms, located in de re cases of modal attributions (an object being necessarily a certain way). | |
From: Kit Fine (Essence and Modality [1994], p. 2) | |
A reaction: [compressed] Fine sets out to defend the definitional view, which derives from Aristotle, his line being that necessity depends on essence, and so cannot be used to define it. I think I agree. |
11161 | Essentially having a property is naturally expressed as 'the property it must have to be what it is' [Fine,K] |
Full Idea: We have an informal way of saying an object essentially has a property, as 'the object must have the property if it is to be the object that it is', and this form of words manages to convey what we wish to convey. | |
From: Kit Fine (Essence and Modality [1994], p. 4) | |
A reaction: The importance of this claim is that it makes no mention of 'necessity'. Fine's view is plausible, but hard to evaluate once he has said. We seem to then divide an object's properties into identity properties, causal properties and peripheral properties. |
11160 | Simple modal essentialism refers to necessary properties of an object [Fine,K] |
Full Idea: The simplest form of the modal account takes an object to have a property essentially just in case it is necessary that the object has the property. | |
From: Kit Fine (Essence and Modality [1994], p. 3) | |
A reaction: Fine wants to reverse the account, explaining necessities in terms of prior essences. |
11158 | Essentialist claims can be formulated more clearly with quantified modal logic [Fine,K] |
Full Idea: With the advent of quantified modal logic, philosophers have been in a better position to formulate essentialist claims. | |
From: Kit Fine (Essence and Modality [1994], p. 3) | |
A reaction: A nice illustration of the role which logic plays in modern analytic philosophy. It is not an unreasonable assumption that we will understand a theoretical problem more clearly if we can articulate it more accurately. |
11167 | Metaphysical necessity is a special case of essence, not vice versa [Fine,K] |
Full Idea: Far from viewing essence as a special case of metaphysical necessity, we should view metaphysical necessity as a special case of essence. | |
From: Kit Fine (Essence and Modality [1994], p. 9) | |
A reaction: This strikes me as one of the most powerful proposals in modern philosophy (even if it is a reiteration of Aristotle!). |
16537 | Essence as necessary properties produces a profusion of essential properties [Fine,K, by Lowe] |
Full Idea: If an essence is a sum of essential properties (had in all possible worlds where it exists), Fine points out that it seems grossly to overgenerate essential properties ('S is either a man or a mouse', or 'S is such that 2+2=4'). | |
From: report of Kit Fine (Essence and Modality [1994]) by E.J. Lowe - What is the Source of Knowledge of Modal Truths? 6 | |
A reaction: To me this is the sort of mess you get into when you accept that 'being such that p' is a property. Defenders of the modal approach always have to eliminate 'trivial' properties from essences, but non-trivial is a defining feature of an essence. |
11163 | The nature of singleton Socrates has him as a member, but not vice versa [Fine,K] |
Full Idea: Can we not recognise a sense of 'what an object is', according to which it lies in the nature of a singleton to have Socrates as a member, even though it does not lie in the nature of Socrates to belong to the singleton? | |
From: Kit Fine (Essence and Modality [1994], p. 5) | |
A reaction: Important and persuasive. It echoes the example in Idea 11162, that the necessary relation is not part of the essence. Socrates is necessarily in {Socrates}, but that is because of the set, not because of Socrates. Essences causes necessities. |
11164 | It is not part of the essence of Socrates that a huge array of necessary truths should hold [Fine,K] |
Full Idea: Necessarily any necessary truth will hold if Socrates exists. But it is no part of Socrates' essence that there be infinitely many prime numbers, ..or that objects like the Eiffel Tower have their own necessary essence. | |
From: Kit Fine (Essence and Modality [1994], p. 5-6) | |
A reaction: This and the 'singleton Socrates' example (Idea 11165) are the twin prongs of Fine's attack on the modal account of essentialism. I think they constitute one of the best single pages in the whole of recent philosophy. Bravo. |
10935 | An essential property of something must be bound up with what it is to be that thing [Fine,K, by Rami] |
Full Idea: Fine's view is that the notion of an essential property of a thing should be bound up with the notion of what it is to be that thing (unlike, for example, Socrates being such that there are infinitely many primes). | |
From: report of Kit Fine (Essence and Modality [1994]) by Adolph Rami - Essential vs Accidental Properties §2 | |
A reaction: I would think that Fine is so obviously right that it was hardly worth saying, but philosophers are a funny lot, and are quite likely to claim that features of prime numbers are part of the essence of a long-dead philosopher. |
10936 | Essential properties are part of an object's 'definition' [Fine,K, by Rami] |
Full Idea: According to Fine's definitional characterization of essential properties, they are those of an object's properties that are part of the object's 'definition'. | |
