In Rebecca McNutt's book "Bittersweet Symphony," the author emphasizes the profound importance of individual morality over external systems such as law, science, or religion. She argues that true guidance comes from a sense of decency that resides within each person, highlighting that moral integrity is paramount in navigating life's complexities. This perspective suggests that personal ethics can lead to a more just and compassionate society.

McNutt's assertion encourages readers to reflect on their own values and the role they play in their lives. By advocating for a morality rooted in decency, she challenges the notion that established structures are sufficient for ethical decision-making. Instead, she proposes that cultivating one's own moral compass is essential for personal growth and societal progress, urging a return to basic human kindness as the ultimate guiding principle.
