From: PG (Db (lexicon) [c.1001 BCE], 02) |
11302 | Aitia / aition: cause, explanation [PG] |
Full Idea: Aitia / aition: cause, explanation | |
From: PG (Db (lexicon) [c.1001 BCE], 03) | |
A reaction: The consensus is that 'explanation' is the better translation, and hence that the famous Four Causes (in 'Physics') must really be understood as the Four Modes of Explanation. They then make far more sense. |
11303 | Akrasia: lack of control, weakness of will [PG] |
Full Idea: Akrasia: lack of control, weakness of will | |
From: PG (Db (lexicon) [c.1001 BCE], 04) | |
A reaction: The whole Greek debate (and modern debate, I would say) makes much more sense if we stick to 'lack of control' as the translation, and forget about weakness of will - and certainly give up 'incontinence' as a translation. |
11304 | Aletheia: truth [PG] |
Full Idea: Aletheia: truth | |
From: PG (Db (lexicon) [c.1001 BCE], 05) |
11305 | Anamnesis: recollection, remembrance [PG] |
Full Idea: Anamnesis: recollection, remembrance | |
From: PG (Db (lexicon) [c.1001 BCE], 06) | |
A reaction: This is used for Plato's doctrine that we recollect past lives. |
11306 | Ananke: necessity [PG] |
Full Idea: Ananke: necessity | |
From: PG (Db (lexicon) [c.1001 BCE], 07) |

From: PG (Db (lexicon) [c.1001 BCE], 10) | |

Full Idea: Aporia: puzzle, question, anomaly | |
From: PG (Db (lexicon) [c.1001 BCE], 13) |
11311 | Arche: first principle, the basic [PG] |
Full Idea: Arché: first principle, the basic | |
From: PG (Db (lexicon) [c.1001 BCE], 14) | |
A reaction: Interchangeable with 'aitia' by Aristotle. The first principle and the cause are almost identical. |
11312 | Arete: virtue, excellence [PG] |
Full Idea: Areté: virtue, excellence | |
From: PG (Db (lexicon) [c.1001 BCE], 15) | |
A reaction: The word hovers between moral excellence and being good at what you do. Annas defends the older translation as 'virtue', rather than the modern 'excellence'. |
11313 | Chronismos: separation [PG] |
Full Idea: Chronismos: separation | |
From: PG (Db (lexicon) [c.1001 BCE], 16) |
11314 | Diairesis: division [PG] |

From: PG (Db (lexicon) [c.1001 BCE], 22) |
11318 | Dikaiosune: moral goodness, justice [PG] |
Full Idea: Dikaiosune: moral goodness, justice | |
From: PG (Db (lexicon) [c.1001 BCE], 23) | |
A reaction: Usually translated as 'justice' in 'Republic', but it is a general term of moral approbation, not like the modern political and legal notion of 'justice'. 'Justice' actually seems to be bad translation. |
11319 | Doxa: opinion, belief [PG] |
Full Idea: Doxa: opinion, belief, judgement | |
From: PG (Db (lexicon) [c.1001 BCE], 24) |
11320 | Dunamis: faculty, potentiality, capacity [PG] |
Full Idea: Dunamis: faculty, potentiality, capacity | |
From: PG (Db (lexicon) [c.1001 BCE], 25) |
11321 | Eidos: form, idea [PG] |
Full Idea: Eidos: form, idea | |
From: PG (Db (lexicon) [c.1001 BCE], 26) | |
A reaction: In Plato it is the word best translated as 'Form' (Theory of...); in Aritotle's 'Categories' it designates the species, and in 'Metaphysics' it ends up naming the structural form of the species (and hence the essence) [Wedin p.120] |
11322 | Elenchos: elenchus, interrogation [PG] |
Full Idea: Elenchos: elenchus, interrogation | |
From: PG (Db (lexicon) [c.1001 BCE], 27) |

Full Idea: Energeia: employment, actuality, power? | |
From: PG (Db (lexicon) [c.1001 BCE], 31) |
11325 | Enkrateia: control [PG] |
Full Idea: Enkrateia: control | |
From: PG (Db (lexicon) [c.1001 BCE], 32) | |
A reaction: See 'akrasia', of which this is the opposite. The enkratic person is controlled. |
11326 | Entelecheia: entelechy, having an end [PG] |
Full Idea: Entelecheia: entelechy, having an end | |
From: PG (Db (lexicon) [c.1001 BCE], 33) |
11327 | Epagoge: induction, explanation [PG] |
Full Idea: Epagoge: induction, explanation, leading on | |
From: PG (Db (lexicon) [c.1001 BCE], 34) |
11328 | Episteme: knowledge, understanding [PG] |
Full Idea: Episteme: knowledge, understanding | |
From: PG (Db (lexicon) [c.1001 BCE], 35) | |
A reaction: Note that 'episteme' can form a plural in Greek, but we can't say 'knowledges', so we have to say 'branches of knowledge', or 'sciences'. |
11329 | Epithumia: appetite [PG] |
Full Idea: Epithumia: appetite | |
From: PG (Db (lexicon) [c.1001 BCE], 36) |
11330 | Ergon: function [PG] |
Full Idea: Ergon: function, work | |
From: PG (Db (lexicon) [c.1001 BCE], 37) |
11331 | Eristic: polemic, disputation [PG] |
Full Idea: Eristic: polemic, disputation | |
From: PG (Db (lexicon) [c.1001 BCE], 38) | |
