125 ideas
23350 | A wise philosophers uses reason to cautiously judge each aspect of living [Epictetus] |
Full Idea: The sinews of a philosopher are desire that never fails in its achievement; aversion that never meets with what it would avoid; appropriate impulse; carefully considered purpose; and assent that is never precipitate. | |
From: Epictetus (The Discourses [c.56], 2.08.29) | |
A reaction: This is a very individual view of wisdom and the philosopher, whereas wisdom is often thought to have a social role. Is it not important for a philosopher to at least offer advice? |
23355 | The task of philosophy is to establish standards, as occurs with weights and measures [Epictetus] |
Full Idea: Things are judged and weighed, when we have the standards ready. This is the task of philosophy: to examine and establish the standards. | |
From: Epictetus (The Discourses [c.56], 2.11.24) | |
A reaction: It is interesting that this gives philosophers a very specific social role, and also that it seems to identify epistemology as First Philosophy. Other disciplines, of course, establish their own standards without reference to philosophy. |
21394 | Philosophy is knowing each logos, how they fit together, and what follows from them [Epictetus] |
Full Idea: [Philosophical speculation] consists in knowing the elements of 'logos', what each of them is like, how they fit together, and what follows from them. | |
From: Epictetus (The Discourses [c.56], 4.08.14), quoted by A.A. Long - Hellenistic Philosophy 4.1 | |
A reaction: [Said to echo Zeno] If you substitute understanding for 'logos' (plausibly), I think this is exactly the view of philosophy I would subscribe to. We want to understand each aspect of life, and we want those understandings to cohere with one another. |
20876 | Philosophy investigates the causes of disagreements, and seeks a standard for settling them [Epictetus] |
Full Idea: The start of philosophy is perception of the mutual conflict among people, and a search for its cause, plus the rejection and distrust of mere opinion, an investigation to see if opinion is right, and the discovery of some canon, like scales for weighing. | |
From: Epictetus (The Discourses [c.56], 2.11.13) | |
A reaction: So the number one aim of philosophy is epistemological, to find the criterion for true opinion. But it starts in real life, and would cease to trade if people would just agree. I think we should set the bar higher than that. |
15010 | Your metaphysics is 'cheating' if your ontology won't support the beliefs you accept [Sider] |
Full Idea: Ontological 'cheaters' are those ne'er-do-well metaphysicians (such as presentists, phenomenalists, or solipsists) who refuse to countenance a sufficiently robust conception of the fundamental to underwrite the truths they accept. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.4) | |
A reaction: Presentists are placed in rather insalubrious company here, The notion of 'cheaters' is nice, and I associate it with Australian philosophy, and the reason that was admired by David Lewis. |
14977 | Metaphysics is not about what exists or is true or essential; it is about the structure of reality [Sider] |
Full Idea: Metaphysics, at bottom, is about the fundamental structure of reality. Not about what's necessarily true. Not about what properties are essential. Not about conceptual analysis. Not about what there is. Structure. | |
From: Theodore Sider (Writing the Book of the World [2011], 01) | |
A reaction: The opening words of his book. I take them to be absolutely correct, and to articulate the new orthodoxy about metaphysics which has emerged since about 1995. He expands this as being about patterns, categories and joints. |
14994 | Extreme doubts about metaphysics also threaten to undermine the science of unobservables [Sider] |
Full Idea: The most extreme critics of metaphysics base their critique on sweeping views about language (logical positivism), or knowledge (empiricism), ...but this notoriously threatens the science of unobservables as much as it threatens metaphysics. | |
From: Theodore Sider (Writing the Book of the World [2011], 05.1) | |
A reaction: These criticisms also threaten speculative physics (even about what is possibly observable). |
15003 | It seems unlikely that the way we speak will give insights into the universe [Sider] |
Full Idea: It has always seemed odd that insight into the fundamental workings of the universe should be gained by reflection on how we think and speak. | |
From: Theodore Sider (Writing the Book of the World [2011], 07.8) | |
A reaction: A nice expression of what should by now be obvious to all philosophers - that analysis of language is not going to reveal very much. It is merely clearing the undergrowth so that we can go somewhere. |
14986 | Conceptual analysts trust particular intuitions much more than general ones [Sider] |
Full Idea: Conceptual analysts generally regard intuitive judgements about particular cases as being far more diagnostic than intuitive judgements about general principles. | |
From: Theodore Sider (Writing the Book of the World [2011], 02.4 n7) | |
A reaction: Since I take the aim to be the building up an accurate picture about general truths, it would be daft to just leap to our intuitions about those general truths. Equally you can't cut intuition out of the picture (pace Ladyman). |
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) |
23344 | Reason itself must be compounded from some of our impressions [Epictetus] |
Full Idea: What is reason itself? Something compounded from impressions of a certain kind. | |
From: Epictetus (The Discourses [c.56], 1.20.05) | |
A reaction: This seems to be the only escape from the dead end attempts to rationally justify reason. Making reason a primitive absolute is crazy metaphysics. |
23343 | Because reason performs all analysis, we should analyse reason - but how? [Epictetus] |
