Come on guys, let's drop the personal stuff. We can do better than throwing poo at each other I think.
Why is it not admirable to embrace base instincts? See this is where I fundamentally disagree with your position, and it seems familiar to the perspective of many left-wing people I know (family, friends, others) in that there is this tendency to avoid accepting what we are, namely an animal, and that these instincts and base impulses are somehow dirty and to be pushed down by 'enlightened' thinking that typically arises out of academic and social institutions dominated by left-wing and liberal minded people. Psychology can not be voted on democratically or molded politically, and neither can morality..
Humans evolved to operate in social groups of about 150 individuals. We can probably have a decent, cohesive society up to around that level because that 150 will consist of a lot of family/extended family, but scaling it up has been disastrous. And that is what we are seeing globally. We are animals, yes, and the type of animal we are is not egalitarian and "fair" or concerned with human rights or equality. We have evolved traits which compels us towards greed and accumulation of resources, excessive aggression and tendency towards organised warfare (Warrior hypothesis, warrior gene), bigotry and instinctive bias towards 'out-group' individuals (again, male warrior hypothesis) regardless of what comprises the 'in-group' and a tendency to focus on physical force to resolve conflict. To an extent, we see this sort of behaviour in our closest ancestors such as baboons and chimpanzees. All of these traits are why the human world is so rife with suffering and pain. They are not "bad" things, they are our animal nature and we should never try an forget our heritage. In fact, we should examine deeply the animals we evolved with and from to see what our nature truly is. It is not pretty but it also simply 'is'.
Why is it not admirable to embrace base instincts? Because some of our base instincts are the cause of immense suffering globally and not at all just for humans. Our base instincts drive capitalism, organised warfare, environmental degradation, resource disparity. Our animal nature did not evolve within the hugely scaled up society we accidentally find ourselves in, with every action having global consequences. We can't put the genie back in the bottle and return to smaller and more workable societies, so we either need to give up on our civilisation entirely or use reason to shape it into something that doesn't condemn the majority to bullshit, needless futile painful lives. You've written your thoughts on this world a few times, SS, and its never been especially positive- and I agree. This world is brutal, this is not a planet I would choose to live on. Its a ball of rock with everything running around eating everything else, life is not pretty or beautiful or a miracle, it is a competition to see who dies first.
If you cannot see that the global disaster that we see unfolding is caused by our "base instincts" than you are simply part of the problem.
