Psyche is the function of the organized matter in the brain as in the same way urine is the function of kidneys but we can find this function not only in the human being, as the matter of fact the capacity of thinking exist specially in the superior mammals like dogs, cats, monkeys, chimps, dolphins, walles, and in many kinds of birds.
The capacity of thinking is not exlusive of the human being, it is exclusive of the complex brain and every animal with the complex brain can think as it is demostrated by the science.
The human being without brain can not think it means that the function of the brain is thinking as the greatest conquer of organized matter.
Long time ago several philosophers used to think that the human being was psyche contained by the matter. Today we know that the psyche is the function of the matter so if the question is are we psyche or matter? The answer is we are both.
