Adversity is a severe instructor, set over us by one who knows us better than we do ourselves, as he loves us better too. He that wrestles with us strengthens our nerves and sharpens our skill. Our antagonist is our helper. This conflict with difficulty makes us acquainted with our object, and compels us to consider it in all its relations. It will not suffer us to be superficial.
Edmund BurkeMan acts from adequate motives relative to his interest, and not on metaphysical speculations.
