There are also letters in A Collection of Letters Illustrative of the Progress of Science, ed. J. Halliwell (London, 1840. Scholars in recent years have complained, usually justifiably, about the cost of the books they need for their research. While $78.00 per volume is a lot of money, it would be well spent by anyone with a serious interest in the person or the philosophy of Thomas Hobbes. These volumes, judiciously building upon the great labors of previous scholars, are the single most important contribution to Hobbes scholarship in the twentieth century. A. P. MARTINICH University of Texas at Austin Jeff Jordan, editor. Gambling on God: Essays on Pascars Wager. Lanham, MD: Rowman and Littlefield, 1994. Pp. viii + 164. Cloth, $49.oo. Paper, $19.95. Jeff Jordan has put together nine essays which give those who want to gamble on God something to think about. Though only three of them are really about Pascalk wager, all of them are worth reading. The most entertaining paper is Roy A. Sorensen's "Infinite Decision Theory." Sorensen confronts the St. Petersburg Paradox, which stems from the fact that there are available wagers with a potentially infinite payoff on which no one would bet $ao. Suppose you are offered $2n for each throw of a standard balanced coin until a head turns up. N = the number of tosses. It could be a long time--forever--before heads turns up. By the time n = loo you would have a bag of gold bigger than the sun. But Sorensen says the right bet is at least $23,but not much more. It is also true that since we don't know which actions God will reward, any human action has a possible infinite payoff and since all such actions have the same potential payoff none is better than the others. (Some god was moved to save Coleridge's Ancient Mariner, who had kindly thoughts about water-snakes.) Sorensen also notes that it is often said (Pascal would have agreed) that persons can be of infinite worth. If so, is rescuing one drowning person as good as rescuing five? The total worth seems to be the same. (Luckily, if Cantor is to be believed, there are larger and smaller infinities.) Sorensen ends inconclusively, but he is right that decision theory needs to address the infinite. Pascal would have had something to say. He thought that his bet was morally good. To bet on God is to act as if God exists. One who treats everyone as saved behaves as if God exists. (You don't know who is saved, but if you treat the saved as damned God will be annoyed whereas if you treat the damned as saved you won't detract from their ultimate penalty.) You don't have to bet $3, you only have to do what you ought to do anyway. The incremental cost of the bet appears to be zero. Anyhow, Pascal thought that it was not the infinite payoff (in the sense of a life of bliss) which provided the main motive for the bet but the fact that the required action was one's moral duty. Moreover, nook REVIEWS 689 if everyone behaves as if everyone is saved the result is a world in which God could appear and not be crucified. To be sure, there is a chance of an infinite life. Pascal believed human beings are potentially infinite--as is shown by our capacity for extending our knowledge to the infinite--but we are also potentially nothing, as is shown by the fact that the person never really appears in our scientific accounts. It is through God that our infinity is to be achieved, and so betting on God is also betting on ourselves in a perfectly intelligible way. This involw~s a notion of infinity not explored in any of these essays, which makes it possible to share with God without changing the divine nature...
