question:  Why is Wyandotte didactic?
context: Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed.] Rootless and footloose, a man in space can't help but dream of coming home. He was uncomfortable; Wyandotte seemed to know all about him. "Oh, I've landed a few times, even walked around for a while...." Short of Gravitational conditioning, there is nothing to stop you from going to Terra." It helps suppress certain physiological reactions to an entirely new set of conditions. They play an important part in our awareness of balance. Returning to gravity is rather frightening at first." "You've undoubtedly read popularizations in tapezines. "Do you know what sailors of ancient times meant by 'sea legs?'" asked Wyandotte. During the days that followed, the psychologist seemed to Craig to become progressively more didactic. He spoke repetitiously of the "growing complexity of Terran society." They were incredibly varied, even those that supported life. He had been on Einstein IV, the planet of eight moons, and had felt the pulse of all eight of the satellites at once that no PON could completely nullify. But even if he could accept the psychologist's authority for the cumulative effect of a gravity system, he could not understand the unspoken warning he felt underlying all that the man said. "Yet you are so completely sure you will want to live out your life there, that you are willing to give up space service for it." You will be given a very liberal supply of PON—which you will definitely need. On the eighth day, two attendants, who showed the effects of massive doses of PON to protect themselves from the centrifugal force, had to carry a man out of the tank. Many others asked to be removed, begged to be allowed to withdraw their resignations. "The twelfth day is the worst," a grizzled spaceman told Craig. "How ... how do they know when you ought ... to come out?" "Can't they ... drop it down continuously?"
output:  He thinks Craig will be a fish out of water in Terran society.
options:  He is likely being monitored by the Terrans and cannot speak freely.  He thinks Craig is an uneducated hick.  He knows that gravity conditioning is horrible. He is trying to change Craig's mind about going to Terra.  He thinks Craig will be a fish out of water in Terran society.
