We must seek remedies for rash judgements according to the causes from which they spring. There are some hearts sour, bitter and harsh by nature, that likewise make all that they receive sour and bitter, and turn (as the Prophet says) judgement into wormwood, (Amos vi,13) never judging their neighbour but with rigour and harshness: these have great need to fall into the hands of a good spiritual physician, for this bitterness of heart being natural to them, it is difficult to overcome it; and though in itself it is not a sin, but only an imperfection, it is nevertheless dangerous, because it introduces rash judgement and slander into the soul, and causes them to reign there.
— St. Francis de Sales, Introduction to the Devout Life, Chapter XXVIII, Rash Judgement
