We take a classic of philosophy and ask an outstanding scholar in the same field to review it as if it had just been published. This implies that the classical work must be contrasted with both past and current literature and must be framed in the wider cultural context of the present day. The result is a litmus test for the work itself: Failure in accounting for relevant issues raised by contemporary literature reveals that, in those respects, our classic has indeed been outpaced by later works. On the other hand, any success in capturing core topics of current discussion, or even anticipating and clarifying issues not yet well brought into focus by contemporary scholars, is the strongest proof of the liveliness of the work, no matter how long ago it was written.
I have enjoyed reading some of the previous "Untimely Reviews," including for example Brandom on Hegel's Phenomenology (2008) and Leitgeb on Carnap's Aufbau (2009). Readers not familiar with the series should check it out.
(I should note that my "untimely review" will not include that many new ideas for those who have been reading some of my other Nietzsche essays of late--I've been working on, and writing about Twilight quite a bit over the last two years.)
