A message scribbled irreverently on the mediaeval walls of the Nonberg cloister says this: ‘Neither of us can go to heaven unless the other gets in.’ It suggests an argument against the view that those who love people who suffer in hell can be perfectly happy, or even free from all suffering, in heaven. This paper considers the challenge posed by this thought to the coherence of the traditional Christian doctrine on which there are some people in hell who are (...) suffering and others in heaven who are not suffering. More precisely, it defends the following argument:1. No one who loves another can be perfectly happy or free from suffering if they know that their beloved is suffering.2. Anyone in hell suffers.3. Anyone in heaven is perfectly happy or at least free from suffering.4. There can be no one in heaven who is aware of the fact that his or her beloved is in hell.

Most philosophers, including all materialists I know of, believe that I am a complex thing?a thing with parts?and that my mental life is (or is a result of) the interaction of these parts. These philosophers often believe that I am a body or a brain, and my mental life is (or is a product of) brain activity. In this paper, I develop and defend a novel argument against this view. The argument turns on certainty, that highest epistemic status that a (...) precious few of our beliefs enjoy. For example, on the basis of introspection, I am certain that I am not in fierce pain right now. But if I am a complex thing like a body or a brain, then introspection might be a causal series of events extended in time. And any such process could go awry. So, if introspection is such a process, then I could gain good evidence that the introspective process has gone awry and that I am, contrary to appearances, feeling fierce pain right now. Therefore, the view that I am a complex thing like a body or a brain forces open the possibility that I cannot be certain that I am not feeling fierce pain right now. Since that is clearly not an open possibility, it follows that I am not a complex thing. I conclude by responding to three objections. (shrink)
