Conclusion

Let me introduce the first chapter of the book.


At the beginning of the lecture on 'Biological Humans', the author gave a common task to the groups of ten people.
After giving the joint report to me, I gave the same score to all group members.
But then a problem arose.
In times like these, there is always a nasty bystander who just watches with his arms crossed and only slightly comments on his colleagues' work.
As an educator, it was important to address this issue.
After much thought, I came up with an idea.
After receiving the report, I randomly selected one student and administered an oral exam, and gave the same score to all members of the group.
After this seemingly insignificant attempt, a tremendous change occurred.
Bystanders began to decrease.
A change was seen among the crew members, with each volunteering to be one another's teacher.
Moreover, not only the oral exam results but also the overall learning effect increased.


Why do students teach each other and encourage each other's learning?
Grameen Bank, founded by Muhammad Yunus, winner of the 2006 Nobel Peace Prize.
It lends small amounts of money, up to $150, to poor people.
It is an unsecured condition.
Although it is a debt in the name of an individual, the group is responsible.
If an individual does not repay the loan, the group community to which he belongs cannot borrow money in the future.
The author brought up the story of the Grameen Bank, which, despite being an unsecured loan, had a repayment rate of over 97 percent and helped lift a significant number of the 7 million poor people who borrowed money out of poverty.


Back then, when the primordial instinct to successfully hunt in small groups of ten or fewer in the wilderness was alive and well, when even one person's carelessness could lead to a breach in the encirclement, loss of prey, and starvation for all, my mistake was a matter of life and death, not only for me but for the group.
The criticism from colleagues that would pour in after a mistake could be so disgusting that it would kill us, and the subconscious that it became instinctive is still deeply rooted in our hearts today.
The author simply used this subconscious of the 'biological human' in his lectures.


I opened it thinking it was a general science book by a medical school professor and neuroscientist, but I was drawn into the author's insights that crossed the boundaries of humanities and science.
The author believes that “interesting stories are the keys that open a tightly closed brain,” and “with the belief that ‘stories’ have the potential to connect science and humanities, I organized the content in a story format so that all readers can become interested in science.” As the author says, the content of the book is deep, but it is also easy and smooth to read.
As the author hopes in the preface, I hope this book will be a good opportunity to think about many things about the environment, humans, and the 'biological self.'
