The roots of psychology
The word psychology was formed by combining the Greek psychē (meaning “breath, principle of life, life, soul,”) with –logia (which comes from the Greek logos, meaning “speech, word, reason”). An early use appears in Nicholas Culpeper’s mid-17th century translation of Simeon Partliz’s A New Method of Physick, in which it is stated that “Psychologie is the knowledg of the Soul.” Today, psychology is concerned with the science or study of the mind and behavior. Many branches of psychology are differentiated by the specific field to which they belong, such as animal psychology, child psychology, and sports psychology.
