I think that @PARAprakrti hit the nail on the head. If the mind is larger than, transitional through, potentially separate and apart from the brain, the brains purpose seems to be to allow the mind to experience the physical world, and perhaps even to allow the mind to work on it. It may even be necessary to allow the mind to experience time in a linear manner.
But I feel like that is a theory we could discuss without the reference to the article – which I didn’t really follow in terms of the argument.
“Through this very human cognitive prism, our species was doomed to experience certain unshakable cognitive illusions – including feeling as though there are unseen moral forces that are concerned about us as individuals. Much like optical illusions, we can, through knowledge, accept that what we perceive does not reflect reality. But as the data mounts, it is becoming clear that even atheists experience the vague sense that they are here for a preconceived purpose, that their minds are endless, that there are inherent moral truths, and that the nonhuman world employs human justice.”
The sense of a preconceived purpose being a product of something inherent in us rather than produced by society generally seems like the precise thing Holmes would find distasteful. Even without reference to god or spirituality, social forces around us pushe us in one direction or another, our parents have expectations for us, successes are objectively measured in certain ways, etc. And by the time we’re able to communicate any feeling that a “plan” exists, we would have already been programmed by those around us to feel that way, regardless of a biological affiliation. The idea that the mind is endless is expected, as we never remember the beginning, and none knows what it’s like at the end – at least, none that can communicate it. When you’re in the middle of the ocean, no shore in sight, the ocean seems endless too. Inherent moral truths may be a product of biology, but that doesn’t really point in any direction at all. And the comment about the non-human world employs a human justice seems to come out of nowhere – it may be related to the previous comment about how atheists say things like the dead must feel vindicated, but that statement is really more likely a product of carelessness, and wouldn’t stand up to further questioning (at least, a good reasonable person wouldn’t defend it on further questioning).
“Is God a human instinct? It is instinctive for us to seek a grand, moralistic mind that is not there. God is the default stance. And as I describe in The God Instinct, the illusion of God solved a very specific evolutionary problem for our ancestors – that of reputation-harming (and thus gene-compromising) gossip. By inhibiting selfish behaviours that they feared would be punished by supernatural agents, our ancestors would have promoted their prosocial reputations among actual people. But unlike any previous generation, we are now in a position to correct that wayward stance through an informed understanding of why we sense a mental presence that never was.”
The argument that the idea of God solved a particular evolutionary problem for our ancestors is incredibly dangerous, I think. The author skirts social Darwinism with the reference. It’s also completely inaccurate and profoundly “Western” biased. There are still cultures of humans today that have beliefs that, although magical, aren’t based on the importance of a creator-god, any gods at all, or consider God to be concerned with our actions at all. That completely undermines the entire argument. But making the argument in face of that seems to indicate that the author believes that evolution is applicable to societies, as those that used God as a method of control of the social behavior of others in the group were able to survive, advance, and most importantly but not mentioned, conquer. It’s also not God but religion that is often used in that way, as the structures of religion are the ones that are able to order the moral system in such a manner that allow us to determine who deserves to be punished for their “evil” transgressions, and bring both the potential for punishment from our peers and that from God much closer together, as well as probable in our minds. Suffering by burning at the stake for allegedly unChristian behavior is a good way to get people to be scared of violating gods law, and literalize the punishments of hell. But Greek societies didn’t really have caring gods, and thought fate was fixed, and that the afterlife was inevitably hellish for incredibly good people unless they were actually heroic. That has nothing to do with maintaining a moral order so that we do not harm each other for our benefit – in fact, it’s more about ensuring that people will act only in their self interest in order to achieve greatness. And without any gods at all, our ancestors would have had a terribly effective time promoting pro-social behavior by declaring no afterlife at all, and using communal retribution to punish those who harmed others – imagine being sentenced to die for harm you’ve done when you’ve been taught that nothing follows this life.
Although in the end the author advocates setting aside the “use” of religious fear of persecution by God for a better understanding of why we have these senses, there is nothing at all that indicates that evolution produced the idea of God to help us survive (attributing intent in evolution), or that the general feeling or sensation of a grandness is a product of evolution, considering that the default is “god” for us because we are Western. Those without god, and who never had him, show that God is just as arguably one of the many products of our struggle to understand the universe, and as we get better and better at it we replace magical explanations for things with natural ones.
It’s proper that you quoted Holmes in the summary. He would have hated this article. ;-)