Full Idea: Since it is reason that analyses and completes all other things, reason itself should not be left unanalysed. But by what shall it be analysed? ..That is why philosophers put logic first, just as when measuring grain we first examine the measure. | |
From: Epictetus (The Discourses [c.56], 1.17.01) | |
A reaction: The problem of the definitive metre rule in Paris. I say we have to test reason against the physical world, and the measure of reason is truth. Something has to be primitive, but reason is too vague for that role. Idea 23344 agrees with me! |
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. |
15015 | It seems possible for a correct definition to be factually incorrect, as in defining 'contact' [Sider] |
Full Idea: Arguably, 'there is absolutely no space between two objects in contact' is false, but definitional of 'contact'. ...We need a word for true definitional sentences. I propose: 'analytic'. | |
From: Theodore Sider (Writing the Book of the World [2011], 09.8) |
14981 | Philosophical concepts are rarely defined, and are not understood by means of definitions [Sider] |
Full Idea: Philosophical concepts of interest are rarely reductively defined; still more rarely does our understanding of such concepts rest on definitions. ...(We generally understand concepts to the extent that we know what role they play in thinking). | |
From: Theodore Sider (Writing the Book of the World [2011], 02.1) | |
A reaction: I'm not sure that I agree with this. I suspect that Sider has the notion of definition in mind that is influenced by lexicography. Aristotle's concept of definition I take to be lengthy and expansive, and that is very relevant to philosophy. |
14992 | We don't care about plain truth, but truth in joint-carving terms [Sider] |
Full Idea: What we care about is truth in joint-carving terms, not just truth. | |
From: Theodore Sider (Writing the Book of the World [2011], 04.5) | |
A reaction: The thought is that it matters what conceptual scheme is used to express the truth (the 'ideology'). Truths can be true but uninformative or unexplanatory. |
15012 | Orthodox truthmaker theories make entities fundamental, but that is poor for explanation [Sider] |
Full Idea: According to the entrenched truthmaker theorist, the fundamental facts consist just of facts citing the existence of entities. It's hard to see how all the complexity we experience could possibly be explained from that sparse basis. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.5) | |
A reaction: This may be the 'entrenched' truthmaker view, but it is not clear why there could not be more complicated fundamental truthmakers, with structure as well as entities. And powers. |
15023 | The Barcan schema implies if X might have fathered something, there is something X might have fathered [Sider] |
Full Idea: If we accept the Barcan and converse Barcan schemas, this leads to surprising ontological consequences. Wittgenstein might have fathered something, so, by the Barcan schema, there is something that Wittgenstein might have fathered. | |
From: Theodore Sider (Writing the Book of the World [2011], 11.9) | |
A reaction: [He cites Tim Williamson for this line of thought] I was liking the Barcan picture, by now I am backing away fast. They cannot be serious! |
15004 | 'Gunk' is an object in which proper parts all endlessly have further proper parts [Sider] |
Full Idea: An object is 'gunky' if each of its parts has further proper parts; thus gunk involves infinite descent in the part-whole relation. | |
From: Theodore Sider (Writing the Book of the World [2011], 07.11.2) |
14984 | Which should be primitive in mereology - part, or overlap? [Sider] |
Full Idea: Should our fundamental theory of part and whole take 'part' or 'overlap' as primitive? | |
From: Theodore Sider (Writing the Book of the World [2011], 02.3) |
14980 | There is a real issue over what is the 'correct' logic [Sider] |
Full Idea: Certain debates over the 'correct' logic are genuine, and not linguistic or conceptual. | |
From: Theodore Sider (Writing the Book of the World [2011], 01.3) | |
A reaction: It is rather hard to give arguments in favour of this view, but I am pleased to have the authority of Sider with me. |
15000 | 'It is raining' and 'it is not raining' can't be legislated, so we can't legislate 'p or ¬p' [Sider] |
Full Idea: I cannot legislate-true 'It is raining' and I cannot legislate true 'It is not raining', so if I cannot legislate either true then I cannot legislate-true the disjunction 'it is raining or it is not raining'. | |
From: Theodore Sider (Writing the Book of the World [2011], 06.5) | |
A reaction: This strikes me as a very simple and very persuasive argument against the idea that logic is a mere convention. I take disjunction to be an abstract summary of how the world works. Sider seems sympathetic. |
15020 | Classical logic is good for mathematics and science, but less good for natural language [Sider] |
Full Idea: Despite its brilliant success in mathematics and fundamental science, classical logic applies uneasily to natural language. | |
From: Theodore Sider (Writing the Book of the World [2011], 10.6) | |
A reaction: He gives examples of the conditional, and debates over the meaning of 'and', 'or' and 'not', and also names and quantifiers. Many modern philosophical problems result from this conflict. |
15029 | Modal accounts of logical consequence are simple necessity, or essential use of logical words [Sider] |
Full Idea: The simplest modal account is that logical consequence is just necessary consequence; another modal account says that logical consequences are modal consequences that involve only logical words essentially. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.3) | |
A reaction: [He cites Quine's 'Carnap and Logical Truth' for the second idea] Sider is asserting that Humeans like him dislike modality, and hence need a nonmodal account of logical consequence. |
