-
- Welcome to the symposium on "Life Beyond Earth and the Mind of Man." Our
- topic will be the search for life in the universe and the ramifications of
- its possible discovery. Although there have been a handful of scientific
- meetings on this topic, to the best of my knowledge this it the first time
- there has ever been a meeting where a distinquished panel from diverse fields
- will discuss the topic in an open forum.
-
- A generation ago almost all scientists would have argued, often "ex
- cathedra," that there probably is no other life in the universe beside what
- we know here on Earth. But as Martin Rees, the cosmologist, has succinctly
- put it, "absence of evidence is not evidence of absence." Beyond that, in
- the last decade or so the evidence, albeit circumstantial, has become large
- indeed, so large, in fact, that today many scientists, probably the majority,
- are convinced that extraterrestrial life surely must exist and possibly in
- enormous abdundance. The question now is no longer so much of IF as of
- WHERE, and with regard to the search, it has also become WHEN, for ultimate
- contact seems to many serious thinkers to be virtually inevitable. A short
- passage from the recent report of the Astronomy Survey Committee of the
- august National Academy of Sciences of the United States, the Nation's most
- disnguished scientific body, gives an example of the modern scientific
- attitude:
-
- "Each passing year has seen our estimates of the probability of life
- in space increase, along with our capabilities for detecting it. More
- and more scientists feel that contact with other civilizations is no
- longer something beyond our dreams but a natural event in the history
- of mankind that will perhaps occur within the lifetime of many of us.
- The promise is now too great, either to turn away from it or to wait
- much longer before devoting major resources to a search for other
- intelligent beings... In the long run this may be one of science's most
- important and most profound contributions to mankind and to our
- civilizatioin."
-
- I believe it fair to say, therefore, that this momentous topic deserves
- careful, thorough discussion, and that is what I hope we shall give it today.

- ADDITIONAL MEMBERS OF THE PANEL
-
- ASHLEY MONTAGU: renowned anthropologist and social biologist For many years
- he was chariman of the Department of Anthropology at Rutgers He is the author
- of scores of books and research papers on a variety of topics in the social
- sciences, including the social and cultural development of mankind
-
- KRISTER STENDAHL: an outstanding churchman and theologican, who is the Dean
- of Harvard School of Divinity. Dr. Stendahl is considered to be one of the
- Nation's most scholarly theologians.
-

- WALD
-
- The chance of breaking out of the solar system and establishing physical
- contact - or the chance of any creature in outer space establishing physical
- contact with us, coming to us from some other solar system -- seems to me so
- remote as to be almost nil. In order to do that, one would have to travel at
- the speed of light and it is rather hard to travel at the speed of light and
- not be light. SO I rather doubt that physical contact is possible.
-
- But we now are discuuing another kind of contact, and that is communication.
- May I say, so that we can have a somewhat warmer and2 livelier conversation as
- this meeting goes on, that I can conceive of no nightmare as terrifying as
- establishing such communication with a so-called superior (or if you wish,
- advanced) technology in outer space. You see, I see no escape from the
- thought that more advanced technologies exist, very likely in a number of
- places within our own galaxy. That though in itself is a little terrifying to
- me, I muyst say, because of my view of and identification with the human
- enterprise.
-
- You see, when I ask myself as a lifelong sicentist, "What's science about?"
- the answer is not to increase the catalog of facts, it is to achieve
- understanding. It means a great deal that one of the greatest human
- enterprises is understnaind. It is something that men have sweated out, to
- the greater dignity and worth of man. The thought that we might attach, as by
- an umbilical cord, to some more advanced civilization, with its more advanced
- science and technology, in outer space does not thrill me, but just the
- opposite. You see, I think it might thrill and fill with elation the people
- who did it; but that is true of almost any enterprise one could name, however
- horrifying, however destructive to the rest of mankind. You cannot think of
- anything so horrifying that some person would not have a feeling of personal
- accomplishment at carrying it out; and I would say that the rest of us had
- better restrain him.
-
-
- MONTAGU
-
-
- These two facts render it likely, to judge from our immediate past
- performance [*note: 10,000 years of humanity as opposed to longer
- civilization maintenance by an extraterretestrial society], that upon
- encountering them, our Government will immediately convene a committee in
- order to determine whether these creatures consitute a threat to democracy.
