In the following paper I intend to prove unequivocally that the line of Greek philosophers beginning with Socrates and ending with Alexander the Great matches up 100% with the teachers and students at the mighty organ of St. Sulpice Cathedral in Paris from the mid-nineteenth to mid-twentieth-ish centuries.
As a little background, about 2,400-oid years ago, Socrates taught Plato, Plato taught Aristotle, and Aristotle taught Alexander the Great. And using the same rough-style estimate, something like a century years ago, Charles-Marie Widor taught Marcel Dupré, Marcel Dupré taught Jehan Alain, and Marcel Dupré also taught Jeanne Demessieux, as far as the current body of evidence can tell, all on the same organ.
Socrates is Charles-Marie Widor
Plato is Marcel Dupré
Aristotle is Jeanne Demessieux
Alexander is Jehan Alain
Aside from the obvious that Alain and Alexander were both involved in horrible wars, the similar lines of succession is further cemented by the fact that Widor (21 February 1844 – 12 March 1937) was 93 at his time of death, Socrates being 71. And since 3 is the next odd number after 1, and 9 is the next odd number after 7, I think you see where I'm going here.
Besides, if you listen carefully to each number I linked to (which those of you many years from now, when Youtube is too quaint, can find in the reference section) you'll note that each one musically encompasses the overall thought of each philosopher the specific organist is coupled with.
Now, one objection I anticipate (a rhetorical technique known as "hypobole") is that Socrates did not put any of his philosophies into writing, whereas there is plenty of organ music written by Widor. This is a false dichotomy: no where is it argued that Widor was expected to pen philosophies, nor was Socrates expected to write organ music, an instrument that wasn't even invented until the sixteenth century, millennia after his death!
Those who forward that Alexander the Great was Macedonian, and not Greek, need to crack open a history book: as Macedonia is a separate country these days, but Alexander was from Macedon, an ancient Greek state, not from Macedonia, which didn't even exist until 1991.
Some would say a jarring difference is that Alain and Demessieux were both students of Dupré, whereas Plato never taught Alexander the Great – but in another sense, didn't Plato "teach" Alexander the Great through and in Aristotle? So in that sense, which turns out to be the only sense that you can honestly adopt, Plato did teach Alexander the Great in the exact same way that Marcel Dupré taught Jehan Alain.

I rest my case
