| 2930 | The main aim of philosophy must be to determine the order of rank among values [Nietzsche] |
| Full Idea: The future task of the philosophers is the solution of the problem of value, the determination of the order of rank among values. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§17 note) | |
| A reaction: 'Determine' is presumably either a power struggle, or needs criteria by which to do the judging. |
| 20143 | Scientific knowledge is nothing without a prior philosophical 'faith' [Nietzsche] |
| Full Idea: Strictly speaking there is no knowledge [science] without presuppositions; a philosophy, a 'faith', must always be there first of all, for knowledge to win from it a direction, a meaning, a limit, a method, a right to exist. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§24) | |
| A reaction: He sees philosophers as the creators of this faith, and laughs at anyone who tries to set philosophy on a scientific basis. |
| 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) |
| 23722 | Objectivity is not disinterestedness (impossible), but the ability to switch perspectives [Nietzsche] |
| Full Idea: 'Objectivity' should be understood not as 'contemplation without interest' (a non-concept and an absurdity), but as having in our power the ability to engage and disengage our 'pros' and 'cons'; we can use the difference in perspectives for knowledge. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§12) | |
| A reaction: Note that he will use perspectives to achieve knowledge. The idea that Perspectivalism is mere relativism is labelled as 'extreme' in Idea 4486. He is right that objectivity is a mental capacity and achievement of individuals. |
| 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. |
| 4417 | Only that which has no history is definable [Nietzsche] |
| Full Idea: Only that which has no history is definable. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§13) | |
| A reaction: Too subtle to evaluate! It sounds as if it could be right, that some things are definable, but when the accretions of human history are interwoven into an identity, we can forget it. |
| 19023 | Slippery slope arguments are challenges to show where a non-arbitrary boundary lies [Vetter] |
| Full Idea: Slippery slope arguments are not intended as demonstrative arguments, but rather as a challenge to show where a boundary is, and to show that the boundary is not arbitrary. | |
| From: Barbara Vetter (Potentiality [2015], 5.3.3) | |
| A reaction: [extracted from details of its context] You could respond by saying that a slippery slope levels off, rather than hitting a wall or plunging to perdition. |
| 23715 | Psychologists should be brave and proud, and prefer truth to desires, even when it is ugly [Nietzsche] |
| Full Idea: I hope [psychologists] are actually brave, generous, proud animals, who know how to control their own pleasure and pain and are taught to sacrifice desirability to truth, even a bitter, ugly, unchristian, immoral truth - Because there are such truths. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§01) | |
| A reaction: A nice expression of Nietzsche's values, which makes truth central, contrary to the widespread modern view that he was the high priest of relativism. If you think that, read him more carefully. |
| 19033 | Deontic modalities are 'ought-to-be', for sentences, and 'ought-to-do' for predicates [Vetter] |
| Full Idea: Deontic modality can be divided into sentence-modifying 'ought-to-be' modals, and predicate-modifying 'ought-to-do' modals. | |
| From: Barbara Vetter (Potentiality [2015], 6.9.2) | |
| A reaction: [She cites Brennan 1993] These two seem to correspond to what is 'good' (ought to be), and what is 'right' (ought to do). Since I like that distinction, I also like this one. |
| 19032 | S5 is undesirable, as it prevents necessities from having contingent grounds [Vetter] |
| Full Idea: Wedgwood (2007:220) argues that S5 is undesirable because it excludes that necessary truths may have contingent grounds. | |
| From: Barbara Vetter (Potentiality [2015], 6.4 n5) | |
| A reaction: Cameron defends the possibility of necessity grounded in contingency, against Blackburn's denial of it. It's interesting that we choose the logic on the basis of the metaphysics. Shouldn't there be internal reasons for a logic's correctness? |
| 19036 | The Barcan formula endorses either merely possible things, or makes the unactualised impossible [Vetter] |
| Full Idea: Subscribers to the Barcan formula must either be committed to the existence of mere possibilia (such as possible unicorns), or deny many unactualised possibilities of existence. | |
| From: Barbara Vetter (Potentiality [2015], 7.5) | |
