 Note that conservatives need not say that any of the beliefs we have are infallible or incapable of being undermined. Indeed, they might be quite open to the fallibilist thought that our current justified beliefs can be defeated (either rebutted or undercut) by new evidence. So the view doesn't promote belief that is “dogmatic” or “conservative”in some disparaging sense: it says merely that some beliefs that we have, or some “impelling” beliefs, needn't be based on positive evidential (or practical) support in order to be justified (Harman 1986, Lycan 1988, Chisholm 1989, McGrath 2007).
