Language is at once the most familiar and the most mysterious of human capacities. We use it effortlessly every day, to think, to feel, to persuade, and to connect, yet its origins, nature, and mechanisms continue to challenge our deepest intellectual inquiries. This book, On Language: Its Nature, Origin, and Acquisition, seeks to explore the many dimensions of this uniquely human phenomenon, uniting perspectives from linguistics, cognitive science, philosophy, and communication studies.