15019 | Define logical constants by role in proofs, or as fixed in meaning, or as topic-neutral [Sider] |
Full Idea: Some say that logical constants are those expressions that are defined by their proof-theoretic roles, others that they are the expressions whose semantic values are permutation-invariant, and still others that they are the topic-neutral expressions. | |
From: Theodore Sider (Writing the Book of the World [2011], 10.3) | |
A reaction: [He cites MacFarlane 2005 as giving a survey of this] |
15001 | 'Tonk' is supposed to follow the elimination and introduction rules, but it can't be so interpreted [Sider] |
Full Idea: 'Tonk' is stipulated by Prior to stand for a meaning that obeys the elimination and introduction rules; but there simply is no such meaning; 'tonk' cannot be interpreted so as to obey the rules. | |
From: Theodore Sider (Writing the Book of the World [2011], 06.5) | |
A reaction: 'Tonk' thus seems to present a problem for so-called 'natural' deduction, if the natural deduction consists of nothing more than obey elimination and introduction rules. |
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) | |
A reaction: This seems to be rhetorical, rather a precise theory, given that the One is said to be eternal and unchanging. The One is not just what we call 'reality'. |
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. |
15017 | Supervenience is a modal connection [Sider] |
Full Idea: Supervenience is just a kind of modal connection. | |
From: Theodore Sider (Writing the Book of the World [2011], 09.10) | |
A reaction: It says what would happen, as well as what does. This is big for Sider because he rejects modality as a feature of actuality. I think the world is crammed full of modal facts, so supervenience should be a handy tool for me. |
15008 | Is fundamentality in whole propositions (and holistic), or in concepts (and atomic)? [Sider] |
Full Idea: The locus of fundamentality for a Finean is the whole proposition, whereas for me it is the proposition-part. Fundamentality is holistic for the Finean, atomistic for me. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.3) | |
A reaction: This is because Kit Fine has pushed fundamentality into a relation (grounding), rather than into the particular entities involved (if I understand Sider's reading of him aright). My first intuition is to side with Sider. I'm on Sider's side... |
15013 | Tables and chairs have fundamental existence, but not fundamental natures [Sider] |
Full Idea: The existence of tables and chairs is just as fundamental as the existence of electrons (in contrast, perhaps, with smirks and shadows, which do not exist fundamentally). However, tables and chairs have nonfundamental natures. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.7) | |
A reaction: This seems to be a good clarification, and to me the 'nature' of something points towards its essence. However, I suppose he refers here to the place of something in a dependence hierarchy. But then, why does it have that place? What power? |
15014 | Unlike things, stuff obeys unrestricted composition and mereological essentialism [Sider] |
Full Idea: Stuff obeys unrestricted composition and mereological essentialism, whereas things do not. | |
From: Theodore Sider (Writing the Book of the World [2011], 09.6.2) | |
A reaction: [He cites Markosian 2004] |
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) | |
A reaction: These seems to thoroughly pre-empt Plato's Theory of Forms a century before he created it. Which shows (as Simone Weil says) that Plato was just part of a long tradition. |
15009 | We must distinguish 'concrete' from 'abstract' and necessary states of affairs. [Sider] |
Full Idea: The truthmaker theorist's 'concrete' states of affairs must be distinguished from necessarily existing 'abstract' states of affairs. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.4) | |
A reaction: [He cites Plantinga's 'Nature of Necessity' for the second one; I presume the first one is Armstrong] |
14983 | Accept the ontology of your best theory - and also that it carves nature at the joints [Sider] |
Full Idea: We can add to the Quinean advice to believe the ontology of your best theory that you should also regard the ideology of your best theory as carving at the joints. | |
From: Theodore Sider (Writing the Book of the World [2011], 02.3) | |
A reaction: I've never liked the original Quinean formulation, but this is much better. I just take my ontological commitments to reside in me, not in whatever theory I am currently employing. I may be dubious about my own theory. |
14978 | A property is intrinsic if an object alone in the world can instantiate it [Sider] |
Full Idea: Chisholm and Kim proposed a modal notion of an 'intrinsic' property - that a property is intrinsic if and only if it is possibly instantiated by an object that is alone in the world. | |
From: Theodore Sider (Writing the Book of the World [2011], 01.2) | |
A reaction: [He cites Chisholm 1976:127 and Kim 1982:59-60] Sider then gives a counterexample from David Lewis (Idea 14979). |
14995 | Predicates can be 'sparse' if there is a universal, or if there is a natural property or relation [Sider] |
Full Idea: For Armstrong a predicate is sparse when there exists a corresponding universal; for Lewis, a predicate is sparse when there exists a corresponding natural property or relation. | |
From: Theodore Sider (Writing the Book of the World [2011], 06) | |
A reaction: I like 'sparse' properties, but have no sympathy with Armstrong, and am cautious about Lewis. I like Shoemaker's account, which makes properties even sparser. 'Abundant' so-called properties are my pet hate. They are 'predicates'! |
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) |
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) |
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) |
