Due to the logical relations between theism and intelligent design (id), there are two challenges to theism that also apply to id. In the falsifiability challenge, it is charged that theism is compatible with every observation statement and thus asserts nothing. I argue that the contentious assumptions of this challenge can be avoided without loss of precision by charging theism (and thus id) directly with the lack of observational assertions. In the translatability challenge, it is charged that theism can be (...) translated into a (non-theistic) set of observation statements without loss of cognitive content. I argue that the contentious assumptions of this challenge are avoided by the related charge that the (non-theistic) evolutionary theory makes all the observational assertions of id, while the converse does not hold. Elliott Sober has argued that id meets the falsifiability challenge, but, since it makes almost no observational assertions, is not testable. I point out two problems with Sober’s argument and show that id is both deductively and probabilistically testable. Sober’s argument, I suggest, inconsistently combines the modified falsifiability challenge with the modified translatability challenge. If his claims about id’s observational assertions are true, however, id succumbs to the modified translatability challenge. (shrink)

Hume's thoroughgoing religious scepticism is set within the context of the Scottish Enlightenment. Against some interpreters, it is argued that, although elusive, his ‘attenuated deism’ (Gaskin) is not wholly dismissive of all forms of religious thought and practice. His position is further compared with contemporary expressions of ‘new atheism’. Despite some obvious similarities, Hume's position is judged more nuanced both in terms of content and rhetorical strategy.

My aim in this paper is to critically assess two opposing theses about the epistemology of religious belief. The first one, developed by John Mackie, claims that belief in God can be justified or warranted only if there is a good argument for the existence of God. The second thesis, elaborated by Alvin Plantinga, holds that even if there is no such argument, belief in God can be justified or warranted. I contend that the first thesis is plausibly false, because (...) belief in God is not just like a scientific hypothesis, and the second thesis is likely true if epistemic externalism is the correct view. However, even if the second thesis is true, I argue that to work on good arguments for God’s existence is unavoidable in order to cope with a new version of the Great Pumpkin objection, as well as to achieve other relevant purposes such as to convince rational observers outside the theistic community that belief in God is likely justified or warranted.

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.
