Qualia is even more fleeting and confusing concept than Consciousness. Consciousness encompasses the experience of 'qualia', the subjective, first-person experiences. The term refers to the individual instances of subjective, conscious experience, like the redness of a red apple or the pain of a headache. These experiences are inherently personal and impossible to communicate fully. However, we need to define and to understand those concepts, if we want to advance in our own understanding, and in recreating consciousness "artificially".
