higher than wisdom
the soil in which the spirit
lives, thinks and invents

From the quote, Music is a higher revelation than all wisdom and philosophy. Music is the electrical soil in which the spirit lives, thinks and invents, which is credited to Ludwig van Beethoven (1770-1827) by Bettina von Arnim in a letter to Johann Wolfgang von Goethe, May 28, 1810.
SO did he say it?
Maybe.
Can I prove he did through a letter that purports to quote him?
Maybe.
Does it matter?
Nope.
Once more …
Music is a higher revelation than all wisdom and philosophy.
Music is the electrical soil in which the spirit lives, thinks and invents.
And as Fran Leibowitz says, “Music makes people happier, and it doesn’t harm them. Most things that make you feel better are harmful. It’s very unusual. It’s like a drug, that doesn’t kill you.“
Regardless, Happy Birthday Mr. Beethoven.
And to return to your words from other people’s letters, as you said on your death bed, Applaud, my friends, the comedy is over.
