Here's the abstract:

Abstract:William  Lane  Craig’s  much–discussed kalamcosmological argument for God’s existence is intended to provide support for a particular theistic  explanation  of  the  origin  of  the  universe.I argue here that Craig’s theistic  account  of  the  origin  of the  universe entails  two  contradictions  and hence   should   be   rejected.The   main   contribution   of   the   paper   is   the identification     of     some     relatively     straightforward     but     previously unrecognized problems in Craig’s hypothesis that the beginning of the universe was a temporal effect of a timeless personal cause.

Fantastic Recent Paper on Pragmatic Encroachment and Religious Experience

I've been waiting for about 10 years for someone to carefully lay out the argument in the following paper, and my wait is now over:

Gillham, Alex X. "Religious Experience, Pragmatic Encroachment, and Justified Belief in God", Open Theology 1:6 (2020): 296-305

Here's the abstract:

The secondary literature on religious epistemology has focused extensively on whether religious experience can provide evidence for God’s existence. In this article, I suppose that religious experience can do this, but I consider whether it can provide adequate evidence for justified belief in God. I argue that it can. This requires a couple of moves. First, I consider the threshold problem for evidentialism and explain pragmatic encroachment (PE) as a solution to it. Second, I argue that religious experience can justify belief in God if one adopts PE, but this poses a dilemma for the defender of the veridicality of religious experience. If PE is true, then whether S has a justified belief in God on the basis of religious experience depends on how high the stakes are for having an experience with God. This requires one to determine whether the stakes are high or low for experiencing God, which puts the experient of God in an awkward position. If the stakes are not high, then justified belief in God on the basis of religious experience will be easier to come by, but this requires conceding that experiencing God is not that important. If the stakes are high, then the experient can maintain the importance of experience with God but must concede that justified belief in God on the basis of experience with God is less likely to happen, perhaps impossible.

Add this one to the list.

Negative PSR and Naturalism

(Rough Draft)

Spinoza appealed to a version of PSR that has both a positive and negative component:

Spinoza's Principle of Sufficient Reason (PSR): every fact that obtains has a complete explanation for why it obtains, and every fact that fails to obtain has a complete explanation for why it fails to obtain. 

Suppose you accept Spinoza's PSR. Then you have a reason to think that every possible world is, and must be, actual. Otherwise, you will be hard pressed to find an explanation for why some possibilities fail to obtain. But if so, then there is an under-appreciated rational explanation for why the universe exists, rather than nothing. It is also an under-appreciated rational explanation for why our universe exists, rather than another. In this way, Spinoza's PSR provides the materials for a cosmological argument for naturalism.

Here is one way to exploit Spinoza's PSR to argue for naturalism. According to L.A. Paul's one-category ontology, there is just one kind of thing: qualities (i.e., properties). Qualities are universals -- i.e., repeatable entities -- that (arguably) exist necessarily and a se, and have a nature closer to Aristotle's immanent (non-substantial) forms than Plato's transcendent forms (there are no uninstantiated qualities). All the rest of reality is ultimately explained in terms of mereological fusions of n-adic qualities.[1] The fusion relation is a composition relation, and so derivative entities are composed of basic qualities.[2] The resultant picture is mereological bundle theory:

On my view, matter, concrete objects, abstract objects, and perhaps even spacetime are constructed from mereological fusions of qualities, so the world is simply a vast mixture of qualities, including polyadic properties (i.e., relations). This means that everything there is, including concrete objects like persons or stars, is a quality, a qualitative fusion, or a portion of the extended qualitative fusion that is the world-whole. I call my view mereological bundle theory. (Paul, "A One Category Ontology", p. 2)

According to mereological bundle theory, the world (here, I need not confine myself to the physical world, so by ‘‘world’’ I mean the whole world, not just the cosmos) is a vast mixture of properties, some with a single location (whether in configuration space, or in spacetime, or in something else), some with many locations, some located everywhere, and perhaps even some without any location at all (Locations are defined by n-adic properties. For simplicity, take the fundamental space to be relational, and define up ‘‘points’’ in the space using these relations and properties). The world is constructed from arrangements of properties and relations that are fused together to make things of all sorts: concrete objects, abstract objects, events, states of affairs, facts, fields, regions, and anything else there is. So, according to the mereological bundle theorist, fields, particles, entangled systems of particles, spaces, molecules, cells, bodies, persons and societies are all constructed, most fundamentally, from fusions of properties and relations. (Paul, "Building the World From Its Fundamental Constituents", p. 242).

Paul's one category ontology provides a nice an ontological framework for contemporary physics:

...consider the wave-function realist who takes the world-whole to be a wavefunction. On the GRW theory of the world, the world is a universal wave function that evolves in accordance with the dynamical laws. Understood in terms of mereological bundle theory, the wavefunction is the fusion of amplitude and phase properties (along with any other properties of the system) with structuring properties or relations, including the structuring relations described by Schrodinger’s equation and by the collapse postulate. A variant of this view can fit the Everettian approach, and one can also fit David Albert’s (1996) treatment of Bohmian mechanics by adding a world-particle that is simply a fusion of properties to the plurality of things. (Ibid., p. 254).

