| What's so special about "humanity" that it needs to be preserved? The frustrating thing about your nihilistic argument is that there's no practical way we can divide humanity into the grasshoppers who live only for today and the ants who live for the future. A consequence of the advance of democracy -- itself arguably a prerequisite for survival -- is that the grasshoppers will always be with us, and will always have a voice. If there were a way we could magically reserve the benefits and spinoffs of human space exploration, up to and including the potential preservation of the species, to those who agreed to pay for them, I'd be much more accepting of this kind of question. But colonization of other celestial bodies is too big a job for only part of humanity to tackle. We all need to pull in that direction, or we'll fail. So the fundamental problem becomes one of how to convince people of all walks of life that this is a worthwhile goal that can, and should, be achieved. It's a tough sell -- like the great European cathedrals, it will take longer than any one lifetime, and cost more than any one king can afford. But it seems possible to make sound, rational arguments in favor of such a mission. There are times when I almost believe that the necessary case can be made, and that the necessary work will be done... ... at least until some overly-clever bozo asks an unanswerable question like, "What's so special about humanity that it needs to be preserved?" Then, I sink back into my usual unproductive attitude: "Fine. Screw you. Stay behind, see if we care." And sure enough, as usual, nothing changes. |
