Ten Years in the Blogosphere

It has come to my attention recently that I started this blog ten years ago back in May of 2007. Since that time I have written 487 posts and had over 120,000 visitors. It’s been a wild ride, to say the least!

I had begun blogging before starting this blog at The Brains Blog and had had some of my paper online since 2002/2003 when I was at the University of Connecticut, but this was my first real exposure to philosophy in the online world. At the time I was in the habit of jotting down ideas in Word documents. Some of these would get developed into conference presentations or papers for a class, but I had begun to accumulate quite a few of them.  At some point in March or April of 2007 I became aware that Pete Mandik had a blog and then found out that blogs were interactive. At that time I hadn’t quite realized that you could comment on the postings at the blogs and up till then I had just been reading the articles. It sounds absurd now but that is the way it happened! I recall we were waking somewhere after some talk or something and someone said ‘oh yeah that’s what’s fun about them!” I began hanging out online and arguing with Pete about his recent paper ‘Beware the Unicorn’ paper and eventually I thought that maybe I should contribute to a blog. I approached Gualtierro Piccinini who was the owner/manager of Brains at that time. He allowed me to become a contributor and I started posting regularly there in April and early May of 2007.

Soon afterwards I got an anonymous email from someone saying that people would enjoy my posting more if I did so less often and that if I had that much to say perhaps I should start my own blog. The email was sent from an anonymous gmail account and whoever it was said they did not want me to know who they were. That was a shock and I was pretty pissed at whoever sent the email. I forget what I said back but I don’t think it was nice. I never did find out who sent that email but I certainly do have my suspicions….Even so, though, they did make a good point. Maybe I should start my own blog, I thought to myself, and so I did!

I was still a graduate student when I started this blog and I certainly had more time to write back then! Once I got my tenure-track job at LaGuardia I had less time to write but blogging here was a very important source of excellent feedback on many of my ideas. I also learned a lot about how online interactions could spiral towards non-productivity. In fact some of the more unpleasant experiences I had here at this blog led me to include some kind of video component when I started the Online Consciousness Conference. I figured that if people could at least see and/or hear the person they were responding to it might change the tone of the conversation. I think it (mostly/somewhat) worked but who knows!

I am hoping to continue to blog here if only to work out my own thoughts about various issues. Just for fun here are some of the more active posts from the past 10 years.

Top 5 most viewed posts of all time (probably due to their being among the oldest but still):

  1. Why does 1+1=2?
    • [August 2007] -The basic mathematical truths are either true because of how the world is or independently of the world. How could we ever know which?
  2. A Simple Argument against Berkeley
    • [May 2008] -“last week I talked to this guy at the DMV who told me I need to file an address change” –are you now thinking of the guy I talked to in a way that defeats Berkeley’s master argument? I think so
  3. What is Wrong with Eating Meat
    • [November 2007] -a vegetarian/vegan reflects on eating meat (brought on by Thanksgiving and the resulting callous humor surrounding killing and eating turkeys). Can we separate the issue of eating meat from that of killing animals?
  4. The Philosophical Method
    • [August 2008] -‘A good argument for the conclusion that P is a reason to believe that P is true’ -I defend the claim that the method of philosophy commits one to reason and argument as a source of knowledge
  5. God Vs. The Delayed Choice Quantum Eraser
    • [February 2008] -If knowing which path a particle takes entails that the particle displays classical particle properties then God, who always knows which path every particle takes, cannot know about the wave-properties of reality. The main pushback to this line of argument was that this is a by-product of our way of coming to know but I think this interpretation of quantum mechanics isn’t right. It is knowing that matters.

A Higher-Order Theory of Emotional Consciousness

I am very happy to be able to say that the paper I have been writing with Joseph E. LeDoux is out in PNAS (Proceeding of the National Academy of the Sciences of the United States). In this paper we develop a higher-order theory of conscious emotional experience.

I have been interested in the emotions for quite some time now. I wrote my dissertation trying to show that it was possible to take seriously the role that the emotions play in our moral psychology which is seemingly revealed by contemporary cognitive neuroscience, and which I take to suggest that one of the basic premises of emotivism is true. But at the same time I wanted to preserve the space for one to also take seriously some kind of moral realism. In the dissertation I was more concerned with the philosophy of language than with the nature of the emotions but I have always been attracted to a rather simplistic view on which the differing conscious emotions differ with respect to the way in which they feel subjectively (I explore this as a general approach to the propositional attitudes in The Mark of the Mental). The idea that emotions are feelings is an old one in philosophy but has fallen out of favor in recent years. I also felt that in fleshing out such an account the higher-order approach to consciousness would come in handy. This idea was really made clear when I reviewed the book Feelings and Emotions: The Amsterdam Symposium. I felt that it would be a good idea to approach the science of emotions with the higher-order theory of consciousness in mind.

