Probably makes me laugh more than it ought to have

A parenthetical comment in a recent blog post from Ben Burgis:

Some friends of mine have this very nerdy running joke about starting a bar called "The Two Dogmas Of Alcoholism." We'd serve a shot called "The Analytic" and a shot called "The Synthetic" and both of them would be Jose Cuervo. When patrons had one of each and then asked what the difference was, the bar-tenders would all be trained to respond with, "ex-actly!"

I'd be a fan.

Opaque Introspection

Some time ago, Psyblog posted a series called "What Everyone Should Know About Their Own Minds". Appropriately enough, it covers different ways in which humans typically completely misunderstand (or misjudge) components of their own behavior such as motivations, reasons, and predictions about their own responses. Sometimes this involves resolving cognitive dissonance, where a subject changes some of her beliefs in order to better match other beliefs they had been opposing; other times the explanation is less clear.

The whole subject is a curious one, since, subjectively, most of us feel like we have pretty transparent access to the inside of our own heads. For example, if asked to give reasons why we find one face more attractive than another, we usually think we can do so so; and we feel moreover that the reasons we come up with will be true to whatever processes actually go on inside our heads. Not so, as one of the Psyblog posts reports; at least not with the accuracy that we'd think we would have.

My impression is that we are sometimes alien to our own minds, insofar as we don't understand most of our inner machinations. Yet, strangely, we have this need to "tell stories", even to ourselves, about why we've done things a particular way: a need for explanation or justification of our inner landscape, much in the fashion of the need that we have to explain (and understand) the outer world. This isn't such a bad thing, since seeking explanations is the heart of science (and rational inquiry). But it does emphasize the necessity of being relentlessly critical and skeptical if your aim is truth -- skeptical even about your own thought processes -- lest you settle too firmly on the first story that seems plausible to you.

A downside of the above skeptical strategy, in my own experience, is that it tends to drive you a little bit crazy. Constantly doubting your own motivations, values, judgments, and ostensible motivations is not a very enjoyable way to go about your day. After a certain point, if you lose too much faith in your own understanding with regard to the contents of your own head, you may end up impeding your own progress, due to constantly looking for nonexistent solid ground. From a practical "getting things done" standpoint, it may be better to be wrong about a few little details here and there if you're still able to function well in the main.

We may suppose, perhaps, that this was why we did not evolve to be more naturally self-critical and self-reflective creatures. Don't get me wrong, compared to any other form of intelligence that we know about, we still go pretty far toward it -- even the least reflective of individuals tries to purge logical inconsistencies from her thoughts, though the amount of tolerance for inconsistency obviously varies from person to person. But, based on experiments like those linked above, plausible-seeming beliefs about your own motivations were evolutionarily much more relevant to fitness than numerous safeguard mechanisms to ensure internal accuracy. Apparently.

Markram Speaks On Simulating the Brain

Henry Markram, director of the Blue Brain project, (relatively recently) gave a speech at TED about simulating neuron activity of the entire brain. This will require a supercomputer, in this case supplied by IBM, since the brain has some 10¹¹ neurons. So far, they've replicated a rat's neocortical column, which comprises some 10⁴ neurons, and Markram anticipates being able to fully model the human brain within 10 years.

One of the curious things that I found in the early part of his talk was how he kept saying "decisions" to refer to activity over which we have no direct control, such as the processing that goes into scaling object size based on distance. I'm not fond of that choice of words, since it seems to suggest that we, as conscious entities, could actually decide to perceive things differently from how we do -- something which should appeal to fans of neo-mystical idealism. For that reason, I think it would be better to avoid that kind of terminology to avoid a similar confusion as that which resulted from physicists' choice of the term "observe" to describe a particular type of interaction in quantum mechanics. They (physicists) also started the use of "God particle" to refer to the Higgs boson, which is again misleading to the general public, although I think the media has been more responsible for propagating that usage than any actual scientists.

Curious things, words.

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?

