We combine Maslow's hierarchy theory of needs and farmers' rationality and confirm that farmers do have rationality and it is in a dynamic condition.展开更多

The theory is mathematical in the strictest possible sense. The mathematics involved is strictly digital—not quantitative in the manner that what is usually thought of as mathematics is quantitative. It is anticipated at this time that the exclusively digital nature of rational human intelligence exhibits four flavors of digitality, apparently no more, and that each flavor will require a lengthy study in its own right.