That was back in 2008 and since then I have not really followed up on any of the ideas in my dissertation. I have always wanted to but have always found something else at the moment to work on and that is why it is especially nice to have been working with Joseph LeDoux explicitly combining the two. I am very happy with the result and look forward to any discussion.

Do We Live in a Westworld World??

I have not had the time to post here as often as I’d like and I am hoping to get back into a semi-regular blogging schedule once things settle down. The hectic pace of an almost-two-year-old and teaching a 6/3/-6/3 course load (18 classes a year!) has taken its toll. I have been meaning to write a post on my plenary session at The Science of Consciousness (TSC2016) conference in Tucson. And I have been working on a paper with Joe LeDoux developing a Higher-Order Theory of Emotional Consciousness that is nearing the final stages. I plan to post something about it once we are done. I am also still trying to produce a series of videos for my introductory logic class at LaGuardia and will also post something on that when they are finished (hopefully before the Spring semester). So a lot is going on!

But all of that aside I wanted to take a moment to talk about Westworld. I have not seen the original movie by Michael Crichton but I was eagerly anticipating the new HBO series and now having watched it I think it is a wonderful show with a lot of rich philosophical content. There are a lot of interesting questions about consciousness and computation brought up by the show but I wanted to step back and note the clever way that the show introduces a new twist on the some old skeptical worries. There are some mild spoilers below but if you have seen the first episode that is all that you need to follow the argument.

The basic premise of the show involves the existence of a giant park known as Westworld where there are advanced artificial agents that serve as the backdrop for the various adventures of the patrons of the park. These advanced artificial agents, known as hosts in the show, are very lifelike and in fact stipulated to be indistinguishable from flesh and blood humans. The behavior of the hosts is for the most part scripted and under the complete control of the people who run Westworld. When the hosts interact with the ‘newcomers’, i.e. those who visit the park for recreation, they are allowed limited improvisation and mild variance from their scripted behavior but that is all. The feature that is noticeable for our purposes is that the hosts are programmed in such a way that whenever a newcomer mentions anything about the existence of things outside the park they noticeably fail to notice what the newcomer has said. If they happen to see an artifact from outside the park, like a picture, they do not register it and simply say ‘it doesn’t look like anything to me’. Finally, they mention that the hosts have the concept of dreaming, and specifically of a nightmare, in order to ensure that any weird experiences due to park maintenance can be attributed to being in a dream.

That is enough of the plot mechanics of the show to introduce the interesting new skeptical worry. How can we be sure that we are not now, at this very instant, in a Westworld World? That is, given some common assumptions, how can we rule out that our city -NYworld-, our state -CaliforniaWorld-, our country -USAworld-, indeed our planet -EarthWorld- etc, are not actually vast artificial environments run by external agents set up for the enjoyment of ‘newcomers’ (tourists?)? It is true that I do not notice any evidence that the Earth is just an artificial environment with automatons populating it. But this is consistent with my actually being an artificial agent of some sort whose internal programming, or what ever is equivalent to that, prevents me from noticing any such evidence. In the most severe form EarthWorld might be an amusement park for an alien race. A place where they go to vacation and reek havoc. We may have interacted with any number of alien beings and simply not have noticed that they have tentacles, four eyes, etc. We may be constructed to take their appearance to conform to normal human standards (after all many take physics to already demonstrate that we don’t perceive reality as it is).

In a sense this is related to the Simulation Hypothesis. In that case Bostrom and others consider the possibility that our reality is in actuality a computer simulation, like The Sims but more advanced. This is not the kind of scenario envisioned in EarthWorld. There the idea is that we have an actual physical place, The Earth, complete with physical elements, trees, animals, wind, etc and also artificial agents, ourselves. Our role in EarthWorld may vary depending on the skeptical scenario one envisions but one scenario is that we are highly advanced artificial agents with advanced AI and limited conscious experience (that is we are phenomenally conscious but miss out on a large portion of what is actually happening around us). This is not a computer simulated reality but is still an artificial reality of sorts. Maybe more akin to Live Action Role Playing than to computer simulation (maybe Artificial Action Role Playing?).

As with most skeptical scenarios I don’t think we have to accept the conclusion that we are indeed in such a scenario but it is, I think, an interesting new take on the ‘we might be conscious computer programs in an artificial environment’ trope. As such I also think that the simulation argument, if it works at all, works equally well for Earthworld and so if you think we might be in a simulation you should also think we might be in Earthworld.

