Carl Sagan


I went to the librarian and asked for a book about stars …And the answer was stunning. It was that the Sun was a star but really close. The stars were suns, but so far away they were just little points of light …The scale of the universe suddenly opened up to me. It was a kind of religious experience. There was a magnificence to it, a grandeur, a scale which has never left me. Never ever left me.

2001


KUBRICK: It's not a message that I ever intend to convey in words. 2001 is a nonverbal experience; out of two hours and 19 minutes of film, there are only a little less than 40 minutes of dialog. I tried to create a visual experience, one that bypasses verbalized pigeonholing and directly penetrates the subconscious with an emotional and philosophic content. To convolute McLuhan, in 2001 the message is the medium. I intended the film to be an intensely subjective experience that reaches the viewer at an inner level of consciousness, just as music does; to "explain" a Beethoven symphony would be to emasculate it 
by erecting an artificial barrier between conception and appreciation. You're free to speculate as you wish about the philosophical and allegorical meaning of the film -- and such speculation is one indication that it has succeeded in gripping the audience at a deep level -- but I don't want to spell out a verbal road map for 2001 that every viewer will feel obligated to pursue or else fear he's missed the point. I think that if 2001 succeeds at all, it is in reaching a wide spectrum of people who would not often give a thought to man's destiny, his role in the cosmos and his relationship to higher forms of life. But even in the case of someone who is highly intelligent, certain ideas found in 2001 would, if presented as abstractions, fall rather lifelessly and be automatically assigned to pat intellectual categories; experienced in a moving visual and emotional context, however, they can resonate within the deepest fibers of one's being.

A religião secular do século XX



Marxist eschatology actually mimicked Christian doctrine. In the beginning, there was a perfect world with no private property, no classes, no exploitation, and no alienation – the Garden of Eden. Then came sin, the discovery of private property, and the creation of exploiters. Humanity was cast from the Garden to suffer inequality and want. Humans then experimented with a series of modes of production, from the slave, to the feudal, to the capitalist mode, always seeking the solution and not finding it. Finally there came a true prophet with a message of salvation, Karl Marx, who preached the truth of Science. He promised redemption but was not heeded, except by his close disciples who carried the truth forward. Eventually, however, the proletariat, the carriers of the true faith, will be converted by the religious elect, the leaders of the party, and join to create a more perfect world. A final, terrible revolution will wipe out capitalism, alienation, exploitation, and inequality. After that, history will end because there will be perfection on earth, and the true believers will have been saved.

Nossa família


The chimpanzee and the human share about 99.5 per cent of their evolutionary history, yet most human thinkers regard the chimp as a malformed, irrelevant oddity while seeing themselves as stepping-stones to the Almighty. To an evolutionist this cannot be so. There exists no objective basis on which to elevate one species above another. Chimp and human, lizard and fungus, we have all evolved over some three billion years by a process known as natural selection. Within each species some individuals leave more surviving offspring than others, so that the inheritable traits (genes) of the reproductively successful become more numerous in the next generation. This is natural selection: the non-random differential reproduction of genes. Natural selection has built us, and it is natural selection we must understand if we are to comprehend our own identities.

A Morena e eu, tão próximos mas tão longe nesse Cosmos



Eu estava vendo o único verbete sobre o tudo da maior enciclopédia conhecida nesse tudo: o Universo. Não é o Guia do Mochileiro das Galáxias, algo próximo mas não tão engraçado, a Wikipedia.

Lendo em inglês, que é a lingua franca atual.

Diz o verbete:

The universe is commonly defined as the totality of existence,[1][2][3][4] including planetsstarsgalaxies, the contents of intergalactic space, and all matter and energy.[5][6]

Fui ver as referências e gostei dessa:

2. ^ "Universe"Encyclopedia Britannica, "the whole cosmic system of matter and energy of which Earth, and therefore the human race, is a part"

Carl Sagan usou um sinônimo: "O Cosmos é tudo o que existe, existiu ou existirá. A mais insignificante contenmplação do cosmos emociona-nos – provoca-nos um arrepio, embarga-nos a voz, causa-nos a sensação suave de uma recordação distante."

