Nihilism is not an existential quandary but a speculative opportunity.

Psychoanalytic categories such as "neurosis", "psychosis", "mania", and "fixation" have become part of our everyday psychological vocabulary and we now routinely interpret states of anxiety, excitement, or depression in terms of physiological factors involving levels of serotonin, adrenalin, or blood sugar. To say that the characterization of thinking has a normative function that is irreducible to neurophysiological processing is not to say that our extant classification of the forms of thinking is incorrigible.

Like many, I suspect, I found the difficulty of analytic philosophy unglamorous and therefore less appealing. This is regrettably superficial but superficiality is characteristic of youth. In my late teens I became enamored of Nietzsche, Bataille, and Artaud.

It was Kant who first rejected the Cartesian premise of the mind's self-transparency: the idea that when it comes to knowing our own minds, we just know what we are thinking or feeling, and do not have to learn how to perceive ourselves thinking or feeling.

I was trying to develop a notion of "non-dialectical negativity" as part of a concept of extinction that would transform the understanding of death and time elaborated in phenomenology.

Philosophy would do well to desist from issuing any further injunctions about the need to re-establish the meaningfulness of existence, the purposefulness of life, or mend the shattered concord between man and nature. It should strive to be more than a sop to the pathetic twinge of human self-esteem. Nihilism is not an existential quandary but a speculative opportunity.

Philosophy ought to be able to give an account of rationality that is not wholly detached from science's account of nature, even if it is not straightforwardly reducible to it.