Science/Philosophy discussion on PF

Looks to be a very fascinating discussion about science and philosophy shaping up on the Philosophy Forums. At least, fascinating for my tastes, since I'm perennially interested in the question of what use philosophy really is these days compared to science.

Anyway, the thread starts out by directing several questions to John Searle (who is actually a member of the forums, although I suspect far too busy to be very active). Searle himself did give one response, but since then the thread's been drawing other participants; nonetheless, so far it has been a high caliber and well-reasoned discussion, by my estimation.

Here's a sample to whet your appetite, from the original poster (HamishMacSporran)'s response to Searle's own response:

... [M]any scientists take the view that the scientific revolution was made possible not by an accumulation of philosophical analysis, but instead by a rejection of the existing philosophical systems in favour of a new experimental method. From this point of view, scientists don't need philsophers [sic] to do their groundwork for them, but should instead ignore their clever arguments and focus on doing experiments. Hence the motto of the Royal Society, "Take nobody's word for it".

...

You [Searle] also raise the issue of computationalism within cognitive science, and your arguments against it. Whatever their merits, these arguments have not led to a conclusive rejection of computationalism. Dennett, for example, continues to deny your conclusions are valid, and the mind as a computer program metaphor continues to be common currency among cognitive scientists.

To many scientists this is just another symptom of philosophy's malaise: nothing ever gets resolved. That's why, instead of arguing for another thousand years about whether universals exist, they believe they need to focus on questions that can be definitively answered by experiment, with some even claiming that questions outside this domain are meaningless.

Does the computationalist hypothesis really have any experimental implications for cognitive scientists? What effects would you expect your arguments to have on a cognitive scientists research program? Are there benefits of philosophical dispute even in the case that no definite conclusion is reached?

Philosophy as counter-productive in a therapeutic sense?

From Irvin D. Yalom's Existential Psychotherapy:

As nature abhors a vacuum, we humans abhor uncertainty. One of the tasks of the therapist is to increase the patient's sense of certainty and mastery. It is a matter of no small importance that one be able to explain and order the events in our lives into some coherent and predictable pattern. To name something, to locate its place in a causal sequence, is to begin to experience it as under our control. No longer, then, is our internal experience or behavior frightening, alien or out of control; instead, we behave (or have a particular inner experience) because of something we can name or identify. The '"because" offers one mastery (or a sense of mastery that phenomenologically is tantamount to mastery). [pp. 189-190]

Does the study of philosophy, I wonder, run counter to that need we have for certainty? Or on the contrary, does it perhaps assist it? After all, though philosophy does not provide us with cut-and-dry answers, and its study exacerbates our awareness of the human's dismal epistemic and existential plight, nonetheless any sort of rational investigation (of which philosophy purports to be the discipline par excellance) will invariably encompass the latter part of Yalom's quote, viz., the bit about "naming" and explaining/ordering events.

The Ancients make for a good example here: reducing the physical world's phenomena to a limited number of substances--e.g. fire/change for Heraclitus, water for Thales, air for Anaximenes, all four elements for Empedocles--allows the more succinct and manageable comprehension of that world. Rational reductionism of all shades and hues affords a better sense of psychological certainty, and consequently an increased feeling of "mastery". Science, as the eventual granddaughter of this impulse, performs the same function, although our methods have since grown much more mathematical and empirical.

But by no means ought we think this strategy unique to science and philosophy. Human mythology is cross-culturally rife with proposed explanations for phenomena ("just so" stories). Tellingly, many of them explicitly exalt the importance of words and naming in the development of humanity. For current Euro-American culture, most obviously we see Adam's naming of the beasts in Genesis. Sigmund Freud asserted that religion attempts to reconcile our needs for control against the volatile chaos of nature: if the natural world is controlled utterly by a superior being who acts as a father for us, we are thus assured that there is order lurking behind ostensible chaos; and, more importantly, it is an order with our own best interests in mind (eventually, that is. Because God's will is inscrutable and ineffable, we must accept that bad things will happen to us in the now). Finally, it is an order which is not set forever in stone, but an order which may be bargained with and appealed to, since it is ruled fundamentally by a person of sorts, not by a blind, unintelligent, and uncaring force. (The "Communication/Negotiation" section of my post "The Immutability of Vicissitudes, Part 1" addresses this too.)

