Grant to me, O Lord, to know what I ought to know, to love what I ought to love, to praise what delights you most, to value what is precious in your sight, to hate what is offensive to you. Do not suffer me to judge according to the sight of my eyes nor to pass sentence according to the hearing of the ears of ignorant men; but to discern with true judgment between things visible and spiritual, and above all things to enquire what is the good pleasure of your will.
-Thomas a Kempis (c. 1380-1471)
