Men in whom there is no love of truth might be despised, but that is pride. Replace contempt with compassion, these people are burning in hell, their lives are endless suffering in contrast to the rare pleasures that are no more than wood in the fire of their suffering.
It is dangerous to love a cowardly and weak person. Such people, believing that there is nothing to love them for, intuitively believe that only those who are worse and weaker than them can love them. This thought awakens in them pride and contempt for the lower. They become arrogant and aggressive.
Pride is contempt for imperfection. It seems to pride that things are imperfect and that they must become perfect. Pride despises those who do not strive for perfection. Pride judges things. He considers some things more perfect than others. Pride thinks itself a judge. Pride thinks it has the right to decide what can and cannot be lived. What to release energy, and what should die of hunger. What is beautiful and what is not.
Judge not, lest ye be judged. You know who's not on trial? Himself. When you judge, you become jealous and contemptuous. When you find contempt in others, a little later you find it in yourself. You start despising yourself, trying to kill a part of yourself, and that's impossible.
