In the wider context you have graced me with here, I find much to agree with. Particularly this.
"...it is doubt that must not lose its justification in any case."
That is the place I try to live in, and why I was led to reply as I did, noting I exemplified Dunning Kruger and that I needed to doubt my own competence and belief in my understanding.
"Have you ever been surprised, in a positive sense, by the opening of the space beyond expertise, for example, by someone you did not expect?"
Very much so. I confess it is my experience at the moment, as I have grossly misunderstood your initial comment regarding unbelief in the contagion theory, and expected an explication of terrain theory.
Instead I find compassion in it's place. I find that extraordinary, and very, very refreshing.
Thank you for that.
