What is it?
Consciousness refers to those states of sentience and awareness that typically begin when we awake and continue until we go to sleep again or otherwise become “unconscious”
Consciousness is believed to be the result of the complex electrochemical interactions in the Brain. Our mental experiences, such as Emotions, fulfil some essential data-processing functions.
Y. N. Harari argued that consciousness is the biologically useless by-product of certain Brain processes. Similarly, consciousness may be a kind of mental pollution produced by the firing of complex Neural Networks. It doesn’t do anything. It is just there.
“Current orthodoxy holds that consciousness is created by electrochemical reactions in the brain and that mental experiences fulfil some essential data-processing function.” (Y. N. Harari)
