What happens

The Fifth Men develop a technique for directly inspecting the past through trance-like states, using specially bred and trained individuals as 'mediums.' Early attempts are dangerous and often fatal, but eventually the process is perfected, allowing explorers to experience past events through the minds of deceased organisms. This new ability profoundly affects their culture, giving them an intimate and vivid knowledge of history, but also causing despair as they confront the eternal persistence of past suffering.

Themes in this chapter

  • The Limits of Knowledge

    The chapter explores the difficulty and danger of accessing the past, and the limitations of the exploring brain's capacity to understand what it perceives.

  • Suffering and Redemption

    The discovery that past suffering is eternal causes despair among the Fifth Men, who are haunted by the tragic past despite their own near-perfect society.

  • Humanity and the Other

    The chapter touches on the relationship between the Fifth Men and past species, such as the Second Men and the Martians, as they observe their lives and experiences.
