Final answer:
The myth of the Metallic Races of Mankind presents a view of progress and decline in the relation between past and present, with each subsequent age being seen as of lower value. An example of this view can be seen in the transition from the Golden Age to the Iron Age.
Step-by-step explanation:
The myth of the Metallic Races of Mankind (gold, silver, bronze, heroes, iron) presents a view of progress and decline in the relation between past and present. It suggests that humanity has gone through different stages or ages represented by these metals. Each subsequent age is seen as being of lower value and quality compared to the previous one, indicating a decline in human capabilities and virtues. An example of this view can be seen in the transition from the Golden Age, symbolized by gold, to the Iron Age, represented by iron. In Greek mythology, the Golden Age was a time of peace, harmony, and prosperity, while the Iron Age was characterized by strife, violence, and moral decay.
