Deconstruction is not neutral; it intervenes [Derrida]
|
|
Full Idea:
Deconstruction, I have insisted, is not neutral. It intervenes.
|
|
From:
Jacques Derrida (Positions [1971], p.76)
|
|
A reaction:
This, I think, is because there is in Derrida, as in most French philosophers, a strong streak of Marxism, and a desire to change the world, rather than merely understanding it. Idea 8213 shows the sort of thing he wants to change.

I try to analyse certain verbal concepts which block and confuse the dialectical process [Derrida]
|
|
Full Idea:
I have tried to analyse certain marks in writing which are undecidables, false verbal properties, which inhabit philosophical opposition, resisting and disorganising it, without ever constituting a third term, withour ever leaving room for a solution.
|
|
From:
Jacques Derrida (Positions [1971], p.40)
|
|
A reaction:
[I have simplified his sentence!] Much of Derrida seems to be a commentary on the Hegelian dialectic, and the project is presumably to figure out why philosophy is not advancing in the way we would like. Interesting...

Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? [Edgington]
|
|
Full Idea:
Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? Are they non-truth-functional, like 'because' or 'before'? Do the values of A and B, in some cases, leave open the value of 'If A,B'?
|
|
From:
Dorothy Edgington (Conditionals [2001], 17.1)
|
|
A reaction:
I would say they are not truth-functional, because the 'if' asserts some further dependency relation that goes beyond the truth or falsity of A and B. Logical ifs, causal ifs, psychological ifs... The material conditional ⊃ is truth-functional.

'If A,B' must entail ¬(A & ¬B); otherwise we could have A true, B false, and If A,B true, invalidating modus ponens [Edgington]
|
|
Full Idea:
If it were possible to have A true, B false, and If A,B true, it would be unsafe to infer B from A and If A,B: modus ponens would thus be invalid. Hence 'If A,B' must entail ¬(A & ¬B).
|
|
From:
Dorothy Edgington (Conditionals [2001], 17.1)
|
|
A reaction:
This is a firm defence of part of the truth-functional view of conditionals, and seems unassailable. The other parts of the truth table are open to question, though, if A is false, or they are both true.
