Similarly, the history of philosophy of science is about scientists on the losing side of first-order disputes who acquire epistemic leverage by ascending to the second-order inquiry, namely, the ideals that should guide the conduct of science. This explains the schizoid attitude of practising scientists, who are at once dismissive of philosophers' substantive scientific views, while they remain uneasy about whether their own research practices are sufficiently rational, objective, etc. However little their own practice conforms to philosophical ideals of inquiry, scientists feel compelled to justify it in those sanctified terms. Thus, science's own eternal return of the repressed helps to explain the confused legacy of the philosophy of science.
