As an astrophysicist, that is, a man who is closer to the stars and higher above the earth than the rest of us, Neil deGrasse Tyson offers an overhead look at the painful points of our civilization - war, politics, religion, truth, beauty and differences between people - - in order to more acutely feel our unity. In times when contradictions have reached the peak, the author offers an antidote to hostility - a cosmic perspective and the rationality of science, the main pillars of enlightenment. By thinking deeply about the Earth as a planet and how scientists look at the world, we are still able to re-set priorities and rebuild our value system. The author reminds us of our place in the vast Universe and how precious life is and what is built on this maxim the main truths about the world and man.
