我們真的能夠知道彆人的心思嗎？女人有可能瞭解男人的感覺嗎？嬰兒在分娩過程中的體驗如何？胎兒在子宮裏如果有體驗的話，是什麼樣的呢？非人類的心靈又如何呢？馬在想些什麼？禿鷲吃瞭腐屍為何不會嘔吐？當魚的嘴唇被鈎住時，它會不會像你的嘴唇被鈎住時那樣痛呢？蜘蛛們會思考嗎？機器人是否會像人那樣感覺得到疼痛，並為自己的未來操心呢……

那些問題，它們曾不止一次縈繞在我們的腦海，我們也不指望誰能夠以科學上的論據來給講清楚，但是，現在有科學傢在認真地講瞭。丹尼爾·丹尼特是美國著名的哲學傢和認知科學傢。他在《心靈種種》這本書裏，試圖用一種更形象和令人信服的方式讓人們瞭解“心靈”。作者以廣闊的視野和清晰的框架，用生動和豐富的例子，探討瞭心靈的起源與結構。全書深入淺齣，引人入勝，既有各種鮮活易懂的實例，也有從哲學、人工智能、神經科學角度的理論闡述。

Combining ideas from philosophy, artificial intelligence, and neurobiology, Daniel Dennett leads the reader on a fascinating journey of inquiry, exploring such intriguing possibilities as: Can any of us really know what is going on in someone else’s mind? What distinguishes the human mind from the minds of animals, especially those capable of complex behavior? If such animals, for instance, were magically given the power of language, would their communities evolve an intelligence as subtly discriminating as ours? Will robots, once they have been endowed with sensory systems like those that provide us with experience, ever exhibit the particular traits long thought to distinguish the human mind, including the ability to think about thinking? Dennett addresses these questions from an evolutionary perspective. Beginning with the macromolecules of DNA and RNA, the author shows how, step-by-step, animal life moved from the simple ability to respond to frequently recurring environmental conditions to much more powerful ways of beating the odds, ways of using patterns of past experience to predict the future in never-before-encountered situations. Whether talking about robots whose video-camera ”eyes” give us the powerful illusion that ”there is somebody in there” or asking us to consider whether spiders are just tiny robots mindlessly spinning their webs of elegant design, Dennett is a master at finding and posing questions sure to stimulate and even disturb.
