이번 선정 도서는 "이토록 뜻밖의 뇌과학" 입니다.

세부조정과 가지치기 - 인간의 본질에 대한 생각


이토록 뜻밖의 뇌과학을 읽으면서 가장 무겁게 느껴진 것은 세부조정과 가지치기라는 개념입니다. 우리 인간이라는 종은 이 세부조정과 가지치기라는 개념 덕분에 굉장히 인간다우면서도 한편으로는 위태롭다는 느낌을 많이 받았습니다. 양육자, 사회의 책임감이라는 것이 뒷받침되지 않으면 우리 종은 여기까지 생존해올 수 없지 않았나 생각이듭니다.


우리 인간은 대략 25년에 걸쳐 배선이 마무리되고 온전한 뇌의 구조를 가집니다. 다른 종들은 상상할 수 없을 만큼 너무나도 긴 시간이 필요합니다. 우리의 뇌는 이렇게 오랜 기간이 지나야 완성될까요? 이토록 뜻밖의 뇌과학 저자의 추론으로는 문화적 사회적 지식이 한 세대에서 다음 세대로 효율적으로 흐르게 돕기 때문입니다.


뇌는 적극적으로 세상을 예측합니다. 생존을 위해서이죠. 그리고 스스로 더 나은 방향으로 수정할 수 있습니다. 이것이 우리가 오래도록 살아남을 수 있었던 이유가 아닐까요? 잘못된 방향은 스스로 예측을 수정하고 동시에 이를 경험화할 수 있는 자유를 가질 수 있습니다. 이 얼마나 멋진 인간 뇌의 본질, 우리의 본질인가요.

"

Why did a brain like yours evolve? That question is not answerable because evolution does not act with purpose––there is no “why.” But we can say what is your brains most important job. It’s not rationality. Not emotion. Not imagination, or creativity, or empathy. Your brain’s most important job is to control your body––to manage allostasis––by predicting energy needs before they arise so you can efficiently make worthwhile movements and survive. Your brain continually invests your energy in the hopes of earning a good return, such as food, shelter, affection, or physical protection, so you can perform nature’s most vital task: passing your genes to the next generation.


"

Social reality is a superpower that emerges from an ensemble of human brains. It gives us the possibility to chart our own destiny and even influence the evolution of our species. We can make abstract concepts, share them, weave them into a reality, and conquer just about any environment––natural, political, or social––as long as we work together. We have more control over reality than we might think. We also have more responsibility for reality then we might realize.

Its “informal essays” debunk misconceptions about what we call human nature and our belief that the brain’s primary purpose is to think. Instead, Barrett invites readers to use what they learn from these essays to consider “the kind of human you are or want to be.”


Barrett explains that our brains did not evolve toward any particular goal “because evolution does not act with purpose—there is no ‘why?’” Our brain’s most important function is not to be rational, emote, imagine or empathize. It’s to manage allostasis or the budgeting of body energy—“by predicting energy needs before they arise so you can efficiently make worthwhile movements and survive.” The brain evolved in this direction because “Creatures that predicted correctly most of the time, or made nonfatal mistakes and learned from them, did well. Those that frequently predicted poorly, missed threats, or false-alarmed about threats that never materialized didn’t do so well.”


She emphasizes the importance of family nurturance for individual growth and development, insisting that “a particular human brain in a particular human body, raised and wired in a particular culture, will produce a particular kind of mind. There is not one human nature, but many.” The brain’s ultimate job, she says, is to ensure that our cultural and social knowledge—our cultural inheritance—will “flow efficiently from generation to generation.”


Returning to the subject of how our brain’s purpose is to accurately react to predictors, the book zeros in on the role of memory in this process. Barrett describes memory’s function as the basis for effective prediction although it can have difficulty telling fact from fiction and, therefore, trigger dangerous decision-making. She explains the crucial difference between physical and social reality, positing that creating a society that succeeds in serving the needs of everyone involves brains that can: be creative, communicate effectively, reliably copy one another, cooperate, and compress and process data efficiently.


To promote brain health, she encourages us to value strong social connections, reduce chronic stress, take responsibility for our behavior, create a social reality that is healthy for us all, and care more effectively for our physical environment. Although this book deals with complex theories, it is full of fascinating examples, anecdotes and metaphors to illustrate the material whose weightiness is leavened by Barrett’s wit sprinkled liberally throughout the text. As a welcome surprise, Seven and a Half Lessons is part self-help book on how to manage our own quirky brains and part manifesto on how to move forward to heal this country’s political divisions.
