This story by Pejman Yousefzadeh made me think of an aphorism. Any society that requires a fundamental change in human nature is doomed. It seems like any time a social experiment fails the creators of the experiment blame the participants for a failure to change or adapt.
Yet these experiments continue to be tried. If an inventor were to blame gravity for the persistent failure of his space ships, he would be written off as a crank. Why does the same not happen to utopians?
