1. Philosophy / A. Wisdom / 2. Wise People
The best philosophers I know are the best people I know [Heil]
     Full Idea: Philosophers are not invariably the best people, but the best philosophers I know are the best people I know.
     From: John Heil (The Universe as We Find It [2012], Pref)
     A reaction: How very nicely expressed. I have often thought the same about lovers of literature, but been horribly disappointed by some of them. On the whole I have found philosophy-lovers to be slightly superior to literature-lovers!
1. Philosophy / D. Nature of Philosophy / 7. Despair over Philosophy
Using a technical vocabulary actually prevents discussion of the presuppositions [Heil]
     Full Idea: Sharing a technical vocabulary is to share a tidy collection of assumptions. Reliance on that vocabulary serves to foreclose discussion of those assumptions.
     From: John Heil (The Universe as We Find It [2012], Pref)
     A reaction: Love it! I am endlessly frustrated by papers that launch into a discussion using a terminology that is riddled with dubious prior assumptions. And that includes common terms like 'property', as well as obscure neologisms.
1. Philosophy / E. Nature of Metaphysics / 2. Possibility of Metaphysics
Questions of explanation should not be confused with metaphyics [Heil]
     Full Idea: There is an unfortunate tendency to conflate epistemological issues bearing on explanation with issues in metaphysics.
     From: John Heil (The Universe as We Find It [2012], 01.2)
     A reaction: This is where Heil and I part ways. I just don't believe in the utterly pure metaphysics which he thinks we can do. Our drive to explain moulds our vision of reality, say I.
1. Philosophy / E. Nature of Metaphysics / 3. Metaphysical Systems
Without abstraction we couldn't think systematically [Heil]
     Full Idea: A capacity for abstraction is central to our capacity to think about the universe systematically.
     From: John Heil (The Universe as We Find It [2012], 09.7)
     A reaction: This strikes me as obvious. We pick out the similarities, and then discuss them, as separate from their bearers. We explain why things have features in common. Some would just say systematic thinking needs universals, but that's less good.
2. Reason / A. Nature of Reason / 3. Pure Reason
Reasonings have a natural ordering in God's understanding, but only a temporal order in ours [Leibniz]
     Full Idea: All reasonings are eminent in God, and they preserve an order among themselves in his understanding as well as in ours; but for him this is just an order and a priority of nature, whereas for us there is a priority of time.
     From: Gottfried Leibniz (The Theodicy [1710], p.192), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.III
     A reaction: This view is found in Frege, and seems to be the hallmark of rationalist philosophy. There is an apriori assumption that reality has a rational order, so that pure reason is a tool for grasping it. Lewis's 'mosaic' of experiences has no order.
2. Reason / B. Laws of Thought / 6. Ockham's Razor
Ockham's Razor is the principle that we need reasons to believe in entities [Mellor/Oliver]
     Full Idea: Ockham's Razor is the principle that we need reasons to believe in entities.
     From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §9)
     A reaction: This presumably follows from an assumption that all beliefs need reasons, but is that the case? The Principle of Sufficient Reason precedes Ockham's Razor.
3. Truth / A. Truth Problems / 4. Uses of Truth
Truth relates truthbearers to truthmakers [Heil]
     Full Idea: Truth is a relation between a truthbearer and a truthmaker.
     From: John Heil (The Universe as We Find It [2012], 08.02)
     A reaction: This implies that all truths have truthmakers, which is fairly controversial. Heil himself denies it!
3. Truth / B. Truthmakers / 1. For Truthmakers
Philosophers of the past took the truthmaking idea for granted [Heil]
     Full Idea: For millenia, philosophers operated with an implicit conception of truthmaking, a conception that remained unarticulated only because it was part of the very fabric of philosophy.
     From: John Heil (The Universe as We Find It [2012], 07.2)
     A reaction: Presumably it is an advance that we have brought it out into the open, and subjected it to critical study. Does Heil want us to return to it being unquestioned? I like truthmaking, but that can't be right.
