Being an eternal student, I should report in every now and then as to what I’m currently studying. Recall that I’m an old guy, long out of school. I study things simply for the beauty of it. I’m not taking a course; I’m not going to be graded; I’m not going to get a new job from it. It makes absolutely no difference to anyone or anything that my brain is still stuck in school. Except maybe to me, because I like to do it. So here’s what I’m doing in terms of learning these days:
1.) The Roman Empire
Course Material: CD lecture series “Rome and the Barbarians” by The Great Courses; The Immense Majesty: A History of Rome and the Roman Empire, Thomas Africa; Handbook to Life in Ancient Rome, Lesley Adkins and Roy Adkins.
Initial Impressions: This is where civilization came from? This great empire was built on the subjugation of independent peoples and cultures surrounding the Mediterranean Sea through military aggressiveness. Well, I guess you can’t make an omelet without cracking some eggs; look at what had to be done to native Americans and African slaves in order to build the American empire. If I could make but one suggestion for future generations, it would be “no more empires”. Instead, let’s have a world full of little nation-states about 200 miles wide, tops. They can still build coalitions to do interesting things like explore space or find cures for cancer. But let’s get rid of the big, militarily dominating empires. The break-up of the Soviet Union was a step in the right direction. The European Union, luckily, doesn’t seem destined to become much more than a trade block. And hey, what would be so wrong with Iraq breaking up into three mini-nations?
One good thing about studying the Roman Empire: it helps you to understand science fiction, especially the Star Trek / Star Wars kind. Almost all of the “space invasion” movies (e.g., Fourth of July) and TV shows (isn’t there a new one on ABC these days?) are based on the fear that someday, some Romans from another Galaxy are going to come along and decide that our planet would make a good addition to their empire. In the process, they would do to us what Rome did to Gaul, Spain, Carthage, Greece, Israel, Dacia, Armenia, etc. Or what the early American state did to the Cherokees, Choctaws, Seminoles, Navajo, Mohawk, Sioux, Apache, Crow, etc. Oh dear, a taste of our own medicine. How bitter.
2.) Quantum Theory
Course Material: Introducing Quantum Theory, J.P. McEvoy and Oscan Zarate; Quantum Reality, Nick Herbert.
Initial Impressions: My initial impressions of Quantum Theory were formed long ago. I’ve been trying to figure out just what all the fuss is about since I was in college. Only now am I beginning to realize just how weird the micro-world really is. Only in my old age can I grasp just why the results of the double-slit electron experiment are so strange. Electrons and light particles are really something like traveling blurs or blobs that cover an area much larger than the particle itself, with the particle sort-of existing everywhere in the blob, but nowhere in particular; not until some act of measurement takes place. This blurry blob has wave-like properties; sort-of, anyway. Also, when this blob comes upon a fork in the road, it goes both ways — sort-of. Yup, definitely pretty weird.
3.) Human Consciousness
Course Material: Consciousness, An Introduction, Susan Blackmore; Introducing Consciousness, D. Papineau, H. Selina; The Mystery of Consciousness, John R. Searle.
Initial Impressions: Consciousness at first seems rather obvious. But try to explain it, and it gets kind-of like quantum theory. Eventually, you start talking about a little person in your head watching a screen. And what is inside that little person’s head? Another little person, ad infinitem like Russian dolls? Ultimately, about the only thing we can say about what consciousness is like, is that it’s like being conscious. We more-or-less hit a dead end, maybe a limit of knowledge (just as the Heisenberg Uncertainty Principle acts as a dead-end to knowledge in the quantum world).
I personally think that a lot can be said about consciousness and its place in our experience by studying human evolution and the development of the mind in a child. Compared with other species, we humans have the ability to think abstractly. We use language as the way to memorialize (and share) our abstractions. One of our biggest abstractions is the concept of ourselves. And once we grasp that concept, we start having emotions about it. That’s what consciousness is ultimately all about, an on-going emotional reaction to a jumbled mix of what’s presently coming thru our senses, what we remember, what we believe, what we hope for and fear (consciously and sub-consciously), and what we had for breakfast. Emotions evolved in animal species so as to increase the brain’s activity in response to exceptional conditions (proximity of food, perception of danger, opportunity for sex). Humans turned this higher level of brain processing into an almost constant thing (although we still have increased brain activity during times of danger or sexual arousal; we never completely leave the jungle).
But — nice as all that sounds, it still doesn’t solve the “hard problem”, which is “just what IS this consciousness of feelings???” A lot of consciousness scientists say that we will someday understand the ultimate nature of conscious experience, but the more I study it, the more I have my doubts. Psychologists, philosophers, and neuroscientists are coming up with all kinds of interesting observations about the workings of the brain and the mind; unlike my evolutionary abstraction and “reflective emotions” hypothesis, theirs are carefully specified and supported by empirical evidence (my idea is mostly SWAG, stupid wild-ass guessing). A handful of them seem to think that they’ve said enough, and that the “hard problem” is (or will soon be) satisfactorily resolved. But my impression is that they’ve hardly scratched the surface, and a consensus of experts appears to agree. I personally don’ t believe that such a consensus will ever evolve, unless a wave of mass delusion overtakes the academic world (which does occasionally happen).
Over the past 400 years or so, science has pushed back the shroud of mystery through which humankind once looked upon the world. Earthquakes and lightening and other mighty phenomenon are now explainable and predictable things. At present, the Big Bang remains a bit of a mystery, but superstring theory may eventually explain it. Quantum phenomenon cannot be understood in the way that everyday events in our world are, but we do have scientific and mathematical tools that elucidate the micro-world. They may even make practical use of strange quantum events (e.g., the development of quantum computing). But as to whether or not the mystery of human consciousness will ever yield to mathematical models or computer analysis, that’s the BIG BIG question of the 21st Century (and maybe even the 22nd and 23rd).