| A reaction: It increasingly strikes me that the implications of the Barcan formula are ridiculous. Williamson is its champion, but I'm blowed if I can see why. What could a possible unicorn be like? Without them, must we say unicorns are impossible? |
| 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. |
| 19034 | The world is either a whole made of its parts, or a container which contains its parts [Vetter] |
| Full Idea: We can think of the world as a 'whole' that has everything as its parts, like raisins in a cake, or we can think of the world as a 'container', which is disjoint from everything there is, like a bottle containing water. | |
| From: Barbara Vetter (Potentiality [2015], 7.3) | |
| A reaction: [compressed] Space and time seem to have a special role here, and it is hard to think of any other candidates for being the 'container'. I think I will apply my 'what's it made of' test to ontology, and opt for the world as a 'whole'. |
| 229 | The one was and is and will be and was becoming and is becoming and will become [Plato] |
| Full Idea: The one was and is and will be and was becoming and is becoming and will become. | |
| From: Plato (Parmenides [c.364 BCE], 155d) |
| 21821 | Plato's Parmenides has a three-part theory, of Primal One, a One-Many, and a One-and-Many [Plato, by Plotinus] |
| Full Idea: The Platonic Parmenides is more exact [than Parmenides himself]; the distinction is made between the Primal One, a strictly pure Unity, and a secondary One which is a One-Many, and a third which is a One-and-Many. | |
| From: report of Plato (Parmenides [c.364 BCE]) by Plotinus - The Enneads 5.1.08 | |
| A reaction: Plotinus approves of this three-part theory. Parmenides has the problem that the highest Being contains no movement. By placing the One outside Being you can give it powers which an existent thing cannot have. Cf the concept of God. |
| 19015 | Grounding can be between objects ('relational'), or between sentences ('operational') [Vetter] |
| Full Idea: 'Relational' grounding is between entities, best expressed by the two-place predicate 'x grounds y'. 'Operational' grounding is between sentences, best expressed by the two-place sentence operator read as 'because of' or 'in virtue of'. | |
| From: Barbara Vetter (Potentiality [2015], 1.6) |
| 19012 | The Humean supervenience base entirely excludes modality [Vetter] |
| Full Idea: Humean supervenience excludes modality - the whole modal package - from the supervenience base. The Humean world is, at root, thoroughly non-modal. | |
| From: Barbara Vetter (Potentiality [2015], 1.2) | |
| A reaction: This sums up my problem with David Lewis with perfect clarity. He is just excessively empirical. Hume himself also excluded modality from the basic impressions. Locke allows powerful essences (even if they are well hidden). |
| 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) |
| 19024 | A determinate property must be a unique instance of the determinable class [Vetter] |
| Full Idea: The crucial feature of the determinates / determinables relation is that to possess the determinable property, an object must possess exactly one of the determinate properties. | |
| From: Barbara Vetter (Potentiality [2015], 5.7.2) | |
| A reaction: This sounds like a determinable being a function, and the determinate being its output. If 'scarlet' is a determinate of the determinables 'red' or 'coloured', it is not obvious that there is only one possible shade of scarlet. This schema oversimplifies. |
| 19021 | I have an 'iterated ability' to learn the violin - that is, the ability to acquire that ability [Vetter] |
| Full Idea: I do not have the ability to play the violin. Nor does my desk. Unlike my desk, however, I possess the ability to learn to play the violin - the ability, that is, to acquire the ability to play the violin. I have an 'iterated ability' to play the violin. | |
| From: Barbara Vetter (Potentiality [2015], 4.6) | |
| A reaction: An important idea, though the examples are more likely to come from human behaviour than from the non-human physical world. |
| 19016 | We should think of dispositions as 'to do' something, not as 'to do something, if ....' [Vetter] |
| Full Idea: We should think in terms of dispositions in terms of the manifestation alone - not as a disposition to ...if..., but as a disposition to ..., full stop. | |
| From: Barbara Vetter (Potentiality [2015], 1.7) | |
| A reaction: This way of individuating dispositions seems plausible. Some dispositions only have one trigger, but others have many. All sorts of things are inclined to trigger a human smile, but we are just disposed to smile. Some people smile at disasters. |
| 19017 | Nomological dispositions (unlike ordinary ones) have to be continually realised [Vetter] |