A reaction: This is confrontational argument, rather than the subtle co-operative dialogue of dialectic. British law courts and the House of Commons are founded on eristic, rather than on dialectic. Could there be a dialectical elected assembly? |
11332 | Eros: love [PG] |
Full Idea: Eros: love, desire | |
From: PG (Db (lexicon) [c.1001 BCE], 41) |
11333 | Eudaimonia: flourishing, happiness, fulfilment [PG] |
Full Idea: Eudaimonia: flourishing, happiness, fulfilment | |
From: PG (Db (lexicon) [c.1001 BCE], 42) | |
A reaction: Some people defend 'happiness' as the translation, but that seems to me wildly misleading, since eudaimonia is something like life going well, and certainly isn't a psychological state - and definitely not pleasure. |
11334 | Genos: type, genus [PG] |
Full Idea: Genos: type, genus, kind | |
From: PG (Db (lexicon) [c.1001 BCE], 43) |
11335 | Hexis: state, habit [PG] |
Full Idea: Hexis: state, habit | |
From: PG (Db (lexicon) [c.1001 BCE], 44) |
11336 | Horismos: definition [PG] |
Full Idea: Horismos: definition | |
From: PG (Db (lexicon) [c.1001 BCE], 45) |
11337 | Hule: matter [PG] |
Full Idea: Hule: matter | |
From: PG (Db (lexicon) [c.1001 BCE], 46) | |
A reaction: The first half of the 'hylomorphism' of Aristotle. See 'morphe'! |
11338 | Hupokeimenon: subject, underlying thing [cf. Tode ti] [PG] |
Full Idea: Hupokeimenon: subject, underlying thing, substratum [cf. Tode ti] | |
From: PG (Db (lexicon) [c.1001 BCE], 47) | |
A reaction: Literally 'that which lies under'. Latin version is 'substratum'. In Aristotle it is the problem, of explaining what lies under. It is not the theory that there is some entity called a 'substratum'. |
11339 | Kalos / kalon: beauty, fineness, nobility [PG] |
Full Idea: Kalos / kalon: beauty, fineness, nobility | |
From: PG (Db (lexicon) [c.1001 BCE], 48) | |
A reaction: A revealing Greek word, which is not only our rather pure notion of 'beauty', but also seems to mean something like wow!, and (very suggestive, this) applies as much to actions as to objects. |
11340 | Kath' hauto: in virtue of itself, essentially [PG] |
Full Idea: Kath' hauto: in virtue of itself, essentially | |
From: PG (Db (lexicon) [c.1001 BCE], 51) |

Full Idea: Logos: reason, account, word | |
From: PG (Db (lexicon) [c.1001 BCE], 54) |
11344 | Meson: the mean [PG] |
Full Idea: Meson: the mean | |
From: PG (Db (lexicon) [c.1001 BCE], 55) | |
A reaction: This is not the 'average', and hence not some theoretical mid-point. I would call it the 'appropriate compromise', remembering that an extreme may be appropriate in certain circumstances. |
11345 | Metechein: partaking, sharing [PG] |
Full Idea: Metechein: partaking, sharing | |
From: PG (Db (lexicon) [c.1001 BCE], 56) | |
A reaction: The key word in Plato for the difficult question of the relationships between the Forms and the particulars. The latter 'partake' of the former. Hm. Compare modern 'instantiation', which strikes me as being equally problematic. |
11377 | Mimesis: imitation, fine art [PG] |
Full Idea: Mimesis: imitation, fine art | |
From: PG (Db (lexicon) [c.1001 BCE], 57) |
11346 | Morphe: form [PG] |

From: PG (Db (lexicon) [c.1001 BCE], 58) |

11348 | Nomos: convention, law, custom [PG] |
Full Idea: Nomos: convention, law, custom | |
From: PG (Db (lexicon) [c.1001 BCE], 61) |
11349 | Nous: intuition, intellect, understanding [PG] |
Full Idea: Nous: intuition, intellect | |
From: PG (Db (lexicon) [c.1001 BCE], 62) | |
A reaction: There is a condensed discussion of 'nous' in Aristotle's Posterior Analytics B.19 |
11350 | Orexis: desire [PG] |
Full Idea: Orexis: desire | |
From: PG (Db (lexicon) [c.1001 BCE], 63) |
11351 | Ousia: substance, (primary) being, [see 'Prote ousia'] [PG] |
Full Idea: Ousia: substance, (primary) being [see 'Prote ousia'] | |
From: PG (Db (lexicon) [c.1001 BCE], 64) | |
A reaction: It is based on the verb 'to be'. Latin therefore translated it as 'essentia' (esse: to be), and we have ended up translating it as 'essence', but this is wrong! 'Being' is the best translation, and 'substance' is OK. It is the problem, not the answer. |
11352 | Pathos: emotion, affection, property [PG] |
Full Idea: Pathos: emotion, affection, property | |
From: PG (Db (lexicon) [c.1001 BCE], 65) |
11353 | Phantasia: imagination [PG] |
Full Idea: Phantasia: imagination | |
From: PG (Db (lexicon) [c.1001 BCE], 66) |
11354 | Philia: friendship [PG] |
Full Idea: Philia: friendship | |
From: PG (Db (lexicon) [c.1001 BCE], 67) |
11355 | Philosophia: philosophy, love of wisdom [PG] |
Full Idea: Philosophia: philosophy, love of wisdom | |
From: PG (Db (lexicon) [c.1001 BCE], 68) | |