- Since their physical appearance will be markedly different and since
- difference is usually equated in our culture with inferiority, no matter what
- the intellectual status of these creatures may be, and regardless of the
- healthy ways of life that characterize them, we shall, of course, know
- exactly where we belong in the nature of things.
-
- In short, we would have rather a problem on out hands, but we would not want,
- I suppose, the American way of life to be contaminated. With the record we
- have of treatment of the American Indians, the blacks, the Chicanos, and
- other minority groups, and our record in such places as Mexico, the
- Philippines, China, Vietname, and wherever else we have attempted to make the
- world safe for democracy, you can foresee what is likely to happen.
-
- I hope you will understand that the assignment I was given was worded in the
- form, "How might human beings react to the discovery of life beyond Earth?"
- and I have interpreted the word "might" to mean "how may we probably react"
- and "how should we react." We are coming to the "should."
-
- I do not think we should wait until the encounter occurs; we should do all in
- our power to prepare ourselves for it. The manner in which we first meet may
- determine the character of all our subsequent relations. Let us never forget
- the fatal impact we have had upon innumerable peoples on this Earth --
- peoples of our own species who trusted us, befriended us, and whom we
- destroyed by our thoughlessness and insensitivity to their needs and
- vulnerabilities.
-
- The simple truth is that before we can communicate with others succesfully,
- we must first learn to communicate with ourselves succesfully, and we are a
- long way from having achieved that. Perhaps that is where we ought to begin
- -- with ourselves. Learning to communicate with ourselves, with all the
- different peoples and nations of the Earth. We go on behaving as if we
- believe there is very little wrong, if anything, with ourselve. We refuse to
- face the fact that we have already virtually desstroyed ourselves as humane
- beings, and if we recognize any destruction at all, it is that of our
- environement. We must recognize that we are suffering from a sickeness even
- though it has been repeatedly denied; nevertheless it is, from my point of
- view as a student of human nature, a fact that most people are no longer
- humane beings, but sick persons - a sickness induced by the worship of false
- values which have corrupted the spirit of man and made him the most dangerous
- creature on this Earth. Unless he cures himself of this sickness, can one
- reasonably expect such a creature to behave in a healthy manner? What one
- can expect him to do is to behave destructively, and a good deal of the time
- to be unaware of the fact that he is doing so.
-
- Hence, to the question, "How might human beings react to the discovery of
- life beyond Earth?" I would answer: "Don't wait until that life is
- discovered, but prepare yourselves for the discovery by becoming what you
- ought to be, by realizing your evolutionary destiny, which is to live as to
- live and love were one." And what is love? It is the ability to confer
- survival benefits in a creatively enlarging manner upon the other. And what
- is health? It is the ability to love, to work, and to play. If we will
- begin on such a a program of rehabilitation, we may be able to respond to
- the discovery of life beyon Earth in an enhancing manner.
-
- We have landed on the Moon. It might not be such a bad idea if we tried
- landing on Earth. When asked by a European inquirer what he thought of
- Western civilization, Gandhi paused awhile, and wrly smiling, replied, "I
- don't think it would be such a bad idea."

- QUESTIONS FROM THE FLOOR
-
-
-
- QUESTION:
-
- Communications between ourselves and other civilizations can be considered
- in general in two basic categories. One is a sort of passive communication
- in which we receive information from other beings; we must sit there and
- compile it and perhaps eventually sort it out. And the other is an active
- communication, in which we ourselves can try sending signals. And as far as
- the active part is concerned, the first step outght to be to construct some
- sort of signal that would be identifiable as to the fact that we were
- intelligent beings. But beyond that, as Carl Sagan said, these people are a
- lot more intelligent than we are. The next step would be to send out one
- piece of information that would characterize our society. Since they are
- probably more intelligent or advanced than we, deep consideration should be
- given to just precisely what piece of information should be sent out,
- because the wrong characterization of our society, or the wrong
- interpretartion of it, could be quite damaging in the long run.
