If Hume's Principle can define numbers, we needn't worry about its truth [Fine,K]
|
|
Full Idea:
Neo-Fregeans have thought that Hume's Principle, and the like, might be definitive of number and therefore not subject to the usual epistemological worries over its truth.
|
|
From:
Kit Fine (Precis of 'Limits of Abstraction' [2005], p.310)
|
|
A reaction:
This seems to be the underlying dream of logicism - that arithmetic is actually brought into existence by definitions, rather than by truths derived from elsewhere. But we must be able to count physical objects, as well as just counting numbers.

Hume's Principle is either adequate for number but fails to define properly, or vice versa [Fine,K]
|
|
Full Idea:
The fundamental difficulty facing the neo-Fregean is to either adopt the predicative reading of Hume's Principle, defining numbers, but inadequate, or the impredicative reading, which is adequate, but not really a definition.
|
|
From:
Kit Fine (Precis of 'Limits of Abstraction' [2005], p.312)
|
|
A reaction:
I'm not sure I understand this, but the general drift is the difficulty of building a system which has been brought into existence just by definition.

An abstraction principle should not 'inflate', producing more abstractions than objects [Fine,K]
|
|
Full Idea:
If an abstraction principle is going to be acceptable, then it should not 'inflate', i.e. it should not result in there being more abstracts than there are objects. By this mark Hume's Principle will be acceptable, but Frege's Law V will not.
|
|
From:
Kit Fine (Precis of 'Limits of Abstraction' [2005], p.307)
|
|
A reaction:
I take this to be motivated by my own intuition that abstract concepts had better be rooted in the world, or they are not worth the paper they are written on. The underlying idea this sort of abstraction is that it is 'shared' between objects.

'Content' gives the standard modal profile, and 'character' gives rules for a context [Kaplan, by Schroeter]
|
|
Full Idea:
Kaplan sees two aspects of meaning, the 'content', reflecting a thing's modal profile, which is modelled by standard possible worlds semantics, and 'character', giving rules for different contexts. Proper names have constant character; indexicals vary.
|
|
From:
report of David Kaplan (Demonstratives [1989]) by Laura Schroeter - Two-Dimensional Semantics 1.1.1
|
|
A reaction:
This gives rise to 2-D matrices for representing meaning, and the possible worlds are used twice, for evaluating meaning and then for evaluating context of use. I've always been struck by the two-dimensional semantics of passwords.

Consequentialism emphasises value rather than obligation in morality [Scruton]
|
|
Full Idea:
According to consequentialism, the fundamental concept of morality is not obligation (deontological ethics) but value (axiological ethics).
|
|
From:
Roger Scruton (A Dictionary of Political Thought [1982], 'consequentialism')
|
|
A reaction:
These two views could come dramatically apart, in wartime, or in big ecological crises, or in a family breakup, or in religious disputes. Having identified the pair so clearly, why can we not aim for a civilised (virtuous) balance between the two?

Altruism is either emotional (where your interests are mine) or moral (where they are reasons for me) [Scruton]
|
|
Full Idea:
Two distinct motives go by the name of altruism: the emotions of liking, love and friendship, making another's interest automatically mine; and the moral motive of respect or considerateness, where another's interests become reasons for me, but not mine.
|
|
From:
Roger Scruton (A Dictionary of Political Thought [1982], 'altruism')
|
|
A reaction:
The second one has a strongly Kantian flavour, with its notion of impersonal duty. Virtue theorists will aspire to achieve the first state rather than the second, because good actions are then actively desired, and give pleasure to the doer.

Liberals focus on universal human freedom, natural rights, and tolerance [Scruton, by PG]
|
|
Full Idea:
Liberalism believes (roughly) in the supremacy of the individual, who has freedom and natural rights; it focuses on human, not divine affairs; it claims rights and duties are universal; and it advocates tolerance in religion and morality.
|
|
From:
report of Roger Scruton (A Dictionary of Political Thought [1982], 'liberalism') by PG - Db (ideas)
|
|
A reaction:
I find it hard to disagree with these principles, but the upshot in practice is often an excessive commitment to freedom and tolerance, because people fail to realise the subtle long-term erosions of society that can result.

The issue of abortion seems insoluble, because there is nothing with which to compare it [Scruton]
|
|
Full Idea:
The issue of abortion is intractable, partly because of the absence of any other case to which it can be assimilated.
|
|
From:
Roger Scruton (A Dictionary of Political Thought [1982], 'abortion')
|
|
A reaction:
This is the legalistic approach to the problem, which always looks for precedents and comparisons. All problems must hav solutions, though (mustn't they?). The problem, though, is not the value of the foetus, but the unique form of 'ownership'.
