Your right arm is useful in the battle; but when it comes to thinking you need my guidance. You have force without intelligence; while mine is the care for to-morrow. You are a good fighter; but is I who help Atrides select the time of fighting. Your value is in your body only; mine, in mind. And, as much as he who directs the ship surpasses him who only rows it, as much as the general exceeds the common soldier, so much greater am I than you. For in these bodies of ours the heart is of more value than the hand; all our real living is in that.
