This is why empathy is a superior strategy to to selfishness.
But empathy is selfishness. If you realize you are empathetic or enjoy being empathetic, it doesn't matter how noble/divine your actions/thoughts are, you're still just basking in the thing you like same as any other selfish person. Awareness is unfortunately (or fortunately) inextricably linked to humanity (and to a lesser degree other life).
Not necessarily. Selfishness and symbiosis are not the same at all. At best selfishness is a part of symbiosis, but symbiosis is not purely selfishness. Selfishness usually takes the form of immediate thoughtless gratification at the expense of others and often themselves, resulting in net destruction of resources and overall quality of life for everyone involved long term. Symbiosis is an exchange of one cost which you can easily bear for a benefit which you can not easily produce.
It is closer to an exchange than being purely selfish. I believe this is where the idea of Karma came from, because the people who came up with the concept understood that selfishness creates a net loss that ripples though society and spreads out adding to a negative ambient sociological state that eventually reaches back to the perpetrator of that selfishness. Symbiosis requires some kind of awareness if not intelligence. Every living thing is capable of being selfish and consuming, often even self destructively. Even bacteria eventually had to learn eventually that they can't keep living if they destroy their host.
I'll have to respectfully disagree. I understand what you're saying and what you're saying is true but only at a superficial level, if you dig deeper you'll see that your idea breaks down. For one when somebody, knowingly does a 'good deed', it's a good deed according to that person. It's impossible for the doer to predict all possible ripple effects stemming from his action but he chooses to believe it is for the best. It is also impossible for the doer to know for certain the level of appreciation of the receiver. What you describe is how the world has always operated since the dawn of man but then it is possible that you believe the world is doing just fine as it is.
Empathy can exist but only through complete innocence and without any observer or external awareness.
No one said anything about good deeds. I used the words symbiotic exchange. Either way you define it, it is not that complicated. If you treat some one shitty enough times, they will themselves start going around and being shitty too in order to pass that negativity on to some one else. If you treat people well, they start treating other people well too because they have positivity to share. If it makes some ones life better or easier some how in addition to your own, it is a success, end of story. The acting party need not be aware of every ripple of causation that follows to contribute to the overall positive state of humanity, thus relieving some negative pressure that some other asshole created by being selfish as a result causing it to balance out.
Think of it like an aquifer. Some people just drink from it and use the water lowering the levels. If there weren't people processing the water to add water back into that aquifer, then everyone would go thirsty. Everyone who uses the water can try to conserve and use less, and some people can continue to just take more, but there is a limit to how much people can take before everything just breaks down, and eventually the takers will have nothing left to take along with the givers. Human happiness is a finite thing that is quantifiable and can be taken and given to people just like any other commodity. If you don't believe this to be true, just take a look at the entire marketing industry. It is designed to create malcontent in order to influence you to buy a product in order to relieve that negative tension.
As far as your last two sentences, I don't know what it is that I said that some how communicates to you that I think the world is fine the way it is. I made no such conclusions or implications either way regarding that, this statement is completely of your creation. Your last statement is just complete nonsense and is untrue. I am talking about doing things that are positive for yourself as well as others, I didn't say anyone had to be completely innocent or saintly. Good actions don't erase bad actions or vice-versa. A mass murderer can wake up one day and realize the error of their ways and start doing things that are positive for everyone, it doesn't make them a saint, it just makes them aware of how their actions effect others and willing to do something about it.
I'm sorry but I do not have the patience nor energy to elaborate further. Suffice it to say that my response addresses every single challenge you brought up in your comment. And as for your last comment well everything you talk about can still be resolved from my previous comment. However if you honestly think I am wrong then I most probably am.
