Are we our minds? Or are we our bodies? I believe we are our minds and never our bodies. The body is disposable. The mind, with the right protections and preservations, can live forever. The brain is a container for the mind and the mind is a neural network of memories.
Those memories, both the learned and the innate, form a perception of us and others. When the container is unexpectedly corrupted — when the brain is damaged by injury or disease or psychic trauma — strange things begin to happen.
