What Everyone Ought to Know about Stoic Thought on the Emotions
If you say someone is stoic, you’re almost certainly giving them a compliment, specifically that they stood strong in the face of a very bad situation. And with that sort of good PR, its probably not a surprise that Stoicism is a very popular search term on Google. In fact, ‘Stoicism’ gets 56% more hits than ‘Platonism’ and 469% more hits than ‘Aristotelianism’. Now, a lot of this is likely due to the facts that people usually search for ‘Plato’ instead of ‘Platonism’ and ‘Aristotle’ instead of ‘Aristotelianism’ and relatively few people know that Zeno of Citium founded Stoicism or even that its most well known exponent was Epictetus.
Still, the fact is that Zeno and Epictetus created and spread a philosophy that is quite famous and well respected even to the present day. That certainly deserves a lot of respect. And I highly recommend anyone interested in how ethical philosophy influenced modern religions study the Stoics. I can't think of a philosophy closer to Christianity than Stoicism.

| Marcus Aurelius With all that said, let me go a head and put it on the table that I’m going to be highly critical of the stoic view of the emotions. But before that, a little more background. Zeno the Stoic, a near contemporary of Epicurus (341 B.C.), was born in 334 B.C. 13 years after the death of Plato (347 B.C.) and about 20 years before Aristotle died (322 B.C.). Zeno probably never met Aristotle but almost certainly knew Epicurus very well. In fact, many people think Zeno set up his school specifically as a counter to Epicurus’ school. Be that as it may, the sad thing is all of Zeno’s writings are lost. As a result, we typically turn to the Roman stoics to study Stoicism. (No doubt that its huge importance in Epictetus - The spokesman for Stoicism It is not very controversial to say that the most compelling, most well regarded source of Stoicism we have is the works of Epictetus. Not only was he a very clear writer and consistent thinker, but his life story is also quite compelling. Unlike so many of the great philosophers before him, Epictetus was not a wealthy man. In fact, he was born and raised a slave, and suffered from a permanent physical disability that left him with a pronounced limp. However unfortunate you judge those limitations to be, he had the relative benefit of being the slave of a very important Roman administrator and thus received an excellent education, focused squarely on Stoic philosophy. And he did eventually gain his freedom. The fundamental Stoic beliefs regarding the emotions The Stoic philosophy of emotion builds on three fundamental claims. The first, absolute bedrock idea is that Emotions are identical with judgments The other two fundamental beliefs are that Emotions are voluntary And that Emotions should be eliminated Just to be clear, what they believe is that like when you feel happy or sad, it is exactly the same sort of mental process as when you decide someone is boring or that you would prefer cheeseburgers to doughnuts. And that these choices, the decisive opinions, are completely up to you and no one else. No one can make you prefer cheeseburgers and no on can make you angry. Only you can decide. Finally, you should not have any emotions. You probably noticed that that last bit doesn’t exactly follow logically. I mean, just because of the fact that emotions are choices that you make and that only you can make, it doesn’t mean that you shouldn’t have them. After all, they certainly don’t think you should have no judgments at all! So to understand the Stoics on the emotions we need to understand why emotions are not the kind of judgments you should have. According to the great Cicero, a very famous Roman statesman, philosopher and legal scholar and in my opinion one of the 2-3 most brilliant Ancient Romans, who was often but not always an advocate of stoic teachings, the Stoics “refuse to concede that a person ought to have any feelings at all”. And he’s right, the Stoic position on emotions is quite simply that they are bad and must be completely excluded from life if a person ever wants to be good and happy. As you may have already figured out, I find this conclusion completely misguided, and easily the least satisfactory account of the emotions in the ancient world. I’ll argue that the Stoic philosophy of emotions was guilty of egregious errors that, due to Stoicism’s pervasive influence for subsequent thinkers, have done an extraordinary amount of damage to our understanding of the emotions and so to our ethical thinking. More specifically, I’m going to show you how Stoicism was the starting point for the fundamental flaws present in what today we’d call “cognitive” theories of emotion and motivated the fundamental flaws present in what today we’d call “physicalist” (I call them visceral) theories of emotion. Next week I'll begin laying out Epictetus' "handbook for Stoicism", the Enchiridion |

How to Understand The Epicureans on Emotion, Part II of II
That's certainly a tough lesson for many to learn, but it has the ring of truth to it, and, at least in my case, experience says it's often true. Perhaps you're one of the lucky ones who think all this is rather obvious and that there's not much to see here. Either way, lets look a little deeper because there's plenty more to see.
