"...those old boring diaries we read in English class were time capsules, preserving the writers' patterns of thought."
"Unlike computers, we're not bound to count each second correctly. We're at liberty to accord each moment its proper weight, depending on its meaning to us."
Read this along with Gene Wolfe's A BORROWED MAN and Alena Graedon's THE WORD EXCHANGE. All 3 were recommended through the library's readers advisory service. None were were quite what I had hoped but each was readable in its own way.
