Logic guides thinking, but it isn't a substitute for it [Rumfitt]
|
|
Full Idea:
Logic is part of a normative theory of thinking, not a substitute for thinking.
|
|
From:
Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.13)
|
|
A reaction:
There is some sort of logicians' dream, going back to Leibniz, of a reasoning engine, which accepts propositions and outputs inferences. I agree with this idea. People who excel at logic are often, it seems to me, modest at philosophy.

Vague membership of sets is possible if the set is defined by its concept, not its members [Rumfitt]
|
|
Full Idea:
Vagueness in respect of membership is consistency with determinacy of the set's identity, so long as a set's identity is taken to consist, not in its having such-and-such members, but in its being the extension of a concept.
|
|
From:
Ian Rumfitt (The Logic of Boundaryless Concepts [2007], p.5)
|
|
A reaction:
I find this view of sets much more appealing than the one that identifies a set with its members. The empty set is less of a problem, as well as non-existents. Logicians prefer the extensional view because it is tidy.

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'.
