Deep dives
The importance of studying altered states of consciousness
Thomas Metzinger emphasizes the need for any valid theory of consciousness to include an explanation of altered states such as dreaming and drug experiences. He argues that consciousness is a biological process and highlights the role of the body in shaping our conscious experience. Metzinger introduces the concept of the Ego Tunnel, a metaphor for the fact that our conscious experience is internally generated and limited to a small portion of our overall brain activity. He also discusses the function of consciousness, suggesting that it allows for more flexible behavior. Metzinger raises concerns about societal reactions to our evolving understanding of ourselves and urges reflection on the ethical implications of newfound knowledge and capabilities in neuroscience and neurotechnology.
