A Genuine Dialectical Problem for Ontological Arguments

Sobel spends much of the third chapter Logic and Theism evaluating the dialectical status of ontological arguments, and, in particular, whether ontological arguers are entitled to the premise that it is possible that there be a perfect being. I am simply going to take the occasion here to state my opinion on the matter. There is a fundamental dialectical tension in the ontological arguments that start from this premise. If, on the one hand, necessary existence follows trivially from the stipulated definition of perfection, then the argument will beg the question as Sobel suggests that Anselm's argument does. That is...

Sobel's Argument Against Believing in the Possibility of a Perfect Being

My previous posts on Sobel's Logic and Theism, have been pretty favorable and made only minor criticisms or qualifications. In this post, my criticism will be much more strenuous for, in his criticism of modern modal ontological arguments, Sobel has made a serious error. Sobel wants to argue that there is no strong presumption in favor of the possibility of a perfect being, and that, because of contrary evidence (e.g. the problem of evil), if the ontological argument is to benefit the theist (by showing that, necessarily, there is a perfect being), rather than harm the theist (by showing that...

The Dialectical Appropriateness of Ontological Arguments

After, for some reason or other, spending some 30 dense pages of Logic and Theism on the laughable ontological arguments of Descartes and Spinoza, Sobel moves on to the more interesting argument advanced by Anselm. (The next chapter deals with versions of the argument set in modern modal logic, such as those of Hartshorne and Plantinga.) In my view, the Descartes and Spinoza arguments don't even look good; the Anselm version at least produces puzzlement, insofar as the reasoning looks valid, yet it seems, intuitively, that no such strong conclusion could ever be derived from such weak premises. Sobel (fairly uncontroversially...

Normative Skepticism and the Existence of God

As I discussed in my last post, Sobel argues that the main requirement anything has to fulfill in order to count as a god is that it must be deserving of worship. However, as Sobel argues on pp. 24-25 of Logic and Theism, this requires that it makes sense to talk about something being worthy or unworthy of worship. An error theory of the normative (a view that questioned whether statements about 'worthiness' and other such things were ever correct), such as the view espoused by J. L. Mackie, would have the result that no matter what might exist in...

Divine Freedom and Worship

This is the first substantive post in my discussion of Sobel's Logic and Theism. The first chapter of Sobel's book focuses on the question of what people disagree about when they disagree about whether God exists. There are a lot of interesting metaphysical and linguistic issues here, like the meaningfulness of negative singular existentials, but this is all really preliminary to the real purpose of evaluating beliefs in God and the reasons for them, so, although these issues are interesting, I'm going to keep discussion of them to a minimum, and focus on what I take to be the first

Sobel's Logic and Theism: An Introduction to my Forthcoming Discussion

Some time ago, I promised that I would take time on this blog to seriously engage with some recent work arguing in favor of atheism. The book chosen, mostly on Brandon's recommendation, was Jordan Howard Sobel's 2003 Logic and Theism: Arguments For and Against Beliefs in God. This summer I had a fairly long reading list of things more closely related to my main research directions in metaphysics and early modern philosophy so, unfortunately, I did not get started on this earlier. I have, however, now (one week before the start of classes) completed my other reading and begun working...

Ignorant Assertions in Pennsylvania

I've just heard that my paper, "In Defense of Ignorant Assertions" will be included in the program of the 64th Mountain-Plains Philosophy Conference, to be held at Washington and Jefferson College in Washington, PA October 15-16. Will any other philosophy bloggers be in attendance?

Quote of the Day: Gutting on Dawkins

Religious believers often accuse argumentative atheists such as Dawkins of being excessively rationalistic, demanding standards of logical and evidential rigor that aren't appropriate in matters of faith. My criticism is just the opposite. Dawkins does not meet the standards of rationality that a topic as important as religion requires. The basic problem is that meeting such standards requires coming to terms with the best available analyses and arguments. This need not mean being capable of contributing to the cutting-edge discussions of contemporary philosophers, but it does require following these discussions and applying them to one's own intellectual problems. Dawkins simply...

More on FWD and Brute Contingencies

Yesterday, I noted that Plantinga's Free Will Defense (FWD), as it appears in The Nature of Necessity (NN) involves some very odd brute contingencies. These brute contingencies are not determined by God, or by anything else at all. They are truly brute: there is no reason or explanation for them. Furthermore, they limit God's power. When Plantinga admits that according to his theory "the power of an omnipotent God [is] limited by the freedom he confers upon his creatures" (NN 190), he cites William Wainwright, "Freedom and Omnipotence", Nous 2 (1968): 293-301. As it turns out, Wainwright is responding to...

Some Odd Brute Contingincies in Plantinga's Free Will Defense

Once upon a time, many philosophers believed that there was a logical problem of evil. That is, it was held that the (obviously true) proposition that there is some evil in the world logically entails that there is no God. (Where God is conceived as omnipotent and perfectly good.) I imagine that a lot of philosophers still believe this, but today few are arguing for it in print. Instead, atheist philosophers now typically put forth an evidentiary problem of evil. That is, they propound an argument something like this: The more evil there is, the less likely it is that...

Two Concepts of Justification

In my comment on Uncommon Priors the other day, I distinguished between two different problems I might need to be saved from: (1) I deserve to be punished for my actions, and (2) if there is a God, he will probably punish me for my actions. These, in my view, are two different problems. That is, the fact that I deserve punishment is a terrible thing in itself, independent of whether I will ever actually be punished. Because of this, we can see our need for salvation, even before we believe in God. This might be important...

Philosophers' Carnival 112

The 112th Philosophers' Carnival is now up at A Concentrated Tincture, with a link to my post on The Lockean Proviso and Federally Managed Lands. Also in the carnival is Paul Gowder's interesting treatment of, as he calls it, "The Difference Between Faith and Fallibilism". I've left a lengthy comment there which may be of interest to some readers of this blog. This is supposed to be the first installment in a series of at least three posts; I am looking forward to reading the rest of what Paul has to say on this subject.

The Lockean Proviso and Federally Managed Lands

On my recent vacation, I visited a number of national parks (specifically: Crater Lake, Redwood, and Yosemite). This got me thinking about the moral and political aspects of federal land management, including the National Park System. Libertarians are often skeptical of government ownership of anything. However, in this post I want to argue that the Lockean Proviso actually demands such a system of government land management, and so such a system should be supported by libertarians of the Nozickian/Neo-Lockean sort, such as myself. Let's start at the beginning. Locke holds that initially all of earth's natural resources were held in...
