22611 | Metaphysics can criticise interpretations of science theories, and give good feedback [Ingthorsson] |
Full Idea: Metaphysics is capable of critical scrutiny of the way the empirical sciences make sense of their own theories, and can provide them with very useful feedback. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.9) | |
A reaction: I agree with this, but I don't think it is the main job of metaphysics, which has its own agenda, using science as some of its raw material. |
224 | When questions are doubtful we should concentrate not on objects but on ideas of the intellect [Plato] |
Full Idea: Doubtful questions should not be discussed in terms of visible objects or in relation to them, but only with reference to ideas conceived by the intellect. | |
From: Plato (Parmenides [c.364 BCE], 135e) |
232 | Opposites are as unlike as possible [Plato] |
Full Idea: Opposites are as unlike as possible. | |
From: Plato (Parmenides [c.364 BCE], 159a) |
8937 | Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic [Hegel on Plato] |
Full Idea: Plato's 'Parmenides' is the greatest artistic achievement of the ancient dialectic. | |
From: comment on Plato (Parmenides [c.364 BCE]) by Georg W.F.Hegel - Phenomenology of Spirit Pref 71 | |
A reaction: It is a long way from the analytic tradition of philosophy to be singling out a classic text for its 'artistic' achievement. Eventually we may even look back on, say, Kripke's 'Naming and Necessity' and see it in that light. |
22609 | Philosophers accepted first-order logic, because they took science to be descriptive, not explanatory [Ingthorsson] |
Full Idea: First-order predicate logic was accepted so easily by the philosophical community …because philosophy was already geared toward a neo-Humean view of both science and philosophy as primarily descriptive rather than explanatory. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.8) | |
A reaction: The point, I think, is that explanatory thinking needs second-order logic, where the properties (or powers) are players in the game, and not just adjuncts of the catalogue of objects. I find this idea mind-expanding. (That's a good thing). |
13986 | Plato found antinomies in ideas, Kant in space and time, and Bradley in relations [Plato, by Ryle] |
Full Idea: Plato (in 'Parmenides') shows that the theory that 'Eide' are substances, and Kant that space and time are substances, and Bradley that relations are substances, all lead to aninomies. | |
From: report of Plato (Parmenides [c.364 BCE]) by Gilbert Ryle - Are there propositions? 'Objections' |
14150 | Plato's 'Parmenides' is perhaps the best collection of antinomies ever made [Russell on Plato] |
Full Idea: Plato's 'Parmenides' is perhaps the best collection of antinomies ever made. | |
From: comment on Plato (Parmenides [c.364 BCE]) by Bertrand Russell - The Principles of Mathematics §337 |
16150 | One is, so numbers exist, so endless numbers exist, and each one must partake of being [Plato] |
Full Idea: If one is, there must also necessarily be number - Necessarily - But if there is number, there would be many, and an unlimited multitude of beings. ..So if all partakes of being, each part of number would also partake of it. | |
From: Plato (Parmenides [c.364 BCE], 144a) | |
A reaction: This seems to commit to numbers having being, then to too many numbers, and hence to too much being - but without backing down and wondering whether numbers had being after all. Aristotle disagreed. |
229 | The one was and is and will be and was becoming and is becoming and will become [Plato] |
Full Idea: The one was and is and will be and was becoming and is becoming and will become. | |
From: Plato (Parmenides [c.364 BCE], 155d) |
21821 | Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus] |
Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many. | |
From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08 | |
A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God. |
22629 | Basic processes are said to be either physical, or organic, or psychological [Ingthorsson] |
Full Idea: Process philosophy is considered to include ideas of process as basically physical (Whitehead 1929), as basically organic (Bergson 1910), and as basically psychological (James 1890). | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7.4) | |
A reaction: I take Whitehead to be the only serious contender here. |
22633 | Indirect realists are cautious about the manifest image, and prefer the scientific image [Ingthorsson] |
Full Idea: The indirect realist regards the manifest image with scepticism and contrasts it to the scientific image. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8.13) | |