From: report of Kit Fine (Essence and Modality [1994]) by Adolph Rami - Essential vs Accidental Properties §2 | |
A reaction: This demands not just an account of what a definition is, but also the notion that there is only one fixed and correct definition (since the object presumably only has one essence) - but there seems to be something relative about a good definition. |
4200 | If old parts are stored and then appropriated, they are no longer part of the original (which is the renovated ship). [Lowe] |
Full Idea: The parts of a ship in a warehouse belong to no ship at all, ..and once they are appropriated by another ship they cease to be parts of the original, ..so it seems that the renovated ship (not the reconstruction) is identified with the original. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.31) | |
A reaction: The parts in the warehouse could belong to the original (they might even labelled), but assigning them to a new ship does indeed look like a crucial break in the continuity. |
4198 | If 5% replacement preserves a ship, we can replace 4% and 4% again, and still retain the ship [Lowe] |
Full Idea: If we say that up to 5% of a ship's parts can be replaced without the ship ceasing to exist, we could replace 4% and then 4% again, and it would retain its identity, if identity is transitive. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.26) | |
A reaction: One suspected that all attempts at precision with the ship of Theseus were doomed, but this nicely demonstrates it. |
4199 | A renovation or a reconstruction of an original ship would be accepted, as long as the other one didn't exist [Lowe] |
Full Idea: If a ship is renovated without reconstruction of original parts, we happily identify the renovation with the original; if there was a reconstruction without the renovated version, we would identify the reconstruction with the original. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.27) | |
A reaction: This really shakes our belief in identity as a natural rather than mental phenomenon. The existence of clones undermines our normal idea of personal identity. |
11165 | If Socrates lacks necessary existence, then his nature cannot require his parents' existence [Fine,K] |
Full Idea: If there is nothing in the nature of Socrates which demands that he exists, then presumably there is nothing in the nature of Socrates which demands that his parents exist. | |
From: Kit Fine (Essence and Modality [1994], p. 6) | |
A reaction: This sounds conclusive to me, against any claim that Socrates necessarily had those parents, if the claim is based on the identity or esssence of Socrates. |
4203 | Identity of Indiscernibles (same properties, same thing) ) is not Leibniz's Law (same thing, same properties) [Lowe] |
Full Idea: The Identity of Indiscernibles (no two objects can possess exactly the same properties) is not the same as Leibniz's Law (what is true of a thing is true of what is identical with that thing). | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.62) | |
A reaction: Two things can't be the same because we can't discern the difference, which may be our inadequacy. But if they actually have identical properties, it is hard to see how they could be different. A universe with just two perfect spheres is couterexample. |
4195 | It is impossible to reach a valid false conclusion from true premises, so reason itself depends on possibility [Lowe] |
Full Idea: Reasoning itself depends upon a grasp of possibilities, because a valid argument is one in which it is not possible for the conclusion to be false if the premises are true. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.11) | |
A reaction: A very valuable corrective to my pessimistic view of philosophers' attempts to understand metaphysical necessity. But if we can only grasp natural necessity, then all reason is naturalistic. |
11166 | The subject of a proposition need not be the source of its necessity [Fine,K] |
Full Idea: We naturally suppose, if a subject-predicate proposition is necessary, that the subject of the proposition is the source of the necessity. But that singleton 2 contains 2 is necessary, whether the number or the set is the subject of the proposition. | |
From: Kit Fine (Essence and Modality [1994], p. 9) | |
A reaction: A very nice addition to his general attack on the idea that essence should be accounted for in terms of his necessity. He asks a beautifully simple question: for each necessity that we accept, what is the source of that necessity? |
11169 | Conceptual necessities rest on the nature of all concepts [Fine,K] |
Full Idea: Conceptual (and logical) necessities can be taken to be the propositions which are true in virtue of the nature of all concepts (or just the logical concepts). | |
From: Kit Fine (Essence and Modality [1994], p. 9-10) | |
A reaction: The idea that something might be true simply because of the nature of a concept sounds good, and a slightly better formulation than traditional accounts of analytic truth. |
11162 | Socrates is necessarily distinct from the Eiffel Tower, but that is not part of his essence [Fine,K] |
