We often argue about which of the two is more important. In regards to sustainability we wonder what is „the true nature“ of humans and if we can create a world that is more in line with this true nature. Although an interesting discussion, it becomes obsolete when we understand and become clear, that who and what we are is determined by our relationships, to others and the world, that one changes the other and that their is no hierarchie. Identity is formed in relationality. The logical conclusion to that thought is that there is no one true human nature, but that it is determined by the environment, becoming nurture. Nurture and nature are not separate. What‘s innately human is changing in relation to the environment, to the nurture.
