Stress

The following is a fairly meta post about stress and dealing with stressful times. I'm neither a neurologist nor a psychiatrist so I do not have an expert opinion on the topic, I have only my personal experience and the tactics I've learned to deal with it. People who are close to me often describe me as extremely calm and patient, which always surprises me. I never really think of myself that way but in the end appearances matter.

The reason I bring this up, of course, is because I'm feeling a lot of stress at the moment. A lot of it is personal and per my usual policy I won't go into details here. My usual response to events that provoke me is to stop, take a step back and breathe, let myself feel the emotion and once the moment has passed try to look at the problem as objectively as I can. It's important that I feel emotions but it's even more important that I act more than react.

In this article in the Washington Post (I strongly recommend you view the page in Privacy or Incognito mode of your browser unless you have an active account with the Post, also strongly recommended) they discuss a political issue revolving around stress and panic. The point that stands out for me is is this:

A new book by neuropsychologist William Stixrud and my friend Ned Johnson provides an explanation. The book, “The Self-Driven Child,” explains how calm parents give their kids more sense of control and help them perform better.


The science is simple. If you are calm, your executive functions handled by the brain’s prefrontal cortex — organizing, problem-solving, self-control, decision-making — perform well. If you are overly stressed, those functions decline as your brain floods with cortisol. Stress is contagious, and if you are in the presence of somebody who is out of control — a parent, an employer or, say, a president — your own executive functions decline.


“It’s a terrible thing for a chief executive of anything to be fear-mongering or emotionally reactive,” Johnson explained, “because all the bright capable people around you become less bright and less capable if they’re overly stressed.”
By creating an atmosphere of calm around me I encourage other people to be likewise calm and focused. My best man brought up this quality about me during the reception for my wedding, and my wife has commented on it as well. So tonight when I shared with my wife an angry letter I was writing she expressed a bit of surprise that I was really angry. It's true, I was and I still am. I'm struggling not to let my anger dictate my actions but I can't avoid allowing it to color them. The reason I wrote and sent the letter is because there's a problem that's been going on for a while with someone else and I needed to respond. I needed to take action, not simply react, and decide what I'm going to do going forward. I took some time to mull it over and I kept coming back to the same conclusion. So I made the decision and acted on it. I'm not happy about it. I'm angry that I've been forced into this corner. But after a great deal of thought I can't come up with a better solution. All the good choices have been taken away from me.

That's life, sometimes. We recognize we are powerless to correct or resolve a problem and all we can do is worry. We rant and rave and do everything we can think of to release that stress but so long as the circumstance remains unchanged it's a coping mechanism at best. Until change happens the stress never truly goes away. In this case there is something I can do to create change, but it carries consequences that I can do nothing about. It carries consequences for people on the periphery of the problem that they can do nothing about. It affects people I care about and I can't help them, I can only choose between evils. I hope that I've chosen the lesser of them but opinions will vary. In time I hope that my choice will be vindicated, but that's something only time will reveal.

History is repeating itself with my problem. I can't help but feel I'm repeating mistakes that others have made before me. There are people in my life whom I have mostly walked away from because they create too much toxicity and nobody needs more of that. I know some of them regret what they've done to me in the past because they've expressed it to me, but frankly I don't care. I don't trust them enough to believe that they truly feel regret, that they don't still believe everything they said and did was absolutely justified. I don't trust them enough to give them the chance to do it again. I'm worried (and will always worry) that I'm committing that mistake now, that the action I feel is justified at this moment will forever poison my relationship with people I care about deeply. Of course I run that risk no matter what I do; I know what some people want me to do but thanks to the corner I've been placed in I don't see how I can. So this is me trying to process the stress and powerlessness I feel over the options available to me. I've chosen to take a stand with as much openness and honesty as possible. I have offered to explain everything to the people affected by it but I can't make them listen and if I tell them anyway I can't make them believe me. I have to give them the choice and to honor whatever decision they make.

