Classical negation is circular, if it relies on knowing negation-conditions from truth-conditions [Dummett]
|
|
Full Idea:
Explanations of classical negation assume that knowing what it is for the truth-condition of some statement to obtain, independently of recognising it to obtain, we thereby know what it is for it NOT to obtain; but this presupposes classical negation.

From:
Michael Dummett (The Logical Basis of Metaphysics [1991], p.299), quoted by Ian Rumfitt - The Boundary Stones of Thought 1.1
|
|
A reaction:
[compressed wording] This is Dummett explaining why he prefers intuitionistic logic, with its doubts about double negation.

'One' can mean undivided and not a multitude, or it can add measurement, giving number [Aquinas]
|
|
Full Idea:
There are two sorts of one. There is the one which is convertible with being, which adds nothing to being except being undivided; and this deprives of multitude. Then there is the principle of number, which to the notion of being adds measurement.

From:
Thomas Aquinas (Quaestiones de Potentia Dei [1269], q3 a16 ad 3-um)
|
|
A reaction:
[From a lecture handout] I'm not sure I understand this. We might say, I suppose, that insofar as water is water, it is all one, but you can't count it. Perhaps being 'unified' and being a 'unity' are different?

Modern attention has moved from the intrinsic properties of art to its relational properties [Lamarque/Olson]
|
|
Full Idea:
In modern discussions, rather than look for intrinsic properties of objects, including aesthetic or formal properties, attention has turned to extrinsic or relational properties, notably of a social, historical, or 'institutional' nature.

|
From:
Lamargue,P/Olson,SH (Introductions to 'Aesthetics and the Phil of Art' [2004], Pt 1)
|
|
A reaction:
Lots of modern branches of philosophy have made this move, which seems to me like a defeat. We want to know why things have the relations they do. Just mapping the relations is superficial Humeanism.

Early 20th cent attempts at defining art focused on significant form, intuition, expression, unity [Lamarque/Olson]
|
|
Full Idea:
In the early twentieth century there were numerous attempts at defining the essence art. Significant form, intuition, the expression of emotion, organic unity, and other notions, were offered to this end.
|
|
From:
Lamargue,P/Olson,SH (Introductions to 'Aesthetics and the Phil of Art' [2004], Pt 1)
|
|
A reaction:
As far as I can see the whole of aesthetics was demolished in one blow by Marcel Duchamp's urinal. Artists announce: we will tell you what art is; you should just sit and listen. Compare the invention of an anarchic sport.

The dualistic view says works of art are either abstract objects (types), or physical objects [Lamarque/Olson]
|
|
Full Idea:
The dualistic view of the arts holds that works of art come in two fundamentally different kinds: those that are abstract entities, i.e. types, and those that are physical objects (tokens).
|
|
From:
Lamargue,P/Olson,SH (Introductions to 'Aesthetics and the Phil of Art' [2004], Pt 2)
|
|
A reaction:
Paintings are the main reason for retaining physical objects. Strawson 1974 argues that paintings are only physical because we cannot yet perfectly reproduce them. I agree. Works of art are types, not tokens.
