A synopsis for "Bringing Life to the Stars" by David Duemler: One of the worst tragedies of the 20th century occured in Nazi Germany when millions of people were put to death in concentration camps. It is also tragic when a young child is run over by a truck. But if we are to state which of these two outcomes is worse, it is clear that the death of one child, as horrible as it may be, pales into insignificance when compared to the suffering and death of millions. Similarly, one would prefer the most joyous experiences of one's entire life to an experience which is merely pleansant. Simply put, amount matters. This simple insight has enormous consequences when we consider the possibility of bringing life to the stars, thereby increasing the amount of life countless times. "Bringing Life to the Stars" is an attempt to address the question, "Should we bring life to the rest of the solar system, or, if possible, to the rest of the galaxy?" Chapter 1: An Ethical Foundation The first chapter, which provides an ethical foundation for the rest of the book, begins by discussing three factors which may limit attempts to think about ethics; 1) amount matters, but there is a tendency for many people to overlook amounts, 2) our immediate intuition is faulty, especially when we are faced with questions for which our background has not prepared us well, 3) we are likely to be biased toward ourselves, our species, and our planet. Moving on to an examination of ethics itself, three criteria are provided which may help us to judge proposed ethical foundations: 1) In suggesting that X exists and/or has value are we taking huge inferential leaps beyond the available data? 2) Is it biologically plausible to suggest that X exists and/or has a biological function? 3) If X exists is it of inherent value? Any proposed foundation which does not pass all three criteria is not given further consideration. Proposed foundations for an ethical system include; pleasure and pain, life itself, natural rights, integrity, diversity, the soul, and intelligence. Each of these proposals is examined. Rights- based ethical systems fail all three criteria. The proposal of a soul fails criterion 1 as huge inferential leaps are required for such a system. All other proposed foundations, with the exception of pleasure and pain, fail to look at the underlying conditions which ultimately determine value and thus fail criterion 3. Pleasure and pain, broadly defined to include all types of suffering and fulillment, is a foundation which succeeds on all three criteria and thus serves as the basis for the rest of the book. A hedonistic, aggregate, act-utilitarian system is proposed and defended against common criticisms. This system is then used to derive the following two axioms (which are further explained and qualified in the book): 1) Life which exists in a fulfilling environment tends to be of positive value. 2) In such an environment two lives are on average of twice the value of one life. It is noted that if life were to spread throughout either the solar system or the galaxy the amount of life could increase countless times, and suggested that if these new worlds are fulfilling the amount of value would increase countless times. This would make all other problems and possibilities in our world, except in that they may affect the probability of achieving this vision, trivial in comparison. Chapter 2: Creating New Worlds The basic conditions for the creation of space habitats are examined; material resources, energy resources, meteoroids and cosmic rays, the possibility of isolation and/or confinement, the creation of ecosystems, and conditions for non-human animals. A conclusion is reached that worlds in free space, if they could be fulfilling, would be preferable to worlds on the surfaces of moons or planets, as moons and planets are relatively inefficient (e.g., there are thousands of miles of material beneath your feet not being directly used, whereas in a space habitat there need only be a couple meters). Independent estimates that our solar system could hold billions of times as much life as Earth are presented. In addition to the presence of abundant material resources in space it is shown that the Sun as a source of energy can be used much more readily when it is not blocked out by Earth's atmosphere or shadow (i.e., night). A second conclusion is that a tremendous diversity of life would be possible in these worlds. There could be countless such worlds in a variety of shapes and sizes and containing a variety of ecosystems. Each world would contain a few tens or hundreds of square miles of land area. Travel to nearby worlds would be accomplished in minutes or hours with no concern about potholes or a necessity toplow through an atmosphere and with virtually no use of energy whatever. Drawing upon work in environmental psychology, human environmental preferences are examined with an emphasis on application to design of worlds in space. Examples of possible worlds are briefly described. The limits of present and some conceivable near term launch vehicles and "intelligent" machines are briefly examined. Finally it is noted that as machine intelligence advances in worlds without immediate material concerns a "point of freedom" would be approached. At such a point machines would perform whatever work our descendants do not wish to and thereby would make available material goods without requiring serious human effort. As such a point is approached life would change considerably and the direction of such change can best be predicted when one takes into account the limits of consciousness and the limits of society (i.e., the following two chapters). Chapter 3: Limits of Consciousness The extent to which new worlds would be fulfilling may be limited by the human capacity for rationality. Information about cognition in non-human animals is presented to provide a foundation for understanding human cognition. Moving to humans, it is suggested that we could closely approach ideal decisions if we had unlimited access to information, if we were in concious control of our decisions, and if we had a special capacity for logic. It is argued however that we fall short of these ideals in a number of ways: 1) Consciousness is multifaceted, with different parts of the brain being involved in different aspects of conscious awareness. There is no single center in the brain which is in control of our behavior. 