| Full Idea: Nomological dispositions such as electric charge seem different from ordinary dispositions. A particle's being electrically charged is not just a possibility of exerting a certain force. Rather, the particle has to exert a force in certain circumstances. | |
| From: Barbara Vetter (Potentiality [2015], 2.7) | |
| A reaction: I can only pull when there is something to pull, but a magnet seems to have a 'field' of attraction which is pullish in character. Does it detect something to pull (like a monad)? Can there be a force which has no object? |
| 19014 | How can spatiotemporal relations be understood in dispositional terms? [Vetter] |
| Full Idea: Spatiotemporal relations are a prime example of properties that are difficult to understand in dispositional terms. | |
| From: Barbara Vetter (Potentiality [2015], 1.6) | |
| A reaction: [Vetter refers to A.Bird 2007 Ch.8 for an attempt] One approach would be to question whether they are 'properties'. I don't think of relations as properties, even if they are predicates. Is space a property of something? |
| 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) |
| 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) |
| 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) |
| 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) |
| 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. |
| 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) |
| 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) |
| 212 | The whole idea of each Form must be found in each thing which participates in it [Plato] |
| Full Idea: The whole idea of each form (of beauty, justice etc) must be found in each thing which participates in it. | |
| From: Plato (Parmenides [c.364 BCE], 131a) |
| 215 | If things partake of ideas, this implies either that everything thinks, or that everything actually is thought [Plato] |
| Full Idea: If all things partake of ideas, must either everything be made of thoughts and everything thinks, or everything is thought, and so can't think? | |
| From: Plato (Parmenides [c.364 BCE], 132c) |
| 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) |
| 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) |
| 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. |
| 19030 | Why does origin matter more than development; why are some features of origin more important? [Vetter] |
| Full Idea: Not every feature of an individual's origin is plausibly considered necessary, so we can distinguish two questions: 'why origin, rather than development?', and 'why these particular features of origin?'. | |
| From: Barbara Vetter (Potentiality [2015], 6.2) | |
| A reaction: [she cites P. Mackie 1998] The point is that exactly where someone was born doesn't seem vital. If it is nothing more than that every contingent object must have an origin, that is not very exciting. |
| 19040 | We take origin to be necessary because we see possibilities as branches from actuality [Vetter] |
| Full Idea: The plausibility of the necessity of origin is a symptom of our general tendency to think of possibility in terms of the 'branching model' - that unactualised possibilities must branch off from actuality, at some point. | |
| From: Barbara Vetter (Potentiality [2015], 7.9) | |
| A reaction: [she cites P. Mackie 1998] It is hard to see how we could flatly deny some possibilities which had absolutely no connection with actuality, and were probably quite unimaginable for us. |
| 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. |
| 19008 | The modern revival of necessity and possibility treated them as special cases of quantification [Vetter] |
| Full Idea: Necessity and possibility had a revival with the development of modal logic, treating them as special cases of the existential and universal quantifiers, ranging over an infinity of possible worlds. | |
| From: Barbara Vetter (Potentiality [2015], 1.1) | |
| A reaction: The problem seems to be that possible worlds offer a very useful and interesting 'model' of modality, but say nothing at all about its nature. Any more than a weather map will show you what weather is. |
| 19029 | It is necessary that p means that nothing has the potentiality for not-p [Vetter] |
| Full Idea: Necessities mark the limits of the potentialities that objects have. More precisely, it is necessary that p just in case nothing has, or had, or will have a potentiality to be such that not-p. | |
| From: Barbara Vetter (Potentiality [2015], 6.2) | |
| A reaction: [See Vetter's other ideas for her potentiality account of modality] If we wish to build a naturalistic account of modality (and if you don't want that then your untethered metaphysics will drift away in logical space) then this is the way to go. |
| 19028 | Possibilities are potentialities of actual things, but abstracted from their location [Vetter] |
