None of [the universe's] immensity is affected by what I think about it. It doesn't depend on being thought about. If it is true that our galaxy alone might contain 30 to 80 million earth-like planets, and if every one of them were occupied by sentient beings, it doesn't depend on what they're thinking, either. It all simply exists.
That is why the process of evolution is so compelling to me. On this planet, and probably countless more, inanimate atoms became molecules which formed cells and over billions of years those cells evolved into complex organisms which finally became viruses, plants, animals, salamanders, banyan trees and human beings. Without giving it any thought, with no way to think it, the universe brought into existence a way of making itself seen.
There is more than one way to see. A leaf turns to the light. A chimpanzee selects a piece of fruit. A fish sees a smaller fish. An eagle sees a rabbit. A dolphin rescues a sailor. A dog welcomes us home. While all of these actions are guided by a process falling under the general heading of Intelligence, humans seem to be fairly unique in our ability for conscious thought. We see, we know, and we know we know.
This is a blessing and it carries a price. To know you live is to know you die. Having studied several cats at close range over a period of years, I've concluded they don't give it a moment's notice. They know they want to live, which is why they get out of trouble as fast as they can. Then they take a nap.
I am not sure I believe that humans are the only form of life on this planet which is conscious of its consciousness but I find it truly awesome that sentient beings such as us exist in the universe at all.
And then I ask myself why should the earth be so special that such wonders exist nowhere else in the universe and I realize that to believe we humans are unique is the height of conceit. The belief that humans are the center of the universe, unique among all creation, is the ultimate human conceit .
Roger asks himself at the end of his post
... what good does it do me to think of the universe as an unthinking mechanism vast beyond comprehension? It gives me the consolation of believing I conceive it as it really is. It makes me thankful that I can conceive it at all. I could have been a pair of ragged claws, scuttling across the floors of silent seas. In this connection I find the Theory of Evolution a great consolation. It helps me understand how life came about and how I came to be. It reveals a logical principle I believe applies everywhere in the universe and at all levels: Of all the things that exist, animate and inanimate, some will be more successful than others at continuing to exist. Of those, some will evolve into greater complexity. This isn't "progress," it is simply the way things work. On this dot of space and in this instant of time, the human mind is a great success story, and I am fortunate to possess one. No, even that's not true, because a goldfish isn't unfortunate to lack one. It's just that knowing what I know, I would rather be a human than a goldfish. Some reject the Theory of Evolution because it offers no consolation in the face of death. They might just as well blame it for explaining why minds can conceive of death. Living things must die. That I can plainly see. That we are aware of our inevitable death is the price we must pay for being aware at all. On the whole, I think we're getting a good deal.
When I die, what happens? Nothing much. Every atom of my body will continue to exist.
Each of us is a wonder to behold, unique in our self-aware consciousness, but each of us is also just a small speck of stardust whose internal processes are an awe-inspiring dance known as life, a small temporary pocket of negative entropy in the universe which happens to be conscious of itself.
