About this listen
Focusing attention can help an animal find food or flee a predator. It also may have led to consciousness. Tracing evolution over millions of years, Michael S. A. Graziano uses examples from the natural world to show how neurons first allowed animals to develop simple forms of attention: taking in messages from the environment, prioritizing them, and responding as necessary.
Then some animals evolved covert attention - a roving mental focus that can take in information apart from where the senses are pointed, like hearing sirens at a distance or recalling a memory.
Graziano proposes that in order to monitor and control this specialized attention, the brain evolved a simplified model of it - a cartoonish self-description depicting an internal essence with a capacity for knowledge and experience. In other words, consciousness.
In this eye-opening work, Graziano accessibly explores how this sense of an inner being led to empathy and formed us into social beings. The theory may point the way to engineers for building consciousness artificially. Graziano discusses what a future with artificial consciousness might be like, including both advantages and risks, and what AI might mean for our evolutionary future.

one of the best books on consciousness
Consciousness and self-awareness will not be much mystical to you after reading this book. The brain makes a model of the attention schema the same way it makes a model of the body schema, or anything else. It is not hard to build a machine that is consciousness of one or two things. but it would still be a challenge to make it conscious of many things.