| Full Idea: When we speak of possibility, we speak of potentiality in abstraction from its possessor; a possibility is a potentiality somewhere or other in the world, no matter where. | |
| From: Barbara Vetter (Potentiality [2015], 6.1) | |
| A reaction: I note that, as so often, this is psychological abstraction, which is usually sneered at by modern philosophers (e.g. Geach), and yet is employed all the time. This is Vetter's key thesis, which I like. |
| 19010 | All possibility is anchored in the potentiality of individual objects [Vetter] |
| Full Idea: Potentiality is, metaphorically speaking, possibility anchored in individual objects; I claim that all possibility is thus anchored in some individual object(s) or other. | |
| From: Barbara Vetter (Potentiality [2015], 1.1) | |
| A reaction: This will be fine for specific physical possibilities, but may become tricky for possibilities that are increasingly abstract, or universal, or idealised. I agree with the general approach. Anchor modality in reality (which is physical!). |
| 19013 | Possibility is a generalised abstraction from the potentiality of its bearer [Vetter] |
| Full Idea: We should think of possibility as potentiality in abstraction from its bearer. So 'it is possible that p' is defined as 'something has an iterated potentiality for it to be the case that p'. | |
| From: Barbara Vetter (Potentiality [2015], 1.4) | |
| A reaction: If possibilities are abstractions from potentialities, I am inclined the treat potentialities as abstractions from dispositions, and dispositions (and properties) as abstractions from powers. Powers are not abstractions - they are the reality. |
| 19019 | Potentiality is the common genus of dispositions, abilities, and similar properties [Vetter] |
| Full Idea: Potentiality can now be recognised as the common genus of dispositions and such related properties as abilities. | |
| From: Barbara Vetter (Potentiality [2015], 4.1) | |
| A reaction: This is the reason why Vetter defends a metaphysics of modality based on potentialities, rather than on narrower concepts such as dispositions, powers or essences. She can evade the problems which those narrower concepts raise. |
| 19022 | Water has a potentiality to acquire a potentiality to break (by freezing) [Vetter] |
| Full Idea: Water has no potentiality to break. But water has a potentiality to be frozen and turn into ice, which does have a potentiality to break. So water has a potentiality to acquire a potentiality to break. | |
| From: Barbara Vetter (Potentiality [2015], 4.6) | |
| A reaction: Thus potentially has an 'iterated' character to it, and an appropriate modal logic for it will have to allow for those iterations. She suggests a version of System T modal logic. |
| 23705 | A potentiality may not be a disposition, but dispositions are strong potentialities [Vetter, by Friend/Kimpton-Nye] |
| Full Idea: Although not all potentialities are dispositions, Vetter claims that all dispositions are potentialities which are had to a sufficiently high degree. | |
| From: report of Barbara Vetter (Potentiality [2015]) by Friend/Kimpton-Nye - Dispositions and Powers 2.4.2 | |
| A reaction: This sounds plausible. A potentiality could be faint or negligible, but once it is a serious possibility it becomes a 'disposition'. ...I suppose. But if the meteor is probably going to hit my house, it doesn't mean it has a disposition to do so. |
| 19009 | Potentiality does the explaining in metaphysics; we don't explain it away or reduce it [Vetter] |
| Full Idea: This book is a plea for recognising potentiality as an explanans in the metaphysics of modality, rather than as something in need of explanation or reduction. | |
| From: Barbara Vetter (Potentiality [2015], 1.1) | |
| A reaction: Something has to do the explaining, and it is obviously much better to have some aspect of the real world do the job, rather than remote abstractions such as laws, possible worlds or Forms. Personally I like the potentiality of 'powers'. |
| 19027 | Potentiality logic is modal system T. Stronger systems collapse iterations, and necessitate potentials [Vetter] |
| Full Idea: The logic for potentiality corresponds to modal system T, the minimum for metaphysics. The S4 axiom ◊◊φ → ◊φ says iterated potentialities collapse, and the S5 ◊φ → □◊φ says potentialities can't be lost. | |
| From: Barbara Vetter (Potentiality [2015], 5.9) | |
| A reaction: [compressed] This seems persuasive. I nice example of modern analytic metaphysics, that you have to find a logic that suits your theory. N.Salmon defends system T for all of metaphysics, though most people favour S5. |
| 19025 | Potentialities may be too weak to count as 'dispositions' [Vetter] |
| Full Idea: Potentialities may get exercised despite having a degree that is too low for them to qualify as dispositions. | |