-
- SAGAN:
-
- I do not think it is quite as urgent to send as to receive, which may be a
- paraphrase of a Biblical passage. Also, I again would want to stress that,
- willy-nilly, we have been sending, so your remarks are most properly directed
- to the FCC. The image of our society, which is garnered at some place 30
- light years out, is the image you get by turning on the lat-night tube. So if
- you are worried about sending out the wrong message, you have every reason to
- be worried.
-
- BERENDZEN:
-
- Let me mention something that I would hate to pass without adequate
- discussion. Is it possible that if we detected a signal from space, it would
- have the dramatic, beneficial effect on mankind to bringing us together?
-
- SAGAN:
-
- Well, I alluded to that before. I think chances of that happening are very
- great, because as soon as it is clear that there is somebody else out there
- and they are smarter than us and they are different from us, then the
- differences between the various slight subsets of mankind which people are
- spending a lot of time worrying about -- those differences I think tend to...
-
- MONTAGU:
-
- Look, we have had someone out there for an awfully long time, whom Dr.
- Stendahl calls "God." I take it he is referring to the Christian God. As an
- antrhoplogist I am aquainted with several hundred gods. And this God is
- supposed to be all wise and all-loving, etc. We seem to have learned very
- little from Him. Why should our communication with extraterrestrial beings
- have a more cohesive effect that the concepts of the Catholic CHurch, for
- example?
-
- SAGAN:
-
- It is a good question. There are many possible long answers, but maybe the
- fastest answer I can give is that there may be some room for doubt about the
- reality of the several hundred gods you were talking about, but once the
- message is received, I think there will be very little room for doubt about
- the reality of the message.
-
- MONTAGU:
-
- But I do not doubt the existence of any of these hundreds of Gods! I believe
- anything you believe to be real is as real as it could possibly be, even
- though it's unreal.
-
- SAGAN:
-
- That's why you have such an exemplary moral character!
-
- --------
-
- QUESTION:
-
- I would like to direct a question to Carl Sagan. Professor Wald has raised
- the issue of the control of technology. Now the conference that took place in
- Soviet Armenia was a mutual conference between two great powers. Professor
- Morrison has raised the possibility that a tremendous corpus of knowledge can
- come wafting down from outer space. Suppose that this comes into an American
- facility in Puerto Rico, technology that would enable us to dominate this
- world. Suppose it comes into a Soviet facility in Armenia. What exactly would
- be the international body that would monitor these signals from outer space,
- assuming that this civilization that we would be communicatin with is more
- advanced and would be giving us tremendous technological knowledge? What is
- to guarantee that one of the existing nation-states does not monitor it and
- use it as we have used our technology in the past?
-
- SAGAN:
-
- Very good question. Fortunately, I think it has a quick answer. The answer
- has to do with time scale and beamwidth. As Phil Morrison stressed, and he
- *must* be right, the time scale to learn a new technology from such a message
- must be long - decades perhaps. No ine is going to say, "Put tab A into slot
- B." You want to think a little before you do that. You do not say, "Oh, yess,
- sir; right in." You want to understand what is happening first. So things
- will move slowly if there is a new technology involved. That is the first
- part of the answer.
-
- The second part is that the Earth is tiny compared to the size of the beam.
- Therefore, all of the Earth -- not just Armenia and Puerto Rico -- but also
- the Netherlands and Australia and Ghana and all the other countries are going
- to be able to pick up the same message. Therefore it makes no sense at all
- for one nation to classify the message. It is like classifying the Sun. It
- makes no sense., YOu can do it if you want, but it does not help.
-
-
- --------
-
- QUESTION:
-
- The assumption is that these messages are now passing through othe solar
- system. We have to assume that we are just not receiving them now. If you
- know that if you are the first country to discover this body of knoweldge,
- you'll have a major advantage, then might not...
-
- SAGAN:
-
- The you have to imagine a scenario in which there is a large, secret radio
- telescope that is working for a century on a given problem and word never
- leaks out. I myself find that difficult to believe, esp[ecially since the
- total number of radio astronomers in the world is extremely small, and all of
- them know each other. Also, I believe that the community of scientists on
- this issue is such that it is impossible for such a discovery to be made
- without it being known on an international scale.
