The Smart Set: The Metaphysics of Cutting Grass – August 5, 2010: “Perhaps I yearn too much to hear my echo in the world. Yes, occasionally, I do hear from a former student, several years out, that something I said or did has assumed some meaning in their lives. And certainly I understand that students are with me only for 50 minutes three times a week, and that the results of instruction oftentimes reveal their value only in the fullness of time. Still, I find it troubling when, over the course of a semester, I see no palpable impact; I begin to doubt myself, feel vaguely fraudulent. Thus the satisfaction I find in cutting grass: When I’ve finished, I can see, clearly see, a genuine accomplishment, a consequence of my contact, a change in the physical, ‘out there,’ external reality wrought by my expended effort.”

Selfishly, I’ll say exactly.
