| 14888 | Wisdom prevents us from being ruled by the moment [Nietzsche] |
| Full Idea: The most important thing about wisdom is that it prevents human beings from being ruled by the moment. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [25]) |
| 14863 | Unlike science, true wisdom involves good taste [Nietzsche] |
| Full Idea: Inherent in wisdom [sophia] is discrimination, the possession of good taste: whereas science, lacking such a refined sense of taste, gobbles up anything that is worth knowing. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [086]) | |
| A reaction: This is blatantly unfair to science, which may lack 'taste', but at least prefers deep theories with wide-ranging explanatory power to narrow local theories. Maybe the line across the philosophical community is the one picking out those with taste? |
| 14890 | Suffering is the meaning of existence [Nietzsche] |
| Full Idea: Suffering is the meaning of existence. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 32 [67]) | |
| A reaction: This doesn't mean that he is advocating suffering. The context of his remark is that the pursuit of truth involves suffering. |
| 14861 | Philosophy ennobles the world, by producing an artistic conception of our knowledge [Nietzsche] |
| Full Idea: Philosophy is indispensable for education because it draws knowledge into an artistic conception of the world, and thereby ennobles it. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [052]) | |
| A reaction: I take this to be an unusual way of saying that philosophy aims at the unification of knowledge, which is roughly my own view. It has hard for us to keep believing that life could be 'ennobled'. |
| 14885 | The first aim of a philosopher is a life, not some works [Nietzsche] |
| Full Idea: The philosopher's product is his life (first, before his works). It is his work of art. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [205]) |
| 14887 | You should only develop a philosophy if you are willing to live by it [Nietzsche] |
| Full Idea: One should have a philosophy only to the extent that one is capable of living according to this philosophy: so that everything does not become mere words. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [17]) |
| 14889 | Philosophy is pointless if it does not advocate, and live, a new way of life [Nietzsche] |
| Full Idea: As long as philosophers do not muster the courage to advocate a lifestyle structured in an entirely different way and demonstrate it by their own example, they will come to nothing. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 31 [10]) | |
| A reaction: This is a pretty tough requirement for the leading logicians and metaphysicians of our day, but they must face their marginality. The public will only be interested in philosophers who advocate new ways of living. |
| 14862 | Philosophy is more valuable than much of science, because of its beauty [Nietzsche] |
| Full Idea: The reason why unprovable philosophizing still has some value - more value, in fact, than many a scientific proposition - lies in the aesthetic value of such philosophizing, that is, in its beauty and sublimity. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [076]) | |
| A reaction: I am increasingly inclined to agree. I love wide-ranging and ambitious works of metaphysics, each of which is a unique creation of the human intellect (and with which no other individual will ever entirely agree). A great short paper is also beautiful. |
| 14878 | It would better if there was no thought [Nietzsche] |
| Full Idea: It would be better if thought did not exist at all. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [004]) |
| 14881 | Why do people want philosophers? [Nietzsche] |
| Full Idea: Why do human beings even want philosophers? | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [019]) | |
| A reaction: It is not clear, of course, that they do want philosophers. The standard attitude to them seems to be a mixture of contempt and fear. |
| 14876 | Philosophy is always secondary, because it cannot support a popular culture [Nietzsche] |
| Full Idea: It is not possible to base a popular culture on philosophy. Thus, with regard to culture, philosophy never can have primary, but always only secondary, significance. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 23 [14]) | |
| A reaction: It is the brilliance of Christianity as a set of ideas that it is simple enough to found a popular culture. A complex theology would make that impossible. Luther brought it back to its roots, when the priesthood lost touch with the people. |
| 14912 | There is no test for metaphysics, except devising alternative theories [Ladyman/Ross] |
| Full Idea: The metaphysician has no test for the truth of her beliefs except that other metaphysicians can't think of obviously superior alternative beliefs. (They can always think of possibly superior ones, in profusion). | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.7) | |
| A reaction: [they cite Van Fraassen for this view] At least this seems to concede that some metaphysical views can be rejected by the observation of beliefs that are superior. Almost everyone has rejected Lewis on possible worlds for this reason. |
| 14904 | Metaphysics builds consilience networks across science [Ladyman/Ross] |
| Full Idea: Metaphysics is the enterprise of critically elucidating consilience networks across the sciences. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.3) | |
| A reaction: I don't disagree with this. The issue, I think, is how abstract you are prepared to go. At high levels of abstraction, it is very hard to keep in touch with the empirical research. There are truths, though, at that high level. It is clearest in logic. |
| 14907 | Progress in metaphysics must be tied to progress in science [Ladyman/Ross] |
| Full Idea: To the extent that metaphysics is closely motivated by science, we should expect to make progress in metaphysics iff we can expect to make progress in science. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.3) | |
| A reaction: To defer to and respect science does not necessitate that metaphysics cannot do independent work. I take there to be truths at a high-level of abstraction that are independent of the physical sciences, just as there are truths of chess or economics. |
| 14908 | Metaphysics must involve at least two scientific hypotheses, one fundamental, and add to explanation [Ladyman/Ross] |
| Full Idea: Principle of Naturalist Closure: A serious metaphysical claim must involve at least two scientific hypotheses, at least one from fundamental physics, and explain more than what the two hypotheses explain separately. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.3) | |
| A reaction: [compressed, from their longer qualified version] The idea that metaphysics should add to explanation is close to my heart. I am musing over whether essences add to explanation, which would be total anathema to Ladyman and Ross. |
| 14910 | Some science is so general that it is metaphysical [Ladyman/Ross] |
| Full Idea: Some scientific propositions are sufficiently general as themselves to be metaphysical. Our notion of metaphysics is thus recursive, and requires no attempt to identify a boundary between metaphysical and scientific propositions. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.5 n45) | |