Do we really ALWAYS act to avoid pain and fear / to get pleasure?
Taking the claim that we always act to seek pleasure / avoid pain at face value may seem at times brilliantly simply and at other times a cliché or an uninformative tautology.
Consider the following:
1. Pleasure is the avoidance of pain
2. All action is to avoid pain
3. If its true that when our desires are eliminated, we do not act, then when we eliminate pain, we do not act until there is another possibility of removing pain.
That is, it appears what we're agreeing to is that when we succeed in eliminating pain, we cease to have desires, and so we cease to have any reason to act, so we don't act.
Does that have the ring of truth or sound like a tautology? Hardly. Its actually a strange thing to consider. I mean, I can imagine you could argue that someone in a drunk stupor, high on drugs, having just achieved orgasm or having completed a delicious meal could be 'sated' in such a way as to have no desire to do anything.
For a time. Specifically, until some other 'pain' interferes with our state of repose. But then all we really seem to have learned is that we'll always be hungry and that the effort to satisfy certain hungers will pay off longer or better than others. But Plato and Aristotle already made that very clear.
So what in the world are we really saying in agreeing with the 'obvious' truths that pleasure is the absence of pain and all action is to avoid pain?
What's really happening here?
Ask yourself this - what actually happens when you, by luck or by careful planning, act in a way that truly maximizes your pleasure?
The first thing that occurs to me in asking myself that is that in such cases its highly likely that it involved a lot more than a stroke of luck, my brain - more or less consciously - was deeply involved. And the more such 'maximized pleasure' moments one has, the more likely it is that more than just luck was involved.
So the first thing I'd feel good about concluding is that some of the times that I really maximize my pleasure require a bit of thought. But I also have to accept that other times its more the case that I fell back on some training - which may have required thought in the past, but little now.
For example, the goal of having a tasty snack is a simple, good goal. It doesn't require a whole lot of thinking. But in fulfilling it you do have to have the implicit awareness that not everything that looks tasty is tasty.
So when reaching into the cookie jar for some Oreos, you might recall the time you accidentally got some nasty off-brand cookie and so double check what you pulled out this time. That would be 'goal awareness' plus 'realizing' or 'knowing' that looks can be deceiving.
The epicurean maxims we've been discussing can handle this. And actually, thats nice - in a way they are saying we can judge without deliberating. That's a good thing, and its in agreement with P-A-L. But there's going to be a few problems.
Let's quickly note that Plato, Aristotle, Lucretius and Epicurus all basically agree on some key points:
1. Every action is done for the sake of getting to some ultimate end. Depending on who you ask, that the ultimate goal could be said to be accumulating wealth, political power, sexual conquests, or perhaps a life of the mind.
2. But as far as the philosophers I noted above, they're all pretty much in agreement that the ultimate end isn't really any one of those things but rather happiness. A major caveat - each one of the philosophers mentioned has subtle and interesting differences in just what happinessis.
3. They do, however, stand in agreement that achieving happiness is mostly up to us and requires us to be virtuous. But that means that they also agree that being happy requires some level of control over our desires.
The issue, as I tried to make plain at the beginning of this project, is that its going to take a solid understanding of human psychology to determine what makes humans happy in general, and what will make you happy.
Not a rhetorical question: Just how far does 'all action is for the avoidance of pain' go in that direction?
Identifying the Problems Epicureanism has with Emotion
Epicurus strikes out from this basic agreement with P-A-L do to his thoughts on how to deal with the fact that we sometimes choose to act in ways that do not give us what we seek, pleasure, but instead give us the opposite.
Epicurus thinks that when we act so that we end up in real pain, its caused by both chosen/conscious actions and by reflexive actions,including emotion-driven actions, even though we never intend for this to happen.
