# VIII: The Martians explained — Last and First Men > Chapter companion for Last and First Men by Olaf Stapledon. ## What happens This chapter delves into the history and psychology of the Martians, explaining their motivations and the internal contradictions that led to their downfall. It describes their evolution into a single, unified species with a collective mind, their obsessive veneration of radiation and rigid materials like diamonds, and the resulting delusions that drove their invasion of Earth. The chapter contrasts the Martian collective psyche with human individuality, highlighting their lack of love, diversity, and true self-criticism, and suggests that their public mind, while powerful, was ultimately inferior and rigid. ## Themes in this chapter ### Humanity and the Other The chapter presents the Martians as a radically different form of intelligent life, contrasting their collective psyche and motivations with human individuality and diversity. ### The Limits of Knowledge The Martians' downfall is attributed to their self-deception and delusions, showing how even a highly intelligent species can be blinded by its own irrational beliefs and cultural obsessions. ### Society and Collective Identity The chapter explores the nature of a society built on absolute unity and uniformity, showing how the Martian collective mind, or 'Leviathan', stifles individual thought and progress. ## Character check-ins ### The Martians The chapter provides a detailed history and psychological profile of the Martians, explaining their collective mind, their obsession with radiation and diamonds, and the delusions that led to their invasion of Earth. ### The Martian Individual The chapter describes the individual Martian's experience, including their instinctive nature, their lack of sexuality, and their internal conflict between private thoughts and the demands of the collective 'super-mind'. ### The Martian Cloudlet The chapter details the physical and instinctive nature of the Martian cloudlet, including its vegetative functions, its complex instinctive impulses, and its potential immortality. ### The First Men The Martians are compared to the First Men, particularly in their shared capacity for delusion and their obsession with a particular concept (movement for the First Men, radiation for the Martians). ### The Second Men The Second Men are mentioned as having a more developed sense of self-consciousness and self-criticism compared to the Martians, highlighting a key difference in their psychologies. ## Key lines > In self-defence they persuaded themselves that since they were so much more admirable than the rest, the extermination was actually a sacred duty. To justify their brutal past, the Martians convinced themselves that their superiority made the genocide of other races a moral imperative. _This highlights the Martian capacity for self-justification and the origin of their delusional culture._ > Every diamond was therefore a supreme embodiment of the tense energy and eternal equilibrium of the cosmos, and must be treated with reverence. The Martians came to revere diamonds as sacred objects, believing they represented the perfect balance of cosmic energy. _This illustrates the irrational obsession with rigidity that motivated their invasion of Earth._ > The Martian super-individual was Leviathan endowed with consciousness. The collective mind of the Martians was like the biblical Leviathan, a powerful and terrifying entity brought to life. _This metaphor emphasizes the nature of the Martian public mind as a rigid, military-like force._ ## Links - HTML: https://www.betterreads.online/discover/last_and_first_men_se/chapters/viii-the-martians - Book: https://www.betterreads.online/discover/last_and_first_men_se - All chapters: https://www.betterreads.online/discover/last_and_first_men_se/chapters