| A reaction: Note that this still leaves room for some metaphysics which is not science, though see Idea 14904 for their views on that. |
| 14940 | Cutting-edge physics has little to offer metaphysics [Ladyman/Ross] |
| Full Idea: There is little positive by way of implications for metaphysics that we can adduce from cutting-edge physics. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.2) | |
| A reaction: My personal suspicion is that this will always be the case, even though there may be huge advances in physics, and I offer that as a reason why metaphysicians do not (pace Ladyman and Ross) need to study physics. They grasp 'negative' lessons. |
| 14945 | The aim of metaphysics is to unite the special sciences with physics [Ladyman/Ross] |
| Full Idea: The demand to unify the special sciences with physics is, according to us, the motivation for having any metaphysics at all. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.1) | |
| A reaction: The crunch question is whether metaphysicians are allowed to develop their own concepts for this task, or whether they can only make links between the concepts employed by the scientists. I vote for the former. |
| 14898 | Modern metaphysics pursues aesthetic criteria like story-writing, and abandons scientific truth [Ladyman/Ross] |
| Full Idea: The criteria of adequacy for metaphysics have come apart from anything to do with truth. Rather they are internal and peculiar to philosophy, they are semi-aesthetic, and they have more in common with the virtues of story-writing than with science. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.1) | |
| A reaction: Part of a sustained polemic against contemporary analytic metaphysics. I love metaphysics, but they may be right. Writers like Sider, Fine, Lowe, Lewis, Stalnaker, Kripke, Armstrong, Dummett seem to tell independent stories, that really are works of art. |
| 14860 | Kant has undermined our belief in metaphysics [Nietzsche] |
| Full Idea: In a certain sense, Kant's influence was detrimental; for the belief in metaphysics has been lost. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [028]) | |
| A reaction: As I understand it, there are two interpretations of Kant, one of which is fairly thoroughly anti-metaphysical, and another which is less so. Also one path leads to idealism and the other doesn't, but I need to research that. |
| 14899 | Why think that conceptual analysis reveals reality, rather than just how people think? [Ladyman/Ross] |
| Full Idea: Why should we think that the products of conceptual analysis reveal anything about the deep structure of reality, rather than telling us about how some class of people think about and categorize reality? | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.2) | |
| A reaction: One line, associated with Jackson, is that analysis tells you not about reality, but about what to make of your experiences of reality when you have them. It would be a foolish scientist who paid no attention to his or her conceptual scheme. |
| 14936 | A metaphysics based on quantum gravity could result in almost anything [Ladyman/Ross] |
| Full Idea: We cannot say what the metaphysical implications of quantum gravity are, but they range from eleven dimensions to two, from continuous fundamental structure to a discrete one, and from universal symmetries to no symmetries. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.2) | |
| A reaction: I offer this observation as a good reason for doubting whether the project of building our metaphysics directly onto our fundamental physics has much prospect of success. Quantum gravity is the unified theory they are all hoping for. |
| 14859 | If philosophy controls science, then it has to determine its scope, and its value [Nietzsche] |
| Full Idea: The philosophy that is in control of science must also consider the extent to which science should be allowed to develop; it must determine its value! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [024]) |
| 14905 | The supremacy of science rests on its iterated error filters [Ladyman/Ross] |
| Full Idea: The epistemic supremacy of science rests on repeated iteration of institutional error filters. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.3) | |
| A reaction: You could add repeated iteration of institutional error filters to journals about astrology, but it wouldn't thereby acquire epistemic supremacy. It is the tangible nature of the evidence which bestows the authority. |
| 14897 | We should abandon intuitions, especially that the world is made of little things, and made of something [Ladyman/Ross] |
| Full Idea: Abandoning intuitions is usually regarded as a cost rather than a benefit. By contrast, as naturalists we are not concerned with preserving intuitions at all (especially that the world is composed of little things, and that it must be made of something). | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.1) |
| 14880 | Logic is just slavery to language [Nietzsche] |
| Full Idea: Logic is merely slavery in the fetters of language. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [008]) | |
| A reaction: I don't think I agree with this, but I still like it. |
| 14943 | Maybe mathematical logic rests on information-processing [Ladyman/Ross] |
| Full Idea: It is claimed that mathematical logic can be understood in terms of information-processing. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.5) | |
| A reaction: [They cite Chaitin 1987] I don't understand how this would work, but it is still worth quoting. This would presumably make logic rest on processes rather than on entities. I quite like that. |
| 16588 | I prefer a lack of form to mean non-existence, than to think of some quasi-existence [Augustine] |
| Full Idea: I sooner judged that what lacks all form does not exist, than thought of as something in between form and nothing, neither formed nor nothing, unformed and next to nothing. | |
| From: Augustine (Confessions [c.398], XII.6), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 03.1 | |
| A reaction: Scholastics were struck by the contrast between this remark, and the remark of Averroes (Idea 16587) that prime matter was halfway existence. Their two great authorities disagreed! This sort of thing stimulated the revival of metaphysics. |
| 14948 | To be is to be a real pattern [Ladyman/Ross] |
| Full Idea: To be is to be a real pattern. ....Real patterns carry information about other real patterns. ...It's patterns all the way down. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.4) | |
| A reaction: I've plucked these bleeding from context, but they are obviously intended as slogans. Is there pattern 'inside' an electron? Are electrons all exterior? |
| 14942 | Only admit into ontology what is explanatory and predictive [Ladyman/Ross] |
| Full Idea: We reject any grounds other than explanatory and predictive utility for admitting something into our ontology. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.3) | |
