I examine the implications of knowledge‐first epistemology for philosophy of science. We start with the idea that belief aims at knowledge. Correspondingly, I claim that scientific belief and science itself aim at scientific knowledge. This implies an account of scientific progress as the accumulation of scientific knowledge. More importantly, I argue that we can also infer an account of scientific evidence: science aims at producing knowledge by making inferences from evidence; science can achieve this if and only if evidence is knowledge. This knowledge‐first equation, E=K, runs counter to empiricist conceptions of evidence and observation as tied to perception. I note that it provides an answer to problems raised by the Duhem–Quine thesis. It also enables a picture of science that allows that as hypotheses come to be known the evidential basis of science can become ever more ‘theory‐laden’ in a benign way, allowing for further scientific progress.
