      Entering (submersion 3 times with a certain prayer and crossing yourself) in water springs of orthodox saints(which are near or in monasteries) give very much power and sureness to people with depression, panic attacks, schizofrenia and other soul illnesses before getting to the eucharisty that heals all soul illnesses. There are some springs of mother of God Maria that heal all soul illnesses. Spring at the Monastery of st. Paraskevi at Tempi in Greece is one of many springs of saints in Greece. If you have chronic fatigue it is from masturbating, watching pornography, hate etc. 99% of all illnesses are from soul
      If you have diseases, bad luck, impotence, you can only have a discussion with the same person, etc. it can be from witch spellings. In the Zlătari church in Bucharest, every Wednesday at 17.00 it is read the akathist to St. Cyprian and st. Justin against charms and all demons. This akathist can be ordered at any other Orthodox church if you are baptized Orthodox. You must write your name and give it to the person receives the sheets, it is usually at the entrance to the church.

    honestly, Its crazy how much easier information is retained when you voluntarily seek it. When i was in school i would have never listened to this and would have been dying to get out of there. Now that i have the ability to learn on my own time I retain and look for information on a much higher level. Incredible.

      @ElFlow66 some side effects in society would probably be: people are more social and interact with others more, no more education insitutions, only universities which function as like areas to get more education in fields you want to learn more about and do as a career, not sure how this would affect the industrial and work like system we have today as life isn't all about having fun, there are some things you'll have to do that will be challenging, annoying and tedious but once you finish it you'll feel a lot better with the finished product

    • Safwaan

      @ElFlow66 wholeheartedly agreed, it would be great if school wasn't "sit in a room and be like a robot, don't act human at all and be forced to learn something that's not important and your not interested in" instead it would way way better if school was basically like showing and letting you do the things you want to and are interested in, and stuff that's not included can be shown to you by other means (courses, online tutorials, etc). Just curious how will the school system work then? If all you do is learn stuff you want to then how will going up school systems work? Cause I mean it's gonna get boring doing guitar or other classes for 20 years straight, also I think some changes would help like they're could still be a history or other class to learn but it's mainly just doing stuff for fun.

    This is an absolutely amazing lecture because he doesn't just dive into the subject. He outlines the way to approach it without thinking in boxes. Its a refresher for scientific and critical thinking abilities. Designed to help unravel a very complex and challenging subject. I think I'm going to be spending some quality hours here with the Dr. One of his lectures on KoKo the gorilla brought me to this playlist.

Hopefully I see you some day at Stanford University

      @Dark Star King Then that’s why you either go to med school, complete residency & etc and become a psychiatrist, or complete a master’s and PhD and become a licensed psychologist. Or just become a teacher. Psychology has a lot of fields that it can work at: businesses & organizations, schools, government bodies, hospitals, etc. Especially since more people are open about mental health and willing to seek help which makes this occupation one of the better ones during these times.

    I think we all underestimate the importance of teachers like professor Robert Sapolsky. A teacher, like him, not only tries to listen, see, and understand his students, but to also engage, educate, motivate and inspire his students. A great teacher wants to learn from his students and wants his students to ultimately surpass him and his work. He doesn't gatekeep, but enlightens others, seeks and invests in their full maturity and development. You can see he has passion and a sense of purpose and wants to guide others to their own success.

      The same for me, its also the case for animal studies,people have attempted to replicate the findings from the 80s but to no avail.
      Interesting how ( if any one knows a specific word for this please tell me) previously valid information makes its way into society but over time is found out to be wrong.But we never become aware of the change and still hold certain ideas to be true.
      My head is full of these false notions
      An example being we only use 10% (or a small %age) of our brains which possibly has its origin in Dale Carnegie’s-How to Win Friends and Influence People. Or a least seems to be popularised by the book

      @Mark Ellermets - i just saw this for the first time, so sorry that i am answering so long after your post.... I am with you, in believing that there are free-will aspects to our lives (the universe needs some randomness). however, there are so many tiny things that you would think are free-will actions, yet, even when we make a choice to do something outside of our pre-programmed biology, it is our pre-programmed biology that decides what that 'something' different might be. LOL
      my favorite proof is the twins example -- where the 2 twins who had been separated their whole life had some strange quirks that were unique to them (such as needing to flush a toilet twice). it's really odd how such a trivial act can be so set in humans due to our biology. ;)

    • Prog Rocker

      @Sylvia Skinner - Hi. I don't think anyone answered you, so even tho it's been so long, i will. The prof asked the question as if he didn't expect anyone to agree with evolution because he didn't want to lead (aka bias) the class into thinking he expected them to agree with evolution. A student who doesn't believe in it will assume the college professor does, and therefore would be reluctant to admit non-belief. however, given the prof asks it in a way that sounds like he expects someone to not believe, a non-believer would feel safe to raise their hand.

