It begins by understanding that we will never have an understanding of all those things. Neither omniscience nor perfection is going to be possible.
Isn’t there a wise adage that states, “Never say never.”?
I agree, we are never going to figure it all out in our lifetime and probably not in the foreseeable future. Therefore, let’s let that go and focus on the information and knowledge that is available to us and do the best we can with it.
But we have a number of useful cognitive tools we can use to help us achieve some degree of wisdom with which to apply whatever actual knowledge we may manage to gain or possess.
Literary fiction would be a great example. Fiction is a powerful vehicle for exploring the human condition, to essentially set up thought experiments that are put through their paces throughout the narrative. Whether aspirational or cautionary, values and ideals can be illustrated and easily disseminated for any to consider and evaluate. Those ideas that resonate may ultimately lead to social change.
... that science has done nothing to mitigate, and that industrialization has clearly exacerbated.
And yet we continue to fail in that regard as warfare, starvation, disease, and brutality break out regularly among humans all across the globe. Just as we have for over 100,000 years. We learn nothing but how to kill each other more efficiently thanks to the industrialized application of science-derived knowledge.
This is a charge that I strongly disagree with. You have been holding up Philosophy and Religion as the answer to the problems you have outlined, yet both have had millennia in which to “solve” these problems with no appreciable results. Science has only been on the scene for a few hundred years, and in that time we have seen the birth of humanism, liberal values, human rights, as well as great strides fighting disease as well as hunger.
Where do you see science creating these better humans and this better world? Star Trek is fiction. Where do you see the lack of art, philosophy, and religion making people wiser, and kinder, and less inclined to abuse and destroy each other? Where are you seeing scientists gathering together to discuss the potential moral harm their discoveries are enabling? Or the possible moral good their inquiries could be pursuing. Because I'm sure not seeing any of this.
There is currently a social taboo against creating better humans (This topic is addressed in Star Trek, btw). I suspect that you would not be in favor of eliminating sexual reproduction and pivoting solely to implantation of genetically modified human eggs. Since early childhood development can have a large impact on a person, you would also have to raise the genetically modified babies in a controlled environment to avoid undesirable behavioral contamination or an insufficiently stimulating environment. Heck, might as well hold on to them till they reach adulthood just to be sure. Of course there is also the issue during the experimental phase of what to do with the attempts that do not meet the mark. Oh, and the issue of what marks we should actually be shooting for. So what do you think? Shall we unleash the full force of scientific ingenuity to create better humans? No?
Well, if we’re not going to fiddle genetically with the ingrained default behaviors of humans then we have to do the best we can with the current lottery of sexual reproduction.
What is left to us then, to mitigate baseline human behavior, is socialization. How members of a society are socialized within that society strongly influences how the society behaves as a whole. Clinging to antiquated legacy belief systems stagnate society and make it difficult for society to adapt to ever changing societal conditions, be that through population growth, technology, etc. Any belief system that assigns firm answers to the unknown and unknowable, such as Religion, will always be a stagnating force and an impediment to solving the very issues to which you show great concern. Other beliefs that separate human beings into types, kinds, or affiliated groups also play into negative aspects of our instinctual behavior when expressed in our modern societies.
So that is the task, as I see it. Create a dynamic social system that successfully manages very large groups of unique individuals, that both meets the needs and wants of each individual, eliminates war, starvation, and disease, and appropriately handles those unique individuals who cannot learn to control urges for brutality against others. A daunting task I know, but I see this process as already occurring organically, naturally if you will, albeit slowly. Perhaps this process can’t be made to go any faster without inducing an actual catastrophe and we simply have to let nature take its course.
