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.
1. Philosophy / E. Nature of Metaphysics / 6. Metaphysics as Conceptual
Many philosophers aim to understand metaphysics by studying ourselves [Chisholm]
     Full Idea: Leibniz, Reid, Brentano and others have held that, by considering certain obvious facts about ourselves, we can arrive at an understanding of the general principles of metaphysics. The present book is intended to confirm that view.
     From: Roderick Chisholm (Person and Object [1976], Intro 1)
     A reaction: I sympathise, but don't really agree. I see metaphysics as a process of filtering ourselves out of the picture, leaving an account of how things actually are.
1. Philosophy / F. Analytic Philosophy / 6. Logical Analysis
I use variables to show that each item remains the same entity throughout [Chisholm]
     Full Idea: My use of variables is not merely pedantic; it indicates that the various items on our list pertain to one and the same entity throughout.
     From: Roderick Chisholm (Person and Object [1976], Intro 2)
     A reaction: I am one of those poor souls who finds modern analytic philosophy challenging simply because I think in terms of old fashioned words, instead of thinking like mathematicians and logicians. This is a nice defence of their approach.
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 / B. Change in Existence / 4. Events / a. Nature of events
Events are states of affairs that occur at certain places and times [Chisholm]
     Full Idea: We will restrict events to those states of affairs which occur at certain places and times.
     From: Roderick Chisholm (Person and Object [1976], 4.6)
     A reaction: If I say 'the bomb may explode sometime', that doesn't seem to refer to an event. Philosophers like Chisholm bowl along, defining left, right and centre, and never seem to step back from their system and ask obvious critical questions.
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 / 9. States of Affairs
The mark of a state of affairs is that it is capable of being accepted [Chisholm]
     Full Idea: We will say that the mark of a state of affairs is the fact that it is capable of being accepted.
     From: Roderick Chisholm (Person and Object [1976], 4.2)
     A reaction: I find this a quite bewildering proposal. It means that it is impossible for there to be a state of affairs which is beyond human conception, but why commit to that?
A state of affairs pertains to a thing if it implies that it has some property [Chisholm]
     Full Idea: A state of affairs pertains to a thing if it implies the thing to have a certain property.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: For this to work, we must include extrinsic and relational properties, and properties which are derived from mere predication. I think this is bad metaphysics, and leads to endless confusions.
I propose that events and propositions are two types of states of affairs [Chisholm]
     Full Idea: I will propose that events are said to constitute one type of states of affairs, and propositions another
     From: Roderick Chisholm (Person and Object [1976], 4.1)
     A reaction: I would much prefer to distinguish between the static and the dynamic, so we have a static or timeless state of affairs, and a dynamic event or process. Propositions I take to be neither. He really means 'facts', which subsume the whole lot.
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 / 1. Nature of Properties
Some properties can never be had, like being a round square [Chisholm]
     Full Idea: There are properties which nothing can possibly have; an example is the property of being both round and square.
     From: Roderick Chisholm (Person and Object [1976], 4.2)
     A reaction: This is a rather bizarre Meinongian claim. For a start it sounds like two properties not one. Is there a property of being both 'over here' and 'over there'? We might say the round-square property must exist, for God to fail to implement it (?)
Some properties, such as 'being a widow', can be seen as 'rooted outside the time they are had' [Chisholm]
     Full Idea: Some properties may be said to be 'rooted outside the times at which they are had'. Examples are the property of being a widow and the property of being a future President.
     From: Roderick Chisholm (Person and Object [1976], 3.4)
     A reaction: This is the sort of mess you when you treat the category in which an object belongs as if it was one of its properties. We categorise because of properties.
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.
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
If some dogs are brown, that entails the properties of 'being brown' and 'being canine' [Chisholm]
     Full Idea: The state of affairs which is some dogs being brown may be said to entail (make it necessarily so) the property of 'being brown', as well as the properties of 'being canine' and 'being both brown and canine'.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: And the property of 'being such that it is both brown and canine and brown or canine'. Etc. This is dangerous nonsense. Making all truths entail the existence of some property means we can no longer get to grips with real properties.
