"When is it okay to violate Star Fleet's Prime Directive? Is it cheating to be a telepathic psychiatrist? Is it possible to occupy someone else's body?" "Wouldn't it be great fun to look back at the carefully crafted philosophical constraints that guide all Federation behavior, except this time do so through the eyes of a trained philosopher?" "Filled with examples from all the best episodes, this book is for anyone who has ever found himself replaying, alone or with a fellow Trekker, an episode's philosophical challenges - for instance, whether or not Data is sentient (if so, what about Lore?); whether Captain Picard violated the Prime Directive to save the life of Wesley Crusher; or whether or not Tuvix had a right to live even if it meant the end of Tuvok and Neelix." "Among the reasons the shows have such loyal followers is the complexity of the moral dilemmas within which the captain and crew of the Enterprise, Voyager, and Deep Space Nine must fit their behavior. Also contributing to the series' special appeal has been the way in which the show evolved to allow Captains Janeway and Sisko to handle the new problems they encounter, many very different from those that taxed the philosophical integrity of Kirk or Picard."--BOOK JACKET.