A reaction: This is why indirect realism is the best view for a realist who largely accepts the authority of science, Philosophers can wallow in the manifest image all they like (and most of them seem to love it), but truth is in the scientific image. |
221 | Absolute ideas, such as the Good and the Beautiful, cannot be known by us [Plato] |
Full Idea: The absolute good and the beautiful and all which we conceive to be absolute ideas are unknown to us. | |
From: Plato (Parmenides [c.364 BCE], 134c) |
22606 | Neo-Humeans say there are no substantial connections between anything [Ingthorsson] |
Full Idea: Neo-Humean metaphysics holds the view that there are no substantial connections between anything in this world. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1) | |
A reaction: A very illuminating comment. This exactly fits Lewis's great 'mosaic' of facts. The challenge is to say what 'substantial' relations there might be, but I'm quite happy to have a go at that. |
22631 | Properties are said to be categorical qualities or non-qualitative dispositions [Ingthorsson] |
Full Idea: It is said that that properties divide into two mutually exclusive types—non-dispositional qualities (sometimes called 'categorical properties’) vs. non-qualitative dispositions—of which the qualities are more fundamental than dispositions. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8) | |
A reaction: It is standardly understood that the qualitative categorical properties are more fundamental. Fans of powers (such as Ingthorsson and myself) either favour the dispositional properties, or reject the distinction. |
22632 | Physics understands the charge of an electron as a power, not as a quality [Ingthorsson] |
Full Idea: Is the negative charge of an electron a quality or power? It is clear that physics describes the nature of charge only in terms of what its bearer can do. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 8.06) | |
A reaction: The point is that an electron has properties, even though it has no observable qualities. Ingthorsson says the scientific concept of qualities is entirely about what something can do, and ot how it is perceived. |
223 | If you deny that each thing always stays the same, you destroy the possibility of discussion [Plato] |
Full Idea: If a person denies that the idea of each thing is always the same, he will utterly destroy the power of carrying on discussion. | |
From: Plato (Parmenides [c.364 BCE], 135c) |
227 | You must always mean the same thing when you utter the same name [Plato] |
Full Idea: You must always mean the same thing when you utter the same name. | |
From: Plato (Parmenides [c.364 BCE], 147d) |
211 | If admirable things have Forms, maybe everything else does as well [Plato] |
Full Idea: It is troubling that if admirable things have abstract ideas, then perhaps everything else must have ideas as well. | |
From: Plato (Parmenides [c.364 BCE], 130d) |
228 | Greatness and smallness must exist, to be opposed to one another, and come into being in things [Plato] |
Full Idea: These two ideas, greatness and smallness, exist, do they not? For if they did not exist, they could not be opposites of one another, and could not come into being in things. | |
From: Plato (Parmenides [c.364 BCE], 149e) |
210 | It would be absurd to think there were abstract Forms for vile things like hair, mud and dirt [Plato] |
Full Idea: Are there abstract ideas for such things as hair, mud and dirt, which are particularly vile and worthless? That would be quite absurd. | |
From: Plato (Parmenides [c.364 BCE], 130d) |
16151 | Plato moves from Forms to a theory of genera and principles in his later work [Plato, by Frede,M] |
Full Idea: It seems to me that Plato in the later dialogues, beginning with the second half of 'Parmenides', wants to substitute a theory of genera and theory of principles that constitute these genera for the earlier theory of forms. | |
From: report of Plato (Parmenides [c.364 BCE]) by Michael Frede - Title, Unity, Authenticity of the 'Categories' V | |
A reaction: My theory is that the later Plato came under the influence of the brilliant young Aristotle, and this idea is a symptom of it. The theory of 'principles' sounds like hylomorphism to me. |
219 | If absolute ideas existed in us, they would cease to be absolute [Plato] |
Full Idea: None of the absolute ideas exists in us, because then it would no longer be absolute. | |
From: Plato (Parmenides [c.364 BCE], 133c) |
220 | The concept of a master includes the concept of a slave [Plato] |
Full Idea: Mastership in the abstract is mastership of slavery in the abstract. | |
From: Plato (Parmenides [c.364 BCE], 133e) |
218 | Participation is not by means of similarity, so we are looking for some other method of participation [Plato] |
Full Idea: Participation is not by means of likeness, so we must seek some other method of participation. | |
