We have to be in this reality like this, there can't be any other way. What we all want is to feel happy, even those who suffer by trying to work out
some model, they do this so they can be happy again once the model is finished.
What if people could feel happy just by using their willpower? Most people can't, they need physical events for this to happen. So to eat a cake is
wanting to experience a taste which will bring about temporary happiness, just remembering that taste isn't sufficient (real enough) for the brain to
produce the chemicals that bring about this happiness. There has to be some reason behind it for the brain to produce those chemicals, even if the
brain can make them without having to eat a cake. That is, unless it's a chocolate cake or it's laced with some drug there are no chemicals in the
cake itself that would create any happiness. That reason is the idea of the cake, something which is not so much about nourishment but as something
that can be enjoyed, that will taste good.
This can all be traced back to the times when we didn't have the intellect as we have now. Animals need feelings of hunger to go out and get food then
they get a good feeling as a reward. They need to get that good feeling after having sex otherwise they wouldn't do it.
People need those feelings, one of the most important is that we are all real (not in a physical sense but more like having a personality or human
spirit) and exist in the same single shared world which can have the same truths for everyone, they don't want to think how one is only talking to the
image of the other in their own mind. The first creates feelings of not being alone and the chance of everyone uniting together under a single truth
(which many religions tried doing), the other implies we are forever alone in our own minds which might reflect the real world (both physical and our
assumptions about it) in some degree or until science and technology has made it possible for brains to link up to eachother and truly share brains.
And most importantly, the latter implies each individual has powers to make up their own truth, which makes people unpredictable and what is unknown
is usually feared.
