Tatyana Chernigovskaya emphasizes the importance of a deeper understanding of the human brain for better self-knowledge. She warns about risks associated with ignoring many unresolved questions about how the brain works. In a series of lectures called "Why Do We Need the Brain?" Chernigovskaya not only raises these questions, but also discusses possible answers. She asks about trust in our brain, the nature of consciousness, the possibility of its existence beyond biological frameworks, and discusses topics such as freedom of the individual and the nature of memory. She expresses doubts that humanity is ready for the near future, where it may be possible to manipulate memory, create people by order, interfere with the structure of memory and personality, and develop robots with consciousness as well as merge humans with computers. These lectures will help you make sense of and prepare for future challenges. Maybe everything isn’t as frightening as it seems?
