a sense while actually willing disbelief. Nonresistant nonbelief, lack of evidence, and sin When asked what he would say when facing God on judgment day, Bertrand Russell famously replied that he would say "Not enough evidence, God! Not enough evidence!" Some nonbelievers may have hidden from themselves what seems to them to be possible evidence of the divine, but the view of the hiddenness argument is that others have tried hard to believe in God. Schellenberg addresses this difference with his distinction between culpable and inculpable nonbelief, with the latter defined as "non-belief that exists through no fault of the non-believer." Historically, the Calvinist tradition has placed the blame on nonbelievers. Calvin's religious epistemology is based on the sensus divinitatis (Sense of Divinity), the view that the presence of God is universally perceived by all humans. Paul Helm explains, "Calvin’s use of the term 'sense' signals that the knowledge of God is a common human endowment; mankind is created not only as capable of knowing God, but as actually knowing him." According to this tradition, there is no inculpable or nonresistant nonbelief. Jonathan Edwards, the 18th century American theologian, claimed that while every human being has been granted the capacity to know God, successful use of these capacities requires an attitude of "true benevolence", a willingness to be open to the truth about God. Thus, the failure of non-believers to see "divine things" is in his view due to "a dreadful stupidity of mind, occasioning a sottish insensibility of their truth and importance." Demographics of theism and the problem of natural nonbelief In modern times, there are fewer proponents of these views. One reason is that, as Stephen Maitzen argues, anthropology has long established that while religious belief in general is essentially universal, belief in what Calvin would recognize as God is very unevenly distributed among cultures (consider for example God in Buddhism, Jain cosmology, or non-theistic animism). If God exists, then why, Maitzen asks, does the prevalence of belief in God vary so dramatically with cultural and national boundaries? Jason Marsh has extended this kind of demographic challenge by focusing on human evolution and cognitive science of religion. Why is theistic belief apparently non-existent among early humans but common at later times, at least in some regions? According to Marsh, the hiddenness problem is harder to answer once we appreciate that much nonbelief is 'natural', owing to the kinds
