  • An overview of wagers for reducing future suffering

    «Pascal’s wager is a famous argument for why one should believe in God. If God exists, then eternal life in heaven or hell is at stake, but if God doesn’t exist, one’s belief does not matter much – so one should wager on the former. (The validity of this argument has been discussed at length.)

    More generally, whenever we consider two hypotheses H1 and H2 about the world, the stakes may be higher in one of the two cases – say, if H1 is true. This is a reason to act as if H1 is true, even if it is not most likely. For instance, the precautionary principle emphasises caution towards potentially harmful innovations (e.g. a new medicine) as long as we have substantial uncertainty.

    In this post, I will consider wagers that are relevant to effective altruism – that is, hypotheses that would allow us to have a particularly large impact. I’m most interested in reducing future suffering, but many of these wagers also apply to other goals.»
  • Richard Dawkins about suffering in nature

    «The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute it takes me to compose this sentence, thousands of animals are being eaten alive; others are running for their lives, whimpering with fear; others are being slowly devoured from within by rasping parasites; thousands of all kinds are dying of starvation, thirst and disease.»

  • What is the problem of consciousness?

    The problem of consciousness can be formulated as follows: how is it that, from a purely material basis (a brain or a centralized nervous system), consciousness emerges? This is what the problem of consciousness really boils down to. Answering this requires answering the question, what structures must be present in an organism and how would they function for consciousness to be possible? In other words, of all the different ways that the bodies of animals are arranged, which ones contain structures and arrangements that give rise to consciousness? There is no reason to suppose that only a human-like central nervous system will give rise to consciousness, and a great deal of evidence that very different types of animals are conscious. An example is bird brains, which have many structural similarities to mammalian brains, but different arrangements of neurons. Yet their brain circuits seem to be wired in a different way that creates a similar effect in terms of consciousness and cognition. An octopus is an invertebrate with a very different type of nervous system. But an octopus exhibits behavior and responds to her environment like a conscious being.

  • Discussion on the concept of sentience

    drugmonkey said:

    You may have noticed a rash of posts around the ScienceBlogs decrying the ARA terrorist extremists who have vowed, again, to target the children of a UCLA neuroscientist. Dario Ringach famously gave up his nonhuman primate research in 2006 because of threats against his family. His participation in last week’s dialog held at the UCLA campus apparently induced the extremist attention seekers, angry at having the momentum and PR shift to their slightly more rational co-travelers, to renew their threats. This is utterly despicable. Utterly.

    This would be a great time for people who purport to be non-extremist animal rights advocates or sympathizers to do some deep soul searching. Soul searching that does not just easily write off the terrorists as a crazy fringe but asks penetrating questions about the nature of their own beliefs.

    I cannot help you with this difficult work but I noticed something a little odd and new to me popping up in comment threads following the posts linked above. It has to do with the concept of sentience.

    Wandering over to the Wikipedia entry I find a rather interesting set of observations.

    Sentience is the ability to feel or perceive subjectively. The term is used in philosophy (particularly in the philosophy of animal ethics and in eastern philosophy) as well as in science fiction and (occasionally) in the study of artificial intelligence. In each of these fields the term is used slightly differently.

    In eastern philosophy, sentience is a metaphysical quality of all things that requires our respect and care. In science fiction, sentience is “personhood”: the essential quality that separates humankind from machines or animals. Sentience is used in the study of consciousness to describe the ability to have sensations or experiences, known to some Western academic philosophers as “qualia”.

    Some advocates of animal rights argue that many animals are sentient in that they can feel pleasure and pain, and that this entails being entitled to some moral or legal rights.

    Well this certainly explains my confusion. To me, “sentience” has always been the science fiction concept. I suspect quite strongly that for most people, this is the connotation of the term.

    Interesting, is it not, that animal rights people would co-opt this term to mean “can feel pleasure or pain”? Why create this new use for the term, particularly when it has such strong associations with the full-human capacity, different from animals and machines science-fiction type of definition?

    Just another dishonest ploy to sway people to their way of thinking on something other than the merits. Of course they know what they are doing. Of course they know that they are creating this blurring of definitions in the minds of the undecided public. And of course they are hoping to lure everyone into using their terminology so that when people who are in favor of animal research say, well of course animals can feel pain, the ARA nut can claim that such people are admitting to sentience.

    When of course they are doing no such thing.

