I do not believe there is evil in nature. The natural world simply operates as it does, without morals or reason, plainly in response to stimuli in the short term (action) and the long term (evolution). Nature is a system. Evil, like good, is a purely human issue; we interpret some things that happen one way, some another.
I am not dismissing good and evil as unimportant, I'm simply saying they exist solely in the domain of human experience, not nature. I am neither suggesting we should, in a Nietzschean sense, seek to ignore this distinction by synthesizing a higher truth*; I believe some things are, in fact, evil.
But where does evil come from?
The men who shot 14-year-old Malala Yousafzai in the head four times simply because she believes girls should be able to go to school committed an evil act. How were they able to do such a thing? Because they are evil people? I think that's likely too simple an answer.
Timothy McVeigh, when he blew up a building full of people in Oklahoma City, committed an act of evil. The 9/11 hijackers did evil. The Nazi's attempt at genocide was evil. There is undoubtedly evil in the world, and all of it is created by people.
If we set aside the actions of the completely psychotic, what remains is a clear through-line that connects in commonality much of human evil, and that is certainty.
The men who shot Malala did so because they believed this to be the will of Allah, whom they believe to be the one true god; that girls must not be educated as boys, and that her contrary beliefs and actions meant it was right to kill her. They did not see it as an act of evil. They rather saw her as enacting an evil in the eyes of god.
But they did not just "suspect" this, for any uncertainly in them would have prevented them from this horrific action. If they had said "I think god wants me to shoot her, but I could be wrong about that" then I submit they would never have actually fired their weapons. They might have argued against her, tried to stop her, reviled her to others, but to actually attempt to end her very life, at 14 years old, they had to be absolutely certain that they were righteous in their action.
Timothy McVeigh, similarly, believed that the United States federal government was an evil force that was destroying the fabric of this nation and our freedoms, and that this constituted a war against its citizens. He saw himself as a freedom fighter, and that attacking a federal building was a justifiable act of war against his oppressors. He didn't consider this as one possible interpretation of the situation, with other possibilities also arguably true, he was absolutely certain he was right, or he would never have taken the lives of so many strangers who had, directly, done nothing to him whatsoever.
The 9/11 bombers were certain they were right. So were the stormtroopers.
There is danger in nature. A tidal wave can drown you, a grizzly bear can eat you, a slip off of a cliff will subject you to gravity and a deadly fall. But none of this is evil, it just is. Evil is in the hearts and intentions of people who are certain, absolutely certain, that they know the truth and that this knowledge justifies acts that would otherwise be evil, but are not evil because of some larger, more important truth. In the main, I doubt that there are evil people, people who simply want to do bad things while cackling to themselves and twirling their mustaches. I think most evil is done by people who see themselves as certainly doing the right thing, and they are so sure of this it enables them to commit the most horrible acts imaginable.
I'm not saying that certainly is the only source of evil. Greed can cause it, anger can, selfishness can, etc... but an awful lot of evil is committed by those who intend good, but are simply deluded by their certainty.
The cure, of course, is credulity. We must question everything; our government, our teachers, our priests and rabbis... but mostly ourselves and what we believe. We must never allow ourselves to disregard the possibility that the things we hold the most true may be completely wrong, and that the things we see as lies and foolishness may be correct.
Of course, that means I must doubt the very notion I am putting forth in this blog, and I do. But to doubt does not mean to dismiss, or even disbelieve. It means that I would never take an extreme action based on this belief. I would never say that it is okay to kill people who operate with certainty because I believe certainty is a major source of evil in the world.
This belief motivates me to avoid certainty in myself. I do not believe there is a god, but I may be wrong. I believe the second amendment is not about individual gun ownership, but perhaps I am in error. I believe abortion should be legal but rare, but I'm willing to entertain other opinions. I do not lack conviction in my beliefs.
I lack certainty.

The Sculptor
You never know where an insight will come from. I've been designing software for over 35
years, but it wasn't until the last 10 that I came across Christopher
Alexander's "The Timeless Way of Building" (an architecture book) because of a recommendation by
Alan Shalloway, when I joined Net Objectives.
I learned a lot from Alexander, but one thing I could never
quite understand was the one thing he said was actually the main thrust of the
book, namely that you should favor "design by differentiation" over
"design by synthesis". The
latter I kind of understood: building things by finding pieces and then putting
together whatever you can with the pieces you found. I'd done that for years -- ask the customer
for details about the problem domain, make those things into objects, and then
create an object-oriented design based on the objects. This seemed reasonable, and after all what
else could one do?
But Alexander said to disfavor this approach in deference to
"design by differentiation". His
description of what "differentiation" actually is however, totally eluded
me. So I understood that the approach I
took was not such a good one, but the better way was incomprehensible to
me. Frankly, this was kind of
frustrating.
