I need ~10-12 hours of sleep to function optimally. Luckily people are mostly idiots and I still excel when malfunctioning. I sleep ~5 to 7 hours a day, most of the week, and I get dissociative episodes and the occasional delusion. I don't fall asleep too often, due to caffeine consumption. The only problem I have consists of turning in papers where my reasoning isn't always logical. Sometimes they don't notice and sometimes I get a bad grade - which I compensate by scoring perfectly at the test(s).

Why do I simply don't sleep 10 hours a day? Insomnia.

Mfw I'm 20, successful in my studies, have enough friends and I'm depressed all the time.

Question:

Did brains evolve many times independently or are they all descendants from one proto-brain?

If brains evolved several times then what types of brains are there?

I don't know but we have many hypothesis about it. Maybe we will never know because human nature is simply too complex or one day we will know and then all moral questions will be answered.

I read a little about it but please explain to me why this gap is really there.

The grounds on which we decide how a being ought to be is what will lead to it's good life and if more beings are involved then the solution of course is what will lead to the good (or best possible life) for all of them.

I simply can not see how we can divorce "good" from what it is supposed to be good for.

A knife is good for cutting. There isn't some ideal good in some kind of platonic space to which we can compare everything and decide if it resembles it or not. Instead we need to look at what is actually there and then decide what it needs for it's fruition.
