Upon Reflection, However,

I perceive that it's not Alpha Centaureans who are determined that Earthlings not know of their existence--but our own "Security Agencies," who stand to lose all their power of secrecy,  violence and terror if the mere rumor or suspicion of a Galactic Civilization were to transpire.  And sure, the way the Hubble was "eliminated" bespeaks the hasty, atrociously clever "smart assness" of the CIA /FBI/NSA rather than the policy of a billion year old civilization. 

Reading now Postmodern Pooh--alternating between it and the dead-seriousness of George Perle's Operas of Alban Berg--I do indeed see a world at an end; a silly, ignominious, deliberately stupid, and a fatally, fatuously vainglorious little end.  In all of Postmodernism there is not a jot or a tittle of modesty, honesty, decency, or simplicity.  It is utterly and entirely a matter of fakery, ostentation, cowardice, and villainy.  With the single exception, perhaps, of Jean Baudrillard.