-
- WALD:
-
- Once again, all the nations will be listening in equally, provided they have
- equally big radio telescopes. So we will have a radio-telescope race, and God
- help the nation that has a somewhat smaller radio telescoper that the others.
- As for the community of world science, this is the firt time I have heard
- that it covers weapons technology.
-
- SAGAN:
-
- We are not talking about weapons technology.
-
- WALD:
-
- But this can be converted into weapons technology.
-
- SAGAN:
-
- Sure, but it starts out by saying, "A,B,C,D...." Do you say, "Let's classify
- the alphabet and maybe the next thing that comes in will be how to build a
- better weapon"? I just cannot see it.
-
- WALD:
-
- But that is the way nuclear energy appeared. One did not know what to do with
- it or how to handle it, so a few nations with the technical facilities and
- the wealth got themselves atom bombs.
-
- ---------
-
- QUESTION:
-
- The assumptian has been up to now that any message received will be via some
- electromagnetic wavelength. It would seem to me that this is a very naive
- assumption to make in view of the fact that the senders, as has been stated
- repeatedly, will be far more intelligent that us, and may have access to
- means of which we are completely unware.
-
- BERENDZEN:
-
- Excellent point. Phil, you have given much though to this. Would you
- respond?
-
- MORRISON:
-
- If the thousand-megacycle bands of radio are not the best ones, even though
- they are easily accessible, then there is no question about it, we will find
- nothing from this search. The only trouble with that kind of argument is that
- it could be put forward at any time, no matter what technology is presently
- available. You can always say there is something we do not know that 10 years
- from now will be much better understood. Therefore I think if you say this,
- your inaction is guaranteed; then you surely will never make the search.
-
- And it can be the other way around. When it turns out after sober thought
- that you find yourself easily able to listen by some means that looks
- plausible, that will in fact carry the message, then try it. I believe there
- is a society of these groups, not just one. There are probably very many. If
- there were only one, we would likely have no hope of finding it. But there
- are probably thousands, maybe as many as million. They probably have already
- had much experience at finding new civilizations and bringing them into the
- network. If so, they will understand that they should not start with the most
- advanced device; if you want to make friends with some new group smewher, you
- do not set up color TV stations. You might wave a flag or beat a drum. You
- know you have access to those channels.
-
- SAGAN:
-
- I would look at it like this. Suppose that we were a tribe in some isolated
- valley in, say, New Guinea, where we communicate with our neighbors over in
- the next valley by runner and by drum. And we are asked to imagine an
- advanced civilization thousands of miles away. How would they communicate? I
- would say, "Oh, probably by very fast runners or enormous drums that beat
- very loud." In fact, there is a vast international radio and cable traffic
- going around such people, and over them, and through them, and they would not
- know about it. But that radio and cable traffic is not intended to talk to
- the inhabitants of that isolated valley. It is intended for coversation
- between technologically more sophisticated beings. If we wanted to talk to
- them, then we would need to use the technology of the local civilization.
-
- And I would imagine that if an advanced civilization wanted to talk to us,
- they would say, "Those guys must be extremely backward. Let's go to some
- ancient museum and pull out ... what do you call it?... one of those radio
- telescops, and beam it at them." But meanwhile they would use for their own
- purposes whatever it is they use -- gravity wavers, or neutrinos, or
- tachyons, or whatever is the fast, high-informational channel.
-
- ---------
-
- QUESTION:
-
- Do you think it is more likely that the message we will intercept will be
- going back and forth between two members of a soceity or will it be an
- exploratory one, aimed just as us?
-
- MORRISON:
-
- If we get the message at all, it is not likely to be just a chance beam that
- crosses us -- that is very unlikely.
-
- ---------
-
- QUESTION:
-
- But it will have a wide beamwidth, as was pointed out.
-
- MORRISON:
-
- If it is a wide beam, then the beam would be include probably just exactly
- these search channels we are talking about. If it is not that, it will be
- very hard to find a message that has not been designed to be easy to read. If
- it is just high-speed chatter on some frequency we cannot use, I do not know
- if we are ever going to find it.
-
- SAGAN:
-
- Wide beam compared to the size of the Earth but narrow beam compared to how
- many stars you are going to pick up.
