19090 | If we can't check our language against experience, philosophy is just comparing beliefs and words [Rorty] |
Full Idea: If we cannot check our language against non-linguistic awareness, then philosophy can never be more than a discussion of the utility and compatibility of beliefs - and, more particularly, of the various vocabularies in which those beliefs are formulated. | |
From: Richard Rorty (Brandom on Social Practices and Representations [1998], iii.127), quoted by Danielle Macbeth - Pragmatism and Objective Truth p.178 | |
A reaction: I'm amazed at how many people I encounter in philosophy circles (compared with none at all outside those circles) who seem to think that we cannot check our language against our non-linguistic awareness. Rorty is their guru. Weird. |
2557 | Analytical philosophy seems to have little interest in how to tell a good analysis from a bad one [Rorty] |
Full Idea: There is nowadays little attempt to bring "analytic philosophy" to self-consciousness by explaining how to tell a successful from an unsuccessful analysis. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 4.1) |
2556 | Rational certainty may be victory in argument rather than knowledge of facts [Rorty] |
Full Idea: We can think of "rational certainty" as a matter of victory in argument rather than relation to an object known. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 3.4) |
4726 | Rorty seems to view truth as simply being able to hold one's view against all comers [Rorty, by O'Grady] |
Full Idea: Rorty seems to view truth as simply being able to hold one's view against all comers. | |
From: report of Richard Rorty (Philosophy and the Mirror of Nature [1980]) by Paul O'Grady - Relativism Ch.4 | |
A reaction: This may be a caricature of Rorty, but he certainly seems to be in the business of denying truth as much as possible. This strikes me as the essence of pragmatism, and as a kind of philosophical nihilism. |
2549 | For James truth is "what it is better for us to believe" rather than a correct picture of reality [Rorty] |
Full Idea: Truth is, in James' phrase, "what it is better for us to believe", rather than "the accurate representation of reality". | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], Intro) |
21554 | Sets always exceed terms, so all the sets must exceed all the sets [Lackey] |
Full Idea: Cantor proved that the number of sets in a collection of terms is larger than the number of terms. Hence Cantor's Paradox says the number of sets in the collection of all sets must be larger than the number of sets in the collection of all sets. | |
From: Douglas Lackey (Intros to Russell's 'Essays in Analysis' [1973], p.127) | |
A reaction: The sets must count as terms in the next iteration, but that is a normal application of the Power Set axiom. |
21553 | It seems that the ordinal number of all the ordinals must be bigger than itself [Lackey] |
Full Idea: The ordinal series is well-ordered and thus has an ordinal number, and a series of ordinals to a given ordinal exceeds that ordinal by 1. So the series of all ordinals has an ordinal number that exceeds its own ordinal number by 1. | |
From: Douglas Lackey (Intros to Russell's 'Essays in Analysis' [1973], p.127) | |
A reaction: Formulated by Burali-Forti in 1897. |
14193 | 'Substance theorists' take modal properties as primitive, without structure, just falling under a sortal [Paul,LA] |
Full Idea: Some deep essentialists resist the need to explain the structure under de re modal properties, taking them as primitive. One version (which we can call 'substance theory') takes them to fall under a sortal concept, with no further explanation. | |
From: L.A. Paul (In Defense of Essentialism [2006], §1) | |
A reaction: A very helpful identification of what Wiggins stands for, and why I disagree with him. The whole point of essences is to provide a notion that fits in with sciences, which means they must have an explanatory role, which needs structures. |
14195 | If an object's sort determines its properties, we need to ask what determines its sort [Paul,LA] |
Full Idea: If the substance essentialist holds that the sort an object belongs to determines its de re modal properties (rather than the other way round), then he needs to give an (ontological, not conceptual) explanation of what determines an object's sort. | |
From: L.A. Paul (In Defense of Essentialism [2006], §1) | |
A reaction: See Idea 14193 for 'substance essentialism'. I find it quite incredible that anyone could think that a thing's sort could determine its properties, rather than the other way round. Even if sortals are conventional, they are not arbitrary. |
14196 | Substance essentialism says an object is multiple, as falling under various different sortals [Paul,LA] |