Remember, we always seek pleasure, we always act to get pleasure. When the emotions sometimes lead you to pain, they make you wrong about the outcome your actions will lead to.
That is, emotions cause you to think improperly, to be mistaken about the facts of the matter, and so to incorrectly choose what will bring you pleasure. Not only that, acting emotionally is sometimes choosing to act in ways that do not give us what we seek, but instead give us the opposite.
As such, emotions need to be eliminated. They're just too dangerous. And they, on the surface at least, contradict a major Epicurean tenet - that we always act to pursue pleasure.
Rhetorical question: Is happiness an emotion or isn't it?
Let's be clear - Epicurus thinks that when we fail to achieve pleasure, we chose to act for pleasure but were wrong about what we thought we'd achieve. After all, we to some extent always chose to act. Similarly, Epicurus also believes that even more or less unchosen acts that lead to real pain (not pleasure-creating pains) are the opposite of what we 'wanted' to achieve.
That is, whether or not we are acting in 'full choice', or acting 'instinctively' or 'reflexively', act that induce real pain are errors. And we definitely want to be conscious of what motivates our chosen actions, as this will help avoid future errors. So he counsels that we hone our abilities to control 'instinctual' or 'reflexive' acts taken to avoid pain.
But are we ever going to consistently get what we want - no pain or fear - by listening to Epicurus' advice that only the proper pursuit of necessary desires will ensure our desires are truly fulfilled? That is, can we and should we act exclusively and correctly for the repose of the mind and body and nothing more? That's certainly the prescription.He encapsulates all this when he says “the pleasant life comes from searching out the motives for all choice and avoidance, and banishing mere opinions (like many emotions), to which are due the greatest disturbances of the spirit”.
Conclusion
Alright, I've been slow-playing my criticisms of Epicurus' take on the emotions and how they influence his moral philosophy but its time to play my hand.
The emotions are real trouble for Epicurus' theory for the simple reason that a person's success at understanding and controlling the emotions will determine how good an epicurean she will be.
Epicurus agrees with Plato and Aristotle that in some situations, certain emotions will prove exceedingly difficult to avoid. At its core Epicureanism is advising us that only a small subset of our desires - the natural and necessary - is at all necessary for and conducive to happiness. That's why Epicurus insists we understand the types of desires. Knowing what's what will allow you to act in a way so as to have and maintain a healthy body and a mind free of disturbance. And because of the fact unmodulated or ungoverned emotions can work powerfully against this goal, he wants to throw the baby out with the bathwater and eliminate emotions.
The problem for Epicureanism as a guiding moral philosophy, what leads it to this conclusion, stems from the fact that for most people who might try to be epicureans precious little of what we do is a result of conscious deliberation. And thus to make it work we're going to have to find some way to train ourselves to act appropriately in cases where we're not consciously considering the true nature of the desire we're dealing with. But how is this training supposed to work? How do you raise a child this way and how do you reverse-engineer it in a mature adult?
I'll remind you one last time that according to Epicureanism, young or old, educated or ignorant, we always act to achieve happiness or pleasure, to avoid pain or fear. But just what does that mean when we in fact do not often consciously think about our actions and what is really motivating our desires?
It means that we often get tricked. It means that in order for most of us to really be happy, somehow we must both consciously and non-consciously avoid errors in determining what is actually best for us, what we really need to do and what only seems necessary. We need some mechanism or mechanisms to make sure we only pursue the absolutely necessary desires, no matter our level of conscious attention. Unfortunately, Epicurus refuses to accept what Plato, Aristole and Lucretius did - the emotions can be just such mechanisms.
In order for normal people like us to succeed as epicureans given our limitations in concentration, we need to be trained. This is not news, and in fact, as you no doubt have noticed society does do a lot of training through the mores it passes along. So does organized religion. For example, until quite recently, society trained homosexuals to repress their sexuality, at the cost of tremendous stress and unhappiness. Many religions still do. And more positively, traditional sexual expectations for heterosexuals, though also stressful, perhapsworked to lower infidelity in marriage and by extention lowered the rate of divorce, arguably providing better homes for young children.