    Challenge anyone who uses this “sentience” gambit, eh? Get them to specify exactly what they mean. And ask what they are trying to pull with this redefinition nonsense.

  • Consciousness and self-consciousness

    Consciousness is being aware. Self-consciousness is being aware of oneself. Being conscious, rather than self-conscious, is the key concept in ethics.

    Consciousness can be defined as the state of having experiences. Conscious states, or mental states, are situations in which one is having any kind of experience, be it a sensorial experience, a thought, an emotion or whatever.

    Self-consciousness, a particular form of consciousness, is a broad term that is used to mean different forms of awareness regarding oneself and one’s experiences. The way we understand the concept of the self depends on which meaning of self-consciousness we use.

  • How does the world view of a believer in physicalism differ from one of idealism?

    Physicalism is the view that no “element of reality” (Einstein) is missing from the mathematical equations of physics – more strictly, tomorrow’s physics beyond the Standard Model plus GR.
    Idealism is the view that reality is experiential.
    Most physicalists aren’t idealists, and most idealists aren’t physicalists, but a small minority of researchers are both idealists and physicalists.

    The intrinsic nature of quantum states is disputed. But if quantum mechanics is complete, and if the equations of physics describe fields of sentience rather than insentience, then physicalistic idealism is true. If so, there is no Hard Problem of consciousness as normally framed. Fields of insentience are destined to go the way of luminiferous aether. Formally, physical reality is described by the universal wavefunction. By contrast, consciousness is often said to be ill-defined. Yet if physicalistic idealism is true, then we already possess the mathematical apparatus of a theory of consciousness. All that’s hard is to “read off” the textures of experience from the solutions to the equations. The conjecture that relativistic QFT describes fields of sentience rather than insentience still leaves the mystery of why anything exists for the equations to describe: one big mystery rather than two. Yet even here, the superposition principle of QM hints at an answer.

  • Conceptualizing suffering and pain

    Pain can be described in neurological terms but cognitive awareness, interpretation, behavioral dispositions, as well as cultural and educational factors have a decisive influence on pain perception. Suffering is proposed to be defined as an unpleasant or even anguishing experience, severely affecting a person at a psychophysical and existential level. Pain and suffering are considered unpleasant. However, the provided definitions neither include the idea that pain and suffering can attack and even destroy the self nor the idea that they can constructively expand the self; both perspectives can be equally useful for managing pain and suffering, but they are not defining features of the same. Including the existential dimension in the definition of suffering highlights the relevance of suffering in life and its effect on one’s own attachment to the world (including personal management, or the cultural and social influences which shape it). An understanding of pain and suffering life experiences is proposed, meaning that they are considered aspects of a person’s life, and the self is the ever-changing sum of these (and other) experiences.

  • The emotional need of a «scenario completion» and the difference between a cook and a chef

    The need of a «scenario completion»

    «Fascinating concept that I came across in military/police psychology dealing with the unique challenges people face in situations of extreme stress/danger: scenario completion. Take the normal pattern completion that people do and put fear blinders on them so they only perceive one possible outcome and they mechanically go through the motions *even when the outcome is terrible* and there were obvious alternatives. This leads to things like officers shooting *after* a suspect has already surrendered, having overly focused on the possibility of needing to shoot them. It seems similar to target fixation where people under duress will steer a vehicle directly into an obstacle that they are clearly perceiving (looking directly at) and can’t seem to tear their gaze away from. Or like a self fulfilling prophecy where the details of the imagined bad scenario are so overwhelming, with so little mental space for anything else that the person behaves in accordance with that mental picture even though it is clearly the mental picture of the *un*desired outcome.

    I often try to share the related concept of stress induced myopia. I think that even people not in life or death situations can get shades of this sort of blindness to alternatives. It is unsurprising when people make sleep a priority and take internet/screen fasts that they suddenly see that the things they were regarding as obviously necessary are optional. In discussion of trauma with people this often seems to be an element of relationships sadly enough. They perceive no alternative and so they resign themselves to slogging it out for a lifetime with a person they are very unexcited about. This is horrific for both people involved.»

    …and the opposite: how is Elon’s Software?

