This article shows that the debate about the possibility and desirability of a rigid distinction between discovery and justification is being muddled because of differences and ambiguities in the way that different writers use the terms ‘discovery,’ ‘justification,’ and related terms. The article argues that merely distinguishing between ‘discovery’ and ‘justification’ is not precise enough, and that we should make a distinction between different elements within each of these contexts. I propose a six-fold classification, through which we can identify reasons, acts, and processes that play a role both in the context of discovery and in the context of justification. This six-fold classification enables us to move forward from debating whether discovery and justification can be rigidly separated, towards articulating how each element (reasons, acts, and processes) has a role to play in each of the contexts (discovery and justification), and how these elements and contexts are related.
