Why 300 years? Because it lifts our sights beyond those with whom we are able to talk. Because those in 300 years are close enough we can imagine them, but far enough away we are forced to think longer, in terms of lineages and species. Because we need to raise our sights beyond the quick fix. Because we are forced to ask what is best for humanity and maybe even life itself. Because it requires us to ask, How does what I do and who I am today have effects beyond me? Can we improve humanity, just a little?