    The difference between the way Elon thinks and the way most people think is kind of like the difference between a cook and a chef. […]

    Musk calls this “reasoning from first principles.” I’ll let him explain:

    I think generally people’s thinking process is too bound by convention or analogy to prior experiences. It’s rare that people try to think of something on a first principles basis. They’ll say, “We’ll do that because it’s always been done that way.” Or they’ll not do it because “Well, nobody’s ever done that, so it must not be good.” But that’s just a ridiculous way to think. You have to build up the reasoning from the ground up—“from the first principles” is the phrase that’s used in physics. You look at the fundamentals and construct your reasoning from that, and then you see if you have a conclusion that works or doesn’t work, and it may or may not be different from what people have done in the past.5

    My favorite all-time quote might be Steve Jobs saying this:

    When you grow up, you tend to get told the world is the way it is and your life is just to live your life inside the world. Try not to bash into the walls too much. Try to have a nice family life, have fun, save a little money. That’s a very limited life. Life can be much broader once you discover one simple fact. And that is: Everything around you that you call life was made up by people that were no smarter than you. And you can change it, you can influence it, you can build your own things that other people can use. Once you learn that, you’ll never be the same again.

    […]

    Most people would have stuck with the Stanford program—because they had already told everyone about it and it would be weird to quit, because it was Stanford, because it was a more normal path, because it was safer, because the internet might be a fad, because what if he were 35 one day and was a failure with no money because he couldn’t get a good job without the right degree.

    Musk quit the program after two days. The big macro arrow of his software came down on the right, saw that what he was embarking on wasn’t in the Goal Pool anymore, and he trusted his software—so he made a macro change.

    He started Zip2 with his brother, an early cross between the concepts of the Yellow Pages and Google Maps. Four years later, they sold the company and Elon walked away with $22 million.

    As a dotcom millionaire, the conventional wisdom was to settle down as a lifelong rich guy and either invest in other companies or start something new with other people’s money. But Musk’s goal formation center had other ideas. His Want box was bursting with ambitious startup ideas that he thought could have major impact on the world, and his Reality box, which now included $22 million, told him that he had a high chance of succeeding. Being leisurely on the sidelines was nowhere in his Want box and totally unnecessary according to his Reality box.

    So he used his newfound wealth to start X.com in 1999, with the vision to build a full-service online financial institution. The internet was still young and the concept of storing your money in an online bank was totally inconceivable to most people, and Musk was advised by many that it was a crazy plan. But again, Musk trusted his software. What he knew about the internet told him that this was inside the Reality box—because his reasoning told him that when it came to the internet, the Reality box had grown much bigger than people appreciated—and that was all he needed to know to move forward. In the top part of his software, as his strategy-action-results-adjustments loop spun, X.com’s service changed, the team changed, the mission changed, even the name changed. By the time eBay bought it in 2002, the company was called PayPal and it was a money transfer service. Musk made $180 million.

    Bonus tip: about Tim Urban’s and Elon Musk’s idea of consciousness:

    «One topic I disagreed with him on is the nature of consciousness. I think of consciousness as a smooth spectrum. To me, what we experience as consciousness is just what it feels like to be human-level intelligent. We’re smarter, and “more conscious” than an ape, who is more conscious than a chicken, etc. And an alien much smarter than us would be to us as we are to an ape (or an ant) in every way. We talked about this, and Musk seemed convinced that human-level consciousness is a black-and-white thing—that it’s like a switch that flips on at some point in the evolutionary process and that no other animals share. He doesn’t buy the “ants : humans :: humans : [a much smarter extra-terrestrial]” thing, believing that humans are weak computers and that something smarter than humans would just be a stronger computer, not something so beyond us we couldn’t even fathom its existence.»

  • Ideology of Reproduction versus Non-Suffering and conservatism vs progressivism

    «While every sensitive being fundamentally wishes to avoid suffering and experience happiness, curiously, human societies have almost never made non-suffering and happiness their founding values. Why? The ideology of reproduction has existed for 100,000 years, while the belief that the spirit survives the death of the body appears. We must reproduce so that a progeny can take care of our spirit after our death. The supreme value is reproduction, and therefore life. The strength of this discourse is such that the ideology of reproduction, which has forged most of our laws, has finally imposed itself through unconscious internalization, even today. To come out of it, to deconstruct this ideology is a condition for the flourishing of the values of non-suffering and happiness that appeared much later, only 2500 years ago, in India and Greece.»

    From the Jean-Christophe Lurenbaum’s book: «Is “Being Born” in the Best Interest of the Child? – Ideology of Reproduction versus Non-Suffering»

    «A key to understanding what is behind conservatism and progressivism is that the former is pro-life or for «reproduction» in the broad sense, whilst the latter is for suffering-alleviation» — Robert Daoust
