The Privacy of Mental Content

Image result for castle moat drawbridge

Most of us have a sense that there is something about us that is peculiarly private, known only to us, and that the contents of what we call our "mind" are almost (?) definitionally this peculiarly private stuff.

This is why "mind reading" is such a popular magic trick. To have someone pull a rabbit out of a hat is one thing, and all good fun. But to pull out my thoughts from my head? "Think of any number between one and ten ... you are thinking of four!" -- THAT sort of trick is slightly threatening, though in the context of a stage show the threat is of course contained so the audience doesn't flee in horror.

In history-of-philosophy terms Descartes certainly helped codify our sense of ourselves as a tight fortress with a private theatre inside, it is the "I" which "thinks" and which holds itself as its first certitude.

As a consequence and one might say as a mitigation of this sense of privacy, we talk of putting ourselves in other's shoes. I have no direct perception of what you are thinking as we play chess together, so I ask myself what I would do were your position mine.

All this comes in for a lot of philosophical scrutiny. Daniel Dennett, for example, doesn't believe in the private theatre. He contends, if I understand him, that we are only under the illusion that we are subject to private illusions. Furthermore, he doesn't really believe in the notion of putting one's self in someone else's shoes as a way of predicting behavior. He has written, "If I make believe I am a suspension bridge and wonder what I will do when the wind blows, what 'comes to my mind; in my make believe state depends on ... my knowledge of physics." Why, he asks, should my making believe that I am you be any different. I must have "knowledge of the imitated object" for the make believe. The make believe doesn't drive the knowing.        

The Intentional Stance (1987).

The usual response, of course, is that I am relevantly similar to the other chess player in a sense in which I am not relevantly similar to a suspension bridge.

England as a Raft?

In a lecture delivered in 1880, William James asked rhetorically, "Would England ... be the drifting raft she is now in European affairs if a Frederic the Great had inherited her throne instead of a Victoria, and if Messrs Bentham, Mill, Cobden, and Bright had all been born in Prussia?"

Beneath that, in a collection of such lectures later published under James' direction, was placed the footnote, "The reader will remember when this was written."

The suggestion of the bit about Bentham, Mill, etc. is that the utilitarians as a school helped render England ineffective as a European power, a drifting raft.

The footnote was added in 1897. So either James is suggesting that the baleful influence of Bentham, Mill etc wore off in the meantime or that he had over-estimated it.

Let's unpack this a bit.  What was happening in the period before 1880 that made England seem a drifting raft in European affairs, to a friendly though foreign observer (to the older brother…

Cancer Breakthrough

Hopeful news in recent days about an old and dear desideratum: a cure for cancer. Or at least for a cancer, and a nasty one at that.

The news comes about because investors in GlaxoSmithKline are greedy for profits, and has already inspired a bit of deregulation to boot. 

The FDA has paved the road for a speedy review of a new BCMA drug for multiple myeloma, essentially cancer of the bone marrow. This means that the US govt has removed some of the hurdles that would otherwise (by decision of the same govt) face a company trying to proceed with these trials expeditiously. 

This has been done because the Phase I clinical trial results have been very promising. The report I've seen indicates that details of these results will be shared with the world on Dec. 11 at the annual meeting of the American Society of Hematology. 

The European Medicines Agency has also given priority treatment to the drug in question. 

GSK's website identifies the drug at issue as "GSK2857916," althou…

Francesco Orsi

I thought briefly that I had found a contemporary philosopher whose views on ethics and meta-ethics checked all four key boxes. An ally all down the line.

The four, as regular readers of this blog may remember, are: cognitivism, intuitionism, consequentialism, pluralism. These represent the views that, respectively: some ethical judgments constitute knowledge; one important source for this knowledge consists of quasi-sensory non-inferential primary recognitions ("intuitions"); the right is logically dependent upon the good; and there exists an irreducible plurality of good.

Francesco Orsi seemed to believe all of these propositions. Here's his website and a link to one relevant paper:

What was better: Orsi is a young man. Born in 1980. A damned child! Has no memories of the age of disco!

So I emailed him asking if I was right that he believed all of those things. His answer: three out of …
