Old human dreams

For most of our history as a type, we used to live as a compliment for tribal fishermen. Modern humans have been around about 200,000 years ago, but agriculture, that is, agriculture, originated only 12,000 years ago. According to some estimates, we humans lived as a tribe, the fisherman’s university for more than 94 % of our existence. During that time, before planting, we were very busy trying to get enough calories to operate our big bodies (the human body on the big side of the animal kingdom) and to maintain our huge brains, which alone consume 20 % of daily calories. The food was rare. Many berries, fruits, and cross -term spoils were needed, to pay the high -calorie demands for our body. There was no reading (not even about 5,000 years), and a little time for any reflection. There were other priorities, and these priorities for which our brain developed. Planned for our mind, encrypted in our DNAIt is still for these priorities and not something like reading.

At that time, humans looked at mature banana as a real being, there is in a real world. It was just something to be eaten. The object was seen as a yellow crescent, with a diameter of about one inch. It is unlikely that there is an old human idea that the yellow of the being and the gentle taste of it was products from advanced cognitive systems, the visual system, olfactory The system, respectively. There is unlikely to have such a human thought that there is any “treatment of information” included when the banana is discovered. All there was bananas. There was no “information processing”.

The ancient humans believed that the way the world looks at the way the world is. Thus, they were “direct realistic”, who believe that what we envision is the way the world is already, independent of any Mental representationsand Mental imagesOr Meaning data. There was nothing “mental” about bananas. Our brain (is) is designed to be direct realistic and we do not spend time worrying about how bananas perceive or why is it required. The goal is to find yellow bananas and not green.

Today thanks to the progress in science and philosophyWe know that we imagine things as they are due to advanced treatment in the brain. This perception is an achievement of the brain and 120 billion neurons. Certainly, there are things there, but they are not exactly how they look for us. It appears to be somehow because of how our brain “represents” these things. With regard to taste, sugar = “good” while hydrogen peroxide = “bad”. A good example is heat. Thanks to developments in science, we know that heat is simply molecular movement. The higher the movement, the more heat. This is the kinetic theory of heat. But no one tests the heating of the movement, in the same way that no one is tested as a blue color as a frequency higher than a Red. (In physics, the difference between red and blue is simply a quantitative key, which includes frequency; for us, the difference is qualitative – and it cannot be explained to some extent.) Banana is only delicious for brains. Its flavor is a representation, created by a brain, leads an animal to eat more of it and its choice, for example, green banana or sulfur.

I often think about the daily experience of this old man. During the day, he did not have the slightest idea that the things and terrain that were considered considered in this way, with their countless colors and sounds, thanks to the brain and its advanced operations. But then I think about something else. At night, a magic thing happened, a thing that can challenge the beliefs of this person and can challenge the belief in direct realism: Dream. Eyes are closed, one He lies The bed, but one suffers from (somehow) a complete fact, is full of colors, things, discussions and desires. I wonder how this ancient person’s reaction was to suffer a dream. I wonder what I thought about dreams. Do you challenge everything or direct realism? Was she had presented an idea of the biological basis for our daily experiences?