But then I got... lucky. I tend to. I happened upon a very kind and helpful man who, unknown to himself, resolved this conundrum for me entirely. He was, in fact, a sculptor.
I was perusing the Bellevue Art Walk with my wife, Andrea.
She is a very skilled artist, and we go to these fairs pretty regularly because
she has an abiding interest in art. The
Art Walk consists of blockading several blocks around Bellevue Square
(disallowing traffic) and inviting artists to display their works to the
pedestrians.
I like art, but the art fair is not my favorite venue to
enjoy it in; they are usually conducted on very hot days, and I seldom see any
artist selling any art, so I find them kind of depressing. I often wonder how these people are able to
feed themselves. Anyway, we'd been there
for about an hour, and I was grumpy. I
was sweating in the summer heat, and totally bummed about the failure of the
artists I saw to sell anything at all. I
told Andrea this, and she suggested we stop for an iced coffee, to cool off and
cheer up. It seemed like a good idea to
me.
The thing is, and here's the lucky part, they had designated
the parking lot of the local coffee place as the "scupture garden",
and thus all the sculptors were there in a large group. In order for me to enter the coffee shop, and
thus to get my coffee, I would have to pass by them all. Otherwise, I would not have paid them much
attention, given how out of sorts I was.
I had no choice, however.
It turned out that two of the sculptors, one at the entrance
of the garden and one at the far end (at the front door of the coffee shop) had
by happenstance chosen the same subject matter; a particular kind of fishing
bird called an osprey.
An osprey hunts in a most unusual way; as it flies above the
water it looks for the shadows of fish that are just under the surface. Seeing one, the bird simply folds up its
wings, extends its talons, and starts to fall from the sky, like a stone. It is a large bird, and can quickly pick up
speed in this way. By the time it
strikes the water, feet-first, it is moving so fast that the fish has no
chance to react before it is in the clutches of the bird's very sharp talons.
But, now the bird is in danger of plunging into the water
itself and, being not-a-duck, does not want to.
It would surely drown. So, at the
last minute, the bird unfolds its massive wings and, beating back against the
air, reverses direction abruptly and emerges from the splash up into the sky,
flying away with its prey as the splash collapses just beneath the bird. An amazing thing to behold, this, and it was
the very moment that both sculptors had chosen to capture.
Showing movement in sculpture is tricky, and they both had taken on the challenge in different ways. The first sculptor along my path was the sort of artist who, I am imagining, goes into a junkyard or rubbish pile, and finds pieces of interestingly twisted metal, odd shapes of industrial machienery, and so forth. Taking these items back to his shop, he assembles them into an abstract representation of his subject matter. His product was interesting, but frankly I (as a rather naive art critic) could not really see the bird in what he had done. I'm sure that's what the artist intended; not a literal representation of the bird, but an expression of... his own reaction to it, or something like that.
But the other sculptor, at the opposite end of the garden,
was the sort of artist who works with what I considered to be more traditional
methods, they way sculptors in the movies seem to always work. Take a block of marble and, using chisels and
drills and so forth, create a literal representation of your subject
matter. His osprey looked more like a
real osprey to me.
In fact, this piece was unlike the typical artwork. In my experience, most art requires that you
stand back a little in order to appreciate it.
Get too close, and it begins to lose its beauty. This piece, however, looked better and better
as I got closer to it; and thus I ended up standing directly in front
of it with my mouth hanging open. It was
amazingly impressive and realistic-looking.
The sculptor noticed my interest and, obviously hoping for a
sale, sidled up next to me and said "you like that, do you?"
"Yes!" I replied.
Then I noted the price tag.
"And if I had $16,000 to spare, I'd love to buy it. But I don't."
He smiled. "No
problem, glad you enjoyed it anyway.
Someone will buy it eventually."
But then it struck me.
The first sculptor, what he had done; wasn't that design by
synthesis? He started by looking for parts,
and then made what he could make given the nature of the parts he happened to
find. Isn't that like looking for
objects and then trying to assemble them into a structure? In fact, I recalled Alexander saying that a design by synthesis lacked "the character of nature." I noted that his
osprey didn't look nearly as real as the one the second sculptor created. So, maybe what the second sculptor was doing was
an example of design by differentiation.
Of course, I had no idea how such a sculpture is created. So I said "I don't want to take up your time since I'm not a potential customer here, but do you mind if I ask you some questions about how you did this?"
Of course, I had no idea how such a sculpture is created. So I said "I don't want to take up your time since I'm not a potential customer here, but do you mind if I ask you some questions about how you did this?"
He was very nice and said I should ask him about anything
that interested me. The problem was, I
was not sure what I wanted to ask, exactly.
So I started with an obvious one: "How do you begin? Do you work from photos of ospreys, or
drawings, or actual birds? Do you go to
the zoo? Do you bring a bird back to
your studio to observe it?"