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) |
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) |
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) |
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) |
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. |
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) |
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) |
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) |
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) |
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) |
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. |
15026 | Essence (even if nonmodal) is not fundamental in metaphysics [Sider] |
Full Idea: We should not regard nonmodal essence as being metaphysically basic: fundamental theories need essence no more than they need modality. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.1) | |
A reaction: He is discussing Kit Fine, and notes that Fine offers a nonmodal view of essence, but still doesn't make it fundamental. I am a fan of essences, but making them fundamental in metaphysics seems unlikely. |
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. |
15031 | Modal terms in English are entirely contextual, with no modality outside the language [Sider] |
Full Idea: English modals are context-dependent through and through; there is no stable 'outer modality'. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.7) | |
A reaction: Sider has been doing so well up to here. To me this is swallowing the bait of linguistic approaches to philosophy which he has fought so hard to avoid. |
15030 | Humeans say that we decide what is necessary [Sider] |
Full Idea: The spirit of Humeanism is that necessity is not a realm to be discovered. We draw the lines around what is necessary. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.3) | |
A reaction: I disagree, but it is hard to argue the point. My intuitions are that the obvious necessities of logic and mathematics reflect the way nature has to be. The deepest necessities are patterns (about which God has no choice). |
15027 | If truths are necessary 'by convention', that seems to make them contingent [Sider] |
Full Idea: If □φ says that φ is true by convention, then □φ would apparently turn out to be contingent, since statements about what conventions we adopt are not themselves true by convention. The main axioms of S4 and S5 would be false. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.1) |
15028 | Conventionalism doesn't seem to apply to examples of the necessary a posteriori [Sider] |
Full Idea: Conventionalism is apparently inapplicable to Kripke's and Putnam's examples of the necessary a posteriori (and, relatedly, to de re modality). | |
From: Theodore Sider (Writing the Book of the World [2011], 12.1) | |
A reaction: [Sidelle 1989 discusses this] |
15033 | Humeans says mathematics and logic are necessary because that is how our concept of necessity works [Sider] |
Full Idea: Why are logical (or mathematical, or analytic...) truths necessary? The Humean's answer is that this is just how our concept of necessity works. | |
From: Theodore Sider (Writing the Book of the World [2011], 12.11) | |
A reaction: This is why I (unlike Sider) am not a Humean. If we agreed that 'necessary' meant 'whatever is decreed by the Pope', that would so obviously not be necessary that we would have to start searching nature for true necessities. |
15025 | The world does not contain necessity and possibility - merely how things are [Sider] |
Full Idea: At bottom, the world is an amodal place. Necessity and possibility do not carve at the joints; ultimate reality is not 'full of threats and promises' (Goodman). The book of the world says how things are, not how they must or might be. | |
From: Theodore Sider (Writing the Book of the World [2011], 12) | |
A reaction: Nice to see this expressed so clearly. I find it much easier to disagree with as a result. At first blush I would say that if you haven't noticed that the world is full of threats and promises, you should wake up and smell the coffee. Actuality is active. |
23359 | We can't believe apparent falsehoods, or deny apparent truths [Epictetus] |
Full Idea: It is impossible to assent to an apparent falsehood, or to deny an apparent truth. | |
From: Epictetus (The Discourses [c.56], 3.07.15) | |
A reaction: The way some philosophers write you would think that most beliefs just result from private whims or social fashion. That happens, of course, but most beliefs result from direct contact with reality. |
23356 | Self-evidence is most obvious when people who deny a proposition still have to use it [Epictetus] |
Full Idea: It is about the strongest proof one could offer of a proposition being evident, that even he who contradicts it finds himself having to make use of it. | |
From: Epictetus (The Discourses [c.56], 2.20.01) | |
A reaction: Philosophers sometimes make fools of themselves by trying, by the use of elaborate sophistry, to demolish propositions which are self-evidently true. Don't be one of these philosophers! |
14988 | A theory which doesn't fit nature is unexplanatory, even if it is true [Sider] |
Full Idea: 'Theories' based on bizarre, non-joint-carving classifications are unexplanatory even when true. | |
From: Theodore Sider (Writing the Book of the World [2011], 03.1) | |
A reaction: This nicely pinpoints why I take explanation to be central to whole metaphysical enterprise. |
14982 | If I used Ramsey sentences to eliminate fundamentality from my theory, that would be a real loss [Sider] |
Full Idea: If the entire theory of this book were replaced by its Ramsey sentence, omitting all mention of fundamentality, something would seem to be lost. | |
From: Theodore Sider (Writing the Book of the World [2011], 02.2 n2) | |
