"And so," Smith said.
"Therefore, it should be obvious that you are not particularly welcome as a member of this class. Surely you have not chosen to remain, and even if you have, it should be obvious that you will not be part of any class of mine until you have successfully passed certain tests, and have been kept under observation. Need I add that after you have taken these tests, we will not be expecting you to remain...."
Several students tittered.
"I'm going to talk now, Garnot of Jlob," Smith said. "You asked me questions earlier. Now I'm going to answer them."
"But I did not...."
"They're questions that should be answered, even though I'm not at all sure that there's enough free-thought here to grasp the real meaning of what I'm going to say."
"I did not tell you to talk."
"I'm Smith of Earth, and this is supposedly a free institution. On Earth I wasn't accustomed to being told when I could talk, when I could listen, when I could think. You asked me once where Earth is. I'll tell you."
"But I do not care and...."
"Earth, interstellarly speaking, is a few parsecs from Sirius. Spaceo-graphically speaking, it isn't very important where it is, not really. Historically, it was at the apex of civilized culture before Jlob ever existed except as a steaming carboniferous swamp peopled largely by a species of amphibian. Socio-psychologically, Earth is a few aeons ahead of the worlds so badly represented here."