I'm not the only one with problems. I'm not the only one who is stressed. As the article I linked points out, everyone's stress has gone up significantly over the last eighteen months even for people who think our nation is on the right track. It's impossible not to feel stressed when there's so much insecurity and unpredictability in our daily lives. No one can see the future, but some have a clearer understanding of outcomes than others. I try to follow those who have a better track record but no one is infallible. So stress is something we just have to learn to live with. You can bury your head, block out the news and pretend nothing is happening outside of your bubble, but eventually life is going to intrude anyway. The path I choose is to acknowledge the stress and its sources and having done so continue moving forward. I can't change the past or present, I can only decide what I'm going to do about the future. Some of those decisions are going to be mistakes. I can't change that, either. But I can try to learn from my mistakes and try to make tomorrow better than today. If we all do that then we can ultimately forge a better world for everyone.

Wouldn't that be a welcome change?

Flying On Autopilot

What I'm about to discuss here is not ground-breaking. Many people will already be aware of the topic but I feel it worth exploring.

Working in IT I have necessarily learned a little bit about automation. Learning to write computer scripts to automate common tasks has been a significant boon to my life in computer support like when someone is constantly losing their network mappings or there's a folder that constantly fills up with old, unused temp files but never gets cleaned up and ultimately slows down the operating system. Yes, I'm looking at you Microsoft. not exactly hands freeThe point being is that scripts are labor-saving devices, tools we can launch to automate a process that would take more time and energy to do by hand. What's interesting is how we do this in our daily lives in ways that have nothing to do with computers. Did you ever drive somewhere familiar to you but with the mental note that you need to make an extra stop, then miss it? You were driving on autopilot. Did you find yourself talking about something with someone only to discover that neither of you were talking about the same thing?

We all develop strategies for dealing with everyday life, like taking one route over another on our way to work or navigating potentially hazardous social settings. We come by these strategies through observation, imitation and experimentation. I'm a little teapotAt some point in our lives we were taught strategies on various topics and tried them out, learning for ourselves what works or doesn't work. We then took those strategies and created mental scripts for ourselves to use them without wasting much time thinking about it. Once a situation matches a pattern in our scripts we automatically launch into the behavior we think is most appropriate to the situation we think we're in. But we don't always get it right; we sometimes fall back on our behavioral scripts when we ought to be paying closer attention to what's going on. It's something everyone does to some degree.

Why am I talking about this? For a couple of reasons really. One is because most of us aren't aware that we're doing this or really think about what it implies. Another is because we can get lazy and avoid change because that would require more energy than we're willing to commit. We often call this "getting stuck in a rut." Sometimes we get frustrated because we recognize we're in a rut but we're not willing to spend the energy necessary to climb out of it.

One of the most egregious examples of this behavior involves religion. There are a number of reasons why so many religions focus on ritual and repetition and one of them exploits the human tendency toward scripted behavior. They LiveThe more you do it the less you think about it, and we find that comforting. It relaxes us and allows us to fly on autopilot. It becomes habit-forming and we get locked into following the script we're taught to follow. Religion encourages this, particularly on religious matters. Don't think about it, just do as you're expected. Which means when religion gets things wrong its followers don't notice or don't want to think about it. They can get angry when confronted with it.

I've spoken before about the need to shock believers out of their complacency but I never really explored what I mean by it before. This is it. This is the nature of religious complacency: the human tendency to develop scripts for ourselves so we don't have to spend much energy thinking about what we're doing. Faith, in the religious context, means you're not supposed to take yourself off autopilot when it comes to religious matters. Anything that deviates from the script is a bad thing and might be punished severely. This is how loving, compassionate parents can turn into monsters who beat their children or harass them, even kick them out of their homes when it turns out the child doesn't share their beliefs. This is how good people do bad things: because they're following the script that's been ingrained into their behavior since infancy.

Something's gotta stop the flowHow do you break the script? It depends on the person. Some people cling to their scripts, too insecure to ever deviate from them. Some people are just too complacent, uninterested in putting forth the effort necessary to examine or modify their scripts. Some people just aren't aware that they're following a script and, once it's pointed out to them, will make them willing to take a closer look. Some people are frustrated because they recognize they're stuck in a rut and are open to change. You never know until you talk to them and find out.

I've spent the last three decades examining my scripts and adjusting them to the best of my ability. I still make mistakes and I still fly on autopilot far too often than is good for me. But I know I'm prone to it and I'm willing to change. Sometimes I just need help figuring out how.

The Cat and the Cave: Plato's Cave versus Schroedinger's Cat.