A reaction: It is a moot point whether Ramsey sentences actually eliminate anything from the ontology, but trying to wriggle out of ontological commitment looks a rather sad route to follow. |
14989 | Problem predicates in induction don't reflect the structure of nature [Sider] |
Full Idea: 'Is nonblack', 'is a nonraven', and 'grue' fail to carve at the joints. | |
From: Theodore Sider (Writing the Book of the World [2011], 03.3) | |
A reaction: A lot more than this needs to said, but this remark encapsulates why I find most of these paradoxes of induction uninteresting. They are all the creations of logicians, rather than of scientists. |
14997 | Two applications of 'grue' do not guarantee a similarity between two things [Sider] |
Full Idea: The applicability of 'grue' to each of a pair of particulars does not guarantee the similarity of those particulars. | |
From: Theodore Sider (Writing the Book of the World [2011], 06.2) | |
A reaction: Grue is not a colour but a behaviour. If two things are 'mercurial' or 'erratic', will that ensure a similarity at any given moment? |
14990 | Bayes produces weird results if the prior probabilities are bizarre [Sider] |
Full Idea: In the Bayesian approach, bizarre prior probability distributions will result in bizarre responses to evidence. | |
From: Theodore Sider (Writing the Book of the World [2011], 03.3) | |
A reaction: This is exactly what you find when people with weird beliefs encounter ridiculous evidence for things. It doesn't invalidate the formula, but just says rubbish in rubbish out. |
15005 | Explanations must cite generalisations [Sider] |
Full Idea: Explanations must cite generalisations. | |
From: Theodore Sider (Writing the Book of the World [2011], 07.13) | |
A reaction: I'm uneasy about this. Presumably some events have a unique explanation - a unique mechanism, perhaps. Language is inescapably general in its nature - which I take to be Aristotle's reason for agreeing the Sider. [Sider adds mechanisms on p.159] |
15011 | If the ultimate explanation is a list of entities, no laws, patterns or mechanisms can be cited [Sider] |
Full Idea: Ultimate explanations always terminate in the citation of entities; but since a mere list of entities is so unstructured, these 'explanations' cannot be systematized with detailed general laws, patterns, or mechanisms. | |
From: Theodore Sider (Writing the Book of the World [2011], 08.5) | |
A reaction: We just need to distinguish between ultimate ontology and ultimate explanations. I think explanations peter out at the point where we descend below the mechanisms. Patterns or laws don't explain on their own. Causal mechanisms are the thing. |
15018 | Intentionality is too superficial to appear in the catalogue of ultimate physics [Sider] |
Full Idea: One day the physicists will complete the catalogue of ultimate and irreducible properties of things. When they do, the like of spin, charm and charge will perhaps appear on the list. But aboutness sure won't; intentionality simply doesn't go that deep. | |
From: Theodore Sider (Writing the Book of the World [2011], 4 Intro) | |
A reaction: Fodor's project is to give a reductive, and perhaps eliminative, account of intentionality of mind, while leaving open what one might do with the phenomenological aspects. Personally I don't think they will appear on the list either. |
23329 | We make progress when we improve and naturalise our choices, asserting their freedom [Epictetus] |
Full Idea: Progress is when any of you turns to his own faculty of choice, working at it and perfecting it, so as to bring it fully into harmony with nature; elevated, free, unrestrained, unhindered, faithful, self-respecting. | |
From: Epictetus (The Discourses [c.56], 1.04.18) | |
A reaction: [See also Disc.3.5.7] Rationality is the stoic concept of being in 'harmony with nature'. It appears (from reading Frede) that this may be the FIRST EVER reference to free will. Note the very rhetorical way in which it is presented. |
23330 | Freedom is making all things happen by choice, without constraint [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: The idea of 'free' will seems to have resulted from a wide extension of the idea of constraint, with global determinism lurking in the background. |
23342 | Freedom is acting by choice, with no constraint possible [Epictetus] |
Full Idea: He is free for whom all things happen in accordance with his choice, and whom no one can constrain. | |
From: Epictetus (The Discourses [c.56], 1.12.09) | |
A reaction: Presumable this means that constraint is absolutely impossible, even by Zeus, and not just contingent possibility, when no one sees me raid the fridge. |
23332 | Zeus gave me a nature which is free (like himself) from all compulsion [Epictetus] |
Full Idea: Zeus placed my good nature in my own power, and gave it to me as he has it himself, free from all hindrance, compulsion and restraint. | |
From: Epictetus (The Discourses [c.56], 3.03.10) | |
A reaction: Although Frede traces the origin of free will to the centrality of choice in moral life (and hence to the elevation of its importance), this remark shows that there is a religious aspect to it. Zeus is supreme, and obviously has free will. |
23331 | Not even Zeus can control what I choose [Epictetus] |
Full Idea: You can fetter my leg, but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This is the beginnings of the idea of free will. It is based on the accurate observation that the intrinsic privacy of a mind means that no external force can be assured of controlling its actions. Epictetus failed to think of internal forces. |
23338 | You can fetter my leg, but not even Zeus can control my power of choice [Epictetus] |
Full Idea: What are you saying, man? Fetter me? You will fetter my leg; but not even Zeus himself can get the better of my choice. | |
From: Epictetus (The Discourses [c.56], 1.01.23) | |
