Shelly Kagan is the Clark Professor of Philosophy at Yale University. His course titled Death is available free online through the Yale Open Courses. http://oyc.yale.edu/philosophy/phil-176
Prof. Kagan is an excellent lecturer, and the course is more interesting than it sounds. He teaches from a philosophical, not a biological, point of view.
This is the course description: This course will examine a number of issues that arise once we begin to reflect on our mortality. The possibility that death may not actually be the end is considered. Are we, in some sense, immortal? Would immortality be desirable? Also a clearer notion of what it is to die is examined. What does it mean to say that a person has died? What kind of fact is that? And, finally, different attitudes to death are evaluated. Is death an evil? How? Why? Is suicide morally permissible? Is it rational? How should the knowledge that I am going to die affect the way I live my life?
