Over 500 years ago, Leonardo DaVinci quipped, “We know more about the movement of celestial bodies than about the soil underfoot.” Amazingly, it is still true today that we know less about the living ecosystem under our feet – the soil – than we do about the far side of the moon. Yet, every plant and animal on our planet depends on these living systems that provide many of the most fundamental functions needed for life.

It is also true that people know very little about the foundations of their beliefs and ways of thinking.
