A Parable on Prejudice
When Smith, of Earth, comes to a renowned galactic school, he immediately finds himself the laughingstock of everyone else, with the possible exception of Geria, of Bortinot, because in these latter days when the sun is a big red, bloated star the Earth, although actually the starting point of all interplanetary colonialism, and therefore the cradle of every other civilization, is now regarded as some kind of hillbilly backwater hardly worth mentioning. Smith is made fun of because of his outward appearance, his alleged lack of knowledge and his inability to use psi-powers. Only Geria takes some genuine human interest in him, but even she tends to look down on him – but eventually, Smith will put both his foot down and everyone else into their right place and decide that he does not want to be part of a civilization that is egocentric in its core and also decadent in its admiration of qualities that have long been discarded as harmful on Earth.
The message of the short story Earthsmith by Milton Lesser is quite obvious, but despite its laudability, it is marred by a love story that does not really make a whole lot of sense and by a dénouement that is far too optimistic in the light of all the suffering the victims of discrimination and racism have to undergo: Smith can go back to Earth, knowing that it is not worth his while to be part of a society that looks down on him and his fellow-Terrans, but in many ways, this is neither possible nor desirable with regard to people who are discriminated against in our present-day world because modern societies are based on diversity and a withdrawal of certain groups, ethnic, religious or gender-defined, must be seen as a defeat of reason and humanity.
All in all, this makes Earthsmith a rather dissatisfying and puerile story.
