5831 | The new view is that "water" is a name, and has no definition [Schwartz,SP] |
Full Idea: Perhaps the modern view is best expressed as saying that "water" has no definition at all, at least in the traditional sense, and is a proper name of a specific substance. | |
From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
A reaction: This assumes that proper names have no definitions, though I am not clear how we can grasp the name 'Aristotle' without some association of properties (human, for example) to go with it. We need a definition of 'definition'. |
17325 | Truth-maker theory can't cope with non-causal dependence [Liggins] |
Full Idea: My charge is that truth-maker theory cannot be integrated into an attractive general account of non-causal dependence. | |
From: David Liggins (Truth-makers and dependence [2012], 10.6) | |
A reaction: [You'll have to read Liggins to see why] |
17318 | Truthmakers for existence is fine; otherwise maybe restrict it to synthetic truths? [Liggins] |
Full Idea: Many philosophers agree that true existential propositions have a truth-maker, but some go further, claiming that every true proposition has a truth-maker. More cautious theorists specify a class of truths, such as synthetic propositions. | |
From: David Liggins (Truth-makers and dependence [2012], 10.1) | |
A reaction: [compressed; Armstrong is the ambitious one, and Rodriguez-Pereyra proposes the synthetic propositions] Presumably synthetic propositions can make negative assertions, which are problematic for truth-makers. |
5829 | We refer to Thales successfully by name, even if all descriptions of him are false [Schwartz,SP] |
Full Idea: We can refer to Thales by using the name "Thales" even though perhaps the only description we can supply is false of him. | |
From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
A reaction: It is not clear what we would be referring to if all of our descriptions (even 'Greek philosopher') were false. If an archaeologist finds just a scrap of stone with a name written on it, that is hardly a sufficient basis for successful reference. |
5830 | The traditional theory of names says some of the descriptions must be correct [Schwartz,SP] |
Full Idea: The traditional theory of proper names entails that at least some combination of the things ordinarily believed of Aristotle are necessarily true of him. | |
From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §III) | |
A reaction: Searle endorses this traditional theory. Kripke and co. tried to dismiss it, but you can't. If all descriptions of Aristotle turned out to be false (it was actually the name of a Persian statue), our modern references would have been unsuccessful. |
17320 | Either p is true or not-p is true, so something is true, so something exists [Liggins] |
Full Idea: Either p or not-p. If p, then the proposition 'p' is true. If not p, then the proposition 'not p' is true. Either way, something is true. Thus something exists. | |
From: David Liggins (Truth-makers and dependence [2012], 10.3 n5) | |
A reaction: Liggins offers this dodgy argument as an objection to conceptual truths having truth-makers. |
17326 | The dependence of {Socrates} on Socrates involves a set and a philosopher, not facts [Liggins] |
Full Idea: The dependence of {Socrates} on Socrates appears to involve a set and a philosopher, neither of which is a fact. | |
From: David Liggins (Truth-makers and dependence [2012], 10.6) | |
A reaction: He points out that defenders of facts as the basis of dependence could find a suitable factual paraphrase here. Socrates is just Socrates, but the singleton has to be understood in a particular way to generate the dependence. |
17327 | Non-causal dependence is at present only dimly understood [Liggins] |
Full Idea: Non-causal dependence is at present only dimly understood. | |
From: David Liggins (Truth-makers and dependence [2012], 10.8) | |
A reaction: Not very helpful, you may be thinking, but it is always helpful to know where we have got to in the enquiry. |
17322 | Necessities supervene on everything, but don't depend on everything [Liggins] |
Full Idea: Necessities supervene upon everything, but they do not depend on everything. | |
From: David Liggins (Truth-makers and dependence [2012], 10.4) | |
A reaction: I'm not sure if merely existing together counts as sufficiently close to be 'supervenience'. If 2+2 necessitates 4, that hardly seems to 'supervene' on the Eiffel Tower. If so, how close must things be to qualify for supervenience? |
15785 | Our commitments are to an 'ontology', but also to an 'ideology', or conceptual system [Hintikka] |
Full Idea: We must distinguish between what we are committed to existing in the actual world or a possible world ('ontology'), and what we are committed to as a part of our ways of dealing with the world conceptually, as a part of our conceptual system ('ideology'). | |
From: Jaakko Hintikka (Semantics for Propositional Attitudes [1969], p.95), quoted by William Lycan - The Trouble with Possible Worlds 02 | |
A reaction: I think this is the most illuminating idea I have read on the subject of ontological commitment. I'm fighting for the idea that what we think is true should be kept separate from what we think exists. Ideology is a nice addition to the mix. |
15786 | Commitment to possible worlds is part of our ideology, not part of our ontology [Hintikka] |
Full Idea: Quantification over members of one particular world is a measure of ideology, quantification that crosses possible worlds is often a measure of ideology. | |
From: Jaakko Hintikka (Semantics for Propositional Attitudes [1969], p.95), quoted by William Lycan - The Trouble with Possible Worlds 02 | |
A reaction: I like this. See Idea 15785 for the underlying distinction. It leaves the question open of what we might mean by 'ideological commitment'. |
17324 | 'Because' can signal an inference rather than an explanation [Liggins] |
Full Idea: 'Because' can signal an inference rather than an explanation. | |
From: David Liggins (Truth-makers and dependence [2012], 10.5) | |
A reaction: Aristotle starts from words like 'why?', but it can be a deceptive approach to explanation. |
17321 | Value, constitution and realisation are non-causal dependences that explain [Liggins] |
Full Idea: 'It is wrong because it produces pain for fun', and 'these constitute a table because they are arranged tablewise', and 'tea is poisonous because it contains arsenic' are clearly non-causal uses of 'because', and neither are they conceptual. | |
From: David Liggins (Truth-makers and dependence [2012], 10.4) | |
A reaction: The general line seems to be that any form of determination will underwrite an explanation. He talks later of the 'wrongmaker' and 'poisonmaker' relationships to add to the 'truthmaker'. The table example is the 'object-maker' dependence relation. |
17323 | If explanations track dependence, then 'determinative' explanations seem to exist [Liggins] |
Full Idea: If explanation often tracks dependence, then we have a theoretical reason to expect such explanations to exist. Let us call such explanations 'determinative'. | |
From: David Liggins (Truth-makers and dependence [2012], 10.4) | |
A reaction: There seems to be an emerging understanding that this 'determination' relation is central to all of explanation - with causal explanations, for example, being a particular instance of it. I like it. These are real, not conventional, explanations. |
5826 | The intension of "lemon" is the conjunction of properties associated with it [Schwartz,SP] |
Full Idea: The conjunction of properties associated with a term such as "lemon" is often called the intension of the term "lemon". | |
From: Stephen P. Schwartz (Intro to Naming,Necessity and Natural Kinds [1977], §II) | |
A reaction: The extension of "lemon" is the set of all lemons. At last, a clear explanation of the word 'intension'! The debate becomes clear - over whether the terms of a language are used in reference to ideas of properties (and substances?), or to external items. |
