In any case, revisiting Earth, Mars, Mercury and Titan in this novel, as is usual with Vonnegut, combined the pleasure of cavorting around in his playground of ideas and jokes and purring with pleasure at his style:
And yawning under all those bowls was the upturned mouth of the biggest bowl of them all...a regular Beelzebub of a bowl, bone dry and insatiable...waiting, waiting, waiting for that first sweet drop.
with the renewed realisation that very few books were going to produce such a rich reading experience. I'm grateful for Vonnegut's having been relatively prolific, and thus leaving scope for a long and varied cycle of re-reading.
As do many of his books, Sirens features a fabricated religion, The Church of God the Utterly Indifferent, whose central credo is that we are all the 'victims of a series of accidents' and which vehemently denies the existence of any benevolent divine working in the universe. For Vonnegut, fictitious religion was a tautology, and his repeated coinings of faiths, such as The Church of Jesus Christ the Kidnapped and Bokononism, embody this view. The latter is Vonnegut's most involved and detailed religious system and, typically, has at its first statement that what follows is a highly systematic series of untruths. Although these created theologies have specific satirical and structural roles in the various books, they are of course reiterating Vonnegut's belief that all religion is a fiction but that it's important to choose the most effective one nonetheless. This stance is related to his also oft-repeated observation that we all depend on constructing narratives - which may have serious arguments with reality - to maintain our mental stability. The writer of this blog does not necessarily endorse either of these views, although he is (as you may have gathered) capable of being infinitely charmed by Vonnegut's various expressions of them.
It is interesting to note that, among the many cultural references inspired by Vonnegut, Bokononism (which is an integral part of the novel Cat's Cradle) features fairly heavily, although the best-known homage is probably Al Stewart's song, The Sirens of Titan, which very elegantly converts the novel into a modern popular beat composition.
So it goes.
