 Another view, from Pritchard (2009, 2010), is that any instance of understanding is valuable because it counts as an achievement, and achievements are the kinds of things that are distinctively and finally valuable. Instances of understanding count as achievements (and indeed what Pritchard calls strong achievements) either because they involve overcoming an obstacle or because they bring to bear “significant cognitive ability”. For Pritchard, however, the same cannot be said for any instance of knowledge. For example, in many cases I might come to believe the truth on the basis of testimony, but the credit for my true belief seems to belong more to the testifier than to me (cf. Lackey 2007). I do not reach the truth on this question primarily because of my ability or skill, but because of the ability or skill of the testifier; such items of knowledge therefore do not count as achievements, and hence lack final value.
