For context, this is the paragraph: I come at last to death and to the attitude we have toward it. On this point everything has been said and it is only proper to avoid pathos. Yet one will never be sufficiently surprised that everyone lives as if no one "knew." This is because in reality there is no experience of death. Properly speaking, nothing has been experienced but what has been lived and made conscious. Here, it is barely possible to speak of the experience of others' deaths.
It is a substitute, an illusion, and it never quite convinces Us. ***That melancholy convention cannot be persuasive.*** The horror comes in reality from the mathematical aspect of the event. If time frightens us, this is because it works out the problem and the solution comes afterward. All the pretty speeches about the soul will have their contrary convincingly proved, at least for a time. From this inert body on which a slap makes no mark the soul has disappeared. This elementary and definitive aspect of the adventure constitutes the absurd feeling. Under the fatal lighting of that destiny, its uselessness becomes evident. No code of ethics and no effort are justiable a prior in the face of the crue mathematics that command our
condition.
