The links between Leftism, individualism, collectivism and hubris are simple but require a complex understanding of context to make sense of them.
Every creature has four basic behaviors known as the “four Fs” — fighting, fleeing, feeding and reproduction — which serve a singular goal, which since Charles Darwin wrote about it, we have described as “adaptation,” or finding a niche within its ecosystem where it can find regular nutrition at minimal risk of combat or predation.
For an animal, every action it takes is a risk. If it ventures out from safe hiding, it is exposed to predators. If it wanders into the territory of another animal of its species, it may get in a fight, and those contain at least a large component of rolling the dice. Its best guess about how an action will turn out determines its survival.
Those guesses in turn reflect how well the organism knows its world. If it is delusional or misinformed, it becomes prey. Consequently, every organism secretly wishes for independence from this state of constant stress. A mouse might imagine the ideal life as a giant field where there are no eagles and snakes, and there is enough grain to always be content.
Humans have an equivalent of this in Leftism. Leftism is a defensive ideology based on preventing others from becoming predators to the individual. It does this by removing social standards; this is what “equal” means: there are no standards, so whatever an individual does is acceptable, and no one can criticize those who are obeying the minimums of civilization (yes: job, shopping; no: murder, intolerance).
In this way, Leftism is a fundamentally anti-Darwinistic philosophy. It wants no social classes, because that way some have more power than others and can victimize them. It wants to make as many actions as possible acceptable, so that someone cannot be lowered in social status for their actions. It prioritizes the weak, broken and clueless so that everyone feels accepted.
When we recognize this basic psychology, it becomes clear why individualism leads to collectivism. Individuals band together in a gang that offers protection from those in the rest of society who might know better. This cult in turn demands allegiance, and so those individuals become slaves to forcing that ideology on others. It justifies itself by being universal, or agreed upon by all as a good thing.
At the root of this is hubris, or the desire of the human individual to be the most important thing in the world. The individual wants itself and its desires, judgments and feelings to come before social order, natural order and logical order. This means that there cannot be recognition that some people are better than others.
For this reason, Leftists idealize criminals, prostitutes, drug addicts, and the dysfunctional. They hate the good, powerful, strong, loving, beautiful and realistic people because those establish a de facto hierarchy. Their ideal is a vast grey lumpenproletariat in which everyone is equal and can do whatever they want, and society subsidizes them.
In thermodynamics, we might refer to this condition as “heat death,” because under it, people would have no reason to strive. Their efforts would be focused on the individual and would therefore not lead to anything that benefits civilization or the soul, except in the rare case of the genius artist, musician or thinker (which is why Leftists pretend to be all three).
Leftism — a subset of Crowdism — is a weaponized form of individualism that demands the individual be free from the burden of having to take realistic actions in the external world. It is a retreat from life, a fatalism, in which we create a new religion and ideology based on human individuals, not actions which adapt to reality.
It is the death of individuality, civilizations and species. This is why it is so addictive: it both promises freedom from death, and a certain path to death which seems easier than toughing it out and trying to survive as long as possible. In its wake, it leaves behind a domesticated, incurious species who exist at the subsistence level found throughout the third world.
