The brain develops dramatically during childhood. These neural changes occur in the child’s interaction with its environment. The brain becomes a brain that functions in the culture in which it develops. If a child is mistreated, if it is deprived of important forms of interaction, like language and care, the brain is deprived of its opportunities to develop. This can result in permanent damages.
The fact that the brain develops in interaction with culture and becomes a brain that functions in culture, raises the question if we can change the brain by changing the culture it interacts with during childhood. Can we, on the basis of neuroscientific knowledge, plan neural development culturally? Can we shape our own humanity?
In an article in EMBO reports, Kathinka Evers and Jean-Pierre Changeux discuss this neuro-cultural outlook, where brain and culture are seen as co-existing in continual interplay. They emphasize that our societies shape our brains, while our brains shape our societies. Then they discuss the possibilities this opens up for ethics.
The question in the article is whether knowledge about the dynamic interplay between co-existing brains-and-cultures can be used “proactively” to create environments that shape children’s brains and make them, for example, less violent. Environments in which they become humans with ethical norms and response patterns that better meet today’s challenges.
Similar projects have been implemented in school systems, but here the idea is to plan them on the basis of knowledge about the dynamic brain. But also on the basis of societal decision-making about which ethics that should be supported; about which values that are essential for life on this planet.
Personally I’m attracted by “co-existence thinking” as such, which I believe applies to many phenomena. For not only the brain develops in interaction with culture. So does plant and animal life, as well as climate – which in turn will shape human life.
Maybe it is such thinking we need: an ethics of co-existence. Co-existence thinking gives us responsibilities: through awareness of a mistreated nature; through awareness of our dependence on this nature. But such thinking also transcends what we otherwise could have imagined, by introducing the idea of possibilities emerging from the interplay.
Do not believe preachers of necessity. It could have been different. It can become different.
