In his article, Freeman derides the first organism that hoarded its + genes behind a protective membrane as “evil,” just like the nemesis of the + open-software movement, Bill Gates. + + Once organisms became encapsulated, they isolated themselves into distinct + species, trading genes only with others of their kind.

This term is usually + used more narrowly to describe a philosophy of mind, but I’ll extend it to + include something like a culture. A first pass at a summary of the underlying + philosophy is that the world can be understood as a computational process, with + people as subprocesses. + + [...] + + In a scientific role, I don’t recoil from the idea that the brain is a kind of + computer, but there is more than one way to use computation as a source of + models for human beings. I’ll discuss three common flavors of computationalism + and then describe a fourth flavor, the one that I prefer. Each flavor can be + distinguished by a different idea about what would be needed to make software + as we generally know it become more like a person. + + One flavor is based on the idea that a sufficiently voluminous computation will + take on the qualities we associate with people—such as, perhaps, consciousness. + One might claim Moore’s law is inexorably leading to superbrains, superbeings, + and, perhaps, ultimately, some kind of global or even cosmic consciousness. If + this language sounds extreme, be aware that this is the sort of rhetoric you + can find in the world of Singularity enthusiasts and extropians. + + [...] + + A second flavor of computationalism holds that a computer program with specific + design features—usually related to self-representation and circular + references—is similar to a person. Some of the figures associated with this + approach are Daniel Dennett and Douglas Hofstadter, though each has his own + ideas about what the special features should be. + + Hofstadter suggests that software that includes a “strange loop” bears a + resemblance to consciousness. In a strange loop, things are nested within + things in such a way that an inner thing is the same as an outer thing. + + [...] + + A third flavor of computationalism is found in web 2.0 circles. In this case, + any information structure that can be perceived by some real human to also be a + person is a person. This idea is essentially a revival of the Turing test. If + you can perceive the hive mind to be recommending music to you, for instance, + then the hive is effectively a person. + + [...] + + The approach to thinking about people computationally that I prefer, on those + occasions when such thinking seems appropriate to me, is what I’ll call + “realism.” The idea is that humans, considered as information systems, weren’t + designed yesterday, and are not the abstract playthings of some higher being, + such as a web 2.0 programmer in the sky or a cosmic Spore player. Instead, I + believe humans are the result of billions of years of implicit, evolutionary + study in the school of hard knocks. The cybernetic structure of a person has + been refined by a very large, very long, and very deep encounter with physical + reality. + +### From Images to Odors + + For twenty years or so I gave a lecture introducing the fundamentals of virtual + reality. I’d review the basics of vision and hearing as well as of touch and + taste. At the end, the questions would begin, and one of the first ones was + usually about smell: Will we have smells in virtual reality machines anytime + soon? + + Maybe, but probably just a few. Odors are fundamentally different from images + or sounds. The latter can be broken down into primary components that are + relatively straightforward for computers—and the brain—to process. The visible + colors are merely words for different wavelengths of light. Every sound wave is + actually composed of numerous sine waves, each of which can be easily described + mathematically. + + [...] + + Odors are completely different, as is the brain’s method of sensing them. Deep + in the nasal passage, shrouded by a mucous membrane, sits a patch of tissue—the + olfactory epithelium—studded with neurons that detect chemicals. Each of these + neurons has cup-shaped proteins called olfactory receptors. When a particular + molecule happens to fall into a matching receptor, a neural signal is triggered + that is transmitted to the brain as an odor. A molecule too large to fit into + one of the receptors has no odor. The number of distinct odors is limited only + by the number of olfactory receptors capable of interacting with them. Linda + Buck of the Fred Hutchinson Cancer Research Center and Richard Axel of Columbia + University, winners of the 2004 Nobel Prize in Physiology or Medicine, have + found that the human nose contains about one thousand different types of + olfactory neurons, each type able to detect a particular set of chemicals. + + This adds up to a profound difference in the underlying structure of the + senses—a difference that gives rise to compelling questions about the way we + think, and perhaps even about the origins of language. There is no way to + interpolate between two smell molecules. True, odors can be mixed together to + form millions of scents. But the world’s smells can’t be broken down into just + a few numbers on a gradient; there is no “smell pixel.” Think of it this way: + colors and sounds can be measured with rulers, but odors must be looked up in a + dictionary. + + [...] + + To solve the problem of olfaction—that is, to make the complex world of smells + quickly identifiable—brains had to have evolved a specific type of neural + circuitry, Jim believes. That circuitry, he hypothesizes, formed the basis for + the cerebral cortex—the largest part of our brain, and perhaps the most + critical in shaping the way we think. For this reason, Jim has proposed that + the way we think is fundamentally based in the olfactory. + + [...] + + He often refers to the olfactory parts of the brain as the “Old Factory,” as + they are remarkably similar across species, which suggests that the structure + has ancient origins. + +## Editing Is Sexy; Creativity Is Natural + + These experiments in linguistic variety could also inspire a better + understanding of how language came about in the first place. One of Charles + Darwin’s most compelling evolutionary speculations was that music might have + preceded language. He was intrigued by the fact that many species use song for + sexual display and wondered if human vocalizations might have started out that + way too. It might follow, then, that vocalizations could have become varied and + complex only later, perhaps when song came to represent actions beyond mating + and such basics of survival. + + [...] + + Terry offered an unconventional solution to the mystery of Bengalese finch + musicality. What if there are certain traits, including song style, that + naturally tend to become less constrained from generation to generation but are + normally held in check by selection pressures? If the pressures go away, + variation should increase rapidly. Terry suggested that the finches developed a + wider song variety not because it provided an advantage but merely because in + captivity it became possible. + + In the wild, songs probably had to be rigid in order for mates to find each + other. Birds born with a genetic predilection for musical innovation most + likely would have had trouble mating. Once finches experienced the luxury of + assured mating (provided they were visually attractive), their song variety + exploded. + + Brian Ritchie and Simon Kirby of the University of Edinburgh worked with Terry + to simulate bird evolution in a computer model, and the idea worked well, at + least in a virtual world. Here is yet another example of how science becomes + more like storytelling as engineering becomes able to represent some of the + machinery of formerly subjective human activities. + +## Metaphors + + One reason the metaphor of the sun fascinates me is that it bears on a conflict + that has been at the heart of information science since its inception: Can + meaning be described compactly and precisely, or is it something that can + emerge only in approximate form based on statistical associations between large + numbers of components? + + Mathematical expressions are compact and precise, and most early computer + scientists assumed that at least part of language ought to display those + qualities too. + +## Future Humors + + Unfortunately, we don’t have access at this time to a single philosophy that + makes sense for all purposes, and we might never find one. Treating people as + nothing other than parts of nature is an uninspired basis for designing + technologies that embody human aspirations. The inverse error is just as + misguided: it’s a mistake to treat nature as a person. That is the error that + yields confusions like intelligent design. + + [...] + + Those who enter into the theater of computationalism are given all the mental + solace that is usually associated with traditional religions. These include + consolations for metaphysical yearnings, in the form of the race to climb to + ever more “meta” or higher-level states of digital representation, and even a + colorful eschatology, in the form of the Singularity. And, indeed, through the + Singularity a hope of an afterlife is available to the most fervent believers. + +## My Brush with Bachelardian Neoteny in the Most Interesting Room in the World + + But actually, because of homuncular flexibility, any part of reality might just + as well be a part of your body if you happen to hook up the software elements + so that your brain can control it easily. Maybe if you wiggle your toes, the + clouds in the sky will wiggle too. Then the clouds would start to feel like + part of your body. All the items of experience become more fungible than in the + physical world. And this leads to the revelatory experience. + +## Final Words + + For me, the prospect of an entirely different notion of communication is more + thrilling than a construction like the Singularity. Any gadget, even a big one + like the Singularity, gets boring after a while. But a deepening of meaning is + the most intense potential kind of adventure available to us. diff --git a/research/panc.mdwn b/research/panc.mdwn index 0b85266..04b584e 100644 --- a/research/panc.mdwn +++ b/research/panc.mdwn @@ -33,6 +33,7 @@ * Livro do knuppi e do lorenzi * Instituto plantarum * [Como diferenciar serralha e dente-de-leão](http://www.matosdecomer.com.br/2016/08/como-diferenciar-serralha-e-dente-de.html). +* [Cartilha Guia Prático de PANC Plantas Alimenticias Nao Convencionais](http://institutokairos.net/wp content/uploads/2017/08/Cartilha Guia Pr%C3%A1tico de PANC Plantas Alimenticias Nao Convencionais.pdf). ## Pesquisas futuras: diff --git a/research/python.mdwn b/research/python.mdwn index 72098c2..3a62cad 100644 --- a/research/python.mdwn +++ b/research/python.mdwn @@ -44,6 +44,36 @@ Python encourages polymorphism: floating points sometimes can, in different ways—by using rational representation and by limiting precision +### Types + + More formally, there are three major type (and operation) categories in Python + that have this generic nature: + + Numbers (integer, floating-point, decimal, fraction, others) + Support addition, multiplication, etc. + Sequences (strings, lists, tuples) + Support indexing, slicing, concatenation, etc. + Mappings (dictionaries) + Support indexing by key, etc. + + [...] + + The major core types in Python break down as follows: + + Immutables (numbers, strings, tuples, frozensets) + None of the object types in the immutable category support in-place changes, + though we can always run expressions to make new objects and assign their + results to variables as needed. + + Mutables (lists, dictionaries, sets, bytearray) + Conversely, the mutable types can always be changed in place with operations + that do not create new objects.