3. Truth / B. Truthmakers / 3. Truthmaker Maximalism
Not all truths need truthmakers - mathematics and logic seem to be just true [Heil]
     Full Idea: I do not subscribe to the thesis that every truth requires a truthmaker. Mathematical truths and truths of logic are compatible with any way the universe could be.
     From: John Heil (The Universe as We Find It [2012], 01.5)
     A reaction: He makes that sound like a knock-down argument, but I'm not convinced. I see logic and mathematics as growing out of nature, though that is a very unfashionable view. I'm almost ashamed of it. But I'm not giving it up. See Carrie Jenkins.
6. Mathematics / A. Nature of Mathematics / 5. The Infinite / a. The Infinite
Infinite numbers are qualitatively different - they are not just very large numbers [Heil]
     Full Idea: It is a mistake to think of an infinite number as a very large number. Infinite numbers differ qualitatively from finite numbers.
     From: John Heil (The Universe as We Find It [2012], 03.5)
     A reaction: He cites Dedekind's idea that a proper subset of an infinite number can match one-one with the number. Respectable numbers don't behave in this disgraceful fashion. This should be on the wall of every seminar on philosophy of mathematics.
6. Mathematics / B. Foundations for Mathematics / 7. Mathematical Structuralism / e. Structuralism critique
How could structures be mathematical truthmakers? Maths is just true, without truthmakers [Heil]
     Full Idea: I do not understand how structures could serve as truthmakers for mathematical truths, ...Mathematical truths are not true in virtue of any way the universe is. ...Mathematical truths hold, whatever ways the universe is.
     From: John Heil (The Universe as We Find It [2012], 08.08)
     A reaction: I like the idea of enquiring about truthmakers for mathematical truths (and my view is more empirical than Heil's), but I think it may be a misunderstanding to think that structures are intended as truthmakers. Mathematics just IS structures?
7. Existence / C. Structure of Existence / 2. Reduction
Our categories lack the neat arrangement needed for reduction [Heil]
     Full Idea: Categories we use to describe and explain our universe do not line up in the neat way reductive schemes require.
     From: John Heil (The Universe as We Find It [2012], 13.2)
     A reaction: He takes reduction to be largely a relation between our categories, rather than between entities, so he is bound to get this result. He may be right.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / d. Commitment of theories
Fundamental ontology aims at the preconditions for any true theory [Heil]
     Full Idea: Fundamental ontology is in the business of telling us what the universe must be like if any theory is true.
     From: John Heil (The Universe as We Find It [2012], 01.1)
     A reaction: Heil is good at stating simple ideas simply. This seems to be a bold claim, but I think I agree with it.
7. Existence / D. Theories of Reality / 11. Ontological Commitment / e. Ontological commitment problems
Our quantifications only reveal the truths we accept; the ontology and truthmakers are another matter [Heil]
     Full Idea: Looking at what you quantify over reveals, at most, truths to which you are committed. What the ontology is, what the truthmakers are for these truths, is another matter, one tackled, if at all, only in the pursuit of fundamental physics.
     From: John Heil (The Universe as We Find It [2012], 08.08)
     A reaction: Exactly right. Nouns don't guarantee objects, verbs don't guarantee processes. If you want to know my ontological commitments, ask me about them! Don't infer them from the sentences I hold true, because they need interpreting.
7. Existence / E. Categories / 4. Category Realism
Ontology aims to give the fundamental categories of being [Heil]
     Full Idea: The task of ontology is to spell out the fundamental categories of being.
     From: John Heil (The Universe as We Find It [2012], 02.5)
     A reaction: This is the aspiration of 'pure' metaphysics, which I don't quite believe in. There is too much convention involved, on the one hand, and physics on the other.
8. Modes of Existence / A. Relations / 1. Nature of Relations
Most philosophers now (absurdly) believe that relations fully exist [Heil]
     Full Idea: It is a measure of how far we have fallen that so few philosophers nowadays see any difficulty at all in the idea that relations have full ontological standing.
     From: John Heil (The Universe as We Find It [2012], 01.4)
     A reaction: We have 'fallen' because medieval metaphysicians didn't believe it. Russell seems to have started, and the tendency to derive ontology from logic has secured the belief in relations. How else can you be allowed to write aRb? I agree with Heil.
