A Brief History of Hell
Before we begin our examination of the arguments given against hell, it will be helpful to trace the development of eschatological thinking, from the earliest recorded speculations about the next world to contemporary attitudes. In this historical prelude we will chronicle the interplay of the various motifs--justice, love, punishment, and reformation--which characterize the modern debate. We will discover that both belief in and denial of hell have ancient pedigrees, and that the philosophical motivations for contemporary positions find their genesis in arguments of centuries past.
Providence, Freedom, and Human Destiny
According to some theists, God will never completely destroy moral evil or banish it from his creation entirely; instead, he will eventually confine moral evil to a specific region of his creation, a region known as hell, and those condemned to hell, having no hope of escape from it, will live out eternity in a state of estrangement from God as well as from each other. Let us call that the traditional doctrine of hell. Elsewhere I have argued that any form of theism which includes such a doctrine, even one that tries to preserve consistency by denying the universal love of God, is in fact logically inconsistent. But moderately conservative theists, as I have called them, have an argument for the traditional doctrine that some have found convincing, one that emphasizes libertarian free will. The argument is this. Because God is perfectly loving, he wills the good for every created person and wills the redemption of all who have fallen into evil; but because he has also given his loved ones the gift of freedom and some of them in fact exercise their freedom to reject him forever, it is simply not within his power, even as an omnipotent being, to redeem all of those who fall into evil. According to moderately conservative theists, therefore, the following hypothesis, which I shall call the Rejection Hypothesis (RH), is at least possibly true: (RH) Some persons will, despite God's best efforts to save them, freely and irrevocably reject God and thus separate themselves from God forever.
O2 constraints from Paleoproterozoic detrital pyrite and uraninite
Redox-sensitive detrital grains such as pyrite and uraninite in sedimentary successions provide one of the most conspicuous geological clues to a different composition of the Archean and early Paleoproterozoic atmosphere. Today, these minerals are rapidly chemically weathered within short transport distances. Prior to the rise of oxygen, low O2 concentrations allowed their survival in siliciclastic deposits with grain erosion tied only to physical transport processes. After the rise of oxygen, redox-sensitive detrital grains effectively vanish from the sedimentary record. To get a better understanding of the timing of this transition, we examined sandstones recorded in a scientifi c drill core from the South African 2.415 Ga Koegas Subgroup, a mixed siliciclastic and iron formation–bearing unit deposited on the western deltaic margin of the Kaapvaal craton in early Paleoproterozoic time. We observed detrital pyrite and uraninite grains throughout all investigated sandstone beds in the section, indicating the rise of oxygen is younger than 2.415 Ga. To better understand how observations of detrital pyrite and uraninite in sedimentary rocks can quantitatively constrain Earth surface redox conditions, we constructed a model of grain erosion from chemical weathering and physical abrasion to place an upper limit on ancient environmental O2 concentrations. Even conservative model calculations for deltaic depositional systems with suffi cient transport distances (approximately hundreds of kilometers) show that redox-sensitive detrital grains are remarkably sensitive to environmental O2 concentrations, and they constrain the Archean and early Paleoproterozoic atmosphere to have <3.2 × 10 –5 atm of molecular O2. These levels are lower than previously hypothesized for redox-sensitive detrital grains, but they are consistent with estimates made from other redox proxy data, including the anomalous fractionation of sulfur isotopes. The binary loss of detrital pyrite and uraninite from the sedimentary record coincident with the rise of oxygen indicates that atmospheric O2 concentrations rose substantially at this time and were never again suffi ciently low (<0.01 atm) to enable survival and preservation of these grains in short transport systems.
