Nature could have evolved in another way and not stumbled upon feelings. But it didn’t.
I have long been interested in human affect—the world of emotions and feelings—and have spent many years investigating it: why and how we emote, feel, use feelings to construct ourselves; how feelings assist or undermine our best intentions; why and how brains interact with the body to support such functions.
As for the idea, it is very simple: feelings have not been given the credit they deserve as motives, monitors, negotiators of human cultural endeavors. Humans have distinguished themselves from all other beings by creating a spectacular collection of objects, practices, and ideas, collectively known as cultures. The collection includes the arts, philosophical inquiry, moral systems and religious beliefs, justice, governance, economic institutions, and technology and science. Why and how did this process begin?
A frequent answer invokes an important faculty of the human mind—verbal language—along with distinctive features such as intense sociality and superior intellect. For those who are biologically inclined the answer also includes natural selection operating at the level of genes. I have no doubt that intellect, sociality, and language have played key roles in the process, and it goes without saying that the organisms capable of cultural invention, along with the specific faculties used in the invention, are present in humans by the grace of natural selection and genetic transmission. The idea is that something else was required to jump-start the saga of human cultures. That something else was a motive. I am referring specifically to feelings.
