This book strives to tackle many "big" questions, so it is somewhat difficult to choose just one or two dominant themes. That being said, one major issue discussed in the book is that of globalism. Harari suggests that just by virtue of living in the modern age we are necessarily part of a global society. So even though it sometimes seems like we are competing with or even warring with other countries, Harari writes that this international collaboration “actually represents an astonishing global agreement.”

Another theme is that the plethora of information that humans receive on a daily basis makes it increasingly difficult to make educated and non-biased decisions. When we turn to so-called "experts" for help, how do we know that the advice we're receiving isn't tainted by that person's own prejudices? Harari contends that it is easier than ever to insulate ourselves—especially with social media—by networking only with people with whom we always agree.

Harari discusses many other matters and concludes that one of the most helpful things we can do is to meditate. Although Harari is not naive enough to think that meditation will instantly solve all of the world's problems, he does posit that self-awareness and mindfulness is the key to understanding how we ourselves contribute to unhappiness and misery in the world.
