“Pathology can indeed evoke experiences of Absolute Godliness, but not all God experiences are caused by pathology. They can also occur due to disturbance in the geomagnetic field of our planet, consumption of psychedelics, excruciatingly extreme level of stress during a near- death situation, or ultimately through a natural and healthy procedure of meditation or/and prayer.”

“Neurobiological differences have been demonstrated between dissociative identities within patients with DID and between patients with DID and controls. Given the current evidence, DID as a diagnostic entity cannot be explained as a phenomenon created by iatrogenic influences, suggestibility, malingering, or social role-taking. On the contrary, DID is an empirically robust chronic psychiatric disorder based on neurobiological, cognitive, and interpersonal non-integration as a response to unbearable stress. While current evidence is sufficient to firmly establish this etiological stance, given the wide opportunities for innovative research, the disorder is still understudied.”

“Imagine yourself having a fight with your romantic partner. The tension of the situation makes your limbic system run at full throttle and you become flooded with stress hormones like cortisol and adrenalin. The high levels of these chemicals suddenly make you so damn angry, that you burst out in front of your partner saying, “I wish you die, so that I can have some peace in my life”. Given the stress of the situation through highly active limbic system, your PFC loses its freedom to take the right decision and you burst out with foul language in front of your partner, that may ruin your relationship. In simple terms due to your mental instability, you lost your free will to make the right decision. But when the conversation is over, and you relax for a while, your stress hormone levels come down to normal, and you regain your usual cheerful state of mind. Immediately, your PFC starts analyzing the explosive conversation you had with your partner. Healthy activity of the entire frontal lobes, especially the PFC suddenly overwhelms you with a feeling of guilt. Your brain makes you realize, that you have done something devilish. As a result, now you find yourself making the willful decision of apologizing to your partner and making up to him or her, no matter how much effort it takes, because your PFC comes up the solution that it is the healthiest thing to do for your personal life. From this you can see, that what you call free will is something that is not consistent. It changes based on your mental health. Mental instability or illness, truly cripples your free will. And the healthier your frontal lobes are, the better you can take good decisions. And the most effective way to keep your frontal lobes healthy is to practice some kind of meditation.”

“Sonnet of Conspiracy Perhaps there's a monster under the bed, Perhaps there's a boogeyman in the closet. Perhaps they're sterilizing kids with vaccine, Perhaps they're controlling all with a radio set. Yes our science is well advanced, But not advanced enough to control minds. Besides mind-control needs no fancy tech, When people are run by smartphone chimes. Tales like these are good for entertainment, Amongst a bunch of kindergarteners. But being adult requires the use of reason, Without submitting to prehistoric fears. Treating insecurities with common sense, Anyone can manifest civilized sentience.”

“Biases continuously try to keep us from recognizing and understanding those biases. For example, racial biases keep us from understanding racial discrimination, just like religious biases keep us from understanding religious discrimination and cultural biases keep us from understanding the inhuman habits in our cultural traditions.”

“Only the neurosurgeon dares to improve upon five billion years of evolution in a few hours. The human brain. A trillion nerve cells storing electrical patterns more numerous than the water molecules of the world’s oceans. The soul’s tapestry lies woven in the brain’s nerve threads. Delicate, inviolate, the brain floats serenely in a bone vault like the crown jewel of biology. What motivated the vast leap in intellectual horsepower between chimp and man? Between tree dweller and moon walker? Is the brain a gift from God, or simply the jackpot of a trillion rolls of DNA dice?”

“We have minds that are equipped for certainty, linearity and short-term decisions, that must instead make long-term decisions in a non-linear, probabilistic world.”

“There are two ways to think about ourselves. One is as biological organisms, products of evolution and natural selection. From this point of view, humans are defined by our genes, and the purpose of life is to replicate them. But we are now emerging from our purely biological past. We have become an intelligent species. We are the first species on Earth to know the size and age of the universe. We are the first species to know how the Earth evolved and how we came to be. We are the first species to develop tools that allow us to explore the universe and learn all its secrets. From this point of view, humans are defined by our intelligence and our knowledge, not by our genes. The choice we face as we think about the future is, should we continue to be driven by our biological past or choose instead to embrace our newly emerged intelligence?”

“When the neocortex wants to do something, it sends a signal to the old brain, in a sense asking the old brain to do its bidding. For example, breathing is a function of the brain stem, requiring no thought or input from the neocortex. The neocortex can temporarily control breathing, as when you consciously decide to hold your breath. But if the brain stem detects that your body needs more oxygen, it will ignore the neocortex and take back control. Similarly, the neocortex might think, 'Don't eat this piece of cake. It isn't healthy.'' But if older and more primitive parts of the brain say, 'Looks good, smells good, eat it,' the cake can be hard to resist.”

“The question of how the neocortex works can now be phrased more precisely: How does the neocortex, which is composed of thousands of nearly identical cortical columns, learn a predictive model of the world through movement? This is the question my team and I set out to answer. Our belief was that if we could answer it, we could reverse engineer the neocortex. We would understand both what the neocortex did and how it did it. And ultimately, we would be able to build machines that worked the same way.”

“Reference frames in the old brain learn maps of environments. Reference frames in the what columns of the neocortex learn maps of physical objects. Reference frames in the where columns of the neocortex learn maps of the space around the body. And, finally, reference frames in the non-sensory columns of the neocortex learn maps of concepts. To be an expert in any domain requires having a good reference frame, a good map.”

