6782 | Realism is the only philosophy of science that doesn't make the success of science a miracle [Putnam] |
Full Idea: Realism….is the only philosophy science which does not make the success of science a miracle. | |
From: Hilary Putnam (works [1980]), quoted by Alexander Bird - Philosophy of Science Ch.4 | |
A reaction: This was from his earlier work; he became more pragmatist and anti-realist later. Personally I approve of the remark. The philosophy of science must certainly offer an explanation for its success. Truth seems the obvious explanation. |
10825 | The notion of truth is to help us make use of the utterances of others [Field,H] |
Full Idea: I suspect that the original purpose of the notion of truth was to aid us in utilizing the utterances of others in drawing conclusions about the world,...so we must attend to its social role, and that being in a position to assert something is what counts. | |
From: Hartry Field (Tarski's Theory of Truth [1972], §5) | |
A reaction: [Last bit compressed] This sounds excellent. Deflationary and redundancy views are based on a highly individualistic view of utterances and truth, but we need to be much more contextual and pragmatic if we are to get the right story. |
10820 | In the early 1930s many philosophers thought truth was not scientific [Field,H] |
Full Idea: In the early 1930s many philosophers believed that the notion of truth could not be incorporated into a scientific conception of the world. | |
From: Hartry Field (Tarski's Theory of Truth [1972], §3) | |
A reaction: This leads on to an account of why Tarski's formal version was so important, and Field emphasises Tarski's physicalist metaphysic. |
13499 | Tarski reduced truth to reference or denotation [Field,H, by Hart,WD] |
Full Idea: Tarski can be viewed as having reduced truth to reference or denotation. | |
From: report of Hartry Field (Tarski's Theory of Truth [1972]) by William D. Hart - The Evolution of Logic 4 |
10818 | Tarski really explained truth in terms of denoting, predicating and satisfied functions [Field,H] |
Full Idea: A proper account of Tarski's truth definition explains truth in terms of three other semantic notions: what it is for a name to denote something, and for a predicate to apply to something, and for a function symbol to be fulfilled by a pair of things. | |
From: Hartry Field (Tarski's Theory of Truth [1972]) | |
A reaction: This is Field's 'T1' version, which is meant to spell out what was really going on in Tarski's account. |
10817 | Tarski just reduced truth to some other undefined semantic notions [Field,H] |
Full Idea: It is normally claimed that Tarski defined truth using no undefined semantic terms, but I argue that he reduced the notion of truth to certain other semantic notions, but did not in any way explicate these other notions. | |
From: Hartry Field (Tarski's Theory of Truth [1972], §0) |
15105 | F(x) walked into a bar. The barman said.. [Sommers,W] |
Full Idea: F(x) walked into a bar. The barman said, 'Sorry, we don't cater for functions'. | |
From: Will Sommers (talk [2019]) |
10819 | Tarski gives us the account of truth needed to build a group of true sentences in a model [Field,H] |
Full Idea: Model theory must choose the denotations of the primitives so that all of a group of sentences come out true, so we need a theory of how the truth value of a sentence depends on the denotation of its primitive nonlogical parts, which Tarski gives us. | |
From: Hartry Field (Tarski's Theory of Truth [1972], §1) |
10827 | Model theory is unusual in restricting the range of the quantifiers [Field,H] |
Full Idea: In model theory we are interested in allowing a slightly unusual semantics for quantifiers: we are willing to allow that the quantifier not range over everything. | |
From: Hartry Field (Tarski's Theory of Truth [1972], n 5) |
12408 | Sartre to Waitress: Coffee with no cream, please... [Sommers,W] |
Full Idea: Sartre to Waitress: Coffee with no cream, please. Waitress: Sorry, we're out of cream; would no milk do? | |
From: Will Sommers (talk [2019]) |
22181 | Putnam says anti-realism is a bad explanation of accurate predictions [Putnam, by Okasha] |
Full Idea: Putnam's 'no miracle' argument says that being an anti-realist is akin to believing in miracles (because of the accurate predictons). …It is a plausibility argument - an inference to the best explanation. | |
From: report of Hilary Putnam (works [1980]) by Samir Okasha - Philosophy of Science: Very Short Intro (2nd ed) 4 | |
A reaction: [not sure of ref] Putnam later backs off from this argument, but my personal realism rests on best explanation. Does anyone want to prefer an inferior explanation? The objection is that successful theories can turn out to be false. Phlogiston, ether. |
12397 | Said Plato: 'The things that we feel... [Sommers,W] |
Full Idea: Said Plato: 'The things that we feel/ Are not ontologically real,/ But just the excrescence/ Of numinous essence/ Our senses can never reveal.' [Basil Ransome-Davis] | |

