and you're lucky this evening to have robert j. lifton here, it seems to me. but i'll tell you why i think you're lucky but i also want to give you a warning. and i'd just take a minute or so. you're lucky as he has a psychohistorian, a unique perspective on history because he deals with great subjects. and, you know, if you look at these books here, i haven't inspected all of them but among his subjects are the nazi doctors and medical killing, the nuclear threat, the psychology of genocide, the survivors of hiroshima, capital punishment. these are huge subjects that hang over us and everybody out there. my warning is that robert j. liftedon is the ultimate geographer of moral responsibility and it's impossible to listen to him talk without getting a sense of your own -- of the moral dimensions of what you do. and those of you who are students here it seems to me that you can't listen to him without understanding that your job is not merely to report on the moral responsibility of others. but to behave in a moral responsible away yourself. it's an honor and p