Consciousness and its Place in Physical Reality

In the Spring 2013 semester I initiated a new course at LaGuardia that had the theme Cosmology, Consciousness, and Computation. The basic idea was to explore issues relating to physicalism. Intuitively, physicalism is the view that everything that exists is physical but what is the nature of physical reality? The idea I had was to have the couse divided into three sections. In the first section we would do a conceptual physics course talking about the development of physics from the ancient world to the present day. Then we would turn to issues about consciousness and mind and where they fit in the physical picture we have so far developed. After that we turn to issues about computation; Is the universe computable? Or perhaps does it instantiate some computation? Is consciousness computational? Are we living in a simulation? Is the universe a hologram?

In my quest to have low cost book options for students I have adopted the Terminator book I co-edited and have supplemented that with readings from the Stanford Encyclopedia of Philosophy and other online material. The reception to the course was very good and I am really looking forward to doing it a second time in Fall 2013. I have updated the syllabus and, as usual, would welcome any suggestions or feedback.

Spring Ahead

The Spring semester is up and running here in nyc! I have been ultra busy and it looks like there is no end in sight…it is getting harder and harder to find time to write substantial posts (frivolous ones too) but I hope that I will be able to do a bit more this Spring. In the meantime here is a round up of what has been going on in the new year.

Besides preparing to teach my super cool class on Cosmology, Consciousness, and Computation for the first time I have been doing a lot of writing and have finished a few papers (it turns out when you don’t teach during the break you can get a lot done!). One is The Two-Dimensional Argument Against Dualism, which is a product of my presentation at Tucson 2012 and the discussions it prompted. As a result of all of this I have come to understand some of the key issues a lot better and I think this is the clearest statement of the issues yet. Any feedback on this is highly appreciated! Another is David Chalmers on Mind and Consciousness which is forthcoming in Philosophy of Mind: The Key Thinkers edited by Andrew Bailey. The goal? Explain Chalmers’ views on mind and consciousness to someone who was unfamiliar with them in 6,000 words or less. I’ll let posterity judge to what extent I succeeded. (btw completing the Chalmers 2013 trifecta is my review of Constructing the World for The Philosopher’s Magazine which should be coming out later in February…1,700 words to review a book that is nearly 500 pages of highly technical philosophy? No Problem…it’s a bit like a word puzzle! Incidentally, I may be the only person on the planet who has now read both The Character of Consciousness and Constructing the World back to back and cover to cover!)

I am also planning on being at the Grad Center more this semester. I am going to be be sitting in on David Rosenthal’s class on Mental Qualities. Believe it or not I have never taken this course and so I am excited for it. I am hoping to do some posts on some of the readings and discussions (for instance I was re-reading Nagel’s paper on Panpsychism which seems to anticipate a lot of the themes of recent discussions). In addition the CUNY Cognitive Science Speaker Series looks fantastic and I am hoping to be able to attend more regularly.

And of course coming up shortly is the Fifth Online Consciousness Conference! I can’t believe that it has been 5 years already! The program is nearly finalized (still looking for commenters if you know anyone who is interested). I would really like to thank David Chalmers, Susanna Siegel, Adam Pautz, and John Schwenkler for helping me put together such an awesome program!

Also coming up quickly are a couple of meat space conferences. Sadly I am not able to make it out to the Southern Society for Philosophy and Psychology but Pete Mandik will be there presenting our joint paper On Whether the Higher-Order Thought Theory of Consciousness Entails Cognitive Phenomenology Or What is it like to think that One thinks that P? (with comments by David Pitt). I am sad to miss this conference since it looks like it will be the best one ever but even I have limits 🙂

But I will going out to the apa in San Francisco to present my solo version of the above paper The Phenomenology of HOT Or What is it Like to Think that one Thinks That P?. It’s a funny story because I wrote that and submitted it to the apa before Pete and I teamed up for the co-written one above. Jake Berger is going to comment on this version of the paper and so it should be a very interesting session! Afterwards Pete and I will revise the paper which is slated for a special issue of Philosophical Topics so any feedback would be greatly appreciated as well.

Finally my edited book Consciousness Inside and Out: Phenomenology, Neuroscience, and the Nature of Experience is due to be published in March 2013 and is already listed on Amazon.com! After two years of hard work I am very excited to see this finally coming out! It includes rewritten papers, new commentaries, and new responses, from the participants of the Third Online Consciousness Conference held in february 2011.

Looking ahead past the spring my proposed Symposium was accepted by the Association for the Scientific Study of Consciousness meeting in San Diego. The symposium is titled ‘The Role of Prefrontal Cortex in Conscious Experience” and will feature talks by Rafi Malach, Joe Levine, Doby Rahnev and me. Very exciting!

Shesh, just writing that out is exhausting!
