In Victor Hugo's "Les Miserables," the author reflects on the nature of sin and morality, suggesting that humanity's fundamental law is to minimize sinning. While striving to be completely sinless may be an angelic aspiration, it remains an unrealistic goal for humans who are inherently flawed and prone to error. This acknowledgment of human imperfection highlights the constant struggle between moral aspirations and the reality of earthly life.

Hugo draws a powerful analogy between sin and gravity, indicating that sin is an unavoidable reality that weighs upon human existence. Just as gravity is a force that cannot be escaped, sin is an intrinsic part of the human condition. The discussion invites readers to contemplate the complexities of virtue and vice, emphasizing the importance of striving for goodness while accepting the limitations of human nature.
