Lawful Creativity

Previously in SeriesRecognizing Intelligence

Creativity, we've all been told, is about Jumping Out Of The System, as Hofstadter calls it (JOOTSing for short).  Questioned assumptions, violated expectations.

Fire is dangerous: the rule of fire is to run away from it.  What must have gone through the mind of the first hominid to domesticate fire?  The rule of milk is that it spoils quickly and then you can't drink it - who first turned milk into cheese?  The rule of computers is that they're made with vacuum tubes, fill a room and are so expensive that only corporations can own them.  Wasn't the transistor a surprise...

Who, then, could put laws on creativity?  Who could bound it, who could circumscribe it, even with a concept boundary that distinguishes "creativity" from "not creativity"?  No matter what system you try to lay down, mightn't a more clever person JOOTS right out of it?  If you say "This, this, and this is 'creative'" aren't you just making up the sort of rule that creative minds love to violate?

Why, look at all the rules that smart people have violated throughout history, to the enormous profit of humanity.  Indeed, the most amazing acts of creativity are those that violate the rules that we would least expect to be violated.

Is there not even creativity on the level of how to think?  Wasn't the invention of Science a creative act that violated old beliefs about rationality?  Who, then, can lay down a law of creativity?

But there is one law of creativity which cannot be violated...

Mundane Magic

Followup toJoy in the Merely Real, Joy in Discovery, If You Demand Magic, Magic Won't Help

As you may recall from some months earlier, I think that part of the rationalist ethos is binding yourself emotionally to an absolutely lawful reductionistic universe - a universe containing no ontologically basic mental things such as souls or magic - and pouring all your hope and all your care into that merely real universe and its possibilities, without disappointment.

There's an old trick for combating dukkha where you make a list of things you're grateful for, like a roof over your head.

So why not make a list of abilities you have that would be amazingly cool if they were magic, or if only a few chosen individuals had them?

For example, suppose that instead of one eye, you possessed a magical second eye embedded in your forehead.  And this second eye enabled you to see into the third dimension - so that you could somehow tell how far away things were - where an ordinary eye would see only a two-dimensional shadow of the true world.  Only the possessors of this ability can accurately aim the legendary distance-weapons that kill at ranges far beyond a sword, or use to their fullest potential the shells of ultrafast machinery called "cars".

"Binocular vision" would be too light a term for this ability.  We'll only appreciate it once it has a properly impressive name, like Mystic Eyes of Depth Perception.

So here's a list of some of my favorite magical powers:

Entangled Truths, Contagious Lies

"One of your very early philosophers came to the conclusion that a fully competent mind, from a study of one fact or artifact belonging to any given universe, could construct or visualize that universe, from the instant of its creation to its ultimate end..."
        -- First Lensman

"If any one of you will concentrate upon one single fact, or small object, such as a pebble or the seed of a plant or other creature, for as short a period of time as one hundred of your years, you will begin to perceive its truth."
        -- Gray Lensman

I am reasonably sure that a single pebble, taken from a beach of our own Earth, does not specify the continents and countries, politics and people of this Earth.  Other planets in space and time, other Everett branches, would generate the same pebble.  On the other hand, the identity of a single pebble would seem to include our laws of physics.  In that sense the entirety of our Universe - all the Everett branches - would be implied by the pebble.  (If, as seems likely, there are no truly free variables.)

So a single pebble probably does not imply our whole Earth.  But a single pebble implies a very great deal.  From the study of that single pebble you could see the laws of physics and all they imply.  Thinking about those laws of physics, you can see that planets will form, and you can guess that the pebble came from such a planet.  The internal crystals and molecular formations of the pebble formed under gravity, which tells you something about the planet's mass; the mix of elements in the pebble tells you something about the planet's formation.

I am not a geologist, so I don't know to which mysteries geologists are privy.  But I find it very easy to imagine showing a geologist a pebble, and saying, "This pebble came from a beach at Half Moon Bay", and the geologist immediately says, "I'm confused" or even "You liar".  Maybe it's the wrong kind of rock, or the pebble isn't worn enough to be from a beach - I don't know pebbles well enough to guess the linkages and signatures by which I might be caught, which is the point.