I think a naturalist who adopts Paul's one-category ontology can exploit her account to explain the existence and fine-tuning of our universe. To start, consider that if we assume with Paul that the world-whole is just the sum of all qualities, and they can combine in various ways in accordance with the constraints of their intrinsic natures, what prevents them from combining in every possible such way? It would be mysterious why they fuse/bundle in some ways and not others if they didn't fuse/bundle in every way consistent with their natures. Paul's one-category ontology thus naturally generates pressure to accept a mereology-focused variant of Spinoza's negative PSR:

Negative Mereological PSR (NMPSR): a given plurality of qualities will fuse/bundle unless there is a sufficient reason for why they do not.

Given NMPSR, then, we should assume that all possible bundles/fusions exist in the world-whole. If so, then we can explain everything the theist wants explained: 

Why does anything exist? Because qualities exist and they're necessary beings that exist a se

Why does a universe exist? Because (as we know from our observations of the actual world) there is a compossible distribution of qualities in some "region" of the world-whole that comprises a universe. So by that fact and NMPSR, there is a presumption to think that it is inevitable that there is a fusion/bundle of those properties -- i.e., a mereological fusion of qualities that make up a configuration space, along with a fusion of phase and amplitude properties, that compose a universal wavefunction. From non-spatiotemporal property configurations like this, you necessarily get spatiotemporal universes that logically supervene upon them.[3]  

Why does this universe exist? By NMPSR, absent a good reason to think otherwise, we should assume all possible universe quality fusions exist inevitably and necessarily within the world-whole of qualities, and this is one of them.[4]

To circle back to the original point: Spinoza has been making a comeback in recent decades in the study of early modern philosophy. His negative PSR is at least one reason why philosophers of religion should celebrate this.

-------------------------------

[1] On Paul's account, the relation of mereological bundling here is not a fundamentally spatiotemporal one of spatiotemporal parts composing a spatiotemporal whole. This is because contemporary physics seems to have shown that spacetime isn't fundamental (think, for example, of wave function realism with respect to quantum mechanics, theories of quantum gravity that take spacetime to be emergent, etc.).

[2] Question: How does a quality become spatiotemporally localized on Paul's view? Answer: By bundling with spatiotemporal properties/relations: "Objects may have their locations in virtue of being fused with whatever location properties and relations there are that define the actual space of the world, and many objects will have a physical structure in virtue of having location properties and relations as parts of their fusions, or in virtue of being part of a larger fusion which has location properties and relations as parts. The character of the space might not be what we take the character of ordinary spacetime to be, but the structure of the space is generated by fusing qualitative properties with relevant properties and relations that define the space as determined by modern physics. Hence, the view is consistent with (and explicitly accommodating of) various approaches in modern physics: it is friendly to structuralism, and is perfectly consistent with realist interpretations of the ontology of quantum mechanics, for example, with realism about the wavefunction." (Paul, Building the World From Its Fundamental Constituents", p. 242).

[3] As Paul points out, her one-category ontology is compatible with a parts-to-whole mosaic, as well as a holistic whole-to-parts picture. She prefers the latter because it's a better fit with with quantum holism/entanglement phenomena.

[4] We might not even have to appeal to NMPSR here. For there are good grounds for thinking Everettian QM (EQM) is true, and as Alastair Wilson points out, EQM allows for different fundamental parameters within the universal wavefunction (indeed, it allows for all possible parameter variations). If so, then (given this fact plus the decoherence mechanism of EQM) EQM can generate something akin to a level-5 multiverse, where every possible universe exists in some branch or other of the universal wavefunction. 

A New Version of the Problem of Natural Evil

 (Rough draft)

Here's yet another argument to add to the list. It will take me some time to flesh it out properly, but the argument is a version of the problem of natural evil. The version I have in mind appeals to system 1 and system 2 of dual process theory in cognitive psychology, but I think a similar line of argument would go through on other accounts of cognitive systems. The core idea is that: (i) a significant portion of the population is destined, beyond factors it cannot control, to fail to reliably avail itself of system 2 reasoning (or to defer to those who can); (ii) this reliably leads to large quantities of suffering to both groups of people; (iii) (i) and (ii) are surprising on theism, but not on naturalism; therefore, (iv) such data provide at least some evidence for naturalism vis-a-vis theism.


Malpass' New Paper Critiquing the Argument from Logic

Malpass, Alex. "Problems for the Argument from Logic: a Response to the Lord of Non-Contradiction", Sophia (forthcoming)

Here's the abstract:

James Anderson and Greg Welty have resurrected an argument for God’s existence (Anderson and Welty 2011), which we will call the argument from logic. We present three lines of response against the argument, involving the notion of necessity involved, the notion of intentionality involved, and then we pose a dilemma for divine conceptualism. We conclude that the argument faces substantial problems.
