Do you know why "I will go against my nature and instinct"?

"I will go against my nature, my instinct, and love you forever" comes from the selfish gene written by Richard Dawkins, an English evolutionary theorist, which means that people are naturally selfish, but in order to fall in love with someone, they can go against their selfish nature.

In The Selfish Gene, the original sentence is: When newlyweds get married, don't put your hand on the Bible and say that no matter whether they are rich or poor, health and disease will accompany them to death. Instead, put your hand on the books Evolutionary Psychology and Selfish Gene and swear: "I will go against my nature and my instinct and love you forever."

Dawkins' breakthrough contribution in The Selfish Gene is to introduce the important part of this social theory based on natural selection to readers in simple and popular form and interesting language.

In this book, Dawkins introduces the main topics in social theory in detail, such as the concepts of altruism and egoism, the definition of selfishness in genetics, the theory of kinship, including the evolution of parent-child relationship and social insects, the theory of sex ratio, mutual altruism, deception and natural selection of gender differences.

At the same time, Dawkins defined the unit or level of biological evolution as gene based on the progress of biological research and his own understanding, and explained that the basic feature of gene is "selfishness" through the use of ethical language.
