SCIENCE AND FICTION TIME MACHINE TALES - PAUL...

This book contains a broad overview of time travel in science fiction  along with a detailed
examination of the philosophical implications of time travel. The emphasis of this book is now
on the philosophical and on science fiction  rather than on physics  as in the author's earlier
books on the subject. In that spirit there are  for example  no Tech Notes filled with algebra
integrals  and differential equations  as there are in the first and second editions of TIME
MACHINES. Writing about time travel is  today  a respectable business. It hasn't always been
so. After all  time travel  prima facie  appears to violate a fundamental law of nature  every
effect has a cause  with the cause occurring before the effect. Time travel to the past 
however  seems to allow  indeed to demand  backwards causation  with an effect (the time
traveler emerging into the past as he exits from his time machine) occurring before its cause
(the time traveler pushing the start button on his machine's control panel to start his trip
backward through time). Time Machine Tales includes new discussions of the advances by
physicists and philosophers that have appeared since the publication of TIME MACHINES in 1999 
examples of which are the chapters on time travel paradoxes. Those chapters have been brought
up-to-date with the latest philosophical thinking on the paradoxes.
