About this book
What if a blush, a shrug or a snarl holds a clue to our animal past?
In The Expression of the Emotions in Man and Animals, Charles Darwin asks why feelings take visible shape. He watches dogs, cats, horses, monkeys and apes, alongside his own children and people from many cultures. Small movements become evidence in a larger argument about where human expressions come from.
Darwin argues that many expressions begin as useful actions and settle into habit. He builds his case around three principles, then explores grief, joy, anger, fear and surprise. At stake is a question close to every face we meet: how much of our language of feeling do humans share with one another and with animals?

From the 15-minute summary · Key idea 1
Expressions come from evolution, not special design
Before Darwin, most writers held that every species was created just as it is today. Sir Charles Bell taught that human facial muscles were a special provision for showing feeling. Darwin found this unconvincing. Apes carry the same facial muscles, and nobody would say monkeys were given them only to make grimaces.
He praises Dr Duchenne for careful photographs of faces moved by electric current. Yet even Duchenne said the Creator set each muscle moving by divine whim. Such an explanation fits every case, so it tells you nothing and stops the search.

What is The Expression of the Emotions in Man and Animals about?
It asks why feelings show in the face and body, and why they look alike across people and animals. Darwin offers three principles, habit, opposites and nervous overflow, and tests them on dogs, monkeys, infants, patients and travelers' reports.
What is the principle of antithesis in Darwin's book?
Antithesis means that a feeling opposite to one with a habitual expression calls out opposite movements, even if useless. His example is a dog that bristles and stiffens when hostile, then crouches and wags when it sees its master.
Did Darwin really use photographs and questionnaires?
Yes. He showed Duchenne's photographs of electrically moved faces to many people and noted their guesses. In 1867 he sent sixteen questions to observers worldwide and received thirty-six answers, which he used to judge which expressions are shared.
