Speaker: Daniel Nolan (UC, Santa Cruz)
The ‘Olamā-ye Eslām is a Zoroastrian apologetic work, perhaps from the thirteenth century CE. This paper argues that it contains a distinctive response to the problem of why an omnipotent and all-good deity would permit the existence of evil. Ormazd, the great good deity of Zoroastrianism, will not directly destroy or disable Ahriman, the chief source of all evil, because that would be incompatible with Ormazd’s perfect goodness. Instead, Ormazd is only permitted to achieve the neutralization of Ahriman through indirect means, wearing the author of evil out in a struggle for the material world. In focusing on which actions the good deity may perform, as opposed to the ends the good deity seeks, this theodicy takes an approach not found in contemporary discussions of the problem of evil.
