Who they are

William James was a psychologist and author whose Principles of Psychology examined conscious experience as an ongoing stream. In the chapter included here, he described thought as personal, changing, continuous and selective, arguing against beginning with isolated sensations. This contribution belongs to the intellectual history of consciousness and the methods used to describe it.

His framework provides historical context for later experimental accounts of conscious experience.
