如果上帝存在该如何?如果有善恶,我们该如何?我们如何知道什么是真的?我们能使宇宙和我们的生活有意义吗?这本书对这些问题进行了探讨。其话题包括自由意志,宇宙的性质,生命的意义,指出,没有上帝,人们一样能够使生活充满爱、充满意义、充满乐趣。这本书也是对其时代的挑战:不论是否同意他的观点,每个人都需要独立思考宇宙人生等一些重大问题。 If God exists, what should we do if there is good and evil? How do we know what is real? Can we make the universe and our lives meaningful? The book explores these issues. His topics include free will, the nature of the universe and the meaning of life. He pointed out that without God, people like to make life full of love, full of meaning and full of fun. This book is also a challenge to its time: Whether or not it agrees with his point of view, everyone needs to think independently of cosmic life and some other major issues.
