Thinking vs Acting

I still don't understand exactly the "internal" difference between doing and just..... thinking about doing. Imagining it.


If I now intend to make a physical action, such as wiggle one of my toes, there's something happening in my mind that precedes that action--an anticipatory "planning" or intention stage. (If I remember correctly, studies by Benjamin Libet suggest that we don't even become conscious of our brain's decision to initiate an action until some 200-500ms after our brain starts setting it in motion.) But I can think about wiggling a toe without actually doing it--in fact, that's what I'm doing now as I make these observations, and what you the reader will likely be doing as these words call forth involuntary recollections in your mind. I can imagine wiggling a toe, even. Since most of us are such visual creatures, this will probably be first and foremost a mentally created image of my own toe wiggling (somehow); as I add detail to the imagining, I can recall the other sensations that accompany such a feat: the quale of my toe shifting position, the accompanying movement of my skin, the small shifts in texture or whatever that my skin will register if my movement causes it to encounter new surfaces/objects, etc.

I can even try to mentally re-create (simulate) the very willing, or whatever it is, that causes genuine movement. I can do this at a somewhat intuitive level, I think, but I feel I have a very poor grasp on what is actually happening.

Now, the curious thing about my imaginings here, is that imagining itself is another type of action; so, while I'm tinkering with how my mind translates thought into action, I am meanwhile doing just that in order to "experiment" at all. (Proper scientists will be horrified to here such phenomenological investigation referred to as "experimentation", but hey, I'm not talking about proper scientific experiments in this context.)

It seems that there is always some kind of buffer or gap that I cannot quite cross here.

Inquiry Into Impossibility

(Briefly).

I am a being with desires. Roughly, this means that I, as a sentient system, feel impelled to relieve an urge. So, I create a mental simulation of some thing, some state of affairs that differs from the current state of the world, that I expect (or hope) will alleviate that urge.
A simple example: Debra is hungry. Instinct and memory tell her that moving her body so as to bring comestibles to her mouth and chew (+ swallow, etc.) will make her less hungry. Thus, her object of desire is a state where she has eaten food, or where her stomach is full, or something to that effect.
The fundamental principle, as everyone already knows, is that actions modify our environment, and our bodies consequently reward us – with dopamine and the diminishment of urge – through modifying the environment in particular ways.

What happens, now, if I desire something impossible?

Let me sit and contemplate a bowl of fruit. My desire is for one of the fruit – a mango, perhaps – to be in my hand. I have, then, a clearly defined goal (a simulated aspect of the environment which will sate my want), and all that remains is to use the power of action to translate object of desire into actuality. Common sense says I should move myself within range of the bowl (if I'm not there already), extend an arm, and pick it up. However, my desire is slightly more complex than that: I want to achieve my goal without going through those steps. Part of my envisioned goal includes the condition that I collect the mango in the absence of gross physical movement.
There might be other options: maybe I have a friend (or servant) nearby who will interpret a very slight gesture on my part as a request for the mango. Or maybe there's a mechanical hand and conveyor belt set up that leads directly to my own biological hand, and it is activated through some minute action – moving my eyes or blinking in a particular pattern, for example.
But let's say none of these things have been arranged: the most likely situation is that I'm sitting in place alone, unaided, merely willing the mango to somehow appear in my hand through no great effort of my own.
That this should happen is improbable to the point of impossibility.
So, I review my options: supposing that I stubbornly stick to my original constraints (no gross physical movement), there is little to nothing that I can do to change the situation. To effect change, action is required; and only a particular subset of available actions leads to particular (desired) outcomes. If the set of actions-available-to-me happens to be disjoint to the set of actions-leading-to-my-goal, it seems I am utterly powerless. There must be overlap between those categories, otherwise it is logically impossible for me to achieve my goal through action.
Is there any other way to achieve a goal than through action? By the very nature of the word "achieve", I think the answer is no. Is it possible for me to accomplish something while doing nothing? Pace Laozi, the very idea reeks of contradiction. "But," I protest, "I am doing something – I'm thinking and simulating." The problem is that, apparently, thinking and simulating exert no influence on the universe if they are not accompanied by physical forces to realize their aims. Alone, they do not overlap with very many sets of actions-that-lead-to-goals at all.

How can I shape the universe to match my desires? Only through the channels that the universe allows me. And so the question becomes, how can I change those channels?

Controlling oneself

Fascinating post over at Less Wrong about the influence of control systems on human behavior, and the role they seem to play in the brain. A control system here basically means a feedback device that catalyzes or inhibits some variable in order to maintain it within an accepted range. (Thermostat, homeostasis, etc.)


Here's a lengthy quote that seems most pertinent to me:
In a primitive, tribal culture, being seen as useless to the tribe could easily be a death sentence, so we [likely] evolved mechanisms to avoid giving the impression of being useless. A good way to avoid showing your incompetence is to simply not do the things you're incompetent at, or things which you suspect you might be incompetent at and that have a great associated cost for failure. If it's important for your image within the tribe that you do not fail at something, then you attempt to avoid doing that.