From: Plato (Parmenides [c.364 BCE], 133a) |
212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it. | |
From: Plato (Parmenides [c.364 BCE], 131a) |
215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think? | |
From: Plato (Parmenides [c.364 BCE], 132c) |
213 | Each idea is in all its participants at once, just as daytime is a unity but in many separate places at once [Plato] |
Full Idea: Just as day is in many places at once, but not separated from itself, so each idea might be in all its participants at once. | |
From: Plato (Parmenides [c.364 BCE], 131b) |
216 | If things are made alike by participating in something, that thing will be the absolute idea [Plato] |
Full Idea: That by participation in which like things are made like, will be the absolute idea, will it not? | |
From: Plato (Parmenides [c.364 BCE], 132e) |
214 | If absolute greatness and great things are seen as the same, another thing appears which makes them seem great [Plato] |
Full Idea: If you regard the absolute great and the many great things in the same way, will not another appear beyond, by which all these must appear to be great? | |
From: Plato (Parmenides [c.364 BCE], 132a) |
217 | Nothing can be like an absolute idea, because a third idea intervenes to make them alike (leading to a regress) [Plato] |
Full Idea: It is impossible for anything to be like an absolute idea, because a third idea will appear to make them alike, and if that is like anything, it will lead to another idea, and so on. | |
From: Plato (Parmenides [c.364 BCE], 133a) |
22627 | Compound objects are processes, insofar as change is essential to them [Ingthorsson] |
Full Idea: Compound objects are to be considered processes, if by ‘process’ we mean any entity for which change is essential for its continued existence. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7) | |
A reaction: This doesn't seem to matter much, except to challenge those who say that reality consists of processes, and therefore not of substances. |
22613 | Most materialist views postulate smallest indivisible components which are permanent [Ingthorsson] |
Full Idea: Most materialist ontologies of the past postulate that the world ultimately consists of smallest indivisible component parts that persist because they must; they are permanent. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
A reaction: Van Inwagen is notable for this view. Ingthorsson says the theory is to explain medium-sized change, while denying that anything comes to be out of nothing. Theology may lurk in the background. Simple persistance won't explain compound persistance. |
15851 | Parts must belong to a created thing with a distinct form [Plato] |
Full Idea: The part would not be the part of many things or all, but of some one character ['ideas'] and of some one thing, which we call a 'whole', since it has come to be one complete [perfected] thing composed [created] of all. | |
From: Plato (Parmenides [c.364 BCE], 157d) | |
A reaction: A serious shot by Plato at what identity is. Harte quotes it (125) and shows that 'character' is Gk 'idea', and 'composed' will translate as 'created'. 'Form' links this Platonic passage to Aristotle's hylomorphism. |
15846 | In Parmenides, if composition is identity, a whole is nothing more than its parts [Plato, by Harte,V] |
Full Idea: At the heart of the 'Parmenides' puzzles about composition is the thesis that composition is identity. Considered thus, a whole adds nothing to an ontology that already includes its parts | |
From: report of Plato (Parmenides [c.364 BCE]) by Verity Harte - Plato on Parts and Wholes 2.5 | |
A reaction: There has to be more to a unified identity that mere proximity of the parts. When do parts come together, and when do they actually 'compose' something? |
15849 | Plato says only a one has parts, and a many does not [Plato, by Harte,V] |
Full Idea: In 'Parmenides' it is argued that a part cannot be part of a many, but must be part of something one. | |
From: report of Plato (Parmenides [c.364 BCE], 157c) by Verity Harte - Plato on Parts and Wholes 3.2 | |
A reaction: This looks like the right way to go with the term 'part'. We presuppose a unity before we even talk of its parts, so we can't get into contradictions and paradoxes about their relationships. |
15850 | Anything which has parts must be one thing, and parts are of a one, not of a many [Plato] |
Full Idea: The whole of which the parts are parts must be one thing composed of many; for each of the parts must be part, not of a many, but of a whole. | |
From: Plato (Parmenides [c.364 BCE], 157c) | |
A reaction: This is a key move of metaphysics, and we should hang on to it. The other way madness lies. |
13259 | It seems that the One must be composed of parts, which contradicts its being one [Plato] |
