The book ended up with a pretty fun collection of epigraphs for each chapter. But there are a lot more good quotes about time than chapters in the book. Here are some of the quotes I did not end up using. Further examples are hereby solicited -- who knows when they might turn out to be useful?
"Everything happens to everybody sooner or later if there is time enough." -- George Bernard Shaw, Back to Methuselah "Time is the longest distance between two places." -- Tennessee Williams, The Glass Menagerie "The future's not ours to see." -- Doris Day "Time rushes toward us with its hospital tray of infinitely varied narcotics, even while it is preparing us for its inevitably fatal operation." -- Tennessee Williams, The Rose Tattoo "Time, you old gypsy man, Will you not stay, Put up your caravan Just for one day?" -- Ralph Hodgeson "Time present and time past Are both perhaps present in time future, And time future contained in time past. If all time is eternally present All time is unredeemable." -- T.S. Eliot, "Burnt Norton" (Four Quartets) "Time is the substance from which I am made. Time is a river that carries me along, but I am the river; it is a tiger that devours me, but I am the tiger; it is a fire that consumes me, but I am the fire." -- Jorge Luis Borges, Labyrinths.
Apparently you have to be extremely careful when it comes to poetry; fair use doesn't necessarily extend very far.
