Socrates Cafe ...

I was at the local Socrates Cafe meeting in Montclair a few evenings ago (yes, after 4 years I’m back with them). That night, the group seemed to lack its usual enthusiasm for coming up with a multitude of topics for discussion, and then weaning them down through a balloting process. So I threw out an idea that had been rattling around in my head, about the nature of morality and ethical behavior in humans. I.e., is it more social or innate? Does morality originate within each of us (or many of us, or at least some of us) and then somehow get co-opted by the human collective (as laws, ethical notions, shared moral values)? Or does it somehow emerge from the group, and is then assumed by the individual through osmosis (at least in the better of us)? Given the lack of inspiration on anyone else’s part that night, my idea was quickly accepted.

Well, this turned out to be a good topic, as it inspired about 90 minutes of intense and wide-ranging discussion. I can’t say that I left the room with a conclusion; a lot of the discussion frankly veered off from the intended subject. But that’s OK, Socrates Cafe is all the more charming for its lack of academic discipline. What did interest me was the reaction that one of the men in the group had. This fellow, who I respect greatly, is in his late 50’s or early 60’s, and is employed as a bio scientist. I would describe him as “logical positivist” in outlook. He appears to believe that science is the best answer to humankind’s dilemma. He feels that notions of God or gods or spirits or inner spiritualities are hardly necessary. Science explains more and more of our reality, in a very definitive and useful fashion. There’s hardly anything left to the realm of mystery anymore.

So in response to my question,  »  continue reading …

◊  BOOK TIME
Brain / Mind ... Science ...

I just finished reading a book by Paul Churchland about the human brain and its neural network architecture (“Engine of Reason, Seat of the Soul”). This book might be the best available introduction to neural networks and how they make things happen in the brain. It’s not highly technical, but it’s not light reading either; you need to be comfortable around basic scientific and math concepts. But if you can slog your way through it (it’s a slow read), Churchland will reward you with a lot of enlightenment about the operating system of the brain, about how things work below the level of thoughts and feelings and moods and sub-conscious motives, i.e. the paradigms of ordinary psychology. He gives you the basic outline of how small webs of brain neurons (small components of the brain) respond to signals coming in from the senses, as to translate these little blips of ion charges into something having meaning to the higher decision-making parts of the brain; e.g., how they identify a particular face, or a taste, or a color, etc. based on past experience.

These higher areas themselves turn out to use the same techniques to bring together all of these sensory impressions, weaving them into an overall picture of where you are, what you are perceiving, what you think or feel, what you remember, and what you plan to do (or not do). Pretty interesting; it’s not the final blueprint for how the mind works, but it does explain what the primary building blocks are like.

After his introduction to neural networks in the first half of the book,  »  continue reading …

Personal Reflections ...

I had to take my car to my regular mechanic the other day for some servicing, and it gave me an occasion to ride a bus. Or, “the bus”, as we say here in Jersey. The bus route in question was the NJ Transit number 75, a rush-hour only express service from Newark to Butler. And I must say that I enjoyed the ride. NJT uses a big, smooth-riding MCI cruiser on this route, not just another Nova street-rattler. The ride was smooth and quiet, and open seats were plentiful. The driver made change, which doesn’t happen on most buses out of Newark. It was a nice day and the sun was shining through the big windows. Everyone on board was well-mannered, no radios or bad behavior. And the trips were more or less on time.

Riding local buses, though, is not easy (and not always pleasant! especially when they are standing room only, or you go through the wrong neighborhood). You have to invest some time and research into finding out when they run, where they stop, how much they charge, how and when you pay for the trip, etc. And even when you’re on board, if you’re a first time rider, you might not know the protocol to use when your destination nears and you want to get off. Maybe there’s a strip or button that you press on the bus to ring a bell telling the driver to get ready to stop. But when you’re not a regular, sometimes the driver still won’t stop; unless you walk right up front and tell him or her. And if you do, the driver might get a little surly about being told, implying that you are bothering her or him with unnecessary details. (And if you do happen to be on a local bus going thru the wrong neighborhood — just stay calm and quiet, stay loose, don’t move too much, and look at the floor or out the window mostly.)

Even getting on the bus is not always easy; some bus drivers  »  continue reading …

Politics ... Public Policy ...

It now looks like America is going to get comprehensive health care reform after all. President Obama has shown his willingness to burn many political bridges to close the deal. There may still be a lot of sparks and friction getting sufficient votes in the House, and the Senate reconciliation process will cause a lot of squawking from the Republicans. But it looks to me like Obama is going to get a big new legislative plan for health care passed while the tulips are still blooming here in the northeast.

I’ve already written about my apprehensions regarding the ObamaCare approach, i.e. much government oversight and control over health care providers and insurers (along with many new requirements and fees for both individuals and businesses). I agree that there is a health care crisis in America. And I think that the heart of the problem is costs. Health care is much more expensive now than it was going back thirty, twenty or even ten years.

Since 1970, health care costs have risen at a rate  »  continue reading …

Personal Reflections ...

It’s early March, and the signs are in the air that another winter is coming to an end. There’s a few minutes of daylight when I get home from work now. The cold winds still blow, but they aren’t as frigid as they were four weeks ago. The weather forecasts still threaten us with snow, but mostly mixed with rain and slush.

