I want to offer a brief reflection on a phenomenon I see often which strikes me as curious; namely, the phenomenon of easing your way into a worldview by piecemeal steps.
In certain religious traditions (most commonly in those traditions typically referred to derogatorily as ‘cults’), there is a proselytic strategy of conveying certain articles of the faith (which may seem intuitive, wholesome, or otherwise welcome) but keeping information about other articles of faith hidden or secret except to the appropriately initiated. Underlying this practice is this unarticulated recognition that several of that religion’s teachings are so outlandish and counterintuitive that to even admit them in public (or in the presence of the uninitiated) would do damage to the cause of winning people over to their faith. As slimy as I’m inclined to think this practice is, there is perhaps something shrewd about it in light of the way most of us form our worldview-sized beliefs. In fact, it may be the case that for most major worldviews (worldviews which, in the free marketplace of ideas, do exceptionally well at winning over a great portion of the human race) people naturally ease their way into them by finding good reasons to affirm them and then making counter-intuitive adjustments along the way to accommodate them. We can illustrate this, in my submission, even by taking a critical look at metaphysical naturalism.
Take naturalism to be, approximately, the belief that (i) ‘God exists’ is not true, (ii) there exist at least some of the theoretical entities postulated by our best science, and (iii) that there exist no entities belief in which cannot be motivated in principle by a scientific view of the world (with the possible exception of God, caveat in casu necessitas). Perhaps naturalism sounds prima facie plausible to many people; the tremendous success of the scientific project of making sense of the world, the apparent superiority of scientific explanations over pre-scientific explanations, the relative implausibility of worldviews competing with naturalism given our new scientifically updated background knowledge about the world, all seem to lend some credence to metaphysical naturalism. One might be led, for these reasons, to adopt a naturalistic worldview and then slowly adjust their auxiliary beliefs accordingly one at a time. First, they may give up robust (or at least traditional) moral realism. Second, they may give up on affirming that there are objectively true (in the correspondence sense) mathematical propositions, or even analytic ones.1 Next they may give up correspondence theory, and then finally they end up denying things like qualia and conscious states.2 Before too long the naturalist will go from sounding soberingly sane to talking about “the illusion that thought is about stuff,”3 and insisting that there are no true sentences (including this one). The conclusions to which one arrives end up being so obnoxious to common sense, so ludicrous to the man on the street, that no sane person could ever agree to them without being eased into accepting them one small step at a time. Just as the frog who remains in slowly warming water until it boils her alive, so too the stubborn naturalist complacently gives in, incrementally, to ostensible insanity; the more comprehensive the atheist’s guide to reality gets, the more it looks like a guide to the surreal.
The very same happens with (some popular versions of) fundamentalism; one begins by finding the Christian worldview plausible for a variety of reasons ranging, perhaps, from natural theology to historical biblical scholarship, from cute arguments (like C.S. Lewis’ trilemma)4 to (Josh McDowell’s)5 systematic apologetics. However, before long one is arguing that the light of supernovae, which has taken millions of years to reach us, was created by God merely a few thousand years ago in order to create the appearance of now-dead stars, or that cancer exists because a talking snake fooled our most primitive human ancestor, or that carbon-dating is so inaccurate that it doesn’t preclude the possibility that dinosaurs were roughly contemporaneous with mankind. In this manner one slides from apparently reasonable starting points to what may as well be Alice’s wonderland.
A similar pattern holds true for lone-wolf thinkers whose worldviews end up being hodge-podge syntheses which hardly anyone else will ever find plausible or intellectually satisfying. Original thinkers from Zeno to Berkeley, from Diogenes to David Lewis put forward philosophies regarded by most to be laughable grandiloquent fictions. It is not surprising, then, that so many should regard the history of philosophy as a museum of the absurd. Even the man who abandons philosophical inquiry altogether creates for himself a view of the world riddled with inconsistencies and idiocies to which he remains blind thanks only to his refusal to reflect critically upon them.
Given this situation, it seems reasonable to ask: is there any stopping the flood of myriad derisory beliefs? The question of how plausible a worldview is seems irrelevant to the assessment of its truth unless the presumption that reality is not too counterintuitive turns out to be correct. If reality turns out to be massively counter-intuitive, then plausibility provides no guide to truth. However, if plausibility is the primary litmus test for believability (after logical coherence, etc.), then we are proverbially up the faecal creek without a paddle.
My reaction to this line of thought is as follows; just as parsimony should be regarded as a signpost of truth in the sense that between any two views, ceteris paribus, the more parsimonious is more likely to be true, so closer alignment with common sense makes a view, ceteris paribus, more likely to be correct. What qualifies as common sense may not be so easily answered, but something like nearly universally shared intuitions about plausibility will qualify (we can leave the details to be worked out elsewhere). Obviously most people are prejudiced, to some degree, in advance of the following exercise, but I think one of the most valuable procedures when it comes to worldview-selection is to take inventory of a (prima facie sufficiently plausible) worldview’s most counter-intuitive consequences and compare them to the most counter-intuitive consequences of competing worldviews. This exercise won’t provide us the means for any definitive doxastic adjudication, but I think it remains one of the best approaches we have to comparing competing worldviews.
The alternative, realistically, is for us to unreflectively slide comfortably into a worldview by taking incremental steps towards the absurd, readjusting our plausibility assignments slowly and surely, and ending up with beliefs we would never have consented to accept had we seen clearly precisely to what it was we were inevitably committing ourselves when we adopted the overarching paradigm in question.