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 / 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 / A. Existence of Objects / 5. Individuation / a. Individuation
Maybe we can only individuate things by relating them to ourselves [Chisholm]
     Full Idea: It may well be that the only way we have, ultimately, of individuating anything is to relate it uniquely to ourselves.
     From: Roderick Chisholm (Person and Object [1976], 1.5)
     A reaction: I'm guessing that Chisholm is thinking of 'ourselves' as meaning just himself, but I'm thinking this is plausible if he means the human community. I doubt whether there is much a philosopher can say on individuation that is revealing or precise.
9. Objects / A. Existence of Objects / 5. Individuation / d. Individuation by haecceity
Being the tallest man is an 'individual concept', but not a haecceity [Chisholm]
     Full Idea: Being the tallest man and being President of the United States are 'individual concepts', but not haecceities.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: Chisholm introduces this term, to help him explain his haecceity more clearly. (His proposal on that adds a lot of fog to this area of metaphysics).
A haecceity is a property had necessarily, and strictly confined to one entity [Chisholm]
     Full Idea: An individual essence or haecceity is a narrower type of individual concept. This is a property which is had necessarily, and which it is impossible for any other thing to have.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: [Apologies to Chisholm for leaving out the variables from his definition of haecceity. See Idea 15802] See also Idea 15805. The tallest man is unique, but someone else could become the tallest man. No one else could acquire 'being Socrates'.
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 / 7. Substratum
A peach is sweet and fuzzy, but it doesn't 'have' those qualities [Chisholm]
     Full Idea: Our idea of a peach is not an idea of something that 'has' those particular qualities, but the concrete thing that 'is' sweet and round and fuzzy.
     From: Roderick Chisholm (Person and Object [1976], 1.6)
     A reaction: This is the beginnings of his 'adverbial' account of properties, with which you have to sympathise. It tries to eliminate the possibility of some propertyless thing, to which properties can then be added, like sprinkling sugar on it.
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 / b. Sums of parts
If x is ever part of y, then y is necessarily such that x is part of y at any time that y exists [Chisholm, by Simons]
     Full Idea: Chisholm has an axiom: if x is a proper part of y, then necessarily if y exists then x is part of it. If x is ever part of y, they y is necessarily such that x is part of y at any time that y exists.
     From: report of Roderick Chisholm (Person and Object [1976], p.149) by Peter Simons - Parts 5.3
     A reaction: This is Chisholm's notorious mereological essentialism, that all parts are necessary, and change of part means change of thing. However, it looks to me more like a proposal about what properties are necessary, not what are essential.
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!
9. Objects / D. Essence of Objects / 3. Individual Essences
A traditional individual essence includes all of a thing's necessary characteristics [Chisholm]
     Full Idea: According to the traditional account of individual essence, each thing has only one individual essence and it includes all the characteristics that the thing has necessarily.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: Chisholm is steeped in medieval theology, but I don't think this is quite what Aristotle meant. Everyone nowadays has to exclude the 'trivial' necessary properties, for a start. But why? I'm contemplating things which survive the loss of their essence.
9. Objects / E. Objects over Time / 7. Intermittent Objects
Intermittence is seen in a toy fort, which is dismantled then rebuilt with the same bricks [Chisholm, by Simons]
     Full Idea: Chisholm poses the problem of intermittence with the case of a toy fort which is built from toy bricks, taken apart, and then reassembled with the same bricks in the same position.
     From: report of Roderick Chisholm (Person and Object [1976], p.90) by Peter Simons - Parts 5.3
     A reaction: You could strengthen the case, or the problem, by using those very bricks to build a ship during the interval. Or building a fort with a different design. Most people would be happy to say that same object (token) has been rebuilt.
9. Objects / F. Identity among Objects / 5. Self-Identity
The property of being identical with me is an individual concept [Chisholm]
     Full Idea: I wish to urge that the property of being identical with me is an individual concept.
     From: Roderick Chisholm (Person and Object [1976], 1.4)
     A reaction: I can just about live with the claim (for formal purposes) that I am identical with myself, but I strongly resist my then having a 'property' consisting of 'being identical with myself' (or 'not being identical with somone else' etc.).
