a model kit for the world

It is in some ways like the ideal of the great romantic love: They are always looking for, but you will not, but at best rough approximations. Often you find yourself starting with what you have, and yet she hangs like a semi-transparent mirage for many generations before us, and we continually seek, for they and the search for it enriches our lives and gives it a hint of a meaning. Many people have gone crazy because of them, committed suicide or were killed. However, it is not a femme fatale, not even a person, it is - the truth.

The urge to understand the world and find out how it works is that people immanent - the earliest age, we crawl around curiously and suck everything in us that makes us understand our environment. The deeper understanding of the world is the evolutionary advantage of us, who are neither particularly fast nor particularly strong, or shipped, has allowed to survive. On the other hand, philosophers early have recognized that we will understand the truth about the world as it is "in reality," never to end.

the one hand, we rely on detection of the things on our feelings. We see not really what "is" an object, but only a construct of our brain because of the sensory stimuli. Let's take for example a red apple, we must be aware that the apple does not really red "is" - we see only red because our brain from the retina to the incoming data on electromagnetic radiation with a wavelength of about 640 nm - 780 nm interpreted as red. The joke is that a red apple is actually anything, not just red - the red wavelengths are indeed the apple just thrown back (and get in our eyes). As the same wavelength is interpreted by a rabbit or a Martian, and whether their concept of "red" corresponds with ours, we do not know - but both are expected in each case a quite different model to build the "truth" about the red apple.

intellectually Also, our knowledge Limits - we humans are simply not smart enough to know "the truth" about the world. Even if, in view of us brought forth by supercomputers or Mars rovers first sounds stupid - the way the world is certainly too complicated for us. Or you can prove to me that we all are not just figures in a giant computer simulation known to our laws of nature, as we know it works? What can we do - and what is the role of science - is to us as in the perception of the red apple to construct a model that fits reality. It does not address, is said, but fit, not contradicts it. A police dog will never understand why he was trained to sniff out drugs in luggage compartments, but it is clear to him - if he does it, there's a treat and some tender loving care by the master. It penetrates the complexity of the world, but he learns to deal with it, so is he good. And in this position, we are ultimately human. The laws of nature, we discover, are nothing more than the law of the dog that there is a drug discovery Chappi a pound.

truth is always subjective, navigating a guide to the world with which we through the maze of being. It does not matter whether someone with a better knowledge (other advanced civilization etc.) has overtaken our model - as long as it works, it is our "truth." A good example is the placebo . If the model in our mind gives us an improvement - it will just be so, then this is our personal truth about the "reality" - even though we have "objectively" just a piece of white sugar eaten in tablet form. In a famous experiment "thought" birds that if they make a certain movement, the machine in her cage donated them food - in fact the machines were their dances matter, but they were tired at the end anyway. Its truth was so different from those of researchers who the weird contortions of the birds laughed, but both views were equal. And therefore, the theory of relativity "objective" might describe a very different way the world than we think - as long as it works, it is our useful placebo, our "truth" that we now do not even know better. But still looking

be constantly on.

The Meaning of Life

Ah yes, the meaning of life ... There are many paraphrases this seemingly profound question - Where do we come from, where are we going? - Or, to put it to Douglas Adams: "The Question of Life, the Universe and Everything". I as a follower of prose Answers to questions poetic think the question is in this form first, and were ambiguous and, secondly, a touch of megalomania out. Miss

course because "meaning" mostly implies that the something whose meaning we seek, was created by someone in an intention out for anything, so has a purpose. "What is the meaning (and purpose) of a computer?" Is thus a valid question. The "sense of the weather," one looks in vain, however. The weather is just there. It is a natural phenomenon, as we are. No one has been created us or we are, even if it sounds disappointing, the product of a process of random selection Mutations of a complex carbon-based molecule. All the miracles accomplished man so far, the symphonies of Beethoven, the relativity theory, the landing on the Moon, to the words of Carl Sagan, "things that hydrogen atoms do when you give them 15 billion years time .