8. Modes of Existence / A. Relations / 2. Internal Relations
If causal relations are power manifestations, that makes them internal relations [Heil]
     Full Idea: If causal relations are the manifesting of powers, then causal relations would appear to be a species of internal relation.
     From: John Heil (The Universe as We Find It [2012], 07.4)
     A reaction: The point being that any relations formed are entirely dependent on the internal powers of the relata. Sounds right. There are also non-causal relations, of course.
8. Modes of Existence / B. Properties / 2. Need for Properties
We need properties to explain how the world works [Heil]
     Full Idea: When a tomato depresses a scale, it does so in virtue of its mass - how it is masswise - and not in virtue of its colour or shape. Were we barred from saying such things, we would be unable to formulate truths about the fundamental things.
     From: John Heil (The Universe as We Find It [2012], 02.3)
     A reaction: It doesn't follow that we have an ontological commitment to properties, but we certainly need to point out the obvious fact that things being one way rather than another makes a difference to what happens.
8. Modes of Existence / B. Properties / 6. Categorical Properties
Categorical properties were introduced by philosophers as actual properties, not if-then properties [Heil]
     Full Idea: Categorical properties were introduced originally by philosophers bent on distinguishing properties possessed 'categorically', that is, actually, by objects from mere if-then, conditional properties, mere potentialities.
     From: John Heil (The Universe as We Find It [2012], 04.3)
     A reaction: He cites Ryle on dispositions in support. It is questionable whether it is a clear or useful distinction. Heil says the new distinction foreclosed the older more active view of properties.
Properties are respects in which particular objects may be alike or differ [Mellor/Oliver]
     Full Idea: Properties are respects in which particular objects may be alike or differ.
     From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §1)
     A reaction: Note that this definition does not mention a causal role for properties.
8. Modes of Existence / B. Properties / 7. Emergent Properties
Emergent properties will need emergent substances to bear them [Heil]
     Full Idea: If you are going to have emergent fundamental properties, you are going to need emergent fundamental substances as bearers of those properties.
     From: John Heil (The Universe as We Find It [2012], 02.6)
     A reaction: Presumably the theory of emergent properties (which I take to be nonsense, in its hardcore form) says that the substance is unchanged, but the property is new. Or else the bundle gives collective birth to a new member. Search me.
8. Modes of Existence / B. Properties / 10. Properties as Predicates
Predicates only match properties at the level of fundamentals [Heil]
     Full Idea: Only when you get to fundamental physics, do predicates begin to line up with properties.
     From: John Heil (The Universe as We Find It [2012], 13.2)
     A reaction: A nice thought. I assume the actual properties of daily reality only connect to our predicates in very sloppy ways. I suppose our fundamental predicates have to converge on the actual properties, because the fog clears. Sort of.
In Fa, F may not be a property of a, but a determinable, satisfied by some determinate [Heil]
     Full Idea: It may be that F applies truly to a because F is a determinable predicate satisfied by a's possession of a property answering to a determinate of that determinable predicate.
     From: John Heil (The Universe as We Find It [2012], 08.01)
     A reaction: Heil aims to break the commitment of predicates to the existence of properties. The point is that there is no property 'coloured' to correspond to 'a is coloured'. Red might be the determinate that does the job. Nice.
8. Modes of Existence / B. Properties / 11. Properties as Sets
Properties have causal roles which sets can't possibly have [Heil]
     Full Idea: Properties are central to the universe's causal order in a way that sets could not possibly be.
     From: John Heil (The Universe as We Find It [2012], 02.3)
     A reaction: The idea that properties actually are sets is just ridiculous. It may be that you can treat them as sets and get by quite well. The sets can be subsumed into descriptions of causal processes (or something).
8. Modes of Existence / B. Properties / 12. Denial of Properties
Nominalists ask why we should postulate properties at all [Mellor/Oliver]
     Full Idea: Nominalists ask why we should postulate properties at all.
     From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §3)
     A reaction: Objects might be grasped without language, but events cannot be understood, and explanations of events seem inconceivable without properties (implying that they are essentially causal).
