Natural selection is reciprocal, with the environment selecting organisms (including humans) and organisms selecting their environment. The method of natural selection in the narrow sense is to kill and let the sick and weak die, and the method chosen by human society is mainly to kill, too, without which there is no harmony. The meaning of death or elimination in the broad sense of natural selection has expanded, not only to be killed, but also to include the elimination of theories and works of art, the elimination of businesses and organizations, and the elimination in sports competitions and so on.

(1) The Principle of Social Selection of Social Organization

Major premise: the condition that any kind of social organization can survive is that the rate of reproduction of this social organization is greater than or equal to the rate of death;

Minor premise: There is imitable variation between social organizations; Some variations make social organizations reproduce faster than others, which is called having greater reproductive capacity; Some variants cause organizations to eliminate at a slower rate than others, which is called having greater survival capacity. The variations with greater reproductive ability and greater survival ability are the superior variations, and the opposite variations are the inferior variations.

Conclusion: The inferior variation of social organization is easy to be eliminated, and the superior variation of social organization is easy to survive and pass on to other organizations.

If big enterprises fail faster than they are born (for example, if the government cracks down on monopolies). After a certain period of time, there will be no big enterprises in society; If the rate of bankruptcy of small enterprises is greater than the formation rate of new enterprises, after a period of time, there will be no small enterprises in the society, and it will become a pure monopoly economy. Other organizations also have the rate of reproduction or death, including literary and technological groups, trade unions, charities, hospitals, schools, and so on. Each kind of organization can be divided into many kinds, for example, schools can be divided into universities, secondary schools, primary schools, public and private schools, as well as a variety of new educational institutions. The condition of any organization to survive is that the rate of reproduction is greater than or equal to the rate of death.
