My favorite part:

"Suppose you're in a boat, sailing down a winding stream. You watch the banks as they pass you. You went by a grove of maple trees upstream, but you can't see them now so you saw them in the past. Didn't you? Now you're watching a field of clovers before your eyes in this moment; in the present. But you don't know what's waiting for you around the bend in the stream ahead. It may be wonderful things but you can't see them until you get around the bend in the future. Can you? All right now, remember, you're in the boat, but I'm in the sky above you in a plane. I'm looking down on it all. I can see it all at once. So the past, the present and the future of the man in the boat are all one to the man in the plane. But doesn't that prove that all time must really be one? Time, real time, is nothing but an idea, in the mind of god."

Entertaining how he could never fit into the late 18th Century era he went back to, and how everyone there easily saw how out of place he was. I never quite got the mechanism of time travel and how he controlled it, but it was a sweet story with a sad ending.