But how do such mores work? The way they are passed on, usually in childhood, makes it pretty clear they are not appealing to our rational faculty. We don't get logical or philosophical arguements for the rules of society or religion. Instead it seems clear that the emotions, including pride, fear, shame, anger and the need for love are deeply involved. Much more than involved.
In reality, we know it to be true from experience - it just makes sense - that properly calibrated emotional responses to situations are exactlythe efficient, practical, successful mechanisms by which we can increase the likelihood that we can have the well-trained character that would help us approach the goal of desiring only what is truly going to make us happy.
However, Epicureanism not only discourages this, it flatly claims that strong emotions are to be completely eliminated and generally speaking, all emotions should be eradicated. Even though Epicurus had the benefit of studying Aristotle's thinking on the matter which fleshes out convincingly the idea that in some cases its highly desireable,correct even, for you to strongly feel specific emotions.
As I think Plato, Aristotle and Lucretius made plain, and as I'll explain in greater detail later, the emotions are exactly the sort of thing to strongly influence you to act quickly and assertively to achieve a desire you're body thinks is necessary. Its unquestionable that to perform this service they need a significant level of monitoring. I argued that this insight is at the core of Plato's psychology. Epicurus, to his discredit, misses this point.
For him, the emotions are so powerful and damaging that they simply offer too much of a chance for error and so simply offer too much likelihood for pain. And the successful 'emotion-controller' would have to be already nearly perfect in character not to succumb to negative impulses. Thus Epicurus says we need to eliminate them.

The Last Words on Lucretius
As I said earlier, Lucretius thinks the mind controls cognition and the particles it is made up of are localized in the chest. On the other hand, anima, the vital spirit, is everywhere else in the body but the mid breast. Vital spirit’s particles move to the sway of mind particles and give the body sensation; thanks to vital spirit “even the teeth share in sensation”. Keep that in mind as we talk below about "registering" and "bodily awareness".
The View from 10,000 Feet
Echoing Plato’s analogy of the psyche with a country, where the rational part is the leaders and the spirited part is the military,
Lucretius says that while mind rules, vital spirit is the “body’s guard and cause of health”. It’s a safety mechanism to protect your flesh. In fact, vital spirit and flesh “twine together with common roots” and he thinks trying to tear them apart would be all but impossible, like taking separating the scent out of curry. He also describes it as being so thin and light, so sensitive, that even thoughts can make it move.
Getting Our Hands Dirty
Now that we have the basics on what mind and vital spirit, animus and anima, are, its time to get down to brass tacks. We’ve noted that Lucretius is a strict physicalist, believing that everything that exists is made out of physical particles. And he thinks that mind and spirit are one and the same thing, yet that mind is cognitive and spirit is not. But why should the same substance be able to act so differently?
Isn’t that paradoxical, or worse, impossible? Well, to avoid that conclusion he’s going to need to give us a satisfactory explanation for this apparent strangeness.
The reason, he says, why they can be the same “stuff” but act so differently is that while the mind is affected the same way as the body, vital spirit is “not one and simple”. What he means is that there are different properties to mind and spirit, they are not pure and simple like, say, hydrogen, carbon or iron. Instead mind and spirit are two subtypes of the same basic type of stuff, an “uber-soul” material, vital spirit. And vital spirit is not a basic element either. It’s a mixture of some sort, like water or soda.
We don’t need to go into the actual physical stuff he thinks make up vital spirit, the mind and spirit because its just not even close to being right as far as what we know to be the components of the nervous system. How could it have been, it would be about 1,500 years before the microscope was invented,
and roughly another 360 before the Electroencephalograph (EEG, the measurement of the electrical activity of the brain) became widely available.
But if you’re interested in knowing more, contact me and I’ll send you my fairly detailed discussion of it from my dissertation.
Whatever physical bits it is actually made of, in practice this vital spirit is basically what we’d call “bodily awareness”, the mechanism that allows us to do things like avoid running into people walking past us the other way even by the slimmest of margins. And as I’ve said before, given the way he describes them it’s fair to think of its components, animus and anima, as what we’d say are aspects of our overall nervous system.
