The paradigms from different epochs are fundamentally incommensurate. They literally have no common measure on the basis of which they can be compared. What makes sense as a life worth aspiring to in one age might well be reviled in another. There could not have been saints in Homeric Greece for example. Ar best there could have been weak people who let others walk all over them. Likewise, there could nor have been Greek-style heroes in the Middle Ages. Such people would have been regarded as impulsive and irresponsible sinners. To be a saint or a hero is not just to behave a certain way; it is to be held up as worthy for doing so. The paradigmatic works of art for an age let certain ways of life shine forth. But in doing so they cover up what is worthy in other—radically different—ways of life.
Temples, cathedrals, epics, plays, and other works of art focus and hold up to a culture what counts as a life worth aspiring to. Works of art in this sense do nor represent something else—the way a photograph of one’s children represents them. Indeed, Heidegger says explicitly that the temple “portrays nothing.” Rather, works of art work; they gather practices together to focus and manifest a way of life. When works of art shine, they illuminate and glamorize a way of life, and all other things shine in their light. A work of art embodies the truth of its world.
