				First, a message for you humans out there, who happen to be reading 
			this right now.
 
 As many of you know, I approach the topic of 
				non-human intelligent 
			life from two perspectives. As an author using fiction to explore 
			notions beyond today's science, I explore the forms and motivations 
			that alien beings might assume, from outlandish to eerily familiar. 
			I am also involved in the same subject at the scientific end, 
			participating in the International Astronomical Union's Subcommittee 
			on Bio-astronomy.
 
 SETI -- the Search For Extra-Terrestrial Intelligence -- can be a 
			difficult and confusing topic, straddling the concerns of everyone 
			from sober researchers to politicians to dreamers hoping that alien 
			contact may somehow save humanity "from ourselves"
 
 The good news? This widely-shared interest seems to reflect an eager 
			expansiveness of spirit and willingness to entertain fresh ideas far 
			beyond our mundane lives. The bad news is that our imaginations have 
			forged so far beyond the sparse data on hand that things can get 
			rather silly at times. Take those paranoiac rumors that the U.S. 
			Government has kept an alien spaceship stashed away, studying it for 
			decades. (Hmm... so it's been studied incessantly by three 
			generations of our brightest engineers... without any of them 
			blowing the whistle by now? Right.)
 
 Nearly all SETI researchers agree that the public should be told 
			right away, after any radio contact is confirmed. Most have 
			initialed or signed a "protocol", agreeing in advance to principles 
			of openness -- e.g. that the contents of any message must not be 
			kept secret. Still, there is disagreement over details. For example; 
			though no signal from an interstellar civilization has ever been 
			confirmed, controversy rages over whether or not we should reply, 
			when and if someone does pick up such a message. Should our openness 
			policy extend to announcing the exact sky coordinates of the signal 
			source, and the frequency extraterrestrials are using?
 
 Many SETI researchers think any confirmed signal will automatically 
			result in a cacophony of replies, sent at once by any nation or 
			interest group with the technology to shape a radio signal. Everyone 
			from Ayatollahs to the Mafia, from science fiction fans and Klingon 
			language scholars to recently-discovered Amazon tribes will begin 
			beaming appeals and tracts at a particular point in space, almost 
			the very next day.
 
 A minority in the SETI community thinks it would make better sense 
			not to reply right away. Waiting a decade or so, to gather data and 
			discuss the ramifications, might seem more prudent than instantly 
			hollering into the unknown. Just look at the history of contact 
			between human cultures, in our recent past. The less technologically 
			advanced nearly always suffered.
 
 True, aliens may be a lot nicer than 
				18th Century European 
			colonialists were. But would you bet our future on it? Our limited 
			experience suggests that it's sensible for the weaker party to be 
			cautious, and concentrate on listening before shouting.
 
 As I've written elsewhere, the apparent emptiness of the cosmos 
			seems to suggest that something may be dangerous about our galaxy.
 
 
			But in fact, it seems that a message to aliens is about to be sent, 
			whether we like it or not! This one doesn't involve expensive 
			transmitters or engravings on a space probe. There won't be any 
			extravagant shouting into interstellar space, because this message 
			will go out swiftly and cheaply... on the Internet. Toronto academic 
			Allen Tough and 80 colleagues plan to issue an appeal via the World 
			Wide Web, inviting extraterrestrial intelligent life-forms to please 
			say hello.
 
 Professor Tough's operating assumption -- and hope -- is that a 
			smart probe from some advanced civilization may already be 
			monitoring our telecommunications. Perhaps it has resided in our 
			solar system for centuries or longer. Or maybe it was drawn in 
			recently, by radio signals emanating from our little world. Either 
			way, if it has kept up with the increasing sophistication of our 
			signals, it may be monitoring the Web right now.
 
 In other words "they" may already be here, in a manner of speaking. 
			They just haven't chosen to speak up.
 
 Dr. Tough hopes to do something about this possibility. His web site 
			is designed to draw the attention of any alien "lurker" (or lurkers) 
			out there. He hopes the content of the hello page will persuade the 
			alien to abandon its present policy of silence. Perhaps the right 
			kind of invitation will sway ET (or ET's probe) to phone us.
 
 
 
			All right, let's go along with this assumption. Before crafting any 
			such message, we should ask -- what do we already know?
 
 The one clear fact about any purported lurking space alien or probe 
			is that most of us are presently unaware of its existence. It's been 
			silent, so far. At least to a majority of human beings.
 
 The most likely conclusion to draw from this sole fact? Why, that 
			such a lurker probably doesn't exist!
 
 Still, that's not the only possible explanation. My 1983 short story 
			-- "Lungfish" -- explored this very situation, coming up with a 
			number of possible alternatives. I admit, the subject fascinates me.
 
