Anderson has written extensively about the moon, from the scientific realism of "Escape the Morning" to the ethereal world of the lunarians in Harvest of Stars. He also has a longstanding interest in how people would respond to the stresses of living on worlds other than earth. Eleven of these have been gathered in Space Folk, including "Escape the Morning" (which originally appeared in Boys' Life). In general, Anderson's view is positive; people usually overcome the dangers they face, as do the characters in "Escape the Morning." Even so, occasionally, as in "Murphy's Hall" (1971), events can go terribly wrong, showing that Anderson's view allows for the realities of disasters and failures as people try to populate alien places.
