Putting people into places and situations unprecedented in history is stirred the imagination while the human experience was expanding and redefining. Yet, space exploration compels humans to confront a hostile environment of cosmic radiations, radical changes in the gravity and magnetic fields, as well as social isolation. Therefore, any space traveller is submitted to relevant health-related threats. In the twenty-first century, human space flight is poised to continue, but it will enjoy the ongoing developments in science and technology. It will become more networked, more global, and more oriented toward primary goals. A novel international human space flight policy could help achieve these objectives by clarifying the rationale, the ethics of acceptable risk, the role of remote presence, and the need for balance between funding and ambition to justify the risk of human lives. In order to address such a challenge, a preliminary careful survey of the available scientific data is mandatory to set forth adequate countermeasures. Envisaged solutions should provide a sound and technically feasible approach for counteracting microgravity and cosmic rays effects, which represent the main health risk for space crews. This objective must necessarily be sustained by national/international space agencies, which would coordinate their common efforts into a defined international spaceflight program.

    Some system of authority is a requirement of all communal living, and it is only the man dwelling in isolation who is not forced to respond, through defiance or submission, to the commands of others. Obedience, as a determinant of behavior is of particular relevance to our time. It has been reliably established that from 1933 to 1945 millions of innocent people were systematically slaughtered on command. Gas chambers were built, death camps were guarded, daily quotas of corpses were produced with the same efficiency as the manufacture of appliances. These inhumane policies may have originated in the mind of a single person, but they could only have been carried out on a massive scale if a very large number of people obeyed orders.Obedience is the psychological mechanism that links individual action to political purpose. It is the dispositional cement that binds men to systems of authority. Facts of recent history and observation in daily life suggest that for many people obedience may be a deeply ingrained behavior tendency, indeed, a prepotent impulse overriding training in ethics, sympathy, and moral conduct. C. P. Snow (1961) points to its importance when he writes:When you think of the long and gloomy history of man, you will find more hideous crimes have been committed in the name of obedience than have ever been committed in the name of rebellion. If you doubt that, read William Sbirer's 'Rise and Fall of the Third Reich.' The German Officer Corps were brought up in the most rigorous code of obedience . . . in the name of obedience they were party to, andassisted in, the most wicked large scale actions in the history of the world. (p. 24)The Nazi extermination of European Jews is the most extremeinstance of abhorrent immoral acts carried out by thousands ofpeople in the name of obedience. Yet in lesser degree this type ofthing is constantly recurring: ordinary citizens are ordered todestroy other people, and they do so because they consider ittheir duty to obey orders. Thus, obedience to authority, longpraised as a virtue, takes on a new aspect when it serves amalevolent cause; far from appearing as a virtue, it is transformedinto a heinous sin. Or is it?The moral question of whether one should obey when commands conflict with conscience was argued by Plato, dramatized in "Antigone," and treated to philosophic analysis in every historical epoch Conservative philosophers argue that the very fabric of society is threatened by disobedience, and even when the act prescribed by an authority is an evil one, it is better to carry out the act than to wrench at the structure of authority. Hobbes stated further that an act so executed is in no sense the responsibility of the person who carries it out but only of the authority that orders it. But humanists argue for the primacy of individual conscience in such matters, insisting that the moral judgments of the individual must override authority when the two are in conflict.The legal and philosophic aspects of obedience are of enormous import, but an empirically grounded scientist eventually comes to the point where he wishes to move from abstract discourse to the careful observation of concrete instances. In order to take a close look at the act of obeying, I set up a simple experimentat Yale University. Eventually, the experiment was to involve more than a thousand participants and would be repeated at several universities, but at the beginning, the conception was simple. A person comes to a psychological laboratory and is told to carry out a series of acts that come increasingly into conflict with conscience. The main question is how far the participant will comply with the experimenter's instructions before refusing to carry out the actions required of him.But the reader needs to know a little more detail about the experiment. Two people come to a psychology laboratory to take part in a study of memory and learning. One of them is designated as a "teacher" and the other a "learner." The experimenter explains that the study is concerned with the effects of punishment on learning. The learner is conducted into a room, seated in a chair, his arms strapped to prevent excessive movement, and an electrode attached to his wrist. He is told that he is to learn a list of word pairs; whenever he makes an error, be will receive electric shocks of increasing intensity.The real focus of the experiment is the teacher. After watching the learner being strapped into place, he is taken into the main experimental room and seated before an impressive shock generator. Its main feature is a horizontal line of thirty switches, ranging from 15 volts to 450 volts, in 15-volt increments. There are also verbal designations which range from Slight SHOCK to Danger--Severe SHOCK. The teacher is told that he is to administer the learning test to the man in the other room. When the learner responds correctly, the teacher moves on to the next item; when the other man gives an incorrectanswer, the teacher is to give him an electric shock. He is to start at the lowest shock level ( 15 volts) and to increase the level each time the man makes an error, going through 30 volts, 45 volts, and so on.The "teacher" is a genuinely naive subject who has come to the laboratory to participate in an experiment. The learner, or victim, is an actor who actually receives no shock at all. The point of the experiment is to see how far a person will proceed in a concrete and measurable situation in which he is ordered to inflict increasing pain on a protesting victim.