Mas tudo isso fica gravemente desfalcado de sentido se meu amor pela Priscilla Casagrande não for correspondido. Até o ateu mais materialista irá concordar que não haveria pecado maior caso isso ocorresse.



P.S. Parabéns pela condecoração, Morena!

Ternura



Eu te peço perdão por te amar de repente
Embora o meu amor
seja uma velha canção nos teus ouvidos
Das horas que passei à sombra dos teus gestos
Bebendo em tua boca o perfume dos sorrisos
Das noites que vivi acalentando
Pela graça indizível
dos teus passos eternamente fugindo
Trago a doçura
dos que aceitam melancolicamente.
E posso te dizer
que o grande afeto que te deixo
Não traz o exaspero das lágrimas
nem a fascinação das promessas
Nem as misteriosas palavras
dos véus da alma...
É um sossego, uma unção,
um transbordamento de carícias
E só te pede que te repouses quieta,
muito quieta
E deixes que as mãos cálidas da noite
encontrem sem fatalidade
o olhar estático da aurora.

Encontro em Bagdá


There was a merchant in Baghdad who sent his servant to market to buy provisions and in a little while the servant came back, white and trembling, and said, Master, just now when I was in the market-place I was jostled by a woman in the crowd and when I turned I saw it was Death that jostled me. She looked at me and made a threatening gesture; now, lend me your horse, and I will ride away from this city and avoid my fate. I will go to Samarra and there Death will not find me. The merchant lent him his horse, and the servant mounted it, and he dug his spurs in its flanks and as fast as the horse could gallop he went. Then the merchant went down to the market-place and he saw me standing in the crowd, and he came to me and said, why did you make a threatening gesture to my servant when you saw him this morning? That was not a threatening gesture, I said, it was only a start of surprise. I was astonished to see him in Baghdad, for I had an appointment with him tonight in Samarra.

