Math, magic, and machines

All practices of magic or sorcery, by which one attempts to tame occult powers, so as to place them at one's service and have a supernatural power over others - even if this were for the sake of restoring their health - are gravely contrary to the virtue of religion.

The Magic Circle, 1886, John William Waterhouse


We once feared magic--it challenged the order of the time.
Kings reigned, Popes pontificated, and we each had a place.
Magic gave those outside the mansions a dangerous tool. There's a reason witches were slaughtered.

Royalty and the church have kept their hold, as they have, and as they will, so long as we remain mortal. Our deepest fears respond to power's siren of promised heavens, so long as we do its bidding.

And we, for all our noise and talk and chatter, do power's bidding.

Science has proved far more powerful than magicians. Astrology fell way to astronomy, a man from Galilee to Galileo Galilei. Science levels power, makes democracy possible. Rational thought unleashes its own unfathomable powers.


If the folks used to being in power care to remain in power (with the usual divvying up between various hands of plutocrats, church elders, and royalty), they need to make magic matter again.

It looks like they're succeeding.

For a child to have any hope of grasping the universe, she needs a chance to understand how things work.

Some things are easy--clarinets, bicycles, and roller-skates are open-source  machines. You can see the parts, you can directly observe how the parts interact, and you can modify the parts (usually to worse effect) if you want.

Before I learned to drive, my Dad insisted that I learn how a car works, in an era when car engines were still all mechanical, and the parts (mostly) accessible. Cars broke down a lot more then, but we were a lot more capable of fixing them.

All of that is technology, not science, but technology then reinforced the idea that the universe has relationships, and those who mastered those relationships, well, mastered their worlds. When something broke, we had a chance at fixing it, if we  grasped how the parts interacted.

Our world was defined by tangible relationships.

Arithmetic is hard, harder than those of us good at it remember.

Grasping it today may be harder, ironically, because of the calculator. In our rush to create little scholars, we toss away memory tricks because memorization is not necessary in a universe that holds our working memory in external devices. Insofar as we're able to slide the work over to machines, I agree.

A math machine--once my Dad's, now mine. Still works.

We do not memorize the ways machines do, though. We do not create rigid tables of sculpted data on our brains. We create schema, elaborate networks of gossamer, connecting disconnected ideas with one another in an elaborate fabric where ideas rustle together like the flowing waves in a dancer's dress.

When an idea, a concept, a thought does not fit, it's like a wrinkle on that same flowing dress--we rub at it, press on it, maybe rub some spit on it until it, too, becomes part of out schema, sometimes altering it in ways that the thought no longer has its original meaning.
Or we toss it. We do this all the time. 
When we memorize numbers, when we memorize their relationships, when we struggle with our times tables, we are not simply  chiseling ideas onto stone, we are wrestling with relationships.  It's how we learn.

When we confound the binary code of the efficient calculator--so fast, so accurate, so sleek in design--with the chaotic mess of ideas we struggle to weave into what we already know, we lose a place in our universe, the only one that matters, the one we create in our minds.
***
When we lose our sense of arithmetic--never mind algebra, or trignometry, or calculus--but "simple" arithmetic, we lose our chance at feeling how the natural world works, a world that runs on harmonic rhythms.


The loss of these sensuous rhythms makes high school science a ghost, the class reduced to memorizing incantations of imagined power. E = mc2 becomes a mantra, and passing science becomes a sacred rite of passage.

It also becomes pointless.

Your post reminds me of the classic quote from Arthur C. Clarke that "...any sufficiently advanced technology is indistinguishable from magic."

Dear Graham,

I had forgotten about that quote--prescient, as was so much of Clarke's writings.

Helps explain our swing back to magical thinking.
