There are Lots of Arguments Against Theism That Don't Reduce to the Problem of Evil

Rough draft:

Forget the god of classical theism for a moment. Consider instead the hypothesis that there is a being who is omnipotent and omniscient, yet morally indifferent, and who is reliable at achieving their goals. Call this view blahtheism. Suppose further that we add to blahtheism the hypothesis that such a god is interested in creating a hospitable environment for humans (suppose they have a goal  to be reliable in creating and conserving communities of humans in the way the some build and maintain ant farms). What would you then expect Earth to be like? The answer is simple: one that is hospitable to human life. Therefore, the datum that the Earth is inhospitable to humans is surprising on blatheism. By contrast, a human-inhospitable environment is not surprising on naturalism, since on that hypothesis, life on Earth is shaped solely by evolutionary factors, shaping the world into a hostile place, due to the competition for scarce resources. Therefore, the datum that the Earth is a human-inhospitable environment provides at least some confirming evidence for naturalism vis-a-vis blahtheism.

The point of this exercise isn't just to call attention to a piece of disconfirming evidence against blatheism; it is rather to point out that at least some data that supports naturalism vis-a-vis supernaturalistic hypotheses does not reduce to the problem of evil. Evil doesn't play a role one way or the other in the argument above; rather, (i) facts about rational omniscience and omnipotence, plus (ii) facts about the god's interests/aims, and (iii) facts suggesting the aims were not achieved, sufficed to generate the problem. This was highlighted by the fact that the blatheistic hypothesis excludes moral properties from the divine nature, and yet we could make reasonable predictions about what such a being would do, given certain intentions. The salient facts here were facts suggesting an aim/outcome mismatch between God's intentions and the world. 

I will go further. I'm betting that other lines of evidence for naturalism (see, e.g., many arguments on this list) seem to have the same feature, viz., their evidential force turns on aim/outcome mismatches of various sorts that don't essentially appeal to God's love or moral perfection (although of course I don't mean to imply that all other arguments against theism besides evil rely on aim/outcome mismatches).

The moral is that the widely held assumption that most arguments against theism reduce to the problem of evil is false.

The Argument from Autonomy Against Theism

Rough draft:

On another occasion, we noted Kahane's excellent (2011) paper, "Should We Want God to Exist?" (PPR 82(3): 674-696). The paper suggests a data point that can be transformed into an argument against the hypothesis of classical theism. 

The sort of argument I have in mind can be gleaned from the following passages:
“Imagine that instead of growing up to become an independent adult, you would forever remain a child, forever under the protection of wise and loving parents. Or imagine living in a land ruled by a benevolent monarch who, although keeping constant watch over everything his subjects do, grants them extensive liberties. These counterfactual worlds would be better, even much better, in various respects. Yet few of us, I believe, would prefer them to the way things actually are, however imperfect. The anti-theist believes we should make a similar choice.”
“The thought is that in a world where complete privacy is impossible, where one is subordinated to a superior being, certain kinds of life plans, aspirations, and projects cannot make sense. I suspect that certain actual life plans, aspirations, and projects that revolve around these values do not make sense, if the world is like that. (Compare: many life plans are incompatible with childhood. If it becomes clear that, contrary to appearance, there is no escape from childhood, then many lives would become absurd and pointless. And discovering that this childhood is eternal would make things worse, not better. As Williams reminds us, immortality is useless if one’s life has no meaning.) Theists sometimes claim that if God does not exist, life has no meaning. I am now suggesting that if God does exist, the life of at least some would lose its meaning. 
Of course this outcome wouldn’t be averted if God were to hide Himself—say if He were to hide Himself only from those who would, in this way, be most grievously hurt by His existence. This wouldn’t help. It would only give these persons the illusion that certain values can be realized—that their lives have meaning.”
It would take much more work to properly develop and defend the argument, but briefly, the way I have in mind to use his core point here as evidence against theism is as follows. If autonomy is required for the flourishing of properly functioning adult humans, then being a subordinate who lacks privacy to even their own thoughts is contrary to the flourishing of mature, properly functioning adult humans, in which case beings made for autonomy of this sort is prima facie surprising on theism. For one would expect God to create beings that are capable of flourishing within his universe.

By contrast, the existence of beings with a prima facie rational and fitting desire for autonomy of this sort is not surprising on naturalism, since on that hypothesis, there is no such being to which we are subordinate. Rather, evolution selected for a preference structure that desires this sort of autonomy -- an autonomy that's compatible with interdependence with similar creatures, but which favors using one's own judgement for navigating our way through life when (e.g.) the wisdom of others seems wrong. Beings with a natural desire or preference of this sort would seem to have an evolutionary advantage over those that do not, since the wisdom of the group might go wrong in ways that are contrary to their survival and reproduction. Therefore, the existence of a prima facie rational and fitting preference for this kind of autonomy provides at least some confirming evidence for naturalism vis-a-vis theism.

100 (or so) Arguments for Atheism

A popular view in contemporary analytic philosophy of religion is that while there are many arguments for theism -- cosmological, ontological, and teleological arguments; moral arguments; arguments from consciousness; etc. (by Plantinga's lights, two dozen or so) -- there are only one or two arguments for atheism, viz., the problem of evil and (more recently) the argument from divine hiddenness.

Helen De Cruz's Excellent Recent Work in Philosophy of Religion

On numerous occasions, we've noted Helen De Cruz's terrific work in philosophy of religion. Here I'd like to provide an update with some recent examples (if you haven't seen them already):

Religious Disagreement (Cambridge University Press, 2018).

"Religious conversion, transformative experience, and disagreement", Philosophia Christi, 20(1) (2018): 265 - 275.

"Etiological challenges to religious practices". American Philosophical Quarterly, 55 (4): 329 - 340.

These papers and many others can be found at her academic webpage. Check them out!

The Argument from Cognitive Biases

There is a lot of data indicating that human minds are riddled with cognitive biases that regularly distort our thinking. This is surprising on the hypothesis of theism, as one would expect such a god to design our cognitive faculties so as to reliably track the truth. By contrast, such data is expected on the hypothesis of naturalism, for then one would expect evolutionary pressures to produce haphazard, makeshift cognitive faculties that track the truth enough to ensure the ability to survive and reproduce, but not much more. The data of cognitive biases therefore provides at least some confirming evidence in favor of naturalism vis-a-vis theism.

UPDATE: I recently learned that Aron Lucas gave this argument in 2018

Kraay's New Paper on Divine Satisficing

On other occasions, we noted Klaas Kraay's important paper on divine satisfying, as well as Chris Tucker's important reply. Kraay's rejoinder, "Is Motivated Submaximization Good Enough for God?" is now out with Religious Studies. Here's the abstract:
In a recent article (Kraay 2013), I argued that some prominent responses to two important arguments for atheism invoke divine satisficing – and that the coherence and propriety of this notion have not been established. Chris Tucker (2016) agrees with my evaluation of divine satisficing, but disagrees with my exegesis of these responses. He argues that they should be understood as invoking motivated submaximization instead. After reviewing the dialectical situation to date, I assess whether motivated submaximization can be deployed in such a way as to defeat these arguments for atheism. I argue that it's far from clear that it can.