Beyond the Reach of God

Followup toThe Magnitude of His Own Folly

Today's post is a tad gloomier than usual, as I measure such things.  It deals with a thought experiment I invented to smash my own optimism, after I realized that optimism had misled me.  Those readers sympathetic to arguments like, "It's important to keep our biases because they help us stay happy," should consider not reading.  (Unless they have something to protect, including their own life.)

So!  Looking back on the magnitude of my own folly, I realized that at the root of it had been a disbelief in the Future's vulnerability - a reluctance to accept that things could really turn out wrong.  Not as the result of any explicit propositional verbal belief.  More like something inside that persisted in believing, even in the face of adversity, that everything would be all right in the end.

Some would account this a virtue (zettai daijobu da yo), and others would say that it's a thing necessary for mental health.

But we don't live in that world.  We live in the world beyond the reach of God.

My Naturalistic Awakening

Followup toFighting a Rearguard Action Against the Truth

In yesterday's episode, Eliezer2001 is fighting a rearguard action against the truth.  Only gradually shifting his beliefs, admitting an increasing probability in a different scenario, but never saying outright, "I was wrong before."  He repairs his strategies as they are challenged, finding new justifications for just the same plan he pursued before.

(Of which it is therefore said:  "Beware lest you fight a rearguard retreat against the evidence, grudgingly conceding each foot of ground only when forced, feeling cheated.  Surrender to the truth as quickly as you can.  Do this the instant you realize what you are resisting; the instant you can see from which quarter the winds of evidence are blowing against you.")

Memory fades, and I can hardly bear to look back upon those times - no, seriously, I can't stand reading my old writing.  I've already been corrected once in my recollections, by those who were present.  And so, though I remember the important events, I'm not really sure what order they happened in, let alone what year.

But if I had to pick a moment when my folly broke, I would pick the moment when I first comprehended, in full generality, the notion of an optimization process.  That was the point at which I first looked back and said, "I've been a fool."

The Sheer Folly of Callow Youth

Followup toMy Childhood Death Spiral, My Best and Worst Mistake, A Prodigy of Refutation

"There speaks the sheer folly of callow youth; the rashness of an ignorance so abysmal as to be possible only to one of your ephemeral race..."
        -- Gharlane of Eddore

Once upon a time, years ago, I propounded a mysterious answer to a mysterious question - as I've hinted on several occasions.  The mysterious question to which I propounded a mysterious answer was not, however, consciousness - or rather, not only consciousness.  No, the more embarrassing error was that I took a mysterious view of morality.

I held off on discussing that until now, after the series on metaethics, because I wanted it to be clear that Eliezer1997 had gotten it wrong.

When we last left off, Eliezer1997, not satisfied with arguing in an intuitive sense that superintelligence would be moral, was setting out to argue inescapably that creating superintelligence was the right thing to do.

Well (said Eliezer1997) let's begin by asking the question:  Does life have, in fact, any meaning?

Psychic Powers

Followup to: Excluding the Supernatural

Yesterday, I wrote:

If the "boring view" of reality is correct, then you can never predict anything irreducible because you are reducible.  You can never get Bayesian confirmation for a hypothesis of irreducibility, because any prediction you can make is, therefore, something that could also be predicted by a reducible thing, namely your brain.

Benja Fallenstein commented:

I think that while you can in this case never devise an empirical test whose outcome could logically prove irreducibility, there is no clear reason to believe that you cannot devise a test whose counterfactual outcome in an irreducible world would make irreducibility subjectively much more probable (given an Occamian prior).

Without getting into reducibility/irreducibility, consider the scenario that the physical universe makes it possible to build a hypercomputer -- that performs operations on arbitrary real numbers, for example -- but that our brains do not actually make use of this: they can be simulated perfectly well by an ordinary Turing machine, thank you very much...

