Collective memory quite naturally brings to mind notions of mnemonic speech and representation. In this article, however, we propose that collective silences be thought of as a rich and promising arena through which to understand how groups deal with their collective pasts. In so doing, we explore two types of silence: overt silence and covert silence, and suggest that each may be used to enhance either memory or forgetting. We illustrate our conceptual scheme using data on the commemoration of slain Israeli Prime Minister Yitzhak Rabin. (Contains 1 table and 12 notes.)
