This chapter seeks aid from Thomas Kuhn's work in the 1960s and 1970s in order both to diagnose and to aid the recovery of early twenty-first-century history and philosophy of science. It begins with a statement of the current high entropy state of history and philosophy of science in order to ask a few questions of how, in the wake of Kuhn's work and in Kuhn's work itself the relations between history and philosophy of science were conceived. In some remarks of Kuhn on the reading and writing practices of historians and philosophers, the chapter finds some hope for a new project of reflexive articulation of the goals and methods of, especially, philosophy of science.