Well, that's a very intelligent argument, Benja Fallenstein.  But I have a crushing reply to your argument, such that, once I deliver it, you will at once give up further debate with me on this particular point:

Excluding the Supernatural

Followup toReductionism, Anthropomorphic Optimism

Occasionally, you hear someone claiming that creationism should not be taught in schools, especially not as a competing hypothesis to evolution, because creationism is a priori and automatically excluded from scientific consideration, in that it invokes the "supernatural".

So... is the idea here, that creationism could be true, but even if it were true, you wouldn't be allowed to teach it in science class, because science is only about "natural" things?

It seems clear enough that this notion stems from the desire to avoid a confrontation between science and religion.  You don't want to come right out and say that science doesn't teach Religious Claim X because X has been tested by the scientific method and found false.  So instead, you can... um... claim that science is excluding hypothesis X a priori.  That way you don't have to discuss how experiment has falsified X a posteriori.

Of course this plays right into the creationist claim that Intelligent Design isn't getting a fair shake from science - that science has prejudged the issue in favor of atheism, regardless of the evidence.  If science excluded Intelligent Design a priori, this would be a justified complaint!

But let's back up a moment.  The one comes to you and says:  "Intelligent Design is excluded from being science a priori, because it is 'supernatural', and science only deals in 'natural' explanations."

What exactly do they mean, "supernatural"?  Is any explanation invented by someone with the last name "Cohen" a supernatural one?  If we're going to summarily kick a set of hypotheses out of science, what is it that we're supposed to exclude?

By far the best definition I've ever heard of the supernatural is Richard Carrier's:  A "supernatural" explanation appeals to ontologically basic mental things, mental entities that cannot be reduced to nonmental entities.

Abstracted Idealized Dynamics

Followup toMorality as Fixed Computation

I keep trying to describe morality as a "computation", but people don't stand up and say "Aha!"

Pondering the surprising inferential distances that seem to be at work here, it occurs to me that when I say "computation", some of my listeners may not hear the Word of Power that I thought I was emitting; but, rather, may think of some complicated boring unimportant thing like Microsoft Word.

Maybe I should have said that morality is an abstracted idealized dynamic.  This might not have meant anything to start with, but at least it wouldn't sound like I was describing Microsoft Word.

How, oh how, am I to describe the awesome import of this concept, "computation"?

Perhaps I can display the inner nature of computation, in its most general form, by showing how that inner nature manifests in something that seems very unlike Microsoft Word - namely, morality.

Consider certain features we might wish to ascribe to that-which-we-call "morality", or "should" or "right" or "good":

• It seems that we sometimes think about morality in our armchairs, without further peeking at the state of the outside world, and arrive at some previously unknown conclusion.

Someone sees a slave being whipped, and it doesn't occur to them right away that slavery is wrong.  But they go home and think about it, and imagine themselves in the slave's place, and finally think, "No."

Can you think of anywhere else that something like this happens?

Inseparably Right; or, Joy in the Merely Good

Followup toThe Meaning of Right

I fear that in my drive for full explanation, I may have obscured the punchline from my theory of metaethics.  Here then is an attempted rephrase:

There is no pure ghostly essence of goodness apart from things like truth, happiness and sentient life.

What do you value?  At a guess, you value the life of your friends and your family and your Significant Other and yourself, all in different ways.  You would probably say that you value human life in general, and I would take your word for it, though Robin Hanson might ask how you've acted on this supposed preference.  If you're reading this blog you probably attach some value to truth for the sake of truth.  If you've ever learned to play a musical instrument, or paint a picture, or if you've ever solved a math problem for the fun of it, then you probably attach real value to good art.  You value your freedom, the control that you possess over your own life; and if you've ever really helped someone you probably enjoyed it.  You might not think of playing a video game as a great sacrifice of dutiful morality, but I for one would not wish to see the joy of complex challenge perish from the universe.  You may not think of telling jokes as a matter of interpersonal morality, but I would consider the human sense of humor as part of the gift we give to tomorrow.

And you value many more things than these.

Your brain assesses these things I have said, or others, or more, depending on the specific event, and finally affixes a little internal representational label that we recognize and call "good".

There's no way you can detach the little label from what it stands for, and still make ontological or moral sense.
