There is no period in the history of philosophy so difficult to understand as that period beginning upon Kant's death and extending up into the present. Attributing this difficulty to the proximity and contingence of the period to our own is not a satisfactory excuse, though we would be willing to admit we lack some of the clarity that “time passed” gives. If we give up the challenge of making a meaningful interpretation of this history because we lack perspective, we are surrendering a period whose lessons might prove immeasurably valuable to us. What is more important than such negative motivation for making a meaningful study of the philosophy of the last 100 years is the positive demand that we begin to develop techniques for understanding the present and immediate past, in order that we can more effectively face and contribute to the present and future.
