Hi Newton! Consciousness remains a mystery to science. It is not easy to define. However, in my primordial understanding of life, I would say that consciousness refers to a state/ the feeling of being present, physically, emotionally and even subconsciously.
Consciousness is our personal interior awareness. It combines various subjective, signifying phenomena such as perception and cognition which seem to recapitulate lower levels of sensory awareness. The top level is really a meta-awareness of psychological meaning. It is directly (consciously) available to the subject herself in a teleological dialectic, which consists of voluntarily controlled activity and involuntarily interpreted sense which is received and projected.