He said "In the beginning, the bird is not
important."
This surprised me.
"Really? Well... then what
is important?"
He smiled. "The
money," he said. "I rarely work
without a contract. I don't just sculpt
things in the hope that maybe, someday, someone will buy it. I did in this case, but that's rare. Usually I work on commission."
Makes sense, I thought.
I don't work for free either.
"So, let's say," he continued, "that you have
a new building scheduled to open in the fall, and you want a sculpture of, say,
a hunting osprey for the lobby. You
contact me with the request and we work out how much I'll be paid, how much I
get up front, what budget I have for purchasing the marble, when it needs to be
completed, and so forth."
"I get you. But
then, what representation of the bird do you use?"
"None," he said.
"It's too early for that."
As the conversation continued, it became clear to me that there was a
lot he had to do and discover before even contemplating the actual bird itself.
First, he would need to visit the actual site, the lobby in
this case, where the sculpture would eventually be installed. He'd need to know the dimensions of the area
(to ensure the finished work would physically fit into it, and also be
attractive and "right sized"), he'd need to know the color scheme of
the surroundings (marble comes in lots of colors, and a pink artwork in a blue
enviroment would look clownish), the patterns of light entering the room at
various times of the day, where visitors in the lobby were going to sit, and so forth.
The environment where the completed work would be installed must be
taken into account before beginning the work.
Also, once armed with these notes, he would have to visit a
marble quarry and seek out a piece that was of the right size, the right hue,
and which he could afford given the constraints of his contract. There may be only one piece that would fit
all the constraints and requirements and limits.
Having purchased the marble, he would take it back to his
workshop and examine the raw material.
Each piece of marble is different; they all have different grain
patterns, flaws and cracks, weak and strong points, and if the sculptor is not
highly aware of these then his work might fracture or even crumble into pieces
before it is complete or when he tries to move it to the installation
location. Only certainly things are
possible with a given piece of marble.
What I realized from this was that the sculpture started not
with the subject, but the context in which the subject would be placed once it
was completed. Again, recalling Alexander, I remembered his phrase "design by context."
"When does the bird come into it?" I asked.
"Right about now," he said. He had taken photographs of ospreys hunting
in the twilight hours, which is their preference, and then blew the pictures up
large and mounted them on the walls of his studio. He particularly focused on images of that
critical moment when the bird is emerging from the collapsing splash, taken
from various angles.
"Okay, so now the actual work begins, " I
said. "How does that go?"
He explained that what he liked to do what sculpt the entire
piece, from the tip of the beak to the end of the tail-feathers, from the arch
of the wings to the talons with the fish captured, very quickly and very
roughly. In a scant few days, perhaps a week, he would
have a completed piece; but everything would be very vague. The bird's head would be a simple oval, the
talons like orange traffic cones, the wings just large triangles, etc... complete, but very little detail or nuance.
Having completed the work, he would stop, look at it, look
at the photographs, think, and then take it on again; the whole piece from one
end to the other, but on this pass over the work he would be adding just a bit
more detail to each part he encountered.
Having completed the second pass, over another few days, he would stop,
look at it, look at the photographs, think, and start again. More details would be added on the third
pass, and on and on and on.
As he was explaining this to me I began to think about my
industry, software development, and how in the past several years we've been
changing the way we work. Where we used
to think of software as an activity conducted in discreet phases (analysis,
design, coding, testing, deployment) we've been moving toward more incremental
approaches, as suggested by eXtreme Programming, Scrum, Lean-Agile, and the
like. In each increment we do everything
from analysis to testing, over and over again.
So I said "I'm a software designer, and I have to tell
you that we're doing something similar when we make our products these
days. I think I know why we do that, but
tell me, why do you do that? Why do you
work in an incremental fashion like that?"
"I started doing this because of the schedule
commitment that my customers almost always want. When I promise to deliver a sculpture in 6
months, I do so in good faith. It is my
best guess that the thing will really take 6 months to complete, but in fact
I'm probably wrong. I find it devilishly
difficult to estimate how long a given piece will take because in reality while
they share some similarities with other works I've created, no two sculptures
are really enough alike that I can tell you how long the next on will
take. It's my best guess, that's all."
I didn't say anything, but I thought "man, I know just
what you mean. I have the exact same
problem."
By working in this way, he explained, it meant that when the day came to deliver the finished piece he would have something complete and ready to display. "It might not be the best thing I could ever do," he said, "but it will be the best I can do in the time alloted, and it will be very good. If, on the other hand I just focused on one part of the bird, say the head and shoulders, and refused to move on until it was perfect... it's possible that the deadline would arrive and all I'd have is a head, shoulders, and a huge chunk of raw marble. That's not going to be acceptable to my customer."
