I also described how each side can appeal to Ockham&#8217;s Razor (don&#8217;t complicate explanatory hypotheses more than necessary) as a tie-breaker. The problem with such appeals, I said, is that Ockham&#8217;s Razor can be wielded in different ways to different effect, leaving the outcome in this case somewhat ambiguous.<\/p>\n<p>Kurt raised the issue of intelligibility &#8211; do we really have enough of a grip on the idea of God, or of a transcendent Designer, for it to be a meaningful hypothesis? That&#8217;s a legitimate worry, one that a theist can only meet by articulating the idea of God in terms that we do have some grip on. Presumably we do have some understanding of notions like <span style=\"font-style: italic;\">having power<\/span>, <span style=\"font-style: italic;\">being a person<\/span>, <span style=\"font-style: italic;\">goodness<\/span>, <span style=\"font-style: italic;\">being knowledgeable and wise<\/span>, etc. for the theist to get started. Can the theist go far enough with this to meet the concern? I&#8217;ll leave that for you to decide or work out on your own.<\/p>\n<p>I&#8217;d like to close with a worry that I have about the Many Universes Hypothesis (MUH). The concern is that this amounts to an illegitimate multiplication of our probabilistic resources. Why illegitimate? Because it&#8217;s <span style=\"font-style: italic;\">ad hoc<\/span>. I don&#8217;t see that we have any <span style=\"font-style: italic;\">independent<\/span> reasons, apart from the desire to avoid positing a cosmic Designer, for thinking that these universes exist. By hypothesis, these universes are causally isolated from our own, so there couldn&#8217;t in principle be any empirical evidence for their existence. The most we can say is that, for all we know, they <span style=\"font-style: italic;\">could<\/span> exist. But I can say that much about pretty much anything, and that&#8217;s why I think there&#8217;s got to be independent justification of some kind for taking it seriously in this case. For example, if I come across a collected edition of Shakespeare&#8217;s writings I would explain it in terms of design. Alternatively, however, I <span style=\"font-style: italic;\">could<\/span> hypothesize it as the result of a <span style=\"font-style: italic;\">whole lot<\/span> of monkeys banging on word processors for a <span style=\"font-style: italic;\">very long<\/span> time. Now, if I had some independent reason for thinking that there actually were so many monkeys with access to functional word processors over such a long time, I might take that hypothesis seriously. But I have no such reasons, so I dismiss it out of hand.<\/p>\n<p>The questions I&#8217;d like to pose, then, are these: Are there any <span style=\"font-style: italic;\">independent<\/span> reasons for thinking that MUH is true? And if not, then why is MUH worth taking seriously whereas the monkey hypothesis is not?<a href=\"javascript:void(0)\" tabindex=\"10\"><span><\/span><\/a><\/p>\n<p>Finally, I would like to observe that the <span style=\"font-style: italic;\">adhocness <\/span>charge doesn&#8217;t count equally against theism because we have (or so it seems) several <span>independent <\/span>reasons for thinking that a being like God exists (cosmological arguments, religious experience, etc.).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In class today I described the cosmic fine-tuning version of the design argument and the standard &#8220;many universes&#8221; counter-hypothesis.
