What is required is also coherence with a system resulting from correcting the errors in the background system. This is the basic idea of the coherence theory of truth : what is true is what is coherent with a given set of propositions (or beliefs, since believing is an. The key point against the coherence theory of truth is that coherence with currently available evidence supports the view that reality is independent of representation of it.
One’s background information might be largely erroneous, so coherence with it (together with truth) is not sufficient for knowledge. correspondence theory of truth, because we can consider the fit, or lack of fit, between current representations and the state of reality at that time. But this sort of justification is merely “personal justification”.
It is in the tradition of undefeated justified true belief analyses. In two recent papers (19), Keith Lehrer has developed the coherence theory of knowledge and justification that he originally proposed in Knowledge, In broad outline, Lehrer’s new view is that one has knowledge when “the right combination of internal and external factors” are present, and this obtains when there “is a rational connection between subjective states and truth.” (1988, 330) Knowledge requires the proper “evaluation of incoming information in terms of background information.” (1988, 330) When a proposition coheres with one’s new information and one’s background information, it is justified.
