Questions & Answers

Q: Did the human brain evolve to think?

While the exact reason for brain evolution is still unknown, neuroscientists believe that the development of cognitive abilities, including thinking, was influenced by the emergence of hunting as a survival strategy during the Cambrian Period.

Q: How does writing a book differ from writing scientific papers?

Writing a book requires the ability to balance scientific accuracy with brevity and storytelling. It involves the exploration of fascinating tidbits of neuroscience and their connection to philosophical questions without losing the validity of the science.

Q: What can we learn from brain evolution?

Brain evolution is a complex process that involves changes in sensory abilities, head development, and the adaptation to hunting. It highlights the flexibility of human brains and the importance of environmental factors in shaping behaviors, both positive and negative.

Q: How does Lisa Feldman Barrett approach the concept of love and evil from a neuroscience perspective?

Barrett believes that love and evil are not fixed essences but rather complex phenomena influenced by environmental factors. While the brain's capacity for violence exists, so does the potential for kindness and altruism, showing the malleability of human behavior.
