Study vagueness first by its logic, then by its truth-conditions, and then its metaphysics [Fine,K]
|
|
Full Idea:
My investigation of vagueness began with the question 'What is the correct logic of vagueness?', which led to the further question 'What are the correct truth-conditions for a vague language?', which led to questions of meaning and existence.

Kit Fine (Vagueness, Truth and Logic [1975], Intro)
|
|
A reaction:
This is the most perfect embodiment of the strategy of analytical philosophy which I have ever read. It is the strategy invented by Frege in the 'Grundlagen'. Is this still the way to go, or has this pathway slowly sunk into the swamp?

Scientism is the view that everything can be explained causally through scientific method [Critchley]
|
|
Full Idea:
Scientism is the belief that all phenomena can be explained through the methodology of the natural sciences, and the belief that, therefore, all phenomena are capable of a causal explanation.
|
|
From:
Simon Critchley (Interview with Baggini and Stangroom [2001], p.196)
|
|
A reaction:
He links two ideas together, but I tend to subscribe fully to the second idea, but less fully to the first. Scientific method, if there is such a thing (Idea 6804), may not be the best way to lay bare the causal network of reality.

German idealism aimed to find a unifying principle for Kant's various dualisms [Critchley]
|
|
Full Idea:
In his Third Critique Kant established a series of dualisms (pure/practical reason, nature/freedom, epistemology/ethics) but failed to provide a unifying principle; German idealism can be seen as an attempt to provide this principle.
|
|
From:
Simon Critchley (Interview with Baggini and Stangroom [2001], p.187)
|
|
A reaction:
He cites 'subject', 'spirit', 'art', 'will to power', 'praxis' and 'being' as candidates. This is a helpful overview for someone struggling to get to grips with that tradition.

Since Hegel, continental philosophy has been linked with social and historical enquiry. [Critchley]
|
|
Full Idea:
In continental philosophy from Hegel onwards, systematic philosophical questions have to be linked to socio-historical enquiry, and the distinctions between philosophy, history and society begin to fall apart.
|
|
From:
Simon Critchley (Interview with Baggini and Stangroom [2001], p.188)
|
|
A reaction:
I have a strong sales resistance to this view of philosophy, just as I would if it was said about mathematics. It seems to imply a bogus view that history exhibits direction and purpose (the 'Whig' view). There are pure reasons among the prejudices.

Continental philosophy has a bad tendency to offer 'one big thing' to explain everything [Critchley]
|
|
Full Idea:
In continental philosophy there is a pernicious tendency to explain everything in terms of 'one big thing', such as the 'death drive' (Freud), 'being' (Heidegger), 'the real' (Lacan), 'power' (Foucault), 'the other' (Levinas), or 'différance' (Derrida).
|
|
From:
Simon Critchley (Interview with Baggini and Stangroom [2001], p.197)
|
|
A reaction:
From a fan of this type of philosophy, this is a refreshing remark, because if pinpoints a very off-putting feature. Each of these 'big things' should be up for question, not offered as axiomatic assumptions that explain everything else.

Excluded Middle, and classical logic, may fail for vague predicates [Fine,K]
|
|
Full Idea:
Maybe classical logic fails for vagueness in Excluded Middle. If 'H bald ∨ ¬(H bald)' is true, then one disjunct is true. But if the second is true the first is false, and the sentence is either true or false, contrary to the borderline assumption.
|
|
From:
Kit Fine (Vagueness, Truth and Logic [1975], 4)
|
|
A reaction:
Fine goes on to argue against the implication that we need a special logic for vague predicates.

Vagueness is semantic, a deficiency of meaning [Fine,K]
|
|
Full Idea:
I take vagueness to be a semantic feature, a deficiency of meaning. It is to be distinguished from generality, undecidability, and ambiguity.
|
|
From:
Kit Fine (Vagueness, Truth and Logic [1975], Intro)
|
|
A reaction:
Sounds good. If we cut nature at the joints with our language, then nature is going to be too subtle and vast for our finite and gerrymandered language, and so it will break down in tricky situations. But maybe epistemology precedes semantics?

A thing might be vaguely vague, giving us higher-order vagueness [Fine,K]
|
|
Full Idea:
There is a possibility of 'higher-order vagueness'. The vague may be vague, or vaguely vague, and so on. If J has few hairs on his head than H, then he may be a borderline case of a borderline case.
|
|
From:
Kit Fine (Vagueness, Truth and Logic [1975], 5)
|
|
A reaction:
Such slim grey areas can also be characterised as those where you think he is definitely bald, but I am not so sure.

Logical connectives cease to be truth-functional if vagueness is treated with three values [Fine,K]
|
|
Full Idea:
With a three-value approach, if P is 'blob is pink' and R is 'blob is red', then P&P is indefinite, but P&R is false, and P∨P is indefinite, but P∨R is true. This means the connectives & and ∨ are not truth-functional.
|
|
From:
Kit Fine (Vagueness, Truth and Logic [1975], 1)
|
|
A reaction:
The point is that there could then be no logic in any way classical for vague sentences and three truth values. A powerful point.
|
|

|
With the super-truth approach, the classical connectives continue to work [Fine,K]
|
|
Full Idea:
With the super-truth approach, if P is 'blob is pink' and R is 'blob is red', then P&R is false, and P∨R is true, since one of P and R is true and one is false in any complete and admissible specification. It encompasses all 'penumbral truths'.
|
|
From:
Kit Fine (Vagueness, Truth and Logic [1975], 3)
|
|
A reaction:
[See Idea 9767 for the super-truth approach, and Idea 9770 for a contrasting view] The approach, which seems quite appealing, is that we will in no circumstances give up basic classical logic, but we will make maximum concessions to vagueness.

Perceiving meaninglessness is an achievement, which can transform daily life [Critchley]
|
|
Full Idea:
If nihilism is the threat of the collapse of meaning, then my position is that one has to accept meaninglessness as an achievement, as an accomplishment that permits a transformed relation to everyday life.
|
|
From:
Simon Critchley (Interview with Baggini and Stangroom [2001], p.193)
|
|
A reaction:
This sounds cheerfully upbeat and life-enhancing, but I don't quite see how it works. One could easily end up laughing at the most appalling tragedies, and that seems to me to be an inappropriate (Aristotelian word) way to respond to tragedy.
