deconstruction n. not what you think: the experience of the impossible: what remains to be thought: a logic of destabilization always already on the move in ‘things themselves’: what makes every identity at once itself and different from itself: a logic of spectrality: a theoretical and practical parasitism or virology: what is happening today in what is called society, politics, diplomacy, economics, historical reality, and so on: the opening of the future itself.

When you are criticizing the philosophy of an epoch, do not chiefly direct your attention to those intellectual positions which its exponents feel it necessary explicitly to defend. There will be some fundamental assumptions which adherents of all the variant systems within the epoch unconsciously presuppose. Such assumptions appear so obvious that people do not know what they are assuming because no other way of putting things has ever occurred to them. With these assumptions a certain limited number of types of philosophical systems are possible, and this group of systems constitutes the philosophy of the epoch.
