I remember that Hahn used to speak often about the Eros of Teaching.  Strangely I don't remember anything specific.  I haven't been able to find anything as yet in my father's lecture notes.  So I did an online search and found a brilliant article by Kathleen Hull about the Eros of Teaching and how it can be used effectively in the classroom.  I attach it because of its importance.

Here, in brief, is what I gleaned from Hull's article:

Teachers and students are notoriously known for becoming sexually involved.  But this isn't the Eros of Teaching.  The Eros does have a physical element of desire, but it is more about the passion, excitement and joy of finding someone with whom one can share a common desire for knowledge.  If someone becomes passionate about politics or literature, it is most likely because the person had a person or group who inspired this passion---the eros.

The most effective way of inspiring Eros in a student is for the teacher to admit their own lack of knowledge (ie. Socrates and his "I know nothing").  The teacher's acknowledgment of his own lack helps the student recognize their own lack.  Love is the pursuit of what one lacks.  The Eros is the pursuit of this love.  The teacher cannot fill the lack, but can go in pursuit of the love together with the student, filling his own lack in the process.

This article was haunting.  It explained most of my academic life, revealing to me all the instances of Eros with professors, and those instances in which I have been the object of Eros to others.  It makes Hahn's loss all the more difficult.  Even though I hadn't seen him in years, I knew he was out there and available.  I am in pursuit, but he was potentially available to be present. 

Now I feel alone and dislike the idea that I might be the teacher to others.  It's a repugnant responsibility.

This is another handout I reconstructed.  It was written by Shelly Kopp, author of Guru: Metaphors from a Psychotherapist.

Retyping it made me realize that I should still have it on my wall.  There are 43 things on the list.  When Hahn discussed the list in class, there were nine things he had us star as particularly important.  I'll give those now, and add a pdf of the entire list.

5.  Nothing lasts!
17.  There are no great men.
18.  If you have a hero, look again; you have diminished yourself in some way.
19.  Everyone lies, cheats, pretends (yes, you too, and most certainly I myself). 
25.  Childhood is a nightmare.
27.  Each of us is ultimately alone.
36.  You can run, but you can't hide.
38.  We must learn the power of living with our helplessness.
43.  Learn to forgive yourself, again and again and again and again.
