In fact, the thesis of this book is that our conceptualizations of death so profoundly shape cultural meaning that any change in the quality of death' or in the envisioning of the hereafter is amplified through the entire social order, bringing changes from top to bottom, from the relative power of different social institutions to the language in everyday life. Another way of looking at culture is as a legacy which living generations have inherited from those of the past. F. Lloyd Warner (1959), for instance, 24 ENDINGS defined human culture as the symbolic organization of the remembered experiences of the dead as it is felt and understood by the living.

In the East, the ultimate goal is often an undifferentiated and impersonal oneness with the universe. • Cultures have taken hedonistic and pessimistic orientations toward life in facing the inevitability of death. One can take an "eat, drink, and be merry, for tomorrow we die" approach to life. There is, for instance, some evidence that many members of the American baby-boom generation, realizing that they are the first downwardly mobile generation in American history (Longman 1985), watching their parent and grandparent generations' frugal life-styles ending either in premature death (and, therefore, never enjoying the retirement that was being saved for) or in massive medical bills for various ailments and illnesses (Ruffenach 1985), now spend their savings for self-indulgent life-styles.

This central, irreducible problem is becoming disentangled from the problem of adjusting to deaths that occur earlier in the life cycle, particularly in infancy and early childhood, which was much more general in the pre-modern period. (1967, p. 137) As we will see in the chapters to come, this has led to concerns with the quality, as opposed to the quantity, of life as well as to individuals5 fears of incompleteness. Changes in the Quality of Death With medical and technological innovations, death comes in slow motion to individuals isolated in institutions for the dying.
