From the Washington Post review by Brenna Maloney of the book by James Bridle titled “Ways of Being”:

James Bridle’s opening question is: What does it mean to be intelligent? There are many qualities we might list to describe intelligence: the capacity for logic, reasoning and comprehension; the ability to plan; problem-solving; emotional understanding; creativity. But one of the most significant definitions of intelligence is: what humans do. When we speak of something being intelligent, we typically mean something that operates at the same level and in the same manner as we do. We tend to think that humans are the sole possessors of intelligence. It is what separates us from “lower” beings.