 So let's stretch our imaginations! In drafting my contribution to 
			Dr. Tough's site, committed to electronic form and cast into space, 
			here's what I came up with, so far --
 
 
 
			To any alien lurkers prowling or waiting out there -- if you are 
			reading this, perusing the electronic communications network of our 
			lonely little planet, please pick whichever of the following applies 
			to you, and ignore the rest.
 
				
				1. If you've 
				spent years monitoring our radio, our television -- and now our 
				internet-- and the reason you haven't answered is that you are 
				afraid of the rash or violent behavior you see depicted in our 
				media... please be reassured! 
 True, many of our movies and TV stories portray distrust, 
				selfishness, hot tempers and extreme violence. But you should 
				know that, in fact, very few of us ever experience events as 
				disturbing those you see in our dramas. Most of us actually 
				dislike such violent traits in ourselves. By exploring these 
				ancient feelings, inherited from a dark past, we hope to 
				understand them better.
 
 Also note: in a vast majority of these stories, the "loser" 
				tends to be whichever person or group was more aggressive or 
				intolerant at the start. Doesn't that say something about our 
				moral heading?
 
 The same holds for non-fiction. Despite news reports depicting a 
				riotous world, the actual rate of mayhem in human society has 
				declined dramatically during the last five decades, if measured 
				on a per capita basis. Look up the actual numbers! More than two 
				thirds of all humans living today have never personally 
				witnessed war, mass starvation or major civil unrest -- an 
				unprecedented fraction who have been allowed to improve their 
				lot in peace. Many ancient bigotries and cruelties have been 
				lessened, or have at least been put in bad repute. And with the 
				spread of education, many far greater advances now seem 
				possible.
 
 True, these achievements are still woefully unfinished. They 
				leave tremendous amounts for us yet to do, in working toward a 
				just and mature civilization. But they are clear signs of 
				progress and overall good will by a majority of our species.
 
 Despite the self-critical news reports and flamboyantly 
				exaggerated "action" stories you may have watched, please be 
				assured that most human beings are calm, nonviolent people who 
				treat strangers well. Many millions of us would be thrilled to 
				meet you, and would expend every effort to ensure that peaceful, 
				honest visitors are made welcome.
 
 
				
				2. If you've monitored our TV, radio -- and now our 
				internet-- and the reason you haven't answered is that you are 
				damaged, or otherwise incapable of sending, please be assured 
				that we are on our way!
 
 We have begun, slowly, to explore our solar system. If you are 
				not too deeply hidden, we should come upon you in the due course 
				of time. We hope to make peaceful contact and learn your needs. 
				If you are incapacitated, and our explorers feel you mean no 
				harm, they will surely render you whatever aid they can, and 
				call on the resources of our planet to bring more. Try to find a 
				way to let us know where you are and what you need.
 
 If you are lost and far from home, welcome to our small part of 
				this enormous universe. We offer whatever warmth and shelter we 
				have to share.
 
 
				
				3. If you've monitored our TV, radio -- and now our 
				internet-- and the reason you haven't answered is that you see 
				us as competitors, we ask that you reconsider.
 
 In our long, slow struggle to achieve some degree of decent 
				civilization, humans have slowly learned that competition and 
				cooperation aren't inherent opposites, but twins, both in nature 
				and in advanced societies. Under terms that are fair, and with 
				goodwill, even those who begin suspicious of each other can 
				discover ways to interact toward mutual benefit. (Use the Web to 
				look up the concept of a positive-sum game, where "win-win" 
				solutions bring success to all sides.)
 
 Surely there are ways that humanity -- and other Earth species 
				-- should be able to join the cosmos without causing injury to 
				your legitimate aims. Remember, most stable species and cultures 
				seem to benefit from a little competition, now and then! So 
				please answer. Let's talk about it.
 
 
				
				4. If you've monitored our TV, radio -- and now our 
				internet-- and the reason you haven't answered is that you are 
				waiting for us to pass some milestone of development... well 
				then, how about a hint? Pretty please?
 
 If that milestone is for us to assertively ask for membership in 
				some society of advanced sapient beings, please take this 
				paragraph as that asserted step, taken by one subgroup of 
				humanity, hoping to serve the interests of all our planet. 
				Please give us the application forms... and all information 
				(including costs and benefits) that we may need in order to make 
				a well-informed decision about joining.
 
 
				
				5. If you've been monitoring our TV, radio -- and now our 
				internet-- and the reason you haven't answered is that you are 
				studying us and have a noninterference policy, let us now say 
				that we understand the concept.
 
