Economics is based on the study of unlimited wants and limited resources. However not all wants are unlimited and not all resources are of the nature of limitation. In fact many of our resources are effectively infinite given their circular recyclable and unbreakable characteristics. In a world where endless growth is seen as an objective goal by many, simultaneously many subscribe to the confining attributes of traditional economic theory domains and phenomena which find graceful landing outside the scope and purview of one quadrant of limitation and unlimitation.
Economics is historically the study of Unlimited wants with limited resources. However, not all wants are unlimited and not all resources are limited. In other words, there are plenty of phenomena that defy traditional categorization. And for these we must look to Satisologie.
By and large we can consider four distinct categories, and in each case we can consider whether something is limited or unlimited. There are many resources which exhibit both limited and unlimited behavior. For example water, oxygen, arable land all have an absolute limit on the exact number of molecules or square inches presently available, but in another sense they are unlimited and that their reuse goes on forever and is unimpeded.