| A reaction: Now you are talking. This is something like my thesis (which I take to be Aristotelian) - that without the drive for explanation we wouldn't even think of metaphysics, and so metaphysics should be understood in that light. |
| 14947 | Any process can be described as transfer of measurable information [Ladyman/Ross] |
| Full Idea: Reference to transfer of some (in principle) quantitatively measurable information is a highly general way of describing any process. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.3) | |
| A reaction: That does not, of course, mean that that is what a process is. A waterfall is an archetypal process, but it is a bit more than a bunch of information. Actually its complexity may place its information beyond measurement. |
| 14941 | We say there is no fundamental level to ontology, and reality is just patterns [Ladyman/Ross] |
| Full Idea: The tentative metaphysical hypothesis of this book, which is open to empirical falsification, is that there is no fundamental level, that the real patterns criterion of reality is the last word in ontology. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.3) | |
| A reaction: I wouldn't hold your breath waiting for the empirical falsification to arrive (or vanish). Their commitment to real patterns (or structures) leaves me a bit baffled. |
| 14869 | If some sort of experience is at the root of matter, then human knowledge is close to its essence [Nietzsche] |
| Full Idea: If pleasure, displeasure, sensation, memory, reflex movements are all part of the essence of matter, then human knowledge penetrates far more deeply into the essence of things. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [161]) | |
| A reaction: I don't think Nietzsche is thinking of monads at this point, but his idea certainly applies to them. Leibniz rested his whole theory on the close analogy between how minds work and how matter must also work. |
| 10493 | If concrete is spatio-temporal and causal, and abstract isn't, the distinction doesn't suit physics [Ladyman/Ross] |
| Full Idea: It is said that concrete objects have causal powers while abstract ones do not, or that concrete objects exist in space and time while abstract ones do not, but these categories seem crude and inappropriate for modern physics. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.6) | |
| A reaction: I don't find this convincing. He gives example of peculiar causation, but I don't believe modern physics proposes any entities which are totally acausal and non-spatiotemporal. Maybe the distinction needs a defence. |
| 14934 | Concrete and abstract are too crude for modern physics [Ladyman/Ross] |
| Full Idea: The categories of concrete and abstract seem crude and inappropriate for modern physics. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.6) | |
| A reaction: They don't persuade me of this idea. At some point physicists need to decide the ontological status of the basic stuffs they are investigating. I'll give them a thousand years, and then I want an answer. Do they only deal in 'ideal' entities? |
| 22979 | Three main questions seem to be whether a thing is, what it is, and what sort it is [Augustine] |
| Full Idea: I am told that I can ask three sorts of questions - whether a thing is, what it is, and what sort it is. | |
| From: Augustine (Confessions [c.398], X.10) | |
| A reaction: This seems to be a very Aristotelian approach. I am pleased to see that what it is and what sort it is are not conflated. The first one must be its individual essence, and the second its generic essence. |
| 14909 | Physicalism is 'part-whole' (all parts are physical), or 'supervenience/levels' (dependence on physical) [Ladyman/Ross] |
| Full Idea: There is part-whole physicalism, that everything is exhausted by basic constituents that are themselves physical, or supervenience or levels physicalism, that the putatively non-physical is dependent on the physical. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.3) | |
| A reaction: The cite Hüttemann and Papineau 2005. I am not convinced by this distinction. Ladyman and Ross oppose the first one. I'm thinking the second one either collapses into the first one, or it isn't physicalism. Higher levels are abstractions. |
| 14926 | Relations without relata must be treated as universals, with their own formal properties [Ladyman/Ross] |
| Full Idea: The best sense that can be made of a relation without relata is the idea of a universal. Thus the relation 'larger than' has formal properties that are independent of the contingencies of their instantiation. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4) | |
| A reaction: Russell was keen on the idea that relations are universals, and presumably for this reason. I struggle to grasp uninstantiated but nevertheless real 'greater than' relations. They are abstractions from things, not separate universals. |
| 14929 | A belief in relations must be a belief in things that are related [Ladyman/Ross] |
| Full Idea: Many philosophers say that one cannot intelligibly subscribe to the reality of relations unless one is also committed to the fact of some things that are related. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.5) | |
| A reaction: Ladyman and Ross try to argue against this view, but the idea makes a strong impression on me. Your ontology seems to be rather strange if you have a set of structural relations that await things to slot into the structure. |
| 14925 | The normal assumption is that relations depend on properties of the relata [Ladyman/Ross] |
| Full Idea: The idea that there could be relations which do not supervene on the properties of their relata runs counter to a deeply entrenched way of thinking. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4) | |
| A reaction: Ladyman and Ross are trying to defend the idea of 'structure' which is independent of the objects that occupy the nodes of the structure. Tricky. |
| 14931 | That there are existent structures not made of entities is no stranger than the theory of universals [Ladyman/Ross] |
| Full Idea: Is the main metaphysical idea we propose (of existent structures that are not composed out of more basic entities) any more obscure or bizarre than the instantiation relation in the theory of universals? | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.5) | |
| A reaction: No, it is not more bizarre than that, but that isn't much of a reason to believe their theory. See Idea 8699, and many ideas about structure in mathematics. Ladyman and Ross still smack of platonism, even if they are rooted in particle physics. |
| 14932 | Causal essentialism says properties are nothing but causal relations [Ladyman/Ross] |
| Full Idea: Causal essentialism is the doctrine that the causal relations that properties bear to other properties exhaust their natures. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.5 n50) | |
| A reaction: [They cite Shoemaker, Mumford and Bird for this] Personally I don't see this view as offering relations as fundamental. The whole point is to explain everything. The only plausible primitive notion is of a power - which then generates the relations. |
| 14920 | If science captures the modal structure of things, that explains why its predictions work [Ladyman/Ross] |
