Reference to a person's emotions is often essential to understanding their actions [Williams,B]
|
|
Full Idea:
The reference to a man's emotions has a significance for our understanding of his moral sincerity, not as a substitute for or addition to how he acts, but as, on occasion, underlying our understanding of how he acts.

|
From:
Bernard Williams (Morality and the emotions [1965], p.223)
|
|
A reaction:
Williams aims to rescue emotion from the emotivists, and replace it at the centre of traditional modes of moral judgement. I suppose we could assess one rogue robot as behaving 'badly' in a community of robots.

Moral education must involve learning about various types of feeling towards things [Williams,B]
|
|
Full Idea:
If moral education does not revolve around what to fear, to be angry about, to despise, and where to draw the line between kindness and a stupid sentimentality - I do not know what it is. (Though there are principles, of truth-telling and justice).

From:
Bernard Williams (Morality and the emotions [1965], p.225)
|
|
A reaction:
He cites Aristotle as the obvious source of this correct idea. The examples of principle both require us to place a high value on truth and justice, and not just follow rules in the style of arithmetic.

Nowadays abstractions are defined as non-spatial, causally inert things [Rosen]
|
|
Full Idea:
If any characterization of the abstract deserves to be regarded as the modern standard one, it is this: an abstract entity is a non-spatial (or non-spatiotemporal) causally inert thing. This view presents a number of perplexities...

From:
Gideon Rosen (Abstract Objects [2001], 'Non-spat')
|
|
A reaction:
As indicated in other ideas, the problem is that some abstractions do seem to be located somewhere in space-time, and to have come into existence, and to pass away. I like 'to exist is to have causal powers'. See Ideas 5992 and 8300.

Functional terms can pick out abstractions by asserting an equivalence relation [Rosen]
|
|
Full Idea:
On Frege's suggestion, functional terms that pick out abstract expressions (such as 'direction' or 'equinumeral') have a typical form of f(a) = f(b) iff aRb, where R is an equivalence relation, a relation which is reflexive, symmetric and transitive.
|
|
From:
Gideon Rosen (Abstract Objects [2001], 'Way of Abs')
|
|
A reaction:
[Wright and Hale are credited with the details] This has become the modern orthodoxy among the logically-minded. Examples of R are 'parallel' or 'just as many as'. It picks out an 'aspect', which isn't far from the old view.

Abstraction by equivalence relationships might prove that a train is an abstract entity [Rosen]
|
|
Full Idea:
It seems possible to define a train in terms of its carriages and the connection relationship, which would meet the equivalence account of abstraction, but demonstrate that trains are actually abstract.
|
|
From:
Gideon Rosen (Abstract Objects [2001], 'Way of Abs')
|
|
A reaction:
[Compressed. See article for more detail] A tricky example, but a suggestive line of criticism. If you find two physical objects which relate to one another reflexively, symmetrically and transitively, they may turn out to be abstract.
