6070 | Existence is a primary quality, non-existence a secondary quality [McGinn] |
Full Idea: Existence is like a primary quality; non-existence is like a secondary quality. | |
From: Colin McGinn (Logical Properties [2000], Ch.2 n29) | |
A reaction: Since McGinn thinks existence really is a property, and hence, presumably, a predicate, I don't quite see why he uses the word "like". A nicely pithy and thought-provoking remark. |
6062 | Existence can't be analysed as instantiating a property, as instantiation requires existence [McGinn] |
Full Idea: Paraphrasing existence statements into statements about the instantiation of a property does not establish that existence is not a predicate, since the notion of instantiation must be taken to have existence built into it. | |
From: Colin McGinn (Logical Properties [2000], Ch.2) | |
A reaction: Thank you, Colin McGinn! This now strikes me as so obvious that it is astonishing that for the whole of the twentieth century no one seems to have said it. For a century philosophers had swept the ontological dirt under the mat. |
6065 | We can't analyse the sentence 'something exists' in terms of instantiated properties [McGinn] |
Full Idea: The problems of the orthodox view are made vivid by analysis of the sentence 'something exists'; this is meaningful and true, but what property are we saying is instantiated here? | |
From: Colin McGinn (Logical Properties [2000], Ch.2) | |
A reaction: A very nice point. McGinn claims that existence is a property, a very generalised one. Personally I don't think anyone is even remotely clear what a property is, so the whole discussion is a bit premature. Must properties have causal powers? |
16051 | Life has a new supervenient relation, which alters its underlying physical events [Morgan,L] |
Full Idea: When some new kind of relatedness is supervenient (say at the level of life), the way in which the physical events which are involved run their course is different in virtue of its presence. | |
From: Lloyd Morgan (Emergent Evolution [1923], pp.15-16), quoted by Terence Horgan - From Supervenience to Superdupervenience 1 | |
A reaction: This is a clear assertion of 'downward causation' at the first introduction of 'supervenience', supporting 'emergentism' about life and mind. That is, the newly-emerged feature has new causal powers that affect the physical system from outside. Wrong! |
22427 | To explain object qualities, primary qualities must be more than mere sources of experience [McGinn] |
Full Idea: In order that we have available an explanation of the qualities of objects we need to be able to conceive primary qualities as consisting in something other than powers to produce experiences. | |
From: Colin McGinn (Subjective View: sec qualities and indexicals [1983], 6 n 52) | |
A reaction: I suppose if the qualities are nothing more than the source of the experiences, that is Kant's noumenon. Nothing more could be said. The seems to be a requirement for tacit inference here. We infer the interior of the tomato. |
6082 | If causal power is the test for reality, that will exclude necessities and possibilities [McGinn] |
Full Idea: Whether my body weight is necessary or contingent makes no difference at all to my causal powers, so modality is epiphenomenal; if you took causal potential as a test of reality you would have to declare modes unreal. | |
From: Colin McGinn (Logical Properties [2000], Ch.4) | |
A reaction: We could try analysing modality into causal terms, as Lewis proposes with quantification across worlds, or as Quine proposes by reduction to natural regularities. I am not sure what it would mean to declare that modes are 'real'. |
6075 | Facts are object-plus-extension, or property-plus-set-of-properties, or object-plus-property [McGinn] |
Full Idea: A fact may be an object and an extension (Quine's view), or a property and a set of properties, or an object and a property; the view I favour is the third one, which seems the most natural. | |
From: Colin McGinn (Logical Properties [2000], Ch.3) | |
A reaction: Personally I tend to use the word 'fact' in a realist and non-linguistic way. There must be innumerable inexpressible facts, such as the single pattern made by all the particles of the universe. McGinn seems to be talking of 'atomic facts'. See Idea 6111. |