| Full Idea: If theorists are able sometimes to capture the objective modal structure of the world then it is no surprise that successful novel prediction sometimes works. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.4) | |
| A reaction: This is a rather important idea, particularly for my approach. I say we should demand more explanations, and explanations of successful prediction are far from obvious in a regularity account of nature. |
| 14952 | Things are constructs for tracking patterns (and not linguistic, because animals do it) [Ladyman/Ross] |
| Full Idea: Individual things are constructs built for second-best tracking of real patterns. They are not necessarily linguistic constructions, since some non-human animals almost certainly cognitively construct them. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5) | |
| A reaction: Delighted to see animals making an appearance. Fans of language-based metaphysics please note. If they are fictional constructs, why do they do such a good job of tracking? What generates the 'superficial' appearance that there are objects? |
| 14950 | Maybe individuation can be explained by thermodynamic depth [Ladyman/Ross] |
| Full Idea: Scientists have developed principles for understanding individuation in terms of the production of thermodynamic depth. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5) | |
| A reaction: [They cite J.Collier for this view] Interesting, even though I don't really understand 'thermodynamic depth'. Ladyman and Ross reject it, but there is a whiff of a theory of individuation from within physics. |
| 14927 | Physics seems to imply that we must give up self-subsistent individuals [Ladyman/Ross] |
| Full Idea: There is growing convergence among philosophers of physics that physics motivates abandonment of a metaphysics that posits fundamental self-subsistent individuals. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4) | |
| A reaction: They cite fermions as an example, which only seem to be given an identity by the relations into which they enter. It is a bit cheeky to simultaneously offer this idea, and despise van Inwagen and Merricks for the same object nihilism. |
| 14944 | There is no single view of individuals, because different sciences operate on different scales [Ladyman/Ross] |
| Full Idea: There is no single account of what individuals there are because, we argue, the special sciences may disagree about the bounds and status of individuals since they describe the world at different scales. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.8) | |
| A reaction: This seems to deny that nature has actual joints, and so seems to me to be a form of anti-realism (which they would deny). Why shouldn't there be a single view which unites all of these special sciences? |
| 14946 | There are no cats in quantum theory, and no mountains in astrophysics [Ladyman/Ross] |
| Full Idea: At the quantum scale there are no cats; at scales appropriate for astrophysics there are no mountains. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.2) | |
| A reaction: I don't find this convincing. Since cats are made of quantised entities, they do exist in that world, but are of little interest when trying to understand it. Similarly, astrophysicists hardly deny the existence of mountains! |
| 14928 | Things are abstractions from structures [Ladyman/Ross] |
| Full Idea: Individual things are locally focused abstractions from modal structure. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.4) | |
| A reaction: I am a fan of the role of abstraction in our understanding of the world, despite my limited progress in trying to explicate the idea. I can't decide whether or not there are any things. A bit basic, that! |
| 14892 | The idea of composition, that parts of the world are 'made of' something, is no longer helpful [Ladyman/Ross] |
| Full Idea: It is no longer helpful to conceive of either the world, or particular systems of the world that we study in partial isolation, as 'made of' anything at all. …Our target here is the metaphysical idea of composition. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.1) | |
| A reaction: This is argued by them from the point of view of fundamental physics as the provider of our basic metaphysics about the world. Personally I really really want to know what electrons are made of, but I know no one is going to tell me. They may even laugh. |
| 14949 | A sum of things is not a whole if the whole does not support some new generalisation [Ladyman/Ross] |
| Full Idea: A nostril, a city and a trumpet solo is not a real pattern, because identification of it supports no generalisations not supported by identification of the three conjuncts considered separately. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.4) | |
| A reaction: This is a nice try at offering a criterion for unity, but I doubt whether it will work, because an ingenious person could come up with wild generalisations. These three combined make possible a charming new line of poetry. |
| 14951 | We treat the core of a pattern as an essence, in order to keep track of it [Ladyman/Ross] |
| Full Idea: We focus on diagnostic features of real patterns that we can treat as 'core', which reliably predict that our attention is still tracking the same real pattern. These are Locke's 'essence of particulars', or Putnam's 'hidden structures'. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5) | |
| A reaction: They seemed to be ashamed of themselves for proposing this, and call it a 'second-best' epistemological device. They seem to imply that they are useful fictions, but why shouldn't the hidden structures be real? They might both identify and explain. |
| 14958 | A continuous object might be a type, with instances at each time [Ladyman/Ross] |
| Full Idea: Why should not 'Napoleon' be a type, of which 'Napoleon in 1805' and 'Napoleon in 1813' are instances? | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 5.6) | |
| A reaction: That is very nice. That might be a view that suits presentism, where the timed instances never co-exist, and so have the sort of abstract existence that we associate with types. |
| 14903 | Quantum mechanics seems to imply single-case probabilities [Ladyman/Ross] |
| Full Idea: Quantum mechanics seems to imply single-case probabilities. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.3) | |
| A reaction: I know they keep telling us about such things, but I remain cautious. I think all the physicists have done is delved a bit deeper into something they don't understand. |
| 14923 | In quantum statistics, two separate classical states of affairs are treated as one [Ladyman/Ross] |
| Full Idea: In quantum statistics, what would be regarded as two possible states of affairs classically is treated as one possible state of affairs. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.1) |
| 14875 | Belief matters more than knowledge, and only begins when knowledge ceases [Nietzsche] |
| Full Idea: The human being starts to believe when he ceases to know. …Knowledge is not as important for the welfare of human beings as is belief. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 21 [13]) | |
