English Prelate of the Roman Catholic Church, Archbishop of Liverpool
Man... has a body and a soul... it is a spirit, immortal, and endowed with intelligence and free will. Soul is not just another word for spirit. Animals have souls, but their souls are not spirits. Only man's soul is a spirit; in man is the only kind of spirit that is a soul... There is an obvious difference between a living human body and a corpse. That difference is the soul.
The fact of our being able to form abstract or universal ideas is, in itself, a proof of the immateriality, or, as it is technically called, the spirituality of the soul, a proof that the soul is, in its essence, independent of matter.