A Era da Empatia



Na tentativa de revelar os elementos mais básicos da empatia, optei por incluir explicitamente os não humanos na discussão. Nem todos os cientistas concordam com isso. Alguns deles fazem como aqueles macacos que tapam a boca e os ouvidos com as mãos assim que alguém menciona a expressão “estados internos” em relação aos animais não humanos. Não há problema algum em descrever o comportamento humano com termos emocionais, acredita-se, mas esse é um hábito que devemos abolir quando se trata dos animais. Muitos de nós consideram isso quase impossível, pela simples razão de que os humanos tendem a “mentalizar” automaticamente. A mentalização oferece um atalho em relação ao comportamento à nossa volta. Em vez de fazermos observações parciais sobre o modo como nosso patrão reage quando chegamos atrasados (ele franze as sobrancelhas, fica com o rosto vermelho, bate na mesa, e assim por diante), integramos todas essas informações numa única avaliação (ele está enfurecido). Tendemos a acomodar nossas observações sobre o comportamento das pessoas aos objetivos, desejos, necessidades e emoções que atribuímos a elas. Isso funciona adequadamente com o nosso patrão (embora pouco melhore a situação), e aplica-se igualmente bem a um cachorro que vem pulando em nossa direção, balançando o rabo, em contraste com outro que rosna para nós com a cabeça  baixa e o pelo eriçado. Dizemos que o primeiro está “feliz”, e o segundo, “bravo”, embora muitos cientistas ridicularizem o emprego desse léxico porque ele implica a atribuição de estados mentais. Eles preferem termos como “brincalhão” ou “agressivo”. Os pobres dos cachorros fazem de tudo para expressar seus sentimentos, enquanto a ciência se enreda em complicados volteios lingüísticos para evitar mencioná-los.
Obviamente, não estou de acordo com essa cautela. Para o darwinista, não há nada mais lógico do que pressupor a continuidade emocional entre o homem e os outros animais. No final das contas, eu acredito que a relutância em falar sobre as emoções dos animais tem menos a ver com a ciência do que com a religião. Isso vale especialmente para aquelas religiões que nasceram isoladas dos animais que se parecem conosco. Com macacos e grandes primatas à sua volta por todo o lado, nenhuma população das florestas tropicais jamais produziu uma religião que situasse os humanos fora da natureza. Da mesma forma, os países do Oriente – como a Índia, a China e o Japão, cercados de primatas nativos – criaram religiões que não estabeleceram fronteiras rígidas entre os humanos e os outros animais. A reencarnação pode ocorrer de muitas formas diferentes: um homem pode retornar como um peixe e um peixe pode transformar-se num Deus. Deuses macacos, como Hanuman, são comuns. Somente as religiões judeo-cristãs colocam o homem num pedestal, afirmando ser ele a única espécie dotada de alma. Não é difícil entender como os nômades do deserto podem ter chegado a ver as coisas dessa maneira. Na ausência de animais que pudessem servir-lhe de espelho, a idéia da exclusividade da espécie humana ocorreu naturalmente a eles, que viram-se como seres criados à imagem de Deus e como a única forma de vida inteligente do planeta. Ainda hoje, estamos tão convencidos disso que procuramos outras formas de vida inteligente apontando nossos poderosos telescópios para galáxias distantes.
A reação dos ocidentais quando finalmente tiveram contato com os animais capazes de colocar essas crenças em cheque é extremamente reveladora. Quando espécimes vivos de grandes primatas foram exibidos pela primeira vez, as pessoas mal podiam acreditar no que viam. Em 1835, um chimpanzé macho chegou ao zoológico de Londres vestindo um uniforme de marinheiro.  Depois dele foi a vez de uma fêmea de orangotango, apresentada com um vestido.  Ao ver a exposição, a rainha Vitória afirmou que os primatas eram “assustadores, [...] dolorosa e desagradavelmente humanos”. Tratava-se de um sentimento generalizado na época, e ainda hoje eu às vezes encontro pessoas que consideram os grandes primatas “repulsivos”. Por que razão elas reagiriam assim a menos que esses animais lhes dissessem algo a respeito de si mesmos que elas não desejassem ouvir? Quando Charles Darwin, em sua juventude, estudou os mesmos primatas no zoológico de Londres, ele chegou à mesma conclusão que a rainha, mas sem a repugnância experimentada por ela. Darwin considerou que toda pessoa convencida da superioridade humana deveria dar uma espiada nesses primatas.

Impotence therefore faces both those who believe in what amounts to a pure, stateless, market capitalism, a sort of international bourgeois anarchism, and those who believe in a planned socialism uncontaminated by private profit-seeking. Both are bankrupt. The future, like the present and the past, belongs to mixed economies in which public and private are braided together in one way or another. But how?

Humanismo



The word 'humanism' has had , and continues to have, a variety of meanings. At its broadest, 'humanism' means little more than a system of thought in which human values, interests, and dignity are considered particularly important. Understood in this way, perhaps almost every one qualifies as a humanist (including those of us who are religious).

However, those who organize under the banner of 'humanism' today, especially in the UK, usually mean something rather more focused. They embrace a particular kind of worldview tha by no means every one accept. That worldview is the focus of this book.

So what distinguishes the humanist outlook? It is difficult to be very precise. The boundaries of the concept are elastic. But I think most humanists would probably agree on something like the following minimal, seven-point characterization (in no particular order):

First, humanists believe science, and reason more generally, are invaluable tools we can and should apply to all areas of life. No beliefs should be considered off-limits and protected from rational scrutiny.

Second, humanists are either atheists or at least agnostics. They are sceptical about the claim that there exists a god or gods. They are also sceptical about angels, demons, and other such supernatural beings.

