In memoriam of Raymond Smullyan: An unfortunate dualist

Mind-body Dualists believe there are two different realms that define us. One is the physical realm, well studied and understood by the laws of physics, while the other one is the non-physical realm, where our selves exist. Our essence, our soul, if you want, exists in this non-physical realm, and it interacts and controls our physical body through some as yet unexplained mechanism. Most religions are based on a dualist theory, including Christianity, Islam, and Hinduism.

On the other side of the discussion are Monists, who do not believe in the existence of dual realities.  The term monism is used to designate the position that everything is either mental (idealism) or that everything is physical (materialism).

Raymond Smullyan, deceased two days ago (February 10th, 2017),


had a clear view on dualism, which he makes clear in this history, published in his book This book needs no title.

An Unfortunate Dualist

Once upon a time there was a dualist. He believed that mind and matter are separate substances. Just how they interacted he did not pretend to know-this was one of the “mysteries” of life. But he was sure they were quite separate substances. This dualist, unfortunately, led an unbearably painful life-not because of his philosophical beliefs, but for quite different reasons. And he had excellent empirical evidence that no respite was in sight for the rest of his life. He longed for nothing more than to die. But he was deterred from suicide by such reasons as: (1) he did not want to hurt other people by his death; (2) he was afraid suicide might be morally wrong; (3) he was afraid there might be an afterlife, and he did not want to risk the possibility of eternal punishment. So our poor dualist was quite desperate.

Then came the discovery of the miracle drug! Its effect on the taker was to annihilate the soul or mind entirely but to leave the body functioning exactly as before. Absolutely no observable change came over the taker; the body continued to act just as if it still had a soul. Not the closest friend or observer could possibly know that the taker had taken the drug, unless the taker informed him. Do you believe that such a drug is impossible in principle? Assuming you believe it possible, would you take it? Would you regard it as immoral? Is it tantamount to suicide? Is there anything in Scriptures forbidding the use of such a drug? Surely, the body of the taker can still fulfill all its responsibilities on earth. Another question: Suppose your spouse took such a drug, and you knew it. You would know that she (or he) no longer had a soul but acted just as if she did have one. Would you love your mate any less?

To return to the story, our dualist was, of course, delighted! Now he could annihilate himself (his soul, that is) in a way not subject to any of the foregoing objections. And so, for the first time in years, he went to bed with a light heart, saying: “Tomorrow morning I will go down to the drugstore and get the drug. My days of suffering are over at last!” With these thoughts, he fell peacefully asleep.

Now at this point a curious thing happened. A friend of the dualist who knew about this drug, and who knew of the sufferings of the dualist, decided to put him out of his misery. So in the middle of the night, while the dualist was fast asleep, the friend quietly stole into the house and injected the drug into his veins. The next morning the body of the dualist awoke-without any soul indeed-and the first thing it did was to go to the drugstore to get the drug. He took it home and, before taking it, said, “Now I shall be released.” So he took it and then waited the time interval in which it was supposed to work. At the end of the interval he angrily exclaimed: “Damn it, this stuff hasn’t helped at all! I still obviously have a soul and am suffering as much as ever!”

Doesn’t all this suggest that perhaps there might be something just a little wrong with dualism?

India considers the adoption of Universal Basic Income

A recent article published in The Economist reports that India is considering the adoption of a Universal Basic Income (UBI) scheme to replace a myriad of existing welfare systems.

Unlike the discussions that are taking place in other countries, this discussion about Universal Basic Income is not motivated by advances in technology and the fear of massive unemployment. The main aim of such a measure would be to replace many existing welfare mechanisms that are expensive, ineffective, and misused.

The scheme would provide every single citizen with a guaranteed basic income of 9 dollars a month ( hardly a vast sum ) and would cost between 6 and 7% of GDP. The 950 existing welfare schemes cost about 5% of GDP. Such a large scale experiment would, at least, contribute to make clear the advantages and disadvantages of UBI as a way to make sure every human being has a minimum wage, independent of any other considerations or the existence of jobs.

