The two-phrase interpretation

I read this quote on the Internet, attributed to Beethoven, but I have never seen it elsewhere. Who can confirm it?
"Playing a wrong note is insignificant, playing without passion is unforgivable."

. . . anyway I have always thought so too.

Even if he never had the courage to write it on the internet . . . Let's hope it is Beethoven

I doubt it is a quote from Beethoven. I agree with this statement, however. A wrong note can happen to anyone, but in my opinion, this slogan should not be interpreted as an alibi for which everything is permitted as long as there is a good interpretation. When preparing a musical piece, one must always bring it to the maximum of both technical and interpretative execution; then, of course, in concert, some notes are missed, partly due to emotion, partly due to playing on a piano that might have some issues. It's all fine as long as it is not an alibi for studying less and preparing pieces, as they say here: "All'acqua di rose" (easy-peasy/without effort).

I find the comment fair. Success, if one has studied well, also depends heavily on two other things: the capacity for long-term concentration and believing that you "can do it." Glenn Gould used to say: "when you are about to perform a difficult passage, a moment before, never doubt that you can do it! Nothing is more destructive." Then for the rest, one must study conscientiously without leaving anything to chance or to the understanding of the text. Technique, at the service of Music, as I firmly believe, can no longer be separated from the musical context. Sometimes Music itself suggests the solutions to us, now and forever. Overcoming a passage means internalizing it and understanding it forever. Understanding forever the right "pianistic gesture" and the fingering that is natural to us. I remember, in my first youthful approach to Beethoven's Appassionata, having searched for the solution in a passage of the development in the third movement for days. Once I was on a bus and the probable solution "appeared" to me. I couldn't get off because we were in traffic. I took a piece of paper I had in my pocket and a pen and noted down the probable fingering. Looking up from my seat, I met the gaze of a gentleman who was perhaps worried about my mental health, seeing me noting down strange numbers on a series of "black dots with little legs" on the paper. Fortunately, the stop was near and I immediately took the return bus that brought me home.

On social media, the aforementioned quote is gaining more and more ground, "Playing a wrong note is insignificant, playing without passion is unforgivable", which is attributed to Beethoven, but I have never read it anywhere. Can any Beethoven expert, for example Armando Orlandi, confirm or deny this?