A reaction: The point of the word is its claim only to love wisdom, and not actually to be wise. |
11356 | Phronesis: prudence, practical reason, common sense [PG] |
Full Idea: Phronesis: prudence, practical reason, common sense | |
From: PG (Db (lexicon) [c.1001 BCE], 71) | |
A reaction: None of the experts use my own translation, which is 'common sense', but that seems to me to perfectly fit all of Aristotle's discussions of the word in 'Ethics'. 'Prudence' seems a daft translation in modern English. |
11357 | Physis: nature [PG] |
Full Idea: Physis: nature | |
From: PG (Db (lexicon) [c.1001 BCE], 72) |
11358 | Praxis: action, activity [PG] |
Full Idea: Praxis: action, activity | |
From: PG (Db (lexicon) [c.1001 BCE], 73) |
11359 | Prote ousia: primary being [PG] |
Full Idea: Prote ousia: primary being | |
From: PG (Db (lexicon) [c.1001 BCE], 74) | |
A reaction: The main topic of investigation in Aristotle's 'Metaphysics'. 'Ousia' is the central problem of the text, NOT the answer to the problem. |
11360 | Psuche: mind, soul, life [PG] |
Full Idea: Psuche: mind, soul, life | |
From: PG (Db (lexicon) [c.1001 BCE], 75) | |
A reaction: The interesting thing about this is that we have tended to translate it as 'soul', but Aristotle says plants have it, and not merely conscious beings. It is something like the 'form' of a living thing, but then 'form' is a misleading translation too. |
11361 | Sophia: wisdom [PG] |
Full Idea: Sophia: wisdom | |
From: PG (Db (lexicon) [c.1001 BCE], 76) |
11362 | Sophrosune: moderation, self-control [PG] |

Full Idea: Sullogismos: deduction, syllogism | |
From: PG (Db (lexicon) [c.1001 BCE], 81) |

From: PG (Db (lexicon) [c.1001 BCE], 86) |
11370 | Timoria: vengeance, punishment [PG] |
Full Idea: Timoria: vengeance, punishment | |
From: PG (Db (lexicon) [c.1001 BCE], 87) |
11371 | To ti en einai: essence, what-it-is-to-be [PG] |
Full Idea: To ti en einai: essence, what-it-is-to-be | |
From: PG (Db (lexicon) [c.1001 BCE], 88) | |
A reaction: This is Aristotle's main term for what we would now call the 'essence'. It is still not a theory of essence, merely an identification of the target. 'Form' is the nearest we get to his actual theory. |
11372 | To ti estin: essence [PG] |
Full Idea: To ti estin: essence | |
From: PG (Db (lexicon) [c.1001 BCE], 91) |

12027 | There must be a plausible epistemological theory alongside any metaphysical theory [Forbes,G] |
Full Idea: No metaphysical account which renders it impossible to give a plausible epistemological theory is to be countenanced. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.1) | |
A reaction: It is hard to object to this principle, though we certainly don't want to go verificationist, and thus rule out speculations about metaphysics which are beyond any possible knowledge. Some have tried to prove that something must exist (e.g. Jacquette). |
4465 | Note that "is" can assert existence, or predication, or identity, or classification [PG] |

From: PG (Db (ideas) [2031]) | |
A reaction: This seems a nice instance of the sort of point made by analytical philosophy, which can lead to horrible confusion in other breeds of philosophy when it is overlooked. |

7415 | Question-begging assumes the proposition which is being challenged [PG] |
Full Idea: To beg the question is to take for granted in your argument that very proposition which is being challenged | |
From: PG (Db (ideas) [2031]) | |
A reaction: An undoubted fallacy, and a simple failure to engage in the rational enterprise. I suppose one might give a reason for something, under the mistaken apprehension that it didn't beg the question; analysis of logical form is then needed. |
7414 | What is true of a set is also true of its members [PG] |
Full Idea: The fallacy of division is the claim that what is true of a set must therefore be true of its members. | |
From: PG (Db (ideas) [2031]) | |

From: PG (Db (ideas) [2031]) | |
A reaction: Nietzsche is very keen on ad hominem arguments, and cheerfully insults great philosophers, but then he doesn't believe there is such a thing as 'pure argument', and he is a relativist. |
4687 | Minimal theories of truth avoid ontological commitment to such things as 'facts' or 'reality' [PG] |
Full Idea: Minimalist theories of truth are those which involve minimum ontological commitment, avoiding references to 'reality' or 'facts' or 'what works', preferring to refer to formal relationships within language. | |
From: PG (Db (ideas) [2031]) | |
