much is known, it is fairly clear that the model of the logic-machine is not only wrong but mischievous. There are people who profess to believe that man can live by logic alone. If only they say, men developed their reason, looked at all situations and dilemmas logically, and proceeded to devise rational solutions, all human problems would be solved. Be reasonable. Think logically. Act rationally. This line of thought is very persuasive, not to say seductive, 1. It is astonishing, however, how frequently the people most fanatically devoted to logic and reason, to a cold review of the "facts" and a calculated construction of the truth, turn out not only to be terribly emotional in argumentation, but obstinate any "truth" is "proved"——deeply committed to emotional positions that prove reek-resistible to the most massive accumulation of unsympathetic facts and proofs.

2. If man's mind cannot be turned into a logic-machine, neither can it function properly as a great emotional sponge, to be squeezed at will. All of us have known people who gush as a general response to life——who gush in seeing a sunset, who gush in reading a book, who gush in meeting a friend. They may seem to live by emotion alone, but their constant gushing is a disguise for absence of genuine feeling, a torrent rushing to fill a vacuum. It is not uncommon to find beneath the gush a cold, analytic mind that is astonishing in its meticulousness and ruthless in its calculation.

Somewhere between machine and sponge lies the reality of the mind——a blend of reason and emotion, of actuality and imagination, of fact and feeling. 3. The entanglement is so complete, the mixture so thoroughly mixed, that it is probably impossible to achieve pure reason or pure reason or pure emotion, at least for any sustained period of time.

4. It is probably best to assume that all our reasoning is fused with our emotional commitments and beliefs, all our thoughts colored by feelings that lie deep within our psyches. Moreover, it is probably best to assume that this stream of emotion is not a poison, not even a taint, but is a positive life-source, a stream of psychic energy that animates and vitalizes our entire thought process. 5. The roots of reason are embedded in feelings——feelings that have formed and accumulated and developed over a lifetime of personality-shaping. These feelings are not for occasional using but are inescapable. To know what we think, we must know how we feel. It is feeling that shapes belief and forms opinion. It is feeling that directs the strategy of argument. It is our feelings, then, with which we must come to honorable terms.

rarely get caught, because the lies we tell are usually little ones: "I got stuck in traffic." "That color looks good no you." "I was just about to call."

But even the smallest fib may soon be systematically exposed, at least in the virtual World. Researchers at several universities are developing software that can detect lies in online communications such as instant messages e-mails and chatrooms. The ability to spot "digital deception", as researchers call it, has never been more crucial. Today, much of our business and social life is conducted online, making us increasingly vulnerable. White collar criminals, sexual predators, scammers, identity thieves and even terrorists surf the same Web as the rest of us.

Conventional lie detectors look for physiological signs of anxiety--a bead of sweat or a racing pulse--but online systems examine only the liar's words. "When we're looking at Ianguage, we're looking at the tool of the lie," says Jeff Hancock, all assistant professor of communication and a member of the faculty of computing and information science at Cornell University.

Hancock, who recently received a $ 680, 000 grant from the National Science Foundation to study digital deception, says there is a growing body of evidence that the language of dishonest messages is different than that of honest ones. For example, one study led by Hancock and due to be published this spring in Discourse Processes found the deceptive e-mail messages contained 28 percent more words on average and used a higher percentage of words associated with negative emotions than did truthful messages. Liars also tend to use fewer first-person references (such as the pronoun "I") and more third-person references (such as "he" and "they"). This may be the liar's subconscious way of distancing himself from his lie.

More surprising, Hancock and his colleagues have observed that the targets of liars also exhibit distinctive language patterns. For instance, people who are being deceived often use shorter sentences and ask more questions. Even though they may not be aware that they are being lide to, people seem to exhibit subconscious suspicions.

To identify the patterns of deceit, Hancock has developed an instant-messaging system at Cornell that asks users to rate the deceptiveness of each message they send. The system has already collected 10, 000 messages, of which about 6 percent qualify as patently deceptive. Eventually the results will be incorporated into software that analyzes incoming messages.

For now, the Cornell researchers are working only with the kinds of lies told be students and faculty. It remains to be seen whether such a system can be scaled up to handle "big" lies, such as messages sent by con artists and terrorists.

Fortunately, the research so far suggests that people lie less often in e-mail than face-to-face or on the phone. Perhaps this is because people are reluctant to put their lies in writing, Hancock speculates. "An email generates multiple copies," he says. "It will last longer than something carved in rock." So choose your words carefully. The internet may soon be rid not only deceit but also of lame excuses.

usted kids? Wrong again. The fact is we are terrible at predicting the source of joy. And whatever choices we do make, we likely later decide it was all for the best.

These are insights from happiness economics, perhaps the hottest field in what used to be called the dismal science. Happiness is everywhere--on the best-seller lists, in the minds of policymakers, and front and center for economists--yet it remains elusive. The golden role of economics has always been that well-being is a simple function of income. That's why nations and people alike strive for higher incomes-money gives us choice and a measure of freedom. After a certain income can, we simply don't get any happier. And it isn't what we have, but whether we have more than our neighbor, that really matters. So the news last week that in 2006 top hedge-fund managers took home $ 240 million, minimum, probably didn't make them any happier, it just made the rest of us less so.

