The question "What is postmodernism?" is akin to "What is literature?" or "What is philosophy?"At least with vampires, you're safe during the day. Zombies are the undead you really need to worry about.
If Heidegger can be trusted (hold that thought), such a question can't be answered in any rewarding manner without delving into philosophy, in which case philosophy then speaks for itself.
The danger of articles such as last week's from de la Fuente is that they are neither philosophy nor criticism; they cannot serve to answer, defend, attack or criticise philosophy in any kind of meaningful way.
They are a long-winded echo of a trend that began and ended five years ago, and in de la Fuente's case, a spiralling justification for the use of the term "vampire discipline".
