So if I am understanding you, we infer that the trait of consciousness must have evolved because humans have it now and humans evolved. The humans that didn't have it must have been 'overloaded' (though we have no physical example or any discrete explanation of how this would take place or why they would die out).
Well. That doesn't explain the origins of consciousness. If you can point to a portion of the human body that encompasses "consciousness" and then show me how our current consciousness differs from that of a pre-man ape 10 million years ago, I will begin to understand your line of thinking. What part of the brain would have been overloaded by the information? It still doesn't explain why the brain invented a 'self' to help contain this chaos.
And I'm not trying to set up an impossible question just to cross my arms and smirk. Let's imagine you have perfect knowledge. What would be the pieces of information you currently have and the blanks that you still need to fill in with facts to come to your conclusion that consciousness evolved as a natural trait?
Like I mentioned in an earlier post, it boils down to one dividing question: is consciousness a distinct phenomenon, unexplainable by the total knowledge of all biological parts used in the process of generating consciousness?
With perfect knowledge of how the human brain operates, would we be able to explain consciousness?
Or to put the same ancient question yet another way: assuming you had perfect working knowledge of the human brain and could explain how all its neurons interacted, could we come to the scientific conclusion that all aspects of consciousness are rooted in physical properties? We would discover that no metaphysical or otherwise external influence or imprinting is necessary for human consicousness, that's the argument of materialism.
The nihilistic and absurd implications of what I describe above are philosophical questions, not rooted in empirical reality, so I want to make sure I understand the position in its own scientific terms.
In a manner of speaking, sure, you could say that all scales of the universe operate along the same patterns and equations, from the largest to the smallest particles, from the weakest to the most destructive releases of energy. This doesn't mean that a dust mote is actually a universe with people inside thinking these thoughts. I don't believe in a multiverse (but I'm happy to be convinced otherwise).
A "goal of existing" implies an arrow of time and entropy. Do either of these exist in the world of physics? We can observe their effects, but can you prove them in the same way that we would prove a higher/lower dimension or a 'consciousness'?
The cell's version of "conceptualizing" would be when it is responding mechanically to stimulus, that's it. The cell doesn't possess the biology to self-reflect on its own behavior, or its own biology, or its existence. The cell is still guided unknowingly by certain a priori instincts like the need to reproduce, the need to seek nutrients, the need to defend, and so forth. Chemicals don't decide whether or not to defend themselves. Minerals don't seek to reproduce. These behaviors cannot be explained simply by the physical structures and the chemical interactions that carry out the behaviors, even on a microscopic, single-celled level.
My answers will be short because I'm on the mobile.
I don't have knowledge of any kind other than my own guesses based on what I understand of evolution and what I read in 'Sapiens' about the origin of consciousness, as we understand it today.
In the book Sapiens, the Author states that the best explanation for hominids without conscious thought (the example he uses is Neanderthal man) is that, while they looked human, they had the same ability as apes, monkeys etc, in that they react to natural stimuli but can't process thoughts, ideas of future problems. For example, could you convince a monkey to give up his only banana on the promise that he would get 100 bananas in monkey heaven?
The evolution part comes from how evolution happens, which we know so I'll skip that part. The missing link between the Monkey-brained neanderthals and the conscious homo-sapiens, must be, in my mind, failed attempts at pure consciousness.
I see at this, imagine if you gave a monkey the power of thought and imagination. If that monkey, by the flick of a switch could think, feel and imagine all of what has happened to him. All of that emotion - which is just chemicals released from different parts of the brain - being released en masse would kill it outright.
Now let's say you're a new born hominid with a half/half consciousness (nature hasn't perfected it yet) you could potentially survive the first few moments of life before the rush of natural stimuli floods your consciousness and again, frying your brain in chemicals.
With us though, all of our natural stimuli reactions are dealt with by the mammalian brain; fight or flight, muscle twitches, movement of the body, or by the reptilian brain; which drives the desire for food, sleep, sex and air. Our consciousness is then responsible for filtering excess natural stimuli or though patterns, which simplifies the 3 million bits of data per second, down to about 120 bits, so that the brain can manage. Without this cognitive brain, we couldn't begin to do half of the complex tasks we do.
Somewhere between monkey-brain and us must have been a half way creature/race that lived pretty short lives or died outright because of the conditions. Unless they managed to retreat to somewhere where natural stimuli is at a minimum; underground.
I suppose that wasn't so short, or coherent Billymadisonnopoints. Gif
