A day ago, I was in a Private Message with the DM of a Roleplay I wished to join. I will not divulge a name, but you know who you are. After a while, we turned slightly to the subject of Insanity. Realistic Insanity, not the type of Insanity shown through Media or exaggerations. What the DM said really peaked my interest on the subject, and I started to think about Insanity in general. I couldn't define it on my own, so I tried to use Google to help me. I could never really find a well-liked definition, so I began to simply think it through myself. I realized that Insanity could be most accurately expressed, not as a thing, but an idea. Ideas are never really universally defined in a dictionary, or a website. Instead, we each have a rough translation of the idea, but our own personal translation rarely matches with another. My own opinion of what Insanity is could differ vastly or minimally with yours. As I was thinking, I began to wonder if no one could truly define Insanity, to a point, except those that have succumbed to madness themselves. A madness so deep, so great, that nothing that came from their mouths could be brought to consideration. What if by truly understanding madness, truly understanding Insanity, one had to become completely and utterly insane themselves. They would be tortured with the information, knowing that they could never convince anyone else to believe them. Imagine yourself in such a situation, knowing something unknown by other people, yet never being able to share the knowledge, never being able to be taken seriously? It might drive one insane. Yet they would already be insane, wouldn't they? Thinking this way lead me to another thought: What if Insanity is simply the knowledge of something unknown, knowing something that no one else does? I'm not talking about discovering a new species, or realizing a potential medical breakthrough, or anything along those lines. I'm talking about knowing something so great, so awe-inspiring, so beautiful, yet so unlikely that no one will believe you. For example, Imagine we are all insane, every single one of us, living in a world without laws or reason, without constraints or restrictions, without gifts or benefits? Imagine that the lives we currently live, the lives we currently play out on this Earth are nothing but the inane, rambling thoughts of our Insanity? What if those we call "Insane" in this world are merely those that know the truth, those that know what the true reality is like? That is the type of knowledge I am talking about, that is the type of unknown that might drive one to Insanity, and that is my own personal opinion, my own personal definition of "Insanity": The knowledge of the unknown.
