The organization of thought as a series of nested loops, each encompassing the others, is a general phenomenon. It can be found in the ways in which intelligence is organized in our bodies and within the groups we’re part of. The efficient deployment of energy to intelligence depends on a similar logical hierarchy that takes us from the automatic and mindless (which require little energy) to the intensely mindful (which require a lot). With each step up from raw data, through information to knowledge, judgment, and wisdom, quantity is more integrated with qualitative judgment, intelligence becomes less routine and harder to automate, and crucially, the nature of thought becomes less universal and more context bound. With each step up the ladder, more energy and labor are required.
