ABSTRACT
The challenge for epistemologists is to explain what needs to be added to mere true belief in order to get knowledge. Two basic requirements of knowledge: truth and belief Knowing versus merely 'getting it right'. Ability knowledge is certainly an important type of knowledge to have. To have knowledge, one's success must genuinely be the result of one's efforts, rather than merely being by chance. In particular, epistemologists need to explain what needs to be added to true belief to capture this idea that knowledge involves a success that is creditable to the agent, where this means, for example, that the agent's true belief was not simply a matter of luck. As with the truth requirement, epistemologists will assess the plausibility of the belief requirement for knowledge by imagining for a moment that it doesn't hold, which would mean that one could have knowledge of a proposition which one did not even believe.
