between the different kinds of knowledge, or in this case, the experiences of the nothing, are utterly fluid. Yet, this collaboration still generates certain boundaries and often creates conditions of doubt. This is explicitly captured in the book by the story of Oz, who at some points of time deletes the author from his Facebook account and tries to avoid contact with him, while at other times Oz adds him once again and continues his interaction with him. Does this oscillation between openness and closure towards the author hint at different scales of the nothing, as well as the boundaries between the collaborators? What kind of imagination is actually co-created and shared in this case? And finally, what kind of knowledge is gained from this ‘collaborative imagination’ anyway? It is obvious that in this collaborative ethnographic endeavour one can doubt and destabilise what is seen, and through this doubting the conversation and collaboration can become quite ambivalent. It is a bit of a shame that this ambivalence is never unveiled by Frederiksen, which could allow us to gain an understanding of the nothing itself. Overall, this is a book that should be read by anyone who is interested in experimental techniques of ethnographic writing, in the wonders and ambivalences of the nothing in particular, and in the ways in which traditional ethnographic descriptions can be substituted by anthropological fiction and imagination. Frederiksen does this with great skill and brilliance, while leaving the reader wondering about the future of anthropological thinking, writing and doing fieldwork.

在不同种类的知识之间，或者在这种情况下，对虚无的体验，是完全流动的。然而，这种合作仍然会产生一定的界限，并经常产生怀疑的条件。这在书中被奥兹的故事明确地捕捉到，他有时会从他的 Facebook 帐户中删除作者并试图避免与他联系，而有时奥兹会再次添加他并继续与他互动。这种对作者的开放和封闭之间的摆动是否暗示了无的不同尺度，以及合作者之间的界限？在这种情况下，实际上共同创造和分享了什么样的想象力？最后，无论如何，从这种“协作想象”中获得了什么样的知识？很明显，在这种协作的民族志努力中，人们可以怀疑和破坏所看到的东西，并且通过这种怀疑，对话和协作会变得非常矛盾。有点遗憾的是，这种矛盾心理从来没有被弗雷德里克森揭开过，这可以让我们了解虚无本身。总的来说，这是一本任何对民族志写作的实验技术感兴趣的人都应该阅读的书，特别是对无的奇迹和矛盾，以及传统民族志描述可以被人类学小说和想象取代的方式. 弗雷德里克森以高超的技巧和才华做到了这一点，
