If 'red' is vague, then membership of the set of red things is vague, so there is no set of red things [Sainsbury]
|
|
Full Idea:
Sets have sharp boundaries, or are sharp objects; an object either definitely belongs to a set, or it does not. But 'red' is vague; there objects which are neither definitely red nor definitely not red. Hence there is no set of red things.

|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §2)
|
|
A reaction:
Presumably that will entail that there IS a set of things which can be described as 'definitely red'. If we describe something as 'definitely having a hint of red about it', will that put it in a set? In fact will the applicability of 'definitely' do?

We should abandon classifying by pigeon-holes, and classify around paradigms [Sainsbury]
|
|
Full Idea:
We must reject the classical picture of classification by pigeon-holes, and think in other terms: classifying can be, and often is, clustering round paradigms.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §8)
|
|
A reaction:
His conclusion to a discussion of the problem of vagueness, where it is identified with concepts which have no boundaries. Pigeon-holes are a nice exemplar of the Enlightenment desire to get everything right. I prefer Aristotle's categories, Idea 3311.

If concepts are vague, people avoid boundaries, can't spot them, and don't want them [Sainsbury]
|
|
Full Idea:
Vague concepts are boundaryless, ...and the manifestations are an unwillingness to draw any such boundaries, the impossibility of identifying such boundaries, and needlessness and even disutility of such boundaries.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §5)
|
|
A reaction:
People have a very fine-tuned notion of whether the sharp boundary of a concept is worth discussing. The interesting exception are legal people, who are often forced to find precision where everyone else hates it. Who deserves to inherit the big house?

Boundaryless concepts tend to come in pairs, such as child/adult, hot/cold [Sainsbury]
|
|
Full Idea:
Boundaryless concepts tend to come in systems of contraries: opposed pairs like child/adult, hot/cold, weak/strong, true/false, and complex systems of colour terms. ..Only a contrast with 'adult' will show what 'child' excludes.
|
|
From:
Mark Sainsbury (Concepts without Boundaries [1990], §5)
|
|
A reaction:
This might be expected. It all comes down to the sorites problem, of when one thing turns into something else. If it won't merge into another category, then presumably the isolated concept stays applicable (until reality terminates it? End of sheep..).

The Eightfold Path concerns morality, wisdom, and tranquillity [Ashvaghosha]
|
|
Full Idea:
The Eightfold Path has three steps concerning morality - right speech, right bodily action, and right livelihood; three of wisdom - right views, right intentions, and right effort; and two of tranquillity - right mindfulness and right concentration.
|
|
From:
Ashvaghosha (Saundaranandakavya [c.50], XVI)
|
|
A reaction:
Most of this translates quite comfortably into the aspirations of western philosophy. For example, 'right effort' sounds like Kant's claim that only a good will is truly good (Idea 3710). The Buddhist division is interesting for action theory.

At the end of a saint, he is not located in space, but just ceases to be disturbed [Ashvaghosha]
|
|
Full Idea:
When an accomplished saint comes to the end, he does not go anywhere down in the earth or up in the sky, nor into any of the directions of space, but because his defilements have become extinct he simply ceases to be disturbed.
|
|
From:
Ashvaghosha (Saundaranandakavya [c.50], XVI)
|
|
A reaction:
To 'cease to be disturbed' is the most attractive account of heaven I have encountered. It all sounds a bit dull though. I wonder, as usual, how they know all this stuff.
