Induction assumes some uniformity in nature, or that in some respects the future is like the past [Ayer]
|
|
Full Idea:
In all inductive reasoning we make the assumption that there is a measure of uniformity in nature; or, roughly speaking, that the future will, in the appropriate respects, resemble the past.
|
|
From:
A.J. Ayer (The Problem of Knowledge [1956], 2.viii)
|
|
A reaction:
I would say that nature is 'stable'. Nature changes, so a global assumption of total uniformity is daft. Do we need some global uniformity assumptions, if the induction involved is local? I would say yes. Are all inductions conditional on this?

To say 'I am not thinking' must be false, but it might have been true, so it isn't self-contradictory [Ayer]
|
|
Full Idea:
To say 'I am not thinking' is self-stultifying since if it is said intelligently it must be false: but it is not self-contradictory. The proof that it is not self-contradictory is that it might have been false.
|
|
From:
A.J. Ayer (The Problem of Knowledge [1956], 2.iii)
|
|
A reaction:
If it doesn't imply a contradiction, then it is not a necessary truth, which is what it is normally taken to be. Is 'This is a sentence' necessarily true? It might not have been one, if the rules of English syntax changed recently.

'I know I exist' has no counterevidence, so it may be meaningless [Ayer]
|
|
Full Idea:
If there is no experience at all of finding out that one is not conscious, or that one does not exist, ..it is tempting to say that sentences like 'I exist', 'I am conscious', 'I know that I exist' do not express genuine propositions.
|
|
From:
A.J. Ayer (The Problem of Knowledge [1956], 2.iii)
|
|
A reaction:
This is, of course, an application of the somewhat discredited verification principle, but the fact that strictly speaking the principle has been sort of refuted does not mean that we should not take it seriously, and be influenced by it.

Induction passes from particular facts to other particulars, or to general laws, non-deductively [Ayer]
|
|
Full Idea:
Inductive reasoning covers all cases in which we pass from a particular statement of fact, or set of them, to a factual conclusion which they do not formally entail. The inference may be to a general law, or by analogy to another particular instance.
|
|
From:
A.J. Ayer (The Problem of Knowledge [1956], 2.viii)
|
|
A reaction:
My preferred definition is 'learning from experience' - which I take to be the most rational behaviour you could possibly imagine. I don't think a definition should be couched in terms of 'objects' or 'particulars'.

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'.
