Answer: William James, an early American psychologist, compared consciousness to a stream that is constantly changing yet always the same. It meanders and flows, sometimes where the person wills, sometimes not.
Step-by-step explanation:
William James (1842-1910) was an American philosopher and psychologist, known as the father of American psychology. He organized a psychology course and was the first educator to accomplish that in the United States.
The stream of consciousness is a metaphor that refers to the way thoughts flow through conscious mind. James first used this term in 1890, in his book, Principles of Psychology. In this work, he describes the uninterrupted flow of human feelings, thoughts and perceptions.
