Peterson's central message emphasizes the power of individual responsibility in navigating life's challenges and finding meaning. He argues that embracing responsibility, even in the face of suffering and chaos, is essential for personal growth and a fulfilling life. The book explores how this belief has been a driving force in Peterson's own life, from his rigorous self-improvement practices to his outspoken stance on social issues.

Drawing upon his background in psychology and mythology, Peterson posits that ancient stories and archetypes hold profound truths about the human condition. He argues that these narratives provide timeless wisdom and guidance for navigating the complexities of life, offering a framework for understanding our emotions, relationships, and place in the world. 'Savage Messiah' examines how Peterson's interpretations of these archetypes inform his views on masculinity, femininity, and the search for meaning.

A staunch advocate for free speech, Peterson views open and honest dialogue as crucial for a healthy society. He criticizes what he sees as attempts to stifle dissenting voices and argues that intellectual diversity is essential for challenging established norms and fostering progress. The book examines Peterson's controversial stance on Bill C-16, which he argued infringed upon free speech rights, and how this ignited a firestorm of debate, propelling him to the forefront of the culture wars.