A reaction: Personally I am suspicious of minimal theories, which seem to be designed by and for anti-realists. They seem too focused on language, when animals can obviously formulate correct propositions. I'm quite happy with the 'facts', even if that is vague. |
12005 | The symbol 'ι' forms definite descriptions; (ιx)F(x) says 'the x which is such that F(x)' [Forbes,G] |
Full Idea: We use the symbol 'ι' (Greek 'iota') to form definite descriptions, reading (ιx)F(x) as 'the x which is such that F(x)', or simply as 'the F'. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.1) | |
A reaction: Compare the lambda operator in modal logic, which picks out predicates from similar formulae. |
12010 | Is the meaning of 'and' given by its truth table, or by its introduction and elimination rules? [Forbes,G] |
Full Idea: The typical semantic account of validity for propositional connectives like 'and' presupposes that meaning is given by truth-tables. On the natural deduction view, the meaning of 'and' is given by its introduction and elimination rules. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.4) |
6516 | Monty Hall Dilemma: do you abandon your preference after Monty eliminates one of the rivals? [PG] |
Full Idea: The Monty Hall Dilemma: Three boxes, one with a big prize; pick one to open. Monty Hall then opens one of the other two, which is empty. You may, if you wish, switch from your box to the other unopened box. Should you? | |

A reaction: The other two boxes, as a pair, are more likely contain the prize than your box. Monty Hall has eliminated one of them for you, so you should choose the other one. Your intuition that the two remaining boxes are equal is incorrect! |
12023 | Vagueness problems arise from applying sharp semantics to vague languages [Forbes,G] |
Full Idea: It is very plausible that the sorites paradoxes arose from the application of a semantic apparatus appropriate only for sharp predicates to languages containing vague predicates (rather than from deficiency of meaning, or from incoherence). | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.3) | |
A reaction: Sounds wrong. Of course, logic has been designed for sharp predicates, and natural languages are awash with vagueness. But the problems of vagueness bothered lawyers long before logicians like Russell began to worry about it. |
12017 | In all instances of identity, there must be some facts to ensure the identity [Forbes,G] |
Full Idea: For each instance of identity or failure of identity, there must be facts in virtue of which that instance obtains. ..Enough has been said to lend this doctrine some plausibility. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.5) | |
A reaction: Penelope Mackie picks this out from Forbes as a key principle. It sounds to be in danger of circularity, unless the 'facts' can be cited without referring to, or implicitly making use of, identities - which seems unlikely. |
12024 | If we combined two clocks, it seems that two clocks may have become one clock. [Forbes,G] |
Full Idea: If we imagine a possible world in which two clocks in a room make one clock from half the parts of each, the judgement 'these two actual clocks could have been a single clock' does not seem wholly false. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.4) | |
A reaction: You would, of course, have sufficient parts left over to make a second clock, so they look like a destroyed clock, so I don't think I find Forbes's intuition on this one very persuasive. |
11885 | Only individual essences will ground identities across worlds in other properties [Forbes,G, by Mackie,P] |
Full Idea: Forbes argues that, unless we posit individual essences, we cannot guarantee that identities across possible worlds will be appropriately grounded in other properties. | |
From: report of Graeme Forbes (The Metaphysics of Modality [1985]) by Penelope Mackie - How Things Might Have Been 2.4 | |
A reaction: There is a confrontation between Wiggins, who says identity is primitive, and Forbes, who says identity must be grounded in other properties. I think I side with Forbes. |
12014 | An individual essence is a set of essential properties which only that object can have [Forbes,G] |
Full Idea: An individual essence of an object x is a set of properties I which satisfies the following conditions: i. every property P in I is an essential property of x; ii. it is not possible that some object y distinct from x has every member of I. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I am coming to the view that stable natural kinds (like electrons or gold) do not have individual essences, but complex kinds (like tigers or tables) do. The view is based on the idea that explanatory power is what individuates an essence. |
