The folly of Passion
"Men who deliberate on difficult questions ought to be free from hatred and friendship, anger and pity. When those feelings stand in the way, the mind can not easily discern the truth, and no mortal man has ever served his passions and his best interests. When you apply your intellect, it prevails. If passion possesses you, it holds sway and the mind is impotent."
....... Julius Caesar, 63 B.C.
