The preface to the original edition of Iron John outlines the cultural and personal landscape of manhood at the time of the book's writing. Bly discusses the crisis in the contemporary understanding of masculinity, highlighting how the images of manhood presented by popular culture are outdated and insufficient. He suggests that traditional images and myths of masculinity, found in stories and fairy tales passed down through generations, offer a richer and more nuanced understanding of what it means to be a man.

Bly argues that these traditional narratives offer valuable insights into aspects of masculinity that are overlooked or undervalued in modern society, such as the importance of initiation rites, the role of mentors, and the transition from the mother's domain to the father's realm. He emphasizes that these stories provide models of positive masculine energy and leadership that are missing from contemporary culture.

The preface makes it clear that Bly's intention is not to pit men against women or to advocate for a return to oppressive patriarchal structures. Instead, he aims to explore male initiation and identity as distinct yet related to the Women's Movement. Bly acknowledges the deepening grief and confusion among men in the face of industrial and social changes that have disrupted traditional modes of masculine initiation and identity.