8. Modes of Existence / C. Powers and Dispositions / 5. Powers and Properties
Are all properties powers, or are there also qualities, or do qualities have the powers? [Heil]
     Full Idea: Some philosophers who embrace properties as powers hold that every property is a power (Bird), or that some properties are qualities and some are powers (Ellis; Molnar). The latter include powers which are 'grounded in' qualities (Mumford).
     From: John Heil (The Universe as We Find It [2012], 04.4)
     A reaction: I don't like Heil's emphasis on 'qualities', which seems to imply their phenomenal rather than their real aspect. I'm inclined to favour the all-powers view, but can't answer the question 'but what HAS these powers?' Stuff is intrinsically powerful.
Properties are both qualitative and dispositional - they are powerful qualities [Heil]
     Full Idea: In my account of properties they are at once qualitative and dispositional: properties are powerful qualities.
     From: John Heil (The Universe as We Find It [2012], 05.1)
     A reaction: I have never managed to understand what Heil means by 'qualities'. Is he talking about the phenomenal aspects of powers? Does he mean categorical properties. I can't find an ontological space for his things to slot into.
9. Objects / A. Existence of Objects / 2. Abstract Objects / d. Problems with abstracta
Abstract objects wouldn't be very popular without the implicit idea of truthmakers [Heil]
     Full Idea: It would be difficult to understand the popularity of 'abstract entities' - numbers, sets, propositions - in the absence of an implicit acknowledgement of the importance of truthmakers.
     From: John Heil (The Universe as We Find It [2012], 08.07)
     A reaction: I love Idea 18496, because it leads us towards a better account of modality, but dislike this one because it reveals that the truthmaking idea has led us to a very poor theory. Truthmaking is a good question, but not much of an answer?
9. Objects / B. Unity of Objects / 2. Substance / a. Substance
Substances bear properties, so must be simple, and not consist of further substances [Heil]
     Full Idea: Substances, as property bearers, must be simple; substances of necessity lack constituents that are themselves substances.
     From: John Heil (The Universe as We Find It [2012], 01.3)
     A reaction: How can he think that this is a truth of pure metaphysics? A crowd has properties because we think of it as a simple substance, not because it actually is one. Can properties have properties? Are tree and leaf both substances?
9. Objects / C. Structure of Objects / 8. Parts of Objects / a. Parts of objects
Spatial parts are just regions, but objects depend on and are made up of substantial parts [Heil]
     Full Idea: An object is not made up of its spatial parts: spatial parts are regions of some object. ...Complex objects, wholes, are made up of, and so depend on, their substantial parts.
     From: John Heil (The Universe as We Find It [2012], 03.1)
     A reaction: Presumably objects also 'depend on' their spatial parts, so I am not convinced that we have a sharp distinction here.
A 'gunky' universe would literally have no parts at all [Heil]
     Full Idea: Blancmange 'gunky' universes are not just universes with an endless number of parts. Rather a blancmange universe is a universe with no simple parts, no parts themselves lacking parts.
     From: John Heil (The Universe as We Find It [2012], 03.3)
     A reaction: Hm. Lewis seemed to think it was parts all the way down. Is gunk homogeneous stuff, or what is endlessly subdividable, or an infinite shrinking of parts? We demand clarity.
9. Objects / C. Structure of Objects / 8. Parts of Objects / c. Wholes from parts
Many wholes can survive replacement of their parts [Heil]
     Full Idea: A whole - or some wholes - might be thought to survive gradual replacement of its parts, perhaps, but not their elimination.
     From: John Heil (The Universe as We Find It [2012], 03.1)
     A reaction: You can't casually replace the precious golden parts of a statue with cheap lead ones. It depends on whether the parts matter. Nevertheless this is a really important idea in metaphysics. It enables the s=Ship of Theseus to survive some change.
Dunes depend on sand grains, but line segments depend on the whole line [Heil]
     Full Idea: A sand dune depends on the individual grains of sand that make it up. In an important sense, however, a line's segments depend on the line rather than it on them.
     From: John Heil (The Universe as We Find It [2012], 03.4)
     A reaction: The illustrations are not clear cut. As you cut off segments of the line, you reduce its length. Heil is hoping for something neat here, but I don't think he has quite got. The difficulty of trying to do pure metaphysics!
