Evidence and Justification

Among the evidence concepts that Peter Achinstein has defended is one (ES-evidence) that he claims is based on the idea of providing an epistemic justification for belief. To the contrary, This chapter argue that his account of evidence lacks a substantive account of epistemic justification. To remedy this, This chapter propose an ideal of justification that this chapter argue is compatible with his account of evidence. This chapter's proposal does not introduce any new notion of evidence, but articulates instead a relativized, non-probabilistic notion (the securing of evidence) that helps make sense of certain strategies by which scientists justify their claims about what evidence they have and their inferences from that evidence. This chapter illustrate this framework by drawing upon a historical episode about which Achinstein himself has written: Heinrich Hertz's cathode ray researches.