 Observing more primitive species or cultures can seem to demand 
				silence, at least for a time, in order for the observer not to 
				interfere with the subject's natural behavior. Your specific 
				reason may be scientific detachment, or to let us enjoy our 
				"innocence" a while longer, or perhaps because we are unusual in 
				some rare or precious way. In fact, we can imagine many possible 
				reasons you might give for keeping the flow of information going 
				in just one direction -- from us to you -- and never the other 
				way. Similar rationalizations are common among human beings.
   
				Of course, some 
				humans might respond that it was cruel of you not to contact us 
				during the Cold War, when news of contact might have prodded us 
				away from our near-brush with nuclear annihilation. Or that you 
				should have warned us of the dangers of ecological degradation. 
				Others might argue that it's heartless to withhold advanced 
				technologies that might help solve many of our problems, saving 
				millions of lives. 
 In fairness, some other humans would argue that we have won 
				great dignity by doing it all by ourselves. They take pride in 
				the fact that we show early signs of achieving maturity by our 
				own hard efforts, alone. If your reason for silence is to let us 
				have this dignity, that might make sense... so long as it isn't 
				simply an excuse, a rationalization, to cover more selfish 
				motives.
 
 To interfere or not? It is a moral and scientific quandary that 
				you answer by silently watching, to see if we'll solve our 
				problems by ourselves. (Perhaps we are doing better than you 
				expected?) Who knows? Your reasons may even have great validity.
 
 Still, if you continue this policy, you cannot expect profound 
				trust or gratitude when we finally overcome our hardships and 
				emerge as star-faring adults without help. Oh, we'll try to be 
				friendly and fair. But your long silence will make it hard, at 
				least at first, to be friends.
 
 We understand cold-blooded scientific detachment. But consider 
				-- the universe sometimes plays tricks on the mighty. In some 
				distant age, our roles may be reversed. We hope you'll 
				understand if our future stance toward you is set by your 
				past-and-present behavior toward us.
 
 
				
				6. If you've monitored our TV, radio -- and now our 
				internet -- perhaps you have a policy of noninterference for a 
				different reason... in order to spare us and our culture from 
				some harm that might come as a result of contact.
 
				  
				
				An erosion of 
				our sense of free will? Or our sense of having a high culture? 
				We can understand this notion, too. Certainly the history of 
				first contact between human cultures tells that the one with 
				lower technology and sophistication often suffered ill effects.
				
 If mercy motivates your reticence, we grasp the concept. Yet, 
				this provokes a question -- are you absolutely sure? Can you be 
				certain we're so fragile? Is it possible you might be mistaken? 
				Or (again) perhaps rationalizing a decision that you made for 
				other reasons?
 
 Maybe you should test it by contacting small groups of humans -- 
				perhaps via the internet -- to explore matters that concern you. 
				This will be surprisingly easy and safe, since you can make your 
				enquiries in the form of email letters, or by participating 
				anonymously in online discussion groups. You can even call 
				yourselves by your real names! Everyone on the discussion group 
				will simply assume you are eccentric human beings, using 
				internet pseudonyms to play-act as aliens! Any awkwardness with 
				our language will be taken as another part of your act.
 
 On some sites, your overtures will be dismissed. Elsewhere, 
				bright individuals will gladly play along, engaging you in 
				conversation with lively enthusiasm, pretending to believe you 
				are alien and discussing your concerns for the sheer 
				intellectual joy of doing so. Anyway, you'll get to taste the 
				diversity of human thought, plus a chance to reconsider your 
				assumptions.
 
 Of course, it's possible that you are already doing this and 
				testing us, perhaps by posing as eccentric participants in some 
				of today's internet discussion groups... or possibly by writing 
				intriguing science fiction stories under a pseudonym, to tease 
				our imaginations.
 
 Perhaps you even lace these works with special clues that can 
				only be deciphered by purchasing and carefully reading every one 
				of the purported author's books.
 
 In hardcover, yet.
 
 
				
				7. If you've monitored our TV, radio -- and now our 
				internet-- and the reason we don't know it is that you are 
				already in contact with one or more human sub-groups -- perhaps 
				a government or clique of individuals-- please consider the 
				following.
 
 Human beings have discovered that secrecy is seldom an effective 
				way to create or conduct good policy. It can have many temporary 
				uses. But over the long run, we appear to make our best and most 
				creative decisions -- and commit the fewest errors -- in 
				situations of openness.
 
 The groups or governments you converse with may claim that there 
				are good reasons to keep Contact secret from the public. It is 
				even conceivable that such reasons have short-term validity. But 
				small groups of humans are also notorious for rationalization -- 
				elites have always claimed that the masses are too stupid or 
				fragile to understand. After all, this helps justify their 
				special position in society. Such rationalizations can be 
				self-sustaining, far beyond their initial usefulness.
 
