23295 | Truth cannot be reduced to anything simpler [Davidson] |
Full Idea: We cannot hope to underpin the concept of truth with something more transparent or easier to grasp. | |
From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21) | |
A reaction: I suppose precise accounts of correspondence or coherence are offered as replacements for truth, but neither of those ever seem to be possible. I agree with accepting truth as a primitive. |
23298 | Neither Aristotle nor Tarski introduce the facts needed for a correspondence theory [Davidson] |
Full Idea: Neither Aristotle's formula nor Tarski's truth definitions are sympathetic to the correspondence theory, because they don't introduce entities like facts or states of affairs for sentences to correspond. | |
From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.25) | |
A reaction: This seems convincing, although it is often claimed that both theories offer a sort of correspondence. |
23297 | The language to define truth needs a finite vocabulary, to make the definition finite [Davidson] |
Full Idea: If the definition of the truth predicate is to be finite (Tarski insisted on this), the definition must take advantage of the fact that sentences, though potentially infinite in number, are constructed from a finite vocabulary. | |
From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.23) | |
A reaction: Not sure whether this is in the object language or the meta-language, though I guess the former. |
23296 | We can elucidate indefinable truth, but showing its relation to other concepts [Davidson] |
Full Idea: We can still say revealing things about truth, by relating it to other concepts like belief, desire, cause and action. | |
From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.21) | |
A reaction: The trickiest concept to link it to is meaning. I think Davidson's view points to the Axiomatic account of truth, which flourished soon after Davidson wrote this. We can give rules for the correct use of 'true'. |
18431 | Internal relations combine some tropes into a nucleus, which bears the non-essential tropes [Simons, by Edwards] |
Full Idea: Simons's 'nuclear' option blends features of the substratum and bundle theories. First we have tropes collected by virtue of their internal relations, forming the essential kernel or nucleus. This nucleus then bears the non-essential tropes. | |
From: report of Peter Simons (Particulars in Particular Clothing [1994], p.567) by Douglas Edwards - Properties 3.5 | |
A reaction: [compression of Edwards's summary] This strikes me as being a remarkably good theory. I am not sure of the ontological status of properties, such that they can (unaided) combine to make part of an object. What binds the non-essentials? |
23294 | It is common to doubt truth when discussing it, but totally accept it when discussing knowledge [Davidson] |
Full Idea: You are following Plato's lead if you worry about the concept of truth when it is the focus of your attention, but you pretend you understand it when trying to cope with knowledge (or belief, memory, perception etc.). | |
From: Donald Davidson (The Folly of Trying to Define Truth [1999], p.20) | |
A reaction: Nice to find someone pointing out this absurdity. He says Hume does the same with doubts about the external world, which he ignores when discussing other minds. Belief is holding true; only truths are actually remembered…. |
17488 | Empiricist theories are sets of laws, which give explanations and reductions [Glennan] |
Full Idea: In the empiricist tradition theories were understood to be deductive closures of sets of laws, explanations were understood as arguments from covering laws, and reduction was understood as a deductive relationship between laws of different theories. | |
From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
A reaction: A lovely crisp summary of the whole tradition of philosophy of science from Comte through to Hempel. Mechanism and essentialism are the new players in the game. |
17493 | Modern mechanism need parts with spatial, temporal and function facts, and diagrams [Glennan] |
Full Idea: Modern champions of mechanisms say models should identify both the parts and their spatial, temporal and functional organisation, ...and the practical importance of diagrams in addition to or in place of linguistic representations of mechanisms. | |
From: Stuart Glennan (Mechanisms [2008], 'Discover') | |
A reaction: Apparently chemists obtain much more refined models by using mathematics than they did by diagrams or 3D models (let alone verbal descriptions). For that reason, I'm thinking that 'model' might be a better term than 'mechanism'. |
17487 | Mechanistic philosophy of science is an alternative to the empiricist law-based tradition [Glennan] |
Full Idea: To a significant degree, a mechanistic philosophy of science can be seen as an alternative to an earlier logical empiricist tradition in philosophy of science that gave pride of place to laws of nature. | |
From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
A reaction: Lovely! Someone who actually spells out what's going on here. Most philosophers are far too coy about explaining what their real game is. Mechanism is fine in chemistry and biology. How about in 'mathematical' physics, or sociology? |
17489 | Mechanisms are either systems of parts or sequences of activities [Glennan] |
Full Idea: There are two sorts of mechanisms: systems consist of collections of parts that interact to produce some behaviour, and processes are sequences of activities which produce some outcome. | |
From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
A reaction: [compressed] The second one is important because it is more generic, and under that account all kinds the features of the world that need to be explained can be subsumed. E.g. hyperinflation in an economy is a 'mechanism'. |
17490 | 17th century mechanists explained everything by the kinetic physical fundamentals [Glennan] |
Full Idea: 17th century mechanists said that interactions governed by chemical, electrical or gravitational forces would have to be explicable in terms of the operation of some atomistic (or corpuscular) kinetic mechanism. | |
From: Stuart Glennan (Mechanisms [2008], 'Intro') | |
A reaction: Glennan says science has rejected this, so modern mechanists do not reduce mechanisms to anything in particular. |
17491 | Unlike the lawlike approach, mechanistic explanation can allow for exceptions [Glennan] |
Full Idea: One of the advantages of the move from nomological to mechanistic modes of explanation is that the latter allows for explanations involving exception-ridden generalizations. | |
From: Stuart Glennan (Mechanisms [2008], 'regular') | |
A reaction: The lawlike approach has endless problems with 'ceteris paribus' ('all things being equal') laws, where specifying all the other 'things' seems a bit tricky. |
17494 | Since causal events are related by mechanisms, causation can be analysed in that way [Glennan] |
Full Idea: Causation can be analyzed in terms of mechanisms because (except for fundamental causal interactions) causally related events will be connected by intervening mechanisms. | |
From: Stuart Glennan (Mechanisms [2008], 'causation') | |
A reaction: This won't give us the metaphysics of causation (which concerns the fundamentals), but this strikes me as a very coherent and interesting proposal. He mentions electron interaction as non-mechanistic causation. |