      @Serpentine S how does nature vs nurture remove the individuality of a human? Even ants are individuals.... or wait, what category are you thinking in at the moment? Do you mean individuals as in being able to think for ourselves, transcending our nature and nurture due to our complex conciousness, or individuals as in DNA? Or individuals as in having different facial features?
      There's a fuck ton of ways to see ourselves as individuals.... so what category do you fit in?

      @Will Sani But his entire class is something very complicated boiled down to a simple category... Human Behavioral Biology 🤣
      Nuanced would be listing genetics, biochemistry, physiology, etc all the categories within human biology that helps determine behavior. Saying a simple/lazy mind will fight complexity is simple/lazy minded since there's an evolutionary and logical reason to why humans generally favors simplicity. I assume you are smart enough to know what I'm talking about.
      There's also danger in over-complicating things....

      Yes it is a great breakthrough and allows for many to get a better education if they deem to do so. but some will be reluctant like this tommy tooter who called DR. Sapolsky a ghoul for his stance on religion and said he was in Kenya carving on gorilla brains.. in several of his delusional videos. last one being a female child was born. They do not go by biology instead they will to believe anything off tumblr

  • halluska
    halluska 3 months ago +17

    As a native speaker of Finnish, I can refute the example given by Sapolsky here. We in fact do differentiate between the sounds of b and p. We call the former the hard p and the latter the soft p. The confusion must be because of the letter b doesn't naturally occur in Finnish but we do have few loan words that have that letter/sound in them or alternatively the particular dialect the person in question had been grown in that Sapolsky was talking to didn't differentiate between the sounds of b and p. I'm a Southern Finnish speaker and an example of we differentiating these sounds would be banaani (a banana) and paeta (to escape). You wouldn't pronounce the letters b and p in the same way here at all. But in a more similar manner as would any English speaker do. P having a much harder and harsher quality to it and b having a much softer and thicker quality to it.
    I think a more appropriate example of this phenomenon would be Japanese not differentiating between the sounds of r and l that are found in so many other languages, including English. That is why the English words pray and play would both be romanized as プレー (puree). The sound represented here as p and r would aurally sound a mix between the sounds or l and r.

      If you take Spanish, at least that spoken in Spain, Spanish people cannot distinguish between B and V uttered at the beginning of a word.. I have pronounced 'viaje' (voyage or journey) with both a b sound and a v sound at the beginning of this word and Have been told by Spanish speakers that there is no difference.

    • Truemmerprinz
      Truemmerprinz 3 months ago +2

      Thanks for the info!
      I was researching this right after the part. I actually don't know a lot about the Finnish language, other than that I like what it sounds like. However I was well aware of the fact that "p" is used a lot in the Finnish language. I couldn't find a lot words including "b", but in those I found, the "b" was pronounced like it is in the English language. Furthermore, since I already knew that Finnish uses the "p"-sound like the English language does, I was a bit confused at the thought of why, as a Finnish person, you should mispronounce "pear" as "bear". It would make much more sense the other way round, if "b" is the less common sound. So this story either had nothing to do with the person he talked about being Finnish, or it's made up for entertainment purposes (which I wouldn't find that bad, some of my professors did this too, and it often was obvious that it's made up).
      I find these lectures very interesting, but there were other points that, unfortunately, take away some of the credibility of this man. Like that the theory and studies about synchronizing ovulation in hamsters and especially humans have been doubted, couldn't often be reproduced and seem very flawed.

      @MADHAV the_ebullient_storm SARAF heres anothers perspective. The Finish guy told him to practice doing testiclar biopsies on a bear. The Finish social/cultural/psychological programming had taught his hearing not to catagorise the diff between the sound of p & b. So he could only imagine he was saying "practice on a pear" when in actuality he was saying "bear". Language filters can cause a barrier to hearing sounds correctly and many other forms of sense data.
      Our brain often categorises incorrectly according to socially indoctrinated filters. This means we also sometime lay an incorrect catagory over sensately experiential facts and are unable to discern that we have done so. Thus we often cannot hear or see or smell etc actual facticity because we arent free of catagorical barriers.

