Throughout history, there have been stories of the supernatural. These stories were often invoked to explain mysteries such as the origin of the world, the forces behind weather, the causes of disease, and the prevalence of coincidences. However, these stories often went beyond simple explanations and were personal accounts of people encountering things beyond natural, everyday experience. The fact that these things could also have explained some mysteries may have been interesting and possibly useful at the time, but was beside the point in many cases.

More recently, and especially over the last few centuries, many other unknowns either have not been explained by science or, like consciousness, have actually become bigger mysteries.¹ In addition, mathematics has shown that there are fundamental limits of our understanding in any rational system, and science has discovered what appear to be fundamental limits in our ability to explain physical reality.²
