My wrestling with various late-life questions that might be called “spiritual” has taken me to a fuller appreciation of evolution and our biological history. The sequence here, the process—or so it has seemed to me—is that I’ve been looking for answers and the result or goal has been a new appreciation of our past. Those who believe in traditional religions often describe a similar sequence: their search for meaning leads them to God. The pattern seems to be that the human impulse comes first, the connection with a spiritual something-larger follows.
But what if the sequence is actually the other way around, if the something-larger has been doing the prompting in some way, if what we experience as our search is the work of the “larger” force. This idea is quite common in Christianity. Christians often say, more or less, “I was looking for God, but of course it was God all the time who wanted me to find Him.”
Maybe a similar reversal makes some sense for naturalists who replace God with evolution and biological history. That is, perhaps it has been beneficial for our survival and reproductive success to be inclined towards thinking about such topics as how we got here, where we go when we die, what the essence of life is. Perhaps spiritual thinking has been adaptive.
One writer who has made this case is a commenter on this blog who goes by the name of Discovered Joys. He or she seems to be both a skeptic and a broad thinker. In a comment on a post, he describes how most of the inanimate,“stateless” processes that fill the universe take place without connection to the past; matter and energy do what they do without any “adjustments” to how those reactions have taken place in the past. However, a few “stateful” bits of matter—i. e., us—adjust our responses and processes according to memories of previous conditions. To make such adjustments successfully, it helps to have an understanding of how and why things come about as they do. Discovered Joys writes,
I think it likely that stateful organisms such as us are inclined (as a result of evolutionary processes) to be selected for building ‘narratives’, ‘rules of thumb’ etc. to improve our stateful responses. As a consequence we are conditioned to try and find meaning and purpose…. For me, the hunger for spiritualism (meaning and purpose) is an individual’s evolutionarily driven behaviour.
In other words, natural selection has fostered the rudiments of spirituality in us, the inclination to look deeply at how and why things have happened, because that tendency has been to our advantage for survival and reproduction.
A different connection is fleetingly suggested by a pair of sentences from a very different source. Nicholas Kristoff and Sheryl Wudunn’s A Path Appears: Transforming Lives, Creating Opportunity (2014) is a must-read about the current reformation in our knowledge of how to help other people effectively.
At one point the authors are discussing the well-established fact that our helping others benefits our own health because it creates social ties. Then they add this: “Maybe this deep-rooted social element in all of us explains our yearning for a life of meaning. We wonder about our purpose: we care about our legacy” (17).
In other words, maybe what happens is not that we help others in order to find a life of meaning. Maybe it’s the other way around: we seek purpose and meaning in the first place because unconsciously it prompts us to get out and make the social ties that are good for us. Kristoff and WuDunn don’t say more than that, but the “deep-rootedness” of the human social drive that is so important to our well-being does suggest that any quality that contributes to it, including spirituality, would have an evolutionary benefit.
Such discussions about evolution-driven spirituality are certainly speculative. Finding out if they have any foothold in reality would require a large study of whether people with so-called spiritual characteristics, whatever those may be exactly, are more successful at survival and reproduction than a random sample of the population. For all we know, the data may show that spirituality makes no difference at all in achieving evolutionary success. It may even carry a disadvantage; moody thoughtfulness about life and purpose might turn out to be a handicap for people struggling against hard circumstances. Still, the fact that spirituality is engrained in so many of us, even in our DNA, begs the question of why it got there.
