Extract

Can Pascal's wager for the existence of God be turned against the religious believer and used as an argument for not believing in God? Although such an argument has been very briefly sketched by others its details have remained undeveloped. In this paper this argument is worked out in detail in the context of decision theory and is defended against objections. The result is a plausible argument for atheism.

page 57 note 2 As many scholars have pointed out, Pascal was not so naive as to suppose that one could believe in God by an act of will. However, he did think that belief could be developed by acting in certain religious ways, for example by attending mass and taking the sacraments. So the two choices of the non-believer were really to act or not to act in religious ways.

page 59 note 1 Clearly then the view is mistaken that one must assume that the probability is 1/2 that God exists and 1/2 that he does not in order to make the argument work. For this mistaken criticism see Beardsley, Monroe and Beardsley, Elizabeth, Philosophical Thinking: An Introduction (New York: Harcourt, Brace and World, p. 140).Google ScholarHacking, (op. cit. p. 189)Google Scholar claims that Pascal is committed to this assumption in one formulation of his argument. However, this assumption is not made in the version of the argument considered here.

page 59 note 3 Whether there is an infinite number of possibilities, as Flew has maintained, is another question. In any case an infinite number of possibilities is not needed to refute the argument, although such an assumption is useful in providing reasons for non-belief.

page 61 note 1 The above argument will not work in exactly the same way against belief in Supernatural Beings with finite rewards and punishments. However, with slight modification the argument can proceed as before. Space does not permit me to show this extension here.

page 62 note 1 When worship is translated into actual religious practice, worship can be time consuming, expensive and troublesome. The long hours spent in religious rituals, the extreme penances required by some sects, the tithe required by some churches, and the asceticism required in others are some of the more obvious examples of the negative value of religious worship.

page 63 note 2 There seem to me to be three main lines of argument to show that the hypothesis that no Supernatural Beings exist is a better explanation of the available evidence that the hypothesis that some Supernatural Beings exist. First, other things being equal, hypotheses that postulate Supernatural Beings are Is simple than hypotheses that do not. Second, supernatural hypotheses tend to be less testable than naturalistic hypotheses. Third, from a historical point of view, hypotheses postulating supernatural entities have in realm after realm been replaced by hypotheses that don't; on inductive grounds one can expect this replacement to continue. Consequently the hypothesis that no Supernatural Beings exist is likely to be a better explanation of the available evidence than the hypothesis that some Supernatural Beings do exist; consequently the hypothesis that no Supernatural Beings exist is likely to be inductively better justified than its negation.