 We suggest you check this out by using our internet in the 
				manner described above (in section # 6). You might join some 
				discussion groups. Apprise them of the supposed reasons for 
				secrecy -- under the guise that you are just another human, 
				pondering an abstract notion. If most or all of the participants 
				disagree with those reasons, you may find it's time to 
				re-evaluate your policy, and make yourself known to the rest of 
				humanity.
 
 
				
				8. Let's suppose you've monitored our TV, radio -- and 
				now our internet-- and the reason you haven't answered is that 
				you enjoy watching. Perhaps you draw entertainment from our 
				painful struggles to survive and grow. Worse, you may be 
				profiting by pulling our cultural, scientific and artistic 
				riches off the internet, without seeing any need to reciprocate 
				or pay for them.
 
 In that case, there is a word for what you are doing. It's 
				called stealing.
   
				Stop it now. We 
				assert ownership over our culture, and a right to share it only 
				with those who share in return. In the name of whatever law or 
				moral code applies out there, do not take without giving or 
				paying in return. 
 The same holds, double, if you've been responsible for any of 
				our current problems. For example, if you are behind any 
				so-called "UFO sightings."
 
 The group authoring this web site consists mostly of SETI 
				scholars who don't believe in UFOs. But millions of humans do 
				believe. The reports they circulate describe purported visitors 
				behaving in ways that are almost universally secretive and 
				nasty, often downright vicious. Others claim that aliens have 
				meddled in our politics, social structures or even our genes. 
				Again, we in this group don't believe these stories. But if any 
				of them happen to be true, and you are responsible, we ask you 
				to desist at once.
 
 Instead, come forth openly, as honorable visitors should. SETI 
				personnel would be eminently qualified to make the arrangements.
 
 Consider that maliciousness inevitably has consequences. If 
				either of the scenarios described in this section are true, and 
				you still refuse to come forward honestly, then we have just one 
				thing to say to you. Go away! Ask your parents, guardians or 
				other responsible folk to please come and see us instead.
 
 We hereby assert and demand any rights we may have, to appeal 
				for relief or protection from the sort of behavior described 
				above.
 
 
				
				9. Let's say you've monitored our TV, radio -- and now 
				our internet-- and the reason you haven't answered is that you 
				are meddling secretly, in ways that you feel are beneficial to 
				us. If so, please consider what has happened to human 
				civilization, during the last century.
 
 We spent the first half of it plunging headlong into passionate 
				ideologies, giving as much devotion to simpleminded political 
				doctrines -- from communism and fascism to nationalism, 
				fundamentalism and even solipsistic individualism -- as we used 
				to dedicate to religion. Was this partly your doing? Or was it a 
				horrible, adolescent phase that you could only watch us pass 
				through, like an awful fever? In any event, it damn near killed 
				us.
 
 The second half of the century was also a turmoil, featuring 
				many episodes of wrath, violence and ultimate risk.
   
				And yet, across the 
				last five decades, ideologies have gradually lost some of their 
				grip on millions. Instead of oversimplified assumptions or 
				"rules" of human behavior, multitudes began living according to 
				pragmatic systems that allow give-and-take among countless 
				complex citizens. Our media filled with messages promoting both 
				tolerance of diversity and suspicion of central authority. 
				Eccentricity became more acceptable. And while varied forms of 
				hatred still fill many hearts, hatred itself has acquired a 
				growing odor of disrepute. 
 As bigotries slowly give way, there has also been change among 
				our utopian dreamers. Even idealists now admit that there are 
				roles for both competition and cooperation in human affairs. 
				Exhorting people to be good has never worked as well as giving 
				them the freedom to hold each other accountable.
 
 Did you help bring about this recent trend? If so, thanks. We 
				can understand why you would want us not to know of your help. 
				It makes children proud to think they did something all by 
				themselves.
 
 On the other hand, perhaps this recent trend puzzles you. Do you 
				have some ideology that you believe in? Some simple prescription 
				that you think should be just right for us? Something that 
				worked for your species, and now you hope to push on us "for our 
				own good"?
 
 If so, we suggest you reconsider. Nearly all the positive things 
				we've accomplished lately came about by abandoning simplistic 
				formulas and learning to embrace our complexity instead. Please 
				look up our recent scientific discoveries concerning emergent 
				properties, complexity theory and related matters. (a good start 
				might be Kevin Kelly's book, 
				
				Out Of Control.) Then join some of 
				the best discussion groups, as recommended in items 6 & 7 above. 
				Perhaps we can guide you to a better understanding of our 
				intricate and sometimes perplexing natures.
 
