  A plausible account of the purpose of the justification component in the traditional tripartite analysis of knowledge is that it disqualifies accidentally true beliefs — beliefs that happen to be true, but are based on no good reason — from counting as knowledge. The Mohists handle this issue implicitly, by acknowledging only reliably correct distinction drawing as knowledge. Here again, their conception of knowledge reflects their overall focus on practical performance. Fundamentally, for them knowledge is not a correspondence between a mental state and the world, but an ability to perform certain skills reliably and correctly.
