Cognition is a function of consciousness. The first factor it implies is therefore a state of consciousness wherein the cognition shall take place. Having elsewhere used the word 'feeling' to designate generically all states of consciousness considered subjectively, or without respect to their possible function, I shall then say that, whatever elements an act of cognition may imply besides, it at least implies the existence of a FEELING. [If the reader share the current antipathy to the word 'feeling,' he may substitute for it, wherever I use it, the word 'idea,' taken in the old broad Lockian sense, or he may use the clumsy phrase 'state of consciousness,' or finally he may say 'thought' instead.]
Jorge Agustín Nicolás Ruiz de Santayana y Borrás, known as George Santayana (December 16, 1863 – September 26, 1952), William James (January 11, 1842 – August 26, 1910) was an American philosopher and psychologist who was also trained as a physician. The first educator to offer a psychology course in the United States, James was one of the leading thinkers of the late nineteenth century and is believed by many to be one of the most influential philosophers the United States has ever produced, while others have labelled him the "Father of American psychology". Along with Charles Sanders Peirce and John Dewey, he is considered to be one of the major figures associated with the philosophical school known as pragmatism, and is also cited as one of the founders of functional psychology. A Review of General Psychology survey, published in 2002, ranked James as the 14th most cited psychologist of the 20th century.
