 How does the phrase "to be or not to be" tie into the overall story?
A Gleeb for Earth By CHARLES SHAFHAUSER Illustrated by EMSH [Transcriber's Note: This etext was produced from Galaxy Science Fiction May 1953. Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Not to be or not to not be ... that was the not-question for the invader of the not-world. I had to get in touch with somebody about this because if there is something to it, then somebody, everybody, is going to point finger at me, Ivan Smernda, and say, "Why didn't you warn us?" I run a strictly legit hotel even though some of my guests might be down on their luck now and then. All this was buttoned up like Binkle had melted out of it and dripped through a crack in the floor. India, China, England, everywhere. Now you have them. Hold firm in your wretched projection, for tomorrow you will not be alone in the not-world. I have attuned myself to a fetus within the body of a not-woman in the not-world. Already I am static and for hours have looked into this weird extension of the Universe with fear and trepidation. My wave went out to yours and found it, barely pulsing and surrounded with an impregnable chimera. So I must communicate with you by what the not-world calls "mail" till we meet. I, Glmpauszn, come equipped with powers evolved from your fragmentary reports before you ceased to vibrate to us and with a vast treasury of facts from indirect sources. Soon our tortured people will be free of the fearsome not-folk and I will be their liberator. He does not know he writes it. You must never know of my exact location, for the not-people might have access to the information. I must leave off now because the not-child is about to be born. When it is alone in the room, it will be spirited away and I will spring from the pod on the gateway into its crib and will be its exact vibrational likeness. But the not-people must never know I am among them. This is the only way I could arrive in the room where the gateway lies without arousing suspicion. I will grow up as the not-child in order that I might destroy the not-people completely. All is well, only they shot this information file into my matrix too fast.
 It plays into the nature of Glmpauszn's people, and how they exist along side ours.
 It is what Glmpauszn has to ask himself as he invades the not-world.  It plays into the nature of Glmpauszn's people, and how they exist along side ours.  It references Glmpauszn's disappearance, and the question if he was ever really there.  It plays into the uncertain nature of the story's truth.
