Philosopher and psychologist William James was the best known and most influential American thinker of his time. The five books and nineteen essays collected in this Library of America volume represent all his major work from 1902 until his death in 1910. Most were originally written as lectures addressed to general audiences as well as philosophers and were received with great enthusiasm. His writing is clear, energetic, and unpretentious, and is marked by the devotion to literary excellence he shared with his brother, Henry James. In these works William James champions the value of individual experience with an eloquence and enthusiasm that has placed him alongside Emerson and Whitman as a classic exponent of American democratic culture.
