The problem of evil has long perplexed traditional theists: Why do terrible events, such as crimes, wars, and natural disasters, occur in a world believed to be created by an omnipotent and wholly good God? In The Problem of Evil for Atheists, Yujin Nagasawa offers a fresh perspective that seeks to transform the perennial philosophical debate on this matter. The book contends that the problem of evil surpasses its conventional understanding, impacting not only traditional theists but also posing a challenge for atheists and other ‘non-theists’, including pantheists, axiarchists, and followers of Eastern religious traditions. Moreover, it posits that traditional theists, who typically embrace some form of supernaturalism, are better equipped to address the problem than naturalist atheists/non-theists because the only potentially successful response requires supernaturalism. Conversely, it suggests that if atheists/non-theists can develop a successful naturalist response, traditional theists can also adopt it. The volume concludes that traditional theists are better positioned than atheists/non-theists to grapple with the problem-an unexpected assertion, given that the problem of evil is normally viewed as an argument against traditional theism and in favour of atheism/non-theism. The Problem of Evil for Atheists presents a comprehensive defence of a fundamentally new approach to tackling the age-old philosophical conundrum. By challenging the conventional perspective, it endeavours to reshape our understanding and interpretation of evil in a profound manner.
