Sensory abilities of humans and bats are different. The latter have ultrasonic sonar that helps orientate in space. Let's suppose we learned everything about its nature. But do we know what the bat’s conscious experience is, “what is it like to be a bat?” Intuition tells you no. And this means that even the most ideal materialistic explanation leaves out special facts—the facts of consciousness, "what it is like to be those who we are." It is for this reason that consciousness is so mysterious, it is an abnormal phenomenon for natural science.
