If we were to find a substance that looks, feels and otherwise functions like water, but had a chemical structure other than H₂O, it would not be water. — Banno
There's a bit of a puzzle here for me, looking back. Why would anyone have thought that it was easier to use properties to set up names, rather than names to set up properties? As if it was easier to deal with "orange", "skin", and "narcissist" rather than "Trump". — Banno
so we end up having to allow silly things like 'if Nixon were a golf ball...' — andrewk
More assertions without argument; this is getting boring. Might as well leave it there if you can't come up with any cogent argument that actually addresses what I have written. — Janus
(for me the 'in this world' is taken for granted, since I believe all reference in possible worlds or counterfactuals must first be established in this world). — Janus
The general denotation of 'Trump' is Trump, and no particular entity has been specified; so 'Trump' is more properly equivalent to 'an entity called 'Trump''. — Janus
Sure, but the point is that the semantic value of names can be expressed, and best understood, in terms of descriptions as I think I have shown above. — Janus
Perhaps if you could restate your argument for why Trump is not logically equivalent to an entity called 'Trump' — Janus
since my contention has been that one of the ways they get established is by description I can't see how it is not relevant to the question. — Janus
The point of what I said there was to show that 'Trump' and 'an entity called Trump' are logically equivalent. — Janus
The only other way I could think of would be pointing at the individual, or showing a photograph and the like; in other words: ostention. In the case of "baptism", the original act of naming, for those present it would be ostention and for anyone who subsequently met the baptized entity and was told 'it's name is X' it would be ostention also. For remote figures and historical figures, the referent of the name is established by description, and perhaps by ostention in the form of images: photographs if there are any, drawings, prints or paintings. — Janus
Yes, but all you seem to be saying here is that once the particular entity called 'Trump' that is being referred to in this world is established (by ostention or sufficient description) then we can refer to that entity by the name 'Trump' across possible worlds. — Janus
So, the point is that once we have established the entity being referred to in this world, by sufficiently definite description, we can use that definite description as it obtained in this world at a particular place, time and date, to establish the same entity referred to across possible worlds. We need such place/time/date/-indexed descriptions to establish precisely which entity is being referred to in the first place; just a name is not enough. — Janus
The former (without any further qualification or description) refers to anyone called 'Trump' — Janus
Yes, that's right. Of course we say that Trump would still be Trump even if he had not been called that, and we say that because he has been called that. But we wouldn't say that if he hadn't been called Trump. All we are really saying is that a particular entity is a particular entity regardless of what you call it, and that is tautologously true. — Janus
You seem to be conflating the statement 'it is necessary that the entity that is called Trump is the entity that is called Trump' with the statement 'it is contingent that the entity that is called Trump is called Trump'. — Janus
If Kripke is not disagreeing then those I have been arguing with have been arguing about nothing. — Janus
But if that were true then Kripke would not really be saying anything that is itself more than trivial. — Janus
'N' and 'the entity called N' seem to me to be logically equivalent. — Janus
The fact of the name definitely referring is a fact of this world, and it is on account of that fact that the name can be used to definitely refer to the entity it designates in counterfactual or possible scenarios. — Janus
So, the name Donald Trump by itself does not definitely designate any entity, since there could be any number of entities (including my car) named Donald Trump. — Janus
There are two points, which you seem unable to grasp. The first is that names only rigidly designate by virtue of descriptive or ostensive contexts. The second is that names are themselves shorthand descriptions, the definiteness of which depend on further description. 'Donald Trump' is equivalent to 'the entity named 'Donald Trump' and doesn't rigidly designate until further information is provided: 'the man named Donald Trump who was POTUS at December 5 2019' for example; or 'the car that was named Donald Trump at (insert latitude and longitude) at (insert precise time)'. — Janus
No, because the referent of the DD was the Republican candidate. If the Dem candidate was named Peter Nixon, or even Richard Milhouse Nixon, that person would not be the referent of the DD. — andrewk
I didn't say it was; I said it was contingent upon the man named Donald Trump being so named in this world. — Janus
All reference in counterfactual discourse is established by reference to the actual world; and this goes equally for names as it does definite descriptions. — Janus
I could name my car 'Donald Trump' if I wished to. In the case where multiple entities are named the same, then further qualifications (descriptions) are required to establish which of those entities is being referred to (except in ostensive contexts as I have already acknowledged many times). — Janus
But all modal logic depends on what is the case in this world, and since there is only one country called Albania bordering Greece, and in fact only one country called Albania: "A country called Albania that borders Greece" and even "a country called Albania" picks out just one entity and thus should be considered to be a definite description. — Janus
The same thing applies when you say that 'Donald Trump' is a rigid designator (leaving aside for the sake of the argument the objection that the name does not pick out just one entity if more than one person is called Donald Trump); it is only contingently so because the man named Donald Trump was named Donald Trump. — Janus
'A country called Albania which borders Greece' is a definite description because there is only one of them; the logic is obvious. — Janus
"The country called Albania, which borders Greece" is a definite description by your own definition. — Janus
It is also a rigid designator — Janus
whereas 'Albania' by itself is not a rigid designator except in principle, because it could be the name of a country, a person, a pet, a type of vacuum cleaner and so on and on. — Janus
have not found satisfactory answers to, for example, why definite descriptions cannot be rigid designators. — Janus
There is only one actual world. Every true sentence about the stuff in it is necessarily true. — frank