Now policymakers are racing to figure out what makes people happy, and just how they should deliver it. Countries as diverse as Bhutan, Australia, China, Thailand and the U. IC are coming up with "happiness indexer," to be used alongside GDP as a guide to society's progress. In Britain, the "politics of happiness" will likely figure prominently in next year's elections. Never mind that the world's top happiness researchers recently gathered at a conference in Rome to debate whether joy is even measurable.

Why is this all happening now? only in the last decade have economists, psychologists, biologists and philosophers begun cross-pollinating in such a way to arrive at "happiness studies". Harvard psychologist Daniel Gilbert humorously sums up much of the new wisdom in his book "Stumbling on Happiness". He says 24-hour television and the Internet have allowed us all to see more seemingly happy people than ever before. "We're surrounded by the lifestyles of the rich and famous," says Gilbert, "rubbing our noses in the fact that others have more."

of course, the idea that money isn't the real key to happiness isn't new. The 18th-centry British Enlightenment thinker Jeremy Bentham argued that public policy should try to. maximize happiness, and many prominent economists agreed but could not quite embrace the idea. There was just no way to measure happiness objectively.

one of the early revelations of happiness research, from Richard Easterlin at the University of Southern

California, was that while the rich are typically happier than the poor, the happiness boost from extra cash isn't that great once one rises above the poverty line. The reason, says Easterlin, is the "hedonic cycle": we get used to being richer dam quick, and take it for granted or compare it to what others have, not what we used to have. Tums out, keeping up with the Joneses is hard-wired into our brains, thanks to our pack-creature roots.

Though many happiness researchers say "work less, play more" is the formula for happiness, Ruut Veenhoven, a professor at Erasmus University in Rotterdam, suggests otherwise. Hard-working Americans ranks 17th on his list; the hard-vacationing French 39th. Human beings do want a European-style. safety net, but also want freedom and opportunity.

And perhaps our intuitions about happiness should triumph over the fuzzy data, anyway. The economics of happiness has given us a couple of fairly hard and fast roles about well-being-being truly poor is bad, and time with friends and family are good. The good news is that whatever choices we make individually and as societies in the pursuit of happiness there's good chance that they'll seem better in hindsight. Yet another truism of happiness is that "we all wear rose-colored glasses when it comes to our past decision-making," says Gilbert. Today's dreadfu

Monkeys like Allie are just one of many kinds of animals that help improve--or even save--human lives. But not all animals are suited to do every job. Certain animals are "hired" for specific jobs based on their traits, or characteristics. By using different methods of conditioning (training animals to act in a particular way in response to a stimulus, or signal), humans can teach animals toper form. extraordinary tasks.

Throughout history, humans have relied on animals' traits to get certain jobs done. For example, compared with humans, dogs are "far superior at tracking down odors", says Marian Bailey, an animal behaviorist at Henderson State University in Arkansas. That's because dogs have million of olfactory receptors, or smell nerves, in their noses.

For that reason, hunters used dogs to track down prey even in ancient Egypt. Today, dogs my be employed to sniff out illegal substances in school lockers or earthquake victims buried beneath the rabble of the collapsed building or highway.

Primates may not be good sinffers, but they can certainly lend a helping hand--or two. Monkeys are perfect helpmates for quadriplegics, people paralyzed from the neck down who are unable to use their own hands (and legs). Like humans, explains Bailey monkeys have opposable thumbs--thumbs that face the hand's other fingers--so monkeys can pick up objects. Capuchins learn to open doors, clean up spills, and unscrew bottle tops. They can even get a sandwich out of the refrigerator and load your favorite tape into the VCR.

And speaking of VCRs, animals are even helping scientists make a videotape. Jennifer Hurley, an animal researcher at the Long Marine Lab in Santa Cruz, California, is training two sea lions to carry video cameras on their backs to record the natural behavior. of whales.

So how do you get an animal employee to do its job? The answer, career-training. Trainers teach the animals to obey their instructions through a process called conditioning.

Most trainers condition animals by using positive reinforcement, rewarding an animal for doing something correctly, says animal behaviorist Bailey. For example, trainers teach their dogs how to sniff out drugs by hiding a towel with the smell of drags. "Dogs love to retrieve objects so the towel becomes a reward", says Morris Berkowitz, who heads up a canine drug-sniffing program in New York.

After repeating this game of hide-and-seek many times, the dog begins to "associate the odor with a reward", says Berkowitz. When he gives the command, or stimulus, the dog seeks cot drags (it's like learning to study hard for a tests in order to get a good grade as a reward.)

At "Helping Hands--Monkey Helpers for the Disabled", capuchin monkeys are trained twice before being teamed with a disabled human. First, monkeys are placed with a foster family to become socialized to people. For five years, families help the monkeys adapt to a human environment, so the monkeys will trust and enjoy being around people.

Taking the monkeys in when they're four to six weeks old is important, says Bailey. "That's when monkeys normally become socialized to other monkeys," she says.

Second, trainers at Helping Hands train the monkeys to perform. specific tasks to assist a particular person. For example, a monkey may be trained to scratch an itch, or slip a floppy disc into a computer dive. Trainers reward the monkeys by using positive reinforcement, such as food, drinks.