| A reaction: The first idea is now associated with Williamson (and Hossack). The second is something like the pragmatic view of belief espoused by Ramsey. |
| 14866 | It always remains possible that the world just is the way it appears [Nietzsche] |
| Full Idea: Against Kant we can still object, even if we accept all his propositions, that it is still possible that the world is as it appears to us. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [125]) | |
| A reaction: This little thought at least seems to be enough to block the slide from phenomenalism into total idealism. The idea that direct realism can never be ruled out, even if it is false, is very striking. |
| 14955 | Rats find some obvious associations easier to learn than less obvious ones [Ladyman/Ross] |
| Full Idea: Contrary to early behaviourist dogma, associations are not all equally learnable. Rats learn to associate eating with nausea, and a flash with a shock, much more easily than either complementary pairing. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 5.2) | |
| A reaction: That looks like an argue for some sort of innate knowledge, but experiments to disentangle eating from nausea must be rather hard to set up. |
| 14918 | The doctrine of empiricism does not itself seem to be empirically justified [Ladyman/Ross] |
| Full Idea: If to be an empiricist is to believe that 'experience is the sole source of information about the world', the problem is that this does not itself seem to be justifiable by experience. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.3.1) | |
| A reaction: [The quotation is from Van Fraassen 1985 p.253] This is the classic 'turning the tables' move in argument, invented by the Greeks. It is hard to offer anything other than intuition in the first move of any metaphysical theory. |
| 14891 | There is no reason to think our intuitions are good for science or metaphysics [Ladyman/Ross] |
| Full Idea: There is no reason to imagine that our habitual intuitions and inferential responses are well designed for science or for metaphysics. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.1) |
| 22980 | Memory contains innumerable principles of maths, as well as past sense experiences [Augustine] |
| Full Idea: The memory contains the innumerable principles and laws of numbers and dimensions. None of these can have been conveyed to me by the bodily senses. | |
| From: Augustine (Confessions [c.398], X.12) | |
| A reaction: Even if you have a fairly empirical view of the sources of mathematics (a view with which I sympathise), it must by admitted that our endless extrapolations from the sources also reside in memory. So we remember thoughts as well as experiences. |
| 22983 | We would avoid remembering sorrow or fear if that triggered the emotions afresh [Augustine] |
| Full Idea: If we had to experience sorrow or fear every time that we mentioned these emotions, no one would be willing to speak of them. | |
| From: Augustine (Confessions [c.398], X.14) | |
| A reaction: Remembering the death of a loved one can trigger fresh grief, but remembering their dangerous illness from which they recovered no longer contains the feeling of fear. |
| 22981 | Mind and memory are the same, as shown in 'bear it in mind' or 'it slipped from mind' [Augustine] |
| Full Idea: The mind and the memory are one and the same. We even call the memory the mind, for when we tell a person to remember something, we tell them to 'bear this in mind', and when we forget something 'it slipped out of my mind'. | |
| From: Augustine (Confessions [c.398], X.14) | |
| A reaction: This idea has become familiar in modern neuroscience, I think, presumably because we do not find distinct types of neurons for consciousness and for memory. |
| 22977 | I can distinguish different smells even when I am not experiencing them [Augustine] |
| Full Idea: I can distinguish the scent of lilies from that of violets, even though there is no scent at all in my nostrils. | |
| From: Augustine (Confessions [c.398], X.08) | |
| A reaction: Augustine has a nice introspective account of how we experience memory, and identifies lots of puzzling features. I know I can identify the smell of vinegar, but I can't bring it to mind, the way I can the appearance of roses. |
| 22982 | Why does joy in my mind make me happy, but joy in my memory doesn't? [Augustine] |
| Full Idea: How can it be that my mind can be happy because of the joy that is in it, and yet my memory is not sad by reason of the sadness that is in it? | |
| From: Augustine (Confessions [c.398], X.14) | |
| A reaction: This seems to contradict his thought in Idea 22981, that memory and mind are the same. Recall seems to be a part of consciousness which is not fully wired up to the rest of the mind. |
| 14872 | Our knowledge is illogical, because it rests on false identities between things [Nietzsche] |
| Full Idea: Every piece of knowledge that is beneficial to us involves an identification of nonidentical things, of things that are similar, which means that it is essentially illogical. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [236]) | |
| A reaction: I take the thought to be that no two tigers are alike, but we call them all 'tigers' and merge them into a type, and then all our knowledge is based on this distortion. A wonderful idea. I love particulars You should love particulars. |
| 14879 | The most extreme scepticism is when you even give up logic [Nietzsche] |
| Full Idea: Even skepticism contains a belief: the belief in logic. The most extreme position is hence the abandoning of logic. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [008]) | |
| A reaction: Some might say that flirting with non-classical logic (as in Graham Priest) is precisely travelling down this road. You could also be sceptical about meaning in language, so you couldn't articulate your abandonment of logic. |
| 14915 | The theory of evolution was accepted because it explained, not because of its predictions [Ladyman/Ross] |
| Full Idea: Darwin's theory of evolution was accepted by the scientific community because of its systematizing and explanatory power, and in spite of its lack of novel predictive success. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.1.3) | |
| A reaction: I am keen on the centrality of explanation to all of our thinking, metaphysical as well as physical, so I like this one. In general I like accounts of science that pay more attention to biology, and less to physics. |
| 14916 | What matters is whether a theory can predict - not whether it actually does so [Ladyman/Ross] |
| Full Idea: We suggest a modal account of novel prediction. That a theory could predict some unknown phenomenon is what matters, not whether it actually did so predict. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.1.3) | |
| A reaction: They also emphasise predicting new types of thing, rather than particular items. Some theories are powerful on explanation, but not so concerned with prediction. See Idea 14915. |
| 14922 | The Ramsey sentence describes theoretical entities; it skips reference, but doesn't eliminate it [Ladyman/Ross] |
