A friend of mine suggested that coherentalist theory of justification is more appropriate than foundationalism when applied to religion. On the other hand foundationalism is superior when applied to the empirical world. However he couldn't justify his proposition. It made me wonder, how one to choose between two theories of justifications, especially the two mentioned above? Does one theory must be wrong, for the other to be correct? Or are there degrees of efficiency or truth conductiveness, through which we can compare them?