Will the fourth industrial revolution destroy or create jobs?

The impact of the fourth industrial revolution on jobs has been much discussed.

On one side, there are the traditional economists, who argue that technological advances have always created more and better jobs than the ones they destroyed. On the other side, the people that believe that with the arrival of artificial intelligence and robotics, there will simply not exist enough jobs that cannot be done by machines.

So, in this post, I try to present a balanced analysis on the subject, as deeply as allowed by the space and time available.

Many studies have addressed the question of which jobs are more likely to be destroyed by automation.  This study, by McKinsey, provides a very comprehensive analysis.


Recently, The Economist also published a fairly balanced analysis of the topic, already posted in this blog. In this analysis, The Economist makes a reference to a number of studies on the jobs that are at high risk but, in the end, it sides with the opinion that enough jobs will be created to replace the ones technology will destroy.

A number of books and articles have been written on the topic, including “Raising the Floor“, “The Wealth of Humans: Work, Power, and Status in the Twenty-first Century“, “The Second Machine Age“, and “No More Work“, some of them already reviewed in this blog.

In most cases, the authors of these books advocate the need for significant changes in the way society is organized, and on the types of social contracts that need to be drawn. Guaranteeing every one a universal basic income is a proposal that has become very popular, as a way to address the question of how humanity will live in a time when there are much less jobs to go around.

Further evidence that some deep change is in the cards is provided by data that shows that, with the begining of the XXI century, income is being moved away from jobs (and workers) towards capital (and large companies):


On the other side of the debate, there are many people who believe that humans will always be able to adapt and add value to society, regardless of what machines can or cannot do. David Autor, in his TED talk, makes a compelling point that many times before it was argued that “this time is different” and that it never was.

Other articles, including this one in the Washington Post, argue that the fears are overblown. The robots will not be coming in large numbers, to replace humans. Not in the near future, anyway.

Other economists, such as  Richard Freeman, in an article published in Harvard Magazine agree and also believe that the fears are unwarranted: “We should worry less about the potential displacement of human labor by robots than about how to share fairly across society the prosperity that the robots produce.

His point is that the problem is not so much on the lack of jobs, but on the depression of wages. Jobs may still exist, but will not be well paid, and the existing imbalances in income distribution will only become worst.

Maybe, in the end, this opinion represents a balanced synthesis of the two competing views: jobs will still exist, for anyone who wants to take them, but there will be competition (from robots and intelligent agents) for them, pushing down the wages.

European Parliament committee approves proposal to give robots legal status and responsibilities

The committee on legal affairs of the European Parliament has drafted and approved a report that addresses many of the legal, social and financial consequences of the development of robots and artificial intelligence (AI).

The draft report addresses a large number of issues related with the advances of robotics, AI and related technologies, and proposes a number of european regulations to govern the utilization of robots and other advanced AI agents.

The report was approved with a 17-2 vote (and two abstentions) by the parliament’s legal affairs committee.


Among many other issues addressed, the report considers:

  • The question of legal status: “whereas, ultimately, robots’ autonomy raises the question of their nature in the light of the existing legal categories – of whether they should be regarded as natural persons, legal persons, animals or objects – or whether a new category should be created”, advancing with the proposal of “creating a specific legal status for robots, so that at least the most sophisticated autonomous robots could be established as having the status of electronic persons with specific rights and obligations…”
  • The impact of robotics and AI on employment and social security, and concludes that “consideration should be given to the possible need to introduce corporate reporting requirements on the extent and proportion of the contribution of robotics and AI to the economic results of a company for the purpose of taxation and social security contributions; takes the view that in the light of the possible effects on the labour market of robotics and AI a general basic income should be seriously considered, and invites all Member States to do so;”
  • The need for a clear and unambiguous registration system for robots, recommending that “a system of registration of advanced robots should be introduced, and calls on the Commission to establish criteria for the classification of robots with a view to identifying the robots that would need to be registered;”


How to create a mind

Ray Kurzweil’s latest book, How to Create a Mind, published in 2012, is an interesting read and shows some welcome change on his views of science and technology. Unlike some of his previous (and influntial) books, including The Singularity is Near, The Age of Spiritual Machines and The Age of Intelligent Machines, the main point of this book is not that exponential technological development will bring in a technological singularity in a few decades.


