15538 | Semantic indecision explains vagueness (if we have precisifications to be undecided about) [Lewis] |
Full Idea: Semantic indecision will suffice to explain the phenomenon of vagueness. [note] Provided that there exist the many precisifications for us to be undecided between. If you deny this, you will indeed have need of vague objects. | |
From: David Lewis (Many, but almost one [1993], 'Two solutions') | |
A reaction: [He mentions Van Inwagen 1990:213-83] There seem to be three solutions to vague objects: that they really are vague, that they are precise but we can't know precisely, or Lewis's view. I like Lewis's view. Do animals have any problem with vagueness? |
13795 | Properties only have identity in the context of their contraries [Elder] |
Full Idea: The very being, the identity, of any property consists at least in part in its contrasting as it does with its own proper contraries. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 2.4) | |
A reaction: See Elder for the details of this, but the idea that properties can only be individuated contextually sounds promising. |
15537 | If cats are vague, we deny that the many cats are one, or deny that the one cat is many [Lewis] |
Full Idea: To deny that there are many cats on the mat (because removal of a few hairs seems to produce a new one), we must either deny that the many are cats, or else deny that the cats are many. ...I think both alternatives lead to successful solutions. | |
From: David Lewis (Many, but almost one [1993], 'The paradox') | |
A reaction: He credits the problem to Geach (and Tibbles), and says it is the same as Unger's 'problem of the many' (Idea 15536). |
13798 | Maybe we should give up the statue [Elder] |
Full Idea: Some contemporary metaphysicians infer that one of the objects must go, namely, the statue. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 7.2) | |
A reaction: [He cites Zimmerman 1995] This looks like a recipe for creating a vast gulf between philosophers and the rest of the population. If it is right, it makes the true ontology completely useless in understanding our daily lives. |
15536 | We have one cloud, but many possible boundaries and aggregates for it [Lewis] |
Full Idea: Many surfaces are equally good candidates to be boundaries of a cloud; therefore many aggregates of droplets are equally good candidates to be the cloud. How is it that we have just one cloud? And yet we do. This is Unger's (1980) 'problem of the many'. | |
From: David Lewis (Many, but almost one [1993], 'The problem') | |
A reaction: This is the problem of vague objects, as opposed to the problem of vague predicates, or the problem of vague truths, or the problem of vague prepositions (like 'towards'). |
13797 | The loss of an essential property means the end of an existence [Elder] |
Full Idea: The loss of any essential property must amount to the end of an existence. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3) | |
A reaction: This is orthodoxy for essentialists, and I presume that Aristotle would agree, but I have a problem with the essence of a great athlete, who then grows old. Must we say that they lose their identity-as-an-athlete? |
13794 | Essential properties by nature occur in clusters or packages [Elder] |
Full Idea: Essential properties by nature occur in clusters or packages. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 2.2) | |
A reaction: Elder proposes this as his test for the essentialness of a property - his Test of Flanking Uniformities. A nice idea. |
13796 | Essential properties are bound together, and would be lost together [Elder] |
Full Idea: The properties of any essential nature are bound together....[122] so any case in which one of our envisioned familiar objects loses one of its essential properties will be a case in which it loses several. | |
From: Crawford L. Elder (Real Natures and Familiar Objects [2004], 3) | |
A reaction: This sounds like a fairly good generalisation rather than a necessary truth. Is there a natural selection for properties, so that only the properties which are able to bind to others to form teams are able to survive and flourish? |
15539 | Basic to pragmatics is taking a message in a way that makes sense of it [Lewis] |
Full Idea: The cardinal principle of pragmatics is that the right way to take what is said, if at all possible, is the way that makes sense of the message. | |
From: David Lewis (Many, but almost one [1993], 'A better solution') | |
A reaction: Thus when someone misuses a word, suggesting nonsense, we gloss over it, often without even mentioning it, because the underlying sense is obvious. A good argument for the existence of propositions. Lewis doesn't mention truth. |
7903 | The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna] |
Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom. | |
From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88) | |
A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate'). |
