I Am Crying All Inside

“To read science fiction is to read Simak. A reader who does not like Simak stories does not like science fiction at all.” —Robert A. Heinlein
 
“Like Olaf Stapledon and SF’s later mystics, Simak could dream on a grand scale. . . . Thoreau or Wordsworth would feel at home in his isolated houses rooted in natural landscapes.” —Locus
 
“Simak is the most underrated great science fiction writer alive, and has never written a bad book.” —Theodore Sturgeon
 
“I read [Simak’s] stories with particular attention, and I couldn’t help but notice the simplicity and directness of the writing—the utter clarity of it. I made up my mind to imitate it, and I labored over the years to make my writing simpler, clearer, more uncluttered, to present my scenes on a bare stage.” —Isaac Asimov
 
“Without Simak, science fiction would have been without its most humane element, its most humane spokesman for the wisdom of the ordinary person and the value of life lived close to the land.” —James Gunn
