Dear Dr. Grinstein: I have discussed with you a number of times the problem of my two classes at T.I. and have done some soul-searching myself these past few weeks. Of the two courses I give, the first one (i.e., the one for seniors) is usually more difficult and more advanced. It is the one into which I put my greatest energies and efforts. Yet, I am always most disappointed by the results. First, it is a required course, and hence I have many students who are not really interested in the subject matter. Second, since this is essentially a senior class, quite a number of students are absent from four to six lectures during the second semester when they are student-teaching. This is normally disruptive of class work, but especially so in a course for which there are no textbooks available.My preference is that this senior class be declared an elective, and not be a required course. Furthermore, I would want to have my other course, i.e., Philo 51-52, declared a prerequisite or at least a co-requisite for the advanced course. Frankly, if it were possible I would also want to limit enrollment in the advanced course to those with whom I can confer beforehand.The reason for this, in addition to the above, is that I am profoundly disturbed to find the lackadaisical spirit that prevails amongst so many students, and that lead me to feelings of disappointment and frustration in my own efforts at teaching.I beg of you to consider the above and, when you can find the time, perhaps we can discuss it at some greater length.Warmest personal regards,