9. Objects / F. Identity among Objects / 9. Sameness
There is 'loose' identity between things if their properties, or truths about them, might differ [Chisholm]
     Full Idea: I suggest that there is a 'loose' sense of identity that is consistent with saying 'A has a property that B does not have', or 'some things are true of A but not of B'.
     From: Roderick Chisholm (Person and Object [1976], 3.2)
     A reaction: He is trying to explicate Bishop Butler's famous distinction between 'strict and philosophical' and 'loose and popular' senses. We might want to claim that the genuine identity relation is the 'loose' one (pace the logicians and mathematicians).
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.
12. Knowledge Sources / B. Perception / 4. Sense Data / d. Sense-data problems
Do sense-data have structure, location, weight, and constituting matter? [Chisholm]
     Full Idea: Does a red sense-datum or appearance have a back side as well as a front? Where is it located? Does it have any weight? What is it made of?
     From: Roderick Chisholm (Person and Object [1976], 1.8)
     A reaction: A reductive physicalist like myself is not so troubled by questions like this, which smack of Descartes's non-spatial argument for dualism.
12. Knowledge Sources / B. Perception / 8. Adverbial Theory
'I feel depressed' is more like 'he runs slowly' than like 'he has a red book' [Chisholm]
     Full Idea: The sentences 'I feel depressed' and 'I feel exuberant' are related in the way in which 'He runs slowly' and 'He runs swiftly' are related, and not in the way in which 'He has a red book' and 'He has a brown book' are related.
     From: Roderick Chisholm (Person and Object [1976], 1.8)
     A reaction: Ducasse 1942 and Chisholm 1957 seem to be the sources of the adverbial theory. I gather Chisholm gave it up late in his career. The adverbial theory seems sort of right, but it doesn't illuminate what is happening.
If we can say a man senses 'redly', why not also 'rectangularly'? [Chisholm]
     Full Idea: If we say a man 'senses redly', may we also say that he 'senses rhomboidally' or 'senses rectangularly'? There is no reason why not.
     From: Roderick Chisholm (Person and Object [1976], 1.8)
     A reaction: This is Chisholm replying to one of the best known objections to the adverbial theory. Can we sense 'wobblyrhomboidallywithpinkdots-ly'? Can we perceive 'landscapely'? The problem is bigger than he thinks.
So called 'sense-data' are best seen as 'modifications' of the person experiencing them [Chisholm]
     Full Idea: We may summarise my way of looking at appearing by saying that so-called appearances or sense-data are 'affections' or 'modifications' of the person who is said to experience them.
     From: Roderick Chisholm (Person and Object [1976], 1.8)
     A reaction: Hm. That seems to transfer the ontological problem of the redness of the tomato from the tomato to the perceiver, but leave the basic difficulty untouched. I think we need to pull apart the intrinsic and subjective ingredients here.
14. Science / D. Explanation / 1. Explanation / a. Explanation
Explanations have states of affairs as their objects [Chisholm]
     Full Idea: I suggest that states of affairs constitute the objects of the theory of explanation.
     From: Roderick Chisholm (Person and Object [1976], 4.4)
     A reaction: It is good to ask what the constituents of a theory of explanation might be. He has an all-embracing notion of state of affairs, whereas I would say that events and processes are separate. See Idea 15828.
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 / B. Nature of the Self / 3. Self as Non-physical
I am picked out uniquely by my individual essence, which is 'being identical with myself' [Chisholm]
     Full Idea: What picks me out uniquely, without relating me to some other being? It can only be the property of 'being me' or 'being identical with myself', which can only be an individual essence or haecceity, a property I cannot fail to have.
     From: Roderick Chisholm (Person and Object [1976], 1.5)
     A reaction: Only a philosopher (and a modern analytic one at that) would imagine that this was some crucial insight into how we know our own identities.
16. Persons / C. Self-Awareness / 3. Limits of Introspection
Sartre says the ego is 'opaque'; I prefer to say that it is 'transparent' [Chisholm]
     Full Idea: Sartre says the ego is 'opaque'; I would think it better to say that the ego is 'transparent'.
