1, productivity and relations of production

A business is a contradiction in terms, it is clear that it has to be established and run, first of all, there must be employees, things have to rely on people to do, which is the productive forces; however, more people, a plate of scattered sands can not be, there must be a leader to make decisions, command, there is a division of labor.

There must also be a set of rules and regulations, we have to comply with, there are no rules, not round, which establishes a productive relationship. With these two, the enterprise can run, the lack of one is indispensable, this is the contradiction between the two sides of the interdependence, unity.

2, spear and shield

The spear is the weapon of offense, the shield is the weapon of defense, the two are opposites. If there is no spear offense, there is no need to shield defense, so the two are interdependent, the lack of which one, the other will lose the meaning of existence, is a unified whole.

3. "There are those who live, who are dead; there are those who die, who are still alive." --Zang Kejia, "Some People"

In the view of common sense, a person is either dead or alive, and one must be one of the two. Is not the poet's statement self-contradictory? If life and death are understood to be merely the existence or non-existence of the physical body, there is no doubt that they are opposites.

But, in the dialectical view, one's existence means both physical and spiritual; one's death can be both physical and spiritual.

In these two senses, life and death are again united. In the author's view, a person's body can rot, but the spirit can live forever, though death is still life; although a person exists in the physical sense, but has lost the spiritual pillar, just like the walking dead, though life is still death.

4. Cicadas are more quiet in the forest than in the forest, and birds are singing, and the mountains are more secluded - Wang Ji's "Entering the Ruoxi Stream"

The vernacular translation is: Cicadas are clamoring, the forest is more and more silent; the birds are chirping, and the mountains are more secluded.

The poet's description of the tranquility of the forest does not begin directly with the tranquility, but with its opposite, the noise, contrasting the sound of cicadas with the tranquility of the forest. The description of the mountain does not come directly from "you," but from its opposite, "song," which is the song of the bird to the mountain. Noise and quiet, singing and quiet form a strong contrast, and constitute a harmonious unity, high meaning, philosophical rich.

5, the unity of opposites (unity, unity, balance) is conditional, temporary, perishable, relative. The struggle of mutually exclusive opposites is absolute, just as development and movement are absolute. -- Selected Works of Lenin

The absoluteness of the struggle of opposites and the relativity of unity reflect, in a highly general way, the different positions of struggle and unity in the movement of contradictions and their mutual relations. Only on the basis of this principle can a complete and regular explanation of the process of contradictory movements of things be made.

The absoluteness of the oppositional struggle refers to its universality and unconditionality. Oppositional conflict is a positive and dynamic aspect of the movement of contradictions, which can break the limitations of various conditions and create new conditions for the development of contradictions.

There is a struggle when there is a contradiction, and there are no conditions for the struggle, and the tendency of mutual exclusion of opposites must be practiced under any conditions.
