Jean-Pierre Dupuy Libri

An examination of the fundamental role cybernetics played in the birth of cognitive science and the light this sheds on current controversies.

Originally published in French under the title La marque du sacre.

The possibility of a nuclear war that could destroy civilization has influenced the course of international affairs since 1945, suspended like a sword of Damocles above the heads of the world's leaders. The fact that we have escaped a third world war involving strategic nuclear weapons--indeed, that no atomic weapon of limited power has yet been used under battlefield conditions--seems nothing short of a miracle. Revisiting debates on the effectiveness and ethics of nuclear deterrence, Jean-Pierre Dupuy is led to reformulate some of the most difficult questions in philosophy. He develops a counterintuitive but powerful theory of apocalyptic prophecy: once a major catastrophe appears to be possible, one must assume that it will in fact occur. Dupuy shows that the contradictions and paradoxes riddling discussions of deterrence arise from the tension between two opposite conceptions of time: one in which the future depends on decisions and strategy, and another in which every occurring event is one that could not have failed to occur. Considering the immense destructive power of nuclear warheads and the almost unimaginable destruction they are bound to cause, Dupuy reaches a provocative conclusion: whether they bring about good or evil does not depend on the present or future intentions of those who are in a position to use them. The mere possession of nuclear weapons is a moral abomination.