| Full Idea: It is a mistake to think that the Ramsey sentence allows us to eliminate theoretical entities, for it still states that they exist. It is just that they are referred to not directly, by means of theoretical terms, but by description. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.4.1) |
| 14921 | The Ramsey-sentence approach preserves observations, but eliminates unobservables [Ladyman/Ross] |
| Full Idea: If one replaces the assertions of a first-order theory with its Ramsey sentence (giving a quantified predicate variable for a theoretical term), the observational consequences are carried over, but direct reference to unobservables is eliminated. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.4.1) | |
| A reaction: Thus this rewriting of theories is popular with empiricists, and this draws attention to the way you can change the ontological commitments simply by paraphrase. ...However, see Idea 14922. |
| 14953 | Induction is reasoning from the observed to the unobserved [Ladyman/Ross] |
| Full Idea: Induction is any form of reasoning that proceeds from claims about observed phenomena to claims about unobserved phenomena. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5) | |
| A reaction: Most accounts of induction seem to imply that they lead to generalisations, rather than just some single unobserved thing. This definition is in line with David Lewis's. |
| 14914 | Inductive defences of induction may be rule-circular, but not viciously premise-circular [Ladyman/Ross] |
| Full Idea: The inductive defence of induction may be circular but not viciously so, because it is rule circular (defending the rule being used) but not premise circular (where the conclusion is in one of the premises). | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.1.2) | |
| A reaction: [They cite Braithwaite 1953 and Carnap 1952 for this] This strikes me as clutching at straws, when the whole procedure of induction is inescapably precarious. It is simply all we have available. |
| 14913 | We explain by deriving the properties of a phenomenon by embedding it in a large abstract theory [Ladyman/Ross] |
| Full Idea: Theoretical explanation is the derivation of the properties of a relatively concrete and observable phenomenon by means of an embedding into some larger, relatively abstract and unobservable theoretical structure. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 2.1.1) | |
| A reaction: [they are citing Michael Friedman 1981 p.1] This sounds like covering law explanation, but the theoretical structure will be a set of intersecting laws, rather than a single law. How do you explain the theoretical structure? |
| 14873 | If we find a hypothesis that explains many things, we conclude that it explains everything [Nietzsche] |
| Full Idea: The feeling of certainty is the most difficult to develop. Initially one seeks explanation: if a hypothesis explains many things, we draw the conclusion that it explains everything. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [238]) | |
| A reaction: As so often, a wonderful warning from Nietzsche to other philosophers. They love to latch onto a Big Idea, and offer it as the answer to everything (especially, dare I say it, continental philosophers). |
| 22978 | Memory is so vast that I cannot recognise it as part of my mind [Augustine] |
| Full Idea: The memory is a vast immeasurable sanctuary. It is part of my nature, but I cannot understand all that I am. Hence the mind is too narrow to contain itself entirely. Is the other part outside of itself, and not within it? How then can it be a part? | |
| From: Augustine (Confessions [c.398], X.08) | |
| A reaction: He seems to understand the mind as entirely consisting of consciousness. Nevertheless, this seems to be the first inklings of the modern externalist view of the mind. |
| 14868 | Our primary faculty is perception of structure, as when looking in a mirror [Nietzsche] |
| Full Idea: The primary faculty seems to me to be the perception of structure, that is, based upon the mirror. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [153]) | |
| A reaction: The point about the mirror makes this such an intriguingly original idea. Personally I like very much the idea that structure is our prime perception. See Sider 2011 on structure. |
| 14930 | Maybe the only way we can think about a domain is by dividing it up into objects [Ladyman/Ross] |
| Full Idea: Speculating cautiously about psychology, it is possible that dividing a domain up into objects is the only way we can think about it. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.5) | |
| A reaction: Typical physicists - they speculate about psychology instead of studying it. Have they no respect for science? Neverthless my speculative psychology agrees with theirs. This fact may well be the key to all of metaphysics. |
| 14870 | We experience causation between willing and acting, and thereby explain conjunctions of changes [Nietzsche] |
| Full Idea: The only form of causality of which we are aware is that between willing and acting - we transfer this to all things, and thereby explain the relationship between two changes that always occur together. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [209]) | |
| A reaction: This is a rather Humean view, of projecting our experience onto the world, but it may be that we really are experiencing real causation, just as it occurs between insentiate things. |
| 22984 | Without memory I could not even speak of myself [Augustine] |
| Full Idea: I do not understand the power of memory that is in myself, although without it I could not even speak of myself. | |
| From: Augustine (Confessions [c.398], X.16) | |
| A reaction: Even if the self is not identical with memory, this idea seems to establish that memory is an essential aspect of the self. This point is neglected by those who see the self as an entity (the 'soul pearl') which persists through all experience. |
| 14939 | Two versions of quantum theory say that the world is deterministic [Ladyman/Ross] |
| Full Idea: In the Bohm version of quantum theory, and the Everett approach, the world comes out deterministic after all. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.2) | |
| A reaction: This is just in case anyone wants to trumpet the idea that quantum theory has established indeterminism. It is particularly daft to think that quantum indeterminacy makes free will possible (or even actual). |
| 5982 | If the future does not exist, how can prophets see it? [Augustine] |
| Full Idea: How do prophets see the future, if there is not a future to be seen? | |
| From: Augustine (Confessions [c.398], XI.17) | |
| A reaction: The answer, I suspect, is that prophets can't see the future. The prospect that the future already exists would seem to saboutage human freedom and responsibility, and point to Calvinist predestination, and even fatalism. |
| 14867 | It is just madness to think that the mind is supernatural (or even divine!) [Nietzsche] |
| Full Idea: To view 'spirit', the product of the brain, as supernatural. Even to deify it. What madness! | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [127]) | |
| A reaction: When I started philolosophy I was obliged to take mind-body dualism very seriously, but I have finally managed to drag myself to the shores of this lake of madness, where Nietzsche awaited with a helping hand. |
