I am without any doubt fascinated by brains and that thing we call consciousness. After years of listening to lectures and after reading a ton of articles and books, I can confidently say that we do not know what it is. Yet, we gave it a label.

Our brains needed to be able to operate with more then just instinct to achieve things so we and other animals have developed a consciousness to make decisions

I remember when I first learned about the id, the ego and the superego.
