Is instinct a viable concept for contemporary psychology? At the turn of the 20th century the concept of human instinct was the focus of extensive discussion.

It is suggested that such an expanded account may be a valuable and necessary theoretical tool for broadening our understanding of human psychology as intimately connected to its evolutionary past.