Third, humanists believe that this life is the only life we have. We are not reincarnated. Nor is there any heaven or hell to which we go after we die. Notice that the humanist's sceptical position regarding both gods and an afterlife is not a dogmatic 'faith position', but a consequence of their having subjected such beliefs to critical scrutiny and found them seriously wanting.

Fourth, humanism involves a commitment to the existence and importance of moral value. Humanists also believe our ethics should be strongly informed by study of what human beings are actually like, and of what  will help them flourishing in this world, rather then the next. Humanists reject such negative claims as that there cannot be moral value without God, and that we will not be, or are unlikely to be, good without God and religion to guide us. Humanists offer moral justifications and arguments rooted other than in religious authority and dogma.

Fifth, humanists emphasize our individual moral autonomy. It is our individual responsability to make our own moral judgements, rather than attempt to hand that responsability over to some external authority - such as a political leader or religion - that will make those judgements for us. Humanists favour developing forms of moral education that emphasize this responsability and that will equip us with the skills we will need to discharge properly.

Sixth, humanists believe our lives can have meaning without it being bestowed from above by God. They suppose that the lives of, say, Pablo Picasso, Marie Curie, Ernest Shackelton, and Albert Einstein were all rich, significant, and meaningful, whether there is a God or not.

Seventh, humanists are secularists, in the sense that they favour an open, democractic society in which the state takes a neutral position with respect to religion, protecting the freedom of individuals to follow and espouse, or reject and criticize, both religious and atheist beliefs. While humanists will obviously oppose any attempt to coerce people into embracing religious belief, they are no less opposed to coercing people into embracing atheism, as happened under certain totalitarian regimes.

Melhor ficção científica da história



6 - Ascent of Man

A new animal was abroad on the planet, spreading slowly out from the African heartland. It was still so rare that a hasty census might have overlooked it, among the teeming billions of creatures roving over land and sea. There was no evidence, as yet, that it would prosper or even survive: on this world where so many mightier beasts had passed away, its fate still wavered in the balance.

In the hundred thousand years since the crystals had descended upon Africa, the man-apes had invented nothing. But they had started to change, and had developed skills which no other animal possessed. Their bone clubs had increased their reach and multiplied their strength; they were no longer defenseless against the predators with whom they had to compete. The smaller carnivores they could drive away from their own kills; the larger ones they could at least discourage, and sometimes put to flight.

Their massive teeth were growing smaller, for they were no longer essential. The sharp-edged stones that could be used to dig out roots, or to cut and saw through tough flesh or fiber, had begun to replace them, with immeasurable consequences. No longer were the man-apes faced with starvation when their teeth became damaged or worn; even the crudest tools could add many years to their lives. And as their fangs diminished, the shape of their face started to alter; the snout receded, the massive jaw became more delicate, the mouth able to make more subtle sounds. Speech was still a million years away, but the first steps toward it had been taken.

And then the world began to change. In four great waves, with two hundred thousand years between their crests, the Ice Ages swept by, leaving their mark on all the globe. Outside the tropics, the glaciers slew those who had prematurely left theft ancestral home; and everywhere they winnowed out the creatures who could not adapt.

When the ice had passed, so had much of the planet's early life - including the man-apes. But, unlike so many others, they had left descendants; they had not merely become extinct - they had been transformed. The toolmakers had been remade by their own tools.

For in using clubs and flints, their hands had developed a dexterity found nowhere else in the animal kingdom, permitting them to make still better tools, which in turn had developed their limbs and brains yet further. It was an accelerating, cumulative process; and at its end was Man.

The first true men had tools and weapons only a little better than those of their ancestors a million years earlier, but they could use them with far greater skill.

And somewhere in the shadowy centuries that had gone before they had invented the most essential tool of all, though it could be neither seen nor touched. They had learned to speak, and so had won their first great victory over Time. Now the knowledge of one generation could be handed on to the next, so that each age could profit from those that had gone before.

