Well... I am a "if a tree falls in a Forrest..." kind of guy and I got to thinking about belief. The more I think about it the more I think "belief" is more than a thought process. And do we actually chose to form beliefs?
Yes.
Evolutionarily speaking, why has this trait been passed down? Why do we need to formulate beliefs? We have the ability to reason, and rationalize.
We didn't at the beginning and that's a very important point to make. Early hominid cultures new at best 1/100000th of what we know about the world today. Their brains helped them develop a mechanism to help them control and make sense of the world around them. They may have believed early beasts were gods and rain could be summoned. These evolved into traditional folk tale and their presumably as old as humans themselves. Early Hominids actually believed in an after life and buried their dead with their belongings.
The reason we needed to believe something is because we needed foundation. We needed something to help us understand the world around us so we could operate off of it as a basis for our actions. And we evolved the art of storytelling and leadership from it and flourishing societies became of it, based on the belief of benevolent and manevolent spirits. Early tales of right and wrong. This helped us, believe it or not. It was the basis of many early societies. A belief.
We do not need to believe
Not anymore. We've learned quite a bit about life and our earth and we've found a much more solid basis in science. We have ways of testing whether a rain storm is a god or just the water cycle now. And as I stated before on, it starts out as a blind guess appeal to intuition; knowledge and experience. And early beliefs have been similar to this.
"My village has fallen sick. Sickness is divine punishment for crime. Therefore a criminal is among my village."
Because that logically makes sense if you know nothing about germ theory. But as we discovered much more about our world and discovered germs and bacteria and such, this belief has been proven to be inaccurate and as such invalid as of today.
We can rationalize is so because of reason.
Early rationalization was nowhere near as sharp as today. People believed the Earth was flat because intuitively when they look forward they saw a straight stretch of land. People believed the sun orbited the earth because intuitively they saw it move around. People believed the moon was a light in the sky because intuitively it glowed.
But their rationale was incorrect despite at the time making perfect sense. As knowledge moved forward these beliefs died off.
Because of our rational observance of " " we can understand what it is, and how to deal with it latter. Fire hot. Don't touch fire.
This is most likely the early intuition that got it all started. The human brain being able to understand the correlation between things. And began to go into overdrive since then.
Heck we still do it today.
But belief... Our beliefs actually guide and form who we are. If we believe " " is bad, we will guide our lives to keep from " ".
Higher intuition and cognitive development plus the benefits of high social structure and shared knowledge all play a huge role in that.
A belief is both introspective, and part of our environment. Also a belief carries meaning, a purpose, and emotion.
You're right.
Logic is raw. Has no feeling. Logic says if I flip my light switch, it is highly probable my lights will come on. There is no emotion in it.
Well yes, it's a tool. Tools don't really come with a joke in the wrapper.
No personal meaning if you catch my point. A belief however is like our logic given meaning, and assigned emotion.
Roll with that. A belief can use logic to be formed.
This made me wonder. Can other animals believe?
I'm sure that some can. Self aware animals like Pigs, Elephants, and dolphins I'm sure can believe.
I remember I was a door to door salesman and I met a lady and her dog. The dog was a rescue. Big fella. But however never let me approach to pet it. It didn't mind my female partner but me, no. Turns out the dog was fiercely abused by its previous owner so badly it no longer trusted any males and would do avoid them or keep them at distance. I've never seen an animal so traumatized and it made me both angry and sad.
But this example helped me see that animals also have a way of recognizing, learning, and forming opinions on a higher emotional and cognitive level. It's able to 1) recognize human males and 2) associate its torture and pain with human males and 3) act out of its self preservation based on its past experience.
Poor dog.
Or is it only humans, and why would we be the only species?
I don't think so.
Further still. Is the ability to believe part of our consciousness? Or who we are?
It's not unique to us. It most likely exists in other animals, it's just we're unique because we seem to be the only ones who think about it.
I loved the movie Chappie, because it asks the question of what our consciousness is. If we did download a person's consciousness into a sentient AI would that AI now be able to believe? Or would all the one's and zero's revert it back to raw logic? This renewed the entire question to me, do we actually chose to form beliefs, or are we hard wired?
You and
your brain are separate entities. You handle the autonomous actions and the decision making. Your brain... well everything else.
So the answer to your question is
both.
Thoughts pop in and out of your head because your brain is just having fun with you. You can of course concentrate on a certain topic and if your brain chooses not to fart you'll have a hard think but other times your brain will grab an ipod and put that song your really like on in your mind... on repeat... until it drives you crazy or makes you sing.
It'll start making you think about a random ex from years ago. It'll make you randomly sad.
You handle the looking with your eyes. Your brain handles the deciphering by using knowledge you gained.
Check this sentence out: fi yuo cna raed tihs, yuo hvae a sgtrane mnid too. Cna yuo raed tihs?
You didn't consciously decipher that, thank mr. brain and your knowledge of reading, phonetics, and linguistics or that would be gibberish to you. And also your eyes read everything upside down so thank brain for that too.

This next one caught me off guard.

Try bending your pinky without bending your ring finger.
Try your hardest to hold your breath for one hour.
The brain will always be behind you and clean up your mess and give you a hand. It's fascinating.