True, that theme is still present, but takes second place to the main theme of the book, a concrete (although incomplete) proposal to build intelligent systems that are inspired in the architecture of the human neocortex.

Kurzweil main point in this book is to present a model of the human neocortex, what he calls The Pattern Recognition Theory of the Mind (PRTM). In this theory, the neocortex is simply a very powerful pattern recognition system, built out of about 300 million (his number, not mine) similar pattern recognizers. The input from each of these recognizers can come from either external inputs, through the senses, or from the older parts (evolutionary speaking) of the brain, or from the output of other pattern recognizers in the neocortex. Each recognizer is relatively simple, and can only recognize a simple pattern (say the word APPLE) but, through complex interconnections with other recognizers above and below, it makes possible all sorts of thinking and abstract reasoning.

Each pattern consists, in its essence, in a short sequence of symbols, and is connected, through bundles of axons, to the actual place in the cortex where these symbols are activated, by another pattern recognizer. In most cases, the memories these recognizers represent must be accessed in a specific order. He gives the example that very few persons can recite the alphabet backwards, or even their social security number, which is taken as evidence of the sequential nature of operation of these pattern recognizers.

The key point of the book is that the actual algorithms used to build and structure a neocortex may soon become well understood, and used to build intelligent machines, embodied with true strong Artificial Intelligence. How to Create a Mind falls somewhat short of the promise in the subtitle, The Secret of Human Thought Revealed, but still makes for some interesting reading.

Finland flirts with basic income

In an experimental trial started January 1st, 2017, Finland started to attribute a basic social income to 2000 unemployed persons. Unlike a standard unemployment income, this subsidy will still be paid even if the recipients find work.


Under this scheme, unemployed Finns, with ages in the 25 to 58 range will receive a guaranteed sum of €560, every month, independently of whether they have or find any other income. This value will replace other existing social benefits. A number of articles, including this one, in the Guardian, provide additional information about the scheme.

The move comes on the wake of a promise made by the centre-right government coalition elected in 2015, to run a basic income pilot project. The objective is to address concerns related with the disappearance of jobs caused by technological changes.

Other countries, cities and regions are running tentative experiments in basic income, including the Netherlands, Canada and the city of Livorno, in Italy. However, many concerns remain about whether this mechanism is the right mechanism to address the challenges brought in by the advances of technology.

Artificial Intelligence developments: the year in review

TechCrunch, a popular site dedicated to technology news, has published a list of the the top Artificial Intelligence news of 2016.

2016 seems indeed to have been the year Artificial Intelligence (AI) left the confinement of university labs to come into public view.


Several of the news selected by TechCrunch, were also covered in this blog.

In March a Go playing program, developed by Google’s DeepMind, AlphaGo, defeated 18-time world champion Lee Sedol (reference in the TechCrunch review).

Digital Art, where deep learning algorithms learn to paint in the style of a particular artist, was also the topic of one post (reference in the TechCrunch review).

In May, Digital Minds posted Moore’s law is dead, long live Moore´s law, describing how Google’s new chip can be used to run deep learning algorithms using Google’s TensorFlow (related article in the TechCrunch review).

TechCrunch has identified a number of other relevant developments that make for an interesting reading, including the Facebook-Amazon-Google-IBM-Microsoft mega partnership on AI, the Facebook strategy on AI and the news about the language invented by Google’s translation tool.

Will the AI wave gain momentum in 2017, as predicted by this article? I think the chances are good, but only the future will tell.