12015 | Non-trivial individual essence is properties other than de dicto, or universal, or relational [Forbes,G] |
Full Idea: A non-trivial individual essence is properties other than a) those following from a de dicto truth, b) properties of existence and self-identity (or their cognates), c) properties derived from necessities in some other category. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: [I have compressed Forbes] Rather than adding all these qualificational clauses to our concept, we could just tighten up on the notion of a property, saying it is something which is causally efficacious, and hence explanatory. |
12013 | Essential properties depend on a category, and perhaps also on particular facts [Forbes,G] |
Full Idea: The essential properties of a thing will typically depend upon what category of thing it is, and perhaps also on some more particular facts about the thing itself. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I see no way of dispensing with the second requirement, in the cases of complex entities like animals. If all samples are the same, then of course we can define a sample's essence through its kind, but not if samples differ in any way. |
13804 | A property is essential iff the object would not exist if it lacked that property [Forbes,G] |
Full Idea: A property P is an essential property of an object x iff x could not exist and lack P, that is, as they say, iff x has P at every world at which x exists. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 1) | |
A reaction: This immediately places the existence of x outside the normal range of its properties, so presumably 'existence is not a predicate', but that dictum may be doubted. As it stands this definition will include trivial and vacuous properties. |
13805 | Properties are trivially essential if they are not grounded in a thing's specific nature [Forbes,G] |
Full Idea: Essential properties may be trivial or nontrivial. It is characteristic of P's being trivially essential to x that x's possession of P is not grounded in the specific nature of x. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: This is where my objection to the modal view of essence arises. How is he going to explain 'grounded' and 'specific nature' without supplying an entirely different account of essence? |
12012 | Essential properties are those without which an object could not exist [Forbes,G] |
Full Idea: An essential property of an object x is a property without possessing which x could not exist. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: This is certainly open to question. See Joan Kung's account of Aristotle on essence. I am necessarily more than eight years old (now), and couldn't exist without that property, but is the property part of my essence? |
13808 | A relation is essential to two items if it holds in every world where they exist [Forbes,G] |
Full Idea: A relation R is essential to x and y (in that order) iff Rxy holds at every world where x and y both exist. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: I find this bizarre. Not only does this seem to me to have nothing whatever to do with essence, but also the relation might hold even though it is a purely contingent matter. All rabbits are a reasonable distance from the local star. Essence of rabbit? |
13806 | Trivially essential properties are existence, self-identity, and de dicto necessities [Forbes,G] |
Full Idea: The main groups of trivially essential properties are (a) existence, self-identity, or their consequences in S5; and (b) properties possessed in virtue of some de dicto necessary truth. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: He adds 'extraneously essential' properties, which also strike me as being trivial, involving relations. 'Is such that 2+2=4' or 'is such that something exists' might be necessary, but they don't, I would say, have anything to do with essence. |
13807 | A property is 'extraneously essential' if it is had only because of the properties of other objects [Forbes,G] |
Full Idea: P is 'extraneously essential' to x iff it is possessed by x at any world w only in virtue of the possession at w of certain properties by other objects. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 2) | |
A reaction: I would say that these are the sorts of properties which have nothing to do with being essential, even if they are deemed to be necessary. |