Full Idea: The One must be composed of parts, both being a whole and having parts. So on both grounds the One would thus be many and not one. But it must be not many, but one. So if the One will be one, it will neither be a whole, nor have parts. | |
From: Plato (Parmenides [c.364 BCE], 137c09), quoted by Kathrin Koslicki - The Structure of Objects 5.2 | |
A reaction: This is the starting point for Plato's metaphysical discussion of objects. It seems to begin a line of thought which is completed by Aristotle, surmising that only an essential structure can bestow identity on a bunch of parts. |
22612 | Endurance and perdurance just show the consequences of A or B series time [Ingthorsson] |
Full Idea: Endurance and perdurance are not explanations, but are merely characterisations of persistance with the constraints imposed by either an A or a B view of time. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
A reaction: This is 3-D asnd 4-D objects. A simple and illuminating observation. I love reading broad brush books that make all these simple connections between what seem isolated theories in philosophy. These links are the heart of the subject. |
22625 | Science suggests causal aspects of the constitution and persistance of objects [Ingthorsson] |
Full Idea: There are very obvious causal aspects to the constitution and continued existence of compound entities, especially in light of the scientific image of the world. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 6) | |
A reaction: I like this a lot. He aims to explain constitution and persistance, rather than just describing or characterising them, and causal binding seems the obvious thought. There are still intermittent and distributed objects, like a dismantled clock. |
22620 | If causation involves production, that needs persisting objects [Ingthorsson] |
Full Idea: If causation involves production, then things must endure rather than perdure, because perdurance is incompatible with production, if creation ex nihilo is ruled out. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.10) | |
A reaction: That is, objects must persist over time. Cannot an account of production be given in terms of time-sliceS (or whatever)? 3-D perdurantists obviously have an account of change. He says it also needs the A-series view of time. |
15847 | Two things relate either as same or different, or part of a whole, or the whole of the part [Plato] |
Full Idea: Everything is surely related to everything as follows: either it is the same or different; or, if it is not the same or different, it would be related as part to whole or as whole to part. | |
From: Plato (Parmenides [c.364 BCE], 146b) | |
A reaction: This strikes me as a really helpful first step in trying to analyse the nature of identity. Two things are either two or (actually) one, or related mereologically. |
22636 | Every philosophical theory must be true in some possible world, so the ontology is hopeless [Ingthorsson] |
Full Idea: Possible worlds ontology appears to be plentiful enough to allow every philosophical theory to be true in some world or other, and that is why I cannot consider it an ontologically serious theory. It admits everything and forbids nothing | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.6) | |
A reaction: Nice. Be careful what you wish for. The theory would have to be consistent (unless we also accept impossible worlds). |
22638 | Worlds may differ in various respects, but no overall similarity of worlds is implied [Ingthorsson] |
Full Idea: Even if possible worlds could differ in many different respects, there is no useful way to combine these different respects into one measure of overall comparative similarity. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.7) | |
A reaction: [idea of Michael Moreau 2010] This is an objection to the use of 'close' possible worlds in causation theories. The idea is true in general of the concept of similarity. It makes sense of specific 'respects', but not really of two whole objects. |
21500 | We rely on memory for empirical beliefs because they mutually support one another [Lewis,CI] |
Full Idea: When the whole range of empirical beliefs is taken into account, all of them more or less dependent on memorial knowledge, we find that those which are most credible can be assured by their mutual support, or 'congruence'. | |
From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 334), quoted by Erik J. Olsson - Against Coherence 3.1 | |
A reaction: Lewis may be over-confident about this, and is duly attacked by Olson, but it seems to me roughly correct. How do you assess whether some unusual element in your memory was a dream or a real experience? |
21501 | If we doubt memories we cannot assess our doubt, or what is being doubted [Lewis,CI] |
