The Soul is not an exclusively intellectual quality. Yet, from the equation, matter is also a form of energy. Science holds that the creation or destruction of energy is not possible. The Bible testifies that energy in its pure form, is in the possession of intellect. Science is able to describe various forms of energy, yet cannot find its source or its primal form.
Energy implicates movement and activity.
Life expresses movement and goal. However, the spirit is able to reconstitute the whole Soul, since it is, the source of all possibilities, intellect and creativity. Since light occupies such a narrow part of the Electro-Magnetic spectrum, humans can not see spirit beings. What the prophets of ancient Israel beheld were visions and dreams in which they witnessed the glory of God and his messengers. This does not mean he got to see God.
