There is no such thing as insanity since there is no unitary “proper” function of the mind. The biggest cause of what people call insanity is ambition. For example, a person who does not speak yet physically can may simply be waiting for a world in which his words become worthwhile. By not speaking he is alerting others to this need – it’s his form of communication. Ambition often requires the sacrifice of many things, it is a peculiarly human form of cruelty. Insanity is a celebration of the dreamed world that the mind is unable to fully realize. Relatively successful applications of insanity are called “great art” but even this form of success is highly limited. Only the insane hold out the possibility of true success – every artist is a sell-out.
Society is a cage. Society is tyrannical. It requires that everything be in a particular place, set just so. Enforcing this are both judicial laws and social laws. Insanity is a method of freeing oneself. The other method is suicide.
Take a close look at people deemed “insane”. If you’re honest and can look past your discomfort what you’ll find is that these people have very strong wills. You’ll never know why this is the case if you believe in the myth of “mental disorder”.
Insane people are locked up not for their own good, but for the lesser humans to not have to be shamed by them. It’s the same reason blacks are locked up in America and third world people are oppressed and/or ignored – the rulers of the world only see what is formed in their image.
It’s not so much that insane people have “ordered” or “disordered” minds as that unlike the rulers they don’t have a calculated cynicism about the state of their mind. Since they don’t want to control people they have no need to form their mind into some predefined “order” that will lead them to “success” in society. Unlike the rest of us their minds are truly their own. For achieving that freedom they must be punished. “Mental institutions” are one tool of such punishment. Social banishment is the most common.