You might already be seeing where this is leading. The things many of us procrastinate on are exactly the kinds of things that are important to us. We're deathly afraid of the consequences of what might happen if we fail at them, so there are powerful forces in play trying to make us not work on them at all. Unfortunately, for beings living in modern society, this behavior is maladaptive and buggy. It leads to us having control circuits which try to keep us unproductive, and when they pick up on things that might make us more productive, they start suppressing our use of those techniques.

Furthermore, the control circuits are stupid. They are occasionally capable of being somewhat predictive, but they are fundamentally just doing some simple pattern-matching, oblivious to deeper subtleties. They may end up reacting to wholly wrong inputs. Consider the example of developing a phobia for a particular place, or a particular kind of environment. Something very bad happens to you in that place once, and as a result, a circuit is formed in your brain that's designed to keep you out of such situations in the future. Whenever it detects that you are in a place resembling the one where the incident happened, it starts sending error signals to get you away from there. Only that this is a very crude and unoptimal way of keeping you out of trouble - if a car hit you while you were crossing the road, you might develop a phobia for crossing the road. Needless to say, this is more trouble than it's worth.
(P.S., I should note that the author of the quoted blog post, Kaj_Sotala, draws this conceptual material largely from a self-help article by PJ Eby).

Fascinating stuff. Maybe not without its problems though, as commenter Silas Barta notes:
The explanations here for behavioral phenomena look like commonsense reasoning that is being shoehorned into controls terminology by clever relabeling. (ETA: Why do you need the concept of a "feedback control system" to think of the idea of running through the reasons you're afraid of something, for example?)
The thought concerns me a bit too. Are we really getting any benefit from describing these aspects of behavior as control mechanisms? Are we getting a more accurate model of behavior? At an individual, practical level, does it help us to conceive of our thought processes in this way?

Want? Choice?

Why is it so hard to be a particular way by choice?

Why is it that I cannot simply decide one day, hey, I want to accomplish X--and then pursue it?

Nothing prevents me.

Akrasia...?

Cats and the Qualia of Happiness

My cat, having satisfied himself with the food available indoors, ambles back to the door and sits expectantly. He'll look up at the portal, look around, look at me occasionally. If I draw close, he'll rise up and paw the side of the door, possibly rub himself against me, make movements that seem to express a readiness to go forth. He meows on occasion, if the exit remains barred for too long.

As near as I can tell, he experiences a desire to go outside.

Would he feel pleasure from his desire being fulfilled, or would he simply feel relief from the pressing urge?

And sometimes...

[And sometimes, perhaps, desires can be trusted. Or, miraculously and all the more mysteriously, they can shape.]

I wonder then, were perfection nearly within grasp, how terrifying might that be? And too, how exhilarating, giddying! For Tantalus's hand to brush the grapes, his lips to graze the waters.

Imagine the moment following this unprecedented anomaly: his pulse races, a hitherto dulled and pessimistic mind comes alight, afire! Certainty (and its incumbent predictability) had blunted and wearied his existence. For surely Tantalus had realized – real-ized! – the despotic futility that ruled and overruled his every action, that denied him possibility of relief. Surely, he at last reached a point where unrelenting failure wore away the last of his persistence, leaving him stupefied, resigned, and stultified.

Imagine the moment prior: the cusp of despair, his head bows, and he begs penitently to the gods, as he has done countless times before. He knows well the gesture's uselessness: they will not heed him--and is it that they do not hear or do not care? Or is there anyone to hear? So long has been his imprisonment, that who can say which beings existed, or did fancy alone conjure up his divine imprisoners? Did he really host that profane and awful banquet? Or did he imagine his feat of hubris merely as to justify his own torment? But watch now, as his head bows, his parched and broken lips touch for one instant the inconceivable--the impossible, the unreal--and shatter his dreadful certainty.

How this moisture? How this incomprehensible moisture, there long enough to shock yet gone before it can be tasted? What does it mean, what can it mean? That the gods have heard, relented? Or their powers wane and may now be circumvented?

Imagine his reckless rejuvenation as thoughts careen throughout his jolted mind. An intoxicating force invigorates his ailing hopes and catapults him beyond Reason; and with that same resurgence comes a creeping, dawning horror: he is poised now at the brink of lunatic conclusions, and if he stretches just a little further, will his lips find long-sought respite? Or will the conscious act of striving revoke his supposed progress and rebuke him all the more?

Be this redemption, or a god's mocking laughter?

Is it chance that furnishes him with hope, or insidious design?

Is this opportunity, or is it a desire's wishful mirage? Is there any action he can possibly take to sway the outcome either way? If he chooses wrongly, will he ever get this chance again? And so horrible, if not, to live on knowing that he'd once come so near perfection, but failed and damned himself.

.. to desire a thing so much that one is paralyzed by the very possibility of it being unattainable...
