An example of the dialectical relationship between reality and possibility is the airplane. Since ancient times, human beings have dreamed of flying in space like birds. Mozi, Lu Wen recorded that the loser cut bamboo and thought it was a magpie, and flew away three days later. This is the earliest record of manned flight. In the Middle Ages, the first experimenter of airplanes was Abbas Fermas, an Arab.

Possibility and reality are both different and related, and they are the relationship of unity of opposites. Possibility is not equal to reality, and reality is no longer possibility. There is a clear distinction between the present and the future.

Realistic and possible significance

The so-called possibility refers to all kinds of potential trends in things that indicate the future development of things, and the so-called reality refers to the possibilities that have been realized and the things that have actually existed.

They are interrelated and transformed. Possibility has not been developed, and potential reality and reality have been developed and realized. Possibility always lurks in real things, and real things always develop from some previous possibility.
