While our higher-level thinking makes us unique among species, it can also make us uniquely confused. Other species have much simpler and more straightforward lives, without any of man’s wrestling with what’s good and what’s bad. In contrast with animals, most people struggle to reconcile their emotions and their instincts (which come from the animal parts of their brains) with their reasoning (which comes from parts of the brain more developed in humans). This struggle causes people to confuse what they want to be true with what actually is true.