Full Idea: To doubt our sense of past experience as founded in actuality, would be to lose any criterion by which either the doubt itself or what is doubted could be corroborated. | |
From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 358), quoted by Erik J. Olsson - Against Coherence 3.3.1 | |
A reaction: Obviously scepticism about memory can come in degrees, but total rejection of short-term and clear memories looks like a non-starter. What could you put in its place? Hyper-rationalism? Even maths needs memory. |
6556 | If anything is to be probable, then something must be certain [Lewis,CI] |
Full Idea: If anything is to be probable, then something must be certain. | |
From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 186), quoted by Robert Fogelin - Walking the Tightrope of Reason Intro | |
A reaction: Lewis makes this comment when facing infinite regress problems. It is a very nice slogan for foundationalism, which embodies the slippery slope view. Personally I feel the emotional pull of foundations, but acknowledge the very strong doubts about them. |
21498 | Congruents assertions increase the probability of each individual assertion in the set [Lewis,CI] |
Full Idea: A set of statements, or a set of supposed facts asserted, will be said to be congruent if and only if they are so related that the antecedent probability of any one of them will be increased if the remainder of the set can be assumed as given premises. | |
From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946], 338), quoted by Erik J. Olsson - Against Coherence 2.2 | |
A reaction: This thesis is vigorously attacked by Erik Olson, who works through the probability calculations. There seems an obvious problem without that. How else do you assess 'congruence', other than by evidence of mutual strengthening? |
5828 | Extension is the class of things, intension is the correct definition of the thing, and intension determines extension [Lewis,CI] |
Full Idea: "The denotation or extension of a term is the class of all actual or existent things which the term correctly applies to or names; the connotation or intension of a term is delimited by any correct definition of it." ..And intension determines extension. | |
From: C.I. Lewis (An Analysis of Knowledge and Valuation [1946]), quoted by Stephen P. Schwartz - Intro to Naming,Necessity and Natural Kinds §II | |
A reaction: The last part is one of the big ideas in philosophy of language, which was rejected by Putnam and co. If you were to reverse the slogan, though, (to extension determines intension) how would you identify the members of the extension? |
222 | Only a great person can understand the essence of things, and an even greater person can teach it [Plato] |
Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this. | |
From: Plato (Parmenides [c.364 BCE], 135a) |
225 | The unlimited has no shape and is endless [Plato] |
Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges. | |
From: Plato (Parmenides [c.364 BCE], 137e) |
233 | Some things do not partake of the One [Plato] |
Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole. | |
From: Plato (Parmenides [c.364 BCE], 159d) | |
A reaction: Compare Idea 231 |
231 | Everything partakes of the One in some way [Plato] |
Full Idea: The others are not altogether deprived of the one, for they partake of it in some way. | |
From: Plato (Parmenides [c.364 BCE], 157c) | |
A reaction: Compare Idea 233. |
2062 | The only movement possible for the One is in space or in alteration [Plato] |
Full Idea: If the One moves it either moves spatially or it is altered, since these are the only motions. | |
From: Plato (Parmenides [c.364 BCE], 138b) |
22605 | Humeans describe the surface of causation, while powers accounts aim at deeper explanations [Ingthorsson] |
Full Idea: Humeans attempt to describe causation without any deeper ontological commitments, while powers based accounts attempt to explain why causation occurs in the way it is described. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1) | |
A reaction: Exactly the view I have reached. The Humean view is correct but superficial. A perfect example of my allegiance to Explanatory Empiricism. |
22607 | Time and space are not causal, but they determine natural phenomena [Ingthorsson] |
Full Idea: Time and space are significant determinants of natural phenomena, and yet are not (typically) regarded as causal determinants | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.4) | |
A reaction: I like the word 'determinants'. Metaphysics largely concerns what determines what. I'm struggling to think of examples of this (which he does not give). Decay takes time, but isn't determined by time. Is a light cone a determinant? |
22608 | Casuation is the transmission of conserved quantities between causal processes [Ingthorsson] |
