In "Welcome to the World, Baby Girl!" by Fannie Flagg, a character expresses skepticism about the potential for human nature to evolve. They argue that, despite centuries of philosophical thought and idealism, the fundamental traits of humanity remain unchanged. This perspective suggests a resignation to the idea that efforts to reform human behavior are often futile. The quote reflects a broader belief that humanity is inherently flawed and resistant to change. It encapsulates a sentiment of disappointment regarding the optimistic views some hold about the possibility of moral and behavioral improvement over time. Essentially, the speaker is highlighting the stubbornness of human nature, suggesting that real transformation is improbable given our historical consistency.

You got some idealist idea about man being some noble creature … and all this crap about how we can change human nature. You can't change it, you're beating your head against a brick wall. People have had a couple of million years to change and they ain't changed yet, have they?

This quote emphasizes the futility of trying to alter the inherent characteristics of humanity, pointing out a long-standing acceptance of human flaws as unchangeable over millennia.
