6.4312 The temporal immortality of the soul of man, meaning therefore its eternal survival even after death, is not only in no way guaranteed, but in the first place this assumption does not at all do what people have always wanted to achieve with it. Is a riddle thereby solved, because I survive eternally? Is eternal life, on this account, then not just as mysterious as the present one? The solving of the riddle of life in space and time lies outside of space and time.

(It is indeed not problems of natural science that are to be solved.)

Ah, but is the solution to this riddle found in the disappearance of the riddle? See CV, p. 27 (1937), and p. 74 and p. 75. Is there a riddle really? Or is the experience of life as a riddle more like an unpleasant feeling in response to awareness of the mystery of life. And that awareness itself might not seem to be anything (awareness of anything) if we think it through. “Mystery” might perhaps be better than “riddle” here. Wittgenstein, in Letters to Ogden, p. 36, says: “I don’t wish that there should be anything ridiculous or profane or frivolous in the word when used in the connection “riddle of life” etc.”