A reaction: This seems to be the beginning of the idea of 'absolute' freedom, which is conjured up to preserve perfect inegrity and complete responsibility. Obviously you can be prevented from doing what you choose, so this is not compatibilism. |
20875 | If we could foresee the future, we should collaborate with disease and death [Epictetus] |
Full Idea: The philosophers are right to say that if the honorable and good person knew what was going to happen, he would even collaborate with disease, death and lameness. | |
From: Epictetus (The Discourses [c.56], 2.10.05) | |
A reaction: The 'philosophers' must be the earlier stoics, founders of his school. |
23347 | If I know I am fated to be ill, I should want to be ill [Epictetus] |
Full Idea: If I really knew that it was ordained for me to be ill at this moment, I would aspire to be so. | |
From: Epictetus (The Discourses [c.56], 2.06.10) | |
A reaction: The rub, of course, is that it is presumably impossible to know what is fated. Book 2.7 is on divination. I don't see any good in a mortally ill person desiring, for that reason alone, to die. Rage against the dying of the light, I say. |
14999 | Prior to conventions, not all green things were green? [Sider] |
Full Idea: It is absurd to say that 'before we introduced our conventions, not all green things were green'. | |
From: Theodore Sider (Writing the Book of the World [2011], 06.5) | |
A reaction: Well… Different cultures label the colours of the rainbow differently, and many of them omit orange. I suspect the blue/green borderline has shifted. |
14998 | Conventions are contingent and analytic truths are necessary, so that isn't their explanation [Sider] |
Full Idea: To suggest that analytic truths make statements about linguistic conventions is a nonstarter; statements about linguistic conventions are contingent, whereas the statements made by typical analytic sentences are necessary. | |
From: Theodore Sider (Writing the Book of the World [2011], 06.5) | |
A reaction: That 'anything yellow is extended' is not just a convention should be fairly obvious, and it is obviously necessary. But we can say that bachelors are necessarily unmarried men - given the current convention. |
15016 | Analyticity has lost its traditional role, which relied on truth by convention [Sider] |
Full Idea: Nothing can fully play the role traditionally associated with analyticity, for much of that traditional role presupposed the doctrine of truth by convention. | |
From: Theodore Sider (Writing the Book of the World [2011], 09.8) | |
A reaction: Sider rejects Quine's attack on analyticity, but accepts his critique of truth by convention. |
23325 | Epictetus developed a notion of will as the source of our responsibility [Epictetus, by Frede,M] |
Full Idea: The notion of will in Epictetus is clearly developed to pinpoint the source of our responsibility for our actions and to identify precisely what it is that makes them our own doings. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: So the key move is that responsibility needs a 'source', rather than being a generalisation about how our actions arise. The next step is demand an 'ultimate' source, and this leads to the idea that this new will is 'free'. This will can be good or bad. |
20873 | Tragedies are versified sufferings of people impressed by externals [Epictetus] |
Full Idea: Tragedies are nothing but the sufferings of people who are impressed by externals, performed in the right sort of meter. | |
From: Epictetus (The Discourses [c.56], 1.04.26) | |
A reaction: The externals are things like honour, position and wealth. Wonderfully dismissive! |
23364 | Homer wrote to show that the most blessed men can be ruined by poor judgement [Epictetus] |
Full Idea: Did not Homer write to show us that the noblest, the strongest, the richest, the handsomest of men may nevertheless be the most unfortunate and wretched, if they do not hold the judgements that they ought to hold? | |
From: Epictetus (The Discourses [c.56], 4.10.36) | |
A reaction: This seems to be right. He clearly wrote about the greatest and most memorable events of recent times, but not just to record triumphs, because almost every hero (in the Iliad, at least) ends in disaster. |
23340 | We consist of animal bodies and god-like reason [Epictetus] |
Full Idea: We have these two elements mingled within us, a body in common with the animals, and reason and intelligence in common with the gods. | |
From: Epictetus (The Discourses [c.56], 1.03.03) | |
A reaction: This is what I call Human Exceptionalism, but note that it doesn't invoke a Christian soul or spiritual aspect. This separation of reason goes back at least to Plato. High time we stopped thinking this way. Animals behave very sensibly. |
23358 | Every species produces exceptional beings, and we must just accept their nature [Epictetus] |
Full Idea: In every species nature produces some exceptional being, in oxen, in dogs, in bees, in horses. We do not say to them 'Who are you?' It will tell you 'I am like the purple in the robe. Do not expect me to be like the rest, or find fault with my nature'. | |
From: Epictetus (The Discourses [c.56], 3.01.23) | |
A reaction: This idea began with Aristotle's 'great soul', and presumably culminates in Nietzsche, who fills in more detail. In the modern world such people are mostly nothing but trouble. |
23339 | I will die as becomes a person returning what he does not own [Epictetus] |
Full Idea: When the time comes, then I will die - as becomes a person who gives back what is not his own. | |
From: Epictetus (The Discourses [c.56], 1.01.32) | |
A reaction: There is a tension between his demand that he have full control of his choices, and this humility that says his actual life is not his own. The things which can't be controlled, though, are 'indifferents' so life and death are indifferent. |
23345 | Don't be frightened of pain or death; only be frightened of fearing them [Epictetus] |