12022 | Same parts does not ensure same artefact, if those parts could constitute a different artefact [Forbes,G] |
Full Idea: Sameness of parts is not sufficient for identity of artefacts at a world, since the very same parts may turn up at different times as the parts of artefacts with different designs and functions. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.2) | |
A reaction: Thus the Ship of Theseus could be dismantled and turned into a barn (as happened with the 'Mayflower'). They could then be reconstituted as the ship, which would then have two beginnings (as Chris Hughes has pointed out). |
12025 | Artefacts have fuzzy essences [Forbes,G] |
Full Idea: Artefacts can be ascribed fuzzy essences. ...We might say that it is essential to an artefact to have 'most' of its parts. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 7.6) | |
A reaction: I think I prefer to accept the idea that essences are unstable things, in all cases. For all we know, electrons might subtly change their general character, or cease to be uniform, tomorrow. Essences explain, and what needs explaining changes. |
13809 | One might be essentialist about the original bronze from which a statue was made [Forbes,G] |
Full Idea: In the case of artefacts, there is an essentialism about original matter; for instance, it would be said of any particular bronze statue that it could not have been cast from a totally different quantity of bronze. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 3) | |
A reaction: Forbes isn't endorsing this, and it doesn't sound convincing. He quotes the thought 'I wish I had made this pot from a different piece of clay'. We might corrupt a statue by switching bronze, but I don't think the sculptor could do so. |
12020 | An individual might change their sex in a world, but couldn't have differed in sex at origin [Forbes,G] |
Full Idea: In the time of a single world, the same individual can undergo a change of sex, but it is less clear that an individual of one sex could have been, from the outset, an individual of another. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 6.5) | |
A reaction: I don't find this support for essentiality of origin very persuasive. I struggle with these ideas. Given my sex yesterday, then presumably I couldn't have had a different sex yesterday. Given that pigs can fly, pigs can fly. What am I missing? |
11888 | Identities must hold because of other facts, which must be instrinsic [Forbes,G, by Mackie,P] |
Full Idea: Forbes has two principles of identity, which we can call the No Bare Identities Principle (identities hold in virtue of other facts), and the No Extrinsic Determination Principle (that only intrinsic facts of a thing establish identity). | |
From: report of Graeme Forbes (The Metaphysics of Modality [1985], 127-8) by Penelope Mackie - How Things Might Have Been 2.7 | |
A reaction: The job of the philosopher is to prise apart the real identities of things from the way in which we conceive of identities. I take these principles to apply to real identities, not conceptual identities. |
12003 | De re modal formulae, unlike de dicto, are sensitive to transworld identities [Forbes,G] |
Full Idea: The difference between de re and de dicto formulae is a difference between formulae which are, and formulae which are not, sensitive to the identities of objects at various worlds. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 3.1) |
24054 | Everything has a probability, something will happen, and probabilities add up [PG] |
Full Idea: The three Kolgorov axioms of probability: the probability of an event is a non-negative real number; it is certain that one of the 'elementary events' will occur; and the unity of probabilities is the sum of probability of parts ('additivity'). | |
From: PG (Db (ideas) [2031]) | |
A reaction: [My attempt to verbalise them; they are normally expressed in terms of set theory]. Got this from a talk handout, and Wikipedia. |
12028 | De re necessity is a form of conceptual necessity, just as de dicto necessity is [Forbes,G] |
Full Idea: De re necessity does not differ from de dicto necessity in respect of how it arises: it is still a form of conceptual necessity. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.4) | |
A reaction: [Forbes proceeds to argue for this claim] Forbes defends a form of essentialism, but takes the necessity to arise from a posteriori truths because of the a priori involvement of other concepts (rather as Kripke argues). |
13810 | The source of de dicto necessity is not concepts, but the actual properties of the thing [Forbes,G] |