Full Idea: The explanation of material constitution given by substance essentialism is that there are multiple objects. A person is essentially human-shaped (falling under the human sort), while their hunk of tissue is accidentally human-shaped (as tissue). | |
From: L.A. Paul (In Defense of Essentialism [2006], §1) | |
A reaction: At this point sortal essentialism begins to look crazy. Persons are dubious examples (with sneaky dualism involved). A bronze statue is essentially harder to dent than a clay one, because of its bronze. If you remake it of clay, it isn't the same statue. |
14198 | Absolutely unrestricted qualitative composition would allow things with incompatible properties [Paul,LA] |
Full Idea: Absolutely unrestricted qualitative composition would imply that objects with incompatible properties and objects such as winged pigs or golden mountains were actual. | |
From: L.A. Paul (In Defense of Essentialism [2006], §5) | |
A reaction: Note that this is 'qualitative' composition, and not composition of parts. The objection seems to rule out unrestricted qualitative composition, since you could hardly combine squareness with roundness. |
14190 | Deep essentialist objects have intrinsic properties that fix their nature; the shallow version makes it contextual [Paul,LA] |
Full Idea: Essentialism says that objects have their properties essentially. 'Deep' essentialists take the (nontrivial) essential properties of an object to determine its nature. 'Shallow' essentialists substitute context-dependent truths for the independent ones. | |
From: L.A. Paul (In Defense of Essentialism [2006], Intro) | |
A reaction: If the deep essence determines a things nature, we should not need to say 'nontrivial'. This is my bete noire, the confusion of essential properties with necessary ones, where necessary properties (or predicates, at least) can indeed be trivial. |
14191 | Deep essentialists say essences constrain how things could change; modal profiles fix natures [Paul,LA] |
Full Idea: The deep essentialist holds that most objects have essential properties such that there are many ways they could not be, or many changes through which they could not persist. Objects' modal profiles characterize their natures. | |
From: L.A. Paul (In Defense of Essentialism [2006], Intro) | |
A reaction: This is the view I like, especially the last bit. If your modal profile doesn't determine your nature, then what does? Think of how you sum up a person at a funeral. Your modal profile is determined by dispositions and powers. |
14192 | Essentialism must deal with charges of arbitrariness, and failure to reduce de re modality [Paul,LA] |
Full Idea: Two objections to deep essentialism are that it falters when faced with a skeptical objection concerning arbitrariness, and the need for a reductive account of de re modality. | |
From: L.A. Paul (In Defense of Essentialism [2006], Intro) | |
A reaction: An immediate response to the second objection might be to say that modal facts about things are not reducible. The charge of arbitrariness (i.e. total arbitrariness, not just a bit of uncertainty) is the main thing a theory of essences must deal with. |
14197 | An object's modal properties don't determine its possibilities [Paul,LA] |
Full Idea: I reject the view that an object's de re modal properties determine its relations to possibilia. | |
From: L.A. Paul (In Defense of Essentialism [2006], §3) | |
A reaction: You'll have to read Paul to see why, but I flat disagree with her on this. The whole point of accepting such properties is to determine the modal profile of the thing, and hence see how it can fit into and behave in the world. |
14189 | 'Modal realists' believe in many concrete worlds, 'actualists' in just this world, 'ersatzists' in abstract other worlds [Paul,LA] |
Full Idea: A 'modal realist' believes that there are many concrete worlds, while the 'actualist' believes in only one concrete world, the actual world. The 'ersatzist' is an actualist who takes nonactual possible worlds and their contents to be abstracta. | |
From: L.A. Paul (In Defense of Essentialism [2006], Intro) | |
A reaction: My view is something like that modal realism is wrong, and actualism is right, and possible worlds (if they really are that useful) are convenient abstract fictions, constructed (if we have any sense) out of the real possibilities in the actual world. |
2548 | If knowledge is merely justified belief, justification is social [Rorty] |
Full Idea: If we have a Deweyan conception of knowledge, as what we are justified in believing, we will see "justification" as a social phenomenon. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], Intro) | |
A reaction: I find this observation highly illuminating (though I probably need to study Dewey to understand it). There just is no absolute about whether someone is justified. How justified do you want to be? |