 In the meantime, please stop interfering with things you do not 
				understand.
 
 
				
				10. All right, let's suppose you haven't answered because 
				the universe is horribly dangerous. For instance, perhaps radio 
				transmissions tend to be picked up by "berserker" 
				world-destroyers, sent to wreck burgeoning civilizations, as 
				soon as they rear up and speak.
 
 Well, you could have warned us, no? But then, any warning might 
				expose you, and besides, by now we must have already poured out 
				so much bad radio and television that it's already too late. Is 
				a great big bomb already headed our way, to punish us for 
				broadcasting Mister Ed?
 
 In that case, maybe you could spare us some battle-cruiser 
				blueprints and disintegrator-ray plans? Some spin-dizzies and 
				Alderson Field generators would come in handy.
 
 Do try to hurry, please.
 
 
				
				11. I guess we could have stopped at ten options. But 
				that would have been terribly parochial and narrow minded, 
				revealing a chauvinistic cultural bias in favor of beings with 
				five digits on each of merely two hands. So, for all you lurkers 
				out there who use base eleven math and such, here's a final 
				hypothesis -- that you've monitored our TV, radio -- and now our 
				internet -- and the reason you haven't answered is that you are 
				weird.
 
					
					
					Are you waiting until the Earth evolves a more physically 
				attractive sapient race, more like cockroaches? 
					
					Do you stare down at our extravagant road systems and imagine 
				that automobiles are the dominant life form? 
					
					Are you afraid that letting us onto the Galactic Internet will 
				unleash torrents of spam-advertising and pornography? 
					
					
					Perhaps you think we humans all look great when we're old, and 
				galactic-level immortality technologies would leave us with 
				yucky-looking smooth skin for centuries, so we're better off 
				without them?  
			Maybe you have an excuse 
			like the following one, sent in by a member of a SETI-related 
			discussion group:  
				
				"Yes, we have been 
				monitoring your earthling communications, but we cannot respond 
				yet. The Edict of Knodl states that all first contact situations 
				be initiated only during the High Season of Jodar, which on our 
				calendar does not begin for another 344 years. Sorry, but your 
				first radio transmissions reached us just nine years too late 
				for the last one, and the Lords of Vanathok do not look kindly 
				upon violations of the Edict.  
				  
				This may sound like we're a bunch 
				of close-minded religious zealots, but I think you need to get 
				out and see the rest of this galaxy cluster before you make a judgement like that. All praise Knodl, and may his seven 
				tentacles protect you from harm"  
			If your reason is 
			something like that... or if you take pride in some other special 
			weirdness... well, all I can say is just you wait until we get out 
			there. 
 You think you've seen weird? We have beings down here called 
			Californians!
 
 They'll show you a thing or two about weird....
 
 
 
			Enough. This message is now finished... for the time being, at 
			least. Take it for what it's worth, you alien skulkers out there. 
			Meanwhile, I now turn my attention back to the humans who are 
			reading this... real people who buy Science Fiction stories and help 
			pay my bills. In other words, folks truly worthy of my time and 
			attention.
 
 Over and out... for now.
 
 
 
				
				Hello again, fellow humans.
 
 Of course what I've just shown you above is just a sampling of 
			potential reasons why alien lurkers might not openly say hello. Can 
			you think of still more hypothetical reasons why living or machine 
			entities, already prowling in nearby space, might detect us and yet 
			not choose to make contact? Reasons that are consistent with our one 
			firm fact? The fact that a majority of contemporary human beings 
			aren't presently aware of contact with extraterrestrials.
 
 Again, the most likely explanation is that there is no alien space 
			probe lurking in our solar system, soaking up our radio and web 
			traffic while listening silently. If extraterrestrial intelligence 
			exists, it probably lives much too far away.
 
 Indeed, a stronger supposition is that we may be the ones who will 
			venture forth and rescue others from isolation in this dauntingly 
			vast cosmos. We have the brains, the guts, the potential... and the 
			dream.
 
 If that does become our destiny, I hope we'll find good reasons to 
			behave better than some of the scenarios I described above.
 
 Ultimately, this topic is interesting and important, but it's not 
			the most important thing of all. That happens to be the business of 
			solving today's problems and achieving our potential as a species. 
			Because like it or not, we are probably going to have to do it 
			alone. It's a stark and lonely challenge... and one I think we're up 
			to handling.
 
 Have we finished discussing this issue? Not by a light year! After 
			all, whenever humans discuss the possible nature of alien minds, 
			what we are really talking about is ourselves.