10. Modality / C. Sources of Modality / 6. Necessity from Essence
If basic physics has natures, then why not reality itself? That would then found the deepest necessities [Heil]
     Full Idea: If electrons and gravitational fields have definite natures, why not reality itself? And if reality has a nature, if this makes sense, then reality grounds the deepest necessities of all.
     From: John Heil (The Universe as We Find It [2012], 08.09)
     A reaction: Nice speculation! Scientists and verificationists seem to cry 'foul!' when philosophers offer such wild speculations, but I say that's exactly what we pay them do. I'm not sure whether I understand reality having its own nature, though!
10. Modality / E. Possible worlds / 1. Possible Worlds / e. Against possible worlds
If possible worlds are just fictions, they can't be truthmakers for modal judgements [Heil]
     Full Idea: If the other possible worlds are merely useful fictions, we are left wondering what the truthmakers for all those modal judgements might be.
     From: John Heil (The Universe as We Find It [2012], 08.07)
     A reaction: I suddenly see that this is the train of thought that led me to believe in real powers and dispositions, and which retrospectively led me to love the truthmaker idea. Even real Lewisian worlds don't seem adequate as truthmakers here.
15. Nature of Minds / C. Capacities of Minds / 3. Abstraction by mind
Mental abstraction does not make what is abstracted mind-dependent [Heil]
     Full Idea: Talk of abstraction and 'partial consideration' (Locke) does not make what is abstracted mind-dependent. In abstracting, you attend to what is there to be considered.
     From: John Heil (The Universe as We Find It [2012], 05.7)
     A reaction: Quite so. The point is to focus on aspects of reality. Does anyone seriously doubt that reality has 'aspects'?
15. Nature of Minds / C. Capacities of Minds / 5. Generalisation by mind
Only particulars exist, and generality is our mode of presentation [Heil]
     Full Idea: Existing things are particular, and generality is a feature of our ways of representing the universe.
     From: John Heil (The Universe as We Find It [2012], 01.1)
     A reaction: This is right, and expressed with beautiful simplicity. How could anyone disagree with this? But they do!
16. Persons / F. Free Will / 5. Against Free Will
Saying we must will whatever we decide to will leads to an infinite regress [Leibniz]
     Full Idea: As for volition itself, to say that it is the object of free will is incorrect. We will to act, strictly speaking, and we do not will to will, else we should still say we will to have the will to will, and that would go on to infinity.
     From: Gottfried Leibniz (The Theodicy [1710], p.151), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 4.IV
     A reaction: This strikes me as an elementary difficulty which most fans of free will appear to evade. Thoughts just arise in us, and some of them are volitions. We can say there is then a 'gap' (Searle) where we choose, but what happens in the gap?
17. Mind and Body / A. Mind-Body Dualism / 5. Parallelism
Perfections of soul subordinate the body, but imperfections of soul submit to the body [Leibniz]
     Full Idea: Insofar as the soul has perfection ...God has accommodated the body to the soul, and has arranged beforehand that the body is impelled to execute its orders. Insofar as it is imperfect and confused, God accommodates soul to body, swayed by passions.
     From: Gottfried Leibniz (The Theodicy [1710], p.159), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 3.IV
     A reaction: Perkins says this is the nearest Leibniz gets to the idea of interaction between body and soul. Perfection and confusion are on a continuum for Leibniz. With such speculations I always wonder how these things can be known. How perfect is my mind?
18. Thought / A. Modes of Thought / 1. Thought
You can think of tomatoes without grasping what they are [Heil]
     Full Idea: You can entertain thoughts of things like tomatoes without a grasp of what they are.
     From: John Heil (The Universe as We Find It [2012], 08.10)
     A reaction: Lowe seemed to think that you had to grasp the generic essence of a tomato before you could think about it, but I agree entirely with Heil.
18. Thought / A. Modes of Thought / 8. Human Thought
Linguistic thought is just as imagistic as non-linguistic thought [Heil]
     Full Idea: Thinking - ordinary conscious thinking - is imagistic. This is so for 'linguistic' or 'sentential' thoughts as well as for patently non-linguistic thoughts.
