It is only the enlightened ruler and the wise general who will use the highest intelligence of the army for the purposes of spying, and thereby they achieve great results.
God has bestowed upon you intelligence and knowledge. Do not extinguish the lamp of Divine Grace and do not let the candle of wisdom die out in the darkness of lust and error. For a wise man approaches with his torch to light up the path of mankind.
For wisdom is the property of the dead,
A something incompatible with life; and power,
Like everything that has the stain of blood,
A property of the living; but no stain
Can come upon the visage of the moon
When it has looked in glory from a cloud.
Most of our pocket wisdom is conceived for the use of mediocre people, to discourage them from ambitious attempts, and generally console them in their mediocrity.