Full Idea: It is necessary that Socrates and the Eiffel Tower be distinct. But it is not essential to Socrates that he be distinct from the Tower, for there is nothing in his nature which connects him in any special way to it. | |
From: Kit Fine (Essence and Modality [1994], p. 5) | |
A reaction: I find this simple argument very persuasive in separating out necessary facts about an object from the essence of that object. |
11168 | Metaphysical necessities are true in virtue of the nature of all objects [Fine,K] |
Full Idea: The metaphysically necessary truths can be identified with the propositions which are true in virtue of the nature of all objects whatever. | |
From: Kit Fine (Essence and Modality [1994], p. 9) | |
A reaction: This is part of Fine's proposal that necessities are derived from the essences or natures of things, which view I find very congenial. |
4207 | We might eliminate 'possible' and 'necessary' in favour of quantification over possible worlds [Lowe] |
Full Idea: It may be possible to eliminate the modal operators (in English, 'is possible' and 'is necessary') in favour of quantifier expressions with variables ranging over possible worlds. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.121) | |
A reaction: Hence 'necessary' becomes 'exists/is true in all possible worlds'. Deep problems, but at least we must show that referring to 'possible' worlds isn't a circular explanation of 'is possible'. |
4223 | Unfalsifiability may be a failure in an empirical theory, but it is a virtue in metaphysics [Lowe] |
Full Idea: Although unfalsifiability is probably a defect in scientific hypothesis, because it is deprived of empirical content, it seems rather to be a virtue in a metaphysical hypothesis. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.241) | |
A reaction: Presumably nothing could ever be found to count against a necessary truth. A nice point. 'Find me an instance where 2+2 is not 4'. |
4193 | The behaviour of persons and social groups seems to need rational rather than causal explanation [Lowe] |
Full Idea: There are some entities which exist in time and space (such as persons or social groups) of which the behaviour seems to be subject to rational rather than merely causal explanation. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.2) | |
A reaction: This begs of the question of whether 'rational' can be reduced to causal. We can't manage causal explanations of the very complex, so we use broad-brush second-best explanations? |
4238 | The centre of mass of the solar system is a non-causal abstract object, despite having a location [Lowe] |
Full Idea: The centre of mass of the solar system seems to lack causal powers, and so is an abstract object, even though it has a location and movement. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
A reaction: Nice example, with rich ramifications. Abstraction is deeply tied into our understanding of the physical world, and our concept of identity. |
4237 | Concrete and abstract objects are distinct because the former have causal powers and relations [Lowe] |
Full Idea: Concrete objects possess causal powers and relations, but abstract objects are incapable of having causal powers or relations. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.368) | |
A reaction: Is this an observation or a definition? One might claim that an abstraction (such as a political ideal) can acquire causal power through a conscious mnd. |
11170 | Analytic truth may only be true in virtue of the meanings of certain terms [Fine,K] |
Full Idea: Just as a necessary truth may be true in virtue of the identity of certain objects as opposed to others, so an analytic truth may be true in virtue of the meanings of certain terms as opposed to others (such as 'bachelor' rather than 'unmarried'). | |
From: Kit Fine (Essence and Modality [1994], p.10) | |
A reaction: This is a beautifully simple observation, that the necessity of 'bachelors are unmarried men' derives from part of the proposition, not from the whole of it. So what is it about the part that generates the apparent necessity? The nature of the concept! |
11172 | The meaning of 'bachelor' is irrelevant to the meaning of 'unmarried man' [Fine,K] |
Full Idea: Strictly speaking it is irrelevant to the meaning of 'bachelor' that the phrase 'unmarried man' means what it does. | |
From: Kit Fine (Essence and Modality [1994], p.13) | |
A reaction: His point is that the necessary truth here derives from the meaning of 'bachelor', and not from the meaning of 'unmarried man'. But is also true that 'unmarried man' means 'bachelor' (for those familiar with the latter, but not the former). |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
4210 | If the concept of a cause says it precedes its effect, that rules out backward causation by definition [Lowe] |
Full Idea: You can't include in your concept of causation a clause stipulating that the cause occurred earlier than the effect, because that would rule out backward causation by definition. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.176) | |
A reaction: It may, though, be the case that backward causes can't occur, and time is essential to causes. The problem is our inability to know this for sure. |
4215 | It seems proper to say that only substances (rather than events) have causal powers [Lowe] |
