I agree with this, since it is nigh identical to the opinion I expressed
here in the context of where "rights" come from. They come from instinct.
My main concern about the research is that it's sretching things to call the chimp behavior a belief in "justice." It's more like an instinctive prequel to it.
Exactly, but this bit of information, this insight, when it accompanies a search for meaning like what is the Buddha nature or why do I suffer, the search for deeper meaning, the seeking to end despair, etc. is of profound importance and I think central to what enlightenment is. What is ethics, what is moral, what is truth, are we basically good or evil, how these things are viewed create our attitude. Is life positive or negative, futile or does it have meaning. The lack of the experience of this realization, really just an attitudinal shift, a change in perspective, the collapse of duality and the onset of a sense of being, Is the source of existential suffering. We seek happiness not knowing that we are happiness itself, that the seeking of it is our misery. We were born to love life, to feel.
"There is a Sufi saying that no evil can befall a good person in this life or the next." But we were put down and told we were undeserving. The feeling that you were robbed of life's greatest gift, the joy of simply being, that could make a person very angry. To discover it was never really lost can changes things.
Thinking just now it occurred to me to put it like this: Enlightenment isn't like something you achieve. It's more like a realization of the relief that happens when for some reason you re-enter a state of mind absent your hitting yourself with a hammer.