All of this washed over me, and got me thinking about the
concept of "design by differentiation" that Alexander had talked
about. I thought the key to
understanding this was almost in my grasp, if I just sat down and thought about
it. I thanked the sculptor for this time
and started to head to the coffee shop for the iced coffee I'd originally
wanted, and some time to think.
"Wait," he said, stopping me and smiling. "I have not told you the most important
part."
"Oh? What's the
most important part?" I asked.
"This sculpture, the one you were so impressed
with? No deadline. I just had this idea and wanted to get it
into stone before the inspiration passed.
I hope someone will buy it some day, but in this case there was no
commission, and therefore no schedule.
Nevertheless, I did sculpt it in that same incremental fashion."
"Why?" I asked.
"You had no limit, you could have done it any way you wanted
to."
"Because," he explained, "it's the only way
to do it. I started working this way due
to practical concerns, but now that I've learned how to approach sculpting
incrementally I know it's the right way to proceed anyway."
"What do you mean?"
He smiled again.
"Come here," he said, motioning me with his hand, "and
look closely at the osprey. I'm going to
tell you something about it and you're going to agree with me, but you won't
know why you're agreeing. You'll just
know I am right."
He really had my curiosity going now. He pointed to the bird's eye and said
"see how the pupil of the eye is angled relative to the beak? Yes?
Okay, remember that, and move around to the other side and look at the
bird's back." He pointed out, on the broad powerful back of the bird, that
one could sense, under the feathers, just how the muscles were flexed. He asked if I could sense that and I said
that I certainly could.
"Here's my statement: given the position of the pupil in the bird's eye, that is how the
muscles would have to be flexed. Or,
conversely, given the way the muscles in the back are flexed, the pupil would
have to be positioned the way it is.
Otherwise, it simply would not be right."
I looked, I thought, and he was right. I could not explain why, but these things
matched... somehow. He went on for about
15 minutes pointing out similar things.
Because the bird's tail was angled downward, the tips of the wings had
to have a slight upward bend. Because
the talons were extended unevenly, the beak had to be slightly open and there
needed to be a small bump on the back of the neck. Because of this, that. Because of these things, those things... on
and on. And I realized that I, since my
early childhood, had seen birds in various situations and my mind had absorbed
all these myriad details about what they are like, how they move, their essential
nature... things I cannot really explain or describe, but when I see them I
know them, and I respond because my mind says "that's right, that's how birds really are."
This was why I'd been so impressed with the piece in the
first place. It looked real in ways that
spoke to my subconscious appreciation of nature, and this created a profound
effect in me.
I explained my theory to him, and he nodded. "That's right. Everything is the way it should be, and you
felt it. It worked because a million
little details are correct."
"That's amazing!" I said, "you're clearly a
genius. How in the world could you
possibly get all those details correct?"
His eyes twinkled at the compliment, but then he said, with
a laugh "you've got me. I have no
idea. It's too complicated, too subtle,
too nuanced for a mere human like me to ever hope to get it right. It's not me, it's the process itself that
makes it work."
He went on to explain his best theory of why this
worked. On each iteration he was not
only adding details, but he was learning about each aspect of the bird in the
context of each decision he was making, as he was making it. He, like me, had spent his life absorbing all
these unspoken details about real birds in nature and, guided by this as the
photographs reminded him, and guided by each decision he had just made the
increment before, his current decisions were contextualized, and produced the
quality of nature that a good representation must have.
"I learned," he said, "quite by accident that
sculpting is not a process of planning and then executing the plan. Sculpting is a process of learning, of
unfolding. The piece emerges as a result
of a million little decisions, each made proximate to other decisions and, as
each decision is informed by the previous ones, it in turn informs the next
ones. Gradually a bird is born, complete
and organic and natural."
This is the process Alexander was describing, and in fact he
alluded to something that might have made it clear to me in the first place:
"The image of the differentiating process is the growth
of an embryo" he wrote.
We know, from the work of biologists, just how this
works. Termed "ontology" it starts with single, simple
cell, which then splits into two. These
two become four, then eight, then sixteen and so on, all the cells identical to
each other. It is not until enough of
the embryo exists, what biologists call the blastocyst, and we have what they
term "the context of the organism" that we begin to see the cells
differentiate and become the hearts and lungs and tendons and nerves, and the
creature emerges in full.
This is how nature does it, always. Nature knows what she is doing.
So now I understand that software design should be done this
same way. Not by starting with objects
and attempting, lego-style, to assemble them into a design, but rather by
starting with the problem... what is important to the customer, how they make
their money, what their risks and competitive pressures are, what the knowns
and unknowns are, and then to start small and simple, and allow my design to
emerge.
This is why design patterns work. This is why test-driven development works. This is why agile approaches are essential.
