I will dare to go on here. Q: What is the purpose of living/reproducing beings, and society/species of those beings, interacting within a system of natural selection?
Well, on the individual being level, per Dawkins, it's to spawn as much future biomass (protoplasm) having your own blueprint (genes, DNA) as possible. Likewise, on the society / species level, it is to establish as much future biomass having the generic features of the blueprints of its members (i.e., the genetic distinctions between species, e.g. birds vs mice). The evolution of greater sensitivity, greater environmental scanning capacity, greater and faster information processing capacity, greater power to react to such information, greater capacity to retain and to extract higher-level implications from such information and to guide future behavior with those implications - it's all to maximize biomass having genes as similar as possible to the bio-agent or bio-agent collective. Perhaps that means some cooperation with other species, to the degree that other species provide useful inputs for our species. But mostly, other species are either to be used as food, or to be fought and eliminated when they compete for limited resources without providing our species with more benefits than losses.
In the insect world, a trick was "learned" (through the usual natural selection trial and error) that allowed certain species to do amazingly well with regard to biomass. That trick is eusociality, behavior programmed to the point of individual death to protect the collective. It appears to have been amazingly successful in maximizing species biomass (although it does require that the 'selfish gene urge' be toned down in the individual). The species developed an intelligence not apparent to the individual. Amazing.
You'd think that these eusocial species would have taken it to the next level by developing information sensing and processing capacities along the lines of what the mammals were eventually able to do. In other words, you might think that eusociality would not have been given-up on, as info sensing, processing and response capacities improved through natural selection.
And yet . . . . it was. Why? Why don't humans behave more like bees and ants; why are they so individualistic, when clearly such individualism causes wars and homicides, and obviously reduces human biomass relative to what it could be? Why did natural selection, in its long-term wisdom, allow mammals and humans (as the epitome of all mammals) to desire comfort and individualism (i.e. "being free"), if those things reduce their biomass success? Why do ants and bees and termites settle for the minimum and don't flinch at self-sacrifice when the collective requires it; and yet humans demand air conditioning and self-actualization and fine wines and rights of self-defense?
Why didn't we strive to out-biomass them instead with our bounteous info processing capabilities? Where did the selfish-gene 'species intelligence' go wrong? Was it something in all that information that they swallowed down over the eons that twisted the process, that made them sense "something more" to existence (via some biologically-based 'consciousness trick' inside of their highly complex info processors)? Why did the gene selfishness (along with all kinds of other selfishness) go back to the individual level? Why all the renewed emphasis on "SELF", when selflessness was doing so well in the race to soak up sunlight, water, oxygen, carbon, etc.?
Yes, I do suspect that it was something embedded in the increasing amount of information that was processed as species developed over the eons, that turned species development away from eusocial cooperation and back towards "SELF", and concurrently towards appreciation of being. Appreciation to the point of craving, to desperate striving to hold on to it, even to the point of killing those fellow beings with very-similar genetics.
Yes, I am toying here with the notion that the "light of dualism" is behind this "information effect", an effect that caused a sharp turn somewhere along the slow path of natural selection. It is a "light of self" that caused increasing internecine violence as species developed (bears and gorillas fight each other more than sunfish and sunflower plants fight each other); a "light" that has brought its highest form, humankind, to the brink of depravity and nuclear self-extinction, or some other form of species collapse e.g. via the global warming that humankind caused and can't seem to stop. But that light has also inspired the distillation of beauty and wisdom and intelligence and - civilization. Which trend will win the race?
But then again - maybe I'm all wrong here. Natural selection is a tricky subject and I'm not an expert in it. Just a layman with some questions and half-assed speculations. A guy with a couple of rough thoughts to throw into the mix regarding "purpose".