Full Idea: It seems proper to say that events of themselves possess no causal powers; only persisting objects (individual substances) possess causal powers. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.211) | |
A reaction: This requires events to be reduced to substances, which invites Aristotle's question of where the movement comes from. In physcis, 'energy' is the key concept. |
4209 | The theories of fact causation and event causation are both worth serious consideration [Lowe] |
Full Idea: The theories of fact causation and event causation are both worth serious consideration. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.173) | |
A reaction: This is slippery ground because both 'facts' and 'events' have uncertain ontological status, and seem partly conventional rather than natural. Events might be natural surges or transformations of energy? |
4211 | Causal overdetermination is either actual overdetermination, or pre-emption, or the fail-safe case [Lowe] |
Full Idea: In causation there is 'overdetermination' (c and d occurred, and were both sufficient for e), 'pre-emption' (c and d occurred, and d would have stepped in if c hadn't), or 'fail-safe' (if c hadn't occurred, d would have occurred and done it). | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.179) | |
A reaction: Two safety nets together, two safety nets spaced apart, or a second net which pops in if the first breaks. Nice distinctions. |
4213 | Causation may be instances of laws (seen either as constant conjunctions, or as necessities) [Lowe] |
Full Idea: Causation relations between events may an instance of a causal law, with laws either interpreted as constant conjunctions (Hume), or as necessitation among universals (Armstrong). | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.190) | |
A reaction: Hume's version is a thin idea of a law, but we can dream about the metaphysical status of laws, even if we don't know much about them. Lowe says a cause without a law is perfectly intelligible. |
4212 | Hume showed that causation could at most be natural necessity, never metaphysical necessity [Lowe] |
Full Idea: One thing Hume has taught us is that the necessity which causation involves is at most 'natural' or 'physical' necessity, not metaphysical necessity. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.182) | |
A reaction: Given Hume's epistemological scepticism, I don't think he would claim to have shown such a thing. See G.Strawson's book. Metaphysical necessity of causation is possible, but unknowable. |
14581 | The normative view says laws show the natural behaviour of natural kind members [Lowe, by Mumford/Anjum] |
Full Idea: For Lowe law statements are in a sense about what 'ought' to be the case. The 'ought' is not an explicitly moral or anthropomorphic one but instead tells us what is the natural behaviour of kind members. | |
From: report of E.J. Lowe (A Survey of Metaphysics [2002]) by S.Mumford/R.Lill Anjum - Getting Causes from Powers 8.6 | |
A reaction: This is the 'normative' view of laws (as opposed to the intentional, dispositional, or regularity accounts). They cite Lowe 1989 Ch.8. The obvious immediate problem is things which evolved for one purpose and end up being used for another. |
4208 | 'If he wasn't born he wouldn't have died' doesn't mean birth causes death, so causation isn't counterfactual [Lowe] |
Full Idea: Counterfactual analyses of event causation don't seem to work, because 'if Napoleon hadn't been born he wouldn't have died' is true, but doesn't mean his birth caused his death. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.161) | |
A reaction: Nice counterexample, which looks pretty conclusive. Birth makes death possible; it creates the necessary conditions within which it can be caused. |
4224 | If motion is change of distance between objects, it involves no intrinsic change in the objects [Lowe] |
Full Idea: If motion just is change of distance between two objects, it does not involve any kind of intrinsic change in the objects in question. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.242) | |
A reaction: It sound respectably relativistic, but I doubt the definition. x is moving relative to y, then y attains x's velocity, so x ceases to move? Maybe. |
4227 | Surfaces, lines and points are not, strictly speaking, parts of space, but 'limits', which are abstract [Lowe] |
Full Idea: Surfaces, lines and points are not, strictly speaking, parts of space at all, but just 'limits' of certain kinds, and as such 'abstract' entities. | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.254) | |
A reaction: This is fairly crucial when dealing with Zeno's paradoxes. How many points in a line? How long to get through a point? |
4228 | If space is entirely relational, what makes a boundary, or a place unoccupied by physical objects? [Lowe] |
Full Idea: If space does not exist at all, but is only relations between objects, what could one possibly mean by saying that there is a place which is unoccupied by any material object? And what determines whether space is bounded? | |
From: E.J. Lowe (A Survey of Metaphysics [2002], p.264) | |
A reaction: Correct. People who assert that space is only relational have been misled by what we can know about space, not what it is. |
