Jacques Derrida · Philosophy
In his later years Derrida turned to ethics and politics, surprising those who thought deconstruction was a nihilist game. He argued that justice itself is <em>undeconstructible</em> - the very thing in whose name we deconstruct unjust laws - and developed a series of ‘impossible’ ideas: pure hospitality, the gift, forgiveness, and a democracy always still ‘to come.’
For decades critics charged that deconstruction was ethically and politically bankrupt - a clever game of unraveling texts that could give no account of right and wrong, justice and injustice, and that, by dissolving all foundations, left us with nothing to stand on. In the late 1980s and 1990s Derrida answered this charge head-on, turning explicitly to ethics, law, and politics. The pivotal text was a 1989 lecture, later published as Force of Law, delivered to a conference of legal scholars. There Derrida made a startling claim that overturned the whole picture of deconstruction as nihilism: ‘Deconstruction is justice.’ Far from dissolving justice, he argued, deconstruction is the very movement of justice at work.
The key was a distinction between two things usually run together: law (in French, droit - positive law, statutes, legal systems) and justice. Law, Derrida argued, is constructed: it is made by human beings, written down, enforced, historically variable, full of compromises and exclusions. Because it is constructed, it can be deconstructed - analyzed, criticized, shown to rest on contestable choices and to harbour injustices, and therefore changed. Justice, by contrast, is undeconstructible. It is not a body of rules we possess but an infinite demand, never fully captured by any law, in whose name we judge laws to be just or unjust and push to reform them. Deconstruction operates exactly in the gap between the two: it deconstructs the always-imperfect law in the name of the justice that no law can ever fully embody.
Why call justice undeconstructible and even ‘impossible’? Because, Derrida argued, a genuinely just decision can never be merely the mechanical application of a rule. If justice were just following the rules, a computer could dispense it, and there would be no responsibility and no judgment involved at all - just calculation. But every real case is singular: this person, this situation, in all its irreducible particularity. To do justice, the judge must apply the general rule and respond to the singular case the rule cannot fully anticipate - must, in a sense, reinvent the law afresh for this case. Derrida says a just decision must pass through an ‘ordeal of the undecidable’: a moment where the rule does not simply dictate the answer, where the decider must actually decide, taking responsibility rather than hiding behind the rule. A decision that merely follows the rule is not, strictly, a decision at all.
This is why justice is ‘impossible’ in Derrida’s special sense - not unreal or unattainable in a way that breeds despair, but exceeding every possible calculation, never fully achieved in any actual law or verdict. Justice is infinite, owed to the singular other, irreducible to any general formula; law is finite, general, calculable. The two need each other: justice without law is empty (it must be enacted in actual rules and institutions), and law without justice is blind (mere force dressed as legality). The just person lives in the tension between them - applying rules, yes, but never letting the rule extinguish responsiveness to the singular case and the infinite demand of the other. The undeconstructibility of justice is precisely this excess of the demand over every rule we devise to meet it.
The ethical turn reframes everything that came before. If you thought deconstruction meant ‘nothing is really true or right, so anything goes,’ the late Derrida shows you were misreading it from the start. Deconstruction unsettles foundations, yes - but it does so, he now makes explicit, in the name of something it does not unsettle: the undeconstructible demand of justice, of responsibility to the other. The whole point of showing that a law, an institution, a hierarchy is constructed and contingent is to open it to change - to expose its exclusions so they can be contested, in the name of those it has wronged. Deconstruction is motivated, all the way down, by a responsiveness to what existing structures leave out, silence, or oppress. It is, in this sense, an intensely ethical practice: a refusal to let any human arrangement pass itself off as natural, final, and beyond question, because to do so would be to betray those it excludes.
This is why Derrida could say that deconstruction is ‘hyper-ethical’ rather than anti-ethical. Far from licensing indifference, it demands a heightened vigilance: an unwillingness to rest in any settled answer, a constant attention to the singular other the rule does not fit, a suspicion of every claim to have finally achieved justice. The deconstructor is not the cynic who believes in nothing but the restless conscience who believes the demand of justice is never satisfied. In his last decades Derrida applied this to the most concrete questions - immigration and the treatment of refugees, the death penalty, forgiveness after atrocity, animal suffering, the future of democracy and Europe - showing that deconstruction, properly understood, is not a retreat from the world into wordplay but a way of keeping our hardest ethical and political questions open, urgent, and unfinished.
This is the opening of the lesson. The rest — the dialogue, the primary source, and the recall — is in the app.
You learned that the later Derrida drew a sharp line between law (droit) - which is constructed, calculable, and always deconstructible - and justice , which is undeconstructible: the infinite demand in whose name unjust laws are criticized and reformed. You also met his ‘impossible’ concepts: pure hospitality, the gi…
