"The value of [this story] lies in the human look upon us, a look which tried to reach down into the spirit and thereby, maychance, now opens for us a glimpse into theirs." (p. 25)
This is the concluding paragraph of Hloch's Introduction to "The Problem of Pain." Thus, in the Earth Book Of Stormgate, not only do Ythrians look at human beings as a species but also, more specifically, they look into one human being who had tried to look deeply into the Ythrians and who thus possibly disclosed more of humanity to them!
Just as "nation" is an alien idea to an Ythrian, a Christian from the colony planet, Aeneas, finds the Ythrian New Faith difficult to square with his beliefs.
