C.S. Lewis's essay is and will be always a good guide. And thank you Pauline for the interesting thoughts which I share. The realm of possibility should not be considered void of reality. One often hides in the other and vice versa.

Jules Verne was quoted as saying, "it will all come true..." and it has always struck me that the maxim of "it is impossible for the human brain to imagine anything that is not possible, therefore everything imagined is or will become reality..." are the rules by which sci-fi is governed and, by and large, abides. The time-lag is also interesting. Heinline's "Waldos" are the backbone of industry, as are his ubiquitous video glasses "posting" to an intra-net - both written in the '50s. My most recent sci-fi epistle got this comment "...has its own laws of stretching brains wide with its mind-bending concepts." And so I sit here wondering if I will be right, and if so, when?