So to put a bow on it, he is saying that the best explanation for our capabilities is that there is a physical system spread throughout the body that is responsive to outside stimuli, and that is directly connected to a centralized core, made of the same material. This core component uses in various ways the input to guide the actions/responses of the whole being. This centralized material, when activated by the spread-out system, is able to think and feel to varying degrees. Or as we’d say today, the nervous system allows for or creates the initial conditions for basic things like reflexes but also for our ability to measure and judge, and our ability for abstract thought.
Let’s be clear: Lucretius does not think that the chest-brain-stuff (animus) simply takes in data from the anima, stops the flow and considers the data, then sends commands to a body that is silently waiting. Instead the components that make up vital spirit allow for duplex communication between the brain and the rest of the nervous system throughout the body. It allows for immediate response to outside stimuli by real-time measurement - he explains that the body feels things that don’t quite rouse the spirit, and that our bodies are actually sentient – aware – in a way akin to the way the mind is. But this duplex process also allows for conscious analysis of the stimuli, the body’s responses, the results of the responses, what goals are being achieved, and what goals might be better, as well as the ability to seek after those goals. The body can run “on its own” but a conscious person can study her reactions and change her behavior to her preference. After all, they are made of the same stuff.
Yet its interesting to note and accept with Lucretius that our bodies register a lot more info than we ever actually register consciously. Think of micro-facial expressions, gut reactions, goose bumps, mosquito bites, or even navigating foot traffic on a busy sidewalk. These are all clearly things the body “notes” – or as I will put it sometimes, registers – even though you as a thinking person aren’t aware. And common sense tells us he’s right: not only are we not conscious of things such as mosquitoes biting us, we have no feeling whatsoever of things such as radiation, yet clearly our body registers it, sadly, to very poor results.
Emotion
Lucretius thinks that emotions are qualities of both animus and anima; they both process and communicate information, and so they can’t be irrational. But its hard for him to call them rational too. He’s convinced that emotions are felt physically in the heart and concludes in part from this that the mid-region of the breast is the seat of intellect and mind. But just because they are felt there doesn’t mean they are only felt there. In fact, he believes that there is more than one kind of emotion; one more or less purely mental (but of course physical) and “spirit-based” or “visceral” emotion that is much deeper and stronger but of course still “cognitive”.
On Lucretius’ account, due to the interactions of the physical particles that make up vital spirit, the mind emotes in an interesting way. Basically, anyone in an emotionally charged situation, anyone emotionally agitated, ends up at whatever emotion they end up at (or calm) by going through a progression from the burn of anger, to the chill of fright, and eventually back to calmness, as the duplex communication between the mind and spirit continues. Whether true or not, given the importance that anger and fear responses have to survival this makes some sense. These emotions are utterly important to our survival. The problem of course is that they can sometimes be a little antiquated and therefore lead us to misunderstand what our best reactions to a perceived stress should be.
The idea is that for some emotions, say fear for instance, up to a certain threshold only the mind is “emoting”, but there is a tipping point where the vital spirit is roused. As such, the chest-brain area is usually the part handling (and ‘showing” fears, but after a point the whole spirit system gets involved and you see other behaviors related to fear.
He also explains that while vital spirit moves to the “sway” of the mind, it does not always follow mind’s influence. At least sometimes, perhaps even most of the time, it does, but it doesn’t have to be that way. Whether it does or doesn’t depends on what beliefs are followed. When incoherent or mistaken beliefs are followed, we get bad desires and bad results. When correct beliefs are followed we get good desire and satisfaction. So to the extent an emotion keeps you from making a smart choice, or makes you feel like doing something stupid, or counter-productive, they would seem to be irrational, yet the real thing to blame here is not that system, its job is to protect your body, and its perceiving a threat!
But the animus! It’s the job of the animus to be rational, to oversee things. If the mind doesn’t do its job the times when it is within its power to do so, then the cause must be a physiological limitation, stupidity, laziness, or bad character. Nothing about emotions, or mind, or spirit makes it have to be that emotions and emotional responses have to be irrational or bad.
