“What makes machines, animals, and people smart?” asks the subtitle of Paul Thagard’s new book, Bots and Beasts. Not “Are computers smarter than humans? or “will computers ever be smarter than humans?” or even “are computers and animals conscious, sentient, or self-aware (whatever any of that might mean)?” And that’s unfortunate, because most people are probably more concerned with questions like those.

Thagard is a philosopher and cognitive scientist, and he has written many books about the brain, the mind, and society. In this one, he defines what intelligence is and delineates the 12 features and 8 mechanisms that he thinks It’s built from,comprise it which allows him toso that he can compare the intelligences of these three very different types of beings.

He starts with a riff on the Aristotelian conception of virtue ethics. Whereas in that case, a good person is defined as someone who possesses certain virtues; in Thagard’s case, a smart person is defined as someone who epitomizes certain ways of thinking. Confucius, Mahatma Ghandi, and Angela Merkel excelled at social innovation; Thomas Edison and George Washington Carver excelled at technological innovation; he lists Beethoven, Georgia O’Keeffe, Jane Austen, and Ray Charles as some of his favorite artistic geniuses; and Charles Darwin and Marie Curie serve as his paragons of scientific discoverers. Each of these people epitomizes different aspects of human intelligence, including creativity, emotion, problem solving, and using analogies.

On the frosty morning of Dec. 9, 1921, in Dayton, Ohio, researchers at a General Motors lab poured a new fuel blend into one of their test engines. Immediately, the engine began running more quietly and putting out more power.

The new fuel was tetraethyl lead. With vast profits in sight—and very few public health regulations at the time—General Motors Co. rushed gasoline diluted with tetraethyl lead to market despite the known health risks of lead. They named it “Ethyl” gas.

It has been 100 years since that pivotal day in the development of leaded gasoline. As a historian of media and the environment, I see this anniversary as a time to reflect on the role of public health advocates and environmental journalists in preventing profit-driven tragedy.
