I humbly apologize for summarizing out of turn.
There is, in Germanic tradition, a "Gõtterdammerung" perspective that this seems somewhat akin to, though I may be giving it more credit than it has coming. I mean that there is a Nordic tendency toward a view of life as bleak and "we're doomed so we'll live it to the fullest"; which is, essentially, a form of "eat drink and be merry for tomorrow we die". So it seems akin, but perhaps gives these frankly cowardly literati too much credit, if I may make so bold in calling them so.
