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) |
8964 | Entities can be multiplied either by excessive categories, or excessive entities within a category [Hoffman/Rosenkrantz] |
Full Idea: There are two ways that entities can be multiplied unnecessarily: by multiplying the number of explanatory categories, and by multiplying the number of entities within a category. | |
From: J Hoffman/G Rosenkrantz (Platonistic Theories of Universals [2003], 4) | |
A reaction: An important distinction. The orthodox view is that it is the excess of categories that is to be avoided (e.g. by nominalists). Possible worlds in metaphysics, and multiple worlds in physics, claim not to violate the first case. |
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) |
8962 | 'There are shapes which are never exemplified' is the toughest example for nominalists [Hoffman/Rosenkrantz] |
Full Idea: The example which presents the most serious challenge to nominalism is 'there are shapes which are never exemplified'. | |
From: J Hoffman/G Rosenkrantz (Platonistic Theories of Universals [2003], 3) | |
A reaction: To 'exemplify' a shape must it be a physical object, or a drawing of such an object, or a description? If none of those have ever existed, I'm not sure what 'are' is supposed to mean. They seem to be possibilia (with all the associated problems). |
8961 | Nominalists are motivated by Ockham's Razor and a distrust of unobservables [Hoffman/Rosenkrantz] |
Full Idea: The two main motivations for nominalism are an admirable commitment to Ockham's Razor, and a queasiness about postulating entities that are unobservable or non-empirical, existing in a non-physical realm. | |
From: J Hoffman/G Rosenkrantz (Platonistic Theories of Universals [2003], 3) | |
A reaction: It doesn't follow that because the entities are unobservable that they are non-physical. Consider the 'interior' of an electron. Neverless I share a love of Ockham's Razor and a deep caution about unobservables. |
13128 | 'Ultimate sortals' cannot explain ontological categories [Westerhoff on Wiggins] |
Full Idea: 'Ultimate sortals' are said to be non-subordinated, disjoint from one another, and uniquely paired with each object. Because of this, the ultimate sortal cannot be a satisfactory explication of the notion of an ontological category. | |
From: comment on David Wiggins (Identity and Spatio-Temporal Continuity [1971], p.75) by Jan Westerhoff - Ontological Categories §26 | |
A reaction: My strong intuitions are that Wiggins is plain wrong, and Westerhoff gives the most promising reasons for my intuition. The simplest point is that objects can obviously belong to more than one category. |
8963 | Four theories of possible worlds: conceptualist, combinatorial, abstract, or concrete [Hoffman/Rosenkrantz] |
Full Idea: There are four models of the ontological status of possible worlds: conceptualist (mental constructions), combinatorial (all combinations of the actual world), abstract worlds (conjunction of propositions), and concrete worlds (collections of concreta). | |
From: J Hoffman/G Rosenkrantz (Platonistic Theories of Universals [2003], 4) | |
A reaction: [the proponents cited are, in order, Rescher, Cresswell, Plantinga and Lewis] They dismiss Rescher and Cresswell, both of whom seem to me more plausible than Plantinga or Lewis. 'Possible' can't figure in the definition. Possible to us, or in reality? |
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) |
