Blogging Through Smith's Naturalism and our Knowledge of Reality

I'll be blogging through R. Scott Smith's Naturalism and Our Knowledge of Reality for a bit. The aim is not to thoroughly exposit the ins and outs of each chapter, but to briefly summarize a chapter per post, and to take up a key point or argument in each one. To start off, though, I should offer a bird's eye view of the book. 

In this ambitious book, R. Scott Smith aims to show that philosophical naturalists can’t account for our knowledge of the world. In particular, philosophical naturalism lacks the ontological resources to account for direct access to the external world, accurate concept formation of entities within the external world, and genuine intentionality, which in turn (argues Smith) are necessary conditions for the possibility of knowledge. 

We can summarize Smith’s core argument as follows:

1. If naturalism is true and we can have knowledge of the external world, then such knowledge can be adequately accounted for in terms of the naturalist’s ontology.
2. We can have knowledge of the external world.
3. Knowledge of the external world can’t be adequately accounted for in terms of the naturalist’s ontology.
4. Therefore, naturalism is false.

(1) looks to be something on the order of an analytic truth, and (2) will only be rejected by radical skeptics. The bulk of Smith’s book is therefore devoted to supporting (3). His strategy is to explicate and critique a sufficiently representative sampling of naturalistic accounts of some necessary prerequisites for knowledge (esp. those listed above), and to argue that each such account is deeply inadequate. The book ends with a brief defense of Christian theism and some supposed implications for public policy.

Here are two initial comments. First, very little time is given to characterizing and clarifying the notion of naturalism at issue. In fact, the first and perhaps most detailed characterization of naturalism is found in a footnote in the Introduction. There is also no index entry for the term. This is surprising and puzzling, given that the book is 
a sustained critique of naturalism.

Second, the brief characterization of naturalism Smith does offer suggests that the primary aim of his critique is not naturalism proper, but rather physicalism. Here is the characterization he offers in footnote 1 of the Introduction:
Though we will see nuances and variations in the naturalists' works that follow, very roughly I take philosophical naturalism to be a thesis that reality consists solely of the physical, spatiotemporal world; thus there are no supernatural or nonnatural entities or beings. From that stance surface epistemological, moral, and other positions.
One might raise worries about obscurity and circularity in this definition, but I will leave these concerns aside for now. Here I just want to point out that there are many versions of naturalism, including many that are incompatible with the characterization offered by Smith. And because of this, the claim that
(i) The physicalist's ontology lacks adequate ontological resources for the possibility of knowledge.
is compatible with
(ii) The naturalist's ontology has adequate ontological resources for the possibility of knowledge.
To put it another way, my second worry is that Smith's case commits (what I have elsewhere called) the Common Apologetic Fallacy.

Epicurean Cosmological Arguments for Matter's Necessity

One can find, through the writings of Lucretius, a powerful yet simple Epicurean argument for matter's (factual or metaphysical) necessity. In simplest terms, the argument is that since matter exists, and since nothing can come from nothing, matter is eternal and uncreated, and is therefore at least a factually necessary being. 
A stronger version of Epicurus' core argument can be developed by adding an appeal to something in the neighborhood of origin essentialism. The basic line of reasoning here is that being uncreated is an essential property of matter, and thus that the matter at the actual world is essentially uncreated.
Yet stronger versions of the argument could go on from there by appealing to the principle of sufficient reason to argue that whatever plays the role of being eternal and essentially uncreated does not vary from world to world, and thus that matter is a metaphysically necessary being.
It seems to me that this broadly Epicurean line of reasoning is a co…

Notes on Mackie's "Evil and Omnipotence"

0. Introduction
0.1 Mackie argues that the problem of evil proves that either no god exists, or at least that the god of Orthodox Judaism, Christianity, and Islam, does not exist. His argument is roughly the same version of the problem of evil that we’ve been considering.
0.2 Mackie thinks that one can avoid the conclusion that God does not exist only if one admits that either God is not omnipotent (i.e., not all-powerful), or that God is not perfectly good. 0.3 However, he thinks that hardly anyone will be willing to take this route. For doing so leaves one with a conception of a god that isn’t worthy of worship, and therefore not religiously significant.
0.4 After his brief discussion of his version of the problem of evil, he considers most of the main responses to the problem of evil, and concludes that none of them work.

1. First Response and Mackie's Reply
1.1 Response: Good can’t exist without evil; evil is a necessary counterpart to good.
1.2 Mackie’s reply:
1.2.1 this see…

Notes on Swinburne, "On Why God Allows Evil"

Notes on Swinburne’s “Why God Allows Evil”

1. The kinds of goods a theistic god would provide: deeper goods than just “thrills of pleasure and times of contentment” (p. 90). For example:
1.1 Significant freedom and responsibility
1.1.1 for ourselves
1.1.2 for others
1.1.3 for the world in which they live
1.2 Valuable lives
1.2.1 being of significant use to ourselves
1.2.2 being of significant use to each other

2. Kinds of evil
2.1 Moral evil: all the evil caused or permitted by human beings, whether intentionally or through negligence (e.g., murder, theft, etc.)
2.2 Natural evil: all the rest: evil not caused or permitted by human beings (e.g., suffering caused by hurricanes, forest fires, diseases, animal suffering, etc.)

3. The gist of Swinburne’s answer to the problem of evil: God cannot – logically cannot -- give us the goods of significant freedom, responsibility and usefulness without thereby allowing for the possibility of lots of moral and natural evil. This is why he has al…