2) Consciousness plays a circumscribed role in cognition. Conscious attention is used primarily early in the learning process, before things become automatized, and in general when we are facing unusual situations. Much of our decision making relies on unconsicous processes. 3) We have not evolved a special capacity for logic. An a priori argument involving natural selection is presented and examples of human difficulties with reasoning are presented. 4) We have not evolved a special capacity for ethical thought. It is argued that in the future in space we can reduce the damage caused by these limitations: 1) To some extent knowledge is cumulative and thre are reasons to suspect that the extent of human knowledge will increase tremendously in the coming centuries. 2) We are capable of learning about our limitations, and will be more so in the future given the cumulative nature of knowledge. With such understanding we are capable of behaving in ways that account for these limitations. Moreover, as we approach the "point of freedom," motivations underlying many rationalizations or "motivated errors," may be reduced or eliminated. 3) As life moves beyond the possibility of nuclear destruction and continues to become more advanced almost any errors which are made eventually be corrected. This will not apply as clearly to minor day to day errors, but reducing the number and cost of major errors can make a huge difference in how fulfilling the worlds are. Chapter 4: The Limits of Society "Immdiate return societies" are basically a subgroup of hunters and gatherers including the !Kung, the Mbuti, the Hadza and others who live (lived) without anything approaching formal legal or economic systems. Thus some aspects of their lifestyle may be similar to what we would expect in space habitats once the point of freedom is approached. These societies share a number of characteristics including a profound egalitarianism, relatively free access to resources and freedom to move, a short work week, secure identity, a stress on cooperation rather than competition, and physical closeness. A brief look at the history of Western Civilization indicates that modern industrial societies provide a stark contrast with respect to each of these characteristics. We wold thus expect tremendous change on the societal scale as humans move beyond Earth. Modern industrial societies also have advantages due to relatively advanced technology. our descendants in space would have even more advanced technology and thus a greater variety of options. It is argued that when life in space approaches the point of freedom it will indeed share the noted characteristics of immediate return societies, with the possible exceptions of secure identity and physical closeness. Though our descendants would be able to choose secure identity and physical closeness, may choose otherwise due to a greater availability of options. The social worlds which develop in space would in some respects differ from anything found in our history on Earth due to the relatively advanced state of knowledge and capacity for rationality. Other issues relevant to present and future social systems including aggression and reconciliation, altruism and reciporcity, and behavioral genetics, are discussed. Chapter 5: A Cosmic Perspective It is shown that a cosmic perspective, a concern about the universe as a whole, has been found among those with environmental concerns since nineteenth century, including Emerson, Thoreau, and Muir. It is suggested that it would be inconsistent to be concerned about the maintenance of some ecosystems and not about the creation of others. The following common questions and criticisms are addressed: 1) "How could artificial worlds in free space compare with Yosemite?," 2) "Maybe it would be nice for some people but I wouldn't like it.," 3) "Aren't people who dream of bringing life to the stars simply being irresponsible?," 4) "Why should someone believe that another 'technological fix' will solve our problems?," 5) "Why should people give up on Earth? Shouldn't we solve the problems of Earth first?," 6) "Why don't we at least wait until it can be done more efficiently? Or until the push can be better directed?" It is suggested that some of these comments and criticisms are of great value in that they may help to better direct our efforts. However, some are self-centered, assuming that our present day problems, our planet, and near term considerations in general are what is of most importance. Chapter 6: The Limits of the Possible When we move to the longest term considerations we are concerning ourselves with the limits of the possible. A brief look is taken at: possible worlds, possible life forms, the possibility of traveling to other stars, the possibility of alien civilizations within the Milky Way, the possibility that the universe will end, and finally the possibility that the universe is a cyclical phenomenon. -- INTERNET: jim@netlink.cts.com (Jim Bowery) UUCP: ...!ryptyde!netlink!jim NetLink Online Communications * Public Access in San Diego, CA (619) 453-1115
