These are notorious but not sure how to order them. Anarchism (no rulers; absence of hierarchy) is both idealistic and worth striving toward. Moral judgments are relative. Nothing is right or wrong according to the universe. Humans create that weight. Free will does not exist (cannot exist). Every decision you make is due to factors outside of your control. It ultimately doesn't matter because it is still okay to criticize people. You still want what you want, and most people want to be liked and want to do well with others, and you can take advantage of that by pretending free will exists. The difference is understanding the difference being being angry because they could have made another choice and being angry because your anger sends a signal that will make them do what you want. One is an illusion that can lead to false conclusions like "If I hit them it will make them do better next time" while the other turns emotions into a strategic advantage. Justice is just a word people use to make themselves feel better about vengeance. "Doing your time", "getting yours", and so on are euphemisms used to mask sadistic pleasure at hurting someone else. Feeling like the books are balanced doesn't change state of the world. Killing a murderer does not always make the world a better place. Giving them a stable living environment, an education, and a chance at a productive job usually does. A murderer could become a nurse or a doctor and save lives, given the opportunity. That isn't justice. Some would say it is the opposite. People do not own their children. They aren't "your kids". You don't have a right to raise your child your way. Your child needs to be treated as a human being. If you can't do it to an adult, you can't do it a child. Children should be treated as people and allowed to learn in a natural way, not through violence and threats if they disobey. Invading foreign lands is always wrong. No exceptions. True knowledge of anything is impossible. Even if you knew all there was to know, you could not know that it was all there was to know. Therefore you should always have some doubt in every single thing you know and remain open to the possibility of alternatives for everything. Including that you are awake. As Skinner said, “The ultimate criterion for the goodness of a concept is not whether two people are brought into agreement but whether the scientist who uses the concept can operate successfully upon his material—all by himself if need be.” If you have a hallucination that no one else can see, and it cuts off your hand, and from then on you feel pain and can't use your hand -- it doesn't matter what others have to say about it. You lost your hand. If you live in an alternate reality from others, you have to work with the rules of the reality you see, others be damned. There is nothing wrong with being selfish if you are honest with yourself. It is impossible to act in an unselfish way. You do everything because you want to do it, or at least prefer it to the alternatives. Even acts of altruism are done to feel good about yourself and to feel that the world you live in is a better place. If you understand that we are just a bunch of selfish people warring for our own ideals, it becomes easier to seek your desires in an efficient manner instead of worrying if you have pure motivations. They don't exist. Faith is abhorrent. Faith leads to weakness and making weak decisions because it is easier to rely on something else than better yourself. If I could weed out one trait in all humanity, faith would be that trait. Let the doubt creep in. Nothing makes people smarter like thinking of the possibilities. If human nature cannot be changed by social forces, then eugenics is acceptable to counteract the terrible trend toward complacency and conservatism.
