Naturalizing the centennial: History, memory, and the limits of human lifespans

摘要

Recent studies of centennials focus on explaining the social and political contexts for such commemorations. This paper develops an alternative, naturalistic theory of these long-range anniversaries. The paper starts by describing the value of a naturalistic account of complex cultural formations, and by reviewing basic demographic and physiological facts underlying centennial observances. Next, the paper provides a novel taxonomy of three central social functions of centennials, highlighting their roles as standards of greatness, mirrors of progress, and spurs to renovation. Each of these functions reflects the existence of certain predictable limits to human lifespans. The paper concludes by considering some transformations in form and function that centennials might undergo in a potential future of extended longevity.