     From: John Heil (The Universe as We Find It [2012], 12.10)
     A reaction: This claim (that linguistic thought is just as imagistic as non-linguistic thought) strikes me as an excellent insight.
Non-conscious thought may be unlike conscious thought [Heil]
     Full Idea: Non-conscious thought need not resemble conscious thought occurring out of sight.
     From: John Heil (The Universe as We Find It [2012], 12.10)
18. Thought / E. Abstraction / 5. Abstracta by Negation
Abstractions lack causes, effects and spatio-temporal locations [Mellor/Oliver]
     Full Idea: Abstract entities (such as sets) are usually understood as lacking causes, effects, and spatio-temporal location.
     From: DH Mellor / A Oliver (Introduction to 'Properties' [1997], §10)
     A reaction: This seems to beg some questions. Has the ideal of 'honour' never caused anything? Young men dream of pure velocity.
19. Language / C. Assigning Meanings / 3. Predicates
The subject-predicate form reflects reality [Heil]
     Full Idea: I like to think that the subject-predicate form reflects a fundamental division in reality.
     From: John Heil (The Universe as We Find It [2012], 10.1)
     A reaction: That is, he defends the idea that there are substances, and powerful qualities pertaining to those substances. I sympathise, but this slogan makes it too simple.
20. Action / B. Preliminaries of Action / 2. Willed Action / a. Will to Act
Will is an inclination to pursue something good [Leibniz]
     Full Idea: One may say that 'will' consists in the inclination to do something in proportion to the good it contains.
     From: Gottfried Leibniz (The Theodicy [1710], p.136), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.III
     A reaction: This emphasises that the will is faced with options, rather than generating the options. The context is a discussion of the nature of God's will. I think 'will' is a really useful concept, and dislike the Hobbesian rejection of will.
22. Metaethics / B. Value / 2. Values / a. Normativity
Many reject 'moral realism' because they can't see any truthmakers for normative judgements [Heil]
     Full Idea: It is the difficulty in imagining what truthmakers for normative judgements might be that leads many philosophers to find 'moral realism' unappealing.
     From: John Heil (The Universe as We Find It [2012], 08.07)
     A reaction: I like that a lot. My proposal for metaethics is that it should be built on the concept of a 'value-maker'
22. Metaethics / B. Value / 2. Values / e. Death
Most people facing death would happily re-live a similar life, with just a bit of variety [Leibniz]
     Full Idea: I believe there would be few persons who, being at the point of death, were not content to take up life again, on condition of passing through the same amount of good and evil, provided that it were not the same kind.
     From: Gottfried Leibniz (The Theodicy [1710], p.130), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
     A reaction: Nice challenge. People who refuse the offer are not necessarily suicidal. He's probably right, but Leibniz doesn't recognise the factor of boredom. Look up the suicide note of the actor George Sanders! One life may be enough.
22. Metaethics / B. Value / 2. Values / j. Evil
Metaphysical evil is imperfection; physical evil is suffering; moral evil is sin [Leibniz]
     Full Idea: Evil may be taken metaphysically, physically, and morally. Metaphysical evil consists in mere imperfection, physical evil is suffering, and moral evil is sin.
     From: Gottfried Leibniz (The Theodicy [1710], p.136), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
     A reaction: There seem to be plenty of imperfections in the world which don't look like evil. Or do you only declare it to be an imperfection because it seems to be evil (by some other standard)? Human evil comes from ignorance, so metaphysical explains moral.
22. Metaethics / C. The Good / 1. Goodness / g. Consequentialism
You can't assess moral actions without referring to the qualities of character that produce them [Leibniz]
     Full Idea: One is more worthy of praise when one owes the action to one's good qualities, and more culpable in proportion as one has been impelled by one's evil qualities; assessing actions without weighing the qualities whence they spring is to talk at random.
     From: Gottfried Leibniz (The Theodicy [1710], p.426), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 4.IV
     A reaction: Mill tries to separate judgement of the agent from judgement of the consequences of the action, but I think Leibniz has spotted that just judging outcomes ceases to be a 'moral' judgement.
