Not exactly propaganda

“The world is full of origin myths, and all are factually false. The world is full, also, of great traditional books tracing the history of man (but focused narrowly on the local group) from the age of mythological beginnings, through periods of increasing plausibility, to a time almost within memory, when the chronicles begin to carry the record, with a show of rational factuality, to the present. Furthermore, just as all primitive mythologies serve to validate the customs, systems of sentiments, and political aims of their respective local groups, so do these great traditional books. On the surface they may appear to have been composed as conscientious history. In depth they reveal themselves to have been conceived as myths: poetic readings of the mystery of life from a certain interested point of view. But to read a poem as a chronicle of fact is—to say the least—to miss the point. To say a little more, it is to prove oneself a dolt. And to add to this, the men who put these books together were not dolts but knew precisely what they were doing—as the evidence of their manner of work reveals at every turn.” – Joseph Campbell, The Masks of God: Occidental Mythology
