I tend to agree with Professor Tolkien. Isn't the thought of death a search for the bottom line? Isn't the vision, the acceptance, the reluctance, or even a brush with death set our minds upon the meaning of life?
I am not a writer, just a reader. But death as a topic or theme gets my attention going towards purpose and meaning quicker than say leaves on a tree, flying balloons, or a wedding. I'm not saying that leaves, balloons, nor weddings don't have any place in speaking on the purpose of life, but they don't grab my attention as easily nor as quickly as death.
Just to comment upon Tolkien's pronounciation.... As an educated fifty-seven year old American, who has lived in the Midwest/the South/the West Coast/the Great Plains (and Taiwan), I find myself comprehending about seven to eight words out of ten spoken by Tolkien. This really makes me doubt my education, my love of the English language, my ardor for Tolkien's works, and my respect for the man himself. How much of the meaning of Tolkien's English and stories am I missing?