The Cave of...Link?

Plato's Cave is a famous philosophical construct wherein hypothetical prisoners are tied down facing one wall of a cave so they can't move their heads and look around. Behind them is a fire providing light for the cave, and between the fire and the prisoners are puppeteers moving back and forth holding various objects that cast shadows on the wall for the prisoners to observe. It's a hideously contrived scenario, but Plato used it to demonstrate the difficulty of expressing concepts through language when we don't have a concrete experience with those concepts. A prisoner might say "I see a book" based on a projection, but there's no book on the wall only shadow. It's only when they're released and can look around that they can see the real objects casting shadows. True understanding, Plato argues, isn't possible until then.

What I find curious is how many Christians love to inject Jesus into Plato's Cave. Plato wrote passionately about mistaking an image for the real thing, then Christians try to tie their invisible, intangible god as the fire lighting the wall. The mind boggles.

There are lots of ways to examine this religious hubris, but I found my thoughts moving in the direction of Schrödinger's cat. Like Plato's Cave it's a thought experiment, not meant to be taken literally. He made it to argue against the Copenhagen Interpretation of quantum superposition, but like the Christian version of Plato's Cave I would like to borrow it to make a point.

You wanna do WHAT?Schrödinger supposed that if you took a solid metal box, a cat, poison, a geiger counter, a hammer and a tiny amount of radioactive material you could construct a situation where the geiger counter is set to possibly detect the radioactive material, but it's not reliable because there's so little radioactivity. If it does, the geiger goes off which releases the hammer to smash the vial of poison. The poison kills the cat, whose only crime was to be imprisoned in the stupid box by silly humans. Does the geiger counter go off and doom the cat, or does the geiger counter miss the radiation and let the cat live? Under the Copenhagen Interpretation, Schrödinger argued, the cat is both alive and dead until the box is opened and the quantum superposition is observed.

Where am I going with this? Both Plato's Cave and Schrödinger's Cat address knowledge. We can't know things until we observe them, we can only speculate. Speculation is not knowledge. The best guess in the world is still just a guess until the answer is revealed. It's important to remember not to declare victory until we actually achieve victory conditions.

Remember Jesus in Plato's Cave? Nothing to see here.The Christians who borrow this allegory are doing violence to Plato's philosophy. In their cave all shadows are imperfect reflections of their god, which is why everybody has a different idea of what they're looking at. Plato himself asked why the prisoners wouldn't discuss the images between themselves and work out agreement on what they were supposed to be looking at, which is something we've been doing about gods for thousands of years. Of course, we're no closer to an answer today than we were ten thousand years ago. Christians agree that we're all prisoners in the cave, but they're the ones who actually know what those shadows represent! How? Because they feel it. Because they fake it until they believe. Because the Bible says so. Because...they just know, okay? Because shut up, that's why!

I'm constantly confronted with claims of knowledge in my daily life. Living in the age of information makes it a challenge to parse all those claims to separate the ones that are true from the ones that are false. Until I do, each one remains in a quantum superposition of being both true and false until it can be unpacked and examined. The shadows on the wall don't represent knowledge, they represent what we think is knowledge until our assumptions can be tested against the real thing. Always remains skeptical of people who are confident of the truth without being able to demonstrate how they know it. In the end, if you know you're right but can't explain it you should reconsider the possibility that you're actually wrong.

God is intangible, unknowable and ineffable. Except when he isn't. (updated)

One of the fundamental flaws I often criticize about religious belief is when believers want their cake and eat it too. Specifically, I refer to when their arguments rely too heavily on special pleading. And no, adding caveats to the definition of a god does not bypass special pleading. I can redefine chocolate as the essential first cause of the universe, but that doesn't make the definition valid.

But other examples of special pleading include arguments like this: god is mysterious, unfathomable and uknowable but somehow believers are granted special knowledge of who this god is, what it is and what it demands. Believers typically justify this via "special revelation," that they or their religious founders have been granted special knowledge by that god to carry out the divine will. Each religion and sect claiming special revelation typically considers the special revelation other religions and sects as heresy or at least attributed to human error. But since there are so many special revelations, how does someone not raised or converted to one particular orthodoxy distinguish which are the truly divine revelations and which are heresy? This problem is informally called the argument from inconsistent revelations. One of the supporting criticisms against divine revelation is the way it tends to follow cultural and geographical boundaries.