     From: Roderick Chisholm (Person and Object [1976], 1.8)
     A reaction: Insofar as we evidently have a self, I would say it is neither. It is directly experienced, through willing, motivation, and mental focus.
16. Persons / D. Continuity of the Self / 3. Reference of 'I'
People use 'I' to refer to themselves, with the meaning of their own individual essence [Chisholm]
     Full Idea: Each person uses the first person pronoun to refer to himself, and in such a way that its reference (Bedeutung) is to himself and its intention (Sinn) is his own individual essence.
     From: Roderick Chisholm (Person and Object [1976], 1.5)
     A reaction: I think this is exactly right, and may be the basis of the way we essentialise in our understanding of the rest of reality. I have a strong notion of what is essential in me and what is not.
16. Persons / E. Rejecting the Self / 1. Self as Indeterminate
Bad theories of the self see it as abstract, or as a bundle, or as a process [Chisholm]
     Full Idea: Some very strange theories of the self suggest it is an abstract object, such as a class, or a property, or a function. Some theories imply that I am a collection, or a bundle, or a structure, or an event, or a process (or even a verb!).
     From: Roderick Chisholm (Person and Object [1976], Intro 4)
     A reaction: I certainly reject the abstract lot, but the second lot doesn't sound so silly to me, especially 'structure' and 'process'. I don't buy the idea that the Self is an indivisible monad. It is a central aspect of brain process - the prioritiser of thought.
16. Persons / F. Free Will / 5. Against Free Will
Determinism claims that every event has a sufficient causal pre-condition [Chisholm]
     Full Idea: Determinism is the proposition that, for every event that occurs, there occurs a sufficient causal condition of that event.
     From: Roderick Chisholm (Person and Object [1976], 2.2)
     A reaction: You need an ontology of events to put it precisely this way. Doesn't it also work the other way: that there is an event for every sufficient causal condition? The beginning and the end of reality pose problems.
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
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)
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.
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 / C. Motives for Action / 5. Action Dilemmas / c. Omissions
There are mere omissions (through ignorance, perhaps), and people can 'commit an omission' [Chisholm]
     Full Idea: If a man does not respond to a greeting, if he was unaware that he was addressed then his failure to respond may be a mere omission. But if he intended to snub the man, then he could be said to have 'committed the omission'.
     From: Roderick Chisholm (Person and Object [1976], 2.6)
     A reaction: Chisholm has an extensive knowledge of Catholic theology. These neat divisions are subject to vagueness and a continuum of cases in real life.
21. Aesthetics / C. Artistic Issues / 7. Art and Morality
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?
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'
26. Natural Theory / A. Speculations on Nature / 1. Nature
The concept of physical necessity is basic to both causation, and to the concept of nature [Chisholm]
     Full Idea: It is generally agreed, I think, that the concept of physical necessity, or a law of nature, is fundamental to the theory of causation and, more generally, to the concept of nature.
     From: Roderick Chisholm (Person and Object [1976], 2.3)
     A reaction: This seems intuitively right, but we might be able to formulate a concept of nature that had a bit less necessity in it, especially if we read a few books on quantum theory first.
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 / 2. Types of cause
Some propose a distinct 'agent causation', as well as 'event causation' [Chisholm]
     Full Idea: Sometimes a distinction is made between 'event causation' and 'agent causation' and it has been suggested that there is an unbridgeable gap between the two.
     From: Roderick Chisholm (Person and Object [1976], 2.5)
     A reaction: Nope, don't buy that. I connect it with Davidson's 'anomalous monism', that tries to combine one substance with separate laws of action. The metaphysical price for such a theory is too high to pay.
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.
26. Natural Theory / D. Laws of Nature / 7. Strictness of Laws
A 'law of nature' is just something which is physically necessary [Chisholm]
     Full Idea: When we say something is 'physically necessary' we can replace it with 'law of nature'.
     From: Roderick Chisholm (Person and Object [1976], 2.2)
     A reaction: [plucked out of context even more than usual!] This is illuminating about what contemporary philosophers (such as Armstrong) seem to mean by a law of nature. It is not some grand equation, but a small local necessary connection.
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).
