No, it isn't. A hypothesis is a testable, falsifiable prediction. Bicameralism is not that at all.
Yes, bicameralism is a hypothesis in Psychology. Like you or not.
You made a claim about people, calling them evil... Are you afraid to find out?... And stop pretending you know anything about me.
I didn't called you evil, Viviane. I called positivism an evil ideology. Positivism nihilism, hedonism, etc are evil ideologies. But they were made by an already defeated entity. So I'm afraid of nothing.
I'm not an anti-vaxxer, a only-prayer-heals-all, a Bible thumper, a JW or any "woo and deepitys".
I belong to an ancient kind of knowledge. One that have been around since the dawn of consciousness and it will be around until the end of times.
We wrote the Bible, Viviane. The most influential book in human history. This very site is made upon reasonings from it. We are not afraid of any ideology from this world.
We created your precious science. Even the language used by science is ours. We use science to achieve our task to name every specie so it must be in our holy language.
We call ourselves Ecclesia.
And we know something about you.
We know that you found very easy to get rid from "woo and deepity" of JWism and other supertistions. But you can't get rid from the thought of what is to die. You don't need to be indoctrinated to harbour this thought, it happens from nothing in your mind. At first you label this fear and doubt about death as simply as an instinctive defense mechanism. But you know it's not just an animal instinct because it works in a total different way. An animal can only feel this instinct in a situation of danger. But we can reason about this in a very safe and comfy place. We are the only specie that can do that. Why this trait in human mind cannot be traceable to any other species?
We can trace any trait of our anatomy with a lot of evidences. Why we can't do that with our minds?
Where's the sense of justice in us came from? The sense of liberty? The sense of infinity? The sense of our own death? From what animals can we trace these mind traits?
Why consciousness is an evolutionary advantage at all in a pure biological POV? Our consciousness can produce suicide, mass suicide and the destruction of the environment and much more energy waste. Evolution is economic so why our consciousness produces waste?
Why only Homo sapiens sapiens possess consciousness? There's other megabrains in nature too. Like dolphins and whales. Their brains could easily harbour rationality as humans.
Science cannot answer these questions and much more, Viviane. And these questions are not "woo and deepitys".
You can't harbour the idea of someday you'll not exist. Because a part of you simply can't assimilate that because is immortal. No matter how hard you try to convince yourself of your oblivion after death. You'll never achieve that, and you never be in peace fighting against this feeling.
You can prove this for yourself, you already knows that. You only have to accept what you already know, what you always knew.