| From: Barbara Vetter (Potentiality [2015], 5.7.4) | |
| A reaction: The key reason why her book is called 'Potentialities', rather than 'Dispositions'. She still wants to offer a naturalistic picture which ties potentialities to individual objects, but I am wondering whether potentialities are too abstract for the job. |
| 19031 | There are potentialities 'to ...', but possibilities are 'that ....'. [Vetter] |
| Full Idea: Potentialities are 'potentialities to ....', while possibilities are 'possibilities that ....'. | |
| From: Barbara Vetter (Potentiality [2015], 6.4) | |
| A reaction: This feels a bit like a stipulation, rather than a precise description of normal usage. That said, it is quite a nice distinction. It sounds as if an event follows a potentiality, and a state of affairs follows a possibility. Active and passive? |
| 19011 | If worlds are sets of propositions, how do we know which propositions are genuinely possible? [Vetter] |
| Full Idea: If possible worlds are sets of propositions, we need some way to distinguish those sets of propositions that do from those that do not correspond to genuine possibilities. | |
| From: Barbara Vetter (Potentiality [2015], 1.2) | |
| A reaction: The idea of a 'genuine' possibility does not seem to play a role in the conceptual scheme of those who treat possibility entirely in terms of possible worlds. If possibility is primitive, or is a set of worlds, there can be no criterion for 'genuine'. |
| 19037 | Are there possible objects which nothing has ever had the potentiality to produce? [Vetter] |
| Full Idea: Is it not possible that there be objects with (natural) properties that no actual thing ever had the potentiality to have, to produce, or constitute? (Call such properties 'super-alien properties'). | |
| From: Barbara Vetter (Potentiality [2015], 7.5) | |
| A reaction: This is a problem for her potentiality account of possibility. Her solution is (roughly) to either deny the super-aliens, or have chains of iterated possibility which take this case back to actuality. That sounds OK to me. |
| 4421 | Philosophers have never asked why there is a will to truth in the first place [Nietzsche] |
| Full Idea: Both the earliest and most recent philosophers are all oblivious of how much the will to truth itself first requires justification: here there is a gap in every philosophy - how did this come about? | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§24) | |
| A reaction: This seems to me a meta-philosophical question which will lead off into (quite interesting) cultural studies and (trite) evolutionary theory. Truth isn't a value, it is the biological function of brains. |
| 23719 | Forgetfulness is a strong positive ability, not mental laziness [Nietzsche] |
| Full Idea: Forgetfulness is not just a vis inertiae, as superficial people believe, but is rather an active ability to suppress, positive in the strongest sense of the word. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§01) | |
| A reaction: It is unimpressive when people remember small slights and grievances for a long time - and even being owed small sums - so the ability to forget such things is admirable. But wilfully forgetting some things is obviously shameful. |
| 4420 | There is only 'perspective' seeing and knowing, and so the best objectivity is multiple points of view [Nietzsche] |
| Full Idea: There is only a perspective seeing, only a perspective "knowing", and the more different eyes we can use to observe one thing, the more complete will our "concept" of this thing, our "objectivity", be. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§12) | |
| A reaction: A very perceptive statement of the most plausible and sophisticated version of relativism. It is hard to see how we could distinguish multiple viewpoints from pure objectivity. |
| 19018 | Explanations by disposition are more stable and reliable than those be external circumstances [Vetter] |
| Full Idea: Patterns of behaviour may be explained by circumstances external to the individual, but dispositional explanations, based on the instrinsic make-up of individuals are typically more reliable and stable. | |
| From: Barbara Vetter (Potentiality [2015], 3.5) | |
| A reaction: [compressed] This is very nice support for the view I have been defending. She doesn't deal in essences, and prefers 'potentialities' (as broader) to 'dispositions'. The point is to explain events by the natures of the ingredients. |
| 19020 | Grounding is a kind of explanation, suited to metaphysics [Vetter] |
| Full Idea: Grounding is a kind of explanation - and specifically, the kind of metaphysical explanation that metaphysicians are after. | |
| From: Barbara Vetter (Potentiality [2015], 4.5) | |