Conclusion
So we’ve seen Lucretius follow Plato and Aristotle very closely in some fundamentally important respects: 1) He’s keenly sensitive to the impact the emotions can have on other thoughts and on actions; 2) He believes there are two types of emotions; one more or less purely ‘mental’ and one ‘spirit-based’; more visceral and deeply felt, but still cognitive. (Of course both are still purely physical.) While some, say an existential dread, are cases where the mind is by and large the only part emoting, there may be a threshold past which the vital spirit is roused. Similarly, there can be emotions, say fear of a predator, that are more basic and active at the level of the spirit, but past a certain point the rest of the spirit system, the mind, may get involved; 3) he believes in duplex communication between the ‘mind’ and the body, and that 4) the mind and the body are both physical. In sum, he’s in basic agreement with Plato and Aristotle’s insights on ethics and psychology. At the very least nothing they said is directly contradicted by Lucretius.
The improvement Lucretius makes is that he not only understands that there must be a physiological explanation to all this, he tries to explain it. At length. And with some very imaginative, even penetrating insights. In fact, it was absolutely state-of-the-art science for 55 B.C. In fact, it was pretty state-of-the-art for a lot longer than that!
Combining the thoughts of Plato, Aristotle and Lucretius on the emotions, the mind, and ethics, we can see a pretty well worked out, defensible position. I call it the P-A-L account, and I call the theory of emotions in the P-A-L account the “pluralist account” of emotions. That’s in comparison to the visceral account, first developed by Homer, and the third candidate-account, which we're about to start discussing, cognitivism.
Review and Preview
We have a “scientific” (physiologically centered), state-of-the-art for its time explanation of how the mind and body are parts of a functioning system, how they interact and impact each other, and what thinking and the emotions are. And it all fits in just fine with the psychological and ethical insights of Plato and Aristotle. In fact, I think this P-A-L account is so defensible that I try to update it to current state of the art science in the final chapter of my dissertation, and that updated version is my own belief about how the emotions work in ethics.
Unfortunately, This P-A-L account didn’t exactly set the world on fire at the time. Not long after it was all put into place the Stoics came along and did every thing they could to bury it alive. The fact that I had to write this dissertation at all gives you a good idea of how successful they were. Unfortunately for us.
But before we get to them we have to look at the Epicureans, who have their own strengths and weaknesses to examine.

Lucretius' Conception of Mind
A Recap and a Rolling Start
As I said last time, Lucretius believes that when the mind is pushed-upon a wave of particles sets in motion, stirring the will. If you read my posts on Plato this should remind you of Plato's similar claims on how the outside world impinges upon the mind and body.
But to "stir the will" has to be explained in physical terms too, and Lucretius comes up with a theoretical physical system called "vital spirit" to do so. More on that later but for now we'll note that the physical substance vital spirit is diffused throughout out the body.
Whatever you call the stuff that moves the body around, the real trick is explaining the interconnectedness of the body and mind, of will and physical action, in a thoroughly materialist, physiologically centered manner. And a good, useful explanation will allow us to understand what it means for the mind to see and understand anything at all. Unless you're up to date on current neurophysiology, this is a pretty tall task.
So yeah, Lucretius has to be pretty bright to come up with such a system nearly 2000 years ago.
But enough back-slapping.
Isn't Physical "Soul" a cop-out?
On Lucretius' account every living thing is replete with "soul", which is completely material, just as much as your foot, ear and every other part of your body. (So don't you who believe in immaterial souls try to hijack this, and don't those of you who eschew such talk get upset!). Material soul is not a cop-out, but I'm going to tell you right now the concept gets pretty hairy so we're going take it nice and slow.
Lucretius actually uses two terms that can be translated into English as "soul": anima, which, for you religious types, is the one traditionally equated with what you mean by soul, and animus, a newer (relatively!) term he uses to make a very novel distinction.