| 14911 | Science is opposed to downward causation [Ladyman/Ross] |
| Full Idea: When someone pronounces for downward causation they are in opposition to science. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.6 n54) | |
| A reaction: Downward causation is the key issue in any debate about whether minds exhibit excitingly 'emergent' properties that somehow put them outside the realm of normal physics. I take that to be nonsense, and I side with science here. |
| 22976 | Memories are preserved separately, according to category [Augustine] |
| Full Idea: In memory everything is preserved separately, according to its category. | |
| From: Augustine (Confessions [c.398], X.08) | |
| A reaction: This strikes me as the first seeds of the idea that the mind functions by means of mental files. Our memories of cats are 'close to' or 'linked to' our memories of dogs. |
| 22985 | Everyone wants happiness [Augustine] |
| Full Idea: Surely happiness is what everyone wants, so much so that there can be none who do not want it? | |
| From: Augustine (Confessions [c.398], X.20) | |
| A reaction: His concept of happiness is, of course, religious. Occasionally you meet habitual grumblers about life who give the impression that they are only happy when they are discontented. So happiness is achieving desires, not feeling good? |
| 14884 | The shortest path to happiness is forgetfulness, the path of animals (but of little value) [Nietzsche] |
| Full Idea: If happiness were the goal, then animals would be the highest creatures. Their cynicism is grounded in forgetfulness: that is the shortest path to happiness, even if it is a happiness with little value. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [143]) | |
| A reaction: I would be reluctant to describe an apparently contented cow as 'happy'. Is a comatose person happy? Maybe happiness is fulfilling one's nature, like a monkey swinging through trees? |
| 14886 | Education is contrary to human nature [Nietzsche] |
| Full Idea: Education runs contrary to the nature of a human being. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 30 [06]) | |
| A reaction: Tell me about it! |
| 14883 | We should evaluate the past morally [Nietzsche] |
| Full Idea: For the past I desire above all a moral evaluation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [096]) | |
| A reaction: There is a bit of a contradiction with Idea 14819, of only a few years later. He was always interested in a historical approach to morality, but I'm not sure if his ethics gives a decent basis for moral assessments of remote historical eras. |
| 14882 | Protest against vivisection - living things should not become objects of scientific investigation [Nietzsche] |
| Full Idea: Protest against vivisection of living things, that is, those things that are not yet dead should be allowed to live and not immediately be treated as an object for scientific investigation. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 29 [027]) | |
| A reaction: Wow. How many other people had come up with this idea in 1873? |
| 14956 | Explanation by kinds and by clusters of properties just express the stability of reality [Ladyman/Ross] |
| Full Idea: Philosophers sometimes invoke natural kinds as if they explain the possibility of explanation. This is characteristically neo-scholastic. That anything can be explained, and that properties cluster together, express one fact: reality is relatively stable. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 5.6) | |
| A reaction: Odd idea. I would have thought that if there are indeed kinds and clusters, this would explain a great deal more than mere stability. Or, more accurately, they would invite a more substantial explanation than mere stability would seem to need. |
| 14957 | There is nothing more to a natural kind than a real pattern in nature [Ladyman/Ross] |
| Full Idea: Everything that a naturalist could legitimately want from the concept of a natural kind can be had simply by reference to real patterns. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 5.6) | |
| A reaction: I think I agree with this, and with the general idea that natural kinds are overrated. There are varying degrees of stability in nature, and where there is a lot of stability our inductive reasoning can get to work. And that's it. |
| 14865 | We do not know the nature of one single causality [Nietzsche] |
| Full Idea: We do not know the nature of one single causality. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [121]) |
| 14954 | Causation is found in the special sciences, but may have no role in fundamental physics [Ladyman/Ross] |
| Full Idea: The idea of causation, as it is used in science, finds its exemplars in the special sciences, and it is presently open empirical question whether that notion will have any ultimate role to play in fundamental physics. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 4.5) | |
| A reaction: Note that they seem to always have a notion of 'ultimate' physics hovering over their account. I wonder. There is nothing in this idea to make me think that I should eliminate the idea of causation from my metaphysics. |
| 14902 | Science may have uninstantiated laws, inferred from approaching some unrealised limit [Ladyman/Ross] |
| Full Idea: It is possible that uninstantiated laws can be established in science, and consequently bear explanatory weight, ..if we need reasons for thinking that the closer conditions get to some limit, the more they approximate to some ideal. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.3) | |
| A reaction: [The cite Hüttemann 2004] I am dubious about laws, but I take this to be a point in favour of inference to the best explanation, and against accounts of laws as supervenient of how things actually are. |
| 14871 | Laws of nature are merely complex networks of relations [Nietzsche] |
| Full Idea: All laws of nature are only relations between x, y and z. We define laws of nature as relations to an x, y, and z, each of which in turn, is known to us only in relation to other x's, y's and z's. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [235]) | |
| A reaction: This could be interpreted in Armstrong's terms, as only identifying the x's, y's and z's by their universals, and then seeing laws as how those universal relate. I suspect, though, that Nietzsche has a Humean regularity pattern in mind. |
| 14937 | That the universe must be 'made of' something is just obsolete physics [Ladyman/Ross] |
| Full Idea: It is a metaphysical residue of obsolete physics to suppose that the universe is 'made of' anything. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.2) | |
| A reaction: They quote Smolin as saying that it is 'processes' which are fundamental. And yet surely there must be something there to undergo a process? Surely we don't have eternal platonic processes? |
| 14900 | In physics, matter is an emergent phenomenon, not part of fundamental ontology [Ladyman/Ross] |
| Full Idea: Physics has taught us that matter in the sense of extended stuff is an emergent phenomenon that has no counterpart in fundamental ontology. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.3) | |
