I Contain Multitudes
The Microbes Within US and a Grander View of Life
Overview of I Contain Multitudes
Dive into the microscopic universe living within us. Ed Yong's bestselling masterpiece transforms how we view microbes - from feared germs to essential partners. William Gibson called it "deeply strange, true, funny," while revolutionizing how science views everything from immune health to human behavior.
Key Themes in I Contain Multitudes
- human microbiome

- evolutionary partnerships
- metagenomic sequencing
Quotes from I Contain Multitudes
We are all ecosystems.
Every animal, every plant, is less of an individual and more of a community.
To study microbiomes is to study networks.
If you think about it, we’re all just mobile homes for microbes.
The question is not whether we can manipulate microbiomes, but whether we can do so safely and intelligently.

About the Author
About the Author of I Contain Multitudes
Edmund Soon-Weng Yong, Pulitzer Prize-winning science journalist and New York Times bestselling author of I Contain Multitudes: The Microbes Within Us and a Grander View of Life, merges rigorous scientific insight with accessible storytelling. Born in Malaysia and raised in the UK, Yong holds a biochemistry master’s degree from University College London, which fuels his expertise in exploring microbiology and symbiotic relationships.
His work as The Atlantic’s first staff science writer spans groundbreaking coverage of COVID-19 (earning the 2021 Pulitzer for Explanatory Reporting) and transformative books like An Immense World: How Animal Senses Reveal the Hidden Realms Around Us, a Carnegie Medal and Royal Society Prize winner.
Yong’s acclaimed Not Exactly Rocket Science blog and contributions to National Geographic, The New Yorker, and TED Talks cement his role as a bridge between complex science and public understanding. I Contain Multitudes, lauded by The Economist and NPR as a modern classic, revolutionized mainstream awareness of microbiomes, blending evolutionary biology with vivid narratives.
The book became a 2016 bestseller, translated into over 20 languages, and remains essential reading in university biology curricula. Yong lives in Oakland with his wife, science communicator Liz Neeley, and their corgi Typo.

FAQs About This Book
I Contain Multitudes explores the hidden world of microbes and their symbiotic relationships with humans, animals, and ecosystems. Ed Yong reveals how bacteria shape health, behavior, and evolution, challenging the notion of individuality. The book combines cutting-edge science with historical context, from Antonie van Leeuwenhoek’s discoveries to modern microbiome research.
Science enthusiasts, biology students, and curious general readers will appreciate Yong’s accessible storytelling. It’s ideal for anyone interested in microbiology, ecology, or the interconnectedness of life. Fans of Carl Zimmer or Rachel Carson will find similar insights into nature’s unseen forces.
Yes—it’s a Pulitzer Prize-finalist praised for transforming complex science into engaging narratives. Yong’s vivid examples, like glow-in-the-dark squid and coral reefs, make microbial partnerships tangible. Critics highlight its balance of wonder and scientific rigor.
- Symbiosis: Microbes and hosts depend on each other for survival (e.g., gut bacteria aiding digestion).
- Holobionts: Organisms as collective ecosystems, not isolated entities.
- Microbial manipulation: Using bacteria to combat diseases like Zika.
Yong adapts Carl Sagan’s timeline to show microbes dominated Earth’s history. If the universe’s lifespan were a year, humans appear in the final seconds—emphasizing microbes’ foundational role in evolution.
- Walt Whitman’s “I contain multitudes” reflects our microbial diversity.
- William Blake’s “world in a grain of sand” mirrors microbial ubiquity. Yong uses these to frame science within cultural context.
Yes. It shifts the “germ theory” paradigm, showing most microbes as allies. Yong critiques antibiotic overuse and highlights probiotics’ potential, urging a balanced view of microbial relationships.
It discusses fecal transplants, microbiome-tailored diets, and CRISPR-engineered bacteria. Yong cautions against hype but acknowledges promising research for treating autoimmune diseases.
Some argue Yong underplays microbial conflicts or oversimplifies symbiosis. However, most praise his nuance in avoiding romanticized “good vs. bad germ” narratives.
While An Immense World focuses on animal senses, Multitudes delves deeper into microbiology. Both emphasize interconnected ecosystems but target different scales of life.
With advances in personalized medicine and climate-linked diseases, understanding microbes remains critical. Yong’s work underscores microbes’ role in environmental resilience and human adaptation.
Absolutely. Yong’s storytelling—using squid, beetles, and breast milk as examples—provides a masterclass in making complex science relatable to non-experts.