A point I've made before is that no religion has any better argument or evidence to support it than any other. Believers aren't basing their claims on independently observable phenomenon, they're projecting what they think should be true rather than what they can demonstrate to be true. There's no common experience for believers to reference so revelations vary from culture and region and even among different believers. This leads us to the skeptical position that if a god does not leave any traces for us to observe, then we have no reason to assume that anything we see supports the existence of this god. If this god is unknowable and incomprehensible, then we have no reason to assume anyone understands anything about it and can accurately represent it.


So which is it? Is a god knowable or not? If not then the discussion is closed. If so then show us examples that clearly demonstrate how this knowledge is valid and not human bias. Excuses aren't enough.

The Meaning of Things

Twice today I've been confronted by people who assert that "meaning" is some sort of property that can be found in objects or events. One asserted that beauty is proof of his god and another asserted that religion gives people meaning to their lives. So now I feel compelled to write about meaning and how we confuse what we want with what really is.

The first individual asserted "...it is the meanings which are encapsulated within it which make it beautiful, which make it something enlightening." Naturally I pointed out that this implies that meaning is an objective property that we can glean from something, but an objective property doesn't change based on the perspective of who is looking at it. An apple doesn't change into an orange when viewed from the proper angle. Meaning shouldn't change at all if it's an inherent property.

To further make his point this individual presented to me three actions that he believes have inherent meaning: a handshake, a hug to a crying child and a thumbs up gesture.

First the handshake. Apparently he wasn't aware of the history of greetings, from the Greek wristclasp demonstrating neither of you were armed (although this is disputed) but today having nothing to do with weaponry. When did it change from "I'm not armed" to "I'm pleased to meet you?" This is not established, but it serves to refute the idea that a handshake has inherent meaning, only the meaning we assign to it.

Then the hug to the crying child. Obvious this invokes some biological imperatives recognizing that as social creatures humans crave physical contact. The crying child is looking for reassurance but the person offering the hug may be more concerned with silencing the noise than with the emotional distress of the child. The meaning behind the hug may not be what you assume.

Finally the thumb up. It turns out there are six different meanings to this gesture which completely blows away any inherent meaning to it. But the most common meaning, the one meaning "okay" or some form of approval meant something very different to the Romans from whom we inherited it. During gladiatorial games when two opponents fought and one fell the crowd would extend their thumbs if they wanted to see the defeated fighter die. If they felt the fighter's combat was valiant and honorable they would hide their thumbs. So again, the meaning of the gesture has changed over time.

Objective properties don't change. If you can demonstrate that the meaning of something has changed then meaning is not an inherent property.

Related to this is the idea that we derive meaning from things. A painting or a sunset may inspire us, but what does that imply except that we have the capacity to be inspired? Did the inspiration come from whatever inspired us or do we project our own creativity onto what we see? For example, people have been inspired by the works of Jackson Pollock aka "Jack the Dripper" for decades, but I don't see why. When I look at it I see paint drippings on a canvas, not a key to the mysteries of the universe. But show me a nude by Rembrandt and I'll show you a love of the human form, particularly the soft curves of a woman. Someone else might see lechery and perversion, while yet another might see a blatant rejection of puritanical values.

I commonly hear that religion gives people comfort and offers meaning to their lives but I don't buy it. Like these paintings, religion doesn't have any intrinsic meaning or there wouldn't be so much dispute over what various religions mean. Instead what we have are examples of people projecting meaning onto religion, finding whatever they expect to see. How else could we have over forty-thousand different interpretations of the same religion? Religion is a blank canvas on which we paint, some by the numbers and others with free form. Put another way, religion is a blank page on which we write all our opinions and bias and call it sacred. Whatever religion offers that doesn't fit our expectations gets ignored or denied, often dismissed as metaphor or allegory for something else.

So what's the point? If meaning isn't inherent to anything, does that imply we should abandon all meaning? Of course not. When we find meaning in something that doesn't mean whatever we found was always there. It means we found it inside ourselves. We learned something new about ourselves and we're free to explore its implications. We can share this meaning with others and see if it resonates with their values as well. Perhaps the meaning we find will help others discover something new about themselves. We're just not justified in imposing that meaning on anyone else. Just because it has meaning for us doesn't imply that it must have meaning for everyone.

