The Art of Conversation - the next to final list!

For those of you who have been reading my blog, you may remember that I had been mulling over a list of people from the past I would have liked to be in conversation with, the ultimate goal being the selection process from a semi-final list of four, then boiling it down to one.
The following are the great names I had been considering, for reasons expressed in ten blogs I have submitted to you over the past few months:
Ludwig Von Beethoven
Franz Liszt
Robert Oppenheimer
Albert Schweitzer
Albert Speer
George Handel
Alexander Scriabin
Oscar Levant
Peter Tchaikowsky
Mel Torme
Mary Shelley
Oscar Wilde
Serge Prokofiev
John Hasson
From the above list, I have eliminated all the names, save for the final four:
George Handel
Oscar Levant
Franz Liszt
Albert Schweitzer
Keep in mind that this is only a kind of 'game,' as I fully expect the reader to disagree with many names having been listed - please be reminded that each name that appears was chosen through my eyes only, and this entire process is merely a personal reactive adventure into a world of the genius mind.
Stay tuned!