| A reaction: Depending on how you interpret 'grounding', it is plausible that it is the sort of explanation that physicists and economists are after as well. If the aim is to understand the structure of everything, the target is to know what grounds what. |
| 4414 | Philosophers invented "free will" so that our virtues would be permanently interesting to the gods [Nietzsche] |
| Full Idea: The philosophers invented "free will" - absolute human spontaneity in good and evil - to furnish a right to the idea that the interest of the gods in man, in human virtue, could never be exhausted. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§07) | |
| A reaction: Wonderfully outrageous suggestion! If we had true metaphysical 'absolute' free will, we would be much more interesting, and have a much higher status in the cosmos. Nietzsche is probably right. |
| 4419 | People who think in words are orators rather than thinkers, and think about facts instead of thinking facts [Nietzsche] |
| Full Idea: Whoever thinks in words thinks as an orator and not as a thinker (it shows that he does not think facts, but only in relation to facts). | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§08) | |
| A reaction: Good. It is certainly not true that we have to think in words, or else animals wouldn't think. Good thinking should focus on reality, and be too fast for words to keep up. |
| 4411 | It is a delusion to separate the man from the deed, like the flash from the lightning [Nietzsche] |
| Full Idea: Just as the popular mind separates the lightning from its flash and takes the latter for a 'action', so they separate strength from expressions of strength, but there is no such substratum; the deed is everything. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§13) | |
| A reaction: Of course, there is no reason why an analysis should not separate the doer and the deed (to explain, for example, a well-meaning fool), but it is a blunder to think of a human action as a merely physical event. |
| 3793 | We must question the very value of moral values [Nietzsche] |
| Full Idea: We need a critique of moral values; the value of these values themselves must just be called in question. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], Pre f§3) | |
| A reaction: But we must start somewhere with values, to avoid an infinite regress. |
| 4408 | The concept of 'good' was created by aristocrats to describe their own actions [Nietzsche] |
| Full Idea: The judgement 'good' did not first originate with those to whom goodness was shown! Rather it was the 'good' themselves, that is to say the noble, powerful, high-stationed and high-minded who established themselves and their action as good. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§02) | |
| A reaction: This may be right, but not very profound. Virtually all concepts are created by the most educated classes. The first recipient of charity may not have had the concept, but they would have been gobsmacked by the novelty. |
| 23716 | A strong rounded person soon forgets enemies, misfortunes, and even misdeeds [Nietzsche] |
| Full Idea: To be unable to take his enemies, his misfortunes and even his misdeeds seriously for long - that is the sign of strong, rounded natures with a superabundance of power. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§10) | |
| A reaction: An aspect of the 'higher man' that I don't recall being mentioned elsewhere. I basically approve of this, if it means not holding grudges, and living for the future rather than for the past. |
| 20129 | All animals strive for the ideal conditions to express their power, and hate any hindrances [Nietzsche] |
| Full Idea: Every animal instinctively strives for an optimum of favourable conditions under which it can expend all its strength and achieve its maximal feeling of power; every animal abhors ...every hindrance that obstructs this path to the optimum. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], III.§07) | |
| A reaction: This became the lynchpin of Nietzsche's account of the source of values. It is a highly naturalistic view, fitting it into evolutionary theory (thought running deeper than that), so I have a lot of sympathy with the view. |
| 4409 | Only the decline of aristocratic morality led to concerns about "egoism" [Nietzsche] |
| Full Idea: It was only when aristocratic value judgements declined that the whole antithesis of "egoistic" and "unegoistic" obtruded itself more and more on the human conscience. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§02) | |
| A reaction: But Aristotle, who is no aristocrat, has a balanced and sensible view of 'egoism', where it isn't the patronising arrogance that Nietzsche seems to like, but a proper concern with one's own character. |
