Science fiction writers can deploy extraterrestrials to the same effect. A classic example is Wellsian Selenites. When violence between human beings results in a death, a grotesque-looking alien imagined by Poul Anderson responds thus:
"A gruesome keening lifted from the Naqsan. 'Gwurru shka ektrush, is this war? We do not thus at home. Rahata, rahata.'"
-Poul Anderson, The Star Fox (London, 1968), p. 101.
If a Naqsan can ask this, then we must ask why we do thus, especially since, in this case, the killer is a "Militant for Peace."
Endre Vadasz, another wandering space minstrel, sings the Paternoster (Our Father, Lord's Prayer) over a grave. Respectful treatment of the dead is yet another theme in Anderson's works.
