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)

This new translation of the first Critique forms part of a fifteen-volume English-language edition of the works of Immanuel Kant under the general editorship of this volume’s editor-translators, Paul Guyer and Allen Wood. The edition, which is almost complete by now, comprises all of Kant’s published works along with extensive selections from his literary remains, his correspondence, and student transcripts of his lecture courses in metaphysics, ethics, logic, and anthropology. The Cambridge edition aims at a consistent English rendition of Kant’s (...) works, both within a given volume and across volumes. In terms of scope and detail, the Cambridge edition is unrivaled in any language, except for the authoritative Academy edition begun under the directorship of Wilhelm Dilthey in 1900, which, however, is still not completed and several volumes of which are in serious need of re-editing. In one case, that of the Opus postumum, the best edition currently available seems to be the one in the Cambridge edition. (shrink)

Astronomers of the first half of the nineteenth century viewed our solar system entirely differently from the way twentieth-century astronomers viewed it. In the earlier period the dominant image was of a set of planets and moons, both of which kinds of bodies were inhabited by intelligent beings comparable to humans. By the early twentieth century, science had driven these beings from every planet in our system except the Earth, leaving our solar system as more or less desolate regions for (...) the most part bereft of intelligent life. This essay traces this extinction and its relation to religious thought, noting the role played in it by Sir John Herschel and especially by William Whewell. The inverse square laws for gravitation, heat radiation, and light receive special attention, as does the question of the relevance of the Christian notions of a divine incarnation and redemption.

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.

From antiquity to the present, humans have debated whether intelligent life exists elsewhere in the universe. This presentation will survey this debate, examining the roles played in it by science, religion, philosophy, and other areas of human learning. One thesis that will be developed is that whether or not extraterrestrials exist, ideas about them have strongly influenced Western thought.

The discovery of exoplanets is a small part of the array of scientific arguments for and against the existence of extraterrestrial intelligence. Yet the recent stunning achievement of this program of observational astronomy has had a significant effect on scientific opinion and public interest. It also raises some key theological questions. New observing techniques are leading to the discovery of extrasolar planets daily. Earth-like planets outside of our Solar System can now be identified and in future years explored for signs (...) of life. This article maps the history of these discoveries and highlights some of the theological issues which are important to bring into dialogue with these scientific insights. (shrink)

Astrochristology, as a subfield within the more comprehensive astrotheology, speculates on the implications of what astrobiology and related space sciences learn about our future space neighbors. Confirmation of the existence of extraterrestrial intelligent civilizations living on exoplanets will force Christian theologians to decide on two issues. The first issue deals with the question: should Christians expect many incarnations, one for each inhabited exoplanet; or will the single incarnation in terrestrial history suffice? The second issue deals with the question: why is (...) there an incarnation in the first place? Does the divine presence in the historical Jesus mark a divine attempt to fix a broken creation or does it mark a divine self-communication that would occur with or without creation's fall into sin and death? Sorting these issues out is one task for astrochristology. My own position is to affirm both a single incarnation on Earth valid for cosmic redemption from the brokenness of creation in its present state. (shrink)

The possible existence of extraterrestrial life led in the eighteenth century to a heated debate on the unique status of the human being and of Christianity. One of those who discussed the new scientific worldview and its implications for theology was the Swedish natural philosopher and theologian Emanuel Swedenborg. This article discusses Swedenborg's astrotheological transformation, his use of theological arguments in his early cosmology, and his cosmogony that later on ended up in his use of contemporary natural philosophy in his (...) theology, especially concerning the question of the plurality of worlds. I will first sketch the astrotheology found in his natural philosophical works, and then turn to the astrotheology of his later spiritual teachings. In Swedenborg's works we find teleological arguments and a stress on the universality of the divine creation and Christianity, as well as anthropomorphic descriptions of extraterrestrial life. By reconciling contemporary astronomical ideas, among others the concept of the plurality of worlds, with Christian dogmas, Swedenborg refuted deistic conclusions that Jesus was merely a mortal, while at the same time keeping his belief in the modern astronomical worldview.
