Coherence could be defined relative to other, more objective systems, however. Introduction a. Some preface their book by claiming that, given human frailty, they are sure that errors remain, errors for which they take complete responsibility. The idea behind an appeal to the basing relation is that if the explanation of a person's belief does not appeal to the evidence for the belief, then the belief itself is not justified even if the person has good evidence for the belief and thus the content of the belief is, in some sense, justified for that person. At a minimum, coherence requires logical consistency. Thus arises the regress problem in epistemology. In response, Lehrer , p. Since the theory implies its empirical consequences, the conjunction will, in ordinary cases, have a higher probability than the theory since it is a theorem of the probability calculus that if A entails B, then the probability of A is less than or equal to the probability of B.
A beautiful and elegant theory of this sort is a version of probabilistic Bayesianism. Against Sufficiency: The Alternative Coherent Systems Argument A second argument against sufficiency coherentism connects in some ways with the last argument. Lehrer, Keith.
Apart from this superficial fact, these theories often address some rather diverse issues loosely united by the fact that they in one way or the other take a holistic approach to the justification of beliefs.
One issue here concerns whether each source, taken individually, provides justification for believing p.
Foundationalists, at least moderate foundationalists, have just as much at stake in the project of identifying these canons. The fact that coherence and incoherence are contraries explains the earlier point about why deeming incoherent beliefs unjustified is not enough to make one a coherentist.
It follows that coherence and incoherence are contraries, not contradictories. Where the circularity charge targets the coherentist claim that beliefs are justified by standing in support relations that are mediated by other beliefs but ultimately return to themselves, the self-support charge focuses on an alleged implication of this, namely that beliefs are therefore justified at least in part because they stand in support relations to themselves.
Foundationalism coherentism and infinitism
The resulting theory would be one in which experience plays a role, but not the kind of role that is distinctive of foundationalism. According to BonJour, invoking cognitively spontaneous beliefs in this way explains how experience can make a difference to the justificatory status of our beliefs — experiences do this via their being reflected in a subset of our beliefs. It is probably only in moral epistemology that coherentism enjoys wide acceptance. Early characterizations were given by, among others, Brand Blanshard and A. Totowa, N. It would be easy if the justificatory level simply matched the overall coherence level for the system itself, but this easy answer conflicts with the fact that not all beliefs are justified to the same degree. The worry is that appealing to experiential states in any way will result in a version of foundationalism. For notice the argument had us begin with an individual belief that was justified, though conditionally so. But to possess a reason is to believe that reason. The third criterion stipulates that the degree of coherence increases with the number of inferential connections between different parts of the system. Bender, John, ed. It is not clear, though, that coherence does hold between these.
Doing nothing will certainly not work, but among the various actions available, we can only choose and hope for the best.