Most simply put, in Lucretius' theory its the difference between the irrational and the rational mind. But even this is hiding some serious complexity. Both the "irrational" anima and the "rational" animus are part of (or two types of) the same stuff, vital spirit. Vital spirit is an admixture of various physical elements and, as I said above, is distributed throughout the body. We'll see that actually it works in a way similar to the central and sympathetic nervous systems. First lets focus on the part of all this that is most accessible to us, the animus, the rational part, what Plato and Aristotle called the psyche.
Animus or Psyche, its the Mind for Plato, Aristotle and Lucretius
For Lucretius, the animus, the rational part of the vital spirit, is responsible for all higher cognitive functions, things like abstract thought and planning ahead. So an able translation of animus is "mind', with all its implications of higher order thought and moral understanding. Lucretius at times also calls it "intellect", "head", "guiding principle" and "dominant force".
As funny as it may seem, Lucretius believed, (like many of his contemporaries, Aristotle and Homer) that mind is located in the middle of the breast. It will be very useful to keep that in mind so you can picture how he can talk about "thinking" in your chest, which will help you to better understand him overall. But let me say it again - like the rest of the vital spirit - mind is composed of matter.
A Primer on Mental Activity
Lucretius makes it clear that vital spirit causes sensibility in us, which allows the mind to have experience. And in order for action to occur, the mind must "judge" the benefits/merits of the results of an action. But this does not have to be done consciously. Just as important, the mind is not a 2-way transmitter (e.g., a walkie talkie) that, for example, "feels" a bug crawling on the skin and then tells the hand to squash it.
NO:
Think about why he is right that this doesn't make sense. If the mind were like a walkie-talkie, by definition only one end at a time can communicate. So if you had a bug on your leg, what would have to happen for you to get rid of it?
First, the body would feel the pressure on your flesh. For your mind to "know it" too would require one of four things:
1) Luckily, at the same moment when the body felt the pressure, the mind happened to not communicating out any messages and so able to receive transmission,
2) The body would not only feel the pressure on the skin, but also "knows" that the mind should stop transmitting and could force it to by accompanying important messages with a message such as "over" to tell the brain to start talking,
3) The body itself would just "know" how to stop the bug (like a reflex),
4) The body is constantly transmitting messages whether or not the mind is in a position to hear them, and sometimes the brain listens in for whatever reason.
However plausible you find any of these explanations, they raise more questions than they answer. Instead, Lucretius, like Plato and Aristotle, thinks there is a special, interactive and reciprocal communication between the body and the mind (and the emotions), a process I will continue to refer to as duplex communication. The mind and the body are both duplex transmitters, such as cellular phones, which allow two constantly running communications to both be understood by their targets.
YES:
More Details on Mind and Thought
According to Lucretius, mind is able to represent events to itself much faster than they actually occur or would happen. For example, if in real life, if Tim Lincecum throws his two-seam fastball 90 miles per hour, the hitter has .46 seconds to swing at it. Go ahead and imagine that now.
However long you took to visualize it, says Lucretius, it was quite a bit faster than .46 seconds. Another example of the relative speed of mind is how long it takes for the mind to "think ahead", as when you get a joke before its completed. (Here's an article on thought-speed).
I'll get into it more in the next post, but this also relates to something that will be very important to the P-A-L theory (when I finally flesh it out!). Not only is Lucretius really big on how fast mental representation is, he also makes it pretty clear that for the mind to "see" doesn't require deliberation. As he puts it, "within one moment of our sensation, many tinier moments are hidden whose existence reason discovers". And what he means by "discovers" is that the contents of our mental pictures are full of information "right there" and only need to be picked up or picked out. Yet we also superimpose assumptions on the information we process with our minds, so that things not "perceived by the senses" seem to us just like sense perceptions.
But what of it? Well it means that for Lucretius some (maybe even most) things are understood by the senses and not just "passively received" by them. And that means that a lot of what you might call "analysis" or "judging" doesn't require conscious deliberation. And as far as ethics goes, it also means that he is in agreement with Epicurus' saying that in a way we choose to engage in poor or irrational behavior because we often have a strong will to impose questionable - or even flat out wrong - interpretations on the things we see and hear.
We'll come back next time to look at the anima and more fully understand vital spirit.
