Deconstructing philosophy gives the history of concepts, and the repressions behind them [Derrida]
|
|
Full Idea:
To 'deconstruct' philosophy would be to think the structured genealogy of philosophy's concepts, but at the same time determine what this history has been able to dissimulate or forbid, making itself into history by this motivated repression.
|
|
From:
Jacques Derrida (Implications [1967], p.5)
|
|
A reaction:
All of this type of philosophy is motivated by what I think of as (I'm afraid!) a rather adolescent belief that we are all being 'repressed', and that somehow, if we think hard enough, we can all become 'free', and then everything will be fine.

The movement of 'différance' is the root of all the oppositional concepts in our language [Derrida]
|
|
Full Idea:
The movement of 'différance', as that which produces different things, that which differentiates, is the common root of all the oppositional concepts that mark our language, such as sensible/intelligible, intuition/signification, nature/culture etc.
|
|
From:
Jacques Derrida (Implications [1967], p.7)
|
|
A reaction:
'Différance' is a word coined by Derrida, and his most famous concept. At first glance, the concept of a thing which is the source of all differentiation sounds like a fiction.

Classical logic is bivalent, has excluded middle, and only quantifies over existent objects [Jacquette]
|
|
Full Idea:
Classical logic (of Whitehead, Russell, Gödel, Church) is a two-valued system of propositional and predicate logic, in which all propositions are exclusively true or false, and quantification and predication are over existent objects only.
|
|
From:
Dale Jacquette (Intro to I: Classical Logic [2002], p.9)
|
|
A reaction:
All of these get challenged at some point, though the existence requirement is the one I find dubious.