Full Idea: Causal process theories state that causation needs to be understood in terms of causal processes and their interactions, in which conserved quantities are transmitted between causal processes. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.5) | |
A reaction: Sounds a bit circular, but the idea of transmission of something is obviously the main point. I like this idea a lot (because it is so naturalistic), but rarely find it taken seriously. Energy is usually the quantity picked out. |
22614 | Interventionist causal theory says it gets a reliable result whenever you manipulate it [Ingthorsson] |
Full Idea: The core of agency and interventionist theories of causation is that c counts as the cause of e iff E reliably appears and disappears when you manipulate C. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 2.1) | |
A reaction: [C is the type of c; E is the type of e] James Woodward champions this view. Ingthorsson objects that the theory offers no explanation of the appearances and disappearances. You can't manipulate black holes… |
22621 | Causation as transfer only works for asymmetric interactions [Ingthorsson] |
Full Idea: The transference model of causation only works for asymmetric interactions. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.11) | |
A reaction: This is usually the transfer of energy. I liked the theory until I read this. |
22639 | Causal events are always reciprocal, and there is no distinction of action and reaction [Ingthorsson] |
Full Idea: I accept the reciprocity of interactions, and abandon the Agent vs.Patient distinction, so we can no longer talk of the contribution of each as ontologically different types of cause. In interactions, neither action nor reaction can be separated. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 10.3) | |
A reaction: His point is that we are misled by real world happenings, where one component is usually more powerful than the other (such as ball dropped onto a pillow). Modern science endorses his view. Mumford and Anjum seem to agree, and so do I. |
22615 | One effect cannot act on a second effect in causation, because the second doesn't yet exist [Ingthorsson] |
Full Idea: Hobbes implies that a Kim-style event e1 existing at t1 cannot possibly act on an effect e2 at t2, because that effect does not exist until the Agent has worked its effect on the Patient to provoke a change, thus bringing the effect into existence. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.08) | |
A reaction: [Hobbes Elements of Phil 1656 II.IX.1] Ingthorsson says that the Hobbes view is the traditional 'standard' view, that objects (and not events) are the causal relata. A strong objection to events as the causal relata. Realists need objects. |
22616 | Empiricists preferred events to objects as the relata, because they have observable motions [Ingthorsson] |
Full Idea: It is the empiricists' refusal to deal with anything other than observable events that motivated the shift in conception of efficient causation …to influence by an event on another event (one motion on another) rather than by an object on an object. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.10) | |
A reaction: I suppose events supply the necessary activity, whereas objects seem to be too passive for the job - because that's how they look. Ingthorsson persuades that objects are the correct causal relata, for those of us who believe in powers. |
22617 | Science now says all actions are reciprocal, not unidirectional [Ingthorsson] |
Full Idea: It is now accepted as a fact of modern science that unidirectional actions do not exist, and that all interactions are instead thoroughly reciprocal. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 3.10) | |
A reaction: Ingthorsson says this undermines the standard traditional view (Hobbes etc) of Agent and Patient, with A having active powers and P having passive powers. All influences are mutual, it seems. Passive powers are active structures? |
22619 | Causes are not agents; the whole interaction is the cause, and the changed compound is the effect [Ingthorsson] |
Full Idea: By abandoning the standard view that causes are ‘extrinsic motive Agents’, an idea from pre-Newtonian physics, we are free to conceive of the interaction as a whole as the cause, and the change in the compound whole of interacting things as the effect. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.06) | |
A reaction: Ingthorsson persuasively presents this as the correct account, as understood by modern science. It is not cause-then-effect. It is kerfuffle, then aftermath. |
22635 | People only accept the counterfactual when they know the underlying cause [Ingthorsson] |
