1. Philosophy / E. Nature of Metaphysics / 4. Metaphysics as Science
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.
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
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?
1. Philosophy / G. Scientific Philosophy / 2. Positivism
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.
2. Reason / B. Laws of Thought / 6. Ockham's Razor
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.
3. Truth / A. Truth Problems / 5. Truth Bearers
In its primary and formal sense, 'true' applies to propositions, not beliefs [Russell]
     Full Idea: We call a belief true when it is belief in a true proposition, ..but it is to propositions that the primary formal meanings of 'truth' and 'falsehood' apply.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §IV)
     A reaction: I think this is wrong. A proposition such as 'it is raining' would need a date-and-time stamp to be a candidate for truth, and an indexical statement such as 'I am ill' would need to be asserted by a person. Of course, books can contain unread truths.
3. Truth / B. Truthmakers / 1. For Truthmakers
The truth or falsehood of a belief depends upon a fact to which the belief 'refers' [Russell]
     Full Idea: I take it as evident that the truth or falsehood of a belief depends upon a fact to which the belief 'refers'.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], p.285)
     A reaction: A nice bold commitment to a controversial idea. The traditional objection is to ask how you are going to formulate the 'facts' except in terms of more beliefs, so you ending up comparing beliefs. Facts are a metaphysical commitment, not an acquaintance.
3. Truth / C. Correspondence Truth / 1. Correspondence Truth
Propositions of existence, generalities, disjunctions and hypotheticals make correspondence tricky [Russell]
     Full Idea: The correspondence of proposition and fact grows increasingly complicated as we pass to more complicated types of propositions: existence-propositions, general propositions, disjunctive and hypothetical propositions, and so on.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §IV)
     A reaction: An important point. Truth must not just work for 'it is raining', but also for maths, logic, tautologies, laws etc. This is why so many modern philosophers have retreated to deflationary and minimal accounts of truth, which will cover all cases.
5. Theory of Logic / L. Paradox / 4. Paradoxes in Logic / a. Achilles paradox
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?
6. Mathematics / A. Nature of Mathematics / 1. Mathematics
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…!
6. Mathematics / C. Sources of Mathematics / 1. Mathematical Platonism / a. For mathematical platonism
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.
7. Existence / A. Nature of Existence / 4. Abstract Existence
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.
7. Existence / B. Change in Existence / 1. Nature of Change
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?
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.
7. Existence / B. Change in Existence / 4. Events / a. Nature of events
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.
7. Existence / B. Change in Existence / 4. Events / b. Events as primitive
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.
7. Existence / B. Change in Existence / 4. Events / c. Reduction of events
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.
7. Existence / E. Categories / 3. Proposed Categories
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?
8. Modes of Existence / B. Properties / 13. Tropes / a. Nature of tropes
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.
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
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.
8. Modes of Existence / D. Universals / 1. Universals
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?
8. Modes of Existence / E. Nominalism / 1. Nominalism / b. Nominalism about universals
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.
8. Modes of Existence / E. Nominalism / 3. Predicate Nominalism
'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?
8. Modes of Existence / E. Nominalism / 5. Class Nominalism
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.
9. Objects / A. Existence of Objects / 6. Nihilism about Objects
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.
9. Objects / B. Unity of Objects / 3. Unity Problems / c. Statue and clay
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.
9. Objects / E. Objects over Time / 9. Ship of Theseus
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.
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.
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.
9. Objects / F. Identity among Objects / 7. Indiscernible Objects
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.
10. Modality / B. Possibility / 1. Possibility
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.
10. Modality / E. Possible worlds / 1. Possible Worlds / a. Possible worlds
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'.
11. Knowledge Aims / A. Knowledge / 4. Belief / b. Elements of beliefs
The three questions about belief are its contents, its success, and its character [Russell]
     Full Idea: There are three issues about belief: 1) the content which is believed, 2) the relation of the content to its 'objective' - the fact which makes it true or false, and 3) the element which is belief, as opposed to consideration or doubt or desire.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §III)
     A reaction: The correct answers to the questions (trust me) are that propositions are the contents, the relation aimed at is truth, which is a 'metaphysical ideal' of correspondence to facts, and belief itself is an indefinable feeling. See Hume, Idea 2208.
14. Science / A. Basis of Science / 6. Falsification
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'.
14. Science / D. Explanation / 1. Explanation / d. Explaining people
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?
15. Nature of Minds / B. Features of Minds / 5. Qualia / c. Explaining qualia
Obviously there can't be a functional anaylsis of qualia if they are defined by intrinsic properties [Dennett]
     Full Idea: If you define qualia as intrinsic properties of experiences considered in isolation from all their causes and effects, logically independent of all dispositional properties, then they are logically guaranteed to elude all broad functional analysis.
     From: Daniel C. Dennett (Sweet Dreams [2005], Ch.8)
     A reaction: This is a good point - it seems daft to reify qualia and imagine them dangling in mid-air with all their vibrant qualities - but that is a long way from saying there is nothing more to qualia than functional roles. Functions must be exlained too.
16. Persons / E. Rejecting the Self / 4. Denial of the Self
The work done by the 'homunculus in the theatre' must be spread amongst non-conscious agencies [Dennett]
     Full Idea: All the work done by the imagined homunculus in the Cartesian Theater must be distributed among various lesser agencies in the brain, none of which is conscious.