It may in fact be fruitful to analyze the scientific thirst for knowledge in light of psychoanalytical need for control, and I am positive that I'm not the first to suggest this. We might say that science-lust is an extension of Freud's interpretation of religion: science serves similar psychological needs, although it requires a deep paradigm shift as well. The scientific Weltanschauung does not privilege humanity by pretending that the universe operates in humanity's best interest, nor does it offer us a kindly father-figure. However, it does give us an explanation--an understanding of order inherent behind the horrible confusions nature presents us with; and it supplies us, through understanding, with a means to combat our own helplessness.

Thus, science may be seen nearly as an outgrowth of religion (more properly, the religious impulse); but it is one that replaces an anthropomorphic epistemology with a mechanical epistemology. As Quine said of physical objects and gods,

Both sorts of entities enter our conception only as cultural posits. The myth of physical objects is epistemologically superior to most in that it has proved more efficacious than other myths as a device for working a manageable structure into the flux of experience. ["Two Dogmas of Empiricism"]

That is to say, we put forth the common understanding of physical objects (as opposed to the skeptic's or the idealist's) as an explanation for our collected observations in the same way that, and for similar reasons as, our ancestors put forth gods. However, gods are not very good explanations and they do not enable us to do things the way that believing in the reality of physical objects do; hence their (physical objects') epistemic superiority.

Though we cannot appeal to a God anymore, science does furnish us with a means to control nature ourselves, which is something that religion and mythology could never adequately supply. From this we get the term "playing God" and our species' tradition of shunning technological progress for the power it takes away from God. Now, the contemporary existentially-minded human finds herself sitting down in God's throne after having killed Him, and she finds herself terrified by the loneliness, the lack of direction, and the growing awareness that, if God had ever existed, He wouldn't have been any better off than she is now.

So, all respect due to Boethius, is philosophy actually a consolation? Cautiously, I say that it can be; but I hasten to add that stopping there is woefully (and willfully?) near-sighted. Rational inquiry enables us to satisfy some of the needs Yalom detailed above in a similar capacity that religion has served past-ly. Unfortunately, we no sooner find a good reason to believe something than we recognize that there can be no absolute certainty (in a broad sense). Naming (and, these days, quantifying) the surrounding world is a valuable ability, but the relentless and open-eyed pursuit of exhaustive naming schemes leads one to the conclusion that such things are impossible--and that certainty is more so.

(It seems to me that Mark Z. Danielewski deals with these themes among others in his novel House of Leaves, although I may not be able to say exactly how.)

Link Dump

So here are some blog entries (or whatever) I have recently found interesting.

At Theoretical Atlas, Jeffrey Morton recounts a talk given by Gregory Chaitin where Chaitin urges us to create a more rigorous "theoretical biology". Something where we could prove interesting theorems about evolutionary models, for example.

At (Blog&~Blog), Ben Burgis writes a bit about Graham Priest's Sylvan's Box story and the (im)plausibility of drawing conclusions about "real life" logic from the logic that exists in fiction.

Alan Rhoda discusses the Law of Excluded Middle in the context of propositions about the future, responding to an example supplied by David Hunt.

This is a somewhat older paper (1997) by Allen F. Randall entitled "Quantum Phenomenology". He attempts something of an updated version of Descartes' cogito (maybe mixed with Kant's transcendental project), attempting to logically derive the principles of quantum mechanics from the basic awareness of experiential existence (my phrase, not Randall's). Randall claims, "Far from being "bizarre" and "weird", as is usually thought, the strangest paradoxes of quantum theory turn out to be just what one ought to expect of a rational universe." I admit, I've only read the first part of this paper, but it's still a very fascinating idea.

At Mixing Memory, Chris reports on several studies where unpleasant stimuli (such as foul odors, messy/sloppy workspaces, disgusting video footage) harshen the severity of people's moral judgments.