Full Idea: I doubt that anyone will accept any counterfactual as true unless they believe they know the underlying causality. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.3) | |
A reaction: Correct. Almost any example will support it. Compare coincidences and true causes. |
22634 | Counterfactuals don't explain causation, but causation can explain counterfactuals [Ingthorsson] |
Full Idea: I cannot identify any prima facie reason to think that causation can be explained in counterfactual terms, but plenty to think that causation can explain counterfactuals. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.1) | |
A reaction: Love it. Treating causation as counterfactual dependency is hopelessly superficial. What is the reality that is involved? He cites the second law of motion. |
22637 | Counterfactual theories are false in possible worlds where causation is actual [Ingthorsson] |
Full Idea: if there are worlds where there are causal powers and/or lawful connections, then they are worlds in which the counterfactual theory of causation is false, because there causes produce the effects, regardless of any possible world. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 9.6) | |
A reaction: A nice modern instance of turning the tables. Come to think of it, possible worlds theories are just asking for that. Are there possible worlds in which there are no other possible worlds? Or the possible worlds are inaccessible? |
22624 | A cause can fail to produce its normal effect, by prevention, pre-emption, finks or antidotes [Ingthorsson] |
Full Idea: Counterexamples involving prevention and/or interference have come to be roughly divided into four main categories: (i) prevention, (ii) pre-emption, (iii) finks and (iv) antidotes. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 5.3) | |
A reaction: These are the reasons why necessity is denied in causation. i) is in the initial circumstances, ii) is another cause getting there first, iii) is a defusing action in the agent, iv) is a defusing action in the patient. No necessity if one is possible. |
22622 | Any process can go backwards or forwards in time without violating the basic laws of physics [Ingthorsson] |
Full Idea: Because it makes no difference to exchange the time variable t with its contrary -t, in the fundamental laws of physics, any process can be described as going either backwards or forwards in time, without violating those laws. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.13) | |
A reaction: A few philosophers read a lot into this, but I don't. The inverse scenario may not breach the laws of physics, but it does involve time going backwards, which I think we can skip for now. Entropy would be interesting. Can information flow backwards? |
22618 | In modern physics the first and second laws of motion (unlike the third) fail at extremes [Ingthorsson] |
Full Idea: While the first and second laws of motion are known to fail in the domain of very fast-moving and massive objects (i.e. where relativity deviates from classical mechanics) as well as in the quantum realm, the third law is still assumed to hold good. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 4.04) | |
A reaction: This implies a universal status for the third law (equal and opposite reactions), which the other two lack. Ingthorsson sees this as crucial for our understanding of causation. |
22630 | If particles have decay rates, they can't really be elementary, in the sense of indivisible [Ingthorsson] |
Full Idea: We may wonder whether the fact that physics has calculated (and for some, confirmed) the decay rate of elementary particles can be a reason to think that they cannot really be ‘elementary’ in the philosophical sense of ‘indivisible’. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 7.6) | |
A reaction: I don't think anything can ever conclusively be labelled as 'elementary', but this idea offers a reason for doubting whether a candidate particle is so basic. Does decay imply having parts? |
22610 | It is difficult to handle presentism in first-order logic [Ingthorsson] |
Full Idea: Contemporary philosophers are not comfortable with presentism, because it is difficult to deal with presentism in the language of first-order predicate logic. | |
From: R.D. Ingthorsson (A Powerful Particulars View of Causation [2021], 1.8) | |
A reaction: Presumable that logic relies on objects which endure through time, or at least have a past. Second-order logic is better able to deal with processes, which only exist in the present, but nevertheless have an integral past and future. ? |
234 | We couldn't discuss the non-existence of the One without knowledge of it [Plato] |
Full Idea: There must be knowledge of the one, or else not even the meaning of the words 'if the one does not exist' would be known. | |
From: Plato (Parmenides [c.364 BCE], 160d) |