“Why do we have a singular perception if we have thousands of models? When we hold and look at a coffee cup, why does the cup feel like one thing and not thousands of things? If we place the cup on a table and it makes a sound, how does the sound get united with the image and feel of the coffee cup? In other words, how do our sensory inputs get bound to a singular percept? [...] Instead of converging onto one location, the connections go in every direction. This is one of the reasons why the binding problem is considered a mystery, but we have proposed an answer: columns vote. Your perception is the consensus the columns reach by voting.”

“Not that long ago, the question 'What is life?' was as mysterious as 'What is consciousness?'. It seemed impossible to explain why some pieces of matter were alive and others were not. [...] At some point in the future, we will accept that any system that learns the model of the world, continuously remembers the states of that model, and recalls the remembered states will be conscious. There will be remaining unanswered questions, but consciousness will no longer be talked about as 'the hard problem'. It won't even be considered a problem.”

“To hold on to a false model, such as a flat Earth, requires dismissing evidence that conflicts with your model. Flat-Earth believers say they distrust all evidence that they cannot directly sense. A picture can be fake. An explorer's account can be fabricated. Sending people to the moon in the 1960s could have been a Hollywood production. If you limit what you believe to only things you can directly experience, and you are not an astronaut, then a flat-Earth model is what you end up with. To maintain a false model, it also helps to surround yourself with other people who have the same false beliefs, thus making it more likely that the inputs you receive are consistent with your model. Historically, this entailed physically isolating yourself in a community of people with similar beliefs, but today you can achieve a similar result by selectively watching videos on the internet.”

“We face a dilemma. 'We' -- the intelligent model of ourselves residing in the neocortex -- are trapped. We are trapped in a body that not only is programmed to die but is largely under the control of an ignorant brute, the old brain. [...] We try to control our old brain's destructive and divisive impulses, but so far we have not been able to do this entirely. Many countries on Earth are still ruled by autocrats and dictators whose motivations are largely driven by their old brain: wealth, sex, and alpha-male-type dominance. The populist movements that support autocrats are also based on old-brain traits such as racism and xenophobia.”

“This is what nationalism does. It blinds you to rational arguments that may threaten the integrity of your nation's image, just like fundamentalism blinds you to rational arguments that may threaten the integrity of your religion's image. It's a smoke screen created by the mind and sustained by the mind by means of sentiments which are mostly biases in action, set in motion to protect your barbaric allegiance to your little tribe.”

“Imagine for a moment that we are nothing but the product of billions of years of molecules coming together and ratcheting up through natural selection, that we are composed only of highways of fluids and chemicals sliding along roadways within billions of dancing cells, that trillions of synaptic conversations hum in parallel, that this vast egglike fabric of micron-thin circuitry runs algorithms undreamt of in modern science, and that these neural programs give rise to our decision making, loves, desires, fears, and aspirations. To me, that understanding would be a numinous experience, better than anything ever proposed in anyone's holy text.”

“You are defective – you are imperfect – you are far from the best version of yourself – but you have a 3 pound of lump of jelly inside your skull containing more nerve cells than there are stars in our galaxy, so be aware of this magnificent and miraculous possession of yours, because with that very awareness will you be able to trump all your shortcomings and imperfections and rise above them as the Lord Saint victorious.”

“In the digital age, the strongest defense for children is not a firewall on their devices, but rather a brain circuit strengthened by silence and real connections.”

“Almost every single intellectual has been obsessed with an illustrious question - what drives morality! Yet none of them has been able to find an actual answer to this question. All that they have done is to publish tons of reading material full with theories and intellectual speculations. The truth is, morality is not driven by anything, it is the one thing that drives everything else. Morality is the fundamental drive of being a civilized conscientious human, that rises through self-awareness and self-regulation.”

“Biases are nature's algorithm for the preservation of life, but unlike mechanical algorithms, nature's algorithm in human neuroanatomy is accompanied by the capacity to defy that predominant algorithm and write new ones with acts of self-regulation.”

“Your biology doesn't want you to be inclusive - your biology doesn't want you to be global - your biology doesn't want you to be civilized - or to put it simply, your biology doesn't want you to be human - because to be human requires to be unselfish, which is deemed by your biology as a threat to your personal survival. Hence, it pulls all its savage strings in every walk of your life, so that you act as much selfish and primitive as possible, because as far as your biology is concerned, being selfish and primitive is what kept your ancestors alive in the jungle.”

“Herman Pontzer, an evolutionary anthropologist at Duke, studies health among hunter-gatherer societies whose lifestyles are similar to those of our ancestors. He found that they generally exhibit excellent health in spite of following a wide range of diets. It doesn't matter if they get 80% of their calories from carbohydrates, or from animal fat, or from nuts and berries - almost all eat more fiber than the average American, but that is about the only difference. (This takes the wind out of the paleo diet.) Interestingly, they don't shun sugar, consuming it in the form of honey. Notably they don't have access to processed foods of or deep-fried foods.”

“The prefrontal cortex is what we use to se goals, make plans, divide a large project up into smaller pieces, exercise impulse control, and decide what we're going to pay attention to. As I mentioned earlier, the prefrontal cortex is the last region to develop in childhood and doesn't fully mature until well after puberty - into the late twenties. Because of it's involvement in impulse control, there have been several cases in which defense attorneys argued that eighteen-to-twenty-year-olds shouldn't be held responsible for law-breaking acts because they lack an adult like, mature prefrontal cortex that would allow them to exercise adult-like impulse control. The prefrontal cortex is also the first cortical region to show wear and tear as we get older. "That is why one of the most significant problems in older adults is the ability to keep track of thoughts and prevent stray ones from interfering," says Art Shimamura. "Brain fitness as we age depends significantly on maintaining a healthy and active prefrontal cortex. The more we engage this brain region during daily activities, the better we will be able to control our thoughts and think flexibly.”
