I am a Post Keynesian economist specialising in the science of money & the benefits of climate change mitigation. I have brought integrality into economics.

What does economic #integrality mean? The word is used in mathematics & economics. In economics, it is related to the concepts of integer & integrity, and has both an everyday & a maths meaning. It means that a resource, defined very widely to include people, is “fit for purpose”

The mathematical meaning of #integrality requires knowledge of set theory and “space-time” economics. In the set of resources, very widely defined including humans, the earth and black holes, there are good resources and bad resources.

Good resources, here and now, are a Vermeer painting, a loved hymn, Mother Earth, a view of earth from a very distant planet. Bad resources are rubbish strewn across a road, a polluted stream, a sick city.

Only some resources, here and now, are available to humans, the available set. The integrality set is the intersection of the resources available to humans and the good resources.

The following views & objects have the property of #integrality, both the real ones, & the images.
