 The mere rejection of foundationalism is not itself an alternative theory because it leaves us with no positive account of justification, save a suggestive metaphore about webs of belief. A more substantial contrasting proposal is that what justifies our beliefs is ultimately the way in which they hang together or dovetail so as to produce a coherent set. As Davidson puts it, “[w]hat distinguishes a coherence theory is simply the claim that nothing can count as a reason for a belief except another belief” (Davidson, 1986). The fact that our beliefs cohere can establish their truth, even though each individual belief may lack justification entirely if considered in splendid isolation, or so it is thought. Following C. I. Lewis (1946), some proponents think of this situation as analogous to how agreeing testimonies in court can lead to a verdict although each testimony by itself would be insufficient for that purpose.