| A reaction: They contrast this point with futile debates among philosopher between atomists (partless particles) and gunkists (parts all the way down). |
| 14901 | Spacetime may well be emergent, rather than basic [Ladyman/Ross] |
| Full Idea: Contemporary physics takes very seriously the idea that spacetime itself is emergent from some more fundamental structure. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 1.2.3) |
| 14924 | If spacetime is substantial, what is the substance? [Ladyman/Ross] |
| Full Idea: It is fair to ask: if spacetime is a substance, what is the substance in question? | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.2) | |
| A reaction: Personally I love the question 'If it exists, what is it made of?', though physicists seem to think that this reveals a gormless misunderstanding. To my question Keith Hossack retorted 'What are the atoms made of?' |
| 22888 | To be aware of time it can only exist in the mind, as memory or anticipation [Augustine, by Bardon] |
| Full Idea: Augustine answers that for us to be aware of time it must exist only in the mind, …and the difference between past and future is just the difference between memory and anticipation. | |
| From: report of Augustine (Confessions [c.398]) by Adrian Bardon - Brief History of the Philosophy of Time 1 'Augustine's' | |
| A reaction: This is an extreme idealist view. Are we to say that the past consists only of what can be remembered, and the future only of what is anticipated? Absurd anti-realism, in my view. Where do his concepts come from, asks Le Poidevin. |
| 5984 | Maybe time is an extension of the mind [Augustine] |
| Full Idea: I begin to wonder whether time is an extension of the mind itself. | |
| From: Augustine (Confessions [c.398], XI.26) | |
| A reaction: The observation that the mind creates a 'specious present' (spreading experience out over a short fraction of second) reinforces this. Personally I like David Marshall's proposal that consciousness is entirely memory, which would deny this idea. |
| 5980 | How can ten days ahead be a short time, if it doesn't exist? [Augustine] |
| Full Idea: A short time ago or a short time ahead we might put at ten days, but how can anything which does not exist be either long or short? | |
| From: Augustine (Confessions [c.398], XI.15) | |
| A reaction: A nice question, which gets at the paradoxical nature of time very nicely. How can it be long, but non-existent? We could break the paradox by concluding '..and therefore time does exist', even though we can't see how. |
| 14938 | A fixed foliation theory of quantum gravity could make presentism possible [Ladyman/Ross] |
| Full Idea: It has been pointed out that presentism is an open question in so far as a fixed foliation theory of quantum gravity has not been ruled out. | |
| From: J Ladyman / D Ross (Every Thing Must Go [2007], 3.7.2 n75) | |
| A reaction: [They cite B.Monton for this point] I don't understand this idea, but I'll have it anyway. Google 'fixed foliation' for me, as I'm too busy. |
| 5979 | If the past is no longer, and the future is not yet, how can they exist? [Augustine] |
| Full Idea: Of the three divisions of time, how can two, the past and the future, be, when the past no longer is, and the future is not yet? | |
| From: Augustine (Confessions [c.398], XI.14) | |
| A reaction: This is the oldest bewilderment about time, which naturally leads us to the thought that time cannot actually 'exist'. The remark implies that at least 'now' is safe, but that also succumbs to paradox pretty quickly. |
| 5981 | The whole of the current year is not present, so how can it exist? [Augustine] |
| Full Idea: We cannot say that the whole of the current year is present, and if the whole of it is not present, the year is not present. | |
| From: Augustine (Confessions [c.398], XI.15) | |
| A reaction: Another nice way of presenting the paradox of time. We are in a particular year, so it has to be real. |
| 5978 | I know what time is, until someone asks me to explain it [Augustine] |
| Full Idea: I know well enough what time is, provided that nobody asks me; but if I am asked what it is and try to explain, I am baffled. | |
| From: Augustine (Confessions [c.398], XI.14) | |
| A reaction: A justly famous remark, even though it adds nothing to our knowledge of time. This sort of thought pushes us towards accepting many things as axiomatic, such as time, space, identity, persons, mind. |
| 5983 | I disagree with the idea that time is nothing but cosmic movement [Augustine] |
| Full Idea: I once heard a learned man say that time is nothing but the movement of the sun and the moon and the stars, but I do not agree. | |
| From: Augustine (Confessions [c.398], XI.22) | |
| A reaction: It is tempting to say that you either take time or movement as axiomatic, and describe one in terms of the other, but you are stuck unable to give the initial statement of the axiom without mentioning the second property you were saving for later. |
| 5977 | Heaven and earth must be created, because they are subject to change [Augustine] |
| Full Idea: The fact that heaven and earth are there proclaims that they were created, for they are subject to change and variation; ..the meaning of change and variation is that something is there which was not there before. | |
| From: Augustine (Confessions [c.398], XI.04) | |
| A reaction: It seems possible that the underlying matter is eternal (as in various conservation laws, such as that of energy), and that all change is in the form rather than the substance. |
| 22887 | If God existed before creation, why would a perfect being desire to change things? [Augustine, by Bardon] |
| Full Idea: If nothing existed by God before creation, then what could have happened to, or within, God that led God to decide to create the universe at that particular moment? Why would an eternal or perfect being want or need to change? | |
| From: report of Augustine (Confessions [c.398]) by Adrian Bardon - Brief History of the Philosophy of Time 1 'Augustine's' | |
| A reaction: I suppose you could reply that change is superior to stasis, but then why did God delay the creation? |
| 5976 | If God is outside time in eternity, can He hear prayers? [Augustine] |
| Full Idea: O Lord, since you are outside time in eternity, are you unaware of the things that I tell you? | |
| From: Augustine (Confessions [c.398], XI.01) | |
| A reaction: This strikes me as the single most difficult and most elusive question about the nature of a supreme divine being. If the being is trapped in time, as we are, it is greatly diminished, and if it is outside, it is hard to see how it could be a participant. |
| 14864 | The Greeks lack a normative theology: each person has their own poetic view of things [Nietzsche] |
| Full Idea: The Greeks lack a normative theology: everyone has the right to deal with it in a poetic manner and he can believe whatever he wants. | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1872-74 [1873], 19 [110]) | |
| A reaction: There is quite a lot of record of harshness towards atheists, and the trial of Socrates seems to have been partly over theology. However, no proper theological texts have come down, or records of the teachings of the priests. |