Justifying Belief Versus Non-belief

Something I've been thinking about lately are the justifications believers have for belief. Right off the bat, belief is usually treated as the default assumption. We should believe in their god because we can't prove them wrong. There are unbelievably intricate apologetics, hermeneutics, elaborate philosophical logic chains that try to hide the fallacies and false premises and of course the indefatigable fallback of "faith." We're unreasonable in our skepticism because we're not experts in their specific religious beliefs, their specific interpretations or their specific arguments. We should just leave them alone and let them believe, nevermind that they do little to stop people trying to force their beliefs on us. Nevermind that most believers aren't expert in apologetics, hermeneutics or philosophy either.

Curiously, they don't demand proof of non-existence for anything they don't believe in. Fairies don't need proof of non-existence, nor do vampires or werewolves. That's different, we're told. Fairies didn't create the universe or die for our sins. But how do they know?

There's an endless list of things we don't believe in that don't require challenge because people aren't promoting their belief in them. They're not plastering their belief on billboards and cars and they're not voting based on how they think the unicorn living in their shoes want them to vote. We don't bother debunking such things because there's no need.

I'm often asked what I believe about the beginning of the universe or how life began. My answer is I don't know and that's okay. Not knowing gives us room to find out. We know the universe began because it's here. We know that life began because we're here and it's all around us. What we believe about those things is irrelevant to the fact that they're here. All that remains us for us to figure out the details. But it's hard to do that when our search for answers is hindered by declarations of faith that have no justification and don't fit the available evidence.

The burden rests on non-believers to challenge these justifications. It shouldn't be; we shouldn't carry the burden of proof or have to justify our non-belief. But since we're still in the minority we don't have much choice so all we can do is keep at it and keep refining our arguments. We can't have too many tools available to accomplish this task.

I Was Wrong

A lot of people who know me don't think of me as a particularly humble man. That would be because I'm not. I am in fact quite arrogant, or at least confident in the correctness of my assumptions. I'm aware that I turn off some people because of my air of arrogance. Other people are attracted to me because of my air of confidence. There's just no way to please everyone.

In fact, I'm wrong about things all the time. I don't project this awareness because that's not how I was raised, but please take my word for it that I am aware of it. I am not right about things more often than the average individual. I'm no polymath like Sherlock Holmes who can speak authoritatively on a wide variety of topics. I have areas of interest in science, literature and politics but I am at best an enthusiastic layman in those areas. My understanding is general at best rather than specific. I grasp the basic concept of quantum mechanics but not well enough to teach a course in it.

On occasion I get accused of being close-minded because I'm fond of arguing passionately about whatever I think is true. I don't just say what I think is true, I usually try to dig up sources to support why I think it's true. For the average discussion this can appear quite daunting. Add to that several decades of experience in constructing and supporting arguments in favor of what I believe and people can walk away with the impression that I'm a know-it-all who can't be told anything. I'd like to take this opportunity to explain why that isn't true.

I do possess sufficient self-awareness to realize I'm not always right about everything. There are things I've thought about and researched sufficiently to feel comfortable about, and I often write about them. I use feedback (when I can get it) to test and refine my arguments. It's an ongoing process and at this point many of my arguments are very polished, especially when it comes to topics that come up in popular discussion. For example when someone attempts to justify their belief in their god because I can't prove their god isn't real, I have a pithy reply to demonstrate how their logic fails. I came up with that pithy reply after years of trying to explain the burden of proof at length and gradually refining my explanation into a simple, penetrating response. Most of the time, however, I include subtle caveats into my statements. "It seems to me." "As I understand it." "The evidence suggests." These are mental bookmarks intended to remind me that I am ultimately agnostic when it comes to absolute statements.

When I'm wrong and I know it I try to explicitly state it as such. "No, I was wrong." "I stand corrected." I then try to point to the source demonstrating how I know I was wrong and what the correct answer is. I'm human and I sometimes try to rationalize how the new information still allows me to be correct (seriously, who wants to be wrong?) but I try to be brutally honest with myself when I know I need to correct my assumptions.