Full Idea: It is not pain or death that is to be feared, but the fear of pain or death. | |
From: Epictetus (The Discourses [c.56], 2.01.13) | |
A reaction: These two cases are quite different, I would say. I'm much more frightened of pain than I am of the fear of pain, and the opposite view seems absurd. About death, though, I think this is right. Mostly I'm with Spinoza: think about life, not death. |
23357 | Knowledge of what is good leads to love; only the wise, who distinguish good from evil, can love [Epictetus] |
Full Idea: Whoever has knowledge of good things would know how to love them; and how could he who cannot distinguish good things from evil still have to power to love? It follows that the wise man alone has the power to love. | |
From: Epictetus (The Discourses [c.56], 2.22.03) | |
A reaction: A rather heartwarming remark, but hard to assess for its truth. Evil people are unable to love? Not even love a cat, or their favourite car? We would never call someone wise if they lacked love. |
23363 | The evil for everything is what is contrary to its nature [Epictetus] |
Full Idea: Where is the paradox if we say that what is evil for everything is what is contrary to its nature? | |
From: Epictetus (The Discourses [c.56], 4.01.125) | |
A reaction: A very Greek view. For humans, it must rely on the belief that human nature is essentially good. If I am sometimes grumpy and annoying, why is that not part of my nature? |
23328 | The essences of good and evil are in dispositions to choose [Epictetus] |
Full Idea: The essence of the good is a certain disposition of our choice, and essence of evil likewise. | |
From: Epictetus (The Discourses [c.56], 1.29.01) | |
A reaction: This is the origin of Kant's famous view, that the only true good is a good will. This is the alternative to good character or good states of affairs as the good. It points towards the modern more legalistic view of morality, as concerning actions. |
23362 | All human ills result from failure to apply preconceptions to particular cases [Epictetus] |
Full Idea: The cause of all human ills is that people are incapable of applying their general preconceptions to particular cases. | |
From: Epictetus (The Discourses [c.56], 4.01.42) | |
A reaction: I'm not sure whether 'preconceptions' is meant pejoratively (as unthinking, and opposed to true principles). This sounds like modern particularism (e.g. Jonathan Dancy) to the letter. |
23353 | We have a natural sense of honour [Epictetus] |
Full Idea: What faculty do you mean? - Have we not a natural sense of honour? - We have. | |
From: Epictetus (The Discourses [c.56], 2.10.22) | |
A reaction: This seems unlikely, given the lower status that honour now has with us, compared to two hundred years ago. But there may be a natural sense of status, and of humiliation and shame. |
23354 | If someone harms themselves in harming me, then I harm myself by returning the harm [Epictetus] |
Full Idea: Since he has harmed himself by wronging me, shall not I harm myself by harming him? | |
From: Epictetus (The Discourses [c.56], 2.10.26) | |
A reaction: I am very keen on this idea. See Hamlet's remarks to Polonius about 'honour and dignity'. The best strategy for achieving moral excellence is to focus on our own characters, rather than how to act, and to respond to others. |
23324 | In the Discourses choice [prohairesis] defines our character and behaviour [Epictetus, by Frede,M] |
Full Idea: In Epictetus's 'Discourses' the notion of choice [prohairesis] plays perhaps the central role. It is our prohairesis which defines us a person, as the sort of person we are; it is our prohairesis which determines how we behave. | |
From: report of Epictetus (The Discourses [c.56]) by Michael Frede - A Free Will 3 | |
A reaction: Frede is charting the gradual move in Greek philosophy from action by desire, reason and habit to action by the will (which then turns out to be 'free'). Character started as dispositions and ended as choices. |
23361 | Health is only a good when it is used well [Epictetus] |
Full Idea: Is health a good and sickness an evil? No. Health is good when used well, and bad when used ill. | |
From: Epictetus (The Discourses [c.56], 3.20.04) | |
A reaction: Although I like the idea that health is a natural value, which bridges the gap from facts to values (as a successful function), there is no denying that the health of very evil people is not something the rest of us hope for. |
23346 | A person is as naturally a part of a city as a foot is part of the body [Epictetus] |
Full Idea: Just as the foot in detachment is no longer a foot, so you in detachment are not longer a man. For what is a man? A part of a city, first. | |
From: Epictetus (The Discourses [c.56], 2.05.26) | |
A reaction: It is, of course, not true that a detached foot ceases to be a foot (and an isolated human is still a human). This an extreme version of the Aristotelian idea that we are essentially social. It is, though, the sort of view favoured by totalitarianism. |
23351 | We are citizens of the universe, and principal parts of it [Epictetus] |
Full Idea: You are a citizen of the universe, and a part of it; and no subservient, but a principal part of it. | |
From: Epictetus (The Discourses [c.56], 2.10.03) | |
A reaction: He got this view from Diogenes of Sinope, one of his heroes. What community you are a part of seems to be a choice as much as a fact. Am I British or a European? |
20874 | A citizen is committed to ignore private advantage, and seek communal good [Epictetus] |
Full Idea: The commitment of the citizen is to have no private advantage, not to deliberate about anything as though one were a separate part. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: This is the modern problem of whether democratic voters are choosing for themselves or for the community. I think we should make an active effort at every election to persuade voters to aim for the communal good. Cf Rawls. |
