> First of all, thanks for the compelling discussion so far.

Likewise thank you for the compelling discussion and clarifications.

> To be clear, I don't hold any strong position. All my previous comments are based on the assumption that the three premises I wrote in the very beginning of the first post are true, but I'm not arguing that those premises are true. I was just elaborating the implications if they were true: 1) To survive and to reproduce would be the closest thing to the ultimate purpose of life. 2) What traits we consider "good" or "bad" would actually be just what traits are beneficial for survival or not.

I think you need a few extra steps to get you from those premises to these conclusions. In fact, I'd suggest you may not even really be able to get from those premises to those conclusions, in particular I think you'd need to invoke "designers" (or "higher beings") imbuing purpose into the functional specifics of evolution to arrive there (thus contradicting one of those premises).

The premises as stated don't tell you much in the way of ascribing "purpose" to life, only how the mechanisms behind how it propagates and changes over time, just as Maxwell's equations do not define some "purpose" to electromagnetism but rather describe its evolution across time. And further the emergent systems that arise from these underlying processes, of primary importance for our conversation here consciousness and emergent from that society and civilization, need not owe all their properties to the mechanisms of the underlying systems (indeed this is what we often mean by emergence).

So ultimately I think that not only is survival not the "ultimate purpose," I think it's difficult to argue there is any intrinsic purpose there at all.

> So ultimately I think that not only is survival not the "ultimate purpose," I think it's difficult to argue there is any intrinsic purpose there at all.

Maybe I was not explaining it clearly enough, but I agreed with this. Similarly to what you said here, I said in the original post that to survive and to reproduce is more of a tautology than a purpose. What I meant is that if there must be a purpose of life, survival would be the closest thing to it, but in some strict senses of "purpose", it is not a purpose.

What's more interesting is the second implication, which suggests that there would be no objective morality if the three premises were true. I wonder if you agree that there's an objective morality. Or, to put it into a question, how do you think humans, almost universally, can distinguish good from bad?

Ah, well apologies I spent several replies only to be redundant :-).

I don't think there is an intrinsic value function we can perceive/verify writ into the universe. There could be one or many, but I don't think we're presently in a position to assert what it is with any degree of confidence beyond wild speculation. This doesn't leave us with pure subjectivity/relativism, I think it just means we need to use a priori means to arrive at value functions. And once you do reason yourself to a value function or combination of value functions there are objective (though often quite difficult to analyze) answers to its optimization.

So I don't think there can be pure objectivity in value assignment, however once you bootstrap into value propositions, which could be so universally recognized so as to be very difficult to argue against (the reduction of suffering for instance), there are objective answers to optimizing for those values.

> Or, to put it into a question, how do you think humans, almost universally, can distinguish good from bad?

Without rigor I think most people instinctively tend to distinguish good from bad (insofar as those words have real meaning) by way of empathy, by the recognition of one's own internal desires and suffering and joy and recognizing the same states in others. The golden rule if you will, it's about as inherent a moral compass as I can think of.

And this indeed could be traced back to evolutionary origins and our sociability as a species. It's also quite fallible, and at scale you can see it break down again and again (empathy is a face to face sort of mechanism and tends to struggle to maintain its hold at a distance over space and time and in large numbers we find ourselves congregating and competing in, and as already noted good/bad are pretty poor substitutes for the complicated situations we find ourselves in at scale, and our evolutionary toolset is rather lacking in getting us to pay attention to the nuance and working through optimization deliberately), thus I think one could give pretty good reasons why this should not be an overriding guiding value function but rather a sort of starter's pack.
