The word “consciousness” has several possible meanings depending on the context, be it philosophical, moral, medical, or other. For example: to be aware of oneself, or to do one’s duty with conscience, or to regain consciousness after a coma. Consciousness is often considered as the prerogative of human beings, and as more or less synonymous with reflective and emotional intelligence, associated with a perception of oneself and the reality of the external world. But given the emergence of consciousness from life, is it not more reasonable to admit that it can take on a more nuanced meaning than a simple “all or nothing” alternative: conscious or non-conscious. It is therefore important to define very precisely the meaning in which this word will be used here to differentiate it from the notions of intelligence, thought, perception, morality, or feeling.
