My ideas relate to the future and science fiction. It mostly turns around... bigger brains. Much bigger brains, the next step of evolution, either as alien beings or artificial intelligence. I am thinking the same magnitude of difference between a rat and a human, is found now with a human and the "bigger brains" race (where the human is the lesser being). I have been thinking that the bigger brains understand the universe at a level we cannot
imagine. But as a human myself I won't be able to describe what it is... Then, I thought that the "bigger brains" live even more in their own thoughts than humans do. They have theorized that the universe is essentially a subjective experience, and that what is real and makes sense is their own thought processes and how they think about the universe, without which it would have no meaning. In fact, according to them, it works as if all the purpose of the universe is to eventually produce such bigger brains that give substance to the it as now there is some intelligence to fathom existence over non-existence. Humans are seen lesser life forms barely sentient. In addition, the "bigger brains" have psychic powers; this is not magic, but the result of being able to generate deeper thoughts and understand the laws of universe at an unimaginable level. Humans psions are then just people that somehow are attuned or connected to some bigger brains, and for unfathomable reasons have the latter grant their wishes (the humans couldn't understand their reason; but a rat couldn't begin to think why you would put it in a maze so he finds food on his own...).
Nonetheless the story is about humans who have to deal with "bigger brains", and the world becomes extremely different, only because of them, although these beings seldom intervene in the physical realm. This would be a story about humans meeting alien gods, a sort of encompassing divine consciousness that will affect their lives and the resulting adventures.
But I need to think more what it could mean to think / perceive with the next step of evolution's brain. An arduous, if not impossible endeavour!
Well, this is my rough concept anyway.