Full Idea: It is widely held that the source of de dicto necessity is in concepts, ..but I deny this... even with simple de dicto necessities, the source of the necessity is to be found in the properties to which the predicates of the de dicto truth refer. | |
From: Graeme Forbes (In Defense of Absolute Essentialism [1986], 3) | |
A reaction: It is normal nowadays to say this about de re necessities, but this is more unusual. |
12008 | Unlike places and times, we cannot separate possible worlds from what is true at them [Forbes,G] |
Full Idea: There is no means by which we might distinguish a possible world from what is true at it. ...Whereas our ability to separate a place, or a time, from its occupier is crucial to realism about places and times, as is a distance relation. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: He is objecting to Lewis's modal realism. I'm not fully convinced. It depends whether we are discussing real ontology or conceptual space. In the latter I see no difference between times and possible worlds. In ontology, a 'time' is weird. |
12009 | The problem with possible worlds realism is epistemological; we can't know properties of possible objects [Forbes,G] |
Full Idea: The main objection to realism about worlds is from epistemology. Knowledge of properties of objects requires experience of these objects, which must be within the range of our sensory faculties, but only concrete actual objects achieve that. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: This pinpoints my dislike of the whole possible worlds framework, ontologically speaking. I seem to be an actualist. I take possibilities to be inferences to the best explanation from the powers we know of in the actual world. We experience potentiality. |
12007 | Possible worlds are points of logical space, rather like other times than our own [Forbes,G] |
Full Idea: Someone impressed by the parallel between tense and modal operators ...might suggest that just as we can speak of places and times forming their own manifolds or spaces, so we can say that worlds are the points of logical space. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 4.2) | |
A reaction: I particularly like the notion of worlds being "points of logical space", and am inclined to remove it from this context and embrace it as the correct way to understand possible worlds. We must understand logical or conceptual space. |
12011 | Transworld identity concerns the limits of possibility for ordinary things [Forbes,G] |
Full Idea: An elucidation of transworld identity can be regarded as an elucidation of the boundaries of possibility for ordinary things. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: I presume that if we don't search for some such criterion, we just have to face the possibility that Aristotle could have been a poached egg in some possible world. To know the bounds of possibility, study the powers of actual objects. |
12016 | The problem of transworld identity can be solved by individual essences [Forbes,G] |
Full Idea: The motivation for investigating individual essences should be obvious, since if every object has such an essence, the problem of elucidating transworld identity can be solved. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 5.1) | |
A reaction: It is important that, if necessary, the identities be 'individual', and not just generic, by sortal, or natural kind. We want to reason about (and explain) truths at the fine-grained level of the individual, not just at the broad level of generalisation. |
12004 | Counterpart theory is not good at handling the logic of identity [Forbes,G] |
Full Idea: The outstanding technical objection to counterpart-theoretic semantics concerns its handling of the logic of identity. In quantified S5 (the orthodox semantics) a = b → □(a = b) is valid, but 'a' must not attach to two objects. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 3.5) |
12021 | Haecceitism attributes to each individual a primitive identity or thisness [Forbes,G] |
Full Idea: Haecceitism attributes to each individual a primitive identity or thisness, as opposed to the sort of essentialism that gives non-trivial conditions sufficient for transworld identity. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 6.6) | |
A reaction: 'Haecceitism' is the doctrine that things have primitive identity. A 'haecceity' is a postulated property which actually does the job. The key point of the view is that whatever it is is 'primitive', and not complex, or analysable. I don't believe it. |