     From: Daniel C. Dennett (Sweet Dreams [2005], Ch.3)
     A reaction: Dennett's account crucially depends on consciousness being much more fragmentary than most philosophers claim it to be. It is actually full of joints, which can come apart. He may be right.
17. Mind and Body / B. Behaviourism / 4. Behaviourism Critique
If we object to all data which is 'introspective' we will cease to believe in toothaches [Russell]
     Full Idea: If privacy is the main objection to introspective data, we shall have to include among such data all sensations; a toothache, for example, is essentially private; a dentist may see the bad condition of your tooth, but does not feel your ache.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §II)
     A reaction: Russell was perhaps the first to see why eliminative behaviourism is a non-starter as a theory of mind. Mental states are clearly a cause of behaviour, so they can't be the same thing. We might 'eliminate' mental states by reducing them, though.
17. Mind and Body / D. Property Dualism / 3. Property Dualism
There are distinct sets of psychological and physical causal laws [Russell]
     Full Idea: There do seem to be psychological and physical causal laws which are distinct from each other.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §II)
     A reaction: This sounds like the essence of 'property dualism'. Reductive physicalists (like myself) say there is no distinction. Davidson, usually considered a property dualist, claims there are no psycho-physical laws. Russell notes that reduction may be possible.
17. Mind and Body / E. Mind as Physical / 2. Reduction of Mind
Intelligent agents are composed of nested homunculi, of decreasing intelligence, ending in machines [Dennett]
     Full Idea: As long as your homunculi are more stupid and ignorant than the intelligent agent they compose, the nesting of homunculi within homunculi can be finite, bottoming out, eventually, with agents so unimpressive they can be replaced by machines.
     From: Daniel C. Dennett (Sweet Dreams [2005], Ch.6)
     A reaction: [Dennett first proposed this in 'Brainstorms' 1978]. This view was developed well by Lycan. I rate it as one of the most illuminating ideas in the modern philosophy of mind. All complex systems (like aeroplanes) have this structure.
17. Mind and Body / E. Mind as Physical / 3. Eliminativism
I don't deny consciousness; it just isn't what people think it is [Dennett]
     Full Idea: I don't maintain, of course, that human consciousness does not exist; I maintain that it is not what people often think it is.
     From: Daniel C. Dennett (Sweet Dreams [2005], Ch.3)
     A reaction: I consider Dennett to be as near as you can get to an eliminativist, but he is not stupid. As far as I can see, the modern philosopher's bogey-man, the true total eliminativist, simply doesn't exist. Eliminativists usually deny propositional attitudes.
18. Thought / B. Mechanics of Thought / 6. Artificial Thought / a. Artificial Intelligence
What matters about neuro-science is the discovery of the functional role of the chemistry [Dennett]
     Full Idea: Neuro-science matters because - and only because - we have discovered that the many different neuromodulators and other chemical messengers that diffuse throughout the brain have functional roles that make important differences.
     From: Daniel C. Dennett (Sweet Dreams [2005], Ch.1)
     A reaction: I agree with Dennett that this is the true ground for pessimism about spectacular breakthroughs in artificial intelligence, rather than abstract concerns about irreducible features of the mind like 'qualia' and 'rationality'.
18. Thought / E. Abstraction / 5. Abstracta by Negation
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.
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.
19. Language / D. Propositions / 1. Propositions
Our important beliefs all, if put into words, take the form of propositions [Russell]
     Full Idea: The important beliefs, even if they are not the only ones, are those which, if rendered into explicit words, take the form of a proposition.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §III)
     A reaction: This assertion is close to the heart of the twentieth century linking of ontology and epistemology to language. It is open to challenges. Why is non-propositional belief unimportant? Do dogs have important beliefs? Can propositions exist non-verbally?
A proposition expressed in words is a 'word-proposition', and one of images an 'image-proposition' [Russell]
     Full Idea: I shall distinguish a proposition expressed in words as a 'word-proposition', and one consisting of images as an 'image-proposition'.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], §III)
     A reaction: This, I think, is good, though it raises the question of what exactly an 'image' is when it is non-visual, as when a dog believes its owner called. This distinction prevents us from regarding all knowledge and ontology as verbal in form.
A proposition is what we believe when we believe truly or falsely [Russell]
     Full Idea: A proposition may be defined as: what we believe when we believe truly or falsely.
     From: Bertrand Russell (On Propositions: What they are, and Meaning [1919], p.285)
     A reaction: If we define belief as 'commitment to truth', Russell's last six words become redundant. "Propositions are the contents of beliefs", it being beliefs which are candidates for truth, not propositions. (Russell agrees, on p.308!)
26. Natural Theory / C. Causation / 5. Direction of causation
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.
26. Natural Theory / C. Causation / 8. Particular Causation / b. Causal relata
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.
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?
26. Natural Theory / C. Causation / 8. Particular Causation / c. Conditions of causation
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.
26. Natural Theory / C. Causation / 9. General Causation / b. Nomological causation
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.
26. Natural Theory / C. Causation / 9. General Causation / d. Causal necessity
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.
26. Natural Theory / D. Laws of Nature / 1. Laws of Nature
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.
26. Natural Theory / D. Laws of Nature / 9. Counterfactual Claims
'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.
27. Natural Reality / A. Classical Physics / 1. Mechanics / a. Explaining movement
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.
27. Natural Reality / C. Space / 3. Points in Space
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?
27. Natural Reality / C. Space / 5. Relational Space
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.
