This is one of the best books ever written. It is science fiction, funny (Typically British humor), Engaging and inspiring. It contains lots of philosophical musings, as well as thoughts about politics, psychology, and you name it - but is always light hearted. Meanwhile, in my humble opinion, the author thesis in large catches truths funny and easy-to-read stories.
You will learn Who made the earth and why, how The Most firendly and innocent people May turn out to be The Most Dangerous, Who really rules the universe, and much more.
Do not miss the description of the economy of the first people on earth.
