"Oh,yes,"said Dr. Phineas Welch, "I can bring back the spirits of the illustrious dead."
He was a little drunk, or maybe he wouldn't have said it. Of
course, it was perfectly all right to get a little drunk at the annual
Christmas party.
Scott Robertson, the school's young English instructor, adjusted
his glasses and looked to right and left to see if they were overheard.
"Really, Dr. Welch."
"I mean it. And not just the spirits. I bring back the bodies, too."
"I wouldn't have said it were possible," said Robertson primly.
"Why not? A simple matter of temporal transference."
"You mean time travel? But that's quite - uh - unusual."
"Not if you know how."
"Well, how, Dr. Welch?"
"Think I'm going to tell you?" asked the physicist gravely. He
looked vaguely about for another drink and didn't find any. He said, "I
brought quite a few back. Archimedes, Newton, Galileo. Poor fellows."
"Didn't they like it here? I should think they'd have been
fascinated by our modern science," said Robertson. He was beginning to
enjoy the conversation.
"Oh, they were. They were. Especially Archimedes. I thought he'd
go mad with joy at first after I explained a little of it in some Greek
I'd boned up on, but no-no-"
"What was wrong?"
"Just a different culture. They couldn't get used to our way of
life. They got terribly lonely and frightened. I had to send them back."
"That's too bad."
"Yes. Great minds, but not flexible minds. Not universal. So I tried Shakespeare."
"What?" yelled Robertson. This was getting closer to home.
