"THEN was not non-existent nor existent: there was no realm of air, no sky beyond it.
     What covered in, and where? and what gave shelter? Was water there, unfathomed depth of water?
2. Death was not then, nor was there aught immortal: no sign was there, the day's and night's divider.
     That One Thing, breathless, breathed by its own nature: apart from it was nothing whatsoever.
3. Darkness there was: at first concealed in darkness this All was indiscriminate chaos.
     All that existed then was void and formless: by the great power of Warmth was born that Unit.
4. Thereafter rose Desire in the beginning, Desire, the primal seed and germ of Spirit.
     Sages who searched with their heart's thought discovered the existent's kinship in the non-existent.
5. Transversely was their severing line extended: what was above it then, and what below it?
     There were begetters, there were mighty forces, free action here and energy up yonder
6. Who verily knows and who can here declare it, whence it was born and whence comes this creation?
     The Gods are later than this world's production. Who knows then whence it first came into being?
7. He, the first origin of this creation, whether he formed it all or did not form it,
     Whose eye controls this world in highest heaven, he verily knows it, or perhaps he knows not."

Rig Veda Hino 129

Porque é que não conseguimos imaginar a morte

22.10.08
"...people in every culture believe in an afterlife of some kind or, at the very least, are unsure about what happens to the mind at death. My psychological research has led me to believe that these irrational beliefs, rather than resulting from religion or serving to protect us from the terror of inexistence, are an inevitable by-product of self-consciousness. Because we have never experienced a lack of consciousness, we cannot imagine what it will feel like to be dead. In fact, it won’t feel like anything—and therein lies the problem."

 

 


Quando tinha 16 anos tive um episódio convulsivo que, para todos os efeitos de consciência, desligou o meu cerebro. Lembro-me que, ao acordar, a maior sensação de horror resultava de não haver nenhuma memória do episódio.

Não estou a falar de não nos lembramos de um sonho ou de uma noite de copos, em que apesar de tudo ainda retemos a sensação vaga de tempo passado.

Estou a falar de Nada.

Foi, e é, a experiência mais assustadora que tive até agora. O que a torna tão aterradora é ter a certeza que deve ser muito parecida com a unica experiência que, tenho a certeza,  tem o potencial de me assustar ainda mais.

Muito giro.

Deixo-vos com a introdução mas, garanto-vos, o artigo é muito menos seco e muito mais interessante do que esta faz parecer.

 

Complicity and the Brain:
Dynamics in Attractor Space

 

 This paper is structured in five parts: Parts 1 and 2 introduce a class of dynamic systems called SONkANNs - self-organizing networks (k times iterated) of attractor neural networks. The usefulness of these systems is derived in two different ways:
Part 1 analyzes the brain as a dynamic system and searches for the simplest way to capture the essence of the workings of the brain in a toy realm.
Part 2 searches for the simplest system that can exhibit complicity or superemergence in a computer.
We consider it significant that these two arguments, based on neuroscience and dynamic systems theory, independently lead to the same system architecture. The class of systems we single out for further investigation are networks of Hopfield nets with the following properties:
The basic nets are configured for 2D-symbol recognition.
The network of Hopfield nets is governed by a regulatory network that can implement learning and shift attentional focus.
The network of networks is connected to an outside world through sensory-input/action-output channels.
We call such networks SOHNs (Self-Organizing Hopfield Networks).
Part 3 consists of a technical analysis of SOHNs, and part 4 concentrates on two interesting properties they have:
Semantics: Based on the existential connection to a valid outside world, and propagated through similarities between the symbol sets of neighboring Hopfield nets, the SOHNs can develop semantic content.
Brainwaves: The workings of the regulatory network can give rise to brainwaves which in suitable semantic networks can perform emergent information processing on a higher organizational level.
In Part 5 we suggest a method to investigate the space of SOHNs for outstanding cases of brainwave processing in semantic networks that can be considered cases of supermergence or consciousness. Our solution is to use the SOHNs as brains for actors in a virtual world that ``users'' can interact with as a computer game. If users are given an easy way to design/modify/train SOHNs, which they can then use to compete with their peers, we expect that a lot of ingenuity will be applied to find the SOHNs that act in the most intelligent manner. If the space of SOHNs allows for consciousness to emerge, we expect that this approach will eventually find systems that actually do so.