      @Senor Lopez I don't think any of us "puny humans" can fully grasp the concept of God. If we could, then we too would be gods (in theory). The part where it's insinuated that religious people aren't intelligent, is where you say" I assume most educated people are agnostic". Not giving themselves totally and unconditionally to a single loving God. I'm aware of how the Bible was comprised, and who put it all together. Sometimes things don't make sense to us, but to the supreme controller, everything is understood by he/she. We are but mortals, talking about things which we do not fully comprehend. I consider the evidence, and formulate my "opinions" from that, I also don't try to force my beliefs on anyone, or put them down for their own beliefs. When I was young I used to believe in greek mythology. Maybe all religions are based off of the tablets of Thoth...? Idk, anything is possible. I believe in God, but upon the existence of new evidence, I could be interpreted as "agnostic" also. I hate putting any one thing into a single box. Lot of variables, and 2000 years is a long time for something to get lost in translation. But if there is a creator, I'm sure the book He has intended for us to have, is the one that He also produced. Even if it was through us "puny humans". Have a great day 😎

    • Senor Lopez

      @It's_All_Fugazi Where did I say that intelligent people don't believe in God? I'll elaborate on my point since it doesn't seem to have hit the mark I wanted it to, educated people are more likely to be open to other ideas rather than the blind "faith" that the church would prefer you to have.

    Lecture One Notes
    57 Minutes
    Minutes 1-10:
    - Professor describes a circumstance in which a male with no history of inappropriate behavior begins to act out of character. He acts in a way that displays violence, illegal sexual activity and rash decisions that lack logic. The professor justifies the presence of this behavior by attributing it to a genetic mutation.
    - The Professor presents four subjects and asks the class what they all have in common.
    1. A woman being on her period
    2. A brain tumor
    3. Junk food
    4. Anabolic Steroids
    - The thing the four topics stated above have in common is that they have all been used as reasons to justify murder in a court of law
    - The point of this example is to present evidence that the actions of the body directly affect the actions of the brain and, thus, contribute to behavior
    1. A woman being on her period (hormonal changes lead to aggressive behavior)
    2. A brain tumor (Effects on the amygdala lead to behavior that is typically out of character)
    3. Junk food (Causes dangerous changes in blood sugar level which lead to behavioral alterations)
    4. Anabolic Steroids (Large scale hormonal changes which lead to behavioral alterations)
    - Professor ends first ten minutes of lecture by stating the point of the course. The point of the course is, in part, to understand the relationship between the brain, the body and behavior under various complex circumstances.
    Minutes 11-20:
    - The next ten minutes is spent discussing an issue that arises when one attempts to understand the relationship between the brain, body and behavior. That issue is singular categorical thinking. Categorical thinking is approaching the situation and only considering one variable that may be attributing to behavior.
    - The benefit of categorical thinking is at times it can give humans needed structure to approach a topic.
    - The negative side of categorical thinking regarding this course are as follows:
    “When you pay attention to categorical boundaries you do not see big pictures.”
    “When you think categorically you underestimate how different two facts are when they fall in the same category.”
    “When you think in categories you can overestimate how different two things are when there is a boundary in between them.”
    Minutes 21-30:
    - Professor begins the next ten minutes of class by reiterating the goal of this class “The goal of this class is to take this big complex issue of behavior without falling into thinking in categories.”
    - The professor then gives examples of people who thought categorically and the flaws that followed because of such.
    • “ Give me a child at birth from any background and let me control the environment in which it is raised and I will turn him into anything I wish him to be whether doctor, lawyer, beggar or thief.” John Watson
    John Watson was one of the founders for the school of behaviorism.
    He believed that you could dictate a person’s development via their environment. However, the professor points out the obvious flaws in this train of thought.
    • “Normal physic life depends upon the good function of brain synapses and the mental disorders appear as a result of synaptic derangements. Synaptic adjustments will then modify corresponding ideas and force them into differing channels. Using this approach, we obtain curers and improvements but no failures.” Antonio Egas Moniz (Famous Portuguese Neurologist who developed and received a Noble Peace Prize for developing Frontal Lobotomies)
    Synaptic Adjustments= Frontal Lobotomies
    The speaker of this quote did unnecessary damage to the brains of hundred because he was thinking in a singular categorical fashion.
    • “The selection for social utility must be accomplished by some social institution if mankind is not to be ruined by domesticated induced degeneracy. The racial idea is the basis of our state and has already accomplished much. In this respect we may, and we must rely on the healthy instincts of the best of our people; for the extermination of elements of the population loaded with dregs.” Conrad Lorenz (One of the founding fathers of the Ethology/Nazi Propagandist)
    The errors in Conrad Lorenz Nazi styled categorical thinking patterns are obvious given the mass genocide that followed similar categorical thought patterns.
    - After these three examples are given the professor clarifies that this is not the way in which we will approach analysis behavior.
    - The way in which the professor states behavior needs to be analyzed is as follows:
    1.) Address what the behavior looks like.
    2.) Address what went on neurologically one second before the behavior took place.
    3.) Address what environment stimuli provoked that neurological response.
    4.) Address what hormone level was presence for the organism to be affected by the environment int hat way.
    5.) Address the gene that was coded for that hormone and how the structure of that gene may affect that hormonal response.
    6.) After accessing genetic coding note how pre-natal development may have affect that genetic coding.
    - The idea is to not get caught in a singular categorical way of thinking, but to see the overwhelming nuance and various factors of why an organism behaves in the manner it does.
    - The professor concludes this segment of ten minutes with depositing the question of what is the purpose of a chicken? The answer being that the chicken is just the eggs way of creating another egg.
    Minutes 31-40:
    - The professor uses this segment of ten minutes to address the three intellectual challenges you as a student may have in not thinking categorically. The three challenges are as follows:
    1.) Understanding and Accepting that man is just like any other species.
    • The professor gives the example of how female hamsters and homo sapiens have menstrual cycles that will sync up when in close living conditions. The name of this phenomenon is called the Wellesley Affect and the McClintok Effect.
    2.) Accepting that as a species we have a similar physiology to other species, but we utilize it at times in a way completely different from any other species.
    • The example that is given to support this is the way in which calories are burned. A chess player can burn the same number of calories as a full-grown chimp killing a predator. Same physiology but, at times, utilized in a completely different way.
    3.) As a species we have similar physiology to other species but, at times, completely different behavioral patterns.
    • Example given to support this point is the mating ritual of homo sapiens versus that of hippos.
    Minutes 41-50:
    - Professor describes that the first portion of the course will be identifying each category used to dissect behavior.
    - Professor describes that the second part of the course will be used as an opportunity to use the categories you just learned to explain and ration various human behavior.
    - Books assigned:
    • “Why Zebras Don’t Get Ulcers” Robert Sapolsky
    • “Chaos” James Gleick
    - This segment of ten is concluded with the professor promoting Chaos by saying that it perfectly communicates the concept that human behavior is not something you can understand and fix by breaking it apart into its most small pieces and putting it back together but must be understood in the way a the structure and function of a cloud is.
    Minutes 51-57:
    - Last few minutes of the class are the professor detailing the structure of the class for the following semester.