6599 | Knowing has no definable essence, but is a social right, found in the context of conversations [Rorty] |
Full Idea: If we see knowing not as having an essence, described by scientists or philosophers, but rather as a right, by current standards, to believe, then we see conversation as the ultimate context within which knowledge is to be understood. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], Ch.5), quoted by Robert Fogelin - Walking the Tightrope of Reason Ch.5 | |
A reaction: This teeters towards ridiculous relativism (e.g. what if the conversation is among a group of fools? - Ah, there are no fools! Politically incorrect!). However, knowledge can be social, provided we are healthily elitist. Scientists know more than us. |
2566 | You can't debate about whether to have higher standards for the application of words [Rorty] |
Full Idea: The decision about whether to have higher than usual standards for the application of words like "true" or "good" or "red" is, as far as I can see, not a debatable issue. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.6) |
2553 | The mind is a property, or it is baffling [Rorty] |
Full Idea: All that is needed for the mind-body problem to be unintelligible is for us to be nominalist, to refuse firmly to hypostasize individual properties. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 1.3) | |
A reaction: Edelman says the mind is a process rather than a property. It might vanish if the clockspeed was turned right down? Nominalism here sounds like behaviourism or instrumentalism. Would Dennett plead guilty? |
2550 | Pain lacks intentionality; beliefs lack qualia [Rorty] |
Full Idea: We can't define the mental as intentional because pains aren't about anything, and we can't define it as phenomenal because beliefs don't feel like anything. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 1.2) | |
A reaction: Nice, but simplistic? There is usually an intentional object for a pain, and the concepts which we use to build beliefs contain the residue of remembered qualia. It seems unlikely that any mind could have one without the other (even a computer). |
2554 | Is intentionality a special sort of function? [Rorty] |
Full Idea: Following Wittgenstein, we shall treat the intentional as merely a subspecies of the functional. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 1.3) | |
A reaction: Intriguing but obscure. Sounds wrong to me. The intentional refers to the content of thoughts, but function concerns their role. They have roles because they have content, so they can't be the same. |
2565 | Nature has no preferred way of being represented [Rorty] |
Full Idea: Nature has no preferred way of being represented. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.5) | |
A reaction: Tree rings accidentally represent the passing of the years. If God went back and started again would she or he opt for a 'preferred way'? |
2560 | Can meanings remain the same when beliefs change? [Rorty] |
Full Idea: For cooler heads there must be some middle view between "meanings remain and beliefs change" and "meanings change whenever beliefs do". | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.2) | |
A reaction: The second one seems blatanty false. How could we otherwise explain a change in belief? But obviously some changes in belief (e.g. about electrons) produce a change in meaning. |
2562 | A theory of reference seems needed to pick out objects without ghostly inner states [Rorty] |
Full Idea: The need to pick out objects without the help of definitions, essences, and meanings of terms produced, philosophers thought, a need for a "theory of reference". | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.3) | |
A reaction: Frege's was very perceptive in noting that meaning and reference are not the same. Whether we need a 'theory' of reference is unclear. It is worth describing how it occurs. |
2559 | Davidson's theory of meaning focuses not on terms, but on relations between sentences [Rorty] |
Full Idea: A theory of meaning, for Davidson, is not an assemblage of "analyses" of the meanings of individual terms, but rather an understanding of the inferential relations between sentences. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 6.1) | |
A reaction: Put that way, the influence of Frege on Davidson is obvious. Purely algebraic expressions can have inferential relations, using variables and formal 'sentences'. |
2558 | Since Hegel we have tended to see a human as merely animal if it is outside a society [Rorty] |
Full Idea: Only since Hegel have philosophers begun toying with the idea that the individual apart from his society is just one more animal. | |
From: Richard Rorty (Philosophy and the Mirror of Nature [1980], 4.3) |
