If you don't know what it "is" or what its properties are, 
why are you talking about it? Such talk must be completely 
vacuous.

No, I wouldn't agree. That means absolutely nothing. Sounds 
a bit like Catholic dogma.

Remember, "the only content of knowledge is structure".

What do you do when your dream dies?
Dreams die in every life. But not Pham's 
dream. He had pursued it across five hundred 
light years and three thousand years of 
objective time. It was a dream of a single 
Humankind, where justice would not be 
occasional flickering light, but a steady glow 
across all of Human Space. He dreamed of 
a civilization where continents never 
burned, and where minor kings didn't give 
children away as hostages.
