J. Searle distinguishes eight features of consciousness: subjectivity; unity; intentionality; the distinction between the center and periphery of consciousness; the gestalt structure of conscious experience; the aspect of familiarity; mood; boundary conditions. Not all of them are taken appropriately; and all of them can be applied to mind. Mental life is accomplished as a stream of different events. Their empirical investigation is the subject of cognitive neurosciences. But, conceptually philosophical deliberation is prior to reflective evaluation, comparative results and final implications; it enables the possibility of understanding and interpretation of scientific explanations. Mind and brain are neither identical nor different. Psychic properties of a human being as a whole are not inherent just in his brain, or its parts, as well as exclusively in his mind.
