Pruss and Rasmussen on Arguments Against a Necessary Being

Many philosophers find the premises of at least some arguments for the existence of a necessary being attractive, but regard the existence of a necessary being either as itself absurd or as having absurd consequences. Pruss and Rasmussen's ninth and final chapter therefore considers a series of six arguments against a necessary being. For the most part, the responses have a common structure. An opponent employs certain principles of logic, epistemology, or semantics connected with possibility and necessity to argue against the existence of a necessary being. Pruss and Rasmussen respond by showing how those same principles can be employed...

Pruss and Rasmussen on Modal Uniformity

Pruss and Rasmussen's sixth chapter is entitled "From Modal Uniformity." Based on the general format of the book, one might have expected a new argument for a necessary being from modal uniformity, but that is not exactly what happens in this chapter. Rather, a principle of modal uniformity is offered in support of the possibility premises employed by the previous arguments. The general idea behind principles of modal uniformity is that certain kinds of differences in propositions look modally irrelevant. That is, we don't expect these differences to lead to a difference in modal status. Pruss and Rasmussen focus on...

Pruss and Rasmussen's Second Argument from Possible Causes

Traditional cosmological arguments typically include a premise about what things have causes or explanations. Modal cosmological arguments rely instead on a premise about what things could have causes or explanations. The aim of Pruss and Rasmussen's fifth chapter is to uncover the weakest/safest/most modest principle about possible causes that can be used to construct a valid modal cosmological argument. They arrive at the following (I retain their numbering): The W Principle: normally, for any property P, if (i) P can begin to be exemplified, (ii) P can have instances that have a cause; (iii) P is basic or a determinate...

Pruss and Rasmussen's First Argument from Possible Causes

Pruss and Rasmussen's fourth chapter discusses what the authors variously describe as a "modal cosmological argument" or "argument from possible causes". Although this type of argument has received some discussion in the recent philosophy of religion literature, it is much less well known than the classical argument from contingency discussed in chapter three, and the dialectic of objections and replies is much less well-worn. The idea behind this kind of argument is that since the modal system S5 defended in chapter two validates the inference from possibly there is a necessary being to there is a necessary being, it suffices...

Pruss and Rasmussen on the Argument from Contingency

Pruss and Rasmussen's third chapter begins the book's main project, the examination of arguments for a necessary being. They describe the argument presented here as "classical," in contrast to the "newer, more sophisticated" arguments they will discuss later (p. 33). The argument they present is indeed pretty similar to versions that would be found in a typical survey of philosophy of religion. However, the discussion of the argument is careful and sophisticated, and it does show how the considerations about modality discussed in chapter 2 can help to improve our understanding of the argument, and in particular to answer some...

Introduction to Pruss and Rasmussen, Necessary Existence

One of my projects this summer is a review of Alexander Pruss and Joshua Rasmussen's Necessary Existence for American Catholic Philosophical Quarterly. I read the book for the first time a few months ago, but I'm now working through it more carefully in preparation for writing the review. I've often found it helpful in the past to write a blog post about each chapter of a book and then condense them into a review, and I'll be doing that here over the next couple of weeks. The project of the book is to investigate arguments for the claim that there...

Two Varieties of Occasionalism

As Elisabeth of Bohemia famously pointed out, Descartes appears to be committed to the following inconsistent triad: In every instance of causation, there is an a priori conceptual connection between cause and effect. There are no conceptual connections between mind and body. Mind and body interact causally. The most common response to this problem among Descartes's 17th century followers was occasionalism, the view that bodily phenomena do not genuinely cause mental phenomena but are merely reliably correlated with them, and vice versa, so that bodily phenomena may be called occasions of mental phenomena and mental phenomena may be called occasions...

A Theological 'Slippery Slope' Argument for Compatibilism

When I first began studying philosophy, I was a convinced libertarian about free will. My reasons included supposed direct introspection together with what I now take to be two distinct but related intuitions, which I will now call the consequence argument intuition and the buck-stopping intuition. (I wouldn't have explained them like this back then, of course: I'm trying to do some autobiographical rational reconstruction.) The consequence argument intuition is the notion that if an event is necessitated—whether logically, metaphysically, or causally/nomologically—by factors outside my control, then that event is itself outside my control, and an event outside my control...

Oppy on Theism, Naturalism, and Explanation

In his contribution to Goldschmidt's The Puzzle of Existence, Graham Oppy argues that, "as [a] hypothes[i]s about the contents of global causal reality" (p. 51), naturalism is ceteris paribus preferable to theism. Oppy's strategy for defending this claim is to consider three hypotheses about the structure of global causal reality, and argue that naturalism is superior to theism on each hypothesis. Here are his three hypotheses: Regress: Causal reality does not have an initial maximal part. That is, it is not the case that there is a part of causal reality which has no parts that stand in causal relations...

Substances, Events, and Causes

Irreducible agent causation is quite a slippery notion. Many philosophers hold that it is not merely slippery, but unintelligible or incoherent. I take it that these philosophers have stated genuine problems which a proponent of irreducible agent causation needs to answer. However, in pressing objections to agent causation, philosophers sometimes make what seem to me to be pretty serious mistakes. First, sometimes they fail to include (explicitly) the qualifier 'irreducible.'* Second, they sometimes claim that the problem (or one of the problems) with agent causation is that it's a species of substance causation, and substance causation is unintelligible or bad...

A Theistic Argument for Compatibilism

One often hears it asserted that most theists are metaphysical libertarians. This seems to be supported, at least in the case of theistic philosophers, by the PhilPapers survey where target faculty specializing in philosophy of religion, who were overwhelmingly more likely to be theists than their peers in other specializations (72.3% for religion specialists vs. 14.6% overall), were also overwhelmingly more likely to be libertarians (57.4% vs. 13.7%). (Unfortunately, there doesn't seem to be a way to compare theists to non-theists across the board, so we just have this correlation among religion specialists.) Now, I suppose there are some reasons...

On Omnipotence

In my last Sobel post, I discussed Sobel's proposal that, since the Stone Paradox shows essential omnipotence to be incoherent, the traditional God, since he would have his properties essentially, would have essential ONSLIP, or only necessarily self-limited power, but that this would not amount to omnipotence. Here I want to propose an alternative account of omnipotence, an attribute worthy of that name and which would be had essentially. First, however, we must distinguish power from freedom. To be omnipotent is to be all powerful. God is also supposed to be free in his exercise of power, and this creates...

A Non-Leibnizian Cosmological Argument

In my last Sobel post, I reconstructed the cosmological argument Sobel attributes to Leibniz in such a way that there was no obvious contradiction in the premises by using Leibniz's own resources. Here I want to try to produce an argument with more widely accepted premises. Recall that Sobel's reconstruction is as follows: (1)The World - the Cosmos - exists. (2) The World is contingent, it is a contingent entity. (3) For everything that exists - for every fact and every existent entity - there is a sufficient reason for its existence. (4) The sufficient reason for the existence of...

Correlation, Causation, and Salvation

The New Testament uses a number of criteria to identify the 'saved' (in this post, I won't be concerned with what exactly 'saved' means, though I will be assuming, somewhat controversially, that its meaning is more or less consistent). For instance, the saved are identified as: Those who 'bear fruit' (Matt. 7:16-20), where this seems to involve undergoing some kind of general change of character (Gal. 5:22-25). Those who perform particular good or loving deeds (Matt. 7:21, 1 John 1:6, 2:3-6), especially care for the poor (Matt. 25:31-46). Those who abstain from particular evil or hateful deeds (1 John 2:9-11)....
