| notes)
“ We cannot refute the philosopher who would regard all such manifestations as so many physiological processes without any conscious accompaniment. For though every one is directly conscious of his own mental life, no one can experience directly the mental life of another. We cannot inspect directly the psychic processes that go on in other living beings, or in our fellow men. Mind is inferred from action, from behavior. Reactions, adjustments to environment, accompanied by consciousness, by intelligence in us, are rightly judged to have the same accompaniment in other beings, in our neighbours. ”
