4451 | If properties are universals, what distinguishes two things which have identical properties? [Moreland] |
Full Idea: If properties are universals, what account can be given of the individuation of two entities that have all their pure properties in common? | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: Is this a big problem? Maybe only a space-time location can do it. Or, in the nice case where the universe is just two identical spheres, it may be impossible. |
4453 | One realism is one-over-many, which may be the model/copy view, which has the Third Man problem [Moreland] |
Full Idea: One version of realism says that the universal does not enter into the being of its instances, and thus is a One-Over-Many. One version of this is the model/copy view, but this is not widely held, because of difficulties such as the Third Man Argument. | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: This presumably arises if the model is held to have the properties of the copy (self-predication), and looks like a bad theory |
4464 | Realists see properties as universals, which are single abstract entities which are multiply exemplifiable [Moreland] |
Full Idea: Traditional realism is the view that a property is a universal construed as a multiply exemplifiable abstract entity that is a numerically identical constituent in each of its instances. | |
From: J.P. Moreland (Universals [2001], Ch.4) | |
A reaction: Put like that, it seems hard to commit oneself fully to realism. How can two red buses contain one abstract object spread out between them. Common sense says there are two 'rednesses' which resemble one another, which is a version of nominalism. |
4450 | The traditional problem of universals centres on the "One over Many", which is the unity of natural classes [Moreland] |
Full Idea: Historically the problem of universals has mainly been about the "One over Many", which involves giving an account of the unity of natural classes. | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: This still strikes me as the main problem (rather than issues of language). If universals are not natural, they must be analysed as properties, which break down into causation, which is seen as a human convention. |
4449 | Evidence for universals can be found in language, communication, natural laws, classification and ideals [Moreland] |
Full Idea: Those who believe in universals appeal to the meaningfulness of language, the lawlike nature of causation, the inter-subjectivity of thinking, our ability to classify new entities, gradation, and the need for perfect standards or paradigms. | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: Of these, language and communication ought to be explicable by convention, but classification and natural laws look to me like the best evidence. |
4454 | The One-In-Many view says universals have abstract existence, but exist in particulars [Moreland] |
Full Idea: Another version of realism says is One-In-Many, where the universal is not another particular, but is literally in the instances. The universal is an abstract entity, in the instances by means of a primitive non-spatiotemporal tie of predication. | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: This sounds like Aristotle (and is Loux's view of properties and relations). If they are abstract, why must they be confined to particulars? |
4452 | Maybe universals are real, if properties themselves have properties, and relate to other properties [Moreland] |
Full Idea: Realism about universals is supported by the phenomenon of abstract reference - that is the fact that properties themselves have properties ('red is a colour'), and stand in relation to other properties ('red is more like orange than like blue'). | |
From: J.P. Moreland (Universals [2001], Ch.1) | |
A reaction: While a property may be an obviously natural feature, properties of properties seem more likely to be the produce of human perception and convention. It is a good argument, though. |
4467 | A naturalist and realist about universals is forced to say redness can be both moving and stationary [Moreland] |
Full Idea: If a property is held to be at the location of the particular, then if there are two objects having the same property, and one object is stationary and the other is moving, the realist is forced to say that the universal is both moving and at rest. | |
From: J.P. Moreland (Universals [2001], Ch.4) | |
A reaction: The target of this comment is D.M.Armstrong. The example nicely illustrates the problem of trying to combine science and metaphysics. It pushes you back to Platonism, but that seems wrong too… |
4469 | There are spatial facts about red particulars, but not about redness itself [Moreland] |
Full Idea: When one attends to something existing in space, one attends to an instance of redness, not to redness itself (which is a colour, which resembles orange). The facts about red itself are not spatial facts, but are traditionally seen as a priori synthetic. | |
From: J.P. Moreland (Universals [2001], Ch.4) | |
A reaction: This is the fact that properties can themselves have properties (and so on?), which seems to take us further and further from the natural world. |
4468 | How could 'being even', or 'being a father', or a musical interval, exist naturally in space? [Moreland] |
Full Idea: Many properties (being even) and relations (musical intervals, being a father) are such that it is not clear what it would mean to take them as natural things existing in space. | |
From: J.P. Moreland (Universals [2001], Ch.4) | |
A reaction: 'Being even' certainly seems to be a property, and it is a struggle to see how it could exist in space, unless it is a set of actual or potential brain states. |
4472 | Redness is independent of red things, can do without them, has its own properties, and has identity [Moreland] |
Full Idea: Four arguments for Platonism: 1) there are truths about redness (it's a colour) even if nothing red exists, 2) redness does not depend on particulars, 3) most universals are at some time not exemplified, 4) universals satisfy the criteria of existence. | |
From: J.P. Moreland (Universals [2001], Ch.6) | |
A reaction: This adds up to quite a good case, particularly the point that things can be said about redness which are independent of any particular, but the relationships between concepts and the brain seems at the heart of the problem. |