    - help is finally at hand. That help comes in the comfortingly accessible form of Stephen Trombley's Short History of Western Thought, which outlines the 2,500-year history of European ideas from the philosophers of Classical Antiquity to the thinkers of today, No major representative of any significant strand of Western thought escapes Trombley's attention: the Christian Scholastic theologians of the Middle Ages, the great philosophers of the Enlightenment, the German idealists from Kant to Hegel; the utilitarians Bentham and Mill; the transcendentalists Emerson and Thoreau; Kierkegaard and the existentialists; the analytic philosophers Russell, Moore, Whitehead and Wittgenstein; and - last but not least - the four shapers-in-chief of our modern world: the philosopher, historian and political theorist Karl Marx; the naturalist Charles Darwin, proposer of the theory of evolution; Sigmund Freud, the father of psychoanalysis; and the theoretical physicist Albert Einstein, begetter of the special and general theories of relativity and founder of post-Newtonian physics.

    This world-famous bestseller has withstood the test of time, inspiring countless books and films, including the author's own popular sequel, The Eyes of the Sphinx. But here is where it all began--von Daniken's startling theories of our earliest encounters with alien worlds, based upon his lifelong studies of ancient ruins, lost cities, potential spaceports, and a myriad of hard scientific facts that point to extraterrestrial intervention in human history. Most incredible of all, however, is von Daniken's theory that we ourselves are the descendants of these galactic pioneers--and the archeological discoveries that prove it... * An alien astronaut preserved in a pyramid * Thousand-year-old spaceflight navigation charts * Computer astronomy from Incan and Egyptian ruins * A map of the land beneath the ice cap of Antarctica * A giant spaceport discovered in the Andes Includes remarkable photos that document mankind's first contact with aliens at the dawn of civilization.

    Written in clear and incisive prose, The Wealth of Nations articulates the concepts indispensable to an understanding of contemporary society; and Robert Reich's Introduction both clarifies Smith's analyses and illuminates his overall relevance to the world in which we live. As Reich writes, "Smith's mind ranged over issues as fresh and topical today as they were in the late eighteenth century--jobs, wages, politics, government, trade, education, business, and ethics."Introduction by Robert Reich - Commentary by R.

    [captures] the relentless urgency of Lucretius' didacticism, his passionate conviction and proselytizing fervour.' --The Classical Review

    This predicament seems inevitable, but in fact it's quite new. In medieval Europe, God's calling was a grounding force. In ancient Greece, a whole pantheon of shining gods stood ready to draw an appropriate action out of you. Like an athlete in “the zone,” you were called to a harmonious attunement with the world, so absorbed in it that you couldn’t make a “wrong” choice. If our culture no longer takes for granted a belief in God, can we nevertheless get in touch with the Homeric moods of wonder and gratitude, and be guided by the meanings they reveal?All Things Shining says we can. Hubert Dreyfus and Sean Dorrance Kelly illuminate some of the greatest works of the West to reveal how we have lost our passionate engagement with and responsiveness to the world. Their journey takes us from the wonder and openness of Homer’s polytheism to the monotheism of Dante; from the autonomy of Kant to the multiple worlds of Melville; and, finally, to the spiritual difficulties evoked by modern authors such as David Foster Wallace and Elizabeth Gilbert.Dreyfus, a philosopher at the University of California, Berkeley, for forty years, is an original thinker who finds in the classic texts of our culture a new relevance for people’s everyday lives. His lively, thought-provoking lectures have earned him a podcast audience that often reaches the iTunesU Top 40. Kelly, chair of the philosophy department at Harvard University, is an eloquent new voice whose sensitivity to the sadness of the culture— and to what remains of the wonder and gratitude that could chase it away—captures a generation adrift.Re-envisioning modern spiritual life through their examination of literature, philosophy, and religious testimony, Dreyfus and Kelly unearth ancient sources of meaning, and teach us how to rediscover the sacred, shining things that surround us every day. This book will change the way we understand our culture, our history, our sacred practices, and ourselves. It offers a new—and very old—way to celebrate and be grateful for our existence in the modern world.