26. Natural Theory / A. Speculations on Nature / 5. Infinite in Nature
If there were infinite electrons, they could vanish without affecting total mass-energy [Heil]
     Full Idea: In a universe containing an infinite number of electrons would mass-energy be conserved? ...Electrons could come and go without affecting the total mass-energy.
     From: John Heil (The Universe as We Find It [2012], 03.6)
     A reaction: This seems to be a very persuasive reason for doubting that the universe contains an infinite number of electrons. In fact I suspect that infinite numbers have no bearing on nature at all. (Actually, I suspect them of being fictions).
26. Natural Theory / C. Causation / 8. Particular Causation / a. Observation of causation
We should focus on actual causings, rather than on laws and causal sequences [Heil]
     Full Idea: I believe our understanding of causation would benefit from a shift of attention from causal sequences and laws, to instances of causation: 'causings'.
     From: John Heil (The Universe as We Find It [2012], 06.1)
     A reaction: His aim is to get away from generalities, and focus on the actual operation of powers which is involved. He likes the case of two playing cards propped against one another. I'm on his side. Laws come last in the story, and should not come first.
26. Natural Theory / C. Causation / 8. Particular Causation / e. Probabilistic causation
Probabilistic causation is not a weak type of cause; it is just a probability of there being a cause [Heil]
     Full Idea: The label 'probabilistic causation' is misleading. What you have is not a weakened or tentative kind of causing, but a probability of there being a cause.
     From: John Heil (The Universe as We Find It [2012], 06.5)
     A reaction: The idea of 'probabilistic causation' strikes me as an empty philosophers' concoction, so I agree with Heil.
27. Natural Reality / B. Modern Physics / 2. Electrodynamics / c. Electrons
Electrons are treated as particles, but they lose their individuality in relations [Heil]
     Full Idea: Although it is convenient to speak of electrons as particles or elementary substances, when they enter into relations they can 'lose their individuality. Then an electron becomes a kind of 'abstract particular', a way a given system is, a mode.
     From: John Heil (The Universe as We Find It [2012], 03.7)
     A reaction: Heil rightly warns us against basing our metaphysics on disputed theories of quantum mechanics.
27. Natural Reality / E. Cosmology / 9. Fine-Tuned Universe
Maybe the universe is fine-tuned because it had to be, despite plans by God or Nature? [Heil]
     Full Idea: Maybe the universe is fine-tuned as it is, not because things happened to fall out as they did during and immediately after the Big Bang, or because God so ordained it, but because God or the Big Bang had no choice.
     From: John Heil (The Universe as We Find It [2012], 08.09)
     A reaction: You'd be hard put to so why it had to be fine-tuned, so this seems to be a nice speculation. Unverifiable but wholly meaningful. Maybe the stuff fine-tunes itself, by mutual interaction. Or it is the result of natural selection (Lee Smolin).
28. God / A. Divine Nature / 2. Divine Nature
God must be intelligible, to select the actual world from the possibilities [Leibniz]
     Full Idea: The cause of the world must be intelligent: for this existing world being contingent and an infinity of worlds being equally possible, with equal claim to existence, the cause of the world must have regarded all of these worlds to fix on one of them.
     From: Gottfried Leibniz (The Theodicy [1710], p.127), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
     A reaction: A wonderfully Leibnizian way of putting what looks like the design argument.
28. God / A. Divine Nature / 3. Divine Perfections
The intelligent cause must be unique and all-perfect, to handle all the interconnected possibilities [Leibniz]
     Full Idea: The intelligent cause ought to be infinite in all ways, and absolutely perfect in power, in wisdom, and in goodness, since it relates to all that which is possible. Also, since all is connected together, there is no ground for admitting more than one.
     From: Gottfried Leibniz (The Theodicy [1710], p.128), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
     A reaction: Notice that Leibniz's possible worlds seem to be all connected together, unlike David Lewis's worlds, which are discrete. Personally I suspect that all perfections will lead to contradiction, though Leibniz strongly argues against it.