| 3259 | Nietzsche rejects impersonal morality, and asserts the idea of living well [Nietzsche, by Nagel] |
| Full Idea: Nietzsche's rejection of impersonal morality is an assertion of the dominance of the ideal of living well. | |
| From: report of Friedrich Nietzsche (On the Genealogy of Morals [1887], I) by Thomas Nagel - The View from Nowhere X.2 |
| 4416 | Basic justice is the negotiation of agreement among equals, and the imposition of agreement [Nietzsche] |
| Full Idea: Justice on the elementary level is good will among parties of approximately equal power to come to terms with one another, and to compel parties of lesser power to reach a settlement among themselves. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§08) | |
| A reaction: This pinpoints a key problem with the social contract as a moral theory - that it requires equals, and recognises only terror of superiors, and indifference to useless inferiors who have nothing to offer (paraplegics and animals). |
| 4418 | A masterful and violent person need have nothing to do with contracts [Nietzsche] |
| Full Idea: He who can command, he who is "master", he who is violent in act and bearing - what has he to do with contracts! | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§17) | |
| A reaction: The persistent problem with social contract theory is that those much stronger or much weaker seem to have no interest in morality at all, and yet they can all have standards of behaviour. |
| 4407 | Plato, Spinoza and Kant are very different, but united in their low estimation of pity [Nietzsche] |
| Full Idea: Plato, Spinoza, La Rochefoucauld, and Kant are four spirits very different from one another, but united in one thing: their low estimation of pity. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], Pref §5) | |
| A reaction: Plato is no surprise, as virtually no Greeks value pity. Spinoza and Kant are interesting. Presumably Kant's 'contractualism' places respect far above pity, and is theoretical neglect of animals would fit. Remember Nietzsche embraced a horse in Turin. |
| 4415 | Guilt and obligation originated in the relationship of buying and selling, credit and debt [Nietzsche] |
| Full Idea: The feeling of guilt, of personal obligation, had its origin in the oldest and most primitive personal relationship, that between buyer and seller, between creditor and debtor. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§08) | |
| A reaction: In other words, lofty Kantian ideals started life in the grubby world of the Hobbesian social contract, and self-seeking has been disguised by idealism. Too harsh on Kant, who explains why contracts have force, not just convenience. |
| 23718 | If we say birds of prey could become lambs, that makes them responsible for being birds of prey [Nietzsche] |
| Full Idea: Scientists …do not defend any belief more strongly than that the strong are free to be weak, and the birds of prey are free to be lambs: - in this way, they gain the right to make the birds of prey responsible for being birds of prey. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§13) | |
| A reaction: This is a flat rejection of the Sartrean idea that we can what sort of person we want to be. He cares about birds of prey, but also lambs can't become eagles. I would say that adolescents have a reasonable degree of choice about what they will become. |
| 23717 | Modern nihilism is now feeling tired of mankind [Nietzsche] |
| Full Idea: The sight of man now makes us tired - what is nihilism today if it is not that? …We are tired of man… | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§12) | |
| A reaction: That is close to Hume's nihilist, who would destroy the world to protect his own finger from a scratch. The actor George Sanders committed suicide because he was bored. Don't ever think that Nietzsche was a nihilist, just because he mentions it a lot! |
| 23721 | Old tribes always felt an obligation to the earlier generations, and the founders [Nietzsche] |
| Full Idea: Within the original tribal association the living generation always acknowledged a legal obligation towards the earlier generation, and in particular towards the earliest. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§19) | |
| A reaction: This is still a factor in modern politics, though the people remember are either military heroes or the great figures of a particular political movement. We remember the big artists and personalities, but don't feel obligated to them. |
| 20142 | The state begins with brutal conquest of a disorganised people, not with a 'contract' [Nietzsche] |
| Full Idea: Some pack of blond beasts of prey, on a war footing, unscrupulously lays its dreadful paws on a populace which is shapeless. In this way the 'state' began on earth. I think I have dispensed with the fantasy which has it begin with a 'contract'. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§17) | |