But where does the question of the meaning of life in general? - Well, for thousands of years it was not questioning taken for granted that we were created but somehow, by one or more gods. Created - oh, then surely for a purpose! Life was filled with a mysterious sense, because such a God is not for nothing that makes the effort. And then suddenly - I give the floor here at Steven Weinberg, who puts it excellently added:

"The people considered themselves characters in a cosmic drama: We were created to have sinned, to be redeemed - a very large remember history. Now we know that we are more like actors standing around with no stage directions on a stage, and that nothing else is left here as a bit of drama to improvise there a little comedy. "

Sigmund Freud had already had a similar epiphany, and developed the theory of the "insults to humanity . After that the first (Copernicus) the humiliation that people suddenly had to realize, not the Earth was the center of the universe, but an insignificant bits of stone somewhere on the outskirts of the Milky Way. The second insult came from Darwin, who made us clear how the man could arise naturally, without divine breath from a common ape-like ancestors. I think, therefore, is the eternal question of the meaning of life: the past, the sense because of the religious influence of course available and easy to find at the pastor / priest / shaman of your trust. Is man but disenchanted as a mere upgrade of the monkey, so it looks (perhaps unconsciously) - For a replacement for the lost throne - and invents a meaning of life, is not there, because there is nobody who can give us this "objective" sense.

What does not prevent us to live the life meaningful, to try to understand the world and to do good. This sense - or rather content - we must give life but even so he is solely in our hands.

you are me

What happens when you show an infant's tongue? - The chance is high that the child then returned the favor. If you a monkey that sings? - The monkey could agree with (see left). If you watch another accidentally touches a hot stove? - Man pulls a pained expression his hand to the body. And when you see sick people to put their own immune system on alert .

The cause of these feelings and reactions is the same: it is the only recently discovered so-called mirror neurons in our brain. Some describe it as the most important discovery in the Neurophysiology of late. In simple words there are nerve cells in our brain that simulate all the actions, feelings and moods of those around us. Diego Maradona to see us when dribbling towards goal, in our brains is a virtual Copy of the striker created. And we risk not only "a little bit with him," no, we are actually in that moment, Diego Maradona. Let us see how someone else is pricked with a needle, there is a corresponding response in our brains out, so that only the absence of pain we must be calm in order to show no defensive or escape behavior. Simply by watching so inevitably we put ourselves into the other person.

Why bother? - It's simple: because we understand our fellow human beings better. Evolution has provided us with actual brain cells that are responsible for empathy (the neuroscientist VS Ramachandran calls they like to publish also " Dalai Lama neurons "). Man as a social system from the ground up, they need to facilitate the interaction with others. He has the inner lives of others, their intentions, emotions, etc. guess not by logical conclusions from their external behavior, he feels just as if it were his own! Significantly, even in people with autism, people who have problems interacting with others, a weak mirror neuron activity been established. Even doctors' protect themselves "by a reduced sensitivity of the ongoing management of pain of others.

The less direct experience Empathy for another person but is just tied to immediate perception. We see a helpless people on the streets, we have a greater need to help him than when it comes to millions of starving Africans is that we have never seen. clear evolution from a theoretical point of view: We should worry only about the immediate past members of the tribe who were related to us many times, and not to people who do not concern us. Therefore agree in the famous trolley dilemma most respondents, a human sacrifice in an indirect way, by turning the switch, but not directly by pushing down from the bridge. The Dalai Lama neurons, to make his suffering as our own, to prevent it creates a hand.

Asians have traditionally distanced themselves from the idea of the individual. For it is one of the community, the association to which one belongs to, the unit under Miscellaneous. Mirror neurons give them right in a way. When I interact with others, I flipped on their heads and thus become a part of them. The boundaries between the individual and "the others" are resolved to some extent. It is, as long as you come into direct contact with other, never "alone". I'm also a bit of you, and not by deductive conclusions, but quite direct - thanks to the mirror in my brain.
