The 23 Best Books on Atheism, Free-Thinking, and Humanism

The Portable Atheist by Christopher HitchensOn the issue of god, you must take a position; you either believe that you exist according to some divine plan or else think your existence can be explained adequately by the laws of physics and biology. And this is no small thing; your answer to this will impact all of your other beliefs.

The topic of god and religion is fascinating because it segues into almost every other area of intellectual discourse. The question of god’s existence invariably leads to questions of existence and reality (metaphysics), the nature of knowledge and what can be known (epistemology), and the foundation of ethics and morality and even society.

As such, it’s an important topic for both the believer and unbeliever alike. Simply identifying as an atheist doesn’t automatically make you a free-thinker if your beliefs are merely the result of an unquestioned acceptance of someone else’s thinking. The designation of free-thinker is reserved for those who fully engage with the arguments and in the process form their own beliefs.

If you’d like to dive deeper into humanity’s oldest debate, here are 23 of the best books on atheism, religion, secularism, and free-thinking:

  1. Why Evolution is True by Jerry Coyne — a succinct and accessible summary of the facts supporting the theory of natural selection.