I haven’t seen any bulb plants (daffodils, crocuses) poking up thru the muddy, snowy ground yet; but I have seen robins up in the trees. Usually you see them on the ground, looking for worms; but that protein source will not be available for another week or two. In the interim, they probably know how to find other kinds of birdfood, like the sparrows and starlings survive on. They obviously were thinking of the recent mild winters we’ve had here in the Northeast. Surprise, this one was like the olden days. But the tougher the winter, the sweeter it is once it’s over. Or almost over, which is where we are right now.

This was my first winter since my mother died back in October. It’s been  »  continue reading …

Current Affairs ...

Since Sept. 11, 2001, we’ve not had a major terrorist attack on U.S. soil. I would not have believed that on the evening of 9-11. Through a combination of response and dumb luck, our government has managed to protect the American public from the horrors of ideological death and destruction, a horror that has become too familiar in other parts of the world. Our “homeland security” protections on American soil, together with our international intelligence efforts and pro-active military involvements (too proactive, perhaps, in the care of Iraq) have stopped another “big plot” from hatching in one of our cities. For that, we must all be grateful.

Unfortunately, while the big plots haven’t gotten anywhere, a different kind of terrorism has asserted itself in recent years, with small but fatal consequences and unsettling implications. I’m thinking about the “one man”, self-inspired terrorist plots, such as the shooting spree by Army Major Nidal Malik Hasan at Fort Hood, and the airplane explosion attempt by Umar Farouk Abdulmutallab over Detroit on Christmas Day. These kinds of terrorism are harder to detect and stop. They involve a certain kind of person with a certain mentality, who absorbs an “idea in the air” like an infection; i.e. what some psychologists and sociologists call a “meme”.

It only takes one big, well-publicized terror incident (e.g., 9-11)  »  continue reading …

Current Affairs ... Personal Reflections ...

It’s a workday but I’m staying home because of the big snowstorm over the New York metro area. The birdfeeder outside my window is extremely popular this morning, attracting birds that usually don’t want to get close to human territory. These include juncos, which are also known as “snowbirds”. Over evolutionary history, birds evolved from reptiles; their feathers are really just modified lizard scales. So, those juncos, like all the other birds jumping around in the feeder box out there, are in effect ‘flying lizards’.

This storm is being called a “blizzard” by some of the more flamboyant local news reporters (I don’t think it really meets the technical qualifications for very low temperature and high wind). So if it takes a blizzard to bring juncos to my window birdfeeder, perhaps I should think of them as “blizzard lizards”.

Yea, I know, that’s kind of stupid. But that’s what cabin fever will do to you.  »  continue reading …

Religion ...

I’m still slowly plowing through a book by philosopher Paul Churchland about neural networks and the profound implications they have for understanding how our brains and minds really work. The book is called “The Engine of Reason, The Seat of the Soul”, and it is good. Churchland gets down to some nitty-gritty on what neural networks are and how they work (well, he can’t exactly give examples, as the mechanisms by which these networks behave are still quite complex, even though they ultimately ground themselves on fairly simple logical rules; in other words, you can’t just go out and build your own neural network on a computer after reading this). And then he goes into all of the implications for philosophy, psychology and even sociology.

I will say that if you can follow him, you will think of the mind in a somewhat different way than you did previously. I hope that psychology majors are learning this stuff. And sociology and philosophy majors too. But then, should we go the next step, into religion? Well, Churchland certain does.

Neural networking is the process by which the brain  »  continue reading …

Socrates Cafe ...

I went to the local Socrates Cafe meeting the other night, for an interesting discussion about God. The topic for the evening, suggested by a young medical school student from the Middle East, was whether God exists. Yes, the young student made it clear that he comes from the Islamic faith tradition. However, the science and high-tech environment of western medicine was giving him some . . . well, perhaps not doubts about God, but some second thoughts anyway. He said that he was reading some books by evolutionary biologist Richard Dawkins, who of course goes totally nuclear against any notion of a transcendent creator and sustainer in the universe. So, the young fellow with the beard had come to the local half-assed western philosophers, to see what they had to say about it.

This was quite interesting and special. I myself have lived a sheltered life, relative to the Islamic world. I really haven’t known too many Muslims; and the few that I have known weren’t / aren’t very up-front about it. They are mostly just average Americans, trying to get by; their religious practice and heritage just happens to be Islam. This young doctor-to-be wasn’t really all that different. However, he certainly did care about God, and was open-minded enough to reach out beyond the counsels of the local mosque or imam to talk about “it” (i.e., the question of God’s existence).

The group was rather small, only myself, the moderator,  »  continue reading …

Spirituality ...

I’m engaging in some theology tonight. Simplistic theology, however, since over dinner I had a chocolate imperial stout that weighs in at 11% ABV (Southern Tier Choklat).

OK, so the question is God. And there is no answer; it’s pretty clear that there will never be one in this life. So why isn’t there an answer, why can’t there be one? Maybe because, if there was an answer, we would take God for granted. And for God to be God, we could NOT take God for granted. But if we were sure that God existed, surely we would; that’s just the way we are. So, if we could know for sure that there was a God, there couldn’t be a God. Simple as that! (At least after a bottle of imperial stout! But then again, Ben Franklin said that beer is proof that God wants us to be happy . . . ).

There are two, maybe three problems that we commonly have about God.  »  continue reading …
