In The Republic, there is a passage that describes what qualities a judge should be endowed with. The conversation takes place with Socrates.
Socrates: ‘The best way for a doctor to acquire skill is to have, in addition to his knowledge of medical science, as wide and as an early acquaintance as possible with serious illness; in addition he should have experienced all kinds of disease in his own person and not be of an altogether healthy constitution. For doctors don’t use their bodies to cure other people’s bodies – if so, they cannot allow their health to be or become bad – they use their minds; and if their mental powers are or become bad their treatment can’t be good.’
‘But with a judge it’s a matter of mind controlling mind. And the mind should not be brought up from its youth to associate with wickedness, or to run a whole range of crimes in order to get first-hand experience on which to be able to judge them quickly in other people, as the doctor does with diseases of the body: on the contrary, the mind must, while it is still young, remain quite without experience of or contact with bad characters, if its condition is to be truly good and judgments just. That is why people of good character seem simple when they are young, and are easily taken in by dishonesty – because they have nothing corresponding in themselves to give them a sympathetic understanding of wickedness.’
The point that is being made here is that a mind that is not corrupt should remain so to be able to be a good judge, since early exposure to wickedness would disrupt its proper functioning and interfere with it.
When you are young, you are yet to be impressed upon by the world. Your assumptions about people are good. It is only when you get older that you see the maliciousness in others, and even in yourself.
But this innocence that Plato talks about, the good person who in their youth seems simple, is not something that is washed away by the transition from childhood to adulthood. There are many people who maintain this innocence of character despite their encounters with malice. They are either not exposed to an extreme enough event, or they are working hard to preserve their mental model of the world.
They prefer to remain where they are, trapped inside a simplistic understanding of people, for such an understanding allows them to trust, to take risks, and to form relationships. There is no good that can be gained from extreme skepticism – even if merited.
You should not distrust people, and avoid them at all costs – it is not pragmatic. You should instead understand them. And once you have acquired a sophisticated understanding of human nature, it is then time to integrate this knowledge into your belief system. To reconcile your cognitive dissonance, to accept that each individual is both virtuous and sinister. That each individual aims for the good, but is selfish and has destructive motivations.
The problem in politics can be summarized as follows: each side refuses to acknowledge their own dark sides. They frame the other side as evil, while thinking of themselves as good. And it is the same in social life. You have those who presume their own innocence indirectly when they cast aspersions on others. Social shaming induces guilt which can lead to reform, so it cannot be said that casting aspersions is altogether fruitless, but when it is done pathologically, without properly considering the situation in its entirety, without holding one’s own self culpable, without taking stock of one’s own lack of self-control and lack of virtue, then there can only be net negative consequence.
The simple, innocent youth who grows up to be an adult does not remain young, nor innocent, but in their minds, they often do. And it is this mismatch between reality (what is) and what is perceived that results in both internal tension and external hostility.
It seems like cliched advice to always look at oneself before criticizing others, but it is necessary to do so, to avoid self-deception. The person you should fear most is yourself, not others who you may or may not encounter. You are permanently attached to yourself, you cannot escape your own mind or body, and so it is important to know what you are, and what you are not.