28. God / A. Divine Nature / 6. Divine Morality / a. Divine morality
God prefers men to lions, but might not exterminate lions to save one man [Leibniz]
     Full Idea: It is certain that God sets greater store by a man than a lion; nevertheless it can hardly be said with certainty that God prefers a single man in all respects to the whole of lion-kind.
     From: Gottfried Leibniz (The Theodicy [1710], p.189), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
     A reaction: Lovely problems arise when you guess at God's values! We have the same problem. Would you kill a poacher who was wiping out the last remaining lions? How many lions would you kill to save a human?
28. God / A. Divine Nature / 6. Divine Morality / b. Euthyphro question
If justice is arbitrary, or fixed but not observed, or not human justice, this undermines God [Leibniz]
     Full Idea: The three dogmas (1) that the nature of justice is arbitrary, (2) it is fixed, but not certain God will observe it, or (3) the justice we know is not that which God observes, destroy our confidence in the love of God.
     From: Gottfried Leibniz (The Theodicy [1710], p.237), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.III
     A reaction: Leibniz proceeds to carefully refute these three responses to the dilemma about how justice relates to God.
28. God / B. Proving God / 2. Proofs of Reason / a. Ontological Proof
God is the first reason of things; our experiences are contingent, and contain no necessity [Leibniz]
     Full Idea: God is the first reason of things: all that we see and experience is contingent and nothing in them renders their existence necessary.
     From: Gottfried Leibniz (The Theodicy [1710], p.127), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
     A reaction: Perkins presents this as the first step in one of Leibniz's arguments for God. They all seem to be variants of the ontological argument. [His 'Theodicy' is the Huggard translation, 1985] This resembles Aquinas's Third Way.
28. God / B. Proving God / 3. Proofs of Evidence / b. Teleological Proof
The laws of physics are wonderful evidence of an intelligent and free being [Leibniz]
     Full Idea: These admirable laws [of physics] are wonderful evidence of an intelligent and free being, as opposed to the system of absolute and brute necessity, advocated by Strato and Spinoza.
     From: Gottfried Leibniz (The Theodicy [1710], p.332), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.II
     A reaction: Note the swipe at Spinoza. Leibniz defends the absolute necessities residing in God, but is too polite to call those 'brute', though personally I can't see the difference. But he says the laws arise from 'perfection and order', not from God's necessity.
29. Religion / D. Religious Issues / 1. Religious Commitment / a. Religious Belief
Prayers are useful, because God foresaw them in his great plan [Leibniz]
     Full Idea: Not only cares and labours but also prayers are useful; God having had these prayers in view before he regulated things.
     From: Gottfried Leibniz (The Theodicy [1710], Abridge III)
     A reaction: Hm. I'm struggling with this one. So I can't skip prayers today, because God has foreseen them and included them in his great plan? Hard to motivate yourself, like starting a game of chess after you've already been declared the winner.
29. Religion / D. Religious Issues / 3. Problem of Evil / a. Problem of Evil
How can an all-good, wise and powerful being allow evil, sin and apparent injustice? [Leibniz]
     Full Idea: There is this question of natural theology, how a sole Principle, all-good, all-wise and all-powerful, has been able to admit evil, and especially to permit sin, and how it could resolve to make the wicked often happy and the good unhappy?
     From: Gottfried Leibniz (The Theodicy [1710], p.098), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
     A reaction: His answer is, roughly, that there is an unavoidable trade-off, which humans cannot fully understand. Personally I would say that if there is a God, the evidence for his benevolence towards humanity is not encouraging.
Being confident of God's goodness, we disregard the apparent local evils in the visible world [Leibniz]
     Full Idea: Being made confident by demonstrations of the goodness and the justice of God, we disregard the appearances of harshness and justice which we see in this small portion of his Kingdom that is exposed to our gaze.
     From: Gottfried Leibniz (The Theodicy [1710], p.120), quoted by Franklin Perkins - Leibniz: Guide for the Perplexed 2.IV
     A reaction: Hm. If this locality is full of evils, and the rest of it is much better, how come we are stuck in this miserable corner of things? God is obliged to compromise, but did he select us to get the worst of it?