Unlike the animals, who knew only the present, Man had acquired a past; and he was beginning to grope toward a future.

He was also learning to harness the forces of nature; with the taming of fire, he had laid the foundations of technology and left his animal origins far behind. Stone gave way to bronze, and then to iron. Hunting was succeeded by agriculture. The tribe grew into the village, the village into the town. Speech became eternal, thanks to certain marks on stone and clay and papyrus. Presently he invented philosophy, and religion. And he peopled the sky, not altogether inaccurately, with gods.

As his body became more and more defenseless, so his means of offense became steadily more frightful. With stone and bronze and iron and steel he had run the gamut of everything that could pierce and slash, and quite early in time he had learned how to strike down his victims from a distance. The spear, the bow, the gun, and finally the guided missile had given him weapons of infinite range and all but infinite power.

Without those weapons, often though he had used them against himself, Man would never have conquered his world. Into them he had put his heart and soul, and for ages they had served him well.

But now, as long as they existed, he was living on borrowed time.

Três livros sobre seleção natural


I well remember the thrill when I first learned the whole system of evolutionary logic as applied to biology from Dr. [William] Drury. It was similar to the feeling I had when I first fell in love with astronomy as a twelve-year old. Astronomy gave you inorganic creation and evolution over a 15-billion-year period of time. Evolutionary logic gave you the comparable story over 4 billion years and evolutionary logic applied to life. In both cases, I felt a sense of religious awe. Astronomy spoke of vastness of time and space while evolutionary biology did the same thing for living creatures. The living world was not created 6 thousand  years ago, in one blinding flash of creation, or in seven days, perhaps. Living creatures have been forming over a 4-billion-year period of time, with natural selection knitting together adaptive traits over time. Living creatures are expected to be organized functionally in exquisite and even counterintuitive forms. In no way did this perspective diminsh my sense of awe, nor did it argue, one way or another, for the existence of an omnipotent force to which personal attention was suggested.
- Robert Trivers ("Natural selection and social theory: selected papers of Robert Trivers", 2002, Oxford University Press, p. 57)


Sometime around my early thirties I stumbled upon evolutionary biology, particularly in the form of Richard Dawkins's books The Selfish Gene and then The Blind Watchmaker, and suddenly (on, I think the second reading of The Selfish Gene) it all fell into place. It was a concept of such stunning simplicity, but it gave rise, naturally, to all of the infinite and baffling complexity of life. The awe it inspired in me made the awe that people talk about in respect of religious experience seem, frankly, silly beside it. I'd take the awe of understanding over the awe of ignorance any day.
- Douglas Adams (Interview with American Atheits)


Successful biological research in this century has had three doctrinal bases: mechanism (as opposed to vitalism), natural selection (trial and error, as opposed to rational plan), and historicity. [Historicity] is the recognition of the role of historical contingency in determining properties of the Earth's biota. (...) Mechanism implies that every physico-chemical processes are at work in an organism. Every vital function is performed by material machinery that can in principle be understood from a physical and chemical examination. (...) The second basis of modern biology is the assumption that the Darwinian process of natural selection accounts for all aspects of the adaptation of an organism to a particular way of life in a particular environment.

Clipe do Dia nº 332


Isso soa como rock and roll aos meus ouvidos.

P.S. ...in this giant super CD format!

Soa como música aos meus ouvidos


A wise man proportions his belief to the evidence.
- David Hume

The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what's true.
- Carl Sagan

Probably all organic beings which have ever lived on this earth have descended from some one primordial life form. There is grandeur in this view of life that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being evolved.
- Charles Darwin

If you want to do evil, science provides the most powerful weapons to do evil; but equally, if you want to do good, science puts into your hands the most powerful tools to do so. The trick is to want the right things, then science will provide you with the most effective methods of achieving them.
- Richard Dawkins

It's a long way to the top (if you wanna rock 'n' roll)!
- Angus Young, Malcolm Young e Bon Scott
