This is all Darwinian evolution really says in the end.
In the topic of morality, Allan, Neil, Lizzie and others use the same old con of claiming that morality is not accidents, its….and then they just trail off into a non-answer. I find this a very frustrating and telling habit of the materialist.
There is no “other” thing there. Unless you want to include an intelligence, or a destiny into the theory (which destroys the theory of materialism) you aren’t left with another aspect to why things are. You have accidents, that somehow formed a durable combination. Its such a dishonest aspect of materialism that when its not convenient they don’t want to admit this part. But in not admitting it, they struggle with saying anything to counter it. They can use words like emergence, or nature did it, but that’s meaningless. The materialist theory is that it is simply accidents that breed well.
Every time a materialist tries to claim there is more to it than that, when they need to have a stronger arguing basis, don’t be fooled by the dodge. That is all they have. Accidents. Sorry, to force them to accept their own reality.
