Testimony and Theistic Belief

Jon Robson
I am a teaching associate at the University of Nottingham. I work on the epistemology of aesthetic, ethical, and religious judgements (and also on videogames).

I hereby assert that God exists and that I am in the fortunate position of knowing this to be the case. Of course I am aware that these assertions are likely to prove ever so slightly controversial (indeed Anna Ichino's previous post raises some insightful and thought-provoking worries about whether I am even correct in thinking that I believe these things) but let’s assume for the time being that they are correct. Furthermore, let’s suppose that you don’t share this knowledge. What, then, can I do to bring you to a position where you too know that God exists?

One obvious suggestion is that I provide you with some cogent argument demonstrating God’s existence. Debates concerning the epistemic status of theistic belief have traditionally centred around the evidential value of such arguments with numerous works discussing religious epistemology focusing exclusively on theistic (and anti-theistic) arguments and a number of philosophers endorsing claims to the effect that the rationality of theistic belief stands or falls with the success of these arguments.

Recently, though, (thanks in no small part to pioneering work by the likes of William Alston and Alvin Plantinga) the focus of discussions in religious epistemology has now widened significantly to include putatively non-inferential justifications for theistic belief arising from certain perceptual (or quasi-perceptual) experiences of the kind discussed in Joshua Cockayne’s recent post. But what if I am unable (or unwilling) to furnish you with arguments or experiences of the relevant kinds? Is there anything else I can do to enable you to know that God exists? Here is one simple suggestion; I do what I have done in the first sentence of this paper. I merely tell you – without argument or additional evidence of any kind – that God exists. In other words I attempt to bring it about that you know that God exists on the basis of my testimony alone.

In my view anyone who believes that we can have knowledge of God’s existence should accept the further claim that we can acquire such knowledge on the basis of testimony; knowledge – whether of God or of more mundane matters – is essentially social. In most areas this claim is now pretty much a commonplace and (folk wisdom about ‘believing half of what you see and none of what you hear’ notwithstanding) most philosophers are happy to accept that testimony is a vital and indispensable source of knowledge. There are, however, still those who argue that there are some domains – aesthetics, ethics, mathematics or (most relevantly for our purposes) religious belief – which serve as exceptions to this general trend. I think these philosophers (often referred to as ‘pessimists’) are wrong across the board.

While a blog post isn’t the place to launch into a full-fledged defence of the claim that testimony can serve as a source of theistic knowledge (or of knowledge in the other areas listed above) I want to briefly discuss one reason for being pessimistic about the success of the pessimist’s project. In my view the prima facie plausibility which pessimism in various domains possesses is often the result of arguments that conflate the absence of knowledge (or of legitimate belief) with the absence of some other valuable aspect(s) of the relevant practice. It is true for example that a person who based their religious beliefs on testimony alone would – again, assuming that theism is true – miss out on much of value possessed by a fellow believer who comes to belief on the basis of a genuinely revelatory and life-changing religious experience (though it’s worth noting that the same applies to someone who comes to believe on the basis of a cogent argument).

And, of course, there is much more to genuine religious commitment than mere propositional belief (as previous posts from Anna and Joshua highlight). Full-blooded religious practice will typically involve all manner of affective, practical, and interpersonal aspects that just don’t seem to be the kind of thing we can acquire (at least in any straightforward way) via testimony. None of this shows, though, that there is anything remotely problematic in forming theistic belief on the basis of testimony. Perhaps these additional elements of religious commitment are not available via testimony alone but there is no barrier to prevent the person who initially forms their beliefs on the basis of testimony from going on to acquire them. Indeed having the correct propositional beliefs, whether by testimony or otherwise, would surely be a help rather than a hindrance to this endeavour.

Delusions in the DSM 5

This post is by Lisa Bortolotti. How has the definition of delusions changed in the DSM 5? Here are some first impressions. In the DSM-IV (Glossary) delusions were defined as follows: Delusion. A false belief based on incorrect inference about external reality that is firmly sustained despite what almost everyone else believes and despite what constitutes incontrovertible and obvious proof or evidence to the contrary. The belief is not one ordinarily accepted by other members of the person's culture or subculture (e.g., it is not an article of religious faith). When a false belief involves a value judgment, it is regarded as a delusion only when the judgment is so extreme as to defy credibility.

Rationalization: Why your intelligence, vigilance and expertise probably don't protect you

Today's post is by Jonathan Ellis , Associate Professor of Philosophy and Director of the Center for Public Philosophy at the University of California, Santa Cruz, and Eric Schwitzgebel , Professor of Philosophy at the University of California, Riverside. This is the first in a two-part contribution on their paper "Rationalization in Moral and Philosophical thought" in Moral Inferences , eds. J. F. Bonnefon and B. Trémolière (Psychology Press, 2017). We’ve all been there. You’re arguing with someone – about politics, or a policy at work, or about whose turn it is to do the dishes – and they keep finding all kinds of self-serving justifications for their view. When one of their arguments is defeated, rather than rethinking their position they just leap to another argument, then maybe another. They’re rationalizing –coming up with convenient defenses for what they want to believe, rather than responding even-handedly to the points you're making. Yo

A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind

Today's post is by  Karen Yan (National Yang Ming Chiao Tung University) on her recent paper (co-authored with Chuan-Ya Liao), " A co-citation analysis of cross-disciplinarity in the empirically-informed philosophy of mind " ( Synthese 2023). Karen Yan What drives us to write this paper is our curiosity about what it means when philosophers of mind claim their works are informed by empirical evidence and how to assess this quality of empirically-informedness. Building on Knobe’s (2015) quantitative metaphilosophical analyses of empirically-informed philosophy of mind (EIPM), we investigated further how empirically-informed philosophers rely on empirical research and what metaphilosophical lessons to draw from our empirical results.  We utilize scientometric tools and categorization analysis to provide an empirically reliable description of EIPM. Our methodological novelty lies in integrating the co-citation analysis tool with the conceptual resources from the philosoph