20963 | A philosopher and his wife are out for a drive... [Sommers,W] |
Full Idea: A philosopher and his wife are out for a drive in the country. 'Oh look!' she says, 'Those sheep have been shorn.' 'Yes', says the philosopher, 'on this side'. | |
From: Will Sommers (talk [2019]) |
12402 | ..But if he's a student of Berkeley... [Sommers,W] |
Full Idea: (continued from 12401) ..But if he's a student of Berkeley,/ One thing will emerge, rather starkly,/ That he ought to believe/ What his senses perceive,/ No matter how dimly or darkly. [Leslie Johnson] | |
From: Will Sommers (talk [2019]) |
12409 | The philosopher Berkeley once said.. [Sommers,W] |
Full Idea: The philosopher Berkeley once said/ In the dark to a maid in his bed:/ 'No perception, my dear,/ Means I'm not really here,/ But only a thought in your head.' [P.W.R. Foot] | |
From: Will Sommers (talk [2019]) |
12403 | There once was a man who said: 'God... [Sommers,W] |
Full Idea: There once was a man who said: 'God/ Must think it exceedingly odd/ If he finds that this tree/ Continues to be,/ When there's no-one about in the Quad.' [Ronald Knox] (reply in 12404) | |
From: Will Sommers (talk [2019]) |
12404 | Dear Sir, Your astonishment's odd.... [Sommers,W] |
Full Idea: (reply to 12403) Dear Sir, Your astonishment's odd:/ I am always about in the Quad./ And that's why the tree/ Will continue to be,/ Since observed by Yours faithfully, God.' [anon] | |
From: Will Sommers (talk [2019]) |

From: Will Sommers (talk [2019]) |
12401 | A toper who spies in the distance... [Sommers,W] |
Full Idea: A toper who spies in the distance,/ Striped tigers, will get some assistance/ From reading Descartes,/ Who holds that it's part/ Of his duty to doubt their existence. ... [Leslie Johnson] - (continued in 12402) | |
From: Will Sommers (talk [2019]) |
12410 | There once was a man who said 'Damn!... [Sommers,W] |
Full Idea: There once was a man who said 'Damn!/ It is borne in upon me I am/ An engine that moves/ In predestinate grooves:/ I'm not even a bus, I'm a tram.' [M.E. Hare] | |

10826 | 'Valence' and 'gene' had to be reduced to show their compatibility with physicalism [Field,H] |
Full Idea: 'Valence' and 'gene' were perfectly clear long before anyone succeeded in reducing them, but it was their reducibility and not their clarity before reduction that showed them to be compatible with physicalism. | |
From: Hartry Field (Tarski's Theory of Truth [1972], §5) |
7615 | Field says reference is a causal physical relation between mental states and objects [Field,H, by Putnam] |
Full Idea: In Field's view reference is a 'physicalistic relation', i.e. a complex causal relation between words or mental representations and objects or sets of objects; it is up to physical science to discover what that physicalistic relation is. | |
From: report of Hartry Field (Tarski's Theory of Truth [1972]) by Hilary Putnam - Reason, Truth and History Ch.2 | |
A reaction: I wouldn't hold your breath while the scientists do their job. If physicalism is right then Field is right, but physics seems no more appropriate for giving a theory of reference than it does for giving a theory of music. |
12405 | 'If you're aristocratic,' said Nietzsche... [Sommers,W] |
Full Idea: 'If you're aristocratic,' said Nietzsche,/ 'It's thumbs up, you're OK. Pleased to mietzsche./ If you're working-class bores,/ It's thumbs down and up yours!/ If you don't know your place, then I'll tietzsche.' [Gerry Hamill] | |
