8502 | Realism doesn't explain 'a is F' any further by saying it is 'a has F-ness' [Devitt] |
Full Idea: Realists feel that the one-place predication 'a is F' leaves something unexplained, yet all that is offered is a two-place predication (a relational statement). There is an equal problem about 'a having F-ness'. | |
From: Michael Devitt ('Ostrich Nominalism' or 'Mirage Realism'? [1980], p.97) | |
A reaction: I think this is a key argument on the nominalist side - the denial that the theory of universals actually makes any progress at all in giving an explanation of what is going on around here. Platonist have the problem of 'partaking'. |
8503 | The particular/universal distinction is unhelpful clutter; we should accept 'a is F' as basic [Devitt] |
Full Idea: Talk of 'particulars' and 'universals' clutters the landscape without adding to our understanding. We should rest with the basic fact that a is F. | |
From: Michael Devitt ('Ostrich Nominalism' or 'Mirage Realism'? [1980], p.98) | |
A reaction: Ramsey was first to challenge the basic distinction. I find the approach of Quine and Devitt unsatisfactory. We abandon explanation when it is totally hopeless, but that is usually in the face of complexity. Properties are difficult but simple. |
8501 | Quineans take predication about objects as basic, not reference to properties they may have [Devitt] |
Full Idea: For 'a and b have the same property, F-ness' the Quinean Nominalist has a paraphrase to hand: 'a and b are both F'. ..In denying that this object need have properties, the Quinean is not denying that it really is F. | |
From: Michael Devitt ('Ostrich Nominalism' or 'Mirage Realism'? [1980], p.95) | |
A reaction: The question that remains is why 'F' is used of both a and b. We don't call a and b 'a', because they are different. Quine falls back on resemblance. I suspect Quineans of hiding behind the semantics. |
2602 | What experience could prove 'If a=c and b=c then a=b'? [Descartes] |
Full Idea: Please tell me what the corporeal motion is that is capable of forming some common notion to the effect that 'things which are equal to a third thing are equal to each other'. | |
From: René Descartes (Comments on a Certain Broadsheet [1644], p.366) |
2600 | The mind's innate ideas are part of its capacity for thought [Descartes] |
Full Idea: I have never written or taken the view that the mind requires innate ideas which are something distinct from its own faculty of thinking. | |
From: René Descartes (Comments on a Certain Broadsheet [1644], p.365) |
2601 | Qualia must be innate, because physical motions do not contain them [Descartes] |
Full Idea: The ideas of pains, colours, sounds etc. must be all the more innate if, on the occasion of certain corporeal motions, our mind is to be capable of representing them to itself, for there is no similarity between these ideas and the corporeal motions. | |
From: René Descartes (Comments on a Certain Broadsheet [1644], p.365) | |
A reaction: Simple and brilliant! We know perfectly well that there is no redness zooming through the air from a tomato (or the air would be pink!). Redness occurs when the light arrives, so we add the redness, so it is innate. |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
