A quote
You and I will agree, I think, that outward things are sought for the satisfaction of the body, that the body is cherished out of regard for the soul, and that in the soul there are certain parts which minister to us, enabling us to move and to sustain life, bestowed upon us just for the sake of the primary part of us. In this primary part there is something irrational, and something rational.
