This paper approaches the question of terraforming—the changing of extraterrestrial environments to be capable of harboring earth-based life—by arguing for a novel conception of moral status that accounts for extraterrestrial bodies like Mars. The paper begins by addressing pro-terraforming arguments offered by James S. J. Schwartz before offering the novel account of moral status. The account offered builds on and modifies Keekok Lee’s No External Teleology Thesis (NETT), while defending a proposed Non-Fungibility Thesis (NFT). The NETT is modified and defended (...) with specific reference to Lee’s work on artifactuality and transgenic organisms. The NFT builds on work around objectification and irreplaceability, offering an account that recognizes the importance of bearers of value above and beyond the mere value they purportedly possess. Finally, the plausibility of the account is established by an overview of its applicability to other possible candidates for moral status. (shrink)

Public theology is conceived in the church, reflected on critically in the academy and addressed to the world for the sake of the world. The development of a theology of nature is included in the public theologian’s list of tasks of nature that is scripturally based and heavily informed by the natural sciences. Astrotheology is one product. Astrotheology engages astrobiology and other space sciences, firstly, by critically exposing the extraterrestrial intelligence myth at the heart of science and secondly, by partnering (...) in thinking through public policy proposals with astroethicists.Contribution: The HTS collection on ‘Theology and Nature’ sparks theological discussion both within and beyond the church. By developing the fields of astrotheology and astroethics, this article contributes to a ‘Theology of Nature’ as an exercise in Public Theology. (shrink)

As we envision constructive undertakings in the field of religion and science for the next decade, the emerging agenda of astrotheology is opening up a new theater for enquiry. Astrotheology provides a critical theological response to the field of astrobiology while critically assessing exciting new research on life in our solar system and the discovery of exoplanets. This article proposes four tasks for the astrotheologian: deliberate on (1) the scope of creation: is God's creation Earth-centric or does it include the (...) entire cosmos? (2) the question whether a single divine incarnation on Earth suffices for the cosmos or whether multiple incarnations—one for each inhabited planet—is required; (3) whether astrobiologists and other space scientists are sticking to their science or smuggling in ideology; and (4) readying terrestrial life for contact with extraterrestrial life by enumerating issues to be taken up by astroethics.

The field of Astroethics addresses moral and societal issues arising out of speculation regarding terrestrial contact with extraterrestrial life in both its intelligent and non-intelligent forms. This chapter tackles 15 ethical quandaries, 12 of which are associated with space exploration within the solar system plus 3 with exoplanet communication. Within our solar ghetto, scientists expect at best to find only microbial life, leaving intelligent life to exoplanets elsewhere in our galaxy. The intra-solar system quandaries are these: What does planetary (...) protection mean? Does microbial life have intrinsic value? Should space explorers invoke the Precautionary Principle? Should we clean up our space junk? What should we do about satellite surveillance? Should we weaponize space? Should scientific research take priority over commercial space ventures? Should we terraform Mars? Should we colonize Mars? Should we prepare for bombardment of Earth by asteroids? Should we rely upon a single planetary community of moral deliberation? Should we pursue the good of the galactic commons? The extra-solar quandaries deal with three degrees of extraterrestrial intelligent creatures: those with less intelligence than us Homo sapiens, our Extraterrestrial Intelligent creatures peers in intelligence, and ETI who are superior to us in intelligence. To each quandary we ask: What is our terrestrial moral responsibility toward extraterrestrial life? Our answer is grounded in an appeal to a galactic common good. (shrink)

We are probably alone in the universe—a conclusion based on observations of over 4,000 exoplanets and fundamental physical constraints. This article updates earlier arguments with the latest astrophysical results. Since the discovery of exoplanets, theologians have asked with renewed urgency what the presence of extraterrestrial intelligence says about salvation and human purpose, but this is the wrong question. The more urgent question is what their absence says. The “Misanthropic Principle” is the observation that, in a universe fine-tuned for life, the (...) circumstances necessary for intelligence are rare. Rabbis for 2,000 years discussed the existence of ETI using scriptural passages. We examine the traditional Jewish approaches to ETI, including insights on how ETI affects our perception of God, self, free-will, and responsibility. We explore the implications of our probable solitude, and offer a Jewish response to the ethical lessons to be drawn from the absence of ETI. (shrink)

In the future, human destiny may depend on our ethics. In particular, biotechnology and expansion in space can transform life, raising profound questions. Guidance may be found in Life-centered ethics, as biotic ethics that value the basic patterns of organic gene/protein life, and as panbiotic ethics that always seek to expand life. These life-centered principles can be based on scientific insights into the unique place of life in nature, and the biological unity of all life. Belonging to life then implies (...) a human purpose: to safeguard and propagate life. Expansion in space will advance this purpose but will also raise basic questions. Should we expand all life or only intelligent life? Should we aim to create populations of trillions? Should we seed other solar systems? How far can we change but still preserve the human species, and life itself? The future of all life may be in our hands, and it can depend on our guiding ethics whether life will fulfil its full potentials. Given such profound powers, life-centered ethics can best secure future generations. Our descendants may then understand nature more deeply, and seek to extend life indefinitely. In that future, our human existence can find a cosmic purpose. (shrink)
