The crisis of memory is the most subversive and paradoxical issue among all issues of memory studies in three decades. The combination of memory and crisis itself is totally ambiguous since memory implies things past and recollection，while crisis refers to indecision and flaws.In essence，the crisis of memory stems from the linguistic turn and the rise of analytic historical philosophy，which mainly includes three questions. The base of the memory crisis is the boundary of the object of memory. The core is authority of the subject of memory. The third is stability of memory，in other words，the relationship between remembering and forgetting. All of the above is much related to ethics of memory. This paper aims at exploring the social causes of memory crisis，discussing the complicated political and cultural relations among different factors，and trying to inspire us to understand the spiritual crisis of modern people.