    I thoroughly enjoyed this. I have been a dog groomer for nearly 30 years and in the process of teaching them to cope with a process that can induce fear and anxiety of which that is the most unnatural process one species can perform on another.....while awake and aware - and whom is the most unnatural species on the planet as genetically they are the wolf......well, they have become my gurus and have taught me not just dog psychology but help me understand and make sense of human psychology and also behavior. Boy, that was one long sentence!! Tried to get as much info in as possible.....what I am trying to say is - dogs have taught me more about being human than any human....well, other than myself and learning to read the patterns of feelings, emotions and how my gut instinct, vagas nerve, pituitary and amygdala interact with the dogs same systems well, is absolutely amazing. Beast on beast interaction but with me coaching, encouraging and instilling calm and stability. I never blame a dog for any behavior they give me thus I feel the same with ppl.....fear, unmet needs, isolation, depravity, environment, genetics and epigenetics play a huge role in triggers of behavior. I am curious about human behavior.....innately so! Curiosity is where it's at!! I found Sapolsky utterly engaging and would have loved to take the course or have an in-depth conversation. Will look for his book.....

    I'm reading Sapolsky's book "Behave" and I had to Come back to this video, the reason I fell in love with this brilliant man. I never had lecturers like this in University and I imagine id have been a much better student if I did. I absolutely love learning from him.

    The basic quality of a teacher is to provoke interest in his/her students on the subject if not it's their first failure, Here's one guy who really did that, absolutely riveting!
