The only justice is to follow the sincere intuition of the soul angry or gentle. Anger is just and pity is just but judgement is never just.
We should not pretend to understand the world only by the intellect. The judgement of the intellect is only part of the truth.
Depend upon yourself. Make your judgement trustworthy by trusting it. You can develop good judgement as you do the muscles of your body - by judicious daily exercise. To be known as a man of sound judgement will be much in your favor.
