First published in 1890, this book established psychology as a science and served as the quintessential work in the field for decades. James' intricate studies and paradigm-shifting ideas transformed the way we look at human thought and action. The text covers the core concepts of what it means to be human - brain function, consciousness, discrimination, memory, sensation, imagination, reasoning, and instinct. The book is published in two volumes, the first containing Chapters I through XVI and the second continuing from XVII to XXVIII.
