Faith and Rationality

In my previous post on Sobel's treatment of Pascalian wagers, I indicated that, although I accept a strong thesis about the autonomy of theoretical reason, I believe that religious faith has more to do with practical than with theoretical reason. Now, faith can have as its object either a person or a proposition. (There are also other uses, like having faith in a theory, but I take these two to be the central ones.) Call the former faith-in (as in, 'I have faith in you') and the latter faith-that (as in, 'I have faith that everything will turn out alright')....

Sobel on Pascalian Wagers

In the 13th and final chapter of his book, Sobel discusses Pascalian wagers. According to Sobel, there need not be anything wrong with the practical reasoning involved in a Pascalian wager. In addition to defending this controversial claim, Sobel must explain how, if the Pascalian reasoning is correct, he can be justified in holding on to his atheism. As the chapter unfolds, both contentions are defended as a package. In general, for reasons to be explained below, I disagree with Sobel's approach here. However, I do agree with him on one thing: religious faith is more a matter of practical...

Sometimes It's Rational to Act Arbitrarily

In the middle sections of his 12th chapter, Sobel goes through a series of adjustments to his deductive argument from evil designed to get around various versions of the Free Will Defense and other tactics attempted by theists. For reasons mentioned earlier, I am not happy with Sobel's formal treatment of these arguments, so I'm going to reconstruct the substance of the argument somewhat differently. Consider the following: If there were a perfect being, it would take a best course of action available to it in creating the world If a perfect being took the best course of action available...

Kantian Ethics Simplified

It is probably a safe bet that no view which has ever been successfully explained in a blog post can correctly be attributed to Kant. I won't try to falsify that claim in this post. What I will try to do is to present a sketch of a simple (probably too simple) moral theory that shows why I find Kantian ethics attractive. The fundamental principle of this ethical theory is the following definition: Wrongness =df. the property an action has iff it is the direct result of a practical judgment whereby the agent is committed to a practical contradiction. An...

Morality as a System of Assertoric Imperatives

I recently read Philippa Foot's paper "Morality as a System of Hypothetical Imperatives" for an ethics class. The paper, as the name suggests, puts forward the view (which Foot has since rejected) that the imperatives of morality are merely hypothetical and not, as Kant had argued, categorical. What this means is that morality tells us how we should act if we want certain things, such as justice and the general happiness of humanity. As Foot recognizes, an untoward consequence of this view is that, if it is true, we can't sensibly tell people that they should want justice or the...

Preventing Terrorism "At All Costs"

Insofar as there is any debate about airline security measures at all (and there is not as much as there should be), the debate typically assumes that we ought to prevent terrorism "at all costs". But this is simply false. Last night I saw a segment on the local news here in Johnstown, PA, where a "terrorism expert" (it wasn't clear exactly what his qualifications were) said that we could catch terrorists much more effectively by engaging in religious profiling. Apparently a federal legislator recently said the same thing. What these people are pointing out is something that should be...
