 Devious ETs: Suppose you are abducted by very powerful and advanced extraterrestrials, who demonstrate their intent and power to destroy the Earth. Moreover, these fiendish ETs offer but one chance of salvation for humankind – you acquire and maintain a belief for which you lack adequate evidence. You adroitly point out that you cannot just will such a belief, especially since you know of no good reason to think it true. Devilish in their anticipation and in their technology, the ETs produce a device that can directly produce the requisite belief in willing subjects, a serum, say, or a supply of one-a-day doxastic-producing pills. It is clear that you would do no wrong by swallowing a pill or injecting the serum, and, hence, bringing about and maintaining belief in a proposition for which you lack adequate evidence, done to save humankind. Indeed, it is clear that you are in fact obligated to bring about the requisite belief, even though you lack adequate evidence for it.
