A 'thisness' is a thing's property of being identical with itself (not the possession of self-identity) [Adams,RM]
|
|
Full Idea:
A thisness is the property of being identical with a certain particular individual - not the property that we all share, of being identical with some individual, but my property of being identical with me, your property of being identical with you etc.
|
|
From:
Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 1)
|
|
A reaction:
These philosophers tell you that a thisness 'is' so-and-so, and don't admit that he (and Plantinga) are putting forward a new theory about haecceities, and one I find implausible. I just don't believe in the property of 'being-identical-to-me'.

Things have real essences, but we categorise them according to the ideas we receive [Locke]
|
|
Full Idea:
This I do say, that there are real constitutions in things from whence simple ideas flow, which we observe combin'd in them. But we distinguish particular substances into sorts or genera not by real essences or constitutions, but by observed simple ideas.
|
|
From:
John Locke (Letters to William Molyneux [1692], 1693.01.20)
|
|
A reaction:
This is the clearest statement I can find of Locke's position on essences. He is totally committed to their reality, but strongly aware of the empirical constraints which keep us from direct knowledge of them. He would be amazed by modern discoveries.

If the universe was cyclical, totally indiscernible events might occur from time to time [Adams,RM]
|
|
Full Idea:
There is a temporal argument for the possibility of non-identical indiscernibles, if there could be a cyclical universe, in which each event was preceded and followed by infinitely many other events qualitatively indiscernible from itself.
|
|
From:
Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3)
|
|
A reaction:
The argument is a parallel to Max Black's indiscernible spheres in space. Adams offers the reply that time might be tightly 'curved', so that the repetition was indeed the same event again.

Two events might be indiscernible yet distinct, if there was a universe cyclical in time [Adams,RM]
|
|
Full Idea:
Similar to the argument from spatial dispersal, we can argue against the Identity of Indiscernibles from temporal dispersal. It seems there could be a cyclic universe, ..and thus there could be distinct but indiscernible events, separated temporally.
|
|
From:
Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3)
|
|
A reaction:
See Idea 14509 for spatial dispersal. If cosmologists decided that a cyclical universe was incoherent, would that ruin the argument? Presumably there might even be indistinguishable events in the one universe (in principle!).

Black's two globes might be one globe in highly curved space [Adams,RM]
|
|
Full Idea:
If God creates a globe reached by travelling two diameters in a straight line from another globe, this can be described as two globes in Euclidean space, or a single globe in a tightly curved non-Euclidean space.
|
|
From:
Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 3)
|
|
A reaction:
[my compression of Adams's version of Hacking's response to Black, as spotted by Stalnaker] Hence we save the identity of indiscernibles, by saying we can't be sure that two indiscernibles are not one thing, unusually described.

Haecceitism may or may not involve some logical connection to essence [Adams,RM, by Mackie,P]
|
|
Full Idea:
Moderate Haecceitism says that thisnesses and transworld identities are primitive, but logically connected with suchnesses. ..Extreme Haecceitism involves the rejection of all logical connections between suchness and thisness, for persons.
|
|
From:
report of Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979]) by Penelope Mackie - How Things Might Have Been
|
|
A reaction:
I am coming to the conclusion that they are not linked. That thisness is a feature of our conceptual thinking, and is utterly atomistic and content-free, while suchness is rich and a feature of reality.

Direct reference is by proper names, or indexicals, or referential uses of descriptions [Adams,RM]
|
|
Full Idea:
Direct reference is commonly effected by the use of proper names and indexical expressions, and sometimes by what has been called (by Donnellan) the 'referential' use of descriptions.
|
|
From:
Robert Merrihew Adams (Primitive Thisness and Primitive Identity [1979], 2)
|
|
A reaction:
One might enquire whether the third usage should be described as 'direct', but then I am not sure that there is much of a distinction between references which are or are not 'direct'. Either you (or a sentence) refer or you (or it) don't.

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').