In the end, changing my mind is dreadfully easy: all you have to do is show me the evidence.

Free Will vs. Determinism

This is a very tricky subject that delves deeper into philosophy than I'm really comfortable with. I enjoyed my introduction to philosophy class in college, and the professor clearly enjoyed debating with me, but I got turned off the topic when I started encountering people claiming Aquinas' Five Ways as proof that their god must exist since the concept is logically sound. The problem is that logically sound arguments don't always translate to physical evidence; just ask the Nineteenth Century scientists trying to verify cosmic ether.

So let's begin at the beginning. What is "free will?" The definition provided by that link gives us a good place to begin: “Free Will” is a philosophical term of art for a particular sort of capacity of rational agents to choose a course of action from among various alternatives. Summarized even further, it's our ability to make choices free from interference.

"Determinism" then is the polar opposite of free will. Again citing this link, Determinism is the philosophical idea that every event or state of affairs, including every human decision and action, is the inevitable and necessary consequence of antecedent states of affairs. Free will is impossible because we're necessarily bound by the choices and events that came before each choice.

The jury is out on this topic, with new evidence coming to light tipping the scales back and forth. The latest findings in neuroscience suggests that free will is just an illusion born out of biochemistry.

I still like the idea that I have free will, that the agency behind my choices aren't strictly determined by biochemistry and causality. I can choose to set myself on a different path if I'm determined to do so. However, I can't dispute the evidence leading to the answer that it is all biochemistry and causality.

Does that have to be the end of the conversation? Our brains are based on complex neurology that produces an emergent property we call consciousness. The foundation of our brains is really very simple and its components can be found in any creature with neurons. Can it be that free will is also an emergent property from the complex interaction between biochemistry and causality? Biology may make us prone to certain actions with causality boxing us into a series of choices, but we've seen how quantum effects collapse in the presence of an observer. We behave differently when we know we're being observed or tested than if we think we're acting on our own.

I think it's a hideously complex topic, and until we gain better understanding of the nature of consciousness itself we won't be able to answer this question with any accuracy. For now I'm going to continue to hold on to the comforting illusion of free will as a justification for holding myself accountable for my actions.

The Problem of Evil

Today I ran across a discussion that rehashed the Problem of Evil, specifically some problems I had early on with how an all-powerful, all-knowing and benevolent god can create an entire universe knowing that the fate of its creation is to have 99% of it suffer in eternal torment that it inflicts on them. Some Christians try to reconcile this by saying that their god isn't truly omniscient, or doesn't exercise his omniscience all the time (ref: Mr. Deity). Others claim that he willingly refrains from exercising his omnipotence in order to preserve free will and so forth. None that I've met are willing to concede that if he exists he saw the wholesale death and suffering of humanity and did nothing to correct it because he either doesn't care or wants that result.

The problem, as far as I see it, lies in magical thinking. You have this god who is supposed to be looking out for you and your best interests. The world doesn't really seem engineered to give you the best life experience; every day is a struggle and it often seems that events conspire against you. But this can't be possible if your life is being overseen by a loving, all-knowing and all-powerful god. Therefore there must be another reason for it, one that is beyond your comprehension because the alternative is that one of your assumptions about your god is wrong and if you follow that thought process you might discover that all of your assumptions are wrong and you might have to abandon the idea altogether. So we fall back on our default assumptions and assume it'll all make sense later on, probably after we're dead. "Jesus, take the wheel."

It's one way to cope, although the cognitive dissonance it necessarily creates is never comfortable. But Christianity has an answer for that, too: "Blessed are those who suffer for doing what is right. The Kingdom of Heaven belongs to them." Of course, in doing so you run the risk of ignoring obvious solutions to temporary problems in the name of validating your religious beliefs. Simple, easy things like making the world a better place instead of assuming it's pointless since your god will wipe it all away to create a new earth to live on.

Naturally, different Christians will have different answers for how they attempt to reconcile this problem. Some will deny it's a problem altogether. Others will present different variations or apologetics. Nevertheless, I haven't seen any answers that don't fall back on magical thinking. Their god created the world by magic (divine, but still magic), therefore the answers must be magic as well. You just have to have faith that it's true.

And of course, SMBC Comics offers the simplest explanation possible.