23352 | A citizen should only consider what is good for the whole society [Epictetus] |
Full Idea: The calling of a citizen is to consider nothing in terms of personal advantage, never to deliberate on anything as though detached from the whole, but be like our hand or foot. | |
From: Epictetus (The Discourses [c.56], 2.10.04) | |
A reaction: Fat chance of that in an aggressively capitalist society. I've always voted for what I thought was the common good, and was shocked to gradually realise that many people only vote for what promotes their own interests. Heigh ho. |
22604 | Punishing a criminal for moral ignorance is the same as punishing someone for being blind [Epictetus] |
Full Idea: You should ask 'Ought not this man to be put to death, who is deceived in things of the greatest importance, and is blinded in distinguishing good from evil?' …You then see how inhuman it is, and the same as 'Ought not this blind man to be put to death?' | |
From: Epictetus (The Discourses [c.56], 1.18.6-7) | |
A reaction: This is the doctrine of Socrates, that evil is ignorance (and weakness of will [akrasia] is impossible). Epictetus wants us to reason with the man, but what should be do if reasoning fails and he persists in his crimes? |
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) |
23349 | Asses are born to carry human burdens, not as ends in themselves [Epictetus] |
Full Idea: An ass is surely not born as an end in itself? No, but because we had need of a back that is able to carry burdens. | |
From: Epictetus (The Discourses [c.56], 2.08.07) | |
A reaction: This is the absurd human exceptionalism which plagues our thinking. It would be somewhat true of animals which are specifically bred for human work, such as large cart horses. |
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 |
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) |
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. |
14987 | Many of the key theories of modern physics do not appear to be 'laws' [Sider] |
Full Idea: That spacetime is 4D Lorentzian manifold, that the universe began with a singularity, and in a state of low entropy, are all central to physics, but it is a stretch to call them 'laws'. ...It has been argued that there are no laws of biology. | |
From: Theodore Sider (Writing the Book of the World [2011], 03.1) |
14985 | The notion of law doesn't seem to enhance physical theories [Sider] |
Full Idea: Adding the notion of law to physical theory doesn't seem to enhance its explanatory power. | |
From: Theodore Sider (Writing the Book of the World [2011], 02.4) | |
A reaction: I agree with his scepticism about laws, although Sider offers it as part of his scepticism about modal facts being included in explanations of actuality. Personally I like dispositions, but not laws. See the ideas of Stephen Mumford. |
14991 | Space has real betweenness and congruence structure (though it is not the Euclidean concepts) [Sider] |
Full Idea: In metaphysics, space is intrinsically structured; the genuine betweenness and congruence relations are privileged in a way that Euclidean-betweenness and Euclidean-congruence are not. | |
From: Theodore Sider (Writing the Book of the World [2011], 03.4) | |
A reaction: I note that Einstein requires space to be 'curved', which implies that it is a substance with properties. |
15021 | The central question in the philosophy of time is: How alike are time and space? [Sider] |
Full Idea: The central question in the philosophy of time is: How alike are time and space? | |
From: Theodore Sider (Writing the Book of the World [2011], 11.1) |
15024 | The spotlight theorists accepts eternal time, but with a spotlight of the present moving across it [Sider] |
Full Idea: The spotlight theorist accepts the block universe, but also something in addition: a joint-carving monadic property of presentness, which is possessed by just one moment of time, and which 'moves', to be possessed by later and later times. | |
From: Theodore Sider (Writing the Book of the World [2011], 11.9) | |
A reaction: This seems better than the merely detached eternalist view, which seems to ignore the key phenomenon. I just can't comprehend any theory which makes the future as real as the past. |
23341 | God created humans as spectators and interpreters of God's works [Epictetus] |
Full Idea: God has introduced man into the world as a spectator of himself and of his works: and not only as a spectator of them, but an interpreter of them as well. | |
From: Epictetus (The Discourses [c.56], 1.06.19) | |
A reaction: This idea (which strikes me as bizarre) was picked up directly by the Christians. I can't imagine every Johnson wanting to creating their own Boswell. If you think we are divinely created, you have to propose some motive for it, I suppose. |
23348 | Both god and the good bring benefits, so their true nature seems to be the same [Epictetus] |
Full Idea: God brings benefits; but the good also brings benefit. It would seem, then, that where the true nature of god is, there too is the true nature of good. | |
From: Epictetus (The Discourses [c.56], 2.08.01) | |
A reaction: An enthymeme, missing the premise that there can only be one source of benefit (which sounds unlikely). Does god bring anything other than benefits? And does the good? I think this is an idea from later platonism. |
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) |
23360 | Each of the four elements in you is entirely scattered after death [Epictetus] |
Full Idea: Whatever was in you of fire, departs into fire; what was of earth, into earth; what of air, into air; what of water, into water. There is no Hades, nor Acheron. | |
From: Epictetus (The Discourses [c.56], 3.13.15) | |
A reaction: This sort of remark may explain why so few of the great Stoic texts (such as those of Chrysippus) survived the Christian era. |
