Tolkien on tradition and transmission

From “The Tradition of Versification in Old English,” a draft lecture by Tolkien included in the recently published volume The Battle of Maldon together with The Homecoming of Beorhtnoth, which I’ve been reading this week during my vacation:

 
But a poem perishes even as it is being uttered. To live it must be preserved in memory and be after repeated. And men die quicker than pictures or monuments; and the time soon comes when the memory must pass into a different mind and the repetition to another mouth, or perish.
— JRR Tolkien
 

Tolkien’s lecture is primarily concerned with aspects of Anglo-Saxon verse forms and the perceived defects—according to earlier critics—of the verse of The Battle of Maldon, but in this early passage he makes a number of thought-provoking big-picture observations on how traditions are organically passed down and preserved.

I think this is an underappreciated aspect of tradition even, or perhaps especially, among conservatives of my stripe: it is not enough to pass things along to the next generation. Tradition must not only survive the transition between generations, but between different kinds of minds. That is, to survive, a tradition must be willingly preserved among people who, because of the changeability of human culture and the inevitable and steadily accumulating alterations of culture, are radically different from those who began the tradition. Those who care to preserve and pass on are therefore dependent upon people we will never meet, people whose backgrounds are unimaginable to us now, to continue that project.

I think this makes forming future generations to be those willing and able to imagine minds other than their own—those who are, according to Chesterton’s definition, not bigots—that much more crucial.