12029 | We believe in thisnesses, because we reject bizarre possibilities as not being about that individual [Forbes,G] |
Full Idea: The natural response to an unreasonable hypothesis of possibility for an object x, that in such a state of affairs it would not be x which satisfies the conditions, is evidence that we do possess concepts of thisness for individuals. | |
From: Graeme Forbes (The Metaphysics of Modality [1985], 9.4) | |
A reaction: We may have a 'concept' of thisness, but we needn't be committed to the 'existence' of a thisness. There is a fairly universal intuition that cessation of existence of an entity when it starts to change can be a very vague matter. |
3875 | If reality is just what we perceive, we would have no need for a sixth sense [PG] |
Full Idea: Reality must be more than merely what we perceive, because a sixth sense would enhance our current knowledge, and a seventh, and so on. | |
From: PG (Db (ideas) [2031]) |
3876 | If my team is losing 3-1, I have synthetic a priori knowledge that they need two goals for a draw [PG] |
Full Idea: If my football team is losing 3-1, I seem to have synthetic a priori knowledge that they need two goals to achieve a draw | |
From: PG (Db (ideas) [2031]) |
7734 | Maybe a mollusc's brain events for pain ARE of the same type (broadly) as a human's [PG] |
Full Idea: To defend type-type identity against the multiple realisability objection, we might say that a molluscs's brain events that register pain ARE of the same type as humans, given that being 'of the same type' is a fairly flexible concept. | |
From: PG (Db (ideas) [2031]) | |
A reaction: But this reduces 'of the same type' to such vagueness that it may become vacuous. You would be left with token-token identity, where the mental event is just identical to some brain event, with its 'type' being irrelevant. |
7735 | Maybe a frog's brain events for fear are functionally like ours, but not phenomenally [PG] |
Full Idea: To defend type-type identity against the multiple realisability objection, we might (also) say that while a frog's brain events for fear are functionally identical to a human's (it runs away), that doesn't mean they are phenomenally identical. | |
From: PG (Db (ideas) [2031]) | |
A reaction: I take this to be the key reply to the multiple realisability problem. If a frog flees from a loud noise, it is 'frightened' in a functional sense, but that still leaves the question 'What's it like to be a frightened frog?', which may differ from humans. |
3877 | Utilitarianism seems to justify the discreet murder of unhappy people [PG] |
Full Idea: If I discreetly murdered a gloomy and solitary tramp who was upsetting people in my village, if is hard to see how utilitarianism could demonstrate that I had done something wrong. | |
From: PG (Db (ideas) [2031]) |
5064 | Rights are moral significance, or liberty, or right not to be restrained, or entitlement [Mawson] |
Full Idea: A 'right' can mean 'x counts morally', or 'x is permitted to do this' (liberty), or 'x can't be stopped from doing this' (negative right), or 'someone should provide this for x'. | |
From: Tim Mawson (Animal Rights talk [2003]), quoted by PG - lecture notes | |
A reaction: A useful analysis. It is a useful preliminary to considering whether any of these are natural rights. Personally I am sympathetic to that concept. You cannot deny a person's right to self-defence, even when you are sitting on them. Persons have rights. |
6126 | Life is Movement, Respiration, Sensation, Nutrition, Excretion, Reproduction, Growth (MRS NERG) [PG] |
Full Idea: The biologists' acronym for the necessary conditions of life is MRS NERG: that is, Movement, Respiration, Sensation, Nutrition, Excretion, Reproduction, Growth. | |
From: PG (Db (ideas) [2031]) | |
A reaction: How strictly necessary are each of these is a point for discussion. A notorious problem case is fire, which (at a stretch) may pass all seven tests. |
3873 | An omniscient being couldn't know it was omniscient, as that requires information from beyond its scope of knowledge [PG] |
Full Idea: God seems to be in the paradoxical situation that He may be omniscient, but can never know that He is, because that involves knowing that there is nothing outside his scope of knowledge (e.g. another God) | |
From: PG (Db (ideas) [2031]) |
3874 | How could God know there wasn't an unknown force controlling his 'free' will? [PG] |
Full Idea: How could God be certain that he has free will (if He has), if He couldn't be sure that there wasn't an unknown force controlling his will? | |
From: PG (Db (ideas) [2031]) |
