When I finally got around to writing my dissertation (that’s another story), I realized that its organization easily fell into several relatively self-contained chapters. Once I defended, I needed to convert as much of the dissertation to publishable articles as I could, for the “hound of tenure” was fast on my heels.
I realized that I had written each chapter with a possible article based on it already in mind. In philosophy one often takes on positions articulated by others, and seeks to attack them in a way that makes one’s own view more plausible and defended against those who would, or should, attack it. So, I “carved” the dissertation into three chunks and wrote them up as independent articles. I sent them to the same journals that had published the articles I was attacking, and they were accepted (usually subject to some revisions). Hence, my first three publications, followed by a fourth when one of my attackees sought to defend himself in print. Those, plus a couple of short pieces, secured a tenured appointment.
