Lewis Thomas wrote a famous series of 29 essays for The New England Journal of Medicine and eventually published in 1974 as a book and entitled The Lives of a Cell; Notes of a Biology Watcher
The Lives of a Cell: (Title essay):
This essay focuses on how connected humanity is to nature and how we must make strides to understand our role. Thomas argues that even our own bodies are not solely ours since the mitochondria and other organelles are descended from other organisms. He creates a metaphor of the Earth as a giant cell itself with humans just as one part of a vast system.
Thomas, an elegant writer, was a physician, immunology researcher, dean, poet, etymologist, and essayist.