| A reaction: [compressed] It is certainly likely that a tribe which got itself well organised and focused on some end would achieve total dominance over other tribes that just focus on food. |
| 23720 | Punishment makes people harder, more alienated, and hostile [Nietzsche] |
| Full Idea: On the whole, punishment makes men harder and colder, it concentrates, it sharpens the feeling of alienation; it strengthens the power to resist. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], II.§14) | |
| A reaction: If the school system involves routine harsh punishments, that means that the whole population ends up in that state. I would have thought that this was an obvious truth about punishment, but no one seems to want to face up to it. |
| 222 | Only a great person can understand the essence of things, and an even greater person can teach it [Plato] |
| Full Idea: Only a man of very great natural gifts will be able to understand that everything has a class and absolute essence, and an even more wonderful man can teach this. | |
| From: Plato (Parmenides [c.364 BCE], 135a) |
| 225 | The unlimited has no shape and is endless [Plato] |
| Full Idea: The unlimited partakes neither of the round nor of the straight, because it has no ends nor edges. | |
| From: Plato (Parmenides [c.364 BCE], 137e) |
| 233 | Some things do not partake of the One [Plato] |
| Full Idea: The others cannot partake of the one in any way; they can neither partake of it nor of the whole. | |
| From: Plato (Parmenides [c.364 BCE], 159d) | |
| A reaction: Compare Idea 231 |
| 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. |
| 19039 | The view that laws are grounded in substance plus external necessity doesn't suit dispositionalism [Vetter] |
| Full Idea: The Armstrong/Tooley/Dretske view, which takes laws to be substantial but grounded in a relation of nomic necessitation external to the properties themselves, is not an attractive option for the dispositionalist. | |
| From: Barbara Vetter (Potentiality [2015], 7.8) | |
| A reaction: The point is that the dispositionalist sees laws as grounded in the properties. I prefer her other option, of dispositionalism plus a 'shallow' view of laws (which she attributes to Mumford). The laws are as Lewis says, but powers explain them. |
| 19038 | Dispositional essentialism allows laws to be different, but only if the supporting properties differ [Vetter] |
| Full Idea: Even on the dispositional essentialist view the world might have been governed by different laws, if those laws involved different properties. What is excluded is the possibility of different laws involving the same properties as our actual laws. | |
| From: Barbara Vetter (Potentiality [2015], 7.8) | |
| A reaction: Important. Critics of dispositional essentialism accuse it of promoting the idea that the laws of nature are necessary, a claim for which we obviously have no evidence. I prefer to say they are necessary given that 'stuff', rather than those properties. |
| 19026 | If time is symmetrical between past and future, why do they look so different? [Vetter] |
| Full Idea: Any defender of the symmetry of time will have to provide some explanation of the obstinate appearance that the future is very different from the past. | |
| From: Barbara Vetter (Potentiality [2015], 5.8) | |
| A reaction: Presumably you have to say that it is all there, but only one end of the time spectrum is revealed to us, namely the past. But how do we get this uniquely lopsided view? Being an ominiscient god is more obvious than being a lopsided human. |
| 19041 | Presentists explain cross-temporal relations using surrogate descriptions [Vetter] |
| Full Idea: Presentists usually deal with the lack of cross-temporal relations by the construction of a surrogate, by way of paraphrasing the objectionable relation ascriptions. 'I admire Socrates' becomes 'I admire the Socrates properties'. | |
| From: Barbara Vetter (Potentiality [2015], 7.9) | |
| A reaction: [compressed. The cites Markosian 2004:63] Why can't I just say 'I admire Socrates, who no longer exists'? The present includes tensed facts, and memories and evidence-based theories. Admiring is not a direct relation between objects. |
| 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) |
| 4410 | The truly great haters in world history have always been priests [Nietzsche] |
| Full Idea: The truly great haters in world history have always been priests. | |
| From: Friedrich Nietzsche (On the Genealogy of Morals [1887], I.§07) | |
| A reaction: Wicked, but it has a lot of truth. Priests have a lot to defend, and a lot of reasons for feeling threatened. |